Scientists recreate molecular timers to control nanomachine activation rates
Living organisms monitor time—and react to it—in many different ways, from detecting light and sound in microseconds to responding physiologically in pre-programmed ways, via their daily sleep cycle, monthly menstrual cycle, or to changes in the.....»»
Easy tips to save money don"t always work. Here"s why.
Amid spending season and a plethora of articles listing ways to control your budget during these holidays, a Deakin University researcher warns there are no quick and easy solutions......»»

Molecular "pinball": Superfast collisions predict supercritical fluid properties
Neither gas nor liquid, supercritical fluids exhibit a unique mashup of the properties of both and arise when fluids are pushed to very high temperatures and pressures. Their properties make them ideal for a wide variety of chemical, pharmaceutical a.....»»
Optical spring enables programmable defect mode in new mechanical crystal
Mechanical crystals, also known as phononic crystals, are materials that can control the propagation of vibrations or sound waves, just like photonic crystals control the flow of light. The introduction of defects in these crystals (i.e., intentional.....»»
Molecular gardening: New enzymes discovered for protein modification pruning
Deubiquitinases (DUBs) are enzymes used by cells to trim protein modifications made from the protein ubiquitin, and thereby regulate proteins. Malfunctioning of DUBs could lead to diseases, including cancer and neurodegenerative disorders......»»
Top 10 plant and fungal species named new to science in 2024
Scientists from the Royal Botanic Gardens, Kew and their partners reveal their pick of the top 10 plants and fungi named new to science in 2024......»»
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.....»»
Massive volcanic eruptions did not cause the extinction of dinosaurs, say climate scientists
Massive volcanic eruptions on the Indian peninsula have long been proposed as an alternative cause for the demise of the dinosaurs. This phase of active volcanism took place in a period just before Earth was struck by a meteorite, 66 million years ag.....»»
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.....»»
How feelings of disconnection and lack of control fuel conspiracy beliefs—new research
Conspiracy theories have always been a part of society, offering explanations—sometimes simple, often elaborate—for complex events......»»
Where"s my qubit? Scientists develop technique to detect atom loss
Quiet quitting isn't just for burned out employees. Atoms carrying information inside quantum computers, known as qubits, sometimes vanish silently from their posts. This problematic phenomenon, called atom loss, corrupts data and spoils calculations.....»»
Uncovering a centaur"s tracks: Scientists examine unique asteroid-comet hybrid
Although our solar system is billions of years old, we've only recently become better acquainted with one of its more dynamic and captivating inhabitants known as (2060) Chiron......»»
Scientists provide insights into photosystem II under low-light conditions
In higher plants and green algae, photosystem II (PSII) usually combines with light harvesting complex II (LHCII) to form the PSII-LHCII supercomplex. Under low-light conditions, the PSII-LHCII supercomplexes are organized laterally into higher-order.....»»
Melting sea ice in Antarctica causes ocean storms, scientists say
The record-breaking retreat of Antarctic sea ice in 2023 has led to more frequent storms over newly exposed parts of the Southern Ocean, according to a study published Wednesday......»»
How bad will it get? Political scientists have a pessimism bias, study finds
The past decade has seen historic challenges for U.S. democracy and an intense focus by scholars on events that seem to signal democratic decline. But new research released Dec. 17 finds that a bias toward pessimism among U.S. political scientists of.....»»
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.....»»
Scientists witness evolution in action when two lizard species meet for the first time
In South Florida, two Caribbean lizard species met for the first time. What followed provided some of the clearest evidence to date of evolution in action......»»
Ancient clay remedy may have potential to boost modern gut health
A team of scientists has discovered that an ancient medicinal clay known as Lemnian earth (LE) could inspire new understanding of how to support present-day gut health......»»
Climate change made Cyclone Chido stronger: Scientists
Climate change intensified Cyclone Chido as it barreled toward the Indian Ocean archipelago of Mayotte, said a preliminary study by scientists studying the link between global warming and tropical storms......»»
Building a backbone: Scientists recreate the body"s "GPS system" in the lab
Scientists at the Francis Crick Institute have generated human stem cell models which, for the first time, contain notochord—a tissue in the developing embryo that acts like a navigation system, directing cells where to build the spine and nervous.....»»
