Scientists reveal mechanism that causes irritable bowel syndrome

Science Daily - 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

Science Daily - 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.

NASA test of mega Moon rocket engines cut short

The Hindu:Science - 17/01/2021
The “hot-fire” test at the Stennis Space Center in Mississippi was supposed to last a little over eight minutes — the time the engines would burn in flight — but they shut down just over a minute into the burn.

Tiny worms can make complex travel decisions when hitch-hiking: IISc study

The Hindu:Science - 16/01/2021
This was one of the key findings by two researchers from the Centre for Ecological Sciences (CES) at the Indian Institute of Science who studied how microscopic worms called nematodes that live in fig trees hitch a ride on fig wasps so that they can move from one tree to another

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

Science Daily - 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

Science Daily - 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

Science Daily - 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

Science Daily - 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

Science Daily - 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

Science Daily - 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

Science Daily - 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

Science Daily - 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

Science Daily - 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

Science Daily - 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

Science Daily - 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.
