A beacon of light
Placing a lit candle in a window to welcome friends and strangers is an old Irish tradition that took on greater significance when Mary Robinson was elected president of Ireland in 1990. At the time, Robinson placed a lamp in Áras an Uachtaráin — the official residence of Ireland’s presidents — noting that the Irish diaspora and all others are always welcome in Ireland. Decades later, a lit lamp remains in a window in Áras an Uachtaráin.
The symbolism of Robinson’s lamp was shared by Hashim Sarkis, dean of the MIT School of Architecture and Planning (SA+P), at the school’s graduation ceremony in May, where Robinson addressed the class of 2025. To replicate the generous intentions of Robinson’s lamp and commemorate her visit to MIT, Sarkis commissioned a unique lantern as a gift for Robinson. He commissioned an identical one for his office, which is in the front portico of MIT at 77 Massachusetts Ave.
“The lamp will welcome all citizens of the world to MIT,” says Sarkis.
No ordinary lantern
The bespoke lantern was created by Marcelo Coelho SM ’08, PhD ’12, director of the Design Intelligence Lab and associate professor of the practice in the Department of Architecture.
One of several projects in the Geoletric research at the Design Intelligence Lab, the lantern showcases the use of geopolymers as a sustainable material alternative for embedded computers and consumer electronics.
“The materials that we use to make computers have a negative impact on climate, so we’re rethinking how we make products with embedded electronics — such as a lamp or lantern — from a climate perspective,” says Coelho.
Consumer electronics rely on materials that are high in carbon emissions and difficult to recycle. As the demand for embedded computing increases, so too does the need for alternative materials that have a reduced environmental impact while supporting electronic functionality.
The Geolectric lantern advances the formulation and application of geopolymers — a class of inorganic materials that form covalently bonded, non-crystalline networks. Unlike traditional ceramics, geopolymers do not require high-temperature firing, allowing electronic components to be embedded seamlessly during production.
Geopolymers are similar to ceramics, but have a lower carbon footprint and present a sustainable alternative for consumer electronics, product design, and architecture. The minerals Coelho uses to make the geopolymers — aluminum silicate and sodium silicate — are those regularly used to make ceramics.
“Geopolymers aren’t particularly new, but are becoming more popular,” says Coelho. “They have high strength in both tension and compression, superior durability, fire resistance, and thermal insulation. Compared to concrete, geopolymers don’t release carbon dioxide. Compared to ceramics, you don’t have to worry about firing them. What’s even more interesting is that they can be made from industrial byproducts and waste materials, contributing to a circular economy and reducing waste.”
The lantern is embedded with custom electronics that serve as a proximity and touch sensor. When a hand is placed over the top, light shines down the glass tubes.
The timeless design of the Geoelectric lantern — minimalist, composed of natural materials — belies its future-forward function. Coelho’s academic background is in fine arts and computer science. Much of his work, he says, “bridges these two worlds.”
Working at the Design Intelligence Lab with Coelho on the lanterns are Jacob Payne, a graduate architecture student, and Jean-Baptiste Labrune, a research affiliate.
A light for MIT
A few weeks before commencement, Sarkis saw the Geoelectric lantern in Palazzo Diedo Berggruen Arts and Culture in Venice, Italy. The exhibition, a collateral event of the Venice Biennale’s 19th International Architecture Exhibition, featured the work of 40 MIT architecture faculty.
The sustainability feature of Geolectric is the key reason Sarkis regarded the lantern as the perfect gift for Robinson. After her career in politics, Robinson founded the Mary Robinson Foundation — Climate Justice, an international center addressing the impacts of climate change on marginalized communities.
The third iteration of Geolectric for Sarkis’ office is currently underway. While the lantern was a technical prototype and an opportunity to showcase his lab’s research, Coelho — an immigrant from Brazil — was profoundly touched by how Sarkis created the perfect symbolism to both embody the welcoming spirit of the school and honor President Robinson.
“When the world feels most fragile, we need to urgently find sustainable and resilient solutions for our built environment. It’s in the darkest times when we need light the most,” says Coelho.
Towards the 10th Summit of the Americas: Concerns and Recommendations from Civil Society
This post is an adapted version of the article originally published at Silla Vacía
Heads of state and governments of the Americas will gather this December at the Tenth Summit of the Americas in the Dominican Republic to discuss challenges and opportunities facing the region’s nations. As part of the Summit of the Americas’ Process, which had its first meeting in 1994, the theme of this year’s summit is "Building a Secure and Sustainable Hemisphere with Shared Prosperity.”
More than twenty civil society organizations, including EFF, released a joint contribution ahead of the summit addressing the intersection between technology and human rights. Although the meeting's concept paper is silent about the role of digital technologies in the scope of this year's summit, the joint contribution stresses that the development and use of technologies is a cross-cutting issue and will likely be integrated into policies and actions agreed upon at the meeting.
Human Security, Its Core Dimensions, and Digital Technologies
The concept paper indicates that people in the Americas, like the rest of the world, are living in times of uncertainty and geopolitical, socioeconomic, and environmental challenges that require urgent actions to ensure human security in multiple dimensions. It identifies four key areas: citizen security, food security, energy security, and water security.
The potential of digital technologies cuts across these areas of concern and will very likely be considered in the measures, plans, and policies that states take up in the context of the summit, both at the national level and through regional cooperation. Yet, when harnessing the potential of emerging technologies, their challenges also surface. For example, AI algorithms can help predict demand peaks and manage energy flows in real time on power grids, but the infrastructure required for the growing and massive operation of AI systems itself poses challenges to energy security.
In Latin America, the imperative of safeguarding rights in the face of already documented risks and harmful impacts stands out particularly in citizen security. The abuse of surveillance powers, enhanced by digital technologies, is a recurring and widespread problem in the region.
It is intertwined with deep historical roots of a culture of secrecy and permissiveness that obstructs implementing robust privacy safeguards, effective independent oversight, and adequate remedies for violations. The proposal in the concept paper for creating a Hemispheric Platform of Action for Citizen and Community Security cannot ignore—and above all, must not reinforce—these problems.
It is crucial that the notion of security embedded in the Tenth Summit's focus on human security be based on human development, the protection of rights, and the promotion of social well-being, especially for historically discriminated against groups. It is also essential that it moves away from securitization and militarization, which have been used for social control, silencing dissent, harassing human rights defenders and community leaders, and restricting the rights and guarantees of migrants and people in situations of mobility.
Toward Regional Commitments Anchored in Human Rights
In light of these concerns, the joint contribution signed by EFF, Derechos Digitales, Wikimedia Foundation, CELE, ARTICLE 19 – Office for Mexico and Central America, among other civil society organizations, addresses the following:
-- The importance of strengthening the digital civic space, which requires robust digital infrastructure and policies for connectivity and digital inclusion, as well as civic participation and transparency in the formulation of public policies.
-- Challenges posed by the growing surveillance capabilities of states in the region through the increasing adoption of ever more intrusive technologies and practices without necessary safeguards.
-- State obligations established under the Inter-American Human Rights System and key standards affirmed by the Inter-American Court in the case of Members of the Jose Alvear Restrepo Lawyers Collective (CAJAR) v. Colombia.
-- A perspective on state digitalization and innovation centered on human rights, based on thorough analysis of current problems and gaps and their detrimental impacts on people. The insufficiency or absence of meaningful mechanisms for public participation, transparency, and evaluation are striking features of various experiences across countries in the Americas.
Finally, the contribution makes recommendations for regional cooperation, promoting shared solutions and joint efforts at the regional level anchored in human rights, justice, and inclusion.
We hope the joint contribution reinforces a human rights-based perspective across the debates and agreements at the summit. When security-related abuses abound facilitated by digital technologies, regional cooperation towards shared prosperity must take into account these risks and put justice and people's well-being at the center of any unfolding initiatives.
The first animals on Earth may have been sea sponges, study suggests
A team of MIT geochemists has unearthed new evidence in very old rocks suggesting that some of the first animals on Earth were likely ancestors of the modern sea sponge.
In a study appearing today in the Proceedings of the National Academy of Sciences, the researchers report that they have identified “chemical fossils” that may have been left by ancient sponges in rocks that are more than 541 million years old. A chemical fossil is a remnant of a biomolecule that originated from a living organism that has since been buried, transformed, and preserved in sediment, sometimes for hundreds of millions of years.
The newly identified chemical fossils are special types of steranes, which are the geologically stable form of sterols, such as cholesterol, that are found in the cell membranes of complex organisms. The researchers traced these special steranes to a class of sea sponges known as demosponges. Today, demosponges come in a huge variety of sizes and colors, and live throughout the oceans as soft and squishy filter feeders. Their ancient counterparts may have shared similar characteristics.
“We don’t know exactly what these organisms would have looked like back then, but they absolutely would have lived in the ocean, they would have been soft-bodied, and we presume they didn’t have a silica skeleton,” says Roger Summons, the Schlumberger Professor of Geobiology Emeritus in MIT’s Department of Earth, Atmospheric and Planetary Sciences (EAPS).
The group’s discovery of sponge-specific chemical fossils offers strong evidence that the ancestors of demosponges were among the first animals to evolve, and that they likely did so much earlier than the rest of Earth’s major animal groups.
The study’s authors, including Summons, are lead author and former MIT EAPS Crosby Postdoctoral Fellow Lubna Shawar, who is now a research scientist at Caltech, along with Gordon Love from the University of California at Riverside, Benjamin Uveges of Cornell University, Alex Zumberge of GeoMark Research in Houston, Paco Cárdenas of Uppsala University in Sweden, and José-Luis Giner of the State University of New York College of Environmental Science and Forestry.
Sponges on steroids
The new study builds on findings that the group first reported in 2009. In that study, the team identified the first chemical fossils that appeared to derive from ancient sponges. They analyzed rock samples from an outcrop in Oman and found a surprising abundance of steranes that they determined were the preserved remnants of 30-carbon (C30) sterols — a rare form of steroid that they showed was likely derived from ancient sea sponges.
The steranes were found in rocks that were very old and formed during the Ediacaran Period — which spans from roughly 541 million to about 635 million years ago. This period took place just before the Cambrian, when the Earth experienced a sudden and global explosion of complex multicellular life. The team’s discovery suggested that ancient sponges appeared much earlier than most multicellular life, and were possibly one of Earth’s first animals.
However, soon after these findings were released, alternative hypotheses swirled to explain the C30 steranes’ origins, including that the chemicals could have been generated by other groups of organisms or by nonliving geological processes.
The team says the new study reinforces their earlier hypothesis that ancient sponges left behind this special chemical record, as they have identified a new chemical fossil in the same Precambrian rocks that is almost certainly biological in origin.
Building evidence
Just as in their previous work, the researchers looked for chemical fossils in rocks that date back to the Ediacaran Period. They acquired samples from drill cores and outcrops in Oman, western India, and Siberia, and analyzed the rocks for signatures of steranes, the geologically stable form of sterols found in all eukaryotes (plants, animals, and any organism with a nucleus and membrane-bound organelles).
“You’re not a eukaryote if you don’t have sterols or comparable membrane lipids,” Summons says.
A sterol’s core structure consists of four fused carbon rings. Additional carbon side chain and chemical add-ons can attach to and extend a sterol’s structure, depending on what an organism’s particular genes can produce. In humans, for instance, the sterol cholesterol contains 27 carbon atoms, while the sterols in plants generally have 29 carbon atoms.
“It’s very unusual to find a sterol with 30 carbons,” Shawar says.
The chemical fossil the researchers identified in 2009 was a 30-carbon sterol. What’s more, the team determined that the compound could be synthesized because of the presence of a distinctive enzyme which is encoded by a gene that is common to demosponges.
In their new study, the team focused on the chemistry of these compounds and realized the same sponge-derived gene could produce an even rarer sterol, with 31 carbon atoms (C31). When they analyzed their rock samples for C31 steranes, they found it in surprising abundance, along with the aforementioned C30 steranes.
“These special steranes were there all along,” Shawar says. “It took asking the right questions to seek them out and to really understand their meaning and from where they come.”
The researchers also obtained samples of modern-day demosponges and analyzed them for C31 sterols. They found that, indeed, the sterols — biological precursors of the C31 steranes found in rocks — are present in some species of contemporary demosponges. Going a step further, they chemically synthesized eight different C31 sterols in the lab as reference standards to verify their chemical structures. Then, they processed the molecules in ways that simulate how the sterols would change when deposited, buried, and pressurized over hundreds of millions of years. They found that the products of only two such sterols were an exact match with the form of C31 sterols that they found in ancient rock samples. The presence of two and the absence of the other six demonstrates that these compounds were not produced by a random nonbiological process.
The findings, reinforced by multiple lines of inquiry, strongly support the idea that the steranes that were found in ancient rocks were indeed produced by living organisms, rather than through geological processes. What’s more, those organisms were likely the ancestors of demosponges, which to this day have retained the ability to produce the same series of compounds.
“It’s a combination of what’s in the rock, what’s in the sponge, and what you can make in a chemistry laboratory,” Summons says. “You’ve got three supportive, mutually agreeing lines of evidence, pointing to these sponges being among the earliest animals on Earth.”
“In this study we show how to authenticate a biomarker, verifying that a signal truly comes from life rather than contamination or non-biological chemistry,” Shawar adds.
Now that the team has shown C30 and C31 sterols are reliable signals of ancient sponges, they plan to look for the chemical fossils in ancient rocks from other regions of the world. They can only tell from the rocks they’ve sampled so far that the sediments, and the sponges, formed some time during the Ediacaran Period. With more samples, they will have a chance to narrow in on when some of the first animals took form.
This research was supported, in part, by the MIT Crosby Fund, the Distinguished Postdoctoral Fellowship program, the Simons Foundation Collaboration on the Origins of Life, and the NASA Exobiology Program.
EFF Urges Virgina Court of Appeals to Require Search Warrants to Access ALPR Databases
This post was co-authored by EFF legal intern Olivia Miller.
For most Americans—driving is a part of everyday life. Practically speaking, many of us drive to work, school, play, and anywhere in between. Not only do we visit places that give insights into our personal lives, but we sometimes use vehicles as a mode of displaying information about our political beliefs, socioeconomic status, and other intimate details.
All of this personal activity can be tracked and identified through Automatic License Plate Reader (ALPR) data—a popular surveillance tool used by law enforcement agencies across the country. That’s why, in an amicus brief filed with the Virginia Court of Appeals, EFF, the ACLU of Virginia, and NACDL urged the court to require police to seek a warrant before searching ALPR data.
In Commonwealth v. Church, a police officer in Norfolk, Virginia searched license plate data without a warrant—not to prove that defendant Ronnie Church was at the scene of the crime, but merely to try to show he had a “guilty mind.” The lower court, in a one-page ruling relying on Commonwealth v. Bell, held this warrantless search violated the Fourth Amendment and suppressed the ALPR evidence. We argued the appellate court should uphold this decision.
Like the cellphone location data the Supreme Court protected in Carpenter v. United States, ALPR data threatens peoples’ privacy because it is collected indiscriminately over time and can provide police with a detailed picture of a person’s movements. ALPR data includes photos of license plates, vehicle make and model, any distinctive features of the vehicle, and precise time and location information. Once an ALPR logs a car’s data, the information is uploaded to the cloud and made accessible to law enforcement agencies at the local, state, and federal level—creating a near real-time tracking tool that can follow individuals across vast distances.
Think police only use ALPRs to track suspected criminals? Think again. ALPRs are ubiquitous; every car traveling into the camera’s view generates a detailed dataset, regardless of any suspected criminal activity. In fact, a survey of 173 law enforcement agencies employing ALPRs nationwide revealed that 99.5% of scans belonged to people who had no association to crime.
Norfolk County, Virginia, is home to over 170 ALPR cameras operated by Flock, a surveillance company that maintains over 83,000 ALPRs nationwide. The resulting surveillance network is so large that Norfolk county’s police chief suggested “it would be difficult to drive any distance and not be recorded by one.”
Recent and near-horizon advancements in Flock’s products will continue to threaten our privacy and further the surveillance state. For example, Flock’s ALPR data has been used for immigration raids, to track individuals seeking abortion-related care, to conduct fishing expeditions, and to identify relationships between people who may be traveling together but in different cars. With the help of artificial intelligence, ALPR databases could be aggregated with other information from data breaches and data brokers, to create “people lookup tools.” Even public safety advocates and law enforcement, like the International Association of Chiefs of Police, have warned that ALPR tech creates a risk “that individuals will become more cautious in their exercise of their protected rights of expression, protest, association, political participation because they consider themselves under constant surveillance.”
This is why a warrant requirement for ALPR data is so important. As the Virginia trial court previously found in Bell, prolonged tracking of public movements with surveillance invades peoples’ reasonable expectation of privacy in the entirety of their movements. Recent Fourth Amendment jurisprudence, including Carpenter and Leaders of a Beautiful Struggle from the federal Fourth Circuit Court of Appeals favors a warrant requirement as well. Like the technologies at issue in those cases, ALPRs give police the ability to chronicle movements in a “detailed, encyclopedic” record, akin to “attaching an ankle monitor to every person in the city.”
The Virginia Court of Appeals has a chance to draw a clear line on warrantless ALPR surveillance, and to tell Norfolk PD what the Fourth Amendment already says: come back with a warrant.
Chat Control Is Back on the Menu in the EU. It Still Must Be Stopped
The European Union Council is once again debating its controversial message scanning proposal, aka “Chat Control,” that would lead to the scanning of private conversations of billions of people.
Chat Control, which EFF has strongly opposed since it was first introduced in 2022, keeps being mildly tweaked and pushed by one Council presidency after another.
Chat Control is a dangerous legislative proposal that would make it mandatory for service providers, including end-to-end encrypted communication and storage services, to scan all communications and files to detect “abusive material.” This would happen through a method called client-side scanning, which scans for specific content on a device before it’s sent. In practice, Chat Control is chat surveillance and functions by having access to everything on a device with indiscriminate monitoring of everything. In a memo, the Danish Presidency claimed this does not break end-to-end encryption.
This is absurd.
We have written extensively that client-side scanning fundamentally undermines end-to-end encryption, and obliterates our right to private spaces. If the government has access to one of the “ends” of an end-to-end encrypted communication, that communication is no longer safe and secure. Pursuing this approach is dangerous for everyone, but is especially perilous for journalists, whistleblowers, activists, lawyers, and human rights workers.
If passed, Chat Control would undermine the privacy promises of end-to-end encrypted communication tools, like Signal and WhatsApp. The proposal is so dangerous that Signal has stated it would pull its app out of the EU if Chat Control is passed. Proponents even seem to realize how dangerous this is, because state communications are exempt from this scanning in the latest compromise proposal.
This doesn’t just affect people in the EU, it affects everyone around the world, including in the United States. If platforms decide to stay in the EU, they would be forced to scan the conversation of everyone in the EU. If you’re not in the EU, but you chat with someone who is, then your privacy is compromised too. Passing this proposal would pave the way for authoritarian and tyrannical governments around the world to follow suit with their own demands for access to encrypted communication apps.
Even if you take it in good faith that the government would never do anything wrong with this power, events like Salt Typhoon show there’s no such thing as a system that’s only for the “good guys.”
Despite strong opposition, Denmark is pushing forward and taking its current proposal to the Justice and Home Affairs Council meeting on October 14th.
We urge the Danish Presidency to drop its push for scanning our private communication and consider fundamental rights concerns. Any draft that compromises end-to-end encryption and permits scanning of our private communication should be blocked or voted down.
Phones and laptops must work for the users who own them, not act as “bugs in our pockets” in the service of governments, foreign or domestic. The mass scanning of everything on our devices is invasive, untenable, and must be rejected.

After Years Behind Bars, Alaa Is Free at Last
Alaa Abd El Fattah is finally free and at home with his family. On September 22, it was announced that Egyptian President Abdel Fattah al-Sisi had issued a pardon for Alaa’s release after six years in prison. One day later, the BBC shared video of Alaa dancing with his family in their Cairo home and hugging his mother Laila and sister Sanaa, as well as other visitors.
Alaa's sister, Mona Seif, posted on X: "An exceptionally kind day. Alaa is free."
Alaa has spent most of the last decade behind bars, punished for little more than his words. In June 2014, Egypt accused him of violating its protest law and attacking a police officer. He was convicted in absentia and sentenced to fifteen years in prison, after being prohibited from entering the courthouse. Following an appeal, Alaa was granted a retrial, and sentenced in February 2015 to five years in prison. In 2019, he was finally released, first into police custody then to his family. As part of his parole, he was told he would have to spend every night of the next five years at a police station, but six months later—on September 29, 2019—Alaa was re-arrested in a massive sweep of activists and charged with spreading false news and belonging to a terrorist organisation after sharing a Facebook post about torture in Egypt.
Despite that sentence effectively ending on September 29, 2024, one year ago today, Egyptian authorities continued his detention, stating that he would be released in January 2027—violating both international legal norms and Egypt’s own domestic law. As Amnesty International reported, Alaa faced inhumane conditions during his imprisonment, “including denial of access to lawyers, consular visits, fresh air, and sunlight,” and his family repeatedly spoke of concerns about his health, particularly during periods in which he engaged in hunger strike.
When Egyptian authorities failed to release Alaa last year, his mother, Laila Soueif, launched a hunger strike. Her action stretched to an astonishing 287 days, during which she was hospitalized twice in London and nearly lost her life. She continued until July of this year, when she finally ended the strike following direct commitments from UK officials that Alaa would be freed.
Throughout this time, a broad coalition, including EFF, rallied around Alaa: international human rights organizations, senior UK parliamentarians, former British Ambassador John Casson, and fellow former political prisoner Nazanin Zaghari-Ratcliffe all lent their voices. Celebrities joined the call, while the UN Working Group on Arbitrary Detention declared his imprisonment unlawful and demanded his release. This groundswell of solidarity was decisive in securing his release.
Alaa’s release is an extraordinary relief for his family and all who have campaigned on his behalf. EFF wholeheartedly celebrates Alaa’s freedom and reunification with his family.
But we must remain vigilant. Alaa must be allowed to travel to the UK to be reunited with his son Khaled, who currently lives with his mother and attends school there. Furthermore, we continue to press for the release of those who remain imprisoned for nothing more than exercising their right to speak.
Abusing Notion’s AI Agent for Data Theft
Notion just released version 3.0, complete with AI agents. Because the system contains Simon Willson’s lethal trifecta, it’s vulnerable to data theft though prompt injection.
First, the trifecta:
The lethal trifecta of capabilities is:
- Access to your private data—one of the most common purposes of tools in the first place!
- Exposure to untrusted content—any mechanism by which text (or images) controlled by a malicious attacker could become available to your LLM
- The ability to externally communicate in a way that could be used to steal your data (I often call this “exfiltration” but I’m not confident that term is widely understood.)...

How the brain splits up vision without you even noticing
The brain divides vision between its two hemispheres — what’s on your left is processed by your right hemisphere, and vice versa — but your experience with every bike or bird that you see zipping by is seamless. A new study by neuroscientists at The Picower Institute for Learning and Memory at MIT reveals how the brain handles the transition.
“It’s surprising to some people to hear that there’s some independence between the hemispheres, because that doesn’t really correspond to how we perceive reality,” says Earl K. Miller, Picower Professor in the Picower Institute and MIT’s Department of Brain and Cognitive Sciences. “In our consciousness, everything seems to be unified.”
There are advantages to separately processing vision on either side of the brain, including the ability to keep track of more things at once, Miller and other researchers have found, but neuroscientists have been eager to fully understand how perception ultimately appears so unified in the end.
Led by Picower Fellow Matthew Broschard and Research Scientist Jefferson Roy, the research team measured neural activity in the brains of animals as they tracked objects crossing their field of view. The results reveal that different frequencies of brain waves encoded and then transferred information from one hemisphere to the other in advance of the crossing, and then held on to the object representation in both hemispheres until after the crossing was complete. The process is analogous to how relay racers hand off a baton, how a child swings from one monkey bar to the next, and how cellphone towers hand off a call from one to the next as a train passenger travels through their area. In all cases, both towers or hands actively hold what’s being transferred until the handoff is confirmed.
Witnessing the handoff
To conduct the study, published Sept. 19 in the Journal of Neuroscience, the researchers measured both the electrical spiking of individual neurons and the various frequencies of brain waves that emerge from the coordinated activity of many neurons. They studied the dorsal and ventrolateral prefrontal cortex in both hemispheres, brain areas associated with executive brain functions.
The power fluctuations of the wave frequencies in each hemisphere told the researchers a clear story about how the subject’s brains transferred information from the “sending” to the “receiving” hemisphere whenever a target object crossed the middle of their field of view. In the experiments, the target was accompanied by a distractor object on the opposite side of the screen to confirm that the subjects were consciously paying attention to the target object’s motion, and not just indiscriminately glancing at whatever happened to pop up on to the screen.
The highest-frequency “gamma” waves, which encode sensory information, peaked in both hemispheres when the subjects first looked at the screen and again when the two objects appeared. When a color change signaled which object was the target to track, the gamma increase was only evident in the “sending” hemisphere (on the opposite side as the target object), as expected. Meanwhile, the power of somewhat lower-frequency “beta” waves, which regulate when gamma waves are active, varied inversely with the gamma waves. These sensory encoding dynamics were stronger in the ventrolateral locations compared to the dorsolateral ones.
Meanwhile, two distinct bands of lower-frequency waves showed greater power in the dorsolateral locations at key moments related to achieving the handoff. About a quarter of a second before a target object crossed the middle of the field of view, “alpha” waves ramped up in both hemispheres and then peaked just after the object crossed. Meanwhile, “theta” band waves peaked after the crossing was complete, only in the “receiving” hemisphere (opposite from the target’s new position).
Accompanying the pattern of wave peaks, neuron spiking data showed how the brain’s representation of the target’s location traveled. Using decoder software, which interprets what information the spikes represent, the researchers could see the target representation emerge in the sending hemisphere’s ventrolateral location when it was first cued by the color change. Then they could see that as the target neared the middle of the field of view, the receiving hemisphere joined the sending hemisphere in representing the object, so that they both encoded the information during the transfer.
Doing the wave
Taken together, the results showed that after the sending hemisphere initially encoded the target with a ventrolateral interplay of beta and gamma waves, a dorsolateral ramp up of alpha waves caused the receiving hemisphere to anticipate the handoff by mirroring the sending hemisphere’s encoding of the target information. Alpha peaked just after the target crossed the middle of the field of view, and when the handoff was complete, theta peaked in the receiving hemisphere as if to say, “I got it.”
And in trials where the target never crossed the middle of the field of view, these handoff dynamics were not apparent in the measurements.
The study shows that the brain is not simply tracking objects in one hemisphere and then just picking them up anew when they enter the field of view of the other hemisphere.
“These results suggest there are active mechanisms that transfer information between cerebral hemispheres,” the authors wrote. “The brain seems to anticipate the transfer and acknowledge its completion.”
But they also note, based on other studies, that the system of interhemispheric coordination can sometimes appear to break down in certain neurological conditions including schizophrenia, autism, depression, dyslexia, and multiple sclerosis. The new study may lend insight into the specific dynamics needed for it to succeed.
In addition to Broschard, Roy, and Miller, the paper’s other authors are Scott Brincat and Meredith Mahnke.
Funding for the study came from the Office of Naval Research, the National Eye Institute of the National Institutes of Health, The Freedom Together Foundation, and The Picower Institute for Learning and Memory.
Fair Use Protects Everyone—Even the Disney Corporation
Jimmy Kimmel has been in the news a lot recently, which means the ongoing lawsuit against him by perennial late-night punching bag/convicted fraudster/former congressman George Santos flew under the radar. But what happened in that case is an essential illustration of the limits of both copyright law and the “fine print” terms of service on websites and apps.
What happened was this: Kimmel and his staff saw that Santos was on Cameo, which allows people to purchase short videos from various public figures with requested language. Usually it’s something like “happy birthday” or “happy retirement.” In the case of Kimmel and his writers, they set out to see if there was anything they couldn’t get Santos to say on Cameo. For this to work, they obviously didn’t disclose that it was Jimmy Kimmel Live! asking for the videos.
Santos did not like the segment, which aired clips of these videos, called “Will Santos Say It?”. He sued Kimmel, ABC, and ABC’s parent company, Disney. He alleged both copyright infringement and breach of contract—the contract in this case being Cameo’s terms of service. He lost on all counts, twice: his case was dismissed at the district court level, and then that dismissal was upheld by an appeals court.
On the copyright claim, Kimmel and Disney argued and won on the grounds of fair use. The court cited precedent that fair use excuses what might be strictly seen as infringement if such a finding would “stifle the very creativity” that copyright is meant to promote. In this case, the use of the videos was part of the ongoing commentary by Jimmy Kimmel Live! around whether there was anything Santos wouldn’t say for money. Santos tried to argue that since this was their purpose from the outset, the use wasn’t transformative. Which... isn’t how it works. Santos’ purpose was, presumably, to fulfill a request sent through the app. The show’s purpose was to collect enough examples of a behavior to show a pattern and comment on it.
Santos tried to say that their not disclosing what the reason was invalidated the fair use argument because it was “deceptive.” But the court found that the record didn’t show that the deception was designed to replace the market for Santos’s Cameos. It bears repeating: commenting on the quality of a product or the person making it is not legally actionable interference with a business. If someone tells you that a movie, book, or, yes, Cameo isn’t worth anything because of its ubiquity or quality and shows you examples, that’s not a deceptive business practice. In fact, undercover quality checks and reviews are fairly standard practices! Is this a funnier and more entertaining example than a restaurant review? Yes. That doesn’t make it unprotected by fair use.
It’s nice to have this case as a reminder that, despite everything, the major studios often argue, fair use protects everyone, including them. Don’t hold your breath on them remembering this the next time someone tries to make a YouTube review of a Hollywood movie using clips.
Another claim from this case that is less obvious but just as important involves the Cameo terms of service. We often see contracts being used to restrict people’s fair use rights. Cameo offers different kinds of videos for purchase. The most well-known comes with a personal use license, the “happy birthdays,” and so on. They also offer a “commercial” use license, presumably if you want to use the videos to generate revenue, like you do with an ad or paid endorsement. However, in this case, the court found that the terms of service are a contract between a customer and Cameo, not between the customer and the video maker. Cameo’s terms of service explicitly lay out when their terms apply to the person selling a video, and they don’t create a situation where Santos can use those terms to sue Jimmy Kimmel Live! According to the court, the terms don’t even imply a shared understanding and contract between the two parties.
It's so rare to find a situation where the wall of text that most terms of service consist of actually helps protect free expression; it’s a pleasant surprise to see it here.
In general, we at EFF hate it when these kinds of contracts—you know the ones, where you hit accept after scrolling for ages just so you can use the app—are used to constrain users’ rights. Fair use is supposed to protect us all from overly strict interpretations of copyright law, but abusive terms of service can erode those rights. We’ll keep fighting for those rights and the people who use them, even if the one exercising fair use is Disney.
