Global efforts to limit climate change require deep cuts to carbon emissions. However, global emissions are still growing. Currently, we emit roughly 42 billion metric tons of carbon dioxide from fossil fuel use and land use changes every year.
Researchers at the National University of Singapore (NUS) have built a molecular "leash" to pull directly on a force-sensing protein called Piezo1, and discovered it switches on at about 15 piconewtons, proving that it can be activated by physical tethers, not only by membrane
Why are frogs diverse in some parts of Africa's rainforests and less so in others? The patterns of cooling and glaciation during the last ice age would probably not have been your first answer or even your last-ditch guess, but it is, nonetheless, correct.
A new study shows that the ups and downs in house prices are far more dramatic than most people think—and that government policies play a big role in making them happen. The researchers analyzed housing markets in 23 OECD countries from 1990 to 2019. They found that during
The cell's endoplasmic reticulum (ER) plays a central role in protein synthesis, folding, and calcium (Ca²⁺) storage. When damaged, ER-phagy (self-eating) removes affected ER regions via double-membrane vesicles called autophagosomes. However, the mechanisms underlying its
For more than a century, the fruit fly has been a workhorse of the biological sciences that has helped scientists to make fundamental breakthroughs in fields such as genetics and neuroscience. As it turns out, human scientists are not the only ones learning during these
When making ethical decisions, university students appear to prioritize fairness and the fate of the worst-off over either reducing total harm or obeying unconditional moral precepts, according to a study published in PNAS Nexus. Woo-Young Ahn and colleagues have designed an
Billions of tons of carbon dioxide are being classified as "dealt with" in global climate plans before anyone can know whether that is true. UT Researcher Rosalie Arendt has given a name to this problem in a new Correspondence published in Nature: Schrödinger's carbon.

Mental load, invisible work, "the extra shift"; no matter the newly coined term, unpaid work in the domestic sphere, predominantly done by women, is a hidden burden eating away at the sleep and mental health of those tasked with it. This work is essential to keep everyone's
Can our forests adapt to a hotter and drier future climate? Temperatures are predicted to rise up to 5°C compared to pre-industrial times. Forest management needs to adapt to these conditions, which requires a better understanding of how heat and drought affect trees. A new
Nearly every object we interact with in our lives has a mass, but where does this mass come from? Modern physics says matter acquires its mass from interaction with a physical vacuum—it is not an empty space, but contains a complex structure. Investigating the system of a
Access to nutritious food is a fundamental pillar of human success, but such access has been unequal throughout history. In pre-industrial European societies, meat was a highly sought-after food, and access to it was often related to a higher social status.
Surface volatiles—chemical substances that easily become gases or fluids at relatively low temperatures and pressures—are transported into Earth through subduction zones, with some being transported into the deep mantle and others to shallower depths. According to conventional
Stem cells are the body's ultimate shape-shifters, sustaining tissues by balancing two competing demands: maintaining their own population and generating specialized descendants. In many tissues, some early descendants can revert to a stem cell state through a process known as
A new tool makes it possible to screen millions of tiny protein fragments and select those that can be recognized by the immune system. The CIC biomaGUNE Center for Cooperative Research in Biomaterials has developed epiGPTope, a system that uses machine learning to generate and
