Two University of Victoria (UVic) geologists have integrated field geology with statistical modeling to give scientists a new view of the chemical reactions happening on ocean floors billions of years ago. The revised picture shows that big changes in the carbon cycle were
The building blocks of proteins, amino acids, are essential for all living things. Twenty different amino acids build the thousands of proteins that carry out biological tasks. While some are made naturally in our bodies, others are absorbed through the food we eat.
For more than a century, condensed matter physics has grappled with one of its greatest unsolved challenges: how to build superconductors that operate at room temperature and transmit electricity with no loss. Now, in a paper published in Nature, a team of Harvard physicists
Chosen families are evolving but remain a cherished—and vital—lifeline for many. Mention "communal living" and the image that may spring to mind is the free-love, back-to-the-earth hippy communes of the 1960s, complete with bandannas and fringed suede vests. But communal living
The high-performance semiconductor devices powering smartphone displays, AI computing, EV batteries and more are increasingly incorporating 2D materials to overcome silicon's scaling limits. To optimize these technologies, a University of Michigan Engineering team developed a
When most people think about corals, they imagine a tropical reef with crystal blue water, teeming with colorful fish. But, in the depths of the cold, murky Gulf of Maine, deep-sea corals thrive, feasting on a steady supply of organic matter raining down from the surface ocean.
For half the world's population, the water in their drinking glasses comes from below them. Groundwater also supplies 40% of global irrigation projects. Alarmingly, more than a third of the planet's aquifers, or groundwater basins, are dropping. Declining water tables leave
A new Murdoch University study has found that cold-blooded animals (ectotherms) are unable to adjust physiologically to daily temperature fluctuations, a limitation that could leave them increasingly vulnerable as climate change drives even greater temperature variability.
Climate warming can increase plant growth in permafrost regions by lengthening the growing season, speeding up plant metabolic processes, and allowing deeper root penetration as permafrost thaws. However, the capacity for additional vegetation to offset the carbon released

Nudibranchs are often referred to as the butterflies of the sea. Nudibranchs live worldwide, primarily in warm, shallow marine regions, and stand out for their flamboyant colors and diverse shapes. A team from the Max Planck Institute of Colloids and Interfaces in Potsdam and
Glittery sea worms and sea squirts fit for "The Lord of the Rings" universe might sound like pure fantasy, but they're very real creatures living in the deep sea. Some of these otherworldly ocean animals are even featured in the latest "Top 10 New Marine Species" list published

New observations by a team of US astronomers have cast fresh doubt on whether the lunar surface could host abundant water ice. Publishing their results in Science Advances, a team led by Shuai Li at the University of Hawaii at Manoa has shown that relatively pure ice (making up
"Project Hail Mary," the Ryan Gosling-led adaptation of the best-selling sci-fi novel from Andy Weir, is being praised for putting the science in science fiction. Although aliens, sun-draining microorganisms and galaxy-spanning spaceflight are all a part of the story of a
A court ruling that blocks Trump administration vaccine policy is a win for science. But much work remains to rebuild trust in vaccines.
Tiny pieces of plastic, called microplastics, are showing up everywhere, even in the water in clouds, rain, and snow—and they may be affecting our weather and temperatures. A study published in Environmental Science & Technology and led by Hosein Foroutan, associate professor

An astoundingly strong heat wave is not just setting records across the western U.S.—it’s pulverizing them
Every time we do a load of laundry, tiny fibers of polyester escape from our clothes and slip down the drain. These microfibers, so small they can be invisible to the naked eye, are among the most common forms of microplastic in the ocean. Yet, new research published in Journal
Like the males of many animal species, male Drosophila melanogaster fruit flies, a commonly studied lab animal, are aggressive toward one another and even fight when competing for resources such as food and females. Researchers in the lab of David Anderson have been studying
For millennia, sling bullets served as a hand-thrown projectile that could be used to fend off enemies. At Hippos, 70 sling bullets made of lead have been recovered over the course of fieldwork and excavation. However, while many are bare or depict scorpions and thunderbolts,

When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting that involves construction of spindles to carefully separate the DNA after replication. Instead, they use a process called binary fission, which is faster
Despite polyethylene terephthalate (PET) being one of the most widely recycled plastics, only about 20% of used PET bottles are actually recovered as high-quality raw materials. The majority are transformed into lower-grade fibers or fillers before eventually being discarded.
For her Ph.D. at VUB and KULeuven, Aarushi Caro created a kind of systematics for dendritic cells, a special group of immune cells in the fight against cancer. Until now, there was a lot of confusion about the different types of dendritic cells. "Scientists worldwide use
