1 week agoPsychology says older adults who stay tech-savvy into their 70s and 80s aren't just 'good with computers' - they display a specific type of cognitive flexibility that actually protects against age-related decline - Silicon Canals
Regular technology use may significantly reduce the risk of cognitive decline in older adults.

3 weeks agoThe gut microbiome may influence brain aging, mouse study suggests
Young, two-month-old lab mice housed with older, 18-month-old mice showed really impaired cognition. Researchers exposed young mice raised in a sterile, microbe-free environment to gut bacteria from old mice, causing the younger animals to perform worse on cognitive tests, as if they had prematurely aged, just like the cohoused mice.

Anyone living with schizophrenia understands the true limitations of current treatment options. Antipsychotics remain the single leading treatment for the disorder, and they are riddled with undesirable side effects. Weight gain, tardive dyskinesia, and excessive drowsiness are a few. Much research is devoted to expanding the range of medication options, and few academics have pursued other avenues. However, there is a possibility that treatment for schizophrenia can be approached through cellular methods if long-term research validates early signs of hope.

I received an email recently that claims Wal-Mart senior management has been calling mandatory meetings for the company's employees in which the employees are told they "cannot" vote for the Obama-Biden ticket "or any other employee-friendly, union-friendly candidates for political office". It's not an urban legend, according to the sources I checked. This makes me so angry I just boil. When it comes to the Constitution, I am a rabid supporter.

1 month agoDaily briefing: Tumours use neurons as hotline to the brain
Tumours lure and then hijack nearby sensory neurons to boost their own growth. The cancer cells use these neurons to send a signal to the brain that subdues the activity of immune cells around the tumour, which allows it to grow unchecked. When researchers deactivated these neurons in mice with lung cancer, they saw "a huge, dramatic reduction" in tumour growth - more than 50% - says cancer immunologist and study co-author Chengcheng Jin.
