| Young workers now value respect over 'fun' perks in the workplace Posted: 22 Jul 2021 01:30 PM PDT Millennials, often referred to as the 'job-hopping generation,' represent a group of young workers who once grabbed the national spotlight with their publicized demands for 'fun' work perks, such as happy hours. However, researchers have discovered today's young workers -- ages 21-34 -- represent a life-stage shift toward placing more value on having respectful communication in the workplace over trendy work perks. |
| AI built to find anti-aging chemical compounds Posted: 22 Jul 2021 01:30 PM PDT Scientists have built an artificial intelligence (AI) model that identifies chemical compounds that promote healthy aging - paving the way towards pharmaceutical innovations that extend a person's lifespan. |
| Investigational magnetic device shrinks glioblastoma in human test Posted: 22 Jul 2021 01:30 PM PDT Researchers shrunk a deadly glioblastoma tumor by more than a third using a helmet generating a noninvasive oscillating magnetic field that the patient wore on his head while administering the therapy in his own home. The 53-year-old patient died from an unrelated injury about a month into the treatment, but during that short time, 31% of the tumor mass disappeared. The autopsy of his brain confirmed the rapid response to the treatment. |
| Eyes wide shut: How newborn mammals dream the world they're entering Posted: 22 Jul 2021 11:20 AM PDT As a newborn mammal opens its eyes for the first time, it can already make visual sense of the world around it. But how does this happen before they have experienced sight? |
| Excess coffee: A bitter brew for brain health Posted: 22 Jul 2021 09:06 AM PDT It's a favourite first-order for the day, but while a quick coffee may perk us up, new research shows that too much could be dragging us down, especially when it comes to brain health. |
| Scientists reverse age-related memory loss in mice Posted: 22 Jul 2021 08:30 AM PDT Scientists have successfully reversed age-related memory loss in mice and say their discovery could lead to the development of treatments to prevent memory loss in people as they age. |
| Parkinson's disease: How lysosomes become a hub for the propagation of the pathology Posted: 22 Jul 2021 08:30 AM PDT Over the last few decades, neurodegenerative diseases became one of the top 10 global causes of death. Researchers worldwide are making a strong effort to understand neurodegenerative diseases pathogenesis, which is essential to develop efficient treatments against these incurable diseases. A team of researchers found out the implication of lysosomes in the spread of Parkinson's disease. |
| Posted: 22 Jul 2021 08:30 AM PDT Geneticists have discovered how a specific genetic mutation (H3K27M) causes a devastating, incurable childhood cancer, known as diffuse midline glioma (DMG), and -- in lab studies working with model cell types -- successfully reverse its effects to slow cancer cell growth with a targeted drug. Their landmark work translates crucial new understanding of the genetics of DMG progression into a highly promising, targeted therapeutic approach and offers significant hope of improved treatments in the future. |
| Scientists discover gene therapy provides neuroprotection to prevent glaucoma vision loss Posted: 22 Jul 2021 08:30 AM PDT A form of gene therapy protects optic nerve cells and preserves vision in mouse models of glaucoma, according to new research. The findings suggest a way forward for developing neuroprotective therapies for glaucoma, a leading cause of visual impairment and blindness. |
| Higher levels of omega-3 acids in the blood increases life expectancy by almost five years Posted: 22 Jul 2021 08:30 AM PDT Researchers have found that omega-3 levels in blood erythrocytes are very good mortality risk predictors. The study used data from a long-term study group, the Framingham Offspring Cohort, which has been monitoring residents of this Massachusetts town, in the United States, since 1971 and concludes that, 'Having higher levels of these acids in the blood, as a result of regularly including oily fish in the diet, increases life expectancy by almost five years.' |
| Wearable devices can reduce collision risk in blind and visually impaired people Posted: 22 Jul 2021 08:29 AM PDT A new randomized controlled trial shows wearing a vibrating collision device can reduce collisions in people who are blind and visually impaired, adding a potential new tool that can be used by these populations in addition to a long cane, to ensure independent travel safety. |
| Professional rugby may be associated with changes in brain structure, study finds Posted: 22 Jul 2021 08:29 AM PDT Participation in elite adult rugby may be associated with changes in brain structure, according to a new study. |
| Scientists develop tougher, safer bicycle helmets using new plastic material Posted: 22 Jul 2021 08:29 AM PDT Researchers have developed a tougher, safer bicycle helmet using a combination of materials. The new helmet prototype has higher energy absorption, reducing the amount of energy transferred to a cyclist's head in the event of an accident and likely lowering the chances of serious injury. |
| Gamma-secretase 'buckles up' to reach its destination Posted: 22 Jul 2021 08:29 AM PDT New research has uncovered the early assembly of gamma-secretase, a protein complex linked to numerous cellular processes including the development of Alzheimer's disease. In a first step, two dimeric subcomplexes are formed, which independently exit the ER and only afterwards assemble into a four-subunit complex. This 'buckle up' mechanism is thought to prevent premature assembly and activity. |
| Study finds calcium precisely directs blood flow in the brain Posted: 21 Jul 2021 04:01 PM PDT Researchers have shown how the brain communicates to blood vessels when in need of energy, and how these blood vessels respond by relaxing or constricting to direct blood flow to specific brain regions. |
| Evidence of sustained benefits of pimavanserin for dementia-related psychosis Posted: 21 Jul 2021 02:27 PM PDT Researchers have published evidence of the sustained benefits of an investigational antipsychotic treatment for people with dementia-related psychosis. |
| Exoskeletons have a problem: They can strain the brain Posted: 21 Jul 2021 02:26 PM PDT Exoskeletons - wearable devices used by workers on assembly lines or in warehouses to alleviate stress on their lower backs - may compete with valuable resources in the brain while people work, canceling out the physical benefits of wearing them, a new study suggests. |
| Older adults just as good as younger people at learning to help others Posted: 21 Jul 2021 07:23 AM PDT Older adults may be slower to learn actions and behaviors that benefit themselves, but new research shows they are just as capable as younger people of learning behaviors that benefit others. |
| Bleak cyborg future from brain-computer interfaces if we're not careful Posted: 20 Jul 2021 08:44 AM PDT The most promising method to achieve real-world BCI applications is through electroencephalography, a method of monitoring the brain's electrical activity. EEG-based BCIs will require a number of technological advances prior to widespread use, but more importantly, they will raise a variety of social, ethical, and legal concerns. Researchers conducted a review of modern commercial brain-computer interface devices and discuss the primary technological limitations and humanitarian concerns of these devices. |
