Polymers jump through hoops on pathway to sustainable materials
Most consumer plastics are blends of linear polymers..
Australian islands home to 414 million pieces of plastic pollution
The study led by IMAS researcher Dr Jennifer Lavers and published in the journal Scientific Reports estimated beaches on the Indian Ocean islands are littered with 238 tonnes of plastic, including 977,000 shoes and 373,000 toothbrushes. Dr Lavers' research made headlines around the world when in May 2017
Brain's insular cortex processes pain and drives learning from pain
We've known for a while that a brain area called amygdala is important for threat learning.
Breakthrough in new material to harness solar power
The University of Toledo physicist pushing the performance of solar cells to levels never before reached made a significant breakthrough in the chemical formula and process to make the new material.
Hummingbird robot uses AI to soon go where drones can't
Your friendly neighborhood hummingbirds.If drones had this combo, they would be able to maneuver better through collapsed buildings and other cluttered spaces to find trapped victims.
Broccoli sprout compound may restore brain chemistry imbalance linked to schizophrenia
They say the results advance the hope that supplementing with broccoli sprout extract, which contains high levels of the chemical sulforaphane, may someday provide a way to lower the doses of traditional antipsychotic medicines needed to manage schizophrenia symptoms, thus reducing unwanted side effects of the medicines. "It's possible that
Paper wasps capable of behavior that resembles logical reasoning
For millennia, transitive inference was considered a hallmark of human deductive powers, a form of logical reasoning used to make inferences: If A is greater than B, and B is greater than C, then A is greater than C. But in recent decades, vertebrate animals including monkeys, birds and fish
Birds outside their comfort zone are more vulnerable to deforestation
Predicting a species' sensitivity to environmental changes, such as deforestation or climate change, is crucial for designing conservation strategies..
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
