The Trump administration wants to allow deep-sea mining for critical minerals near the American territories of Guam and the Northern Mariana Islands. Residents are worried about environmental impacts.

Researchers have created a method called optovolution that uses light to guide the evolution of proteins with dynamic behaviors. By engineering yeast cells so their survival depended on proteins switching states at the right time, scientists could rapidly select the best-performing variants. The technique produced new light-sensitive proteins that respond to different colors and improved optogenetic systems. It even evolved a protein that behaves like a tiny logic gate, activating genes only when two signals are present.

Global warming has picked up speed in the past decade, according to a new analysis from the Potsdam Institute for Climate Impact Research (PIK). By removing short term natural influences such as El Niño, volcanic eruptions, and solar cycles from temperature records, researchers uncovered a clear acceleration in the planet’s long term warming trend beginning around 2015.

Researchers have found hundreds of metabolic enzymes attached to human DNA inside the cell nucleus. Different tissues and cancers show unique patterns of these enzymes, forming a “nuclear metabolic fingerprint.” Some of the enzymes gather around damaged DNA to assist with repair. The discovery reveals an unexpected link between metabolism and gene regulation that could influence how cancers grow and respond to treatment.

Scientists have found a way to significantly boost “blue energy,” which generates electricity from the mixing of saltwater and freshwater. By coating nanopores with lipid molecules that create a friction-reducing water layer, they enabled ions to pass through much more efficiently while keeping the process highly selective. Their prototype membrane produced about two to three times more power than current technologies. The discovery could help bring osmotic energy closer to becoming a practical renewable power source.

Exercise normally boosts the body’s ability to use oxygen, a key marker of health and longevity — but high blood sugar can block that benefit. Researchers found that a ketogenic diet helped mice normalize blood sugar and dramatically improved how their muscles responded to exercise. Their muscles became better at using oxygen and built more endurance fibers. The results suggest diet and exercise may work together in surprising ways to improve metabolic health.

Pre-workout supplements promising extra energy for workouts may come with a hidden cost: severely reduced sleep. A study of people aged 16–30 found users were more than twice as likely to sleep five hours or less per night. Many of these products pack huge doses of caffeine and stimulants that can linger for hours. Researchers say the findings raise concerns about the impact on young people’s health and development.

A prehistoric mass grave in Serbia reveals that more than 77 people—mostly women and children—were deliberately killed in a brutal act of violence about 2,800 years ago. Genetic evidence suggests the victims came from different communities, indicating the massacre may have been a calculated message during fierce territorial struggles in Iron Age Europe.

DNA is revealing that many animals once thought to be a single species may actually be several hidden ones. But research on Bornean fanged frogs shows the line between species can be blurry—an important challenge when deciding what wildlife needs protection most.

Plants constantly juggle oxygen inside their cells, but scientists have now discovered a surprising twist in how that balance works. Researchers at the University of Helsinki found that mitochondria—the cell’s energy generators—can actively pull oxygen away from chloroplasts, the structures responsible for photosynthesis. This previously unknown interaction suggests mitochondria can effectively “drain” oxygen inside plant cells, altering photosynthesis and the production of reactive molecules that help plants respond to stress.

Astronomers have created the largest and most detailed 3D map yet of a glowing signal from the early universe, revealing hidden galaxies and gas from 9-11 billion years ago. By analyzing faint “Lyman-alpha” light emitted by energized hydrogen, scientists used an advanced technique called line intensity mapping to capture not just the brightest galaxies but also the vast cosmic structures surrounding them.

When NASA’s DART spacecraft deliberately crashed into the asteroid moonlet Dimorphos, it did more than change the asteroid’s local orbit — it slightly shifted the path of the entire asteroid pair around the Sun. The impact blasted debris into space, doubling the force of the spacecraft’s hit and nudging the system’s solar orbit by a tiny but measurable amount. It marks the first time humans have altered the trajectory of a celestial object around the Sun. The result strengthens the case for using spacecraft impacts as a future planetary defense strategy.

In 2025, exports of major petroleum-based transportation fuels, including distillate fuel oil, motor gasoline, and jet fuel, averaged 2.4 million barrels per day (b/d), about the same as the previous year. Distillate fuel oil, commonly sold as diesel, accounts for more than half of these exports, and the entirety of the annual decrease. Exports of gasoline and jet fuel increased slightly in 2025 over 2024. As in previous years, Mexico was the most popular destination by volume for all three fuels, especially gasoline.

Wisconsin’s average age is slightly higher than the national average age. 

According to data from the Wisconsin Department of Health, which shows the average of ages between 2019 and 2023, the most recent data available, the national average is 38.7. 

In Wisconsin, the average age is 40.1 for the same time period.

Those numbers reflect the rapidly aging baby boomer generation, which is skewing Wisconsin’s population to individuals over 65, according to Wisconsin Public Radio.

Between 2010 and 2020, this demographic grew from 777,000 people to more than 1 million and is projected to expand to 1.3 million by 2030. Meanwhile, the working-age demographic in the state is holding steady, meaning that the population of those over 65 is growing as a percentage of the total.

This fact brief is responsive to conversations such as this one.

A conservative Wisconsin Supreme Court justice first elected in 2007 announced Monday that she will not seek a third 10-year term next year, giving liberals another chance to expand their majority as cases affecting redistricting, union rights, school funding and other hot button issues await.

Justice Annette Ziegler, 62, becomes the second conservative justice in as many years to decide against seeking reelection after liberals took majority control of Wisconsin’s highest court in 2023. Liberals held onto their majority last year in a race that broke national spending records and saw billionaire Elon Musk traveling to the state to hand out $1 million checks to conservative voters.

There’s another election on April 7 for the open seat caused by conservative Justice Rebecca Bradley’s decision not to run for reelection. The liberal candidate, Appeals Court Judge Chris Taylor, has outraised her conservative opponent, fellow Appeals Court Judge Maria Lazar, allowing her to spend more on television ads in what so far has been a low-profile race given that the court’s majority is not on the line.

Liberals are seeking to win their fourth Supreme Court race in a row dating back to 2020 and solidify their hold on the court.

Ziegler’s decision to step down means there will be another open race next year. If liberals win this year, their majority would increase to 5-2, and in 2027 they could grow it to 6-1. If the conservative candidate wins this year, the liberal majority would remain 4-3, and next year the best conservatives could do would be to keep it at 4-3.

Ziegler consistently sided with fellow conservatives justices, including in 2020 when the court fell one vote short of overturning President Donald Trump’s election loss that year. Ziegler was in the minority after a conservative swing justice sided with liberals.

Cases expected to come before the court in coming years include challenges to congressional district maps, the future of a state law that effectively ended collective bargaining for most public workers and an effort to increase spending on public schools.

Liberals have struck down a state abortion ban law and ordered new legislative maps since taking control of the court, fueling Democrats’ hopes of capturing a majority this November.

Ziegler, who was chief justice between 2021 and 2025, previously served as a circuit court judge in Washington County for 10 years.

“Now is the right time for me to step away to spend more time with my husband, kids and grandkids,” she said in a statement.

“I am incredibly proud that in all my elections I had support from a broad spectrum of legal, civic, law enforcement and political leaders — both Democrats and Republicans — who believed in my commitment to fairness, ethics and the rule of law,” Ziegler said.

The election to replace Ziegler is April 6, 2027.

Two attempts to peel back the veil of secrecy over the proliferation of data centers, including one by Wisconsin Watch reporter Tom Kertscher, are being honored in this year’s Openness in Government Awards, or Opees, bestowed by the Wisconsin Freedom of Information Council.

In advance of national Sunshine Week (sunshineweek.org), March 15-21, the council has named the winners of its 20th annual Opees. These recognize outstanding efforts to protect the state’s tradition of open government, as well as highlight some threats to it. Winners have been invited to appear at a free public event in Madison on March 19. (See WFOIC website for details.)

The winners are:

Public Openness Advocate (Popee): Vilas County District Attorney Karl Hayes. District attorneys in Wisconsin are statutorily empowered to enforce the state’s open records and open meetings laws, but in practice rarely do so. Early this year, Hayes showed how it can be done, warning officials in the town of Presque Isle that they needed to comply with a nearly year-old request from the Lakeland Times newspaper for records regarding the town’s computers. His intervention succeeded, and the records were released. Other DAs might look for occasions where they can turn the lever in favor of openness.

Citizen Openness Advocate (Copee): Midwest Environmental Advocates. This nonprofit public interest law firm last year filed two pivotal lawsuits challenging the secrecy surrounding data center projects. The first, against the city of Racine, forced the prompt release of water usage projections for Microsoft’s Mount Pleasant campus. The second lawsuit, against the state Public Service Commission (PSC), contested the “trade secret” status of energy demand data for Meta’s proposed data center in Beaver Dam; that case is pending. Kudos to MEA for insisting on the public’s right to know.

Media Openness Advocate (Mopee): The Badger Project. In recent years, this nonprofit news outlet has been requesting records from police departments around the state about internal investigations of police officers and suing when they are not provided. In 2025, it filed three such lawsuits — against a police department in Racine County, the state Department of Transportation and St. Croix County. All led to the release of records. The Badger Project is now appealing St. Croix County’s refusal to pay attorney fees, which could lead to the overturning of a deeply problematic state Supreme Court decision. Fingers crossed. 

Open Records Scoop of the Year (Scoopee): Tie: Tom Kertscher of Wisconsin Watch; Danielle DuClos of The Cap Times. Among much other good reporting on openness issues, the work of these two journalists stands out. Kertscher pulled back the curtain on the secrecy surrounding data centers, including at least four projects in which local officials signed nondisclosure agreements with the companies. And DuClos reported on how the state Department of Public Instruction secretly investigated more than 200 Wisconsin K-12 educators accused of sexual misconduct or grooming behaviors toward students, prompting a statewide audit and legislative action.

No Friend of Openness (Nopee): Deborah Kerr, superintendent of the St. Francis School District. While there were other contenders for this award, there was also little question that Kerr would be the winner and new champion. Last June, she threatened to have a TMJ4 News reporter and camera operator arrested for wanting to film a school board meeting “because you did not give us any notice or tell us why you were here,” neither of which is required. The jaw-dropping video (see for yourself at https://tinyurl.com/zvam889a) went viral, and Kerr issued a weak apology, but her eruption is one for the ages. Credit reporter Megan Lee for her deft handling of the situation.

Whistleblower of the Year (Whoopee): John Sigwart. This former Port Washington city council member refused to keep the public in the dark about a clandestinely proposed microchip production facility, revealing that local officials had signed nondisclosure agreements. The city’s mayor retaliated by stripping Sigwart of his committee appointments, precipitating an end to his many years of public service, said an editorial in the Ozaukee Press. Sigwart died in August at age 80, but his example of courage will live on.

The Wisconsin Supreme Court is scheduled to hear oral arguments Wednesday in a case that highlights how judges can apply different interpretations of the law and constitution to suit their ideological viewpoints.

The case resulted from disagreements between the Republican-led Legislature and Attorney General Josh Kaul following the 2018 lame-duck session that limited the powers of the incoming Democratic administration. 

The lawsuit, which the Legislature filed in 2021 when there was a conservative majority on the state Supreme Court, focuses on who has oversight of the dollars the state receives from legal settlements. The Legislature argues the 2018 law requires the attorney general to put money from a financial settlement in the general fund, which state lawmakers control. Kaul argues that he can put settlement funds in accounts that the Department of Justice oversees and still comply with the law.

In December 2024, the 2nd District Court of Appeals in a 2-1 ruling reversed part of a circuit court decision that said Kaul could continue to direct settlement dollars into DOJ-controlled accounts.

The Appeals Court opinion was written by Judge Maria Lazar, a conservative who is running for a seat on the Wisconsin Supreme Court in April against liberal Appeals Court Judge Chris Taylor. Lazar ruled the language in the 2018 law aligns with the Legislature’s arguments that settlement dollars belong in the general fund. 

“Despite the legislation expressly designed to bring all settlement funds under legislative control and despite the simple and plain language of that legislation, the Attorney General has continued to act precisely in the manner which the Legislature sought to end,” Lazar wrote.

But in a dissent, retiring Appeals Court Judge Lisa Neubauer, the only liberal on the Waukesha-based District 2 Court of Appeals, criticized Lazar for basing her decision on what the Legislature intended, rather than a strict reading of various clauses in the law that may give the attorney general wiggle room.

The oral arguments this week follow a series of decisions in recent years on lawsuits challenging the separation of powers between the Legislature and the executive branch. In June, the court unanimously struck down a portion of the 2018-era lame-duck laws that required the attorney general to receive approval from the Legislature’s budget-writing committee to settle most civil cases. For the 4-3 divided liberal-majority court, the rulings in these cases have shown agreement among the justices over the need for clear boundaries between the core powers of the branches of government, legal experts said. 

Where this latest lawsuit differs is the debate seems focused more on the language of the law than the separation of powers, said Chad Oldfather, a professor at the Marquette University Law School. Typically the conservative approach to statutory interpretation has been to focus on the basic meaning of the law while the liberal approach has been to examine the law’s intent. That has been the opposite in this case, Oldfather said.  

“The advocates are kind of flipping a little bit the usual ideology of the statutory interpretation approach,” Oldfather said. “And all that’s going on while it’s clear that there are some people on the court who want to fundamentally shift the way the court does statutory interpretation. So there’s a real interesting mix of issues going on in this case.” 

The law in question has been wrapped up in a yearslong debate over separation of powers that has made its way to justices in recent years, said Bryna Godar, a staff attorney at the State Democracy Research Initiative at the University of Wisconsin-Madison Law School. In many of those cases, the Supreme Court opinions have shown the justices interested in balanced branches of government. 

“There seems to be an inclination to reinstate greater separation of powers between the branches and preserve the important roles of various actors, whether that’s the attorney general or the governor or the Legislature,” Godar said. 

For example, in a 6-1 decision in 2024, with Justice Annette Ziegler dissenting, the court ruled the Legislature’s Republican-led budget-writing committee could not block spending by the Department of Natural Resources for the Knowles-Nelson Stewardship Fund. 

“While the legislature’s motivation for overseeing the public fisc may be well-intentioned, fundamentally, the legislature may not execute the law,” Justice Rebecca Bradley, a member of the conservative bloc, wrote in the majority opinion. “The people gave the executive alone this power.”

In the 7-0 decision last June on the Legislature’s approval of the attorney general’s civil case settlements, Justice Brian Hagedorn wrote that the constitution does not give lawmakers the ability to execute the law when there are financial decisions. 

“If the Legislature has a constitutional interest in the execution of the laws every time an executive action involves money, there would be virtually no area where the Legislature could not insert itself into the execution of the law,” Hagedorn wrote. 

There are still areas of disagreement among the court in these types of cases. Last July, the court reached a 4-3 decision in a lawsuit between Gov. Tony Evers and the Legislature, which determined 2018 lame-duck legislation that gave a legislative committee the ability to delay rules and policy changes from executive agencies was unconstitutional.

In that case, the court’s four liberal justices were in the majority. Hagedorn wrote an opinion both concurring and dissenting with the majority’s decision, while Bradley and Ziegler dissented.

“The majority has created a grave constitutional imbalance by strictly construing, and thus confining, the constitutional powers of the legislative branch while not doing the same when it comes to the power of the executive branch,” Ziegler wrote.
