A non-target screening method for hazardous substances in the marine environment
Many anthropogenic chemicals eventually end up in the environment. Some of these can harm wildlife and can affect us humans. A major challenge is to identify these substances before they cause too much damage to the ecosystem and public health......»»
A look into cloudy liquids: New method makes the expansion of turbid drops in water visible
When driving though a bank of fog, car headlights are only of limited help as the light is scattered by the water particles suspended in the air. The situation is similar when you try to observe the inside of a drop of milk in water or the internal s.....»»
Catching prey with grappling hooks and cannons: The unusual weapons arsenal of a predatory marine bacterium
Countless bacteria call the vastness of the oceans home, and they all face the same problem: the nutrients they need to grow and multiply are scarce and unevenly distributed in the waters around them. In some spots they are present in abundance, but.....»»
More efficient phenotypic screening method can simultaneously test multiple drugs
Some of the most widely used drugs today, including penicillin, were discovered through a process called phenotypic screening. Using this method, scientists are essentially throwing drugs at a problem—for example, when attempting to stop bacterial.....»»
Environmental DNA and epidemics in wood frogs: Collaboration examines eDNA"s precision in population size estimation
Tracy Rittenhouse, associate professor of natural resources and the environment in UConn's College of Agriculture, Health and Natural Resources (CAHNR), was doing an experiment to study ranavirus epidemics in wood frogs. When Meghan Parsley, then a P.....»»
Plant fungus provides new drug target for colorectal cancer therapy
Novel chemical compounds from a fungus could provide new perspectives for treating colorectal cancer, one of the most common and deadliest cancers worldwide......»»
Forever chemicals found in bottled and tap water from around the world
Researchers found 10 'target' PFAS (perfluoroalkyl substances)—chemicals which do not break down in nature—in tap and bottled water available for consumption in major cities in the UK and China. Perfluorooctanoic acid (PFOA) and perfluorooctane s.....»»
New method for measuring luminescence lifetime offers versatility in scientific imaging
Oxygen is a key molecule for life, and in order to understand ecosystem dynamics it can be important to follow its ways in much detail. Optical sensors that use luminescent dyes have long been used to map oxygen levels in marine systems. Oxygen reduc.....»»
Longer wildfire seasons means more bad air days
Each year in Utah and most other western states in America, the period from July through October is considered wildfire season because it typically represents the peak times atmospherically for such hazardous phenomenon. Besides the danger to propert.....»»
New method to generate photon pairs efficiently on a chip
Thin-film lithium niobate is an emerging nonlinear integrated photonics platform ideally suited for quantum applications. Through spontaneous parametric down-conversion (SPDC), it can generate correlated photon pairs for quantum key distribution, tel.....»»
Biochar nanocomposite enhances detection of acetaminophen and uric acid in urine
In recent years, the excessive use of acetaminophen (APAP) has become a significant human hazard and social burden. Rapid and automated electrochemical detection has emerged as a crucial method for measuring APAP concentration in human urine......»»
Global temperature analysis reveals deep ocean marine heat waves are underreported
While marine heat waves (MHWs) have been studied at the sea surface for more than a decade, new research published today in Nature has found 80% of MHWs below 100 meters are independent of surface events, highlighting a previously overlooked aspect o.....»»
Trace gas measurements could advance carbon cycle predictions
A novel method for estimating the rate of photosynthesis from land plants reveals that satellite observations—the current gold standard for quantifying terrestrial carbon uptake—underestimate this important metric, a result that could inform and.....»»
Researchers call for PFAS ban after alarming findings in marine environments
Washing your pots and pans—among many other day-to-day activities—could have a significant impact on marine environments for hundreds of years, according to a new study......»»
North Korean hackers use newly discovered Linux malware to raid ATMs
Once, FASTCash ran only on Unix. Then came Windows. Now it can target Linux, too. In the beginning, North Korean hackers compromised the banking infrastructure running AIX, IBM’.....»»
Ship-mounted camera systems help increase protections for marine mammals
Vessel strikes and entanglement are some of the leading causes of injury and death to marine animals such as whales. Increasingly urbanized waterways, warming oceans, changes in prey distribution—and in some cases, increasing species populations—.....»»
Scientists discover chemical probes for previously "undruggable" cancer target
Hormone-driven cancers, like those of the breast and prostate, often rely on a tricky-to-target protein called Forkhead box protein 1 (FOXA1). FOXA1 mutations can enable these types of cancers to grow and proliferate. Today, FOXA1 is notoriously diff.....»»
Scientists apply ancient construction methods to help fabricate modern microparticles
Inspired by the ancient East Asian method of constructing wooden structures using a "tongue and groove" technique, Nanyang Technological University, Singapore (NTU Singapore) scientists have developed a new approach to fabricating advanced ceramic mi.....»»
El Niño Southern Oscillation caused spike in 2023 temperatures, study finds
A study by scientists at the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science identified El Niño–Southern Oscillation as the primary cause of the spike in global surface temperature in 2023, not human-induced climate.....»»
New bacteria-based therapy shows promise for fighting cancer
Even as cancer remains a leading cause of death globally, bacteria-based cancer therapy presents an exciting and innovative treatment option. Owing to their ability to penetrate the rigid stromal barrier, bacteria can naturally target solid tumors an.....»»
Can biodiversity credits unlock billions for nature?
For supporters, biodiversity credits could unlock billions in much-needed funding for nature, but critics fear a repeat of scandals that have dogged other financial approaches to protecting the environment......»»
