Immune activity shortly after surgery holds big clue to recovery rate

Science Daily - Wed, 24/09/2014 - 6:49pm
The millions of people who undergo major surgery each year have no way of knowing how long it will take them to recover from the operation. Some will feel better within days. For others, it will take a month or more. Right now, doctors can't tell patients which category they'll fit into. Now, researcher have discovered that the activity level of a small set of immune cells during the first 24 hours after surgery provides strong clues to how quickly patients will bounce back.

Seattle Passes Laws To Keep Residents From Wasting Food

Slashdot - Wed, 24/09/2014 - 6:42pm
schwit1 writes The new rules would allow garbage collectors to inspect trash cans and ticket offending parties if food and compostable material makes up 10 percent or more of the trash. The fines will begin at $1 for residents and $50 for businesses and apartment buildings. "SPU doesn’t expect to collect many fines, says Tim Croll, the agency’s solid-waste director. The city outlawed recyclable items from the trash nine years ago, but SPU has collected less than $2,000 in fines since then, Croll says. 'The point isn’t to raise revenue,' he said. 'We care more about reminding people to separate their materials.'"

Stanford Promises Not To Use Google Money For Privacy Research

Slashdot - Wed, 24/09/2014 - 5:57pm
An anonymous reader writes Stanford University has pledged not to use money from Google to fund privacy research at its Center for Internet and Society — a move that critics claim poses a threat to academic freedom. The center has long been generously funded by Google but its privacy research has proved damaging to the search giant as of late. Just two years ago, a researcher at the center helped uncover Google privacy violations that led to the company paying a record $22.5 million fine. In 2011-2012, the center's privacy director helped lead a project to create a "Do Not Track" standard. The effort, not supported by Google, would have made it harder for advertisers to track what people do online, and likely would have cut into Google's ad revenue. Both Stanford and Google say the change in funding was unrelated to the previous research.

Alzheimer's patients can still feel emotion long after memories have vanished

A new study further supports an inescapable message: caregivers have a profound influence -- good or bad -- on the emotional state of individuals with Alzheimer's disease. Patients may not remember a recent visit by a loved one or having been neglected by staff at a nursing home, but those actions can have a lasting impact on how they feel.

Diabetes researchers urge for new screening and management approach

Science Daily - Wed, 24/09/2014 - 5:46pm
Treating patients with prediabetes as if they had diabetes could help prevent or delay the most severe complications associated with this chronic disease, experts say. The researchers say that by not devising a treatment strategy for people with prediabetes, doctors run the risk of creating a pool of future patients with high blood sugar who then become more likely to develop serious complications, such as kidney disease, blindness, amputations, and heart disease.
