Biologists discover that rising temperature accelerates aging in mosquitoes, weakening their immune systems
A study published January 10, 2024 in PLOS Pathogens found that mosquitoes age more quickly when temperatures are higher. This aging, in turn, weakens the mosquito immune system and makes them more likely to get infected with disease. Because global.....»»
Grapevine protein resembles animal ion transport function, researchers discover
Researchers at the University of Adelaide have discovered that a protein which mediates the transport of alkali metal ions, such as potassium, and halide ions across plant membranes acts similarly to a protein found in animals......»»
Warming exacerbates oxygen depletion in the Baltic Sea, undermining nutrient reduction efforts
Eutrophication and rising water temperatures are taking an increasing toll on the Baltic Sea, leading to dangerous oxygen depletion in deeper water layers and threatening many marine organisms. Despite successful efforts to reduce nutrient inputs, ri.....»»
Genetically encoded biosensors measure living cells" charge in real time
Biological cells have many vital functions in the organism. For example, they produce proteins, carbohydrates and fats. But they are also responsible for detoxifying harmful molecules and transmitting signals and immune defense steps. A so-called red.....»»
Simulations of hominin Lucy help show how long distance running evolved in modern humans
A team of natural scientists, musculoskeletal specialists, and evolutionary biologists affiliated with several institutions in the U.K., working with a colleague from the Netherlands, has found via simulations, that the famous early hominin Lucy, cou.....»»
Active particles reorganize 3D gels into denser porous structures, study shows
Colloidal gels are complex systems made up of microscopic particles dispersed in a liquid, ultimately producing a semi-solid network. These materials have unique and advantageous properties that can be tuned using external forces, which have been the.....»»
Study reveals flies more vulnerable than bees to climate change
Despite their reputation as buzzing nuisances, flies serve a critical role as some of the Earth's most prolific pollinators—and new research led by Penn State scientists suggests they are increasingly at risk due to rising global temperatures......»»
Discovery of egg"s immune-like attack on sperm mitochondria may aid fertility
Within minutes of fertilization, the egg of a fruit fly becomes a scene from the battle of the sexes. The egg attacks and destroys the cellular "power plants" (mitochondria) from the sperm that had fertilized it, so that only its own mitochondria rem.....»»
Molecular tool demonstrates how bad eggs are identified for destruction by reproductive system
The biological factory that produces reproductive cells has a robust quality control system to identify and eliminate eggs with chromosomal abnormalities. For years, cell biologists have sought to uncover the mechanisms behind this system, relying on.....»»
Scientists document rich biodiversity along underexplored Chilean coastline
An international team of scientists on board a recent Schmidt Ocean Institute R/V Falkor (too) expedition surveyed nearly 20 methane seeps, some of which are new discoveries, and four submarine canyon systems previously never before seen by humans......»»
Ancient Mars" thick crust could have supported hidden water reservoirs and rare magmas, new research suggests
A new study explores how variations in Mars' crustal thickness during its ancient history may have influenced the planet's magmatic evolution and hydrological systems. The research, published in Earth and Planetary Science Letters, suggests that the.....»»
Cellular RNA plays key role in antiviral defense, study finds
Scientists have uncovered a new role for a cell's own RNA in fending off attacks by RNA viruses. Some of the cell's RNA molecules, researchers found, help regulate antiviral signaling. These signals are part of the intricate coordination of immune re.....»»
Faster way to calculate electron structure makes it easier to discover new materials
Figuring out certain aspects of a material's electron structure can take a lot out of a computer—up to a million CPU hours, in fact. A team of Yale researchers, though, are using a type of artificial intelligence to make these calculations much fas.....»»
New software unlocks secrets of cell signaling, showing realistic simulations
Researchers at University of California San Diego have developed and tested a new software package, called Spatial Modeling Algorithms for Reactions and Transport (SMART), that can realistically simulate cell-signaling networks—the complex systems.....»»
Miniaturized all-fiber photoacoustic spectrometer for intravascular gas detection rivals lab-based systems
Miniaturized spectroscopy systems that can detect trace concentrations at the parts-per-billion (ppb) level are of the utmost importance in applications ranging from environmental monitoring and industrial process control to biomedical diagnostics. H.....»»
Clouds obscure link between extreme rainfall and rising temperatures
Extreme rainfall is usually defined as the heaviest 5% of rain events in a specific area. As global air temperatures rise, scientists expect extreme rainfall to increase. This is because warmer air can hold more moisture. Recent examples of more extr.....»»
Aerosols could be weakening summertime circulation in the Northern Hemisphere
Over the past several decades, summer jet streams (or west to east wind flow) and weather systems in the Northern Hemisphere have weakened. Projections suggest the trend will continue, which could make extreme heat events more likely and affect air q.....»»
Baby humpback whale recordings reveal vocalizations directed to their mothers
A team of marine biologists, zoologists, and cetologists from Université Paris-Saclay, Université d'Antananarivo and Ambodiforaha Sainte Marie has learned more about the ways baby humpback whales and their mothers communicate......»»
Ice is melting, seas are rising—how scientists are tracking the changes
Will the sea rise by 20 cm or 3 meters by 2100? This is obviously an interesting question to answer. Predicting the sea level in 75 years requires precise calculations and correct models of the melting of the ice from, e.g., Greenland. To do so, rese.....»»
Stairwell Core boosts threat intelligence for security teams
Stairwell announces Stairwell Core, which enables organizations to privately collect, store, and continuously reassess executable files so they can confidently determine if malware has affected their systems. Core offers customers an accessible entry.....»»
