Two back-to-back droughts in 2023 and 2024 caused the most severe decline in forest moisture and biomass (the total mass of living vegetation such as leaves, trunks and branches) in the Amazon since 1992, according to a study published in the journal PNAS. And many of the
Recent seismic imaging off Vancouver Island has revealed something extraordinary: a tear in the subducting oceanic plate beneath the Cascadia Subduction Zone. The finding briefly raised the public's hopes that Cascadia might be "shutting down," potentially lowering earthquake
Astronomers from the Chinese Academy of Sciences (CAS) have employed the Lijiang 2.4-m telescope to perform optical photometric and spectroscopic observations of a core-collapse Type IIP supernova designated SN 2024abfl. Results of the observational campaign, published April 2
Coral reefs are important in many ways, but they also play a major role in protecting much of the world's coastlines from erosion by blocking up to 90% of incoming wave energy. During a tropical cyclone, the waves breaking on reefs can be much larger than normal. This can
After looping around the moon, the Artemis II crew — and their capsule’s heat shield — are preparing for the mission’s final major test: coming home.
Geoscientists have long relied on different forms of lead to understand Earth's geological history and how it was created over billions of years. However, there is a mystery that has been puzzling scientists for decades: Earth is missing a massive amount of lead that ought to
In a three-year project, researchers at NIBIO have tested how biochar affects potato yields and soil quality under Norwegian conditions. The results show that biochar has little effect on yield, but that it may offer other benefits.
Earth's glaciers are continuing to shrink at alarming rates, with new international research revealing that 2025 was among the worst years on record for global ice loss. Published in the Climate Chronicles collection of Nature Reviews Earth & Environment, the study provides the
Alzheimer’s isn’t just one problem—it’s a tangled mix of biology, aging, and overall health. That’s why drugs targeting a single factor have fallen short, even as new treatments show modest benefits. Scientists are now pushing toward multi-pronged strategies, from gene editing
The European Space Agency has achieved a European first with Celeste, successfully transmitting a navigation signal from low Earth orbit, following the launch of the mission's first satellites on March 28.

Shock waves from tiny black holes in the early universe could explain how antimatter became so rare while matter is common.
A common eye-health nutrient, zeaxanthin, may also help the body fight cancer more effectively. Scientists discovered it strengthens T cells and enhances the impact of immunotherapy treatments. Found in everyday vegetables and supplements, it’s safe, accessible, and shows
Scientists have proposed a surprising new way to detect gravitational waves—by observing how they change the light emitted by atoms. These waves can subtly shift photon frequencies in different directions, leaving behind a detectable signature. The effect doesn’t change how
As drought conditions intensify across the American West and the impact of climate change accelerates, cities such as Phoenix, Denver and Las Vegas may face a sobering reality. While it certainly helps, water conservation may no longer be enough.
Deep underground in a Canadian mine, a refrigerator nearly 1,000 times colder than outer space has just reached its target temperature—a milestone that brings scientists one step closer to potentially detecting dark matter, the invisible material thought to make up most of the
A strange new kind of superconductivity has been uncovered in uranium ditelluride (UTe2), where electricity flows with zero resistance—but only under extremely strong magnetic fields that should normally destroy it. Even more surprising, the superconductivity disappears at
The acquisition of the radio frequency signal from the Artemis II crewed mission to the moon by NASA's Deep Space Network (DSN) is indicated by the peak in the data signal shown on the top computer screen.
Researchers have documented several cases of spatial orientation in tarantulas living both in trees and in underground burrows. Spatial orientation refers to the ability of an animal to understand where it is in three-dimensional space and how to navigate purposefully within
After a ten-day mission around the moon, the Artemis II astronauts will have traveled nearly 700,000 miles
Perovskite solar cells shouldn’t work as well as they do—but they do. Scientists have now discovered that defects inside the material actually help, creating networks that separate and guide electric charges efficiently. Using a novel imaging method, they revealed hidden
Mercury released into the oceans affects marine environments worldwide. Traditionally, its distribution and quantity have been estimated using marine biogeochemical simulation models.
As local governments and service providers search for the most effective ways to support people experiencing homelessness, a new report from Portland State University centers on problem solving in the experience of those navigating homelessness.
A new chip design from UC San Diego could make data centers far more energy-efficient by rethinking how power is converted for GPUs. By combining vibrating piezoelectric components with a clever circuit layout, the system overcomes limitations of traditional designs. The
A mysterious glow of gamma rays at the center of the Milky Way has long hinted at dark matter, but the lack of similar signals in smaller dwarf galaxies has cast doubt on that idea. Now, researchers propose a bold twist: dark matter might not be a single particle at all, but a
The four Artemis II astronauts who looped around the moon this week are expected to splash down soon. NASA's grand mission spells a return to human deep-space travel, with renewed interest in building a long-term moon base.

Medieval poets, including a Japanese noble, provided key descriptions to track down solar events
The Artemis II astronauts conducted a historic lunar flyby, gathered invaluable data and took in unprecedented moon views, but one of the most crucial moments of their 10-day mission is still to come: Friday's splashdown.
While the Artemis II astronauts have been protected from the icy vacuum of space on their journey, their bodies have nonetheless been left exposed to possibly high levels of radiation—a danger of space travel that NASA is anxiously waiting to study.
Cancer drugs known as BET inhibitors once looked like a breakthrough, but in real patients they’ve often fallen short. New research reveals a key reason why: two closely related proteins, BRD2 and BRD4, don’t actually do the same job. Instead, BRD2 acts like a “stage manager,”
On Earth, extreme solar activity often appears as beautiful, benign auroras. But venturing beyond the safety of the Earth's magnetic field, one faces the full brunt of a temperamental star that can suddenly erupt with flares and coronal mass ejections.
Materials databases lie at the heart of future data-driven discovery in energy-related fields, say researchers from Tohoku University. In an article published in the journal Precision Chemistry, they have examined how different types of databases, both computational and

An analysis of survey data on 77,567 people in 19 European countries, including the U.K., by Raphaël Piters, of Sorbonne University, France, found little change in attitudes to work between 1999 and 2017. The researcher analyzed answers to a series of questions about work asked
Generation Z men are less likely to vote for left-wing parties than women, and their political preferences can be linked to their sexist attitudes, a large-scale study has found. Research on 15,122 people in the UK and 23 other European countries found that politics is
Researchers at the Department of Energy's Oak Ridge National Laboratory developed a method to convert a commonly discarded hydrocarbon polymer into gasoline- and diesel-like fuels. The team has applied for a patent for the discovery, which treats polyethylene—the stuff of white
As large floods occur more frequently worldwide, many wonder what led to such devastating events. Greenhouse gas emissions from human activities, improper land management and forest removal increase flood frequencies and severity.
Daily travel plans and early warnings for extreme weather all rely on traditional numerical weather prediction. However, both traditional numerical weather prediction and AI forecasting large models have long suffered from systematic biases, which compromise forecast accuracy.
