A new study by Cardiff University in collaboration with the University of Hertfordshire has revealed the huge "secondary burden" placed on those closest to people living with Long Covid.

First-born children have a lower risk of cardiovascular events such as heart attacks and strokes than brothers and sisters born later, but people who are part of a large family with many siblings have an increased risk of these events, suggests the results of a large population study in Sweden, published in the online journal BMJ Open.

Up to a third of patients taking methotrexate - a common treatment for immune mediated inflammatory conditions such as rheumatoid arthritis and psoriasis/psoriatic arthritis - failed to achieve an adequate immune response to mRNA COVID-19 vaccines in a small study accepted for publication in the journal Annals of the Rheumatic Diseases.

Clots in the arteries (arterial thrombosis) are the most common cause of stroke (ischaemic stroke) and have been reported in detail for the first time in young adults who received the Oxford-AstraZeneca covid-19 vaccine in a letter from UK stroke specialists published online in Journal of Neurology Neurosurgery & Psychiatry.

Advanced microscope technology and cutting-edge geological science are giving new perspectives to an old medical mystery: How do kidney stones form, why are some people more susceptible to them and can they be prevented?

Researchers led by Harvard University and The Rockefeller University combine phylogenetic reconstructions and computational behavioral analysis to show that army ant mass raiding evolved from group raiding through the scaling effects of increasing colony size. The transition evolved tens of millions of years ago and is perfectly correlated with a massive increase in colony size.

While some studies suggest female patients treated by female physicians have better outcomes, there does not appear to be a relationship between operator and patient gender and outcome in patients undergoing coronary angioplasty or stenting.

How does the switch to a high-deductible health plan affect children with asthma? A new study suggests that enrollment in a high-deductible health plan (HDHP) may not be associated with changes in asthma medication use or asthma exacerbations when medications are exempt from the deductible.

New study shows cognitive-behavioural therapy for couples to be more effective in alleviating genito-pelvic pain than medical treatment.

It stands to reason that the more one is compensated for performing a task, the greater the incentive to do a good job and the better one feels about doing it.But what if the task is writing an objective review of a company or service? Does the compensation blur the lines of objectivity?

A University of Houston research team is developing an LED bulb that emits less of that troublesome blue light often associated with health issues. The new bulb will rely on the safer violet segment of the visible light spectrum.

"Our results clearly demonstrated that prism adaptation treatment enhances rehabilitation outcome," said Dr. Chen, senior research scientist at Kessler Foundation. "The treated group showed reliably higher scores than the untreated group in total functional independence and cognitive functional independence." She adds, "This is extremely encouraging evidence that integrating prism adaptation into standard of care for people with spatial neglect is beneficial."

Skoltech scientists and their colleagues have published an article describing organic material for a new generation of energy storage systems. The resulted material showed attractive properties: the ability to quickly charge (in less than 1 minute), had high specific capacities (up to ~140 mAh/g), relatively high redox potentials, as well as decent cycling stability (up to 1000 cycles).

Fly ash from coal burning contributes between 37 and 72 percent of the organic carbon particles in the Yangtze River basin

Researchers created an algorithm to identify similar cell types from species -- including fish, mice, flatworms and sponges -- that have diverged for hundreds of millions of years, which could help fill in gaps in our understanding of evolution.

After a wildfire, soils in burned areas often become water repellent, leading to increased erosion and flooding after rainfall events - a phenomenon that many scientists have attributed to smoke and heat-induced changes in soil chemistry. But this post-fire water repellency may also be caused by wildfire smoke in the absence of heat, according to a new paper from the Desert Research Institute (DRI) in Nevada.

Researchers at the University of Arizona recently developed an innovative technique to capture the unused solar energy that illuminates a solar panel. As reported in the Journal of Photonics for Energy (JPE), they created special holograms that can be easily inserted into the solar panel package. This method can increase the amount of solar energy converted by the solar panel over the course of a year by about five percent.

Patterns and drivers of alien plant species invasiveness in Europe identified by an international research team led by Konstanz biologists.

A novel compound similar in structure to the psychedelic drug ibogaine, but lacking its toxic and hallucinogenic effects, has been found to rapidly reverse the effects of stress in mice. Researchers found that a single dose of tabernanthalog (TBG) can correct stress-induced behavioral deficits, including anxiety and cognitive inflexibility, and also promotes the regrowth of neuronal connections and restores neural circuits in the brain that are disrupted by stress.

Researchers have determined that viral particles remaining in the gut long after an initial COVID-19 infection can travel into the bloodstream, instigating the condition called Multisystem Inflammatory Syndrome in Children (MIS-C).
