Published Deep neural network provides robust detection of disease biomarkers in real time
(via sciencedaily.com) Original source A lab has developed a deep neural network that improves the accuracy of their unique devices for detecting pathogen biomarkers.
Published Scientists present evidence for a billion-years arms race between viruses and their hosts
(via sciencedaily.com) Original source Researchers have proposed a new evolutionary model for the origin of a kingdom of viruses called Bamfordvirae, suggesting a billion-years evolutionary arms race between two groups within this kingdom and their hosts.
Published A stormy, active sun may have kickstarted life on Earth
(via sciencedaily.com) Original source The first building blocks of life on Earth may have formed thanks to eruptions from our Sun, a new study finds. A series of chemical experiments show how solar particles, colliding with gases in Earth's early atmosphere, can form amino acids and carboxylic acids, the basic building blocks of proteins and organic life.
Published Fossil find in California shakes up the natural history of cycad plants
(via sciencedaily.com) Original source According to researchers, a new analysis of an 80-million-year-old permineralized pollen cone found in the Campanian Holz Shale formation located in Silverado Canyon, California, offers a more accurate cycad natural history -- one where the plants diversified during the Cretaceous.
Published Researchers model 'link' between improved photosynthesis and increased yield
(via sciencedaily.com) Original source A team has modeled improving photosynthesis through enzyme modification and simulated soybean growth with realistic climate conditions, determining to what extent the improvements in photosynthesis could result in increased yields.
Published Wiggly proteins guard the genome
(via sciencedaily.com) Original source Dynamic network in the pores of the nuclear envelope blocks dangerous invaders.
Published Toys demonstrate how biological machines move
(via sciencedaily.com) Original source By connecting small self-propelling toys in a chain, researchers have found the key to studying the movement of microscopic organisms and molecular motors inside our cells.
Published Do people and monkeys see colors the same way?
(via sciencedaily.com) Original source New findings in color vision research imply that humans can perceive a greater range of blue tones than monkeys do. Distinct connections found in the human retina may indicate recent evolutionary adaptations for sending enhanced color vision signals from the eye to the brain.
Published New mechanisms regulating plant response to temperature
(via sciencedaily.com) Original source Discovery of a new protein complex helps scientists understand how plants interpret changes in temperature over time
Published Webb finds water vapor, but from a rocky planet or its star?
(via sciencedaily.com) Original source Astronomers used NASA's James Webb Space Telescope to study a rocky exoplanet known as GJ 486 b. It is too close to its star to be within the habitable zone, with a surface temperature of about 800 degrees Fahrenheit (430 degrees Celsius). And yet, their observations show hints of water vapor.
Published Herpes study adds to understanding of viral reinfections, how to potentially prevent them
(via sciencedaily.com) Original source A new study on herpes infections of the eye helps shed light on the question of viral reinfections by identifying a key protein involved in viral reinfections that could be targeted by antiviral drugs.
Published Machine learning helps scientists identify the environmental preferences of microbes
(via sciencedaily.com) Original source A machine-learning approach can give scientists insight into the environmental preferences of microbes, based only on their genes. The approach has practical research implications: it could help researchers more efficiently grow bacteria in the laboratory. It could also lead to smarter use of microbes in agriculture, ecological restoration, and even probiotics.
Published Previously unknown intercellular electricity may power biology
(via sciencedaily.com) Original source Researchers have discovered that the electrical fields and activity that exist through a cell's membrane also exist within and around another type of cellular structure called biological condensates. Like oil droplets floating in water, these structures exist because of differences in density. Their foundational discovery could change the way researchers think about biological chemistry. It could also provide a clue as to how the first life on Earth harnessed the energy needed to arise.
Published New research redefines mammalian tree of life
(via sciencedaily.com) Original source Scientists from around the globe are using the largest mammalian genomic dataset in history to determine the evolutionary history of the human genome in the context of mammalian evolutionary history. Their ultimate goal is to better identify the genetic basis for traits and diseases in people and other species.
Published Artificial photosynthesis for environmentally friendly food production
(via sciencedaily.com) Original source Ensuring the supply of food to the constantly growing world population and protecting the environment at the same time are often conflicting objectives. Now researchers have successfully developed a method for the synthetic manufacture of a nutritional protein using a type of artificial photosynthesis. The animal feed industry is the primary driver of high demand for large volumes of this nutritional protein L-alanine, which is also suitable for use in meat substitute products.
Published Astronomers detect 'nearby' black hole devouring a star
(via sciencedaily.com) Original source Astronomers have discovered a new 'tidal disruption event,' in which the center of a galaxy lights up as its supermassive black hole rips apart a passing star. The outburst is the closest tidal disruption event observed to date, and one of the first to be identified at infrared wavelengths.
Published Scientists identify antivirals that could combat emerging infectious diseases
(via sciencedaily.com) Original source A new study has identified potential broad-spectrum antiviral agents that can target multiple families of RNA viruses that continue to pose a significant threat for future pandemics.
Published Superflare with massive, high-velocity prominence eruption
(via sciencedaily.com) Original source A team of Japanese astronomers used simultaneous ground-based and space-based observations to capture a more complete picture of a superflare on a star. The observed flare started with a very massive, high-velocity prominence eruption. These results give us a better idea of how superflares and stellar prominence eruptions occur.
Published Plastic particles themselves, not just chemical additives, can alter sex hormones
(via sciencedaily.com) Original source A new study used a pioneering technique to deliver endocrine-disrupting aerosolized micro-nano-plastics to female lab rats.
Published The reasons why insect numbers are decreasing
(via sciencedaily.com) Original source Researchers are investigating the causes and consequences of the worldwide insect decline as well as considering potential countermeasures.
