Whenever a cell divides, it has to split its chromosomes perfectly between two daughter cells, and even a single mistake can be disastrous. Now, researchers from Japan have found that one of the key structures that makes ...
Scientists have proposed what they believe is the first method for detecting "mirror life"—a hypothetical form of life made from molecular building blocks that are the mirror image of those found naturally on Earth. Researchers ...
Just like gloves, molecules can have left- and right-handed—or mirror-image—forms. Because the left- and right-handed molecules are still very similar, scientists have had trouble separating them from each other. But a team ...
Many structures in biology are bounded by membranes, but not all of them. Droplets of a liquid called a coacervate, which form when oppositely charged molecules come together in water, have attracted attention as models for ...
Earlier this year, an outbreak of Andes hantavirus on a cruise ship, which killed three passengers and sickened 13, highlighted the lack of approved vaccines or treatments for the virus. In a study published in Nature, scientists ...
In the early 1980s, scientists observed an anomaly. Embedded within cell membranes, they identified ion channels with extraordinarily high conductance. These so-called "BK" (Big K, or Big Potassium) channels had roughly 10 ...
Molecules can spontaneously organize into complex, ordered structures through a process known as self-assembly. Among these structures, soft quasicrystals display unusual patterns that do not repeat regularly like conventional ...
The site of a former U.S. military base in Greenland was ice-free at a time when summers were a few degrees warmer than today, according to a new University at Buffalo–led study of ancient sediment recovered from beneath ...
Transforming a soybean processing byproduct into a material for skin protection and repair is the prospect outlined by a study that used okara, a residue from the production of tofu and soy-based beverages, to obtain a bioactive, ...
Scientists have long been interested in cellular nanodiscs, tiny particles made from natural cell membranes that mimic many of the functions of living cells. While previous studies demonstrated the therapeutic potential of ...
