New hybrid virus evades immune system The flu virus and respiratory syncytial virus (RSV) can fuse together to create a virus that can evade the human immune system. Researchers who were keen to understand co-infections — in which both viruses infect someone at the same time — deliberately infected human lung cells with both viruses. They found that the RSV and the flu virus fused together to form a palm-tree-shaped hybrid, which could infect new cells even in the presence of flu antibodies. “This kind of hybrid virus has never been described before,” says virologist Pablo R. Murcia, who worked on the research. “We are talking about viruses from two completely different families combining together with the genomes and the external proteins of both viruses. It is a new type of virus pathogen.” The Guardian | 4 min read Reference: Nature Microbiology paper

Infographic of the week

Progress towards the United Nations Sustainable Development Goals (SDGs) — a set of commitments that aim both to end poverty and protect the environment — has stalled, in part owing to a failure to adjust institutions of science and governance to meet the SDGs. Since the goals were agreed in 2015, the rate at which research from high-income countries on, or about, the SDGs is being published has mostly either plateaued or is falling. It’s a different story for low- and middle-income countries, where funding and policy systems are clearly more aligned with the goals. Two-thirds of research published in the poorest countries has some connection to the SDGs, compared with around 35% in high-income countries.

The aye-aye inserts ‘the entire length of its extra-long, skinny and highly mobile middle finger into the nasal passages’. (imageBROKER/Alamy)

Nose-picking primates eat their own snot Researchers have discovered that aye-ayes (Daubentonia madagascariensis) — round-eyed, nocturnal primates found in Madagascar — use their long, skinny middle fingers to pick their noses, and eat the mucus. Biologist Anne-Claire Fabre recalls her surprise when she first saw a captive aye-aye picking and licking, because the creature’s whole middle finger seemed to disappear up its nose. “It is nearly 8 centimetres — it is really long, and I was wondering where this finger is going,” she says. To solve the anatomical puzzle, researchers carried out CT scans to build 3D models of the aye-aye’s head and hand, revealing that the creature’s long digit could extend into its sinus, throat and mouth.

Recent work suggests that all forms of acoustic communications had a common origin 470 million years ago, evolving in concert with lungs, reports Elizabeth Pennisi for Science Magazine. All land vertebrates vocalize, but only some can mimic sounds that they hear. Neuroscientist Erich Jarvis has found that this “vocal learning” uses the same brain pathways as language. Jordana Cepelewicz interviewed Jarvis for Quanta in 2018. Stretchy Protons Stunt the Strong Force Protons are stretchier than expected. Their constituent quarks are pulled apart by an electric field more easily than the Standard Model predicts, reports James Riordon for Science News. Quantum chromodynamics (QCD), the model that describes how quarks interact with one another, is a notoriously complicated theory. In 2020 Charlie Wood wrote for Quanta about the unwieldy calculations needed for QCD. Recently, physicists helped create a series of animations to better understand the physics happening inside a proton. Last week, Quanta published an explainer using visuals from the collaboration.

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.
