Mimicking exercise with a pill

Posted by in categories: biotech/medical, chemistry, health, neuroscience

NEW ORLEANS, March 18, 2024 — Doctors have long prescribed exercise to improve and protect health. In the future, a pill may offer some of the same benefits as exercise. Now, researchers report on new compounds that appear capable of mimicking the physical boost of working out — at least within rodent cells. This discovery could lead to a new way to treat muscle atrophy and other medical conditions in people, including heart failure and neurodegenerative disease.

The researchers will present their results today at the spring meeting of the American Chemical Society (ACS). ACS Spring 2024 is a hybrid meeting being held virtually and in person March 17–21; it features nearly 12,000 presentations on a range of science topics.

Startup rolls out revolutionary snack that could set new standard for food: ‘They can be produced in a near-endless variety’

Posted by in category: food

The company’s long-lasting products may even help cut down on discarded food, around a third of which is tossed globally every year.

That waste then releases methane, a powerful heat-trapping gas, as it goes through the process of breaking down in landfills, contributing to rising global temperatures linked to extreme weather events that frequently cause displacement or damage vital food crops.

According to Packaging Digest, even though foodberries are perishable, they are safe and tasty to eat for anywhere from 60 to 90 days, though frozen items can last for more than a year.

Non-invasive blood test shows 83% sensitivity in detecting colorectal cancer, offering hope for early diagnosis

Posted by in category: biotech/medical

In a recent study published in The New England Journal of Medicine, a team of scientists from the United States (U.S.) and Canada evaluated the performance of a blood-based testing method that uses cell-free deoxyribonucleic acid (DNA) to screen for colorectal cancer.

Scientists proved the fundamental limits of electromagnetic energy absorption

Posted by in categories: energy, mathematics

Until recently, researchers were unsure of the minimum thickness of a transparent substance required to take in a given quantity of light.

Konstantin N. Rozanov of the Institute for Theoretical and Applied Electrodynamics in Russia discovered more than two decades ago the amount of light that a gadget might absorb at various wavelengths if one side of it was coated in metal. This metal establishes a barrier where light is absorbed or bounced back, simplifying the mathematical solution.

Ultraviolet Radiation from Massive Stars Shapes Planetary Systems

Posted by in categories: materials, space

Up to a certain point, very luminous stars can have a positive effect on the formation of planets, but from that point on the radiation they emit can cause the material in protoplanetary discs to disperse.

Can gut bacteria help shape newborn’s immune system? Study sheds light

Posted by in categories: biotech/medical, food, health, neuroscience

Researchers from Weill Cornell Medicine have discovered that unique bacteria colonize the gut shortly after birth and make the neurotransmitter serotonin to educate gut immune cells that help in preventing allergic reactions to food and the bacteria themselves during early development.

The study published in the journal Science Immunology on March 15, 2024, revealed that bacteria abundant in the guts of newborns produce serotonin, which promotes the development of immune cells called T-regulatory cells or Tregs. These cells suppress inappropriate immune responses to help prevent autoimmune diseases and dangerous allergic reactions to harmless food items or beneficial gut microbes.

Scientists harness food by-products to fight antimicrobial resistance

Posted by in categories: biotech/medical, food

Scientists are embarking on a £1.1 million project aimed at revolutionising drug production by using food by-products to develop new antimicrobial drugs.

Led by the University of Strathclyde in collaboration with the University of Surrey and GSK, the research endeavours to make antimicrobial production more cost-effective and sustainable, thereby addressing the pressing global challenge of antimicrobial resistance.

The project seeks to leverage bacteria, particularly Streptomyces, known for their potential to produce various drugs including antimicrobials. By harnessing food by-products, the team is aiming to device a less carbon-intensive process for biomanufacturing, which could pave the way for a range of medications including anti-parasitic, anti-cancer, anti-fungal, and immunosuppressant drugs.
