Climate change has a negative impact on food security. Researchers have now conducted a study to investigate the natural variation of different chickpea genotypes and their resistance to drought stress. The scientists were able to show that chickpeas are a drought-resistant legume plant with a high protein content that can complement grain cultivation systems even in urban areas. Read more ›

A commonly used strategy in the development of messenger RNA (mRNA) medicine is based on the destruction of disease-causing mRNA. Achieving the opposite and stabilizing health-promoting mRNA is still a great challenge. A research team has now overcome this challenge: the chemists developed the first active substance that inhibits the deadenylation of mRNA and thus prevents its degradation. Read more ›

Conventional catalysts for hydrogen production via water electrolysis usually contain precious metals and are expensive. However, cheaper alternatives have been developed -- for example, cobalt-manganese catalysts. They have a high activity and are stable over a long period of time. The decisive factor for these characteristics is their manganese content. Why manganese plays this essential role was unknown for a long time. The mechanism behind this has now been deciphered.

Researchers have identified new drug targets for therapies that could benefit patients with different forms of retinitis pigmentosa and other inherited retinal diseases. Using advanced proteomics techniques, they unveiled shared critical pathways in retinitis pigmentosa disease models. The study represents significant progress in understanding how the proteome may change in different retinal dystrophies. Read more ›

Australian researchers have identified a new, brain-based measure of chronic sleepiness that could be diagnosed in just two minutes, predicting whether someone is safe to drive, operate machinery, or even alert enough to sit an exam. Read more ›

How long do free neutrons live until they decay? This has been a hotly debated topic, because different measurement techniques lead to different results. A possible new solution has now been proposed: All the results can be explained, assuming there are different neutron states with different lifetimes. Read more ›

A new study has provided a detailed analysis of how mRNA vaccines circulate and break down in the human bloodstream. The research aimed to help improve the safety and effectiveness of these vaccines, including reducing the side effects that people commonly experience such as headaches, fever and fatigue.

New research has shown that over the long-term, standing more compared with sitting does not improve cardiovascular health (coronary heart disease, stroke and heart failure), and could increase the risk of circulatory issues related to standing, such as varicose veins and deep vein thrombosis.

Nager syndrome (NS) is an extremely rare disease that causes developmental problems and anomalies in facial bone structures and limbs. While the causative gene is known, its underlying mechanisms remain obscure. Researchers from Japan employed genetically engineered zebrafish and found that the mutation in the gene that causes NS, suppresses the Fgf8 levels. This, in turn, affects the expression pattern of a critical cell population called neural crest cells in... Read more ›
