Scientists counted 49 ways Australia is destroying the ecosystems we hold dear—but there is hope
Australia's ecosystems face an unprecedented crisis. From rainforests in the continent's north to the alpine bogs and fens of the alps, ecosystems are being pushed towards collapse......»»
Researchers call for harnessing agrifood value chains to help farmers be climate-smart
The global food system is uniquely vulnerable to climate impacts, making adaptation of paramount importance. While contributing roughly one-third of total anthropogenic emissions, food systems around the world fortunately also hold immense potential.....»»
"Unprecedented" climate extremes are everywhere—baselines for what"s normal will need to change
Extreme temperature and rainfall events are increasing around the world, including Australia. What makes them extreme is their rarity and severity compared to the typical climate......»»

Census data analysis shows the South had a much higher mortality rate than the North in the US Civil War
A small team of social scientists at New York University-Abu Dhabi has conducted what they describe as a more accurate assessment of the number of soldiers killed in the U.S. Civil War. In their study published in the Proceedings of the National Acad.....»»
Chemists find alkyl groups are electron-withdrawing, challenging a century-old belief
Scientists are calling for changes to chemistry textbooks after discovering a fundamental aspect of structural organic chemistry has been incorrectly described for almost 100 years......»»
A fossil first: Scientists find 1.5-million-year-old footprints of two different species of human ancestors at same spot
More than a million years ago, on a hot savanna teeming with wildlife near the shore of what would someday become Lake Turkana in Kenya, two completely different species of hominins may have passed each other as they scavenged for food......»»
Coral adaptation unlikely to keep pace with global warming, warn scientists
Coral adaptation to ocean warming and marine heat waves will likely be overwhelmed without rapid reductions of global greenhouse gas emissions, according to an international team of scientists......»»
Scientists reveal structural link for initiation of protein synthesis in bacteria
Within a cell, DNA carries the genetic code for building proteins. To build proteins, the cell makes a copy of DNA, called mRNA. Then, another molecule called a ribosome reads the mRNA, translating it into protein. But this step has been a visual mys.....»»
Researchers find a possible solution to the cosmic ray muon puzzle
Scientists have a problem with cosmic rays—they produce too many muons at the Earth's surface. Cascades of muons are byproducts of high-energy cosmic rays as they collide with nuclei in the upper atmosphere, and scientists see more muons at Earth's.....»»
This Thanksgiving, I’m thankful for Persona 5
This Thanksgiving, we reflect on the small, unexpected ways that video games can make a big impact on someone's life......»»
Scientists reveal possible role of iron sulfides in creating life in terrestrial hot springs
An international team of scientists has published a study highlighting the potential role of iron sulfides in the formation of life in early Earth's terrestrial hot springs. According to the researchers, the sulfides may have catalyzed the reduction.....»»
Peru scientists unveil crocodile fossil up to 12 million years old
Paleontologists unveiled on Wednesday the fossil of a young marine crocodile dating back 10 to 12 million years that was discovered in a Peruvian desert......»»

A recent discovery made by scientists working with a sample of rock from outer space highlights one of the huge challenges that such work involves......»»
What fossilized dino feces can tell us about their rise to dominance
Scientists studied trace fossils called bromalites to reconstruct critical food webs in late Triassic, early Jurassic. Paleontologists have long puzzled over how the dinosaurs—o.....»»
Scientists discover shared genetic foundations between musical rhythm and human language
In a study published Nov. 21 in the journal Nature Human Behaviour, researchers have uncovered significant genetic connections between human language abilities and musical rhythm skills, providing new insights into the biological underpinnings of the.....»»
Scientists synthesize unsymmetrical ureas using non-phosgene method
Unsymmetrical ureas can form multiple stable hydrogen bonds with proteins. Since drugs containing urea functional groups display unique biological activities when interacting with their targets, they play an important role in drug development and med.....»»
Scientists use acoustic data to track blue and fin whale occurrences in the Arctic
The long-term analysis of blue whale and fin whale vocalizations in the eastern Fram Strait offers valuable insights into seasonal and annual patterns regarding these species' occurrence in the region. For example, blue whales can primarily be heard.....»»
Shells, teeth and bones of "weird and wonderful organisms" provide historical environmental clues
An international study shows how chemical fingerprints left by "underappreciated" aquatic organisms could help scientists monitor global environmental change......»»
Marine heat waves" hidden depths revealed in study
As the ocean warms under climate change, a better understanding of how damaging marine heat waves develop and last may help scientists predict them more accurately and forecast their impacts on marine ecosystems......»»
