A new study shows that if the population were fixed at current levels, the risk of population displacement due to river floods would rise by ~50% for each degree of global warming. However, if population increases are taken into account, the relative global flood displacement risk is significantly higher.
The Event Horizon Telescope (EHT) collaboration, who produced the first ever image of a black hole, has revealed today a new view of the massive object at the centre of the M87 galaxy: how it looks in polarised light. This is the first time astronomers have been able to measure polarisation, a signature of magnetic fields, this close to the edge of a black hole. The observations are key to explaining how the M87 galaxy, located 55 million light-years away, is able to launch energetic jets from its core.

A new study suggests that Sargramostim, a medication often used to boost white blood cells after cancer treatments, is also effective in treating and improving memory in people with mild-to-moderate Alzheimer's disease. This medication comprises of a natural human protein produced by recombinant DNA technology (yeast-derived rhu GM-CSF/Leukine®).
The talented athletes are there. The cheering fans are there. But the media? It's nowhere to be found.
This is the reality of women's sports, which continue to be almost entirely excluded from television news and sports highlights shows, according to a USC/Purdue University study published on March 24th in Communication & Sport.
(Boston)--Being persistently lonely during midlife (ages 45-64) appears to make people more likely to develop dementia and Alzheimer's Disease (AD) later in life. However, people who recover from loneliness, appear to be less likely to suffer from dementia, compared to people who have never felt lonely.
Researchers from University of Minnesota, New York University, University of Pennsylvania, BI Norwegian Business School, University of Michigan, National Bureau of Economic Research, and University of North Carolina published a new paper in the Journal of Marketing that examines how advances in machine learning (ML) and blockchain can address inherent frictions in omnichannel marketing and raises many questions for practice and research.
Given the finite nature of fossil fuel reserves and the devastating environmental impacts of relying on fossil fuels, the development of clean energy sources is among the most pressing challenges facing modern industrial civilization. Solar energy is an attractive clean energy option, but the widescale implementation of solar energy technologies will depend on the development of efficient ways of converting light energy into chemical energy.
A research group at the RIKEN Center for Computational Science (R-CCS) has found that glycans--sugar molecules--play an important role in the structural changes that take place when the virus which causes COVID-19 invades human cells. Their discovery, which was based on supercomputer-based simulations, could contribute to the molecular design of drugs for the prevention and treatment of COVID-19. The research was published in the Biophysical Journal.
Tokyo, Japan - Scientists from the Graduate School of Information Science and Technology at The University of Tokyo calculated the efficiency of the sensory network that bacteria use to move towards food and found it to be optimal from an information theory standpoint. This work may lead to a better understanding of bacterial behavior and their sensory networks.
Imbued with special electric, mechanical and other physical properties due to their tiny size, nanofibers are considered leading-edge technology in biomedical engineering, clean energy and water quality control, among others. Now, researchers in Italy and UK have developed an automatic process to assess nanofiber fabrication quality, producing 30% more accurate results than currently used techniques.
Details were published on January 2021 in IEEE/CAA Journal of Automatica Sinica, a joint publication of the IEEE and the Chinese Association of Automation.
In a ground-breaking first, researchers have fabricated 3D scaffold implants containing antibiotics at high temperatures. These scaffolds not only support bone regeneration but manage the bone infections that can arise as a result of injury or surgery.
A genetic variation that regulates iron metabolism may enhance athletes' endurance performance, researchers at the University of Toronto have shown.
The findings could help explain studies that show an association between the genetic variation and elite athletes across many sports, and may help competitive athletes fine-tune their iron intake to boost performance.
The variation, found in the homeostatic iron regulator (HFE) gene, is a known cause of iron overload, a condition called hemochromatosis in which the body absorbs too much iron leading to organ and joint damage.
Usually scaled, the skin of fish can also be naked or made up of bony plates that form an armour, sometimes even covered with teeth. But how has this skin evolved over the ages? To answer this question, researchers at the University of Geneva (UNIGE), Switzerland, have reconstructed the evolution of the protective skin structures in fish, going back to the common ancestor of ray-finned fish, more than 420 million years ago.
The tiger shark is one of the largest predatory sharks known today. This shark is a cosmopolitan species occurring in all oceans worldwide. It is characterized by a striped pattern on its back, which is well marked in juveniles but usually fades in adults.
