Male animals are subject to stronger evolutionary pressures than females
Male animals are subject to stronger selection pressures than females, which may allow populations to adapt to environmental change more efficiently, according to a report published in the open-access journal eLife......»»
Fruit fly helps unlock clues about how organs, tissue and cancer grow
The fruit fly, Drosophila, has been used by scientists for more than 100 years to unravel key features of life on Earth, such as how animals respond to the sun and how the bodies of animals are patterned from head to tail......»»
The first glow-in-the-dark animals may have been ancient corals deep in the ocean
Many animals can glow in the dark. Fireflies famously blink on summer evenings. But most animals that light up are found in the depths of the ocean......»»

Genomic analysis of a species of zooplankton questions assumptions about speciation and gene regulation
When two animals look the same, eat the same, behave the same way, and live in similar environments, one might expect that they belong to the same species......»»
Deer are expanding north, and that"s not good for caribou: Scientists evaluate the reasons why
As the climate changes, animals are doing what they can to adapt. Researchers from UBC Okanagan—which includes partners from Biodiversity Pathways' Wildlife Science Center, the Alberta Biodiversity Monitoring Institute, the University of Alberta, a.....»»
Startup financing gender gaps greater in societies where women are more empowered: Study
Commercial bankers provide capital to fund the operations and growth of businesses. However, as these lenders evaluate entrepreneurs who apply for loans, gender bias leads to women being denied more often than their male counterparts......»»
Half our colleagues suffer pain and discomfort from periods—but they"re still a taboo subject at work

Evolutionary biologists show that the color variants of female cuckoos are based on ancient mutations
Every cuckoo is an adopted child—raised by foster parents, into whose nest the cuckoo mother smuggled her egg. The cuckoo mother is aided in this subterfuge by her resemblance to a bird of prey. There are two variants of female cuckoos: a gray morp.....»»
The story of the first Alor people adapting to climate change 43,000 years ago
As humans, our greatest evolutionary advantage has always been our ability to adapt and innovate. When people first reached the expanded coastline of Southeast Asia around 65,000 years ago, and faced the sea crossings necessary to continue east into.....»»
Scientists use ancient DNA, historical context to unravel kinship, social practices of Avar society
A multidisciplinary research team led by scientists at the Max Planck Institute for Evolutionary Anthropology has combined ancient DNA data with a clear archaeological, anthropological and historical context to reconstruct the social dynamics of Avar.....»»
Bioluminescence first evolved in animals at least 540 million years ago, pushing back previous oldest dated example
Bioluminescence first evolved in animals at least 540 million years ago in a group of marine invertebrates called octocorals, according to the results of a new study from scientists with the Smithsonian's National Museum of Natural History......»»
Tiny rubber spheres used to make a programmable fluid
The spheres collapse under pressure, giving the fluid very unusual properties. Enlarge / At critical pressures, the fluid's spheres become a mixture of different states. (credit: Adel Djellouli/Harvard SEAS) Building a r.....»»
First discovery in decades of blue whales near Seychelles
Blue whales are fascinating animals. At 24–30 meters in length (longer than a basketball court) they are the largest creatures on Earth. They are also among the rarest. Estimates suggest that there are only about 5,000 to 15,000 blue whales left in.....»»

Study uncovers neural mechanisms underlying foraging behavior in freely moving animals
While foraging, animals including humans and monkeys are continuously making decisions about where to search for food and when to move among possible sources of sustenance......»»
Why zebrafish can regenerate damaged heart tissue, while other fish species cannot
A heart attack will leave a permanent scar on a human heart, yet other animals, including some fish and amphibians, can clear cardiac scar tissue and regrow damaged muscle as adults......»»
H5N1 strain of bird flu found in milk: WHO

Wild turkey numbers are falling in some parts of the US—the main reason may be habitat loss
Birdsong is a welcome sign of spring, but robins and cardinals aren't the only birds showing off for breeding season. In many parts of North America, you're likely to encounter male wild turkeys, puffed up like beach balls and with their tails fanned.....»»
Marine microbial populations: Potential sensors of the global change in the ocean
Animal and plant populations have been extensively studied, which has helped to elucidate ecosystem processes and evolutionary adaptations. However, this has not been the case with microbial populations, due to the impossibility of isolating, culturi.....»»
Social media for sex education: South African teens explain how it would help them
Most teenagers dread talking about sex with their parents. Their parents feel the same way. In some societies it's considered taboo to even broach the subject. And, even where sexuality education is taught at schools, research has shown that effectiv.....»»
