Scientists at the Francis Crick Institute have found important structural similarities between SARS-CoV-2 and a pangolin coronavirus, suggesting that a pangolin coronavirus could infect humans.
While SARS-CoV-2 is thought to have evolved from a bat coronavirus, its exact evolutionary path is still a mystery. Uncovering its history is challenging as there are likely many undiscovered bat coronaviruses and, due to differences between bat coronaviruses and SARS-CoV-2, it is thought that the virus may have passed to humans via at least one other species.
A banking crisis is often seen as a self-fulfilling prophecy: The expectation of bank failure makes it happen. Picture people lining up to withdraw their money during the Great Depression or customers making a run on Britain's Northern Rock bank in 2007.
Plastics made from crops such as maize or sugarcane instead of fossil fuels are generally considered sustainable. One reason is that plants bind CO2, which compensates for the carbon released into the atmosphere when plastics are disposed. However, there is a catch: With increasing demand for raw materials for bioplastic production, the areas under cultivation may not be sufficient. As a result, natural vegetation is often converted to agricultural land and forests are cut down. This in turn releases large amounts of CO2.
The open ocean is a harsh place for newborn fishes. From the minute larvae hatch from their eggs, their survival depends upon finding food and navigating ocean currents to their adult habitats--all while avoiding predators. This harrowing journey from egg to home has long been a mystery, until now.
Treatment for HIV has improved tremendously over the past 30 years; once a death sentence, the disease is now a manageable lifelong condition in many parts of the world. Life expectancy is about the same as that of individuals without HIV, though patients must adhere to a strict regimen of daily antiretroviral therapy, or the virus will come out of hiding and reactivate. Antiretroviral therapy prevents existing virus from replicating, but it can't eliminate the infection. Many ongoing clinical trials are investigating possible ways to clear HIV infection.
To survive the open ocean, tiny fish larvae, freshly hatched from eggs, must find food, avoid predators, and navigate ocean currents to their adult habitats. But what the larvae of most marine species experience during these great ocean odysseys has long been a mystery, until now.
The Institute for Scientific Information on Coffee (ISIC) published a new report today, titled 'Coffee and sleep in everyday lives', authored by Professor Renata Riha, from the Department of Sleep Medicine at the University of Edinburgh.
Remember the first rule of fight club? That's right: You don't talk about fight club. Luckily, the rules of Hollywood don't apply to science. In new published research, University of Arizona researchers report what they learned when they started their own "fight club" - an exclusive version where only insects qualify as members, with a mission to shed light on the evolution of weapons in the animal kingdom.
TOKYO --Toshiba Corporation (TOKYO: 6502) and Toshiba Digital Solutions Corporation (collectively Toshiba), industry leaders in solutions for large-scale optimization problems, today announced the Ballistic Simulated Bifurcation Algorithm (bSB) and the Discrete Simulated Bifurcation Algorithm (dSB), new algorithms that far surpass the performance of Toshiba's previous Simulated Bifurcation Algorithm (SB). The new algorithms will be applied to finding solutions to highly complex problems in areas as diverse as portfolio management, drug development and logistics management.
Catalysts are key materials in modern society, enabling selective conversion of raw materials into valuable products while reducing waste and saving energy. In case of industrially relevant oxidative dehydrogenation reactions, most known catalyst systems are based on transition metals such as Iron, Vanadium, Molybdenum or Silver.
UCC palaeontologists have discovered new evidence that the fate of vertebrate animals over the last 400 million years has been shaped by microscopic melanin pigments.
The FinnBrain research of the University of Turku has demonstrated for the first time that the stress the father has experienced in his childhood is connected to the development of the white matter tracts in the child's brain. Whether this connection is transmitted through epigenetic inheritance needs further research.
A healthy person has a general balance of good and bad bacteria. But that balance is thrown off when someone gets sick. So, to help boost their levels of good bacteria, many people take probiotic supplements -- live bacteria inside of a pill. Various commercial probiotic supplements are available for consumer purchase, and while health experts generally agree about their overall safety, controversy surrounds their efficacy.
New research carried out by City data scientist, Dr Andrea Baronchelli, and colleagues, into the dark web marketplace (DWM) trade in products related to COVID-19, has revealed the need for the continuous monitoring of dark web marketplaces (DWMs), especially in light of the current shortage and availability of coronavirus vaccines.
ADELPHI, Md. -- A new quantum sensor can analyze the full spectrum of radio frequency and real-world signals, unleashing new potentials for soldier communications, spectrum awareness and electronic warfare.
Army researchers built the quantum sensor, which can sample the radio-frequency spectrum--from zero frequency up to 20 GHz--and detect AM and FM radio, Bluetooth, Wi-Fi and other communication signals.
