Scientists reveal mechanism that causes irritable bowel syndrome

17/01/2021
Researchers have identified the biological mechanism that explains why some people experience abdominal pain when they eat certain foods. The finding paves the way for more efficient treatment of irritable bowel syndrome and other food intolerances. The study was carried out in mice and humans.

One small alcoholic drink a day is linked to an increased risk of atrial fibrillation

17/01/2021
A study of nearly 108,000 people has found that people who regularly drink a modest amount of alcohol are at increased risk of atrial fibrillation, a condition where the heart beats in an abnormal rhythm. The study found that, compared to drinking no alcohol at all, just one alcoholic drink a day was linked to a 16% increased risk of atrial fibrillation over an average follow-up time of nearly 14 years.

Scientists offer road map to improve environmental observations in the Indian Ocean

16/01/2021
A group of more than 60 scientists have provided recommendations to improve the Indian Ocean Observing System (IndOOS), a basin-wide monitoring system to better understand the impacts of human-caused climate change in a region that has been warming faster than any other ocean.

Glass frogs living near roaring waterfalls wave hello to attract mates

16/01/2021
A conservationist has discovered that the glass frog Sachatamia orejuela can be added to the list of species that make use of visual cues in response to their acoustic environments. This is the first time a member of the glass frog family (Centrolenidae) has been observed using visual communication in this manner.

Conductive nature in crystal structures revealed at magnification of 10 million times

16/01/2021
In groundbreaking materials research, a team has made a discovery that blends the best of two sought-after qualities for touchscreens and smart windows -- transparency and conductivity.

Tool to distribute limited vaccines equitably

16/01/2021
Researchers have developed a tool that incorporates a person's age and socioeconomic status to prioritize vaccine distribution among people who otherwise share similar risks due to their jobs.

Scientists identify nutrient that helps prevent bacterial infection

16/01/2021
Scientists studying the body's natural defenses against bacterial infection have identified a nutrient -- taurine -- that helps the gut recall prior infections and kill invading bacteria, such as Klebsiella pneumoniae (Kpn). The finding could aid efforts seeking alternatives to antibiotics.

Controlling chemical catalysts with sculpted light

16/01/2021
Using state-of-the-art fabrication and imaging, researchers watched the consequences of adding sculpted light to a catalyst during a chemical transformation. This work could inform more efficient -- and potentially new -- forms of catalysis.

RNA's mysterious folding process

15/01/2021
Using data from RNA-folding experiments, the researchers generated the first-ever data-driven movies of how RNA folds as it is made by cellular machinery. By watching their videos of this folding occur, the researchers discovered that RNA often folds in surprising, perhaps unintuitive ways, such as tying itself into knots.

Target discovered that halts osteoarthritis-type knee cartilage degeneration

15/01/2021
In a mouse study, researchers used nanotechnology and previous knowledge of a protein pathway to significantly reduce knee cartilage degeneration and pain.

Researchers trace geologic origins of Gulf of Mexico 'super basin' success

15/01/2021
The Gulf of Mexico holds huge untapped offshore oil deposits that could help power the U.S. for decades. According to researchers, the basin's vast oil and gas reserves are the result of a remarkable geologic past. Only a fraction of the oil has been extracted and much remains buried beneath ancient salt layers, just recently illuminated by modern seismic imaging.

Breathing easier with a better tracheal stent

15/01/2021
New research is poised to drastically improve the use of tracheal stents for children with airway obstruction. Researchers demonstrate for the first time the successful use of a completely biodegradable magnesium-alloy tracheal stent that safely degrades and does not require removal.

New delivery method promises relief from antipsychotic medication's adverse side effects

15/01/2021
A team of neuroscientists and engineers has created a nasal spray to deliver antipsychotic medication directly to the brain instead of having it pass through the body.

X-Rays surrounding 'Magnificent 7' may be traces of sought-after particle

15/01/2021
Theoretical physicists suggest that never-before-observed particles called axions may be the source of unexplained, high-energy X-ray emissions surrounding a group of neutron stars.

Scientists identify contents of ancient Maya drug containers

15/01/2021
Scientists have identified the presence of a non-tobacco plant in ancient Maya drug containers for the first time. The researchers detected Mexican marigold (Tagetes lucida) in residues taken from 14 miniature Maya ceramic vessels. The vessels also contain chemical traces present in two types of dried and cured tobacco.

Helium nuclei at the surface of heavy nuclei discovered

15/01/2021
Scientists are able to selectively knockout nucleons and preformed nuclear clusters from atomic nuclei using high-energy proton beams. In an experiment the existence of preformed helium nuclei at the surface of several tin isotopes could be identified in a reaction. The results confirm a theory, which predicts the formation of helium clusters in low-density nuclear matter and at the surface of heavy nuclei.

Stuck in a rut: Ocean acidification locks algal communities in a simplified state

15/01/2021
Researchers have found that ocean acidification limits algal communities to a state of low diversity and complexity. Communities grown in waters rich in carbon dioxide (CO2) were dominated by turf algae, and had low biodiversity, ecological complexity and biomass. Communities grown under acidic conditions and then transferred to waters that weren't CO2-enriched increased their biodiversity and complexity, showing that they can recover if CO2 emissions are significantly reduced.

Spreading the sound

15/01/2021
Scientists are studying the motion of sound waves in glassy materials using a new theoretical model and find that they can diffuse like fluids, which may lead to the design of more resilient touchscreens.

Divergences between scientific and Indigenous and Local Knowledge can be helpful

15/01/2021
Divergences between scientific and Indigenous and Local Knowledge can provide a better understanding of why local pastoralists may be willing, or not, to participate in conservation initiatives for carnivores, a study suggests.

Filling a crucial gap in aquafarming: Ion beam breeding to the rescue

15/01/2021
Researchers successfully created a larger strain of zooplankton by creating mutations with a heavy ion beam, which contributes to improving the survival rate and growth of juvenile fish in aquaculture.
