Wildlife biologists used a novel technique to trace the movement of carbon through Arctic and boreal forest food webs and found that climate warming resulted in a shift from plant-based food webs to fungal-based food webs for several high-latitude species, with potential indirect effects on nutrient cycling and ecosystem function.

Many bacterial pathogens use small injection apparatuses to manipulate the cells of their hosts, such as humans, so that they can spread throughout the body. To do this, they need to fill their syringes with the relevant injection agent. A technique that tracks the individual movement of proteins revealed how bacteria accomplish this challenging task.

Researchers have fabricated a new high-performance shortwave infrared (SWIR) image sensor based on non-toxic colloidal quantum dots. They report on a new method for synthesizing functional high-quality non-toxic colloidal quantum dots integrable with complementary metal-oxide-semiconductor (CMOS) technology.

Researchers mapped how the measles virus mutated and spread in the brain of a person who succumbed to a rare, lethal brain disease. New cases of this disease, which is a complication of the measles virus, may occur as measles reemerges among the unvaccinated, say researchers.

New findings provide details about the hidden organization of the cytoplasm, showing it makes a big difference where in that cellular broth that messenger RNA (mRNA) get translated into proteins. The findings hold promise for increasing or altering the production of proteins in mRNA vaccines and therapies.

Researchers have discovered how amino acids activate a key cell, TORC1, which is a master regulator in living organisms that controls whether cells grow or recycle their contents in yeast. Notably, the team found that the amino acid cysteine is sensed by a protein called Pib2 and that the two bind together to trigger TORC1. This is important because faulty TORC1 has been linked to disease such as cancer.

A research group found that in female fruit flies, microorganisms enhance reproductive function, boosting the number of cells that form eggs and the number of mature eggs. This is done by controlling the release of hormones to speed up cell division in the ovaries, and limiting programmed cell death. These findings could improve reproductive medicine and could aid the development of new methods to enhance fertility.

A new technique to clone and reassemble DNA, dubbed CReATiNG, could simplify and lower the cost to make synthetic chromosomes. Potential applications are numerous, including pharmaceutical production, biofuel generation, cancer therapies, and environmental cleanup using modified organisms. The method adds a powerful, versatile tool to the burgeoning field of synthetic biology.

Researchers describe unusual trilobite fossils prepared as thin sections showing the 3D soft tissues during enrollment. The study reveals the soft undersides of enrolled trilobites and the evolutionary mechanism that allows arthropods to enroll their bodies for protection from predators and adverse environmental conditions.
