IntroductionThis study aimed to evaluate the effects of a single-cell protein (SCP) source from Paecilomyces variotii on the apparent total tract digestibility (ATTD) of macronutrients and energy, diet palatability, fecal fermentative metabolites, and microbiota in dogs.Materials and methodsFive extruded diets containing 0, 4, 8, 12, and 16% of SCP were manufactured. To isolate the metabolizable …

Hibernation is a specialized adaptive energy-saving survival strategy evolved by animals to withstand winter cold stress and food scarcity. Its core feature lies in profound metabolic suppression, characterized by a drastic reduction in metabolic rate during hibernation, accompanied by the coordinated downregulation of multiple physiological functions such as body temperature, heart rate, and res…

Various strains of Escherichia coli are significant foodborne pathogens that can threaten public health through contaminated food. In this study, a total of 217 animal-derived food products, including raw turkey meat, raw beef, fresh cheese, and raw milk, were collected from markets, butcher shops, dairies, and neighborhood markets in Istanbul during 2021, 2022, and 2023. E. coli isolates were de…

Staurogyne stenophylla (Hemsl.) C. B. Clarke ex S. Moore (S. stenophylla) has long been recognized in traditional folk medicine for its anti-inflammatory properties. However, its specific bioactive components and underlying molecular mechanisms remain unclear, which limits its scientific application as a novel anti-inflammatory feed additive for livestock and poultry. This study employed ultra-pe…

A globally distributed genus of boletes called Lanmaoa may represent a third family of psychoactive mushrooms, working through a chemistry that no one understands yet. The genus already holds one of the strangest entries in the toxicological literature. In Yunnan, in southwestern China, eating an undercooked bolete known locally as jian shou qing can bring on vivid hallucinations of tiny people. …

Collagen is often described as the body’s natural scaffolding. It gives strength and structure to skin, bones, tendons, organs, and many other tissues. For decades, biology textbooks have shown collagen as a long, stiff, rod-shaped molecule. But a surprising new study suggests that picture is only part of the story. Researchers at the Center for […] The post Our body’s most abundant protein behav…

I find much to like about house wrens, including their scientific name: Troglodytes aedon.  It's very appropriate for this vigorous singer and cavity nester. Troglodyte is from the Greek for "hole or cave dweller," while aedon, also Greek in ...

Welcome to the world of bees. This fuzzy yellow and black striped fellow is a bumblebee in the genus Bombus sp., family Apidae. We know him from our gardens where we see them busily lapping up nectar and pollen from flowers with their ...

The elements that make up the ink in tattoos travel inside the body in micro and nanoparticle forms and reach the lymph nodes, according to a study published in Scientific Reports on 12 September by scientists from Germany and the ESRF, the European Synchrotron, Grenoble (France). It is the first time researchers have found analytical […]

Male rats that were exposed to the widely used plasticizer di-(2-ethylhexyl) phthalate (DEHP) during early development exhibited increased anxiety behavior as adults, according to a study being presented Saturday at ENDO 2026, the Endocrine Society's annual meeting in Chicago, Ill.

Scientists studying the remarkable regenerative abilities of planarian flatworms have uncovered a previously unknown type of immune cell with an unusually destructive defense strategy. What if an immune cell could wipe out nearby threats by detonating itself? That is exactly what Stanford researchers have discovered in one of nature’s most unlikely creatures: the planarian flatworm. [...]

A new test provides a much more complete picture of DNA than current standard diagnostics and leads to a diagnosis more often. The test can replace 15 other tests, making it faster and more efficient. Researchers from Radboud university medical center recommend in the New England Journal of Medicine that this test be adopted everywhere […]

As AI transforms biology, longevity startups are attracting investors, advancing toward clinical milestones, and reshaping the future of aging research.

Ok so, the parabiosis was a temporary effect, but the answer turned out to be having a blood transfusion with yourself instead. So if this video is right there is a molecule called HMGB1 which can be blocked rather than having said transfusion. Scientists may have identified one of the molecules that helps aging spread […]

Researchers say the mechanics of having sex in space would be easier to manage than the biology of pregnancy and fetal development in a reduced-gravity, high-radiation environment. Read More

Do genes dictate academic success? A new study of European twins shows the answer depends on where you live. Different school systems and family backgrounds can actually change how much a student's natural ability matters in the classroom.

Their findings reveal an extraordinary concentration of whale fossils and carcasses spread across a vast area west of Australia.
