Human remains found on Bay Area beaches in 1999 and 2023 have been identified as those of Walter Karl Kinney, a banker who disappeared in 1999. The remains were discovered by a family searching for sea shells in 2022, leading to an investigation that linked the remains to Kinney's family through DNA analysis.

Every state now has a legal avenue where people can request DNA testing of evidence after being convicted. But in many cases, it's not clear if those statutes apply once convicts have died, said Brandon Garrett, a law professor at Duke University.

It was another detail that the rest of the family apparently knew but had never told me; they thought I already knew. The biology mattered less to me than the secret. Dad had been adopted, it turned out. A classic affliction of the 1950s, in which young, unmarried couples were forced to give away their newborn babies.

Scientists have long known that vast colonies of bacteria, viruses and other microorganisms—a population collectively called the microbiome—live on and inside the human body. But how they influenced our health was long a mystery. In just the past few years, we've learned that myriad factors, from the food that we consume to the amount of time that we spend sleeping to our genes to our home, all affect our microbiome.

When I was 4 years old, my parents divorced, and my father moved away. I grew up thinking that my biological father was "John," but recently discovered that my mother had an affair with another man, "Allen." Allen is my biological father. This was a surprise and filled with a lot of drama, but it's gotten weirder than you'd imagine.

Gardaí investigating the murder of Michael Gaine on his farm in Co Kerry almost a year ago are putting "enormous effort" into solving the crime, with hopes pinned on crime scene analysis by US forensic experts returning positive leads.

Scientists in the laboratory of Rendong Yang, PhD, associate professor of Urology, have developed a new large language model that can interpret transcriptomic data in cancer cell lines more accurately than conventional approaches, as detailed in a recent study published in Nature Communications. Long-read RNA sequencing technologies have transformed transcriptomics research by detecting complex RNA splicing and gene fusion events that have often been missed by conventional short-read RNA-sequencing methods.

Targeting genetic screening for the condition to priority areas could help identify at-risk individuals earlier and avoid future health complications, experts say. Haemochromatosis symptoms can evolve over decades as high iron levels in the body cause damage to organs. Early diagnosis and treatment - such as regular blood donation to reduce iron levels - is key to prevent liver damage, liver cancer and arthritis.

Biology is undergoing a transformation. After centuries of studying life as it evolves naturally, researchers are now using a combination of computation and genome engineering to intervene, generating new proteins and even whole bacteria from scratch. The use of artificial-intelligence tools to design biological components, an approach known as generative biology, is set to turbocharge this area of research. Just last year, scientists used AI-assisted design to produce artificial genes that can be expressed in mammalian cells.

Martschenko's argument is largely that genetic research and data have almost always been used thus far as a justification to further entrench extant social inequalities. But we know the solutions to many of the injustices in our world-trying to lift people out of poverty, for example-and we certainly don't need more genetic research to implement them. Trejo's point is largely that more information is generally better than less.

Investigative genetic genealogists are asking for the public's help to identify a child whose skull was seized from a Seabrook, N.H., business more than 30 years ago. The DNA Doe Project, a California-based nonprofit that builds DNA profiles from unidentified human remains, released a new facial reconstruction on Monday. The group also announced that the skull - believed to belong to a girl between the ages of 7 and 9 - has ancestral roots on the Greek island of Chios.

New research published today in Nature dates the boneschipped out from a cave called Grotte a Hominides and nearby it over decadesto about 773,000 years ago, during the era of the last common ancestor of Homo sapiens, Homo neanderthalensis and Denisovans (a group of humans that ranged across Asia and that does not have an agreed-upon species name). We can say that the shared ancestry between these three species is perhaps in Grotte a Hominides in Casablanca, says study co-author Abderrahim Mohib, a prehistorian at the National Institute of Archaeology and Heritage Sciences in Rabat, Morocco.

Called AlphaGenome, the model could help scientists discover why subtle differences in our DNA put us at risk of conditions such as high blood pressure, dementia and obesity. It could also dramatically accelerate our understanding of genetic diseases and cancer. The developers of the model acknowledge it's not perfect, but experts have described it as "an incredible feat" and "a major milestone".
