Judging a fish by its color: For female bluefin killifish, love is a yellow mate
There's an old adage that warns against passing judgment based on appearance, but female bluefin killifish, like many animal species, apparently don't share such human wisdom when choosing a mate. Researchers ...
Unraveling cell division
CRG researchers shed new light on mitosis. The study published in the Journal of Cell Biology describes how Topo 2 disentangles DNA molecules and is essential for proper cell division
Researchers decipher genetic mechanism that makes the midge invulnerable to harsh conditions
New collaborative research published in the journal Nature Communications by scientists from Japan, Russia and the US contains the genetic analysis on a species of African midge, which can survive a wide ...
App helps homeowners identify spiders
Each autumn the number of spiders seen indoors suddenly increases as males go on the hunt for a mate. The Society of Biology is launching a new app to help the public learn more about the spiders that will ...
Global wild tiger population to be counted by 2016
Thirteen countries with wild tiger populations agreed Tuesday to take part in a global count to establish how many of the critically endangered animals are left and improve policies to protect them.
What's for dinner? Rapidly identifying undescribed species in a commercial fungi packet
For lovers of wild foods, autumn harks a season of bounty. Fungi of dizzying variety erupt from wood and soil, luring intrepid collectors to woodlands in search of elusive but delectable wild mushrooms. Part ...
Season's first dolphins killed in Japan, say activists

Scientists given rare glimpse of 350-kilo colossal squid
Scientists said Tuesday a female colossal squid weighing an estimated 350 kilograms (770 lbs) and thought to be only the second intact specimen ever found was carrying eggs when discovered in the Antarctic.
Scientists discover RNA modifications in some unexpected places
The so-called central dogma of molecular biology—that DNA makes RNA which makes protein—has long provided a simplified explanation for how genetic information is deciphered and translated in living organisms.
Scientists discover tropical tree microbiome in Panama
Human skin and gut microbes influence processes from digestion to disease resistance. Despite the fact that tropical forests are the most biodiverse terrestrial ecosystems on the planet, more is known about ...
Collaboration drives achievement in protein structure research
When this week's print issue of the journal Science comes out, a collective cheer will go up from New Mexico, Montana and even the Netherlands, thanks to the type of collaborative effort that is more and more the norm in the ...
Decoding virus-host interactions in the oxygen-starved ocean
For multicellular life—plants and animals—to thrive in the oceans, there must be enough dissolved oxygen in the water. In certain coastal areas, extreme oxygen-starvation produces "dead zones" that decimate ...
Study indicates hunting restrictions for tapirs may not be enough
A published study indicates that lowland tapir populations may continue to drop in French Guiana, despite recent restrictions on hunting. Researchers from the Office National de la Chasse et de la Faune Sauvage in French ...
Cells simply avoid chromosome confusion: Reproductive cell division has a mechanical safeguard against errors
