In addition, using a NASA satellite rainfall product that incorporates data from satellites and observations, NASA estimated Marie's rainfall rates the provided more clues about intensification.
Arnhem Land Maliwawa rock art opens window to past
Ticks are among nature's most hardy survivors. They've been around for at least 100 million years and used to feast on dinosaur blood. Their bodies contain anti-freeze to help them survive cold weather and their two front legs have carbon dioxide and infrared sensors to help detect when a warm-blooded mammal is approaching. Tiny hairs on their legs increases friction and allows ticks to latch onto...

Acropora spp. coral still thrives in the holdout refuge of Coral Gardens, Belize
Six dolphins were found dead in an Alabama marsh last week in what experts call an "historic mass stranding."
Millions of Latinos at risk of job displacement by automation
Coral Gardens Reef in Belize remains a refuge for Acropora spp. coral despite widespread devastation in other areas of the western North Atlantic/Caribbean, according to a study published September 30, 2020 in the open-access journal PLOS ONE by Lisa Greer from Washington and Lee University, Virginia, U.S., and colleagues.
Solar orbiter's first science data shows the sun at its quietest
The potential acceleration of job automation spurred by COVID-19 will disproportionately affect Latinos in U.S. service sector jobs, according to a new UCLA report, which also urges state and local officials to start planning now to implement programs to support and retrain these workers.
The Arctic hasn't been this warm for 3 million years–and that foreshadows big changes for the rest of the planet
Three of the Solar Orbiter spacecraft's instruments, including Imperial's magnetometer, have released their first data.
Stellar explosion in Earth's proximity
Every year, sea ice cover in the Arctic Ocean shrinks to a low point in mid-September. This year it measures just 1.44 million square miles (3.74 million square kilometers) – the second-lowest value in the 42 years since satellites began taking measurements. The ice today covers only 50% of the area it covered 40 years ago in late summer.
Pandemic provides unique opportunity for atmospheric chemists
When the brightness of the star Betelgeuse dropped dramatically a few months ago, some observers suspected an impending supernova—a stellar explosion that could also cause damage on Earth. While Betelgeuse has returned to normal, physicists from the Technical University of Munich (TUM) have found evidence of a supernova that exploded near the Earth around 2.5 million years ago.
Problems with reproduction in birds
As the COVID-19 pandemic slowed travel and business around the world, pollution emission rates dropped in response. With fewer cars on the road and clearer skies, atmospheric chemists jumped at the opportunity to study the impact of reduced emissions outside the lab. A news story in Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society, details early findings, which...
Scientists synthesise a material capable of degrading nerve agents in water
In birds and other species alike, pairs can face considerable difficulties with reproduction. Scientists at the Max Planck Institute for Ornithology in Seewiesen have now shown in an extensive analysis of 23,000 zebra finch eggs that infertility is mainly due to males, while high embryo mortality is more a problem of the females. Inbreeding, age of the parents and conditions experienced when...
Ocean warming and acidification effects on calcareous phytoplankton communities
A team from the Institute of Molecular Science (ICMol) of the University of Valencia has succeeded in synthesizing a new porous material that enables and guides the degradation of compounds analogous to nerve agents used in chemical warfare. This material will make it possible to capture and degrade this type of compounds that until now could not be eliminated. The work has been published in...
Ceramics uncovered in 3000-year-old trading network
A new study led by researchers from the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) warns that the negative effects of rapid ocean warming on planktonic communities will be exacerbated by ocean acidification.
Biodiversity: where the world is making progress–and where it's not
The tiny island of Tavolara off the coast of Sardinia may have been a trading place in the Early Iron Age (9th to 8th centuries BCE) where the original inhabitants of Sardinia, the Nuragic people, exchanged goods with people from the central Italian mainland—members of the Villanova culture. Archaeometric analyses of 3000-year-old pottery from the archaeological site of Spalmatore di Terra on...
Researchers gain new insights on river dynamics
The future of biodiversity hangs in the balance. World leaders are gathering to review international targets and make new pledges for action to stem wildlife declines. Depending on whether you are a glass half-full or half-empty person, you're likely to have different views on their progress so far.
'Street' ERTs are more useful in predicting companies' future tax outcomes, study finds
A river's only consistent attribute is change. As the Greek philosopher Heraclitus remarked, "No man ever steps in the same river twice." Although this dynamic nature is often out of sight and mind, forgetting about it has led to many a historical catastrophe.
