New research shows 8,000-pound sloths once dug caves, adapted to oceans, and roamed widely—until climate and humans brought their downfall. (Artist's concept.) Credit: SciTechDaily.com
Long before they became tree-hugging symbols of chill, sloths were 8,000-pound giants that roamed deserts, dug caves into cliffs, and even swam like manatees.
Scientists have now pieced together the epic story of their evolution, [...]

Monstrous “Hell Ant” That Thrived 113 Million Years Ago Revealed in Oldest Fossil of Its Kind Ever Discovered
Publicado em 26 abril 2025Ants 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 [...]ver notícia -
Fiber consumption protects gut from serious bacterial infection, study suggests
Publicado em 12 abril 2025A 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 [...]ver notícia -
Pandemic fears as NEW coronavirus is discovered in bats by China-linked scientist(We are all going to die...)
Publicado emA 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 [...]ver notícia -
Consumption of omega-3 weakens insulin resistance in non-obese rats, study shows
Publicado emSkip to comments. Posted on 3/6/2025, 4:20:41 AM by ConservativeMind A study suggests that fish oil can weaken insulin resistance and reduce glucose intolerance by modulating the body's inflammatory response. 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 [...]ver notícia -
Chocolate, Coffee, and Wine Could Slash Your Risk of Metabolic Syndrome
Publicado em 28 fevereiro 2025The 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 [...]ver notícia -
Light-based therapy reduces pain associated with peripheral diabetic neuropathy, study concludes (Red light @ 890 nm)
Publicado em 23 novembro 2024Skip to comments. 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 [...]ver notícia -
High blood pressure reduces respiratory capacity due to hardening of bronchi, study shows
Publicado em 19 outubro 2024High 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 [...]ver notícia -
Study finds LED therapy and antioxidant drug benefit muscle regeneration in Duchenne muscular dystrophy
Publicado em 24 junho 2024In 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 [...]ver notícia -
Study shows aerobic exercise performed in the evening benefits elderly hypertensives more than morning exercise
Publicado em 24 maio 2024Aerobic 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 [...]ver notícia
