Machines, thanks to novel algorithms and advances in computer technology, can now learn complex models and even generate high-quality synthetic data such as photo-realistic images or even resumes of imaginary humans. A study recently published in the international journal PLOS Genetics uses machine learning to mine existing biobanks and generate chunks of human genomes which do not belong to real humans but have the characteristics of real genomes.
SARS-CoV-2 mutations similar to those in the B1.1.7 UK variant could arise in cases of chronic infection, where treatment over an extended period can provide the virus multiple opportunities to evolve, say scientists.
Bird species that live in their natural habitats can help zoos learn how to manage those in captivity, according to a new review.
Birds are the most diverse group housed by zoos around the world, but zoo-based research tends not to focus on birds.
A new article published in the journal Birds, by Dr Paul Rose of the University of Exeter, suggests zoos can improve management of birds by looking at how species live in their natural habitats.
Neuroscientists at McMaster University have found a link between children who are at risk for developmental coordination disorder (DCD), a common condition that can cause clumsiness, and difficulties with time perception such as interpreting changes in rhythmic beats.
Accurate time perception is crucial for basic skills such as walking and processing speech and music.
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.
