Discovery of molecular switch explains how bacteria control their protein biosynthesis through cell metabolism
Protein biosynthesis—the process whereby cells produce protein molecules, which are essential for life and growth—is a highly complex and strictly regulated affair. An interdisciplinary team led by LMU biologist PD Dr. Jürgen Lassak has now disc.....»»
New catalyst can convert methane into useful polymers
Although it is less abundant than carbon dioxide, methane gas contributes disproportionately to global warming because it traps more heat in the atmosphere than carbon dioxide, due to its molecular structure......»»
Team links comet water to Earth"s oceans
Researchers have found that water on Comet 67P/Churyumov–Gerasimenko has a similar molecular signature to the water in Earth's oceans. Contradicting some recent results, this finding reopens the case that Jupiter-family comets like 67P could have h.....»»
Enzyme study sheds light on the molecular mechanism behind "sleepiness"
Recent research has observed that chemical modifications called phosphorylation of proteins in brain neurons dynamically regulate sleep and wakefulness. But the protein kinases that suppress sleep and the dephosphorylation enzymes that control sleep.....»»
Hidden DNA in plants reveals secrets of photosynthesis
Scientists have uncovered genetic variation in the unexplored DNA of the photosynthetic and energy factories of Arabidopsis plants, which plays a crucial role in the efficiency of photosynthesis in plants. These insights—published Nov. 27 in the Pr.....»»

How a species of ground squirrel manages to go without food and water over the winter months
A team of molecular and physiology specialists at the Yale University School of Medicine has uncovered some of the hibernating secrets of thirteen-lined ground squirrels, and have partly explained how it manages to avoid thirst during its long winter.....»»
A rising tide of e-waste, made worse by AI, threatens health, the environment and the economy
Our growing reliance on technology at home and in the workplace has raised the profile of e-waste. This consists of discarded electrical devices including laptops, smartphones, televisions, computer servers, washing machines, medical equipment, games.....»»
Researchers use eDNA metabarcoding to identify pollinators, aiming to boost crop production
A Curtin University study has revealed that a new method of capturing DNA could provide farmers with a valuable tool for boosting crop production—while also benefiting the environment......»»
Scientists reveal structural link for initiation of protein synthesis in bacteria
Within a cell, DNA carries the genetic code for building proteins. To build proteins, the cell makes a copy of DNA, called mRNA. Then, another molecule called a ribosome reads the mRNA, translating it into protein. But this step has been a visual mys.....»»
