For more than a century, the Natural History Museum of Los Angeles County has exhibited exotic specimens from around the world. But recently that global focus has shifted, as biologists recognize that LA itself is among the planet’s most diverse ecosystems. A new Urban Nature Research Center is enlisting citizen scientists to catalog species that they find in their backyards, from spiders to squirrels. Their goal is to better understand how biodiversity is affected by urbanization and glob ...read more
High HDL levels don’t always mean a lower risk of heart attack.
Open the freezer in the laboratory across the hall from Annabelle Rodriguez’s office at the University of Connecticut Health Center, and you will find rows of miniature fluid-filled vials, many of them holding tiny strands of DNA. For the past 13 years, Rodriguez, a physician-scientist in the university’s Center for Vascular Biology, has kept her eye on one particular gene in those DNA strands that is integral ...read more
At the meeting, Patel, Prince and Saxena made a strong case that there was enough scientific evidence and enough need for discussion that a special issue on mental illnesses was warranted. Horton agreed. “My feeling was the time had come,” he recalls. “Global mental health was totally ignored. It was very clear we needed to jump in and seize this opportunity.”
Still, while they had an idea of the global impact of mental disorders, in 2005 research on diagnosis and treatme ...read more
River floods can have a huge impact on the surrounding lands. Overflows can be harmful not just to local wildlife populations, but to human communities across the globe. Effects from climate change are on the rise, making it more important than ever to understand changes in seasonal flooding patterns. A study recently published in Science looked at data from more than 4,200 observational hydrometric stations in Europe over the past 50 years, and picked out some noticeable patterns. For example, ...read more
Society has long misunderstood these spineless swimmers. Now they could unlock the keys to regeneration.
Hiroshima’s downtown is a garden of modern architecture interspersed with swaths of lovely green parks. In the center is a single structure, in ruins, capped by a skeleton of curved iron. This is the Atomic Bomb Dome, located at the destruction’s epicenter, the sole building that managed to remain standing amid the massive force that flattened everything else for miles in all ...read more

If you want to teach your children the alphabet while mildly traumatizing them at the same time, look no further than “The Gashlycrumb Tinies.” In alphabetical order, and with a jaunty rhyme scheme, 26 children meet fates both gruesome and preposterous. In the future, though, as climate change warms the planet beyond our comfort zone in many regions, the book could be rewritten by adding some heat.
There are 27 ways that a h ...read more

The content you see on the internet is increasingly becoming tailored to you: Music based on your favorite jams, shopping suggestions corresponding to your recent purchases, and television shows similar to your most beloved episodes.
These “similarity searches” drive custom content, and they’re pretty tricky to do correctly and quickly.

That is, for computers at least. Fruit flies, on the other hand, seem to be pretty ...read more

One if by land, two if by sea…if only the debate about how the first humans arrived in the Americas was as easy to sort out as Paul Revere’s fabled lantern signal. Maybe it is. A new study from a different field offers indirect support to researchers advocating a coa ...read more

When the crested pigeon of Australia flees potential foes, it can raise an alarm — not by calling out vocally, but with whistling feathers in its wings. These new findings may be the first proof of an idea Darwin proposed nearly 150 years ago suggesting that birds could use feathers as musical instruments for communication.
Birds are known for the songs they can sing, but many can also generate unusual noises with their feathers. Darwin ...read more
