| Only alcohol -- not caffeine, diet or lack of sleep -- might trigger heart rhythm condition Posted: 24 Nov 2021 12:41 PM PST New research that tested possible triggers of a common heart condition, including caffeine, sleep deprivation and sleeping on the left side, found that only alcohol use was consistently associated with more episodes of the heart arrhythmia. |
| Morning exposure to deep red light improves declining eyesight Posted: 24 Nov 2021 12:41 PM PST Just three minutes of exposure to deep red light once a week, when delivered in the morning, can significantly improve declining eyesight, finds a pioneering new study. |
| Latte lovers rejoice! Study reveals drinking coffee could lower the risk of Alzheimer’s disease Posted: 23 Nov 2021 10:14 AM PST Good news for those of us who can't face the day without their morning flat white: a long-term study has revealed drinking higher amounts of coffee may make you less likely to develop Alzheimer's disease. |
| Can we perceive gender from children's voices? Posted: 23 Nov 2021 10:13 AM PST Researchers report developing a database of speech samples from children ages 5 to 18 to explore two questions: What types of changes occur in children's voices as they become adults, and how do listeners adjust to the enormous variability in acoustic patterns across speakers? When they presented listeners with both syllables and sentences from different speakers, gender identification improved for sentences. They said this supports the stylistic elements of speech that highlight gender differences and come across better in sentences. |
| Taking it easy as you get older? Wrong Posted: 22 Nov 2021 02:27 PM PST A team of evolutionary biologists and biomedical researchers lay out evolutionary and biomedical evidence showing that humans, who evolved to live many decades after they stopped reproducing, also evolved to be relatively active in their later years. The researchers say that physical activity later in life shifts energy away from processes that can compromise health and toward mechanisms in the body that extend it. They hypothesize that humans evolved to remain physically active as they age -- and in doing so to allocate energy to physiological processes that slow the body's gradual deterioration over the years. This guards against chronic illnesses such as cardiovascular disease, type 2 diabetes, and even some cancers. |
| How people understand other people Posted: 22 Nov 2021 10:54 AM PST To successfully cooperate or compete with other people in everyday life, it is important to know what the other person thinks, feels, or wants. Researchers have explored which strategies people use to understand other people. |
| Repurposed ALS drug shows promise in mouse model of rare childhood genetic disorder Posted: 19 Nov 2021 12:55 PM PST Riluzole, a drug approved to treat amyotrophic lateral sclerosis (ALS), a disease affecting nerve cells controlling movement, could slow the gradual loss of a particular brain cell that occurs in Niemann-Pick disease type C1 (NPC1), a rare genetic disorder affecting children and adolescents, suggests a study in mice. |
| Posted: 19 Nov 2021 12:55 PM PST Speech sounds elicit comparable neural responses and stimulate the same region in the brain of humans, macaques and guinea pigs, researchers report. The finding could help pave the way for better understanding and diagnosis of auditory processing deficits. |
| Posted: 18 Nov 2021 05:37 PM PST New highly sensitive quantum sensors for the brain may in the future be able to identify brain diseases such as dementia, ALS and Parkinson's, by spotting a slowing in the speed at which signals travel across the brain. |
