Physicists at MIT and elsewhere have used gravitational waves to observationally confirm Hawking's black hole theorem for the first time.

Melbourne researchers have found that liquid chalk, commonly used in gyms to improve grip, acts as an antiseptic against highly infectious human viruses, completely killing both SARS-CoV-2 (the virus that causes COVID-19) and influenza A viruses.University of Melbourne Professor Jason Mackenzie, a laboratory head at the Peter Doherty Institute of Infection and Immunity (Doherty Institute) wanted to investigate whether liquid chalk stopped SARS-CoV-2 transmission after conversations with his daughter -- an elite rock climber heading to the Tokyo Olympics.

Living cells are constantly exposed to a wide variety of mechanical stresses: heart and lungs must withstand expansion and contraction; our skin must be resistant to tearing whilst retaining elasticity; immune cells are squashy so they can move through the body. "Intermediate filaments" (special protein structures), play an important role here. Researchers at Göttingen University have now measured what determines the properties of individual filaments, and which features only occur through the interaction of filaments in networks.

A relative decline in wealth during midlife increases the likelihood of a cardiac event or heart disease after age 65 while an increase in wealth between ages 50 and 64 is associated with lower cardiovascular risk, according to a new study in JAMA Cardiology.

Study warns that changing climate in the Congo Basin is impacting assessment of the endangered apes

When researchers unexpectedly discovered that small strands of RNA were suppressing the production of certain genes in animals, they suspected they'd stumbled onto something big. More than two decades of research has since confirmed their suspicions, showing that microRNAs have a hand in regulating almost every functional trait in animals and plants. In a new study, researchers provide a roadmap for the most efficient software to use for discovering and detecting microRNAs in plants.

A diet higher in fatty fish helped frequent migraine sufferers reduce their monthly number of headaches and intensity of pain compared to participants on a diet higher in vegetable-based fats and oils, according to a new study.

Eating a diet rich in omega 3 (n-3) fatty acids reduces the frequency of headaches compared with a diet with normal intake of omega 3 and omega 6 (n-6) fatty acids, finds a study published by The BMJ today.

The UK should expand its official list of symptoms for defining covid-19 to prevent cases being missed and help improve the UK's pandemic response, say experts in The BMJ today.

New research being presented at the European Congress of Clinical Microbiology & Infectious Diseases (ECCMID), held online this year, suggests that people with COVID-19 frequently pass it on to their pets. Cats that sleep on their owner's bed seem to be at particular risk of infection.

COVID-19 is common in pet cats and dogs whose owners have the virus, according to new research being presented at the European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) held online this year.

New research presented at this year's European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) taking place online shows that individuals affected by mental illnesses including depression and schizophrenia experience an increased incidence of tuberculosis (TB).

New research being presented at this year's European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) being held online identifies drugs that could potentially be repurposed for the treatment of gonorrhea (Neisseria gonorrhoeae): a sexually transmitted infection which is becoming increasingly resistant to existing antibiotics.

An interdisciplinary team at the Beckman Institute for Advanced Science and Technology determined that older adult women converse more effectively with strangers than their younger counterparts; additionally, communicating with female friends decreases stress hormone levels for women across the lifespan.

Real-world data from the AZ HEROES study show COVID-19 vaccines are highly effective in preventing SARS-CoV-2 infections, and when breakthrough infections do occur, the level of infection and impact of the disease are significantly reduced.

As the pharmacy profession evolves to providing more patient care services, there is a continued need for pharmacy curricula to maintain pace. A recent study suggests Objective Structured Clinical Examinations have value in assessing clinical skills while also giving students learning experiences in community pharmacy settings.

Researchers at Huazhong University of Science and Technology (HUST) propose a scheme to identify and weigh the quantum orbits in strong-field tunneling ionization.

For most patients, the reasons for having a facelift are simple: to "turn back the clock" for a younger and more attractive appearance. Even during the pandemic year 2020, more than 234,000 patients underwent facelift surgery, according to American Society of Plastic Surgeons (ASPS) statistics.

Even the mundane act of swallowing requires a well-coordinated dance of more than 30 muscles of the mouth. The loss of function of even one of these, due to disease or injury, can be extremely debilitating. For these people, nerve stimulation offers a ray of hope to regain some of their lost oral function.

A new study suggests that even when differences in socioeconomic status are taken into consideration, Black people with multiple sclerosis (MS) may be more negatively impacted by the disease than white people with MS. The research is published in the June 30, 2021, online issue of Neurology®, the medical journal of the American Academy of Neurology.
