Rising temperatures are slowing early childhood development

10 December 2025 at 05:59
Researchers discovered that unusually high temperatures can hinder early childhood development. Children living in hotter conditions were less likely to reach key learning milestones, especially in reading and basic math skills. Those facing economic hardship or limited resources were hit the hardest. The study underscores how climate change may shape children’s learning long before they reach school age.

Scientists reveal a tiny brain chip that streams thoughts in real time

10 December 2025 at 04:54
BISC is an ultra-thin neural implant that creates a high-bandwidth wireless link between the brain and computers. Its tiny single-chip design packs tens of thousands of electrodes and supports advanced AI models for decoding movement, perception, and intent. Initial clinical work shows it can be inserted through a small opening in the skull and remain stable while capturing detailed neural activity. The technology could reshape treatments for epilepsy, paralysis, and blindness.

This surprising discovery rewrites the Milky Way’s origin story

9 December 2025 at 13:29
New simulations of Milky Way-like galaxies reveal that the strange split between two chemically distinct groups of stars may arise from several very different evolutionary events. Bursts of star formation, shifts in flowing gas, and even streams of metal-poor material from a galaxy’s outskirts can all create this double pattern. The findings challenge the long-held assumption that a major ancient collision caused the split.

Simple supplement mix shows remarkable results in brain cancer

10 December 2025 at 08:56
New research is challenging one of medicine’s oldest assumptions: that cancer must be attacked to be cured. By treating glioblastoma patients with a simple combination of resveratrol and copper, the researchers found dramatic reductions in tumor aggressiveness, cancer biomarkers, immune checkpoints, and stem-cell–related markers—all without side effects. Their approach focuses on “healing” tumors by eliminating harmful cell-free chromatin particles released from dying cancer cells, which normally inflame and worsen the disease. The findings hint at a future where inexpensive nutraceuticals could transform cancer therapy.

James Webb catches a giant helium cloud pouring off a puffy planet

10 December 2025 at 07:10
Astronomers using the James Webb Space Telescope have captured dramatic helium streams pouring off the super-puff exoplanet WASP-107b, revealing a world with an enormously inflated, weakly bound atmosphere under intense stellar heat. The detection of helium, water, and various chemical compounds—alongside the surprising absence of methane—paints a picture of a planet that formed far from its star but later migrated inward, where scorching radiation now strips its gases into space.

Human brains light up for chimp voices in a way no one expected

10 December 2025 at 06:45
Humans don’t just recognize each other’s voices—our brains also light up for the calls of chimpanzees, hinting at ancient communication roots shared with our closest primate relatives. Researchers found a specialized region in the auditory cortex that reacts distinctly to chimp vocalizations, but not to those of bonobos or macaques, revealing an unexpected mix of evolutionary and acoustic influences.

Simple light trick reveals hidden brain pathways in microscopic detail

9 December 2025 at 15:50
Microscopic fibers secretly shape how every organ in the body works, yet they’ve been notoriously hard to study—until now. A new imaging technique called ComSLI reveals hidden fiber orientations in stunning detail using only a rotating LED light and simple microscopy equipment. It works on any tissue slide, from fresh samples to those more than a century old, allowing scientists to uncover microstructural changes in disorders like Alzheimer’s and even explore the architecture of muscle, bone, and blood vessels.

Small root mutation could make crops fertilize themselves

9 December 2025 at 15:39
Scientists discovered a small protein region that determines whether plants reject or welcome nitrogen-fixing bacteria. By tweaking only two amino acids, they converted a defensive receptor into one that supports symbiosis. Early success in barley hints that cereals may eventually be engineered to fix nitrogen on their own. Such crops could dramatically reduce fertilizer use and emissions.

New cosmic lens measurements deepen the Hubble tension mystery

9 December 2025 at 14:26
Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their results match “local” measurements but clash with early-universe estimates, strengthening the mysterious Hubble tension. This mismatch could point to new physics rather than observational error. Researchers now aim to boost precision to solve the puzzle.

Astronomers capture sudden black hole blast firing ultra fast winds

9 December 2025 at 14:02
A sudden X-ray flare from a supermassive black hole in galaxy NGC 3783 triggered ultra-fast winds racing outward at a fifth the speed of light—an event never witnessed before. Using XMM-Newton and XRISM, astronomers caught the blast unfold in real time, revealing how tangled magnetic fields can rapidly “untwist” and hurl matter into space much like an enormous, cosmic-scale version of the Sun’s coronal mass ejections.

Report: Wisconsin schools allocated COVID funds on historic staffing, not recovery

(The Center Square) – Wisconsin schools spent 41% of the $1.49 billion in pandemic recovery federal funding on permanent salaries rather than temporary learning recovery solutions while allocating the funding slowly and without transparency, according to a new report.

Madison couple who fled Venezuela win asylum, but ICE detention continues

A Chicago immigration court judge has granted the asylum request of a Madison couple who U.S. Immigration and Customs Enforcement (ICE) officers arrested during a routine check-in at the agency’s Milwaukee office in October.

Judge Eva Saltzman sided with Dailin Pacheco-Acosta and Diego Ugarte-Arenas on Tuesday afternoon, but the Department of Homeland Security (DHS) – ICE’s parent agency – reserved the right to appeal.

The ruling does not automatically free the couple from ICE custody. 

“It’s not over,” said Ben Crouse, the couple’s Milwaukee-based attorney. 

Ugarte-Arenas remains in the Dodge County jail, which contracts with ICE to hold immigrants facing deportation, and Pacheco-Acosta sits in a county jail in northern Kentucky. A recent Trump administration policy has prevented them from posting bond and continuing their asylum case from Madison, where they settled in 2021 after fleeing Venezuela. 

The couple crossed the U.S.-Mexico border without a visa, but because of a clerical error by Customs and Border Patrol officers they encountered near Eagle Pass, Texas, they did not initially land before an immigration court and were instead able to file for asylum with U.S. Citizenship and Immigration Services upon reaching Wisconsin. The couple refiled for asylum with the immigration court in Chicago after their arrests in October. Neither has a past criminal conviction nor a pending criminal charge.

As they await the next step in their legal battle, the Trump administration is defending the policy that has kept the couple in custody for more than a month, even after a federal judge in California challenged its legality. How higher courts rule will determine whether thousands of immigrants in ICE custody can post bond for the first time in months.

Trump officials seek ‘mandatory detention’

Reversing decades of precedent, DHS announced in July that most immigrants in ICE custody would be ineligible for bond and are instead subject to “mandatory detention.” The Board of Immigration Appeals, a body within the U.S. Department of Justice (DOJ) that sets rules for immigration courts, sided with DHS in September. 

But a Nov. 20 ruling by U.S. Judge Sunshine Sykes of the Central District of California gave the Madison couple and ICE detainees nationwide a moment of optimism. 

Sykes partially ruled on the side of four undocumented immigrants ICE picked up during a June immigration raid in Los Angeles. The four immigrants, represented by attorneys from multiple immigrant rights organizations, had filed a class action lawsuit challenging the rule after they were denied bond. 

But both DHS and DOJ, which oversees immigration court judges, argue Sykes’ decision doesn’t apply to all immigrants in similar positions nationwide. Many immigration court judges, including in Chicago, the court with jurisdiction over most immigrants detained in Wisconsin, have continued to deny bond hearings for immigrants in custody, citing the administration’s reasoning. 

DOJ spokesperson Kathryn Mattingly said department leaders are not instructing immigration judges to specifically reject bond motions.

“Immigration judges are independent adjudicators and decide all matters before them on a case-by-case basis,” Mattingly wrote in a statement to Wisconsin Watch.

Next steps for Madison couple

Crouse, the couple’s attorney, filed motions seeking the Madison couple’s bond before the California ruling. Their motions, even if futile, could help clarify the scope of Sykes’ ruling, he said. 

Crouse and other attorneys are separately testing the last remaining pathway to release: filing “habeas petitions” asking judges to rule on the lawfulness of their clients’ detention. A district court judge in Milwaukee denied a petition for Ugarte-Arenas on Monday, and Pacheco-Acosta is still awaiting a decision from a judge in Kentucky. If Pacheco-Acosta’s petition is successful, she will receive a bond hearing. 

Back in Chicago, Judge Saltzman is preparing a written order outlining her reasoning for granting the couple asylum. DHS signaled plans to challenge her decision before the Board of Immigration appeals. It has 30 days to do so after Saltzman releases her written order. 

Though Crouse called the couple’s case strong — not least because of mounting U.S. military actions in Venezuela —  he noted that recent board decisions siding with DHS mean nothing is assured.

Yes.

State funding of the Wisconsin Department of Natural Resources has been reduced by more than $100 million per biennium in the past 30 years.

A key factor: smaller debt payments.

DNR received $334.3 million in state general purpose revenue in the 1995-97 state budget and $226.2 million in 2025-27.

That’s a reduction of $108.1 million, or 32%.

Between the two periods, debt service dropped from $234.7 million to $103.4 million. 

A Wisconsin Reddit user posted Nov. 22 about the cuts.

A 2023 report on DNR by the nonpartisan Wisconsin Policy Forum said those savings have been used to fund Medicaid, K-12 schools, prisons and tax cuts. Republicans have controlled all or part of the state budget process for all but one cycle since 1995.

The DNR is charged with protecting and enhancing air, land, water, forests, wildlife, fish and plants and provides outdoor recreational activities.

  • Undergraduate students can major in public policy starting in fall 2026.
  • Officials say that it’s the first public policy major in Wisconsin and that it may be the only one in the country focused on teaching students how to engage in civil dialogue and find common ground. 
  • More and more students were interested in undergraduate certificates from the La Follette School of Public Affairs, which caused leaders to investigate whether there would be demand for a major. 
  • Students will learn how to use curiosity to connect with people, as well as how to evaluate the effectiveness of policies.

At a time when American politics are increasingly polarized and partisan, the University of Wisconsin-Madison is launching a new undergraduate major focused on working across those divides to create evidence-based public policy. 

The public policy major, debuting in fall 2026, is the first undergraduate major from the La Follette School of Public Affairs. The Wisconsin Legislature created the school in 1983 to educate future public servants for state and local government. In 2019, after decades of offering only graduate programs, the school added undergraduate certificates — UW-Madison’s version of a minor — in public policy and later in health policy.

Today, they’re among the most popular certificates on campus, said La Follette School Director Susan Webb Yackee. The animosity and gridlock that plague American politics hasn’t discouraged students. In fact, she thinks it’s only made them more interested. 

“This could be a time when our young people are running away from our policy problems, but many of them are running toward them,” Yackee said, noting that she’s seen particular interest in policies about health, environment and climate change. 

With the new major, those young people will have the option to make public policy their primary focus. School leaders say that it’s the first public policy major in Wisconsin and that it may be the only one in the country focused on teaching students how to engage in civil dialogue and find common ground. 

Those are the skills society needs today, Yackee said.

“In a 50-50 state like Wisconsin, in a 50-50 country like the United States, we won’t be able to solve our big public policy problems by simply taking the point of view that one might agree with,” Yackee said. “We will have to work across the political aisle to make real change.”

Yackee spoke to Wisconsin Watch about how she hopes the new program will transform students, campus and the future of policymaking in the United States.  

The following interview has been edited for length and clarity. 

What exactly is public policy, and how is it different from political science?

Public policy is the study of government institutions as well as decision making that affects everyone’s lives. That differs from political science in the sense that we’re interested in not just the politics of how those decisions get made, but also whether public policies that go into effect work or not. Evaluating what works and what doesn’t in existing public policy, as well as predicting what kinds of policies may work and why, is a terrifically important part of our faculty research, as well as the classes that students take….

I’m a political scientist, but most of our faculty at the La Follette School are economists. They’re oftentimes much more focused on … Does that policy work? How is it different than policies in other states? If there’s a policy change, did that change actually match what legislators or practitioners wanted to see happen?

Why did the faculty decide to focus the new curriculum on civil dialogue and finding common ground?

Our mission is evidence-based policymaking, and we quickly identified that to get to our mission, people had to be able to sit down in the same room and talk about it. You have to be able to talk before you can talk about evidence … That was a need we felt we could serve particularly well within our major … That’s also a skill that a lot of our undergraduate students on campus, who might not be public policy majors, could also benefit from. 

For some people, this feels like a sort of dismal time for politics or public policy. What are you hearing from students about why they’re interested in public policy and what kinds of problems they want to solve?

It’s absolutely true that politics and our current public policy atmosphere turns off a lot of people right now. But very interestingly, we’re seeing huge student engagement in public policy on campus …

A lot of UW-Madison students are interested in working in the nonprofit sector. Many nonprofits need to be able to evaluate their programs to see if they work or not … We teach classes in: How would we understand the goals of the program? How would we quantify them? … So the kind of skills-based classes that we teach have a lot of translation into other fields beyond just government service. 

Do you hear students expressing frustration with politicians today? 

I think there’s a lot of frustration with inaction, and I think that’s normal for traditionally aged college students. Is that any different today than it was in the 1970s or the 1950s? They’re impatient for change, and good for them. I am too, and I love their impatience.

“If we can position students with (these) skills … and they can be trained and ready to go when our country arguably needs them more than ever, then we will have done our job as educators,” Susan Webb Yackee says. (Joe Timmerman / Wisconsin Watch)

Let me give you a concrete example of a class I taught … It was for students to do applied policy analysis with real-world clients. This class happened to have three real-world clients, and they were all sitting Wisconsin legislators…

The first day of class was me saying, “Some of you are going to get assigned to work with a Republican (client), and some of you are going to get assigned to work with a Democrat … and if that’s a problem for you in this class, then you ought not to take it, because we are going to provide the best nonpartisan analysis that we can possibly provide to these elected members so that they can make the best decisions they can make for our state.” 

It was sort of like a pin drop when I said that. Nobody dropped the class. Those students did a fabulous job … A lot of those students were bio majors or chem majors — they weren’t political science majors. They did these reports on these topics, and some of them have now been passed into state law. So they were part of the ecosystem which created real change. 

The students … (also) testified in one of the Senate committee rooms in the Wisconsin Legislature… They presented. They were asked questions. Afterwards, one of the students came up to grab me and said, “Dr. Yackee, this is the professional thrill of my lifetime” …

That class is sort of a nutshell of what we’re hoping to accomplish in this undergraduate major.

What do we know about how to promote civil dialogue and find common ground and about how to teach people to do that?

One of the things that we know about teaching classes on talking across the political divide is the importance of establishing ground rules in terms of how those conversations are going to take place. One of our current faculty members, Associate Professor Amber Wichowsky, very much emphasizes curiosity. One of the ground rules for her classes is you need to be curious about how and why people feel differently than yourself … 

It’s innate human behavior to put people in different camps of “us” and “them” … If we come into conversations with that framing, we will not be successful. If we come in with a framing of curiosity and an openness to new perspectives and ideas — it is not that we’re looking to change people’s values, but we are looking to humanize the other because that is one step toward being able to listen to other people’s points of view and work across the political divide.

Free speech on campus is a hot topic these days. How do you hope the major and the skills that you’re providing students might create the kind of environment that you’d like to see on campus? 

Great question. I think of it like my bicep: I don’t work out as much as I should, but the more I work out that muscle, the stronger it gets. I think we don’t have enough opportunities for students to engage with people that are different than them and think differently than them.

Let me submit that a university is a place of ideas, so the most important kind of diversity is the diversity of ideas. It should be a fundamental job of ours to encourage those interactions … We’re going to do that in our classes, but we’re also going to do that by hosting politicians and practitioners and journalists that have different points of view. We’ve done that now for years, and we will continue to do that. 

So if this major is successful, how do you picture the campus will be different?

We hope that it would provide an outlet for students who are interested in applied politics and policy and careers in that space to have a fuller and richer UW-Madison educational experience … 

If we can position students with (these) skills … and they can be trained and ready to go when our country arguably needs them more than ever, then we will have done our job as educators, but we’ll also have done our job in promoting the Wisconsin Idea in a really important way.
