Symmetry breaking by ultrashort light pulses opens new quantum pathways for coherent phonons

Researchers at Max Born Institute find that ultrafast mid-infrared excitation of electrons in bismuth reduces crystal symmetry, opening new quantum pathways for coherent phonon excitation. This leads to bidirectional atomic motions and oscillations with a frequency different from low-excitation levels.

Enhancing patient care by improving electronic health records: Plan outlines 3 'essential' steps

The University of Virginia Health System has developed a plan to improve the use of electronic health records, reduce clinician workload, and enhance patient care. The plan outlines three 'essential' steps for improving electronic health reforms, including implementing unique personal safety identifiers to streamline operations.

When it comes to satellite data, sometimes more is more

Researchers at Stevens Institute of Technology created a digital platform to enable organizations to share satellite data, accelerating earth science research. The New Observing Strategies Testbed (NOS-T) facilitates complex missions like wildfire spotting and landslides prediction without revealing private information.

Invading insect could transform Antarctic soils

A non-native midge species is significantly increasing rates of plant decomposition, resulting in three to five-fold increases in soil nitrate levels on Signy Island. The midge, Eretmoptera murphyi, is altering soil ecosystems and potentially 'opening the door' for other species to become established.

Russian researchers explain origins of dangerous coronavirus variants

Researchers have identified mechanisms behind the emergence of new and contagious coronavirus variants by analyzing over three million genome sequences. The study found that concordant substitutions occurring at other sites influence the likelihood of a substitution occurring at a specific site, leading to unexpected variant emergence.

Putting hydrogen on solid ground: Simulations with a machine learning model predict a new phase of solid hydrogen

Researchers used a machine learning model to simulate the behavior of hydrogen atoms at high pressures, discovering a new phase that was missed by previous theories and experiments. The discovery has sparked further investigation into the properties of solid hydrogen under extreme conditions.

COVID-19 increased weekday screentime for children: study

A new study found that the COVID-19 pandemic resulted in a significant increase in weekday screen time among school-aged children, with boosts of up to 1.35 hours per day. This finding suggests that children used screens to fill time previously spent at school or participating in extra-curricular activities.

Study shows involuntary displacement of people experiencing homelessness may cause significant spikes in mortality, overdoses and hospitalizations

A new model shows that encampment sweeps, bans and move-along-orders contribute to 15-25% increase in deaths among people experiencing homelessness over a 10-year period. Involuntary displacement is linked to increased overdose deaths, hospitalizations, injection-related infections and hindered access to medications.

People with NAFLD have decreased expression of a liver enzyme needed for medication processing, according to researchers from Indiana University and Eli Lilly

A study from Indiana University School of Medicine found that people with NAFLD have significantly decreased levels of the liver enzyme CYP2C19, which is important for medication processing. This decrease may lead to slower clearance of certain medications and reduced effectiveness of medicines like antidepressants and clopidogrel.
