Protein controls fat metabolism
03/04/2020 - A protein in the cell envelope influences the rate of fatty acid uptake in cells. This process also appears to be altered in overweight people.
A new mechanism triggering cell death and inflammation: A left turn that kills
03/04/2020 - Researchers describe their discovery of a new mechanism that could contribute to the pathogenesis of inflammatory diseases. The scientists found that ZBP1, a protein best known for defending against...
Too much sugar leads to early death, but not due to obesity
03/04/2020 - Sugar-rich diets have a negative impact on health independent of obesity. Researchers discovered that the shortened survival of fruit flies fed a sugar-rich diet is not the result of their...
Too much salt weakens the immune system
02/04/2020 - A high-salt diet is not only bad for one's blood pressure, but also for the immune system. Mice fed a high-salt diet were found to suffer from much more severe bacterial infections. Human...
Lower-sodium turkey breast wins sensory test over full-salt option
02/04/2020 - Food scientists produced a lower-salt processed turkey that consumers in a blind sensory test preferred to a full-salt version, according to a new study.
Scientists program cells to carry out gene-guided construction projects
25/03/2020 - Researchers developed a technique called genetically targeted chemical assembly, or GTCA, which they used to assemble electronically active biopolymer meshes on mammalian brain cells and on neurons...
The ink of the future in printed electronics
25/03/2020 - A research group has created an organic material with superb conductivity that doesn't need to be doped. They have achieved this by mixing two polymers with different properties.
Ball-and-chain inactivation of ion channels visualized by cryo-electron microscopy
25/03/2020 - Ion channels, which allow potassium and sodium ions to flow in and out of cells, are crucial in neuronal 'firing' in the central nervous system and for brain and heart function. These...
Cough that spreads tuberculosis has pain-linked trigger
25/03/2020 - Researchers have pinpointed a molecule that the tuberculosis bacterium manufactures to induce the coughing that spreads the disease by triggering a pain-receptor response. Their findings illustrate...
Polymers to the rescue! Saving cells from damaging ice
26/02/2020 - Chemists provide the foundation to design efficient polymers that can prevent the growth of ice that damages cells.
How low oxygen levels in the heart predispose people to cardiac arrhythmias
26/02/2020 - Low oxygen levels in the heart have long been known to produce life-threatening arrhythmias, even sudden death. Until now, it was not clear how. New findings reveal the underlying mechanism for this...
New study debunks notion that salt consumption contributes to weight loss
26/02/2020 - Researchers found that reducing sodium intake in adults with elevated blood pressure or hypertension decreased thirst, urine volume and blood pressure, but did not affect metabolic energy needs....
Glutamate in the brain has unexpected qualities, researchers show with new analysis method
26/02/2020 - Researchers have achieved something long thought almost impossible -- counting the molecules of the neurotransmitter glutamate released when a signal is transferred between two brain cells. With a...
Leviathan polymer brush made with E. coli holds bacteria at bay
15/01/2020 - A lab accident produced a monster of a polymer brush, an emerging biocompatible material that staves off bacteria while coating and lubricating.
'Bilingual' molecule connects two basic codes for life
15/01/2020 - The nucleic acids of DNA encode genetic information, while the amino acids of proteins contain the code to turn that information into structures and functions. Together, they provide the two...
Saccharin derivatives give cancer cells a not-so-sweet surprise
09/01/2020 - Saccharin received a bad rap after studies in the 1970s linked consumption of large amounts of the artificial sweetener to bladder cancer in laboratory rats. Later, research revealed that these...
An atomic view of the trigger for the heartbeat
09/01/2020 - Tiny pores in heart cells generate electrical signals to initiate each heart beat. Structural studies of these channels provide details on their functions, and also on their malfunction due to...
Creating switchable plasmons in plastics
09/01/2020 - Researchers have developed optical nanoantennas made from a conducting polymer. The antennas can be switched on and off, and will make possible a completely new type of controllable nano-optical...
Betrayed by bile: Bile acids help norovirus sneak into cells
08/01/2020 - Human noroviruses, the leading viral cause of foodborne illness and acute diarrhea around the world, infect cells of the small intestine by piggybacking on a normal cellular process called...
Microbes from humics lakes surprise – bacteria and algae produced omega-3 fatty acids from microplastics
08/01/2020 - The environmental fate of microplastics has been difficult to trace. A research group used carbon isotope labeling to follow the fate of polyethylene in the food chain. To the researchers surprise,...
