Risk factor is equivalent to lead exposure, study finds — ScienceDaily


A multidecade study of young adults living in the United Kingdom has found higher rates of mental illness symptoms among those exposed to higher levels of traffic-related air pollutants, particularly nitrogen oxides, during childhood and adolescence. Previous studies have identified a link between air pollution and the risk of specific mental disorders, including depression and […]

Preclinical discovery triggers wound healing, skin regeneration — ScienceDaily


Difficult-to-treat, chronic wounds in preclinical models healed with normal scar-free skin after treatment with an acellular product discovered at Mayo Clinic. Derived from platelets, the purified exosomal product, known as PEP, was used to deliver healing messages into cells of preclinical animal models of ischemic wounds. The Mayo Clinic research team documented restoration of skin […]

Awakening ‘ghosts’ in patients with Parkinson’s, a powerful diagnostic tool — ScienceDaily


Scientists are developing a completely new ‘brain stress test’ for evaluating the mental status of patients with Parkinson’s disease, the second most prevalent neurodegenerative disease worldwide. It involves awakening the ‘ghosts’ hidden in specific networks of the brain to predict the onset of hallucinations. “We’re developing something similar to a cardiac stress test, but instead […]

Health chiefs will decide TOMORROW whether under-40s will get alternative to AstraZeneca’s Covid jab


Professor Anthony Harnden said officials were discussing making the change Officials may decide whether under-40s should also be offered an alternative to AstraZeneca‘s coronavirus vaccine in a crunch meeting tomorrow. Professor Anthony Harnden, who sits on No10’s jab advisory panel, said dwindling Covid cases had left officials needing to review current recommendations. Britain’s medical chiefs […]

People of color hardest hit by air pollution from nearly all sources — ScienceDaily


Various studies show that people of color are disproportionately exposed to air pollution in the United States. However, it was unclear whether this unequal exposure is due mainly to a few types of emission sources or whether the causes are more systemic. A new study that models peoples’ exposure to air pollution — resolved by […]

The shape of light changes our vision — ScienceDaily


Vision is a complex process that has been successfully deciphered by many disciplines -physics, biochemistry, physiology, neurology, etc.-: The retina captures light, the optic nerve transmits electrical impulses to the brain, which ultimately generates the perception of an image. Although this process takes some time, recent studies have shown that the first stage of vision, […]

Boarding planes back-to-front DOUBLES Covid exposure risk because people more likely to ‘cluster’


Boarding planes back-to-front DOUBLES the risk that passengers will be exposed to Covid because people are more likely to ‘cluster’ while dealing with their baggage, study finds Major airlines adopted back-to-front boarding to minimize exposure between seated passengers and those entering the plane But a new study finds that boarding an airplane in this method […]

‘Jelly’ that could renew damaged knee joints


An injection of jelly could help treat worn-out joints. Scientists hope the jab, using jelly found in donated umbilical cords, will stimulate the growth of cushioning cartilage once injected into the knees of patients with osteoarthritis. Tests on animals suggest the jelly — called Wharton’s jelly — can potentially reverse damage to joints caused by […]
