A new study reported that SARS-CoV-2, the virus that causes COVID, can infect dopamine neurons in the brain and trigger senescence -- when a cell loses the ability to grow and divide. The researchers suggest that further research on this finding may shed light on the neurological symptoms associated with long COVID such as brain fog, lethargy and depression.
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.

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.
AI is a powerful force. What if we used it for good? In this year's roundup, I'm celebrating the visionary philanthropy leaders making AI for humanity a reality.
Researchers have developed a bio-logger for seabirds that enables long-term observation of rare behaviors. The bio-logger employs low-power depth sensors and accelerometers to identify rare behavior using a light-weight outlier detection model and records the behavior in a 5-min video. Observations using the bio-loggers on Streaked Shearwaters revealed novel aspects of head-shaking and foraging strategies. This approach will enable a wider range of animal behaviors in various environments to be observed.

Federal prosecutors say the Baltimore Police Department has completed its first official step toward fulfilling a series of court-ordered reforms
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.
Researchers have created a new way to detect 'forever chemical' pollution in water, via a luminescent sensor.
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...

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.
