Ants are among the most familiar insects on Earth today, but their origins remain cloaked in deep evolutionary history. Until now, the oldest known ant specimens came from amber deposits in France and Myanmar, dating to the Cretaceous period around 100 million years ago. But a new discovery—published recently in the journal Current Biology—pushes that timeline back even further. “Our team has discovered a new fossil ant species representing the earliest undisputable [...]

A study researchers suggests that a diet rich in soluble fiber can protect the intestine against pathogenic bacteria. The conclusion is based on experiments with mice exposed to Clostridioides difficile, which causes colon inflammation and diarrhea. "We were able to treat the mice that had an infection with a diet supplemented with soluble fiber. This is digested by intestinal microbiota, which produces compounds such as acetate. This initiates a cascade of interactions that leads to [...]

A new coronavirus feared to be able to spread to humans has been discovered by a China-linked scientist. Researchers from Brazil and colleagues affiliated with the University of Hong Kong detected the new strain after swabbing the mouths and rectums of bats. The novel strain is closely related to MERS — a disease that kills about 35 percent of the people it infects. The virus is now being transported to China, along with six other viruses discovered during the [...]

The findings were based on experiments with rats, which were not obese but exhibited a condition similar to type 2 diabetes, a disease characterized by elevated blood sugar due to reduced action of the hormone insulin. As the authors explain, supplementation with [...]

The most extensive study on how dietary polyphenol consumption affects the risk of cardiometabolic issues monitored over 6,000 Brazilians for eight years. A study of over 6,000 Brazilians—the largest of its kind—found that a diet rich in polyphenol-rich foods such as grapes, strawberries, açaí, oranges, chocolate, wine, and coffee can reduce the risk of metabolic syndrome by up to 23%. The findings, published in the Journal of Nutrition, highlight the protective [...]

Posted on 11/23/2024, 6:20:30 AM by ConservativeMind A study has concluded that the use of monochromatic infrared light in conjunction with conventional physical therapy is a promising alternative for the treatment of peripheral diabetic neuropathy, a type of nerve damage that most often affects the legs and feet, and one of the most frequent, insidious and incapacitating complications of diabetes. Pharmacological treatment is usual in this case, but other therapeutic [...]

High blood pressure (hypertension) causes thickening of the blood vessels and hardening of the arteries (arteriosclerosis). A study has shown that a similar phenomenon occurs in the lungs. High blood pressure hardens the bronchi and increases airway resistance, impairing respiratory capacity. "Our analysis showed that subjects who practiced regular physical activities appeared to be partially protected against hardening of the bronchi," Rodolfo de Paula Vieira. Prior research [...]

In an animal model of Duchenne muscular dystrophy, researchers tested a therapy that combines photobiomodulation using laser light or light-emitting diodes (LEDs) with idebenone, an antioxidant compound investigated for application in neurodegenerative diseases. The strategy prevented muscle degeneration and improved regenerative capacity in the muscle fibers affected by the disease. Duchenne muscular dystrophy is the most common and most severe form of childhood muscular dystrophy and [...]

Aerobic training is known to regulate blood pressure more effectively when practiced in the evening than in the morning. Researchers who conducted a study of elderly patients concluded that evening exercise is better for blood pressure regulation thanks to improved cardiovascular control by the autonomic nervous system via a mechanism known as baroreflex sensitivity. "There are multiple mechanisms to regulate blood pressure, and although morning training was beneficial, only evening [...]
