Precision medicine: Access to real-time genetic testing data impacts prescriber behavior following minimally invasive stent procedure

A Penn study found that access to real-time CYP2C19 genotype results significantly influences prescriber behavior when prescribing antiplatelet drugs after a minimally invasive stent procedure. The use of prasugrel or ticagrelor was higher and clopidogrel lower in the genotyped group compared to the usual care group.

3-D mapping babies' brains

Researchers have developed a new method to precisely map brain folds in premature infants, which could lead to early detection of developmental disorders. The technique uses 3-D imaging and computer algorithms to identify subtle patterns of growth and folding, providing a unique fingerprint for each infant's brain development.

Can't sleep? Could be down to genetics

A large-scale genome-wide association study found that insomnia has a partially heritable basis and a strong genetic link to type 2 diabetes. The study also identified specific gene variants on chromosomes 7 and 9 associated with insomnia.

Flat gallium joins roster of new 2-D materials

Researchers successfully exfoliated gallenene onto various substrates, demonstrating its potential as an efficient metal contact in two-dimensional electronic devices. The method used to create the flat gallium could be explored for other metals and compounds with low melting points.

New method increases life span of donated brain tissue

Researchers at Lund University have developed a new method that extends the viability of donated brain tissue from people with epilepsy to 48 hours. This allows them to study gene therapy treatment and acquire more data from a small number of patients, bringing treatments closer to the patient without direct testing.

Could living at high altitude increase suicide risk? Evidence suggests possible treatments, reports Harvard Review of Psychiatry

A review of research evidence suggests that living at high altitude may increase suicide risk, with studies linking higher altitudes to stronger associations with suicide. Possible treatments for reducing the effects of low blood oxygen on mood and suicidal thoughts are proposed, including supplemental serotonin precursors and creatinine.

Mastering metastable matter

Researchers created metastable states in an artificial quantum many-body system, observing the switching dynamics between two states. They found that thousands of atoms move through quantum tunnelling during the process.

Locked in a forest

A new study finds that reforested areas in the US can absorb significant amounts of carbon, with existing forests capable of sequestering an additional 1-2 billion tons of carbon over 100 years. Researchers analyzed soil profile observations and remote sensing data to determine the rate at which soils absorb carbon.

Experiment sheds new light on prehistoric ocean conditions

A new experiment by Iowa State University's Elizabeth Swanner simulated prehistoric oceans and found that much of the iron was reduced again into its dissolved form despite oxygenation by cyanobacteria. This unexpected result challenges traditional assumptions about how iron-rich sedimentary rocks are formed from ancient oceans.

Metal-organic compounds produces new class of glass

A team of researchers has developed a new class of glass based on metals and organic compounds, with improved glass-forming ability and pliability compared to traditional silica glass. The new metal-organic compound glass, ZIF-62, exhibits superior mechanical properties and optical transmission.
