The Rosetta Stone of bacterial communication may have been found. Although they have no sensory organs, bacteria can get a good idea about what’s going on in their neighborhood and communicate with each other, mainly by secreting and taking in chemicals from their surrounding environment. Even though there are millions of different kinds of bacteria [...]

Researchers have discovered and analyzed several new compounds, collectively called the ”EUK-400 series,” which could someday be used to prevent radiation-induced injuries to kidneys, lungs, skin, intestinal tract and brains of radiological terrorism victims.

Scientists have modified chlorophyll from an alga so that it resembles the extremely efficient light antennae of bacteria. The team was then able to determine the structure of these light antennae. This is the first step to converting sunlight into energy using an artificial leaf.
Using zebrafish, researchers have identified and described an enzyme inhibitor that increases the number of cardiac progenitor cells and influences the size of the developing heart. The task was accomplished primarily because of the powerful advantages of studying embryonic development in zebrafish, vertebrates whose transparent embryos develop rapidly, are small and easy to handle and, [...]
An atomic “coin” can display a superposition of heads and tails when it has been thrown. If you leave the decision where a quantum particle should go to a coin like this, you get unusual effects. For the first time, physicists have demonstrated these effects in an experiment with caesium.

Freshwater fish are an important part of the diet of many peoples around the world, but it has been unclear when fish became an important part of the year-round diet for early humans. A new study shows it may have happened in China as far back as 40,000 years ago.
The secret to longevity may lie in an enzyme with the ability to promote a robust immune system into old age by maintaining the function of the thymus throughout life, according to researchers studying an “anti-aging” mouse model that lives longer than a typical mouse.
Scientists have described the formation of the centromere, a key cellular structure in powering and controlling chromosome segregation and accurate cell division.
Giving a local anesthetic during a Cesarean section helps manage pain after the operation and can reduce consumption of painkillers, according to researchers. The researchers recommend local anesthetics as part of integrated pain management strategies for Cesarean section operations, provided that consideration is given to the cost.
