Scientists untangle the challenging complexities of radiocarbon in ice cores
ANSTO scientists, Dr. Andrew Smith, Dr. Quan Hua and Dr. Bin Yang have contributed to a paper that elucidates how in situ cosmogenic radiocarbon (14C) is produced, retained and lost in the top layer of compacting snow (the "firn layer") and the shall.....»»
Team develops promising new form of antibiotic that makes bacterial cells self-destruct
To address the global threat of antibiotic resistance, scientists are on the hunt for new ways to sneak past a bacterial cell's defense system. Taking what they learned from a previous study on cancer, researchers from the University of Toronto (U of.....»»
Lignin molecular property discovery could help turn trees into affordable, greener industrial chemicals
Trees are the most abundant natural resource living on Earth's land masses, and North Carolina State University scientists and engineers are making headway in finding ways to use them as sustainable, environmentally benign alternatives to producing i.....»»
Molecular "cut and sew" process could accelerate drug design
A innovative molecular "cut and sew" process by University of Dundee scientists has allowed the design of a research tool that will accelerate drug design for diseases for which no other options exist, including cancer......»»
Could injecting diamond dust into the atmosphere help cool the planet?
A multi-institutional team of climatologists, meteorologists and Earth scientists has found evidence that dropping diamond dust from an airplane into the atmosphere could cool the planet. In their study published in the journal Geophysical Research L.....»»
Scientists identify potential deep-ocean greenhouse gas storage solution
As the planet continues to warm and the ramifications of human-driven climate change continue to amplify, the need to find ways to mitigate climate change is growing. In Nature Communications, University of California, Irvine scientists describe a ne.....»»
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.....»»
Scientists create new overwintering sites for monarch butterflies on a warming planet
The migration of the monarch butterfly is one of the wonders of the natural world. Each autumn, a new generation of monarch butterflies is born in the northern United States and southern Canada. Hundreds of millions of these butterflies then fly to t.....»»
NASA’s Perseverance rover shares update during tricky Mars climb
NASA’s Perseverance rover has beamed back a status update from Mars, where it's in the middle of its most challenging journey yet......»»
Study: Smaller, more specific academic journals hold more sway over conservation policy
Scientists don't just want their results to be published; they want them to be published in the most influential journal they can find. This focus on a high impact factor is driven by their concerns about promotion and tenure, but it may be overlooki.....»»
More efficient phenotypic screening method can simultaneously test multiple drugs
Some of the most widely used drugs today, including penicillin, were discovered through a process called phenotypic screening. Using this method, scientists are essentially throwing drugs at a problem—for example, when attempting to stop bacterial.....»»
How can policymakers and scientists speed up progress to achieve Sustainable Development Goals?
IIASA researchers helped to identify three focus areas at the intersection of science and policy, which could foster transformative action to accelerate the achievement of the Sustainable Development Goals (SDGs). Their priorities include exploiting.....»»
Could life exist below Mars ice? Study proposes possibilities
While actual evidence for life on Mars has never been found, a new NASA study proposes microbes could find a potential home beneath frozen water on the planet's surface......»»

Cats associate human words with images, experiment suggests
A small team of animal scientists at Azabu University, in Japan, has found via experimentation that common house cats are capable of associating human words with images without prompting or reward. In their study, published in the journal Scientific.....»»
Climate change worsened deadly Nepal floods, scientists say
Climate change, along with rapid urbanization and deforestation, turbocharged floods in Nepal that killed more than 240 people last month, scientists said on Thursday......»»
Are you tasty to mosquitoes? Study offers clues into when and why they bite
As mosquitoes and mosquito-borne illnesses like dengue fever spread across the world, researchers say that a key strategy to prevent these illnesses may be dissuading the insects from biting their victims in the first place. But while scientists have.....»»

Missed out on the northern lights? Scientists expect more solar storms to produce auroras
Expect to see more northern lights in unusual places as the sun continues to sizzle, space weather forecasters said Tuesday......»»
Each glacier has a unique organic matter composition, study reveals
Melting glaciers release more than just water. Organic matter once trapped in ice can run into streams and rivers, where it becomes food for microbes. These organisms respire the organic matter back to the atmosphere in the form of carbon dioxide, wi.....»»
Fossil pollen reveals history of Southern Hemisphere Westerlies
In Bergen, Maaike Zwier analyzed pollen in sediment cores from lakes on Kerguelen Islands and South Georgia. In this way, she can say something about the local climate going back almost 12,000 years. The study is published in the journal Quaternary S.....»»
