Their results revealed that women with lower 2D:4D are more likely to be lesbian. Meanwhile, men with higher 2D:4D are more likely to be gay. 'Bisexual women are more similar to heterosexual women in digit ratios, but there may be further nuance,' the researchers explained.

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 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.

Such sex 'distorters' have been discovered - and studied in great depth - in laboratory animals such as mice and flies, in which their effects can be detected through selective breeding. 'If you look, more often than not, you find them,' says Nitin Phadnis, an evolutionary geneticist at the University of Utah in Salt Lake City, who co-led the study.

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.

A virus that sickens marine mammals has been detected in Arctic waters for the first time. Scientists used drones armed with petri dishes to collect samples of blow - the air and mucus whales expel from their blowholes - from whales in northern Norway. The team identified cetacean morbillivirus in samples from humpback whales ( Megaptera novaeangliae) and one sperm whale ( Physeter macrocephalus), though the humpbacks showed no symptoms of disease.
