Samuel Arman and colleagues’ close examination of tooth microwear among living and extinct kangaroo species suggests that most of the species living in Australia during the Late Pleistocene had a broad, generalist diet rather than being specialized grazers. This broad diet likely allowed them to survive the glacial-interglacial cycles that drove fluctuations in vegetation on the continent. The findings add more evidence to the idea that human hunting, rather than failure to adapt to climate changes, ...

Male and female mice both prefer social interaction with female mice under normal conditions, but both switch to preferring males when their survival is threatened, according to a new study by Anqi Wei and colleagues. These preferences are mediated by different neuronal circuitry in male and female mice related to dopaminergic neurons in the brain’s ventral tegmental area, the researchers found. The findings offer a clearer picture of the underlying biology of socio-sexual preferences. These preferences are essential for successful reproduction, ...

The study, published Jan. 10 in Science, shows that combined with steps to decarbonize the economy, storing CO2 in buildings could help the world achieve goals for reducing greenhouse gas emissions. “The potential is pretty large,” said Elisabeth Van ...

By Beth Miller In mechanobiology, cells’ forces have been considered fundamental to their enhanced function, including fast migration. But a group of researchers in the McKelvey School of Engineering at Washington University in St. Louis has found that cells can generate and use lower force yet move faster than cells generating and using high forces, turning the age-old assumption of force on its head. The laboratory of Amit Pathak, professor of mechanical engineering and materials science, found that groups of cells moved faster with lower force when adhered to soft surfaces with aligned collagen fibers. Cells have been thought to continually generate ...

Researchers led by Nanyang Technological University, Singapore (NTU Singapore) have developed a breakthrough technique that could lay the foundations for detecting the universe’s “dark matter” and bring scientists closer than before to uncovering the secrets of the cosmos. The things we can see on Earth and in space – visible matter like rocks and stars – make up only a small portion of the universe, as scientists believe that 85 per cent of matter in the cosmos comprises invisible dark matter. This mysterious substance ...

AMES, Iowa – Neal Iverson started with two lessons in ice physics when asked to describe a research paper about glacier ice flow that has just been published by the journal Science.   First, said the distinguished professor emeritus of Iowa State University’s Department of the Earth, Atmosphere, and Climate, there are different types of ice within glaciers. Parts of glaciers are at their pressure-melting temperature and are soft and watery.   That temperate ice is like an ice cube left on a kitchen counter, with meltwater ...

Prehistoric kangaroos in southern Australia had a more general diet than previously assumed, giving rise to new ideas about their survival and resilience to climate change, and the final extinction of the megafauna, a new study has found. The new research, a collaboration between palaeontologists from Flinders University and the Museum and Art Gallery of the Northern Territory (MAGNT), used advanced dental analysis techniques to study microscopic wear patterns on fossilised kangaroo teeth. The findings, published in Science, suggest that many species of kangaroos were generalists, able to adapt to diverse diets in response to environmental changes. More ...

The outer ear is unique to mammals, but its evolutionary origin has remained a mystery. According to a new study published in Nature from the USC Stem Cell lab of Gage Crump, this intricate coil of cartilage has a surprisingly ancient origin in the gills of fishes and marine invertebrates. “When we started the project, the evolutionary origin of the outer ear was a complete black box,” said corresponding author Crump, professor of stem cell biology and regenerative medicine at the Keck School of Medicine of USC. “We had been studying the development and regeneration of the jawbones of fishes, and an inspiration for us was Stephen ...

Scientists have called for the designation of a new United Nations Sustainable Development Goal (SDG) with the aim to conserve and sustainably use Earth's orbit, and prevent the accumulation of space junk. There are currently 17 SDGs, adopted by UN members in 2015 as a universal call to action to end poverty, protect the planet for future generations, and ensure all people enjoy peace and prosperity. But with growing numbers of satellites and other objects now orbiting our planet, there is growing concern that without some form of global consensus ...

Researchers have uncovered how egg cells prepare for the creation of life. Their work reveals the secrets of the Balbiani body, a remarkable structure that organizes essential molecules to guide early embryonic development. Using zebrafish models and cutting-edge imaging, the team discovered how this structure transforms from liquid droplets into a stable core, laying the groundwork for life itself. This discovery sheds light on the extraordinary precision of nature’s reproductive process. A new study led by Prof. Yaniv Elkouby and his team, including first co-authors Swastik Kar and Rachael Deis, from the Faculty of Medicine at the Hebrew University ...

PHILADELPHIA—Opioid misuse and specifically opioid use disorder (OUD), continues to represent a significant U.S. public health threat, with more than 6 million Americans aged 12 and older meeting the criteria for OUD in 2022. Efforts to ease the crisis have included the development of genetic testing to identify individuals most at risk for OUD. New research, out today in JAMA Network Open, questions the usefulness of 15 genetic variants from an algorithm meant to predict OUD risk that was recently granted pre-marketing approval by the Food and Drug Administration. It found that the testing could lead to both false positive and false negative results. The study was led by Christal ...

LA JOLLA (January 9, 2025)—Plants may burrow into the ground and stretch toward the sun, but they’re ultimately stuck where they sprout—at the mercy of environmental threats like temperature, drought, and microbial infection. To compensate for their inability to up and move when danger strikes, many plants have evolved ways to protect themselves by altering their physiology, such as building armor around parts of their body and roots called the periderm. However, since many plant biologists who study tissue development ...

Sabre-toothed predators – best know from the infamous Smilodon – evolved multiple times across different mammal groups. A new study, published today in Current Biology reveals why: these teeth were ‘functionally optimal’ and highly effective at puncturing prey. The study, led by scientists at the University of Bristol in collaboration with Monash University shows that long, sharp blade-like teeth gave sabre-tooth’s a real advantage as ...
