Theodor Diener, Who Discovered the Tiniest of Infectious Agents, Dies at 102

The cause of a potato disease bedeviled scientists for decades before Dr. Diener figured out that an impossibly small pathogen called a viroid was to blame.

The underrepresentation of women coaches in high-performance sports

In recent years, the popularity of professional women's sports has soared. We've seen the expansion of women's AFL, the creation of the women's Indian Premier League in cricket, as well as things like the 2023 FIFA women's world cup and the 2023 women's rugby league season added to the prime-time television schedule.

A new twist on chirality: Researchers extend the concept of directionality and propose a new class of materials

A new twist on chirality: Researchers extend the concept of directionality and propose a new class of materials

It is often desirable to restrict flows—whether of sound, electricity, or heat—to one direction, but naturally occurring systems almost never allow this. However, unidirectional flow can indeed be engineered under certain conditions, and the resulting systems are said to exhibit chiral behavior.

Fame-seeking mass shooters more likely to plan 'surprise' attacks, finds study

Mass shooters pursuing fame often plan their attacks as "surprises," carefully crafting them in ways that set them apart from previous incidents, which makes them uniquely challenging to prevent.

Maximizing extracellular vesicles: A new protocol on isolation and quantification to optimize patient care

It's a big step forward in using extracellular vesicles (EVs) as a diagnostic tool. Lead study author, J. Nathaniel Diehl, Ph.D., at the UNC School of Medicine, led research showing how a new protocol in handling extracellular vesicles can improve significant diagnostic and therapeutic potential in disease development.

Researchers explore effect of Instagram, TikTok on psychological well-being

Instagram and TikTok are two of the fastest-growing social media outlets in the U.S., offering entertainment and connection to a world-wide community with the ease of a finger swipe. Despite their growing popularity, little research has focused on the association between the specific use of Instagram and TikTok and a person's psychological well-being.

Modeling study shows plastic can drift far away from its starting point as it sinks into the sea

Modeling study shows plastic can drift far away from its starting point as it sinks into the sea

Discarded or drifting in the ocean, plastic debris can accumulate on the water's surface, forming floating islands of garbage. Although it's harder to spot, researchers suspect a significant amount also sinks. In a new study in Environmental Science & Technology, one team used computer modeling to study how far bits of lightweight plastic travel when falling into the Mediterranean Sea. Their results suggest these particles can drift farther underwater than previously thought.

Scientists develop gene silencing DNA enzyme that can target a single molecule

Scientists develop gene silencing DNA enzyme that can target a single molecule

Researchers from the University of California, Irvine have developed a DNA enzyme—or DNAzyme—that can distinguish between two RNA strands inside a cell and cut the disease-associated strand while leaving the healthy strand intact. This breakthrough "gene silencing" technology could revolutionize the development of DNAzymes for treating cancer, infectious diseases and neurological disorders.

Drug industry's carbon impact could be cut by half

In a first-of-its-kind analysis, Cornell researchers and partners at the Clinton Health Access Initiative found that pharmaceutical producers could reduce their environmental impact by roughly half by optimizing manufacturing processes and supply chain networks and by switching to renewable energy sources.

Research into bacteria may lead to new ways of treating infections, improving human health

New research from Nova Southeastern University (NSU) is working towards understanding human infections and unlocking how bacteria "work together" to make these infections much more difficult to treat. Understanding this symbiotic relationship can lead to better ways to treat various ailments.

Viruses could reshuffle the carbon cycle in a warming world

Microbes play important roles in ecosystems, and these roles are changing with global warming. Scientists also now know that most types of microbes are infected by viruses, but they know relatively little about how these viral infections could change how microbes react to warming.

Research team explores the mechanism of tropical expansion under changing climate

Scientific evidence shows that the tropical belt around the middle of the globe is expanding. For years scientists have proposed different mechanisms that might explain this expansion. A team of researchers has now determined that the poleward advancing mid-latitude meridional temperature gradient plays a leading role in the tropical expansion.

Endangered Dupont's lark population declined by 66% after the storm Filomena

Endangered Dupont's lark population declined by 66% after the storm Filomena

A study published in the journal Bird Conservation International warns of a decline of more than 66% in the population of the Dupont's lark (Chersophilus duponti) after the storm Filomena. This meteorological phenomenon was the biggest snowstorm to hit Spain in the last 50 years and was preceded by a week of extreme cold that left temperatures of between -5ºC and -15ºC in the affected areas and records below -33ºC in some localities. The Dupont's lark has recently been listed as an endangered species in Spain.

Thirsty on the moon? Just throw some regolith in the microwave

Thirsty on the moon? Just throw some regolith in the microwave

No matter where we go in the universe, we're going to need water. Thus far, human missions to Earth orbit and the moon have taken water with them. But while that works for short missions, it isn't practical in the long term. Water is heavy, and it would take far too much fuel to bring sufficient water to sustain long-term bases on the moon or Mars. So we'll have to use the water we can extract locally.

Warmer climate could cause Puerto Rico's frogs to croak

The coqui frog is one of Puerto Rico's most iconic animals. It gets its name from its distinctive two-note call, "co-qui," which can be heard throughout the island every night. The males of the species produce these calls to mark their territory and ward away rivals, but scientists can also use them to study the changing climate.
