Gemini south reveals origin of unexpected differences in giant binary stars

Gemini south reveals origin of unexpected differences in giant binary stars

Astronomers have confirmed that differences in binary stars’ composition can originate from chemical variations in the cloud of stellar material from which they formed. The results help explain why stars born from the same molecular cloud can possess different chemical composition and host different planetary systems, as well as pose challenges to current stellar and planet formation models. …read more

Possible alternative to antibiotics produced by bacteria

Possible alternative to antibiotics produced by bacteria

Many bacteria produce substances to gain an advantage over competitors in their highly competitive natural environment. Researchers have discovered a new so-called lantibiotic, namely epilancin A37. It is produced by staphylococci that colonize the skin and acts specifically against their main competitors there, the corynebacteria. This specificity is presumably mediated by a very special mechanism of action, which the researchers were able to decipher in detail. …read more

Liquid droplets shape how cells respond to change

Liquid droplets shape how cells respond to change

New research has shown that cells regulate cAMP/PKA signaling by forming liquid droplets that segregate excess PKA catalytic subunits where they can do no harm. Some cancers may block the formation of liquid droplets, leading to hyperactive signaling and tumor formation. …read more

New copper-catalyzed C-H activation strategy

New copper-catalyzed C-H activation strategy

Inspired by what human liver enzymes can do, chemists have developed a new set of copper-catalyzed organic synthesis reactions for building and modifying pharmaceuticals and other molecules. The new reactions are expected to be widely used in drug discovery and optimization, as well as in other chemistry-based industries. …read more

First evidence of human occupation in lava tube cave in Saudi Arabia

First evidence of human occupation in lava tube cave in Saudi Arabia

New research has highlighted an area in Arabia that once acted as a key point for cultural exchanges and trades amongst ancient people — and it all took place in vast caves and lava tubes that have remained largely untapped reservoirs of archaeological abundance in Arabia. Through meticulous excavation and analysis, the international team uncovered a wealth of evidence at Umm Jirsan, spanning from the Neolithic to the Chalcolithic/Bronze Age periods (~10,000-3,500 years ago). …read more

Family and media pressure to lose weight in adolescence linked to how people value themselves almost two decades later

Family and media pressure to lose weight in adolescence linked to how people value themselves almost two decades later

People who as teenagers felt pressure to lose weight from family or from the media, females, people who are not heterosexual, and people experiencing socioeconomic disadvantage, are most at risk of ‘internalized’ weight stigma, new research has found. …read more
