For The Better

Researchers modeled what happens to respiratory droplets when they come in contact with wet masks. Their results show that damp masks are still effective at stopping these droplets from escaping the mask and being atomized into smaller, easier-to-sprea…

Poor sleep in the over 50s is linked to more negative perceptions of aging, which in turn can impact physical, mental and cognitive health, new research has revealed. A study found that people who rated their sleep the worst also felt older, and percei…

Astronomers have discovered two previously invisible galaxies 29 billion light-years away. Their discovery suggests that up to one in five such distant galaxies remain hidden from our telescopes, camouflaged by cosmic dust. The new knowledge changes pe…

Identical twins share the same DNA, but one twin can suffer from type 2 diabetes while the other twin does not develop the disease. Researchers have now discovered that there are differences in gene activity in twins where only one sibling had develope…

Researchers have developed a wearable device to detect and reverse an opioid overdose. The device, worn on the stomach like an insulin pump, senses when a person stops breathing and moving, and injects naloxone, a lifesaving antidote that can restore r…

Scientists have succeeded in creating an experimental model of an elusive kind of fundamental particle called a skyrmion in a beam of light.

The question of the causes of species extinction confronts science with complex tasks.

A white dwarf star that completes a full rotation once every 25 seconds is the fastest spinning confirmed white dwarf, according to a team of astronomers.

Since the discovery of quasicrystals (QCs), solids that mimic crystals in their long-range order but lack periodicity, scientists have sought physical properties related to their peculiar structure. Now, an international group of researchers report a l…

Researchers explain why digital teaching cannot replace face-to-face teaching in university education, but can certainly be seen as a complementary tool. The future of teaching and learning may lie in so-called blended learning, a mix of face-to-face a…

To successfully cooperate or compete with other people in everyday life, it is important to know what the other person thinks, feels, or wants. Researchers have explored which strategies people use to understand other people.

Volcanic gases are helping researchers track large-scale movements in Earth’s deep interior. Scientists have discovered anomalous geochemical compositions beneath Panama.

By integrating multiple sensory inputs, a loop of mutual inhibition among a small set of neurons allows worms to switch between long-lasting behavioral states.

A combined experimental and computational study shows promising results for a new class of catalysts producing ammonia under mild conditions.

When it comes to your health, being willing to give social support to your spouse, friends and family may be just as important as receiving assistance, a new study suggests.

The gold complex auranofin has traditionally been used for treating rheumatism but is also being evaluated as a treatment for certain forms of cancer. Researchers now show that other molecules that inhibit the same biological system have a more specifi…

Researchers have developed an innovative technique to track microbes and understand the various ways they process soil carbon, findings that add to our knowledge of how bacteria contribute to the global carbon cycle.

It sounds like modern-day alchemy: Transforming sugar into hydrocarbons found in gasoline. But that’s exactly what scientists have done. Researchers report harnessing the wonders of biology and chemistry to turn glucose (a type of sugar) into olefins (…

Eliminating old, dysfunctional cells in human fat also alleviates signs of diabetes, researchers report. The discovery could lead to new treatments for Type 2 diabetes and other metabolic diseases.

Quantum dots have many possible applications, but they are limited by their tendency to blink off at random intervals. Chemists have come up with a way to control this unwanted blinking without requiring any modification to the formulation or the manuf…
