More belly weight increases danger of heart disease even if BMI does not indicate obesity

Research on how obesity impacts the diagnosis, management and outcomes of heart and blood vessel disease, heart failure and arrhythmias is summarized in a new statement.Waist circumference, an indicator of abdominal obesity, should be regularly measured as it is a potential warning sign of increased cardiovascular disease risk.Interventions that lead to weight loss improve risk factors yet may not...

Nanofiltration membranes to treat industrial wastewater from heavy metals

NUST MISIS scientists together with Indian colleagues from Jain University and Sri Dharmasthala Manjunatheshwara College presented innovative membranes for the complete removal of heavy metals from industrial wastewater. The special nanostructure of zinc-modified aluminum oxide made it possible to remove arsenic and lead from water with an efficiency of 87% and 98%, respectively. The results of...

Neuro-researchers find repetitive head impacts can result in functional brain impairments

Neuroscience researchers at Mayo Clinic Orthopedics and Sports Medicine in Rochester, Minnesota, U.S., the Health and Technology District and Simon Fraser University (SFU) in Surrey, British Columbia, Canada have published the latest results of their ongoing multi-year hockey concussion study examining changes in subconcussive cognitive brain function in male youth ice hockey players. The research...

New research data on the regulation of hormone-dependent breast cancer

Notch proteins are key regulators of growth and differentiation of both normal and cancer cells. Researchers in Turku, Finland, have now demonstrated that the activities of distinct Notch family members are modified differently by phosphorylation. These results can be used in the development of new cancer treatments, especially for hormone-dependent breast cancer.

New research finds advanced shoe technology reduces top race times for elite athletes

A new paper is the first to study the effects of advanced shoe technology on the performance of elite long-distance runners. Researchers found that the new footwear, featuring lightweight foam and a rigid plate in the midsole, significantly reduced race times for both men and women. Female runners benefited most, shaving about 2 minutes and 10 seconds off marathon times, which represents a 1.7...

Next generation of swimming biobots can self-train, showing striking speed and strength

Researchers at the Institute for Bioengineering of Catalonia (IBEC) led by Samuel Sanchez achieve a breakthrough in the field of biological robots by developing new biobots based on muscle cells that can swim at unprecedented velocities. These biobots also react to electrical stimuli and exert surprising forces thanks to their self-training with a 3D printed smart skeleton, opening the door to a...

Photoexpansion: Bio-based polyesters hard film

A phenomenon of "photoexpansion" in hard plastic films with a high glass transition temperature in the dry state was established, which was essentially different from very soft actuators, such as elastomers or gels. The photoexpanding hard actuators were expected to apply in the wide fields because they do not contain vaporable matters such as solvents and were much more thermoresistant than...

Plant provenance influences pollinators

Insect decline poses challenges for the pollination of wild and cultivated plants. Landscape ecologists from Münster University have now discovered that the diversity of insects that interact with plant communities is influenced not only by plant species but also by the geographical provenance of seeds. The results of the study have been published in the "Journal of Applied Ecology".

Political polarization: Often not as bad as we think

As politics grows increasingly polarized, a new global study finds people often exaggerate political differences and negative feelings of those on the opposite side of the political divide, and this misperception can be reduced by informing them of the other side's true feelings. The study replicates earlier research in the United States, finding the phenomenon to be generalizable across 25...

Progression of cardiac hypertrophy in dialysis patients can be retarded by drugs

Patients with chronic kidney dysfunction frequently develop thickening of the heart muscle, so-called left ventricular hypertrophy. Haemodialysis patients have a number of risk factors for developing this form of cardiac hypertrophy. One of those is elevated levels of the protein Fibroblast Growth Factor 23 (FGF23), and these levels increase as kidney function deteriorates. However, FGF23 can be...

Properties of chromium tribromide show path to innovative electronic devices

Two-dimensional (2D) materials with a single-layer thickness retaining magnetic order in atomically thin limit began to increase their scientific and technological significance after the successful synthesis of graphene and later investigations of van der Waals materials. CrBr3 has been known since the 60s as a van der Waals ferromagnet.
