New knowledge about our Earth’s most important biochemical reaction: A step towards increasing CO2 uptake in plants

Posted: 17 Nov 2021 06:15 PM PST

A group of proteins in plant cells plays a vastly more important role in regulation of photosynthesis than once thought, according to new research. The research is an important step towards fully understanding photosynthesis regulation and increasing CO2 uptake in plants to benefit the climate.

Brief 5:2 diet advice is as effective as traditional GP advice, but people like it better, according to new study

A clinical trial has found people prefer receiving information on the 5:2 diet than standard GP weight management advice despite both interventions achieving similar modest weight loss results.

Shape-morphing microrobots deliver drugs to cancer cells

Chemotherapy successfully treats many forms of cancer, but the side effects can wreak havoc on the rest of the body. Delivering drugs directly to cancer cells could help reduce these unpleasant symptoms. Now, in a proof-of-concept study, researchers have made fish-shaped microrobots that are guided with magnets to cancer cells, where a pH change triggers them to open their mouths and release their chemotherapy cargo.

Bacteria as climate heroes

Posted: 17 Nov 2021 07:01 AM PST

Acetogens are a group of bacteria that can metabolise formate. For example, they form acetic acid -- an important basic chemical. If these bacteria were manipulated to produce ethanol or lactic acid, a comprehensive circular economy for the greenhouse gas CO2 could be realised. To ensure that the process is sustainable, the CO2 is extracted directly from the air and converted to formate using renewable energy. To find out how exactly formate can be utilised by the Acetobacterium woodii (short: A. woodii), a team led by Stefan Pflügl from the Institute of Chemical, Environmental and Bioscience Engineering at TU Wien investigated how the bacterium metabolises various substrates -- including formate. Furthermore, the researchers used a metabolic model to study how A. woodii could be genetically modified to produce substances other than acetic acid.

There may be more bird species in the tropics than we know

Study of a perky little bird suggests there may be far more avian species in the tropics than those identified so far. After a genetic study of the White-crowned Manakin, scientists say it's not just one species and one of the main drivers of its diversity is the South American landscape and its history of change.

New approach could overcome fungal resistance to current treatments

Posted: 17 Nov 2021 07:00 AM PST

Current medications aren't particularly effective against fungi. The situation is becoming more challenging because these organisms are developing resistance to antimicrobial treatments, just as bacteria are. Now, researchers report that they have identified compounds that tackle these infections in a new way -- by interfering with fungal enzymes required for fatty acid synthesis -- potentially opening the door to better therapies.

A wild strawberry aroma for foods from a fungus growing on fruit waste

Posted: 17 Nov 2021 07:00 AM PST

The wild strawberry is even more highly prized than its store-bought cousin because of its intense aroma and uniquely sweet taste. However, they're hard to find in the wild, so some companies make synthetic versions of this flavor. Now, researchers have come up with a naturally derived wild strawberry aroma by having an edible fungus make it from waste from black currant juice production.
