Genomic study offers hope for endangered Oriental stork
A new genomic study of the endangered Oriental stork reveals that the population's genetic health is still surprisingly strong, with high genetic diversity and low levels of inbreeding. This is an uncommon finding in most endangered species populatio.....»»
How plants compete for light: Researchers discover new mechanism in shade avoidance
Plants that are close together do everything they can to intercept light. This "shade avoidance" response has been extensively researched. It is therefore even more remarkable that researchers from the laboratory of Molecular Biology at Wageningen Un.....»»
Betelgeuse Betelgeuse? Bright star Betelgeuse likely has a "Betelbuddy" stellar companion
One of the brightest stars in the night sky, Betelgeuse, may not be on the brink of exploding as a supernova, according to a new study of the star's brightening and dimming. Instead, recent research shows that the observed pulsing of the starlight is.....»»
Understanding the relationship between food waste, climate change and an aging population
Producing food and getting it to people's plates entails a significant expenditure of energy and resources. Unfortunately, approximately one third of all food produced globally is not consumed and discarded. Hence, to build sustainable societies, it.....»»
Astronomers explore the properties of an obscured hyperluminous quasar

Male stalk-eyed flies with short eyestalks are less attractive to females but fight more fiercely, scientists discover
In stalk-eyed flies, longer eyestalks attract the ladies. Females prefer males with longer eyestalks, and other males are less likely to fight them for access to females. But some males have a copy of the X chromosome which always causes short eyesta.....»»
Scientists find southern killer whales of the Pacific have access to enough food, deepening mystery of their struggles
A pair of marine mammal scientists at The University of British Columbia, has found that claims that a lack of access to salmon is what is driving the crash in population numbers for southern resident killer whales of the Pacific are wrong......»»

Cellular senescence research identifies key enzyme to promote healthy aging
A team at Kumamoto University has made a discovery that could help promote healthy aging. As the world's population ages, Japan's aging population in particular is growing at an unprecedented rate, making it crucial to extend healthy lifespans rather.....»»
American lobster population and habitat preferences shifting, study finds
American lobsters along Maine's coast have relocated to new habitats, while the population simultaneously shrunk in abundance and grew older, according to a new study by University of Maine researchers......»»
Physicists show that neutron stars may be shrouded in clouds of axions
A team of physicists from the universities of Amsterdam, Princeton and Oxford have shown that extremely light particles known as axions may occur in large clouds around neutron stars. These axions could form an explanation for the elusive dark matter.....»»
Bumblebee queens choose to hibernate in pesticide-contaminated soil, scientists discover
An alarming discovery from University of Guelph researchers raises concerns for bumblebee health, survival and reproduction. U of G environmental sciences researchers Drs. Nigel Raine and Sabrina Rondeau have found that bumblebee queens are more like.....»»

DNA-binding C2H2 zinc finger proteins also regulate RNA processing, researchers discover
Researchers at the University of Toronto have shown that an important class of DNA-binding factors can also bind to RNA, regulating gene expression through various mechanisms. The study significantly expands our understanding of these proteins' funct.....»»
Environmental DNA and epidemics in wood frogs: Collaboration examines eDNA"s precision in population size estimation
Tracy Rittenhouse, associate professor of natural resources and the environment in UConn's College of Agriculture, Health and Natural Resources (CAHNR), was doing an experiment to study ranavirus epidemics in wood frogs. When Meghan Parsley, then a P.....»»
Astronomers detect ancient lonely quasars with murky origins
A quasar is the extremely bright core of a galaxy that hosts an active supermassive black hole at its center. As the black hole draws in surrounding gas and dust, it blasts out an enormous amount of energy, making quasars some of the brightest object.....»»
Second exoplanet detected orbiting an early G-type star
Astronomers report the detection of a second exoplanet orbiting a G-type star known as TIC 393818343, located some 300 light years away. The newfound alien world is about three times less massive than Jupiter. The finding was detailed in a research p.....»»
