Scientists prove cell-cultured meat products can offer enhanced nutrition compared to conventionally produced meat

Scientists prove cell-cultured meat products can offer enhanced nutrition compared to conventionally produced meat

October 15, 2020by New HarvestA group of researchers at Tufts University have genetically engineered cow muscle cells to produce plant nutrients not natively found in beef cells. Using the same carotenoid pathway exploited in golden rice, they coaxed bovine cells into producing beta carotene—a provitamin usually found in carrots and tomatoes.In doing so, they demonstrated that cell-cultured might be able to surpass the of conventionally farmed meat."Cows don't have any of the genes for producing beta carotene," said Andrew Stout, lead author of the study and Biomedical Engineering Ph.D....

Researchers identify promising model for studying human aging

Researchers identify promising model for studying human aging

January 13, 2021by Hannah Halusker,There are many components to aging, both mental and physical. When it comes to the infrastructure of the human body—the musculoskeletal system that includes muscles, bones, tendons and cartilage—age-associated decline is inevitable, and the rate of that decline increases the older we get. The loss of muscle function—and often muscle mass—is scientifically known as sarcopenia or dynapenia.For adults in their 40s, sarcopenia is hardly noticeable—about 3% is lost each decade. For those aged 65 years and older, however, can become much more rapid, with an...

Promising new antibodies against SARS-CoV-2 found

January 12, 2021byAn international team led by the University of Bonn (Germany) identified and further developed novel antibody fragments against the SARS coronavirus-2. These "nanobodies" are smaller than classic antibodies penetrating the tissue better and can be produced in larger quantities. The researchers also combined the nanobodies into potentially particularly effective molecules attacking different parts of the virus simultaneously. The approach could prevent the pathogen from evading the active agent through mutations. The results appear in Science.Antibodies are an important...

Scientists develop new gene therapy strategy to delay aging

January 8, 2021by Zhang Nannan,Cellular senescence, a state of permanent growth arrest, has emerged as a hallmark and fundamental driver of organismal aging. It is regulated by both genetic and epigenetic factors. Despite a few previously reported aging-associated genes, the identity and roles of additional genes involved in the regulation of human cellular aging remain to be elucidated. Yet, there is a lack of systematic investigation on the intervention of these genes to treat aging and aging-related diseases.How many aging-promoting are there in the ?

New statistical method exponentially increases ability to discover genetic insights

January 8, 2021byPleiotropy analysis, which provides insight on how individual genes result in multiple characteristics, has become increasingly valuable as medicine continues to lean into mining genetics to inform disease treatments. Privacy stipulations, though, make it difficult to perform comprehensive pleiotropy analysis because individual patient data often can't be easily and regularly shared between sites. However, a statistical method called Sum-Share, developed at Penn Medicine, can pull summary information from many different sites to generate significant insights. In a test of...

Study sheds new light on how the brain distinguishes speech from noise

Study sheds new light on how the brain distinguishes speech from noise

December 20, 2020byFor the first time, researchers have provided physiological evidence that a pervasive neuromodulation system—a group of neurons that regulate the functioning of more specialized neurons—strongly influences sound processing in an important auditory region of the brain. The neuromodulator, acetylcholine, may even help the main auditory brain circuitry distinguish speech from noise."While the phenomenon of these modulators' influence has been studied at the level of the neocortex, where the brain's most complex computations occur, it has rarely been studied at the more...
