This may prime their defenses against our immune system and increase their […]

What makes a feel-good film feel good? First large-scale study of feel-good films and their audiences — ScienceDaily


“Feel-good films” are usually dismissed by film critics as being sentimental and without intellectual merit. But their popularity with audiences, who seek them out precisely because of their “feel-good” qualities, tells a more favorable story. Now, for the first time, this popular movie genre has been examined scientifically. A new study from the Max Planck […]

DR MICHAEL MOSLEY: Can eating too much be a sign your body lacks nutrients?


For most people, the past 12 months have been really tough, but some businesses have thrived — it seems 2020 was a fantastic year for supplement manufacturers, with nearly £500 million in UK sales, up a record 14 per cent compared with 2019.

How do different parts of the brain communicate with each other during learning and memory formation? A new study by researchers at the University of California San Diego takes a first step at answering this fundamental neuroscience question. The study was made possible by developing a neural implant that monitors the activity of different parts […]

Goethe University researchers investigate oxidative stress in mice — ScienceDaily


Originally, oxygen radicals — reactive oxygen species, or ROS for short — were considered to be exclusively harmful in the body. They are produced, for example, by smoking or UV radiation. Because of their high reactivity, they can damage many important molecules in cells, including the hereditary molecule DNA. As a result, there is a […]

Understanding molecular interactions might be a target of precision medicine — ScienceDaily


Scientific studies rarely focus on long non-coding RNA molecules (lncRNAs), even though they potentially regulate several diseases. The role of several lncRNAs in anti-viral inflammatory response regulation has recently been reported. Considering their significant regulatory function in immune response, researchers from the Azrieli Faculty of Medicine of Bar-Ilan University sought to identify lncRNAs co-expressed with […]

In mice, therapy based on natural molecules improves lung function — ScienceDaily


A new treatment is among the first known to reduce the severity of acute respiratory distress syndrome caused by the flu in animals, according to a new study. Tests in mice infected with high doses of influenza showed that the treatment could improve lung function in very sick mice and prevent progression of disease in […]

Household aerosols now release more harmful smog chemicals than all vehicles in the country — ScienceDaily


Aerosol products used in the home now emit more harmful volatile organic compound (VOC) air pollution than all the vehicles in the UK, new research shows. A new study by the University of York and the National Centre for Atmospheric Science reveals that the picture is damaging globally with the world’s population now using huge […]

Researchers identify protein produced after stroke that triggers neurodegeneration — ScienceDaily


Researchers with the Peter O’Donnell Jr. Brain Institute at UT Southwestern have identified a new protein implicated in cell death that provides a potential therapeutic target that could prevent or delay the progress of neurodegenerative diseases following a stroke. Scientists from the departments of pathology, neurology, biochemistry, and pharmacology at UTSW have identified and named […]

Women’s fertility may decline with age due to impaired RNA levels — ScienceDaily


Age may adversely affect women’s fertility by impairing levels of RNA molecules which in turn alter the function of genes involved in key biological pathways during the final maturation stage of a human egg cell, according to the findings of a new study published today in the journal Aging Cell. Researchers from the Centre for […]

Impaired drainage also may play a role in Alzheimer’s in people — ScienceDaily


Experimental Alzheimer’s drugs have shown little success in slowing declines in memory and thinking, leaving scientists searching for explanations. But new research in mice has shown that some investigational Alzheimer’s therapies are more effective when paired with a treatment geared toward improving drainage of fluid — and debris — from the brain, according to a […]

How deadly is India’s Covid variant and is it REALLY behind explosion of cases?


India‘s coronavirus variant may not be fully to blame for the country’s devastating second wave, according to scientists who say a ‘perfect storm’ of Covid complacency, a disregard for social distancing and lack of preparedness by the Government has fuelled the crisis.  Doctors on the frontline claim the B.1.617 strain is responsible for the raging second […]

Stress slows the immune response in sick mice — ScienceDaily


The neurotransmitter noradrenaline, which plays a key role in the fight-or-flight stress response, impairs immune responses by inhibiting the movements of various white blood cells in different tissues, researchers report April 28th in the journal Immunity. The fast and transient effect occurred in mice with infections and cancer, but for now, it’s unclear whether the […]
