Quantum technologies are radically transforming our understanding of the universe. One emerging technology is macroscopic mechanical oscillators, devices that are vital in quartz watches, mobile phones, and lasers used in telecommunications. In the q.....»»
Apollo lunar mission samples reveal origins of lunar water and its connection to Earth"s early history
A team of international scientists has unveiled groundbreaking research on the origins of lunar water, offering insights that could reshape our understanding of the Earth-moon system and the broader solar system. Published in the journal Proceedings.....»»
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......»»
Researchers highlight role "workhorse protein" plays in keeping nervous system running smoothly
A team of researchers from the University of Massachusetts Amherst is the first to show how proteins called "chaperones" are vital in ensuring that neurons can transmit signals to one another. When this neurotransmission breaks down, devastating dise.....»»
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.....»»
Valencia floods showed why coastal cities should restore their wetlands
Valencia, a city and province in south-east Spain, became synonymous with disaster in October 2024 when floods killed at least 231 people. Extreme rainfall will happen more often as the climate warms and the cost to coastal cities like Valencia is ex.....»»
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.....»»
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......»»
Capybaras found dead from rabies on Brazilian island underline need to monitor virus
Three capybaras (Hydrochoerus hydrochaeris) died from rabies on Anchieta Island in the municipality of Ubatuba, São Paulo state, Brazil, between December 2019 and January 2020. One was found dead, and two exhibited hindlimb paralysis before dying. A.....»»
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.....»»
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.....»»
