Many biological processes are regulated by electricity—from nerve impulses to heartbeats to the movement of molecules in and out of cells. A new study by Scripps Research scientists reveals a previously unknown potential regulator of this bioelectricity: droplet-like structures called condensates. Condensates are best known for their role in compartmentalizing the cell, but this study shows that they can also act as tiny biological batteries that charge the cell membrane from within. The team showed that when the electrically charged condensates collide with cell membranes, they change the cell membrane voltage—which affects the amount of electrical charge that flows across…
Christmas can be hard. For some people, it increases loneliness, sadness, hopelessness and family tension, and the holiday season has a way of turning ordinary worries into urgent ones. Not because something terrible is guaranteed to happen, but because there’s often more at stake: money, time, family dynamics, travel, and expectations. A great study found a small but steady decline in people’s well-being in the run-up to Christmas. A psychological process that often occurs under this pressure is worry. It helps to separate worry from anxiety, because although they feel similar, they are not the same. Worry it’s mostly a…
By merging causal genetics with network control theory, this study reveals hidden drivers of long-term COVID, offering new insight into why the condition affects patients so differently. Study: Integrated multi-homics framework for causal gene discovery in Long COVID. Image credit: Daisy Daisy/Shutterstock.com The coronavirus disease 2019 (COVID-19) pandemic has had a heavy impact on human life and health starting in 2020. Although the severity of the pandemic has faded, its long-term consequences continue to afflict hundreds of thousands of survivors. A recent study published in the journal PLoS Computational Biology examines genes underlying risk for long-term COVID using multi-omics tools.…
Skin care tiles have been attracting a lot of attention lately, and there’s a good reason for that. When your skin suddenly starts feeling dry, tight, flaky, or strangely sensitive, it’s easy to assume you need more water, a heavier moisturizer, or a different cleanser.

Below, we explain what these ingredients are, signs your skin needs more of them, and what you can do to replenish…

Estrogen, the main female sex hormone, although it performs some functions in men, is involved in a myriad of processes, which is why the body changes so much during menopause. This is because estrogen regulates hundreds of genes. A study led by the Spanish National Cancer Research Center (CNIO) now shows how they do it, looking directly into the cell’s nucleus. The researchers discovered that estrogen’s action depends on a physical property of DNA: its ability to twist or supercoil. “We discovered that the way the DNA molecule is coiled and unwound, its topology, is key for cells to respond…
With Washington U. in St. Louis Sweeteners such as aspartame, found in Equal packets, sucralose (Splenda) or sugar alcohols are often seen as healthier alternatives to refined sugar (glucose) foods. But that assumption is being challenged by new scientific research, including the recent finding that the sugar alcohol sorbitol is not as harmless a sugar substitute as we once thought. The study in Scientific Signalingfollows a series of research detailing the harmful effects of fructose on the liver and other systems from Gary Patti’s lab at Washington University in St. Louis. Patti, a professor of chemistry and genetics and…
