Around 445 million years ago, Earth underwent a dramatic transformation that reshaped the future of life. In a remarkably short geological period, massive glaciers spread across the southern supercontinent Gondwana. As ice locked up water, vast shallow seas dried out, triggering an “icehouse climate” and radically altering ocean chemistry. The result was catastrophic. Roughly 85% […]

Scientists at the University of Adelaide’s Davies Livestock Research Centre (DLRC) have unveiled the most comprehensive cattle genome ever assembled, a breakthrough expected to improve Wagyu breeding and enhance beef marbling. The research delivers a clearer picture of cattle genetics than any previous reference. “We have presented a near complete cattle genome that is 16 […]

Despite the well-established role of condensin II in mitotic chromosome assembly, its function in interphase chromosome organization remains poorly understood. Here, we applied multiscale FISH techniques to human cell lines engineered for single or double depletion of condensin II and cohesin and examined their functional collaboration at two distinct stages of the cell cycle. Our […]

For roughly 10,000 years, farming communities have improved their crops by saving seeds from plants with the best flavor, size, and toughness. This slow and careful process shaped nearly every fruit and vegetable found in grocery stores today. Most modern crops are the result of centuries or even millennia of selective breeding. Researchers at Cold […]

Scientists studying the Great Salt Lake have identified at least one species of nematode that is completely new to science, with evidence suggesting there may be a second. Researchers from the University of Utah recently published a paper describing the tiny roundworm and formally naming it in a way that honors the Indigenous people whose […]

A large scale genetic analysis of more than 900,000 people has revealed that specific regions of DNA become increasingly unstable over time. These regions are made up of very short sequences that repeat again and again, and the study shows that they tend to grow longer as people age. Researchers also found that common inherited […]

Hundreds of mitochondrial proteins rely on N-terminal presequences for organellar targeting and import. While generally described as positively charged amphiphilic helices, presequences lack a consensus motif and thus likely promote protein import into mitochondria with variable efficiencies. Indeed, the concept of presequence strength underlies biological models such as stress sensing, yet a quantitative analysis of […]

Scientists have, for the first time, rebuilt ancient genomes of Human betaherpesvirus 6A and 6B (HHV-6A/B) using DNA from archaeological human remains that are more than 2,000 years old. The research, led by teams at the University of Vienna and the University of Tartu (Estonia) and published in Science Advances, shows that these viruses have […]
