The origins of language | ScienceDaily

Chimpanzees are capable of complex communication: The human capacity for language may not be as unique as previously thought. Chimpanzees have a complex communication system that allows them to combine calls to create new meanings, similar to human language. Combining calls creatively: Chimpanzees use four ways to change meaning when combining single calls into two-call […]

First fossil evidence of endangered tropical tree discovered

For the first time, scientists have discovered fossil evidence of an endangered, living tropical tree species. The unprecedented find was made in Brunei, a country on the large island of Borneo, and reveals a critical piece of the ancient history of Asia’s rainforests, highlighting the urgent need for conservation in the region, according to researchers […]

AI-designed DNA controls genes in healthy mammalian cells for first time

A study published today in the journal Cell marks the first reported instance of generative AI designing synthetic molecules that can successfully control gene expression in healthy mammalian cells. Researchers at the Centre for Genomic Regulation (CRG) created an AI tool which dreams up DNA regulatory sequences not seen before in nature. The model can […]

Triassic fossil reveals nature’s best jaw for hunting fast fish

The best jaw for hunting fast fish is long and full of sharp teeth. This makes sense to us, but it also makes sense in nature: New fossil evidence from Virginia Tech geoscientists revealed that different species of predatory fish independently evolved similar jaw structure hundreds of millions of years apart. “The same evolutionary problem […]

Two new crocodile species discovered

McGill University researchers, in collaboration with Mexican scientists, have discovered two previously unknown species of crocodiles, one living on the island of Cozumel and the other on the atoll of Banco Chinchorro, both off the Yucatán Peninsula. The findings challenge long-held assumptions about the American crocodile (Crocodylus acutus) and highlight the urgent need for conservation […]

Traditional forest medicinal plant ghost pipe used differently today

Despite a long history of traditional medicinal use in the United States, the collection, consumption and efficacy of the peculiar forest plant aptly named ghost pipe, scientific name Monotropa uniflora, remains a mystery. Now, with social media and the internet driving a resurgence in the harvest and economic trade of the parasitic species — which […]

Evaluation of Biofilm Forming Potential and Antimicrobial…

Pseudomonas aeruginosa and Staphylococcus aureus are prominent pathogens responsible for device-associated infections that pose a significant challenge in clinical management. The biofilm-forming ability of these bacteria is a major factor contributing to treatment failures and the recurrence of infections. This study was conducted to evaluate the biofilm production potential of these bacteria isolated from urinary […]

Why did some ancient animals fossilize while others vanished?

Why do some ancient animals become fossils while others disappear without a trace? A new study from the University of Lausanne, published in Nature Communications, reveals that part of the answer lies in the body itself. The research shows that an animal’s size and chemical makeup can play an important role in determining whether it’s […]

A coordinated kinase and phosphatase network regulates Stu2 recruitment to yeast kinetochores

Cells coordinate diverse events at anaphase onset, including separase activation, cohesin cleavage, chromosome separation, and spindle reorganization. Regulation of the XMAP215 family member and microtubule polymerase, Stu2, at the metaphase-anaphase transition determines a redistribution from kinetochores to spindle microtubules. We show that cells modulate Stu2 kinetochore-microtubule localization by Polo-like kinase1/Cdc5-mediated phosphorylation of T866, near the […]
