Astronomers discover heavy elements after bright gamma-ray burst from neutron star merger

An international team of astronomers — including Clemson University astrophysicist Dieter Hartmann — obtained observational evidence for the creation of rare heavy elements in the aftermath of a cataclysmic explosion triggered by the merger of two neutron stars. The massive explosion unleashed a gamma-ray burst, GRB230307A, the second brightest in 50 years of observations and about 1,000 times brighter than a typical gamma-ray burst. GRB230307A was first detected by NASA’s Fermi Gamma-Ray Space Telescope on March 7, 2023. Using multiple space- and ground-based ...

A new plant’s name that tells a story

A new species and genus of fairy lantern, tiny glass-like white plants that feed on fungi, has been discovered in Japan. In the country renowned for its extensive flora research, the discovery of a new plant genus is extremely rare and has not occurred in almost 100 years. Fairy lanterns, or Thismiaceae as they are known to botany, are very unusual plants found mainly in tropical but also in subtropical and temperate regions. First of all, they are not green and do not engage in photosynthesis, but rather feed on fungal mycelia in the ground. As a consequence, they are often hidden under fallen leaves and only for a brief period produce above-ground flowers that look like glasswork. The ...

Study detects cognitive changes in older drivers using in-vehicle sensors

An estimated 4 to 8 million older adults with mild cognitive impairment are currently driving in the United States, and one-third of them will develop dementia within five years. Individuals with progressive dementias are eventually unable to drive safely, yet many remain unaware of their cognitive decline. Currently, screening and evaluation services for driving can only test a small number of individuals with cognitive concerns, missing many who need to know if they require treatment. Nursing, engineering and neuropsychology researchers at Florida Atlantic University are testing and evaluating a readily and rapidly available, unobtrusive in-vehicle sensing ...

Astronomers reveal a new link between water and planet formation

Researchers have found water vapour in the disc around a young star exactly where planets may be forming. Water is a key ingredient for life on Earth and is also thought to play a significant role in planet formation, yet, until now, astronomers have never been able to map how water is distributed in a stable, cool disc — the type of disc that offers the most favourable conditions for planets to form around stars. For the first time, astronomers have weighed the amount of water vapour around a typical planet-forming star.     The new findings were made possible thanks to the Atacama Large Millimeter/submillimeter Array (ALMA) - a collection of telescopes ...

Plant biologists identify promising new fungicides

A promising new fungicide to fight devastating crop diseases has been identified by researchers at the University of California, Davis. The chemical, ebselen, prevented fungal infections in apples, grapes, strawberries, tomatoes and roses and improved symptoms of pre-existing fungal infection in rice. Fungal pathogens account for almost a quarter of global crop losses. In the United States, these losses amount to around $150 billion per year. However, fungicide development has been slow for the past 50 years, largely because researchers have had difficulty identifying molecular pathways to target. In a new study published Feb. 29 in ...

Researchers uncover a potential genetic marker associated with better survival outcomes in patients with head and neck cancer

FINDINGS Researchers from the UCLA Health Jonsson Comprehensive Cancer Center show for the first time that a gene usually linked to giant axonal neuropathy, a rare and severe neurological condition, also plays a role in inhibiting aggressive tumor cell growth in head and neck cancers. The team found when the specific genetic variant (GAN gene exon 8 SNP T allele) of the GAN gene isn't present, it leads to the production of certain proteins that make cancer cells more likely to spread and become resistant to treatment. These findings suggest that the presence of the genetic variant and higher expression of the GAN gene product gigaxonin may contribute ...
