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.....»»
A method to switch between optical pulling and pushing forces by altering the shape of Fermi arcs in Weyl systems
Optical forces, which act like an invisible "hand," are capable of precisely controlling tiny particles. Optical tweezers, a well-known tool, use this force to capture and manipulate small objects such as cells, bacteria, and viruses. This effect is.....»»

Visible light energy yields two-for-one deal when added to carbon dioxide recycling process
By combining visible light and electrochemistry, researchers have enhanced the conversion of carbon dioxide into valuable products and stumbled upon a surprising discovery. The team found that visible light significantly improved an important chemica.....»»
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.....»»
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.....»»
Could life exist below Mars ice? Study proposes possibilities
While actual evidence for life on Mars has never been found, a new NASA study proposes microbes could find a potential home beneath frozen water on the planet's surface......»»
More Apple Pay installment options, and PayPal balance will be visible in Apple Wallet
More Apple Pay installment options are available from today, and additional buy now pay later providers are promised. Apple Pay users in both the US and UK now have the choice of installment loans from two different providers, with more on the way.....»»
Six new Copernicus missions to provide detailed environmental data
The Copernicus Sentinel Expansion Missions are a major leap forward in Europe's Earth observation capabilities. With the United Kingdom's re-entry to the EU's Copernicus program, funding has been confirmed to complete the development of all six Coper.....»»
How the invasive spiny water flea spread across Canada, and what we can do about it
Across the tranquil waters of Canada's vast network of lakes and rivers, a quiet invader is on the move. The spiny water flea, Bythotrephes cederströmii, is a microscopic predator that is forever altering the ecological fabric of aquatic habitats in.....»»
Water crisis threatening world food production: report
Inaction on the water crisis could put more than half of the world's food production at risk by 2050, experts warned in a major report published Thursday......»»
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.....»»
Mechanism of cobalt–manganese catalysts deciphered
Conventional catalysts for hydrogen production via water electrolysis usually contain precious metals and are expensive. However, cheaper alternatives have been developed, for example cobalt–manganese catalysts. They have a high activity and are st.....»»
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......»»

Could ‘Early Dark Energy’ Resolve the Mystery of Cosmic Expansion?
Estimates of how fast the universe is expanding disagree. Could a new form of dark energy resolve the problem?.....»»
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.....»»
Solar storms are like buses: You wait 20 years for one, and then two come at once
This week across much of the world, including the UK, the majestic aurora borealis (Northern Lights) was once again visible to us......»»
Each glacier has a unique organic matter composition, study reveals
Melting glaciers release more than just water. Organic matter once trapped in ice can run into streams and rivers, where it becomes food for microbes. These organisms respire the organic matter back to the atmosphere in the form of carbon dioxide, wi.....»»
