Phys.org / Novel bacteria discovered in Florida's stranded pygmy sperm whales

Pygmy sperm whales (Kogia breviceps) are among the ocean's most enigmatic inhabitants—rarely seen and largely unstudied. They live far offshore in small groups, diving in search of squid and fish. Their quiet behavior and ...

Phys.org / Particles don't always go with the flow (and why that matters)

It is commonly assumed that tiny particles just go with the flow as they make their way through soil, biological tissue, and other complex materials. But a team of Yale researchers led by Professor Amir Pahlavan shows that ...

Phys.org / Global study finds smaller fish and shifting food webs despite stable species numbers

Species numbers alone do not fully capture how ecosystems are changing. In a global study, scientists analyzed long-term data from nearly 15,000 marine and freshwater fish communities. They found that fish food webs have ...

Phys.org / Social pressure forces baby clownfish to lose their bars faster, study shows

Growing up, you probably changed your style based on your social influences. It turns out, such pressures affect the appearance of young clownfish (anemonefish) too. A new study from the Okinawa Institute of Science and Technology ...

Phys.org / Uncovering evolution at the center of cell division

Centromeres play virtually the same central role across the entire tree of life: They ensure the faithful segregation of chromosomes during cell division. Yet the striking diversity in centromere architecture—from large, ...

Phys.org / A new method to decode how DNA 'switches' control gene activity

DNA is the blueprint of life. Genes encode proteins and serve as the body's basic components. However, building a functioning organism also requires precise instructions about when, where, and how much those components should ...

Phys.org / Expands the genetic alphabet: Artificial DNA base pair uses halogen bonds to form stable structures

For the first time, researchers have succeeded in developing an artificial DNA base pair that is based on a different chemical force than natural genetic material. While the common natural DNA building blocks are held together ...

Phys.org / Female meiosis in plants can be directly observed with new method

A research team at the IPK Leibniz Institute has developed a method that enables the detailed observation of female meiosis—the process by which germ cells are formed—in the model plant Arabidopsis thaliana. The FeM-ID ...
