The fine nose of storks

Researchers discovered that storks are attracted to the smell of freshly cut grass, using their sense of smell to locate food sources. This finding suggests that the sense of smell may play a greater role in other birds than previously thought, contradicting previous assumptions about bird behavior.

Near the toys and the candy bars

A recent study by Dr. Yael Bar-Zeev at Hebrew University of Jerusalem found that tobacco companies are exploiting loopholes to market IQOS products near toys, candy, and schools, targeting young consumers. The audit revealed that 70% of stores selling IQOS were within 300 meters of high schools.

Officers' tone of voice reflects racial disparities in policing

A study published by the American Psychological Association found that police officers' tone of voice conveys less warmth, respect, and ease when speaking to Black male drivers during routine traffic stops. This subtle negativity contributes to a downward cycle of distrust between police and the Black community. The researchers suggest...

Sweet success: CABBI demonstrates first precision breeding of sugarcane with CRISPR-Cas9

Recent innovations by University of Florida researchers at CABBI demonstrate the first successful precision breeding of sugarcane using CRISPR/Cas9 genome editing. This technique allows for precise changes in genes and introduces superior versions, potentially increasing productivity and sustainability.

Teardrop star reveals hidden supernova doom

Astronomers have discovered a rare teardrop-shaped star system that will eventually become a Type Ia supernova. The system, HD265435, is comprised of a hot subdwarf and a white dwarf star orbiting each other closely, with the white dwarf being as heavy as our Sun but slightly smaller than Earth's radius.

Awareness and use of sick leave

Approximately 8 million US employees used FFCRA emergency sick leave within the first 6-8 months. Unmet sick leave needs tripled during the pandemic, with women exhibiting a higher risk, and college graduates, Asian-Americans, and native-born employees being more likely to know about and use the benefit.

New research reveals how the impact of ENSO on Asian-Western Pacific climate would change under global warming

A new study published in the Journal of Climate found that about 23% of uncertainty in WNPAC projection is attributed to El Nino amplitude change, while 77% comes from non-amplitude change related to El Nino decaying pace. The research highlights the importance of considering other El Nino characteristics in climate system projections.

Humans can learn from animals and insects about impact of climate change

A group of researchers studied how animals modify their habitats in response to climate change and found that understanding these modifications can improve predictions of climate change's effects on species. The study highlights the importance of understanding how animals adapt to changing environments, which can inform strategies for ...

Symbionts sans frontieres: Bacterial partners travel the world

A new study reveals that some bacterial symbionts of bivalves have traveled the globe and established partnerships with host species across diverse habitats. This finding challenges previous concepts of symbiont acquisition and highlights the remarkable flexibility in this partnership, which benefits both hosts and symbionts.

Sea-level rise solutions

The study reveals that seawalls can increase flooding and incur significant damages, while strategic flooding areas can absorb increased water and avoid damage. Bay Area communities need to coordinate their approaches to sea-level rise adaptation to find solutions that benefit the whole bay.

New study may offer treatment guidance for MIS-C

A new study has found that treating children and adolescents with multisystem inflammatory syndrome in children (MIS-C) with intravenous immune globulin (IVIG) and glucocorticoids reduces the risk of serious short-term outcomes, including cardiovascular dysfunction. The study analyzed data from over 596 patients and showed a significan...

Childhood lead exposure may adversely affect adults' personalities

A new study by researchers at the University of Texas at Austin found that childhood lead exposure may lead to less mature and less healthy personalities in adulthood. Adults who grew up in areas with higher levels of atmospheric lead had lower levels of conscientiousness and agreeableness, and higher levels of neuroticism.

High-tech toilets could spread antibiotic-resistant superbugs in hospitals, Japanese study suggests

Researchers found that electric toilet water-jet nozzles can harbor multidrug-resistant bacteria, which can be transmitted to patients with weakened immune systems. The study highlights the need for modified hand hygiene practices and toilet disinfection protocols in hospitals to prevent superbug transmission.

Every spot of green space counts

A global study found that urban greenspaces, including parks and gardens, harbor important microbial communities critical for sustaining productive ecosystem services. These microbes also promote effective immunoregulation functions and reduce allergies in humans. However, green spaces can also host fungal parasites and plant pathogens.

Reviewing pressure effects on iron-based high-temperature superconductors

The review highlights the use of pressure as a versatile method to explore new materials and gain insight into high-temperature superconductor mechanisms. Iron-based superconductors exhibit a relatively high transition temperature, with research efforts focusing on raising this temperature through pressure-induced effects.
