📰 Scientists crack the code on new vaccine for deadly plague bacteria
Israeli researchers have developed a groundbreaking mRNA-based vaccine that is 100% effective against deadly bacteria, specifically protecting against pneumonic plague. The bacterium Yersinia pestis, which causes plague, is classified as a highly lethal infectious agent and a potential bioterror weapon. The novel vaccine was tested in animals infected with the bacteria, showing full protection within two weeks of a single dose. This study challenges the belief that mRNA vaccines are only effective against viruses, demonstrating the feasibility of developing mRNA vaccines against deadly bacteria. The research paves the way for rapid development of vaccines for bacterial diseases, addressing the global threat of antibiotic-resistant bacteria and improving pandemic preparedness.
📰 Men face double dementia risk if they have a hidden genetic mutation
A recent Australian study led by Monash and Curtin Universities revealed that a hidden genetic mutation in the haemochromatosis (HFE) gene could indicate a man’s increased risk of developing dementia. Men over 70 with two copies of the variant, known as H63D, were found to be at least twice as likely to develop dementia. The study, published in Neurology, analyzed data from the ASPREE trial involving 19,114 healthy older adults. While the genetic variant cannot be changed, potential treatments targeting the affected “brain pathways” may be possible. The study suggests broader testing for the HFE gene in men and further research to understand the mechanisms behind the increased dementia risk in men with the mutation.
📰 Always running late? A mental health condition could be to blame, experts say
Chronic lateness is often attributed to laziness, but experts suggest that a health issue called time blindness may be the cause, affecting a person’s ability to estimate task completion times. Time blindness can lead to missed deadlines, stress, and strained relationships due to difficulties in perceiving time intervals accurately. The condition is linked to executive function issues and is commonly associated with ADHD, affecting skills like working memory and cognitive flexibility. Time blindness can also be present in individuals with autism, OCD, traumatic brain injuries, and other conditions. While there is no formal diagnosis for time blindness, managing it involves minimizing delays, using external devices to track time, and establishing consistent routines to improve time management skills.
📰 Your late-night TV binge could sabotage your brain health, doctor warns
Staying up late to watch TV shows like “Love Island” can lead to sleep deprivation and negative effects on the brain, according to psychiatrist Daniel Amen. Lack of sleep can result in making poor decisions the next day due to the brain not being properly rested. Prioritizing sleep is crucial for memory, energy, focus, and overall brain health. Amen advises going to bed earlier to improve memory and overall cognitive function. He suggests avoiding screens before bed and using blue-light blockers to promote better sleep quality.
📰 Sharpie lip-liner trend goes viral as doctors warn of potential dangers
Some influencers on social media are taking part in the “Sharpie lip liner” trend by using a standard Sharpie on their lips before applying lip gloss or lipstick. Commenters are curious about the specific shade of Sharpie being used, with many seeing it as a cost-effective alternative to traditional lip liners. However, some users have reported experiencing dryness and discomfort after trying the trend, prompting concerns from a dermatologist about the potential health risks associated with using Sharpies on the skin. The chemicals found in permanent markers like Sharpie, such as xylene and toluene, raise worries about absorption and overall health risks. Despite Sharpie’s warning against using their markers on skin, the dermatologist advises those who have participated in the trend to simply stop doing it to avoid potential health issues.
