New survey hints at exotic origin for the Cold Spot

A new survey of galaxy redshifts finds no evidence of a supervoid causing the Cosmic Microwave Background's Cold Spot. The researchers suggest that smaller voids and galaxy clusters in the area may be responsible, but simulations of standard cosmology give only a 1-in-50 chance that the spot arose by chance.

One step closer to an 'exercise pill'

Researchers discovered that inhibiting myostatin production in mice significantly enhances muscle mass and improves markers of heart and kidney health. The findings suggest a promising pathway for protecting against obesity-derived cardiometabolic dysfunction, potentially leading to the development of an 'exercise pill'.

Study: Early organic carbon got deep burial in mantle

A Rice University study found that fossilized organic carbon could have been deeply buried in the mantle starting around 2.4 billion years ago, during a critical period known as the great oxidation event. The researchers discovered that the chemical composition of subducting crustal rock plays a crucial role in determining whether carb...

Gut bacteria tell the brain what animals should eat

A study published in PLOS Biology reveals that gut bacteria control food preferences in fruit flies by inducing metabolic changes that mimic protein satiety. The research identifies two bacterial species responsible for altering appetite behavior, shedding light on the complex interaction between diet and microbes.

More patients can avoid hospital admissions after emergency room visits for diverticulitis

A recent study published in the Journal of the American College of Surgeons found that most patients with uncomplicated diverticulitis can safely go home with a prescription for oral antibiotics after their ER visit. The study, which evaluated 240 patients, revealed that about half of those admitted to hospital could have been sent home.

UTHealth School of Public Health researchers find cold weather linked to mortality risks in Texas

Researchers at UTHealth School of Public Health found that cold temperatures significantly increase mortality risk in Texas, with a 5% increase in deaths per degree Celsius drop in winter. The study focused on 12 metropolitan areas and found that people with pre-existing heart and respiratory diseases are most vulnerable to cold weather.

Bad feelings can motivate cancer patients

A recent study found that anger and guilt in cancer patients can inspire them to set new goals and engage in moderate-to-vigorous exercise. This motivation can counteract the negative effects of stress hormones on physical health. The research suggests that certain negative emotions can play a crucial role in directing adaptive health ...

Model for multivalley polaritons

IBS scientists developed a theoretical model for valv polarization in microcavities, which predicts that valleys with opposite polarization can be distinguished and tuned. This could lead to applications in valleytronics by selectively exciting different valleys with polarized laser light.
