Researchers resolve magnetic structures of different topological semimetals

Eurekalert - Jul 13 2021 - 00:07
Topological semimetals are one of the major discoveries in condensed-matter physics in recent years. The magnetic Weyl semimetal, in which the Weyl nodes can be generated and modulated by magnetization, provides an ideal platform for the investigation of the magnetic field-tunable link between Weyl physics and magnetism.

Scientists discover nanoclusters effective for cancer in the second near-infrared synergy therapy

Eurekalert - Jul 13 2021 - 00:07
As a minimally invasive method for cancer therapy at precise locations, NIR-induced photothermal therapy (PTT) has drawn extensively attention. The therapeutic mechanism is the use of photothermal agents (PTAs) in the treatment of tumors,and its therapeutic effect happens only at the tumor site where both light-absorbent and localized laser radiation coexist.

DNA reveals the evolutionary history of museum specimens

Eurekalert - Jul 13 2021 - 00:07
Museum specimens held in natural history collections around the world represent a wealth of underutilized genetic information due to the poor state of preservation of the DNA, which often makes it difficult to sequence. An international team, led by researchers from UNIGE and MHN, has optimized a method developed for analyzing ancient DNA to identify the relationships between species on a deep evolutionary scale.

Data science technique helps measure atomic positions more precisely

Eurekalert - Jul 13 2021 - 00:07
Scanning transmission electron microscopy (STEM) allows us to visualize the position of individual atoms inside materials and calculate atomic displacements. However, its precision is limited by measurement noise. In a recent study, scientists from Japan combined a technique from data science with STEM to achieve a remarkable improvement in precision, pioneering a strategy to develop innovative nanomaterials and devices at the atomic scale.

Restless nights: Shelter housed dogs need days to adapt to new surroundings

Eurekalert - Jul 13 2021 - 00:07
Every year, thousands of dogs end up in a shelter in the Netherlands. Experts expect an increase in this number in the upcoming period, when people go back to the office after working from home during the corona crisis. Despite the good care of staff and volunteers, the shelter can be a turbulent experience for dogs. Researchers at Utrecht University investigated if dogs can adapt to their new environment based on their nocturnal activity.

Study finds disparity in pay for female ophthalmologists in Ontario, Canada

Eurekalert - Jul 13 2021 - 00:07
A team led by researchers and clinicians from the Donald K. Johnson Eye Institute, part of the Krembil Research Institute at University Health Network (UHN), studied 22,389 Ontario physicians across three decades and found a significant payment gap between female and male ophthalmologists even after accounting for age, and some practice differences. This disparity was more pronounced among ophthalmologists when compared to other surgical, medical procedural and medical non-procedural specialty groups.

Researchers use prenatal editing in preclinical model to correct lysosomal storage disease

Eurekalert - Jul 13 2021 - 00:07
Researchers at Children's Hospital of Philadelphia (CHOP) have used DNA base editing in a prenatal mouse model to correct a lysosomal storage disease known as Hurler syndrome. Using an adenine base editor delivered in an adeno-associated viral vector, the researchers corrected the single base mutation responsible for the condition, which begins before birth and affects multiple organs, with the potential to cause death in childhood if untreated.
