Dexterous herring gulls learn new tricks to adapt their feeding habits
The gulls (Larus argentatus) of Dún Laoghaire Marina at Dublin in Ireland have found a novel way of disposing of the tightly fixed outer layer of sea squirts -- an organism which they have learnt to pluck from the underside of pontoons by diving or floating on the water.
Just one-third of the world's longest rivers remain free-flowing
A team of 34 international researchers from McGill University, World Wildlife Fund (WWF), and other institutions assessed the connectivity status of 12 million kilometers (~7.5 million miles) of rivers worldwide, providing the first-ever global assessment of the location and extent of the planet's remaining free-flowing rivers. Among other findings,
Discovery may lead to new materials for next-generation data storage
A team of researchers led by Cornell University and the University of California Berkeley made a discovery that opens up a plethora of materials systems and physical phenomena that can now be explored.
The scientists observed what's known as chirality for the first time in polar skyrmions in an exquisitely
Oldest known trees in eastern North America documented
David Stahle, Distinguished Professor of geosciences, along with colleagues from the university's Ancient Bald Cypress Consortium and other conservation groups, discovered the trees in 2017 in a forested wetland preserve along the Black River south of Raleigh, North Carolina. Stahle documented the age of the trees using dendrochronology, the study
Antarctic biodiversity hotspots exist wherever penguins and seals poop
Researchers braved the wicked cold of the Antarctic and maneuvered through fields of animal waste and groups of clamoring elephant seals, gentoo, chinstrap, and Adélie penguins to examine the soils and plants surrounding these colonies. "What we see is that the poo produced by seals and penguins partly evaporates
A genomic tour-de-force reveals the last 5,000 years of horse history
The findings identify two new horse lineages that are now extinct and suggest that familiar traits such as speed were only selected for more recently in their history
A comprehensive map of how Alzheimer's affects the brain: Analysis of genes altered by the disease could provide targets for new treatments
This analysis could offer many potential new drug targets for Alzheimer's, which afflicts more than 5 million people in the United States.
Human influence on global droughts goes back 100 years, NASA study finds
The study, published in the journal Nature, compared predicted and real-world soil moisture data to look for human influences on global drought patterns in the 20th century.
Radical desalination approach may disrupt the water industry
If hypersaline brines are improperly managed, they can pollute both surface and groundwater resources.
Magnets can help AI get closer to the efficiency of the human brain: New brain-like networks could help robots approach human-like efficiency at object recognition tasks
Purdue University researchers and experts in brain-inspired computing think part of the answer may be found in magnets..
Nature's dangerous decline 'unprecedented,' species extinction rates 'accelerating'
"The overwhelming evidence of the IPBES Global Assessment, from a wide range of different fields of knowledge, presents an ominous picture," said IPBES Chair, Sir Robert Watson.
Plastic gets a do-over: Breakthrough discovery recycles plastic from the inside out: Scientists have made a next-generation plastic that can be recycled again and again into new materials of any color, shape, or form
Now a team of researchers at the U.S.
Why you love coffee and beer
Scientist Marilyn Cornelis searched for variations in our taste genes that could explain our beverage preferences, because understanding those preferences could indicate ways to intervene in people's diets. To Cornelis' surprise, her new Northwestern Medicine study showed taste preferences for bitter or sweet beverages aren't based on variations in our
Stickier than expected: Hydrogen binds to graphene in 10 femtoseconds: Bound for only ten quadrillionths of a second
The international research team bombarded graphene with hydrogen atoms.
