According to a recent Finnish study, higher levels of moderate and vigorous physical activity can curb arterial stiffening already in childhood. However, sedentary time or aerobic fitness were not linked to arterial health. The results, based on the ongoing Physical Activity and Nutrition in Children (PANIC) Study conducted at the University of Eastern Finland, were published in the Journal of Sports Sciences.
Graphene consists of carbon atoms arranged in a chicken-wire like pattern. This one-atom-thick material is famous for its many extraordinary properties, such as extreme strength and remarkable capability to conduct electricity. Since its discovery, researchers have looked for ways to further tailor graphene through controlled manipulation of its atomic structure. However, until now, such modifications have been only confirmed locally, because of challenges in atomic-resolution imaging of large samples and analysis of large datasets.
New study by the ICTA-UAB shows that residents and visitors highlight the natural and biodiversity values of the Llobregat Delta, in Barcelona.
A new study undertaken by researchers at the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) supports protestors' concerns about damage to the Llobregat Delta in airport expansion plans.
New classes of drugs are biologic disease-modifying anti-rheumatic drugs (bDMARDs) and Januskinase inhibitors (JAKi). At the 2021 EULAR congress, Strangfeld and colleagues shared new data assessing the effects of these medications on the risk of serious infections in elderly people with RA. RA is an inflammatory autoimmune disease that causes pain, swelling, and stiffness in the joints, but it also affects other organ systems through underlying systemic inflammation, causing for example cardiovascular diseases or fatigue.
Professor Konstantin Arutyunov of the HSE Tikhonov Moscow Institute of Electronics and Mathematics (MIEM HSE), together with Chinese researchers, has developed a graphene-based mechanical resonator, in which coherent emission of sound energy quanta, or phonons, has been induced. Such devices, called phonon lasers, have wide potential for application in information processing, as well as classical and quantum sensing of materials.
Geologic activity on Earth appears to follow a 27.5-million-year cycle, giving the planet a "pulse," according to a new study published in the journal Geoscience Frontiers.
The visual thalamus is classically known to relay visual stimuli coming from the retina to the cerebral cortex. Researchers from the Max Planck Institute of Neurobiology now show that although neurons in the mouse visual thalamus connect to both eyes, they establish strong functional connections only with one retina. These results settle partly contradictory results of earlier studies and demonstrate how important it can be to complement structural data with functional analyses.
BIRMINGHAM, Ala. - A comprehensive health-screening program in rural northern KwaZulu-Natal, South Africa, has found a high burden of undiagnosed or poorly controlled non-communicable diseases, according to a study published in The Lancet Global Health.
Researchers found that four out of five women over the age of 30 were living with a chronic health condition, and that the HIV-negative population and older people -- especially those over 50 -- bore the higher burden of undiagnosed or poorly controlled non-communicable diseases such as diabetes and hypertension.
By combining satellite data and digital models, the researchers have shown that coastal overtopping, and consequently the risk of flooding, is set to further accelerate over the 21st century, by up to 50-fold under a high emission global warming scenario, especially in the tropics. This increase is principally caused by a combination of sea level rise and ocean waves.
Scientists from the Walter Reed Army Institute of Research and Naval Medical Research Center partnered with researchers at the University of Pennsylvania and Acuitas Therapeutics to develop a novel vaccine based on mRNA technology that protects against malaria in animal models, publishing their findings in npj Vaccines.
Cancer cells can develop resistance to therapy through both genetic and non-genetic mechanisms. But it is unclear how and why one of these routes to resistance prevails. Understanding this 'choice' by the cancer cells may help us devise better therapeutic strategies. Now, the team of Prof. Jean-Christophe Marine (VIB-KU Leuven Center for Cancer Biology) shows that the presence of certain stem cells correlates with the development of nongenetic resistance mechanisms. Their study is published in the prestigious journal Cancer Cell.
Two routes to resistance
Southeast Asian monsoon region falls in the warm and humid tropics modulated by Asian monsoon. It is home to nearly 15% of the world's tropical forests and one of the biodiversity hotspots in the world.
With the unprecedented urbanization and population growing rate, water scarcity issues have already posed a serious challenge for sustainable development in Southeast Asian monsoon region. However, the impact of anthropogenic forcing, such as greenhouse gases and anthropogenic aerosols, on extreme drought events in the region is still unclear.
Tissue-engineering scaffolds built around ultrashort peptides provide a new platform for studying bone regeneration in the lab.
The peptides developed at KAUST self-assemble into a cartilage-like hydrogel that mimics the natural matrix that underpins bone formation in the body. Its physiologically relevant properties enable this cell-friendly biomaterial to support the growth and development of bone marrow precursor cells. It also enables tubular blood vessels to take shape, which is a critical part of bone health and repair.
Living beings are continuously exposed to harmful agents, both exogenous (ultraviolet radiation, polluting gases, etc.) and endogenous (secondary products of cellular metabolism) that can affect DNA integrity. That's why cells are endowed with a series of molecular mechanisms whose purpose is to identify and signpost possible damage to the genetic material for speedy repair. These mechanisms are precisely regulated because they are key to cell survival. In extreme situations of massive and irreparable damage, cells enter a phase of controlled dismantling called "programmed cell death".
