Knowledge production doesn’t happen in a vacuum. Every great scientific breakthrough is built on prior work, and an ongoing exchange with peers in the field. That’s why we need to address the threat of major publishers and platforms having an improper influence on how scientific knowledge is accessed—or outright suppressed.

In the digital age, the collaborative and often community-governed effort of scholarly research has gone global and unlocked unprecedented potential to improve our understanding and quality of life. That is, if we let it. Publishers continue to monopolize access to life-saving research and increase the burden on researchers through article processing charges and a pyramid of volunteer labor. This exploitation makes a mockery of open inquiry and the denial of access as a serious human rights issue.

While alternatives like Diamond Open Access are promising, crashing through publishing gatekeepers isn’t enough. Large intermediary platforms are capturing other aspects of the research process—inserting themselves between researchers and between the researchers and these published works—through platformization. 

Funneling scholars into a few major platforms isn’t just annoying, it’s corrosive to privacy and intellectual freedom. Enshittification has come for research infrastructure, turning everyday tools into avenues for surveillance. Most professors are now worried their research is being scrutinized by academic bossware, forcing them to worry about arbitrary metrics which don’t always reflect research quality. While playing this numbers game, a growing threat of surveillance in scholarly publishing gives these measures a menacing tilt, chilling the publication and access of targeted research areas. These risks spike in the midst of governmental campaigns to muzzle scientific knowledge, buttressed by a scourge of platform censorship on corporate social media.

The only antidote to this ‘platformization’ is Open Science and decentralization. Infrastructure we rely on must be built in the open and on interoperable standards, and hostile to corporate (or governmental) takeovers. Universities and the science community are well situated to lead this fight. As we’ve seen in EFF’s TOR University Challenge, promoting access to knowledge and public interest infrastructure is aligned with the core values of higher education. 

Using social media as an example, universities have a strong interest in promoting the work being done at their campuses far and wide. This is where traditional platforms fall short: algorithms typically prioritizing paid content, downrank off-site links, and prioritize sensational claims to drive engagement. When users are free from enshittification and can themselves control the  platform’s algorithms, as they can on platforms like Bluesky, scientists get more engagement and find interactions are more useful. 

Institutions play a pivotal role in encouraging the adoption of these alternatives, ranging from leveraging existing IT support to assist with account use and verification, all the way to shouldering some of the hosting with Mastodon instances and/or Bluesky PDS for official accounts. This support is good for the research, good for the university, and makes our systems of science more resilient to attacks on science and the instability of digital monocultures.

This subtle influence of intermediaries can also appear in other tools relied on by researchers, while there are a number of open alternatives and interoperable tools developed for everything from citation management, data hosting to online chat among collaborators. Individual scholars and research teams can implement these tools today, but real change depends on institutions investing in tech that puts community before shareholders.

When infrastructure is too centralized, gatekeepers gain new powers to capture, enshittify, and censor. The result is a system that becomes less useful, less stable, and with more costs put on access. Science thrives on sharing and access equity, and its future depends on a global and democratic revolt against predatory centralized platforms.

EFF is proud to celebrate Open Access Week.

Today, EFF joined a coalition of civil society organizations in urging UN Member States not to sign the UN Convention Against Cybercrime. For those that move forward despite these warnings, we urge them to take immediate and concrete steps to limit the human rights harms this Convention will unleash. These harms are likely to be severe and will be extremely difficult to prevent in practice.

The Convention obligates states to establish broad electronic surveillance powers to investigate and cooperate on a wide range of crimes—including those unrelated to information and communication systems—without adequate human rights safeguards. It requires governments to collect, obtain, preserve, and share electronic evidence with foreign authorities for any “serious crime”—defined as an offense punishable under domestic law by at least four years’ imprisonment (or a higher penalty).

In many countries, merely speaking freely; expressing a nonconforming sexual orientation or gender identity; or protesting peacefully can constitute a serious criminal offense per the definition of the convention. People have faced lengthy prison terms, or even more severe acts like torture, for criticizing their governments on social media, raising a rainbow flag, or criticizing a monarch. 

In today’s digital era, nearly every message or call generates granular metadata—revealing who communicates with whom, when, and from where—that routinely traverses national borders through global networks. The UN cybercrime convention, as currently written, risks enabling states to leverage its expansive cross-border data-access and cooperation mechanisms to obtain such information for political surveillance—abusing the Convention’s mechanisms to monitor critics, pressure their families, and target marginalized communities abroad.

As abusive governments increasingly rely on questionable tactics to extend their reach beyond their borders—targeting dissidents, activists, and journalists worldwide—the UN Cybercrime Convention risks becoming a vehicle for globalizing repression, enabling an unprecedented multilateral infrastructure for digital surveillance that allows states to access and exchange data across borders in ways that make political monitoring and targeting difficult to detect or challenge.

EFF has long sounded the alarm over the UN Cybercrime Treaty’s sweeping powers of cross-border cooperation and its alarming lack of human-rights safeguards. As the Convention opens for signature on October 25–26, 2025 in Hanoi, Vietnam—a country repeatedly condemned by international rights groups for jailing critics and suppressing online speech—the stakes for global digital freedom have never been higher.

The Convention’s many flaws cannot easily be mitigated because it fundamentally lacks a mechanism for suspending states that systematically fail to respect human rights or the rule of law. States must refuse to sign or ratify the Convention.

How can you use science to build a better gingerbread house?

That was something Miranda Schwacke spent a lot of time thinking about. The MIT graduate student in the Department of Materials Science and Engineering (DMSE) is part of Kitchen Matters, a group of grad students who use food and kitchen tools to explain scientific concepts through short videos and outreach events. Past topics included why chocolate “seizes,” or becomes difficult to work with when melting (spoiler: water gets in), and how to make isomalt, the sugar glass that stunt performers jump through in action movies.

Two years ago, when the group was making a video on how to build a structurally sound gingerbread house, Schwacke scoured cookbooks for a variable that would produce the most dramatic difference in the cookies.

“I was reading about what determines the texture of cookies, and then tried several recipes in my kitchen until I got two gingerbread recipes that I was happy with,” Schwacke says.

She focused on butter, which contains water that turns to steam at high baking temperatures, creating air pockets in cookies. Schwacke predicted that decreasing the amount of butter would yield denser gingerbread, strong enough to hold together as a house.

“This hypothesis is an example of how changing the structure can influence the properties and performance of material,” Schwacke said in the eight-minute video.

That same curiosity about materials properties and performance drives her research on the high energy cost of computing, especially for artificial intelligence. Schwacke develops new materials and devices for neuromorphic computing, which mimics the brain by processing and storing information in the same place. She studies electrochemical ionic synapses — tiny devices that can be “tuned” to adjust conductivity, much like neurons strengthening or weakening connections in the brain.

“If you look at AI in particular — to train these really large models — that consumes a lot of energy. And if you compare that to the amount of energy that we consume as humans when we’re learning things, the brain consumes a lot less energy,” Schwacke says. “That’s what led to this idea to find more brain-inspired, energy-efficient ways of doing AI.”

Her advisor, Bilge Yildiz, underscores the point: One reason the brain is so efficient is that data doesn’t need to be moved back and forth.

“In the brain, the connections between our neurons, called synapses, are where we process information. Signal transmission is there. It is processed, programmed, and also stored in the same place,” says Yildiz, the Breene M. Kerr (1951) Professor in the Department of Nuclear Science and Engineering and DMSE. Schwacke’s devices aim to replicate that efficiency.

Scientific roots

The daughter of a marine biologist mom and an electrical engineer dad, Schwacke was immersed in science from a young age. Science was “always a part of how I understood the world.”

“I was obsessed with dinosaurs. I wanted to be a paleontologist when I grew up,” she says. But her interests broadened. At her middle school in Charleston, South Carolina, she joined a FIRST Lego League robotics competition, building robots to complete tasks like pushing or pulling objects. “My parents, my dad especially, got very involved in the school team and helping us design and build our little robot for the competition.”

Her mother, meanwhile, studied how dolphin populations are affected by pollution for the National Oceanic and Atmospheric Administration. That had a lasting impact.

“That was an example of how science can be used to understand the world, and also to figure out how we can improve the world,” Schwacke says. “And that’s what I’ve always wanted to do with science.”

Her interest in materials science came later, in her high school magnet program. There, she was introduced to the interdisciplinary subject, a blend of physics, chemistry, and engineering that studies the structure and properties of materials and uses that knowledge to design new ones.

“I always liked that it goes from this very basic science, where we’re studying how atoms are ordering, all the way up to these solid materials that we interact with in our everyday lives — and how that gives them their properties that we can see and play with,” Schwacke says.

As a senior, she participated in a research program with a thesis project on dye-sensitized solar cells, a low-cost, lightweight solar technology that uses dye molecules to absorb light and generate electricity.

“What drove me was really understanding, this is how we go from light to energy that we can use — and also seeing how this could help us with having more renewable energy sources,” Schwacke says.

After high school, she headed across the country to Caltech. “I wanted to try a totally new place,” she says, where she studied materials science, including nanostructured materials thousands of times thinner than a human hair. She focused on materials properties and microstructure — the tiny internal structure that governs how materials behave — which led her to electrochemical systems like batteries and fuel cells.

AI energy challenge

At MIT, she continued exploring energy technologies. She met Yildiz during a Zoom meeting in her first year of graduate school, in fall 2020, when the campus was still operating under strict Covid-19 protocols. Yildiz’s lab studies how charged atoms, or ions, move through materials in technologies like fuel cells, batteries, and electrolyzers.

The lab’s research into brain-inspired computing fired Schwacke’s imagination, but she was equally drawn to Yildiz’s way of talking about science.

“It wasn’t based on jargon and emphasized a very basic understanding of what was going on — that ions are going here, and electrons are going here — to understand fundamentally what’s happening in the system,” Schwacke says.

That mindset shaped her approach to research. Her early projects focused on the properties these devices need to work well — fast operation, low energy use, and compatibility with semiconductor technology — and on using magnesium ions instead of hydrogen, which can escape into the environment and make devices unstable.

Her current project, the focus of her PhD thesis, centers on understanding how the insertion of magnesium ions into tungsten oxide, a metal oxide whose electrical properties can be precisely tuned, changes its electrical resistance. In these devices, tungsten oxide serves as a channel layer, where resistance controls signal strength, much like synapses regulate signals in the brain.

“I am trying to understand exactly how these devices change the channel conductance,” Schwacke says.

Schwacke’s research was recognized with a MathWorks Fellowship from the School of Engineering in 2023 and 2024. The fellowship supports graduate students who leverage tools like MATLAB or Simulink in their work; Schwacke applied MATLAB for critical data analysis and visualization.

Yildiz describes Schwacke’s research as a novel step toward solving one of AI’s biggest challenges.

“This is electrochemistry for brain-inspired computing,” Yildiz says. “It’s a new context for electrochemistry, but also with an energy implication, because the energy consumption of computing is unsustainably increasing. We have to find new ways of doing computing with much lower energy, and this is one way that can help us move in that direction.”

Like any pioneering work, it comes with challenges, especially in bridging the concepts between electrochemistry and semiconductor physics.

“Our group comes from a solid-state chemistry background, and when we started this work looking into magnesium, no one had used magnesium in these kinds of devices before,” Schwacke says. “So we were looking at the magnesium battery literature for inspiration and different materials and strategies we could use. When I started this, I wasn’t just learning the language and norms for one field — I was trying to learn it for two fields, and also translate between the two.”

She also grapples with a challenge familiar to all scientists: how to make sense of messy data.

“The main challenge is being able to take my data and know that I’m interpreting it in a way that’s correct, and that I understand what it actually means,” Schwacke says.

She overcomes hurdles by collaborating closely with colleagues across fields, including neuroscience and electrical engineering, and sometimes by just making small changes to her experiments and watching what happens next.

Community matters

Schwacke is not just active in the lab. In Kitchen Matters, she and her fellow DMSE grad students set up booths at local events like the Cambridge Science Fair and Steam It Up, an after-school program with hands-on activities for kids.

“We did ‘pHun with Food’ with ‘fun’ spelled with a pH, so we had cabbage juice as a pH indicator,” Schwacke says. “We let the kids test the pH of lemon juice and vinegar and dish soap, and they had a lot of fun mixing the different liquids and seeing all the different colors.”

She has also served as the social chair and treasurer for DMSE’s graduate student group, the Graduate Materials Council. As an undergraduate at Caltech, she led workshops in science and technology for Robogals, a student-run group that encourages young women to pursue careers in science, and assisted students in applying for the school’s Summer Undergraduate Research Fellowships.

For Schwacke, these experiences sharpened her ability to explain science to different audiences, a skill she sees as vital whether she’s presenting at a kids’ fair or at a research conference.

“I always think, where is my audience starting from, and what do I need to explain before I can get into what I’m doing so that it’ll all make sense to them?” she says.

Schwacke sees the ability to communicate as central to building community, which she considers an important part of doing research. “It helps with spreading ideas. It always helps to get a new perspective on what you’re working on,” she says. “I also think it keeps us sane during our PhD.”

Yildiz sees Schwacke’s community involvement as an important part of her resume. “She’s doing all these activities to motivate the broader community to do research, to be interested in science, to pursue science and technology, but that ability will help her also progress in her own research and academic endeavors.”

After her PhD, Schwacke wants to take that ability to communicate with her to academia, where she’d like to inspire the next generation of scientists and engineers. Yildiz has no doubt she’ll thrive.

“I think she’s a perfect fit,” Yildiz says. “She’s brilliant, but brilliance by itself is not enough. She’s persistent, resilient. You really need those on top of that.”

Physicists at MIT have developed a new way to probe inside an atom’s nucleus, using the atom’s own electrons as “messengers” within a molecule.

In a study appearing today in the journal Science, the physicists precisely measured the energy of electrons whizzing around a radium atom that had been paired with a fluoride atom to make a molecule of radium monofluoride. They used the environments within molecules as a sort of microscopic particle collider, which contained the radium atom’s electrons and encouraged them to briefly penetrate the atom’s nucleus.

Typically, experiments to probe the inside of atomic nuclei involve massive, kilometers-long facilities that accelerate beams of electrons to speeds fast enough to collide with and break apart nuclei. The team’s new molecule-based method offers a table-top alternative to directly probe the inside of an atom’s nucleus.

Within molecules of radium monofluoride, the team measured the energies of a radium atom’s electrons as they pinged around inside the molecule. They discerned a slight energy shift and determined that electrons must have briefly penetrated the radium atom’s nucleus and interacted with its contents. As the electrons winged back out, they retained this energy shift, providing a nuclear “message” that could be analyzed to sense the internal structure of the atom’s nucleus.

The team’s method offers a new way to measure the nuclear “magnetic distribution.” In a nucleus, each proton and neutron acts like a small magnet, and they align differently depending on how the nucleus’ protons and neutrons are spread out. The team plans to apply their method to precisely map this property of the radium nucleus for the first time. What they find could help to answer one of the biggest mysteries in cosmology: Why do we see much more matter than antimatter in the universe?

“Our results lay the groundwork for subsequent studies aiming to measure violations of fundamental symmetries at the nuclear level,” says study co-author Ronald Fernando Garcia Ruiz, who is the Thomas A. Franck Associate Professor of Physics at MIT. “This could provide answers to some of the most pressing questions in modern physics.”

The study’s MIT co-authors include Shane Wilkins, Silviu-Marian Udrescu, and Alex Brinson, along with collaborators from multiple institutions including the Collinear Resonance Ionization Spectroscopy Experiment (CRIS) at CERN in Switzerland, where the experiments were performed.

Molecular trap

According to scientists’ best understanding, there must have been almost equal amounts of matter and antimatter when the universe first came into existence. However, the overwhelming majority of what scientists can measure and observe in the universe is made from matter, whose building blocks are the protons and neutrons within atomic nuclei.

This observation is in stark contrast to what our best theory of nature, the Standard Model, predicts, and it is thought that additional sources of fundamental symmetry violation are required to explain the almost complete absence of antimatter in our universe. Such violations could be seen within the nuclei of certain atoms such as radium.

Unlike most atomic nuclei, which are spherical in shape, the radium atom’s nucleus has a more asymmetrical configuration, similar to a pear. Scientists predict that this pear shape could significantly enhance their ability to sense the violation of fundamental symmetries, to the extent that they may be potentially observable.

“The radium nucleus is predicted to be an amplifier of this symmetry breaking, because its nucleus is asymmetric in charge and mass, which is quite unusual,” says Garcia Ruiz, whose group has focused on developing methods to probe radium nuclei for signs of fundamental symmetry violation.

Peering inside the nucleus of a radium atom to investigate fundamental symmetries is an incredibly tricky exercise.

“Radium is naturally radioactive, with a short lifetime and we can currently only produce radium monofluoride molecules in tiny quantities,” says study lead author Shane Wilkins, a former postdoc at MIT. “We therefore need incredibly sensitive techniques to be able measure them.”

The team realized that by placing a radium atom in a molecule, they could contain and amplify the behavior of its electrons.

“When you put this radioactive atom inside of a molecule, the internal electric field that its electrons experience is orders of magnitude larger compared to the fields we can produce and apply in a lab,” explains Silviu-Marian Udrescu PhD ’24, a study co-author. “In a way, the molecule acts like a giant particle collider and gives us a better chance to probe the radium’s nucleus.”

Energy shift

In their new study, the team first paired radium atoms with fluoride atoms to create molecules of radium monofluoride. They found that in this molecule, the radium atom’s electrons were effectively squeezed, increasing the chance for electrons to interact with and briefly penetrate the radium nucleus.

The team then trapped and cooled the molecules and sent them through a system of vacuum chambers, into which they also sent lasers, which interacted with the molecules. In this way the researchers were able to precisely measure the energies of electrons inside each molecule.

When they tallied the energies, they found that the electrons appeared to have a slightly different energy compared to what physicists expect if they did not penetrate the nucleus. Although this energy shift was small — just a millionth of the energy of the laser photon used to excite the molecules — it gave unambiguous evidence of the molecules’ electrons interacting with the protons and neutrons inside the radium nucleus.

“There are many experiments measuring interactions between nuclei and electrons outside the nucleus, and we know what those interactions look like,” Wilkins explains. “When we went to measure these electron energies very precisely, it didn’t quite add up to what we expected assuming they interacted only outside of the nucleus. That told us the difference must be due to electron interactions inside the nucleus.”

“We now have proof that we can sample inside the nucleus,” Garcia Ruiz says. “It’s like being able to measure a battery’s electric field. People can measure its field outside, but to measure inside the battery is far more challenging. And that’s what we can do now.”

Going forward, the team plans to apply the new technique to map the distribution of forces inside the nucleus. Their experiments have so far involved radium nuclei that sit in random orientations inside each molecule at high temperature. Garcia Ruiz and his collaborators would like to be able to cool these molecules and control the orientations of their pear-shaped nuclei such that they can precisely map their contents and hunt for the violation of fundamental symmetries.

“Radium-containing molecules are predicted to be exceptionally sensitive systems in which to search for violations of the fundamental symmetries of nature,” Garcia Ruiz says. “We now have a way to carry out that search.”
