Study finds tuna traits evolved slowly after asteroid

A new study shows that tunas and their relatives did not gain large size and warm-bloodedness immediately after the asteroid strike 66 million years ago. Traits evolved independently in different lines over many millions of years.

Experimental drug protects hearts in Duchenne muscular dystrophy

A new study found that the experimental drug Setanaxib preserved heart function and reduced scarring in preclinical models of Duchenne muscular dystrophy, and identified the enzyme NOX4 as a possible treatment target.

New liver cell linked to MASH and a gene called Themis

Researchers found a new type of liver cell that appears in MASH, a severe form of MASLD. Themis gene activity was high in diseased livers, and mouse tests show the THEMIS pathway may affect liver damage.

Gene Dec2 helps pancreatic cancer hide from immune cells

Researchers found that the gene Dec2 can disguise pancreatic cancer cells and that Dec2 levels change during the day. The study may help improve immunotherapy, vaccines and new treatment timing for this disease.

Chickens changed to keep useful genes in eggs

University of Missouri researchers used gene editing to place a new segment at a specific spot in the chicken genome. The change stayed active in cells and could help make eggs that contain medical proteins.

Vitamin D may slow diabetes for some people

A new analysis of a large US trial suggests vitamin D supplements might delay progression from prediabetes to type 2 diabetes for people with certain vitamin D receptor gene variations. Researchers warn against taking high doses without medical advice.

How the Amazon molly stays genetically healthy

Researchers at the University of Missouri found that the all-female Amazon molly keeps its DNA healthy despite cloning. They show gene conversion and genome comparisons help explain how the species avoided extinction and remained diverse.

Blood test in dogs may predict lymphoma response

Researchers studied blood samples from dogs with diffuse large B-cell lymphoma and found gene activity patterns that can predict treatment response. A simple blood test may help guide treatment choices in dogs and possibly humans.

Blood piRNAs predict short-term survival in older adults

A study led by Duke Health found that small RNA molecules called piRNAs in blood can predict two-year survival for people aged 71 and older. A simple blood test may help identify short-term risk.

Hidden vertebrate species may double known numbers

A new study suggests many vertebrate species are “cryptic”: they look the same but have distinct DNA. On average there may be two hidden species for each recognized one, which can affect conservation and legal protection.

More precise DNA editing could help cystic fibrosis

Researchers refined a DNA base-editing tool to make it more precise. The advance may improve treatment for some cystic fibrosis mutations and make genetic therapies safer, but the work is still at an early preclinical stage.

Study of probiotic yeast behaviour in the gut

Researchers examined how the probiotic yeast Saccharomyces boulardii acts in the gut to guide future drug delivery. They measured yeast gene activity in germ‑free mice and found gut‑active promoters and signs of safety.

Sickle cell disease and costly new treatments

Many African countries have a high burden of sickle cell disease. Uganda now screens newborns for free, while new gene therapies are approved in rich countries but remain too expensive for most people in Africa.
