Where have all the right whales gone?

Marine researchers have mapped the density of one of the most endangered large whale species worldwide, the North Atlantic right whale, using new data to help avoid right whales’ harmful exposure to commercial fisheries and vessel strikes. The resultin…

Bonobos are more aggressive than previously thought

Chimpanzees and bonobos are often thought to reflect two different sides of human nature — the conflict-ready chimpanzee versus the peaceful bonobo — but a new study shows that, within their own communities, male bonobos are more frequently aggressiv…

How seaweed became multicellular

A deep dive into macroalgae genetics has uncovered the genetic underpinnings that enabled macroalgae, or ‘seaweed,’ to evolve multicellularity. Three lineages of macroalgae developed multicellularity independently and during very different time periods…

Innovative antiviral defense with new CRISPR tool

The rise of RNA viruses like SARS-CoV-2 highlights the need for new ways to fight them. RNA-targeting tools like CRISPR/Cas13 are powerful but inefficient in the cytoplasm of cells, where many RNA viruses replicate. Scientists have devised a solution: …

Exoplanets true to size

A star’s magnetic field must be considered in order to correctly determine the characteristics of exoplanets from observations by space telescopes such as Kepler, James Webb, or PLATO. Researchers show that the distribution of the star’s brightness ove…

Melanomas resist drugs by ‘breaking’ genes

A study has disentangled the mechanisms behind one of the ways melanoma cancer cells develop resistance to treatment. The study found that, in response to some drugs, melanomas can ‘break’ parts of their BRAF gene, which is mutated in 1 in 2 melanomas….

Cells putting on a face

Neural crest cells — embryonic pluripotent cells within the facial primordium — may be necessary for forming proper animal facial structures. Researchers have produced neural crest cell-rich aggregates from human pluripotent stem cells and developed …
