Researchers have discovered the oldest black hole ever observed, dating from the dawn of the universe, and found that it is 'eating' its host galaxy to death.
Researchers have synthesized the first 2D heavy fermion. The material, a layered intermetallic crystal composed of cerium, silicon, and iodine (CeSiI), has electrons that are 1000x heavier and is a new platform to explore quantum phenomena.
New research shows that behavioral activation therapy is as effective as antidepressant medications in treating symptoms of depression in patients with heart failure.
A team has developed a new measurement method that, for the first time, accurately detects tiny temperature differences in the range of 100 microkelvin in the thermal Hall effect. Previously, these temperature differences could not be measured quantitatively due to thermal noise. Using the well-known terbium titanate as an example, the team demonstrated that the method delivers highly reliable results. The thermal Hall effect provides information about coherent multi-particle states in quantum materials, based on their interaction with lattice vibrations (phonons).
The warming climate has not lead to an expected increase in atmospheric moisture over arid and semi-arid regions of the world. The finding, which has surprised scientists, indicates that some regions may be even more vulnerable to future wildfires and extreme heat than projected.
Researchers have developed a 10-centimeter-diameter glass metalens that can image the sun, the moon and distant nebulae with high resolution. It is the first all-glass, large-scale metalens in the visible wavelength that can be mass produced using conventional CMOS fabrication technology.
Treatment of metastatic disease is responsible for nearly one-third of the decrease in annual deaths from breast cancer from 1975 to 2019, according to a new study.
A discovery from an experiment with magnetic materials and ultrafast lasers could be a boon to energy-efficient data storage.
To function properly, the genetic material is highly organized into loop structures that often bring together widely separated sections of the genome critical to the regulation of gene activity. Scientists now address how these loops can help repress or silence gene activity, with potentially far-reaching effects on human health.
A molecule sourced from funnel web spider venom shows promise as a safe and effective future drug for heart attacks.
A team of scientists discovered the secrets of cell variability in our bodies. The findings of this research are expected to have far-reaching effects, such as improvement in the efficacy of chemotherapy treatments, or set a new paradigm in the study of antibiotic-resistant bacteria.
A study has found some surprising features in two new species of burrowing scorpions, including a very strangely shaped 'tail tip' and some 'sexy' anatomy features. Terrestrial biologists have taken a closer look at two new species of the mysterious Urodacus genus of burrowing scorpions endemic to Australia -- only to find a big difference in their tails compared to other species.
Researchers have discovered a novel treatment to relieve cytokine release syndrome (CRS), a life-threatening inflammation triggered by a serious infection or severe burn. Treatment with a short-acting antibody reduces the inflammatory effects of interleukin-6, a key cytokine in CRS while avoiding the side effects associated with previous longer-acting therapies.
A study has found that older adults who exercise with their spouse achieve lower physical activity levels than older adults without their spouse. In a study of 240 participants in Singapore aged 54 to 72 years old, the researchers also found that those who received personalized feedback on their fitness trackers were more active than those who did not.
Due to the substantial clinical demand for artificial small-diameter vessels (SDVs), numerous commercial products have emerged. However, the majority of existing artificial SDVs lack an endothelial layer, leading to thrombosis. Fabricating artificial SDVs with a consistently uniform endothelial layer and adequate mechanical properties has proven exceptionally challenging. A research team has now induced spontaneous cell assembly and endothelialization through internal pores.
Researchers have achieved a successful contrast agent-free imaging of complex structure of kidney vessels.
The shape, size and optical properties of 3-dimensional nanostructures can now be simulated in advance before they are produced directly with high precision on a wide variety of surfaces. Nanoprobes or optical tweezers with sizes in the nanometre range are now within reach.
Young adults who reported higher stress as adolescents were more likely to have high blood pressure, obesity and other cardiometabolic risk factors as adults, finds new study.
Our latest study shows there are racial/ethnic and socioeconomic disparities in air pollution emissions reductions, particularly in the industry and energy generation sectors. The findings provide a national investigation of air pollution emission changes in the 40 years following the enactment of the Clean Air Act (CAA). Until now, studies have primarily focused on evaluating air pollution disparities at a single time point, focusing on pollutant concentrations instead of emissions. A focus on emissions, however, has more direct implications for regulations and policies. In this study, the researchers used county-level data to evaluate racial/ethnic and socioeconomic disparities in air pollution emissions changes in the contiguous U.S. from 1970 to 2010.
A new study by physicists and neuroscientists describes how connectivity among neurons comes about through general principles of networking and self-organization, rather than the biological features of an individual organism.
