Scientists at MIT and elsewhere have discovered extremely rare remnants of “proto Earth,” which formed about 4.5 billion years ago, before a colossal collision irreversibly altered the primitive planet’s composition and produced the Earth as we know today. Their findings, reported today in the journal Nature Geosciences, will help scientists piece together the primordial starting ingredients that forged the early Earth and the rest of the solar system.

Billions of years ago, the early solar system was a swirling disk of gas and dust that eventually clumped and accumulated to form the earliest meteorites, which in turn merged to form the proto Earth and its neighboring planets.

In this earliest phase, Earth was likely rocky and bubbling with lava. Then, less than 100 million years later, a Mars-sized meteorite slammed into the infant planet in a singular “giant impact” event that completely scrambled and melted the planet’s interior, effectively resetting its chemistry. Whatever original material the proto Earth was made from was thought to have been altogether transformed.

But the MIT team’s findings suggest otherwise. The researchers have identified a chemical signature in ancient rocks that is unique from most other materials found in the Earth today. The signature is in the form of a subtle imbalance in potassium isotopes discovered in samples of very old and very deep rocks. The team determined that the potassium imbalance could not have been produced by any previous large impacts or geological processes occurring in the Earth presently.

The most likely explanation for the samples’ chemical composition is that they must be leftover material from the proto Earth that somehow remained unchanged, even as most of the early planet was impacted and transformed.

“This is maybe the first direct evidence that we’ve preserved the proto Earth materials,” says Nicole Nie, the Paul M. Cook Career Development Assistant Professor of Earth and Planetary Sciences at MIT. “We see a piece of the very ancient Earth, even before the giant impact. This is amazing because we would expect this very early signature to be slowly erased through Earth’s evolution.”

The study’s other authors include Da Wang of Chengdu University of Technology in China, Steven Shirey and Richard Carlson of the Carnegie Institution for Science in Washington, Bradley Peters of ETH Zürich in Switzerland, and James Day of Scripps Institution of Oceanography in California.

A curious anomaly

In 2023, Nie and her colleagues analyzed many of the major meteorites that have been collected from sites around the world and carefully studied. Before impacting the Earth, these meteorites likely formed at various times and locations throughout the solar system, and therefore represent the solar system’s changing conditions over time. When the researchers compared the chemical compositions of these meteorite samples to Earth, they identified among them a “potassium isotopic anomaly.”

Isotopes are slightly different versions of an element that have the same number of protons but a different number of neutrons. The element potassium can exist in one of three naturally-occurring isotopes, with mass numbers (protons plus neutrons) of 39, 40, and 41, respectively. Wherever potassium has been found on Earth, it exists in a characteristic combination of isotopes, with potassium-39 and potassium-41 being overwhelmingly dominant. Potassium-40 is present, but at a vanishingly small percentage in comparison.

Nie and her colleagues discovered that the meteorites they studied showed balances of potassium isotopes that were different from most materials on Earth. This potassium anomaly suggested that any material that exhibits a similar anomaly likely predates Earth’s present composition. In other words, any potassium imbalance would be a strong sign of material from the proto Earth, before the giant impact reset the planet’s chemical composition.

“In that work, we found that different meteorites have different potassium isotopic signatures, and that means potassium can be used as a tracer of Earth’s building blocks,” Nie explains.

“Built different”

In the current study, the team looked for signs of potassium anomalies not in meteorites, but within the Earth. Their samples include rocks, in powder form, from Greenland and Canada, where some of the oldest preserved rocks are found. They also analyzed lava deposits collected from Hawaii, where volcanoes have brought up some of the Earth’s earliest, deepest materials from the mantle (the planet’s thickest layer of rock that separates the crust from the core).

“If this potassium signature is preserved, we would want to look for it in deep time and deep Earth,” Nie says.

The team first dissolved the various powder samples in acid, then carefully isolated any potassium from the rest of the sample and used a special mass spectrometer to measure the ratio of each of potassium’s three isotopes. Remarkably, they identified in the samples an isotopic signature that was different from what’s been found in most materials on Earth.

Specifically, they identified a deficit in the potassium-40 isotope. In most materials on Earth, this isotope is already an insignificant fraction compared to potassium’s other two isotopes. But the researchers were able to discern that their samples contained an even smaller percentage of potassium-40. Detecting this tiny deficit is like spotting a single grain of brown sand in a bucket rather than a scoop full of of yellow sand.

The team found that, indeed, the samples exhibited the potassium-40 deficit, showing that the materials “were built different,” says Nie, compared to most of what we see on Earth today.

But could the samples be rare remnants of the proto Earth? To answer this, the researchers assumed that this might be the case. They reasoned that if the proto Earth were originally made from such potassium-40-deficient materials, then most of this material would have undergone chemical changes — from the giant impact and subsequent, smaller meteorite impacts — that ultimately resulted in the materials with more potassium-40 that we see today. 

The team used compositional data from every known meteorite and carried out simulations of how the samples’ potassium-40 deficit would change following impacts by these meteorites and by the giant impact. They also simulated geological processes that the Earth experienced over time, such as the heating and mixing of the mantle. In the end, their simulations produced a composition with a slightly higher fraction of potassium-40 compared to the samples from Canada, Greenland, and Hawaii. More importantly, the simulated compositions matched those of most modern-day materials.

The work suggests that materials with a potassium-40 deficit are likely leftover original material from the proto Earth.

Curiously, the samples’ signature isn’t a precise match with any other meteorite in geologists’ collections. While the meteorites in the team’s previous work showed potassium anomalies, they aren’t exactly the deficit seen in the proto Earth samples. This means that whatever meteorites and materials originally formed the proto Earth have yet to be discovered.

“Scientists have been trying to understand Earth’s original chemical composition by combining the compositions of different groups of meteorites,” Nie says. “But our study shows that the current meteorite inventory is not complete, and there is much more to learn about where our planet came from.”

In a letter sent to Microsoft at the end of last month, EFF and five other civil society organizations—Access Now, Amnesty International, Human Rights Watch, Fight for the Future, and 7amleh—called on the company to cease any further involvement in providing AI and cloud computing technologies for use in Israel’s ongoing genocide against Palestinians in the Gaza Strip.

EFF also sent updated letters to Google and Amazon renewing our calls for each company to respond to the serious concerns we raised with each of them last year about how they are fulfilling their respective human rights promises to the public. Neither Google nor Amazon has responded substantively. Amazon failed to even acknowledge our request, much less provide any transparency to the public. 

Microsoft Takes a Positive Step Against Surveillance

On September 25, Microsoft’s Vice Chair & President reported that the company had “ceased and disabled a set of services” provided to a unit within the Israel Ministry of Defense. The announcement followed an internal review at the company after The Guardian reported on August 6 that the IDF is using Azure for the storage of data files of phone calls obtained through broad or mass surveillance of civilians in Gaza and the West Bank.

This investigation by The Guardian, +972 Magazine, and Local Call also revealed the extent to which Israel’s military intelligence unit in question, Unit 8200, has used Microsoft’s Azure cloud infrastructure and AI technologies to process intercepted communications and power AI-driven targeting systems against Palestinians in Gaza and the West Bank—potentially facilitating war crimes and acts of genocide.

Microsoft’s actions are a positive step, and we urge its competitors Google and Amazon to, at the very least, do the same, rather than continuing to support and facilitate mass surveillance of Palestinians in Gaza and the West Bank.  

The Next Steps

But this must be the starting point, and not the end. Our joint letter therefore calls on Microsoft to provide clarity around:

1. What further steps Microsoft will take to suspend its business with the Israeli military and other government bodies where there is evidence indicating that business is contributing to grave human rights abuses and international crimes.
2. Whether Microsoft will commit to publishing the review findings in full, including the scope of the investigation, the specific entities and services under review, and measures Microsoft will take to address adverse human rights impacts related to its business with the Israeli military and other government bodies.
3. What steps Microsoft has taken to ensure that its current formal review thoroughly investigates the use of its technologies by the Israeli authorities, in light of the fact that the same law firm carried out the previous review and concluded that there was no evidence of use of Microsoft’s Azure and AI technologies to target or harm people in Gaza.
4. Whether Microsoft will conduct an additional human rights review, or incorporate a human rights lens to the current review.
5. Whether Microsoft has applied any limited access restrictions to its AI technologies used by the IDF and Israeli government to commit genocide and other international crimes. 
6. Whether Microsoft will evaluate the “high-impact and higher-risk uses” of its evolving AI technology deployed in conflict zones.
7. How Microsoft is planning to provide effective remedy, including reparations, to Palestinians affected by any contributions by the company to violations of human rights by Israel.

Microsoft’s announcement of an internal review and the suspension of some of its services is long overdue and much needed in addressing its potential complicity in human rights abuses. But it must not end here, and Microsoft should not be the only major technology company taking such action.  

EFF, Access Now, Amnesty International, Human Rights Watch, Fight for the Future, and 7amleh provided a deadline of October 10 for Microsoft to respond to the questions outlined in the letter. However, Microsoft is expected to send its written response by the end of the month, and we will publish the response once received.

Two years ago, Americans anxious about the forthcoming 2024 presidential election were considering the malevolent force of an election influencer: artificial intelligence. Over the past several years, we have seen plenty of warning signs from elections worldwide demonstrating how AI can be used to propagate misinformation and alter the political landscape, whether by trolls on social media, foreign influencers, or even a street magician. AI is poised to play a more volatile role than ever before in America’s next federal election in 2026. We can already see how different groups of political actors are approaching AI. Professional campaigners are using AI to accelerate the traditional tactics of electioneering; organizers are using it to reinvent how movements are built; and citizens are using it both to express themselves and amplify their side’s messaging. Because there are so few rules, and so little prospect of regulatory action, around AI’s role in politics, there is no oversight of these activities, and no safeguards against the dramatic potential impacts for our democracy...

For decades, synthetic biologists have been developing gene circuits that can be transferred into cells for applications such as reprogramming a stem cell into a neuron or generating a protein that could help treat a disease such as fragile X syndrome.

These gene circuits are typically delivered into cells by carriers such as nonpathogenic viruses. However, it has been difficult to ensure that these cells end up producing the correct amount of the protein encoded by the synthetic gene.

To overcome that obstacle, MIT engineers have designed a new control mechanism that allows them to establish a desired protein level, or set point, for any gene circuit. This approach also allows them to edit the set point after the circuit is delivered.

“This is a really stable and multifunctional tool. The tool is very modular, so there are a lot of transgenes you could control with this system,” says Katie Galloway, an assistant professor in Chemical Engineering at MIT and the senior author of the new study.

Using this strategy, the researchers showed that they could induce cells to generate consistent levels of target proteins. In one application that they demonstrated, they converted mouse embryonic fibroblasts to motor neurons by delivering high levels of a gene that promotes that conversion.

MIT graduate student Sneha Kabaria is the lead author of the paper, which appears today in Nature Biotechnology. Other authors include Yunbeen Bae ’24; MIT graduate students Mary Ehmann, Brittany Lende-Dorn, Emma Peterman, and Kasey Love; Adam Beitz PhD ’25; and former MIT postdoc Deon Ploessl.

Dialing up gene expression

Synthetic gene circuits are engineered to include not only the gene of interest, but also a promoter region. At this site, transcription factors and other regulators can bind, turning on the expression of the synthetic gene.

However, it’s not always possible to get all of the cells in a population to express the desired gene at a uniform level. One reason for that is that some cells may take up just one copy of the circuit, while others receive many more. Additionally, cells have natural variation in how much protein they produce.

That has made reprogramming cells challenging because it’s difficult to ensure that every cell in a population of skin cells, for example, will produce enough of the necessary transcription factors to successfully transition into a new cell identity, such as a neuron or induced pluripotent stem cell.

In the new paper, the researchers devised a way to control gene expression levels by changing the distance between the synthetic gene and its promoter. They found that when there was a longer DNA “spacer” between the promoter region and the gene, the gene would be expressed at a lower level. That extra distance, they showed, makes it less likely that transcription factors bound to the promoter will effectively turn on gene transcription.

Then, to create set points that could be edited, the researchers incorporated sites within the spacer that can be excised by an enzyme called Cre recombinase. As parts of the spacer are cut out, it helps bring the transcription factors closer to the gene of interest, which turns up gene expression.

The researchers showed they could create spacers with multiple excision points, each targeted by different recombinases. This allowed them to create a system called DIAL, that they could use to establish “high,” “med,” “low” and “off” set points for gene expression.

After the DNA segment carrying the gene and its promoter is delivered into cells, recombinases can be added to the cells, allowing the set point to be edited at any time.

The researchers demonstrated their system in mouse and human cells by delivering the gene for different fluorescent proteins and functional genes, and showed that they could get uniform expression across the a population of cells at the target level.

“We achieved uniform and stable control. This is very exciting for us because lack of uniform, stable control has been one of the things that's been limiting our ability to build reliable systems in synthetic biology. When there are too many variables that affect your system, and then you add in normal biological variation, it’s very hard to build stable systems,” Galloway says.

Reprogramming cells

To demonstrate potential applications of the DIAL system, the researchers then used it to deliver different levels of the gene HRasG12V to mouse embryonic fibroblasts. This HRas variant has previously been shown to increase the rate of conversion of fibroblasts to neurons. The MIT team found that in cells that received a higher dose of the gene, a larger percentage of them were able to successfully transform into neurons.

Using this system, researchers now hope to perform more systematic studies of different transcription factors that can induce cells to transition to different cell types. Such studies could reveal how different levels of those factors affect the success rate, and whether changing the transcription factors levels might alter the cell type that is generated.

In ongoing work, the researchers have shown that DIAL can be combined with a system they previously developed, known as ComMAND, that uses a feedforward loop to help prevent cells from overexpressing a therapeutic gene.

Using these systems together, it could be possible to tailor gene therapies to produce specific, consistent protein levels in the target cells of individual patients, the researchers say.

“This is something we’re excited about because both DIAL and ComMAND are highly modular, so you could not only have a well-controlled gene therapy that’s somewhat general for a population, but you could, in theory, tailor it for any given person or any given cell type,” Galloway says.

The research was funded, in part, by the National Institute of General Medical Sciences, the National Science Foundation, and the Institute for Collaborative Biotechnologies.

Online surveillance is everywhere—and understanding how you’re being tracked, and how to fight back, is more important than ever. That’s why EFF partnered with Women In Security and Privacy (WISP) for our annual Global Members’ Speakeasy, where we tackled online behavioral tracking and the massive data broker industry that profits from your personal information. 

Our live panel featured Rory Mir (EFF Associate Director of Community Organizing), Lena Cohen (EFF Staff Technologist), Mitch Stoltz (EFF IP Litigation Director) and Yael Grauer, Program Manager at Consumer Reports. Together, they unpacked how we arrived at a point where a handful of major tech companies dictate so much of our digital rights, how these monopolies erode privacy, and what real-world consequences come from constant data collection—and most importantly, what you can do to fight back. 

Members also joined in for a lively Q&A, exploring practical steps to opt out of some of this data collection, discussing the efficacy of privacy laws like the California Consumer Privacy Act (CCPA), and sharing tools and tactics to reclaim control over their data. 

We're always excited to find new ways to connect with our supporters and spotlight the critical work that their donations make possible. And because we want everyone to learn from these conversations, you can now watch the full conversation on YouTube or the Internet Archive:

Austin, Texas is a major tech hub with a population that’s engaged in advocacy and paying attention. Since 1991, EFF-Austin an independent nonprofit civil liberties organization, has been the proverbial beacon alerting those in central Texas to the possibilities and implications of modern technology. It is also an active member of the Electronic Frontier Alliance (EFA). On a recent visit to Texas, I got the chance to speak with Kevin Welch, President of EFF-Austin, about the organization, its work, and what lies ahead for them:

How did EFF-Austin get started, and can you share how it got its name?

EFF-Austin is concerned with emerging frontiers where technology meets society. We are a group of visionary technologists, legal professionals, academics, political activists, and concerned citizens who work to protect digital rights and educate the public about emerging technologies and their implications. Similar to our namesake, the national Electronic Frontier Foundation (EFF), “the dominion we defend is the vast wealth of digital information, innovation, and technology that resides online.” EFF-Austin was originally formed in 1991 with the intention that it would become the first chapter of the national Electronic Frontier Foundation. However, EFF decided not to become a chapters organization, and EFF-Austin became a separately-incorporated, independent nonprofit organization focusing on cyber liberties, digital rights, and emerging technologies.

What's the mission of EFF-Austin and what do you promote?

EFF-Austin advocates for establishment and protection of digital rights and defense of the wealth of digital information, innovation, and technology. We promote the right of all citizens to communicate and share information without unreasonable constraint. We also advocate for the fundamental right to explore, tinker, create, and innovate along the frontier of emerging technologies.

EFF-Austin has been involved in a number of initiatives and causes over the past several years, including legislative advocacy. Can you share a few of them?

We were one of the earliest local organizations that began to call out the Austin City Council over their use of automated license plate readers (ALPRs). After several years of fighting, EFF-Austin was proud to join the No ALPRs coalition as a founding member with over thirty local and state activist groups. Through our efforts, Austin decided not to renew our ALPR pilot project, becoming one of the only cities in America to reject ALPRs. Building on this success, the coalition is broadening its scope to call out other uses of surveillance in Austin, like proposed contracts for park surveillance from Liveview Technologies, as well as data privacy abuses more generally, such as the potential partnership with Valkyrie AI to non-consensually provide citizen data for model training and research purposes without sufficient oversight or guardrails. In support of these initiatives, EFF-Austin also partnered with the Austin Technology Commission to propose much stricter oversight and transparency rules around how the city of Austin engages in contracts with third party technology vendors.

EFF-Austin has also provided expert testimony on a number of major technology bills at the Texas Legislature that have since become law, including the Texas Data Privacy And Security Act (TDPSA) and the Texas Responsible AI Governance Act (TRAIGA).

How can someone local to central Texas get involved?

We conduct monthly meetups with a variety of speakers, usually the second Tuesday of each month at 7:00pm at Capital Factory (701 Brazos St, Austin, TX 78701) in downtown Austin. These meetups can range from technology and legal explainers to digital security trainings, from digital arts profiles to shining a spotlight on surveillance. In addition, we have various one-off events, often in partnership with other local nonprofits and civic institutions, including our fellow EFA member Open Austin. We also have annual holiday parties and SXSW gatherings that are free and open to the public. We don't currently have memberships, so any and all are welcome.

While EFF-Austin events are popular and well-attended, and our impact on local technology policy is quite impressive for such a small nonprofit, we have no significant sustained funding beyond occasional outreach to our community. Any local nonprofits, activist organizations, academic initiatives, or technology companies who find themselves aligned with our cause and would like to fund our efforts are encouraged to reach out. We also always welcome the assistance of those who wish to volunteer their technical, organizational, or legal skills to our cause. In addition to emailing us at info@effaustin.org, follow us on Mastodon, Bluesky, Twitter, Facebook, Instagram, or Meetup, and visit us at our website at https://effaustin.org.

The Massachusetts Institute of Technology Investment Management Company (MITIMCo) announced today that MIT’s unitized pool of endowment and other MIT funds generated an investment return of 14.8 percent during the fiscal year ending June 30, 2025, as measured using valuations received within one month of fiscal year end. At the end of the fiscal year, MIT’s endowment funds totaled $27.4 billion, excluding pledges. Over the 10 years ending June 30, 2025, MIT generated an annualized return of 10.7 percent.

The endowment is the bedrock of MIT’s finances, made possible by gifts from alumni and friends for more than a century. The use of the endowment is governed by a state law that requires MIT to maintain each endowed gift as a permanent fund, preserve its purchasing power, and spend it as directed by its original donor. Most of the endowment’s funds are restricted and must be used for a specific purpose. MIT uses the bulk of the income these endowed gifts generate to support financial aid, research, and education.

The endowment supports 50 percent of undergraduate tuition, helping to enable the Institute’s need-blind undergraduate admissions policy, which ensures that an MIT education is accessible to all qualified candidates regardless of financial resources. MIT works closely with all families of undergraduates who qualify for financial aid to develop an individual affordability plan tailored to their financial circumstances. In 2024-25, the average need-based MIT undergraduate scholarship was $62,127. Fifty-seven percent of MIT undergraduates received need-based financial aid, and 39 percent of MIT undergraduate students received scholarship funding from MIT and other sources sufficient to cover the total cost of tuition.

Effective in fiscal 2026, MIT enhanced undergraduate financial aid, ensuring that all families with incomes below $200,000 and typical assets have tuition fully covered by scholarships, and that families with incomes below $100,000 and typical assets pay nothing at all for their students’ MIT education. Eighty-eight percent of seniors who graduated in academic year 2025 graduated with no debt.

MITIMCo is a unit of MIT, created to manage and oversee the investment of the Institute’s endowment, retirement, and operating funds.

MIT’s Report of the Treasurer for fiscal year 2025, which details the Institute’s annual financial performance, was made available publicly today.

AI agents are now hacking computers. They’re getting better at all phases of cyberattacks, faster than most of us expected. They can chain together different aspects of a cyber operation, and hack autonomously, at computer speeds and scale. This is going to change everything.
