Invasive species sound off about impending ecosystem changes

21/04/2024
Anticipating changes to ecosystems is often at best an educated guess, but what if there was a way to better tune into possible changes occurring? Researchers have discovered that the silent growth of non-native invasive plants can affect the soundscape of an ecosystem. These altered soundscapes, the acoustic patterns of a landscape through space and time, may provide a key to better observing the hard-to-see physical and biological changes occurring in an ecosystem as they are beginning.

New copper-catalyzed C-H activation strategy

20/04/2024
Inspired by what human liver enzymes can do, chemists have developed a new set of copper-catalyzed organic synthesis reactions for building and modifying pharmaceuticals and other molecules. The new reactions are expected to be widely used in drug discovery and optimization, as well as in other chemistry-based industries.

New beta-decay measurements in mirror nuclei pin down the weak nuclear force

20/04/2024
Scientists have gained insights into the weak nuclear force from new, more sensitive studies of the beta decays of the 'mirror' nuclei lithium-8 and boron-8. The weak nuclear force drives the process of nuclear beta decay. The research found that the properties of the beta decays of lithium-8 and boron-8 are in perfect agreement with the predictions of the Standard Model.

New compound from blessed thistle promotes functional nerve regeneration

20/04/2024
Blessed thistle (Cnicus benedictus) is a plant in the family Asteraceae. For centuries, it has been used as a medicinal herb as an extract or tea, e.g. to aid the digestive system. Researchers have now found a completely novel use for Cnicin. Animal models as well as human cells have shown that Cnicin significantly accelerates axon (nerve fibers) growth.

Shoe technology reduces risk of diabetic foot ulcers

20/04/2024
Researchers have developed a new shoe insole technology that helps reduce the risk of diabetic foot ulcers, a dangerous open sore that can lead to hospitalization and leg, foot or toe amputations.

'Itinerant breeding' in East Coast shorebird species

20/04/2024
A study has found direct evidence of a species -- the American woodcock, a migratory shorebird from eastern and central North America -- that overlaps periods of migration and reproduction, a rare breeding strategy known as 'itinerant breeding.'

Researchers develop a new way to safely boost immune cells to fight cancer

20/04/2024
Researchers explore a cancer immunotherapy treatment that involves activating the immune cells in the body and reprogramming them to attack and destroy cancer cells. This therapeutic method frequently uses cytokines, small protein molecules that act as intercellular biochemical messengers and are released by the body's immune cells to coordinate their response.

Compact quantum light processing

20/04/2024
An international collaboration of researchers has achieved a significant breakthrough in quantum technology, with the successful demonstration of quantum interference among several single photons using a novel resource-efficient platform. The work represents a notable advancement in optical quantum computing that paves the way for more scalable quantum technologies.

'Forgotten city:' the identification of Dura-Europos' neglected sister site in Syria

20/04/2024
The Dura-Europos site in modern-day Syria is famous for its exceptional state of preservation. Like Pompeii, this ancient city has yielded many great discoveries, and serves as a window into the world of the ancient Hellenistic, Parthian, and Roman periods. Yet despite the prominence of Dura-Europos in Near Eastern scholarship, there is another city, only some miles down the Euphrates river, that presents a long-neglected opportunity for study.

Lemur's lament: When one vulnerable species stalks another

20/04/2024
What can be done when one threatened animal kills another? Scientists studying critically endangered lemurs in Madagascar confronted this difficult reality when they witnessed attacks on lemurs by another vulnerable species, a carnivore called a fosa.

Surf clams off the coast of Virginia reappear -- and rebound

20/04/2024
The Atlantic surfclam, an economically valuable species that is the main ingredient in clam chowder and fried clam strips, has returned to Virginia waters in a big way, reversing a die-off that started more than two decades ago. In a comprehensive study of surfclams collected from an area about 45 miles due east from the mouth of the Chesapeake Bay, scientists found the population to be thriving and growing.

Glial hyper-drive for triggering epileptic seizures

19/04/2024
When epileptic patients suffer seizures, their brain is undergoing repetitive and excessive neuronal firing. But what triggers this has stumped scientists for years. Now, researchers have used fluorescence calcium sensors to track astrocytes' role in epileptic seizures, finding that that astrocyte activity starts approximately 20 seconds before the onset of epileptic neuronal hyperactivity.

The Italian central Apennines as a source of CO2

19/04/2024
Tectonically active mountains play an important role in the natural CO2 regulation of the atmosphere. Competing processes take place here: At Earth's surface, erosion drives weathering processes that absorb or release CO2, depending on the type of rock. At depth, the heating and melting of carbonate rock leads to the outgassing of CO2 at the surface. In the central Italian Apennine Mountains, researchers have now investigated and balanced all of these processes in one region for the first time -- using, among others, analyses of the CO2 content in mountain rivers and springs.

The biggest barrier to a vibrant second-hand EV market? Price

19/04/2024
As early adopters of electric vehicles (EVs) trade up for the latest models, the used EV market is beginning to mature in the United States. Yet many potential buyers, particularly low-income drivers, are skeptical of EV's conveniences and are put off by the price.

Weather prediction models can also forecast satellite displacements

19/04/2024
Researchers have found that modern weather models can accurately predict the energy that Earth emits and reflects into space, which directly affects the movements of low Earth-orbiting (LEO) satellites. By leveraging these models, the researchers gained insights into how LEO satellites respond to weather events below, such as tropical cyclones with tall and reflective clouds.

Toxic chemicals from microplastics can be absorbed through skin

19/04/2024
Toxic chemicals used to flame-proof plastic materials can be absorbed into the body through skin, via contact with microplastics, new research shows.

New research defines specific genomic changes associated with the transmissibility of the monkeypox virus

19/04/2024
Scientists have located and identified alterations in the monkeypox virus genome that potentially correlate with changes in the virus's transmissibility observed in the 2022 outbreak.

How reflecting on gratitude received from family can make you a better leader

19/04/2024
New research shows that leaders who take the time to reflect on receiving gratitude from family members can enhance their leadership effectiveness in the office.

Dietary treatment more effective than medicines in IBS
