“Bioturbation is also important for seabed and wider ocean ecosystems. We have a good understanding of how invertebrates contribute to global bioturbation – but until now, we have been missing half the story. Our study is the first to attempt to quantify the bioturbation impact of fish, and it shows they play a significant, widespread role.”
How overfishing threatens nature’s underwater engineers
Co-author Callum Roberts said, “We also found that species with the highest bioturbation impacts are among the most vulnerable to threats such as commercial fishing.”
“Many of the largest and most powerful diggers and disturbers of seabed sediments, like giant skates, halibut and cod, have been so overfished they have all but vanished from our seas. These losses translate into big, but still uncertain, changes in the way seabed ecosystems work.”
For now, predicting the exact timing of the spacecraft’s reentry remains difficult. Marco Langbroek estimates it could occur around May 10, though the forecast will become more accurate as the date approaches. The uncertainty is largely due to heightened solar activity — the Sun’s current active phase is heating and expanding Earth’s atmosphere, increasing atmospheric drag and causing orbiting objects to lose altitude more quickly.
It’s equally challenging to predict where any surviving debris might land. The location will depend on the precise moment the spacecraft reenters and starts to break apart.
Typically, the risk to populated areas is low, with debris more likely to fall into remote regions of the ocean. Due to its robust construction, if it lands on solid ground, it could provide valuable insights into the durability of spacecraft materials after prolonged exposure to space.
However, even though the risk is small, uncontrolled reentries are never entirely without danger.
This is not the first time reentry predictions have been made for Kosmos 482.
In 2018, Russian astronomer Pavel Shubin estimated that the spacecraft would crash between 2023 and 2025 . Further analyses in 2019 and 2022 refined these predictions, with simulations indicating a reentry window between mid-2024 and mid-2027, most likely around 2025–2026.
Inflammation’s hidden retinal imprint
Another important finding from the study points to genetic variants linked to inflammatory processes in the brain, which may also play a role in structural changes observed in the retina.
These results lend additional support to the inflammation hypothesis of schizophrenia — the idea that inflammation could drive the onset or progression of the disorder.
“If this hypothesis is confirmed, inflammation could be interrupted by medication, potentially enabling us to improve treatment possibilities in the future,” Rabe explained.
“Understanding the anatomy of the Uturuncu volcanic system was only possible thanks to the expertise within the research team. This enabled us to combine various advanced geophysical imaging tools with modelling of the rock properties and their interactions with fluids,” said Professor Haijiang Zhang, the co-author from the School of Earth and Space Sciences, University of Science and Technology of China, in the press release.
The team suggests that the study techniques be valuable for investigating over 1400 potentially active volcanoes and the many other seemingly inactive, zombie-like volcanoes.
The study involved researchers from the University of Science and Technology of China, the University of Oxford, and Cornell University.
C2 molecule production
Even though other experiments have achieved artificial photosynthesis using biological materials, Yang’s team chose copper, an inorganic material with lower selectivity for desired chemical reactions than biological catalysts. However, copper offers significant advantages such as greater durability, stability, and longer operational life, all critical for scaling up future applications.
While LiSA experts developed the device’s cathode and anode components, the integration with metal contacts was carried out using instruments at Berkeley Lab’s Molecular Foundry. During testing, a solar simulator replicating continuous sunlight demonstrated that the system could efficiently convert CO₂ into carbon-carbon (C2) molecules, essential building blocks for a wide range of industries.
Education Dept. Investigating Chicago Public Schools
A conservative nonprofit, Parents Defending Education, alleges Chicago public schools has an academic-achievement initiative that discriminates against students on the basis of race and the Department of Education is investigating the complaint.
The complaint concerns a recent program aimed at helping Black students academically, the Black Students Success Plan, and claims that it "violates Title VI" of the Civil Rights Act "by focusing on remedial measures only for Black students, despite acknowledging that Chicago students of all races struggle academically," the release states.
The news follows a threat, which cited the same section of the Civil Rights Act, issued by the Trump administration earlier this month to cut off more than $1 billion in federal funding to CPS over programs that focus on diversity, equality and inclusion.
LA Port Braces for 35 Percent Drop As Trump Tariffs Hit
Shipments from China to the West Coast are expected to fall sharply next week, with cargo to the Port of Los Angeles projected to drop by more than a third, as President Donald Trump's new tariffs prompt major U.S. retailers to curb import orders.
Gene Seroka, who heads the nation's busiest container port, told CNBC's "Squawk Box" that American retailers are halting large orders from China in response to the new duties, significantly reducing incoming cargo volume.
"According to our own port optimizer, which measures the loadings in Asia, we'll be down just a little bit over 35% next week compared to last year. And it's a precipitous drop in volume with a number of major American retailers stopping all shipments from China based on the tariffs," Seroka said.
Beijing responded swiftly with retaliatory tariffs, raising the combined levies of the two countries to more than 100% on many goods. Treasury Secretary Scott Bessent has called the standoff "unsustainable," but no significant negotiations have emerged to resolve the dispute.
Economic analysts are already warning of broader impacts. Torsten Slok, chief economist at Apollo Global Management, has outlined the risk of job losses in the transportation and retail sectors, shrinking inventories, and a possible recession if trade disruptions persist through summer.
Despite these concerns, U.S. retailers are temporarily buffered by inventory stockpiled ahead of Trump's tariff hike. Seroka estimated that companies have five to seven weeks of inventory before product shortages become visible to consumers.
ICE Dismantles Marriage Fraud Operation; 4 Charged
Immigration and Customs Enforcement has dismantled a nationwide marriage fraud operation that resulted in four people being arrested in connection with facilitating visa and marriage fraud.
The sham marriages were arranged to help those who entered the U.S. illegally gain immigration benefits, ICE announced Monday.
Ella Zuran, 65, Tatiana Sigal, 74, and Alexandra Tkach, 41, of New York City, along with Shawnta Hopper, 33, of Sicklerville, New Jersey, are alleged to have been the ringleaders of the operation. Zuran, Sigal, and Tkach were arrested and charged in March.
ICE Homeland Security Investigations began the investigation in April 2022 with assistance from U.S. Citizenship and Immigration Services and the Department of State Diplomatic Security Service.
The inquiry resulted in 10 more arrests last Thursday.
Border Patrol Gets Assist From Mexican Navy
U.S. Customs and Border Patrol posted a video Monday of a patrol boat intercepting and ramming a suspected human smuggling craft off the California coast.
Border Patrol Chief Michael Banks said the operation to intercept the border-crossing criminals might not have happened if not for a tip from the Mexican navy.
Banks credited Mexican military commanders with passing along information about a boat Border Patrol was unable to stop and figured it was heading for the U.S. Banks said CBP's West Coast Air and Marine Operations agents spotted the boat in open water off San Diego and ordered the operators to stop.
The boat continued at a high rate of speed. A few moves later the evasion ended. All was caught on video. Banks initially reported that two suspected human smugglers were being detained after the stop.
In a later post, Banks updated the case and reported that there were three apparent smugglers onboard who were trying to sneak 16 others on the vessel to shore.
"The smugglers now face felony charges for alien smuggling ... while the others will be prosecuted for felony illegal re-entry," Banks said. "Even in the open ocean," said the chief, "the border has a line — and we will defend it."
