Organic carbon detected in Bright Angel rock formation on Mars
In September 2025, NASA announced that its Perseverance rover had discovered a potential biosignature, which is a substance or structure that might have a biological origin. A new paper, published in Science Advances, unambiguously confirms the detection of organic carbon, the bu
Commute stress can fuel workplace conflict, but research suggests a simple fix
Pothole season, summer construction season or maybe bad weather. No matter the time of year, it's no surprise commuters who drive to work may start their day already feeling a bit on edge.

Why AI rules in science matter now: Nature backs wider debate beyond mathematics
In an editorial, Nature endorses the "Leiden Declaration on Artificial Intelligence and Mathematics," which was published earlier this month by researchers from 15 different universities, including Rodrigo Ochigame (CADS) and David Holmes (FWN).

Plasma and graphene combine to protect metal surfaces from corrosion
Plasma is an ionized gas, often referred to as the fourth state of matter. Plasmas, which are created artificially by applying energy to a gas, are found in the fluorescent tubes that illuminate kitchens. However, they have many other possible applications, such as the production
Why Ho Chi Minh City's pollution sources may have been misread for years
Biomass burning, including the combustion of wood, charcoal and agricultural residues, is a major source of PM2.5, a fine particulate matter that degrades air quality and poses risks to human health. Much of this pollution is tracked by looking at levels of levoglucosan, a chemic
World's largest particle smasher halts for upgrade to boost hunt for dark matter
World's largest particle smasher halts for upgrade to boost hunt for dark matter
The world's most powerful particle accelerator will shutter operations Monday for four years of renovations to dramatically boost its collision capacity and the potential for unlocking one of the greatest mysteries of the universe: dark matter.
A good idea is not enough: Experts explain what helps digital health start-ups succeed
A new study by researchers at Kaunas University of Technology (KTU) in Lithuania has shown that a good idea alone is not enough for health startups to succeed. What matters most is access to data, health care institutions and funding.

Scientists discover a surprising link between vitamin C and brain health
Scientists discover a surprising link between vitamin C and brain health
Could something as simple as vitamin C help support a healthier aging brain? In a study of more than 2,000 older adults in Japan, researchers found that people with lower vitamin C levels in their blood also tended to have less gray matter and weaker connections in a key brain ne
The universe is less uniform than we thought—cosmology may need a radical rethink
Modern cosmology rests on a simple assumption: If we look on large enough scales, matter should be distributed evenly, with no preferred direction within the cosmos. This is known as the cosmological principle.
Why Facebook, video calls and artificial intelligence matter for age-friendly communities
Contrary to common stereotypes, seniors' digital savvy is surging. New research from Rutgers University-New Brunswick suggests one reason: Digital tools are essential for the development and maintenance of age-friendly initiatives—programs and policies designed to support and inc
Quantum semiconductor design could expand search for dark matter
Quantum semiconductor design could expand search for dark matter
Dark matter accounts for 85% of the matter in the universe, but scientists still do not know what it is made of. A study, published in Physical Review Letters, by Rice University researchers proposes a detector design that could help search for axions, hypothetical particles that
