It is difficult for lefty snails to mate with normal snails because they have genitals on the opposite side of their headIt began when a retired scientist at the Natural History Museum in London told me that he had found a rare garden snail with a left-coiling shell. In 20 years of researching the genetics of snails at universities around the world, I had never found a “lefty” garden snail. My...
At the start of the week, Liam Porr had only heard of GPT-3. By the end, the college student had used the AI model to produce an entirely fake blog under a fake name. It was meant as a fun experiment. But then one of his posts found its way to the number-one spot on Hacker News. Few people noticed that his blog was completely AI-generated. Some even hit “Subscribe.” While many have...
Alphabet Inc.'s Google has said it will no longer provide data in response to requests from Hong Kong authorities following the enactment of a new national security law imposed by...
The white rings that wrap around two massive lakes in the U.S. West are a stark reminder of how water levels are dropping and a warning that the 40 million people who rely on the Colorado River face a much drier future.
While there are many pests affecting cotton, the reniform nematode is one the most damaging, with the ability to cause annual losses of approximately $33 million within the Mid-Southern United States. Farmers struggle to manage this pest as commercially available resistance is not widespread and a limited number of products are commercially available for use in suppressing the reniform nematode.
A key component when forecasting what the Earth's climate might look like in the future is the ability to draw on accurate temperature records of the past. By reconstructing past latitudinal temperature gradients (the difference in average temperature between the equator and the poles) researchers can predict where, for example, the jet stream, which controls storms and temperatures in the...
Some have suggested we’re now successfully treating Covid-19, or that ‘herd immunity’ has finally arrived. Neither is trueCoronavirus – latest updatesSee all our coronavirus coverageWhy has the mortality rate for coronavirus decreased in the UK?

Mystery had enthralled skywatchers since the star began to lose luminosity last October – with some suggesting it could explodeThe sudden dimming of one of the Milky Way’s brightest stars, Betelgeuse, could be due to a dust cloud spewing up from its surface, astronomers have said.The mystery has enthralled skywatchers since the star – part of the Orion constellation – began to lose...
Researchers in South Africa's Border Cave have found evidence that people have been using grass bedding to create comfortable areas for sleeping and working on at least 200 000 years ago.
A new design for light-emitting diodes achieves a dramatic increase in brightness as well as the ability to create laser light -- characteristics that could make it valuable in a range of applications. The device shows an increase in brightness of 100 to 1,000 times over conventional submicron-sized LED designs.
An international team of scientists developed a method to study fast Coronal Mass Ejections, powerful ejections of magnetized matter from the outer atmosphere of the Sun. The results can help to better understand and predict the most extreme space weather events and their potential to cause strong geomagnetic storms that directly affect the operation of engineering systems in space and on Earth.
The electrochemical conversion of nitrogen to ammonia is the most promising alternative of the traditional Haber-Bosch process to achieve nitrogen fixation under ambient conditions. In this strategy, activation of high-energy triple-bonds of nitrogen is the most significant bottleneck and is commonly considered as the rate-determining step of ammonia synthesis. Scientists based in China...
Oak Ridge National Laboratory researchers have developed artificial intelligence software for powder bed 3D printers that assesses the quality of parts in real time, without the need for expensive characterization equipment.
While many programs and initiatives have been implemented to address the prevalence of substance abuse among homeless youth in the United States, they don't always include data-driven insights about environmental and psychological factors that could contribute to an individual's likelihood of developing a substance use disorder. Now, an artificial intelligence (AI) algorithm developed by...
A new study from the University of Colorado Anschutz Medical Campus challenges a decades-old hypothesis on adaptation, a key feature in how sensory cells of the inner ear (hair cells) detect sound.
A special type of aurora, draped east-west across the night sky like a glowing pearl necklace, is helping scientists better understand the science of auroras and their powerful drivers out in space.
COVID-19 patients with cardiovascular comorbidities or risk factors are more likely to develop cardiovascular complications while hospitalized, and more likely to die from COVID-19 infection, according to a new study published August 14, 2020 in the open-access journal PLOS ONE by Jolanda Sabatino of Universita degli Studi Magna Graecia di Catanzaro, Italy, and colleagues.
Changes in climate and habitat on the breeding and non-breeding grounds of migratory birds are both playing an important part in driving their long-term population changes.
Highlighting the parallels between the global health and the climate emergency, a team of researchers from the Potsdam Institute for Climate Impact Research (PIK) has analyzed what policy makers and citizens can learn from the corona outbreak and how to apply it to the global effort of reducing CO2 emissions. Their proposal: A Climate Corona Contract that unites the younger and the older...
The goal of this study was to compare International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10)Â codes with manual electronic medical records review in capturing symptoms of fever, cough and shortness of breath (dyspnea) among patients being tested for SARS-CoV-2 infection.
