In a finding that could have key implications for cancer and viral infections in human patients, Australian researchers induced sickness in mice and then stressed them out, showing for the first time that the rodents' white blood cells effectively lost the ability to move, potentially leading to a slowed immune response and an increased vulnerability to further infection.
A new bioluminescent sensor can identify substances that provide the clinical benefits of hallucinogenic drugs for depression, substance use disorder and other conditions without hallucinogens' intense psychoactive side effects, allowing researchers to find potential psychiatric treatments more efficiently.
A new smell testing device developed by U.K. researchers, which uses breakable capsules filled with scented oils, has the potential to replace the "gold standard" scratch-and-sniff tests and help diagnose both chronic neurological conditions and acute respiratory infections that involve an impaired sense of smell, including COVID-19.
Pausing AstraZeneca vaccinations because of suspected links to deadly blood clots may have allowed COVID-19 to spread unchecked and resulted in hundreds of additional deaths among those vulnerable to the virus, vastly outweighing the risk of death from adverse vaccine side effects, according to a new European study.
Certain essential oils have convulsant properties and have been associated with seizures for centuries, though everyday use of oils has generally been considered safe for the average person. But after conducting the largest ever case study of essential oil-related seizures in adults, a group of Indian neurologists have found evidence suggesting their use may not be as safe as we previously assumed.
