Sex hormones determine how well anesthesic works in men and women

Almost 25 years since scientists first identified the difference in anesthetic sensitivity between males and females, new research suggests that sex hormones make men more responsive to this state of unconsciousness – and women far less so.Continue Rea… Continue reading Sex hormones determine how well anesthesic works in men and women

“Chemical chaperone” improves Alzheimer’s signs in early & late disease

Treatment with a supplementary 'chemical chaperone' has been shown to reduce protein plaques and improve cognitive performance in Alzheimer's disease

A new study has found that treatment with a ‘chemical chaperone’ assists in reducing the accumulation of protein plaques and restores cognitive functioning in mouse models of Alzheimer’s disease. The findings could lead to novel treatments to help treat this debilitating disease.

Stress triggers a neuron during sleep that upends healthy slumber

We all know that stress can rob you of a good night’s sleep, but it’s more than just racing thoughts behind it. For the first time, scientists have identified how stress fires up brain cells at the wrong time during sleep stages, causing interrupted sl… Continue reading Stress triggers a neuron during sleep that upends healthy slumber

Common local anesthetic may be effective against head and neck cancers

A new study has uncovered how the commonly used local anesthetic drug, lidocaine, activates bitter taste receptors to exert an anti-cancer effect in head and neck cancers. Given its low cost and ready availability, the drug could easily be incorporated… Continue reading Common local anesthetic may be effective against head and neck cancers

AI system does better than humans at identifying odors

A new computer-trained scent model has done better than humans at identifying odors. In analyzing 500,000 potential odor molecules that had never before been synthesized, it also handily did work that would take 70 person-years to complete.Continue Rea… Continue reading AI system does better than humans at identifying odors

Staying focused is not down to willpower, but some tiny neurons

While completing a task with other distractions can seem like it’s a battle of willpower, scientists have discovered how it’s not you but your brain that keeps you on the right track. Or at least it tries to.Continue ReadingCategory: Medical, ScienceTa… Continue reading Staying focused is not down to willpower, but some tiny neurons

Targeted brain stimulation improves memory in traumatic brain injury

Memory is commonly affected following a traumatic brain injury and may be long-lasting or even permanent. A new study has found that AI-guided electrical brain stimulation in people with moderate-to-severe traumatic brain injury may successfully treat … Continue reading Targeted brain stimulation improves memory in traumatic brain injury

Plant-based insulin derived from lettuce, can be taken orally

Animal cells share some qualities with plant cells, but one key feature ours lack is a rigid cell wall. While this provides structure for plants, it’s also something scientists are increasingly looking at for use in new materials, cellulose technology … Continue reading Plant-based insulin derived from lettuce, can be taken orally

Newly discovered bacterial partnership implicated in dental cavities

For the first time, researchers have found a bacterium that forms superstructures when it gets caught in sticky traps made by other bacteria, helping it erode enamel and form cavities. The finding could lead to new ways to keep our teeth clear of the i… Continue reading Newly discovered bacterial partnership implicated in dental cavities
