    Ignoring climate change will yield ‘untold suffering,’ panel of 14,000 scientists warns

    Nearly 14,000 scientists have signed a new climate emergency paper, warning that “untold suffering” awaits the human race if we don’t start tackling global warming head-on, effective immediately. The new paper, published July 28 in the journal BioScience and led by researchers from Oregon State University, is an update of a 2019 paper that declared a global “climate emergency” and evaluated Earth’s vital signs based on 31 variables — including greenhouse gas emissions, surface temperature changes, glacial ice mass loss, Amazon rainforest loss, plus various social factors like global gross domestic product (GDP) and fossil fuel subsidies. Unsurprisingly, the authors of the new paper find that Earth‘s vitals have only…

    Thousands of scientists warn climate tipping points ‘imminent’ | Climate News

    Thousands of scientists have repeated calls for urgent action to tackle the climate emergency, warning that several tipping points are now imminent. The researchers, part of a group of more than 14,000 scientists who have signed on to an initiative declaring a worldwide climate emergency, said in an article published in the journal BioScience on Wednesday that governments had consistently failed to address “the overexploitation of the Earth”, which they described as the root cause of the crisis. Since a similar assessment in 2019, they noted an “unprecedented surge” in climate-related disasters, including flooding in South America and Southeast Asia, record-shattering heatwaves and wildfires in Australia and the US, and…

    Galileo Project: scientists to search for signs of extraterrestrial technology | Space

    A team of scientists will embark on a new international research project led by Harvard University to search for evidence of extraterrestrial life by looking for advanced technology it may leave behind. The Galileo Project is led by the Harvard astronomy professor Avi Loeb. Loeb co-founded the project with Frank Laukien, CEO of Bruker Corporation, a Massachusetts-based manufacturer of scientific equipment. “Given the recently discovered abundance of Earth-Sun systems, the Galileo Project is dedicated to the proposition that humans can no longer ignore the possible existence of Extraterrestrial Technological Civilizations (ETCs),” the team announced in a statement on Monday. The project follows the US government’s report from last month on…

    Scientists may have cracked the mystery of da Vinci’s DNA

    Leonardo da Vinci — the great Renaissance artist, inventor and anatomist — has 14 living male relatives, a new analysis of his family tree reveals. The new family tree could one day help researchers determine if bones interred in a French chapel belong to the Italian genius.  Historians Alessandro Vezzosi and Agnese Sabato have spent more than a decade tracing the genealogy of the famed “Mona Lisa” painter. Their map stretches across 690 years, 21 generations and five family branches, and will be vital in helping anthropologists sequence the DNA of da Vinci by sequencing the DNA of his descendants, the researchers say.  Related: Leonardo da Vinci’s 10 best ideas…

    Scientists Discover a New Plant Organ | Science

    The thale cress may be a humble weed, but to science, it’s an important model organism. Researchers use the plant as a proxy in experiments to represent other plants, animals and even humans—thanks to its relatively short lifecycle and simple genome. Scientists have even sent the thale cress to the International Space Station and the moon. “It’s the fruit fly of the plant world,” says Tim Gookin, a molecular biologist who formerly worked at the Pennsylvania State University. But despite the fact that scientists have scrutinized the plant, Aribidopsis thalania, since the 16th century, the thale cress still manages to surprise. Gookin and his team have found that the thale…

    50 years ago, scientists predicted steady U.S. population growth

    Information outflow – Science News, June 5, 1971 The United States’ population is growing at a rate of one percent a year, and even with lower fertility rates this trend will probably continue. If the fertility rate dropped to 2.1 children per woman, the population of the country would level off in the year 2037 at 267 million. But, this would require an unlikely 50 percent decrease in the birth rate. Update Those projections, based on 1970 census data, recently veered off course. As of April 2020, about 331.5 million people lived in the United States, according to census data. But from July  2019 to July 2020, the population grew by…

    Scientists Finally Sequence Entire Genome

    Scientists say they have finally sequenced the full human genome. This includes a big portion of the missing 8 percent from the first “draft” of the genome. Two competing startup technologies helped power the newly sequenced portions. Twenty-one years ago, researchers announced the first “draft” of sequencing the complete human genome. It was a monumental achievement, but the sequence was still missing about 8 percent of the genome. Now, scientists working together around the world say they’ve finally filled in that reclusive 8 percent. ➡ You think science is badass. So do we. Let’s nerd out over it together. If their work holds up to peer review and it turns…
