Physicists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have for the first time been able to prove a long-predicted but as yet unconfirmed fundamental effect. In Faraday chiral anisotropy, the propagation characteristics of light waves are changed simultaneously by the natural and magnetic-field induced material properties of the medium through which the light travels. The researchers obtained proof that this is the case by conducting experiments using nickel helices at the nanometre scale.

A research team led by Prof. WU Yuejin from the Institute of Intelligent Machines of the Hefei Institutes of Physical Science developed a novel matrix-based slow-release urea (MSU) recently to improve nitrogen use efficiency in rice production, and they assessed the performances of it.

Since the tumour cells of neuroblastoma resemble certain cells in the adrenal glands, a joint research group investigated the cellular origin of these cells and sympathetic neurons during the embryonic development of human adrenal glands. They discovered a previously unknown cell type that might potentially be the origin of the tumour cells.

A new paper published in EPJ Plus by Raj Kumar Sadhu, Weizmann Institute of Science, Rehovot, Israel, takes a step towards a deeper understanding of how cells adhere to each other and their motility.

Atomic-scale optical spectroscopy revealed huge Raman scattering when an atomic point contact is formed between a plasmonic silver tip and a single-crystal silicon surface. The huge Raman scattering allows to observe selectively surface phonons of the single-crystal silicon and to resolve the atomic-scale structures. Atomic point contact Raman scattering paves the way for ultrasensitive atomic-scale vibrational spectroscopy to investigate surface structures.

Scientists make recommendations for a more accurate assessment of controllable biogenic secondary organic aerosols (SOA) formation and its contribution to the total SOA budget.

Children ages two to five who have the most common form of cystic fibrosis have not had any modulator treatments available to them until recently. A new study authored by researchers at Children's Hospital Colorado and published May 6, 2021, in Lancet Respiratory Medicine shows that the CFTR modulator - lumacaftor/ivacaftor - can be safe and well-tolerated for this age range for up to 120 weeks, allowing younger children to begin proactive treatment of CF.

Spinal anesthesia for cesarean section deliveries can cause the mother's blood pressure to drop. To prevent this, physicians routinely administer certain drugs, of which the most common one can lead to undesirable complications in both the mother and the baby. A new study in Chinese Medical Journal shows how a more recent drug that is gaining in use could be the better alternative in terms of reduced complications and also benefit the baby's neurodevelopment.

Early in the COVID-19 pandemic, healthcare systems scrambled to modify patient care processes - particularly when it came to strategies aimed at reducing the risk of hospital-related complications. A look at how one hospital applied its learning health system (LHS) framework to respond to a COVID-19-related increase in hospital-acquired pressure injuries (HAPIs) is presented in the May/June Journal for Healthcare Quality (JHQ), the peer-reviewed journal of the National Association for Healthcare Quality (NAHQ).

They may be tiny weapons, but Brigham Young University's holography research group has figured out how to create lightsabers -- green for Yoda and red for Darth Vader, naturally -- with actual luminous beams rising from them.

Researchers have traced the remaining last steps of the biological pathway that gives oats resistance to the deadly crop disease take-all.

University of Tsukuba researchers tested a new Nike soccer ball used in the English Premier League with a wind tunnel. They found that its aerodynamic properties make it more stable in flight, at the cost of total distance. This work may lead to improvements in sports equipment design.

Machine learning software advances could help anesthesiologists optimize drug dose, potentially improving patient outcomes.

In a new position statement, Alzheimer Europe has issued a call for prioritization of people with dementia and their carers in national COVID-19 vaccination strategies, urging governments to recognize the disproportionate effect of the pandemic on these groups.

Mutations in a protein called GEMIN5 cause developmental delay and loss of coordination in young children.

Informatics experts at the University of Sussex have developed a new computational model that demonstrates a long sought after link between insect and mammalian learning.

Systemic inequalities mean that low-income households in London are more likely to be exposed to higher levels of indoor air pollution, according to a report by UCL researchers.The biggest factors are the quality of housing and the characteristics of the surrounding environment, taking location and levels of outdoor air pollution into account - factors beyond occupants' control.

The dermatological impact of COVID-19 is a burning topic at EADV's 2021 Spring Symposium. New research presented today highlights the effect that stringent hand hygiene during the pandemic has had on hand skin health.

Findings presented at today's EADV 2021 Spring Symposium suggest that an imbalance in gut microbiota (dysbiosis), could play a significant role in the progression of inflammatory skin disease, Hidradenitis Suppurativa (HS). HS is a painful, long-term skin condition, with a chronic and relapsing nature that significantly impacts patients' quality of life.

A new study presents the functions and application of the novel, scalable Regenstrief teaching electronic medical record (tEMR) platform which contains a unique, large, anonymized patient database enabling health professions students to learn how to use health information technology (HIT) to best manage the complex issues presented by real-world patients.
