Watch the video Around the Web Bees Have a Number Line In a new study, honeybees continue to display their mathematical aptitude: They order numbers from left to right, suggesting that they have a “mental number line,” Darren Incorvaia reports for Science News. In past studies, honeybees have demonstrated that they understand the concept of zero and basic arithmetic. In 2020 Susan D’Agostino interviewed biologist Scarlett Howard for Quanta about how she teaches math to bees. Do Zelda Next! Scientists taught mouse and human brain cells in a dish to play the classic video game, Pong, reports Jon Hamilton for NPR. Studying the similarities between brains and computers has inspired new, efficient computing hardware. In February Allison Whitten wrote for Quanta about an AI that runs on a brain-inspired neuromorphic chip.

Multidimensional Poverty Index 2022 Released The 2022 Multidimensional Poverty Index Report "Unpacking deprivation bundles to reduce  multidimensional poverty" finds that reducing poverty at scale is possible and unveils new 'poverty profiles' that can offer a breakthrough in development efforts to tackle the interlinked aspects of poverty. The report identifies a series of 'deprivation bundles' -- recurring patterns of poverty -- that commonly impact those who live in multidimensional poverty across the world. The data are used to identify the poverty profiles that are more common in certain places. This is a crucial step in designing strategies that address multiple aspects of poverty at the same time. FULL REPORT #CFM #IHME Publication date:  October 14, 2022 KEY TAKEAWAYS: We designed the Burden of Proof study to help consumers makes sense of confusing health guidance by assigning a star-rating to pairs of risks and outcomes. We reviewed thousands of studies on risks like smoking and eating red meat to determine how strong the evidence was that those risks lead to health impacts, and whether it’s worth changing your behavior. Five-star ratings – like smoking & lung cancer and high blood pressure & heart attacks – indicate that there is strong evidence of association. One-star ratings indicate that there may be no association at all, or that more evidence is needed on the topic. #NYT Science Gamma-ray burst may represent the most powerful cosmic explosion ever recorded (NASA/Swift/A. Beardmore (University of Leicester)) Astronomers have spotted a bright blast of high-energy light that may be the most powerful  cosmic explosion ever detected. The high-energy emission known as a gamma-ray burst (GRB) – the most powerful type of  explosion seen in our universe since the Big Bang – likely represents the moment a dying star collapsed into a black hole, triggering a tremendous supernova explosion, astronomers  said.  Full Story: Live Science (10/19) Energy jet traveling 7 times the speed of light appears to break the laws of physics (NASA Goddard) Astronomers have detected a gargantuan blast of energy from space that appears to be doing the impossible: Traveling seven times faster than the speed of light.  This is, of course, an optical illusion — a rare and mind-boggling phenomenon called superluminal motion, which occurs when particles come very close to moving at the speed of light. In this case, scientists detected a jet of energy blasting out of a stellar collision site at a staggering 99.97% of the speed of light — about 670 million mph (1.07 billion km/h), according to a study published Oct. 12 in the journal Nature.   Full Story: Live Science (10/19)  #UN International Day for the Eradication of Poverty 17 October #CHC da Santa Casa #Academia Nacional de Medicina É com muita honra que abordarei nesta quinta-feira, 20/10, às 18:40, na Academia Nacional de Medicina, a relação da Semana da Arte Moderna com a ciência médica.

The risk of death from influenza has declined over time, but globally, hundreds of thousands of people still die from the disease each year. by Saloni Dattani and Fiona Spooner October 20, 2022 Globally, hundreds of thousands of people die from seasonal influenza every year. During large flu pandemics, when influenza strains evolved substantially, the death toll was even higher. But the risk of dying from influenza has declined substantially over time from improvements in sanitation, healthcare, and vaccination.  People born in 1940 had around a third of the risk of dying from influenza as those born in 1900 – even when they reached the same age. This decline continued, and those born in 1980 have a risk of half that of those born in 1940. #Obituário (ZH) (*1925+16/10/2022 em Brasília) O sentimento de pesar encontra alguma compensação na memória de muitos encontros e projetos em que trabalhamos junto. #Nature NEWS 18 October 2022 First known map of night sky found in Medieval parchment Fabled star catalogue by ancient Greek astronomer Hipparchus had been feared lost.

Hidden beneath Christian texts, scholars have discovered what seems to be part of the long-lost star catalogue of the astronomer Hipparchus — believed to be the earliest known attempt to map the entire sky.

Credit: ESA/Gaia/DPAC (CC BY-SA 3.0 IGO) The best available map of the Milky Way just got better. The latest update from the Gaia space observatory — which is tracking more than 1 billion stars in the Galaxy — provides not just a static image, but a  moving picture of how stars will shift over time. The data will underpin studies that range from the origins and evolution of the Galaxy to locating its dark matter./.../
