Comment: Adult mammalian neurogenesis observed in the 40s? (Score 1) 59

by seminumerical (#43936161) Attached to: Atomic Bombs Help Solve Brain Mystery
My very elderly Canadian neighbour, at one time associated with Cold Spring Harbor Laboratory and retired from teaching at an American medical school more than 15 years ago, told me that a scientist at her university came up with photo micrographic evidence of of adult mammalian neurogenesis in the late 1940s. This caused some eye rolling and denial of tenure for heresy, and the fellow eventually disappeared. It had to wait 'til the sixties to be rediscovered by Altman.

Scientists Turn T-Shirts Into Body Armor 213

separsons writes "Scientists at the University of South Carolina recently transformed ordinary T-shirts into bulletproof armor. By splicing cotton with boron, the third hardest material on the planet, scientists created a shirt that was super elastic but also strong enough to deflect bullets. Xiaodong Li, lead researcher on the project, says the same tech may eventually be used to create lightweight, fuel-efficient cars and aircrafts."

+ - Scientists use brain scans to read minds ->

Submitted by nk497
nk497 (1345219) writes "University of California researchers have figured out how to read people's minds by looking at brain scans. Scientists could predict which of eight tasks a test subject was thinking about by looking at the scans correctly about 80 per cent of the time. But it's not Minority Report quite yet, Russell Poldrack, a professor of psychology at UCLA, said. "Our study suggests that the kinds of things that some people have talked about in terms of mind reading are probably still pretty far off," he said. "If we are only 80 per cent accurate with eight very different thoughts and we want to figure out what you're thinking out of millions of possible thoughts, we're still very far away from achieving that.""

jmwci1 writes "The U.S. Defense Department is enlisting an open source approach to software development — an about-face for such a historically top-down organization.

In recent weeks, the military has launched a collaborative platform called for its developers to share software, systems components and network services. The agency also signed an agreement with the Open Source Software Institute to allow 50 internally developed workforce management applications to be licensed to other government agencies, universities and companies."

Submitted by Trintech
Trintech (1137007) writes "Apple has reportedly placed orders for 100 million 8Gb NAND flash chips. (Note: The chips hold 8 Gigabits which equals 1 GigaByte) This is an odd move for Apple because they generally use much higher density chips even in small storage products like the 4GB iPod shuffle which uses a single 32Gb NAND chip. There has been some speculation as to what Apple might do with all these low density chips and, as usual, Apple refuses to comment.

1GB iPod Femto anyone?"

The 4 one minute sprints twice a week is not, that I know, of a recommended form of exercise. The researchers were interested in the minimum amount of exercise out of scientific curiosity.

As you can imagine they experimented with other schedules less than and greater than 4 min x 2 time per week. Blood sugar was under excellent control with the minimum stated.

Strength, flexibility, co-ordination, fat loss, etc. are other considerations: but they did demonstrate their hypothesis that you need to deplete energy from your muscles to make room to sop up glucose in the blood.

p.s., you can imagine the horror we will soon face on late night TV as an infomercial selling a cheap exercise bike promises you CONTROL DIABETES AND LOSE WEIGHT WITH 8 MINUTES EXERCISE A WEEK.

+ - Powerful Sonar Causes Deafness in Dolphins 1

Submitted by
Hugh Pickens
Hugh Pickens writes "Mass strandings could be caused because dolphins are rendered temporarily deaf by military sonar, experiments have shown. Tests on a captive dolphin have demonstrated that hearing can be lost for up to 40 minutes on exposure to sonar and may explain several strandings of dolphins and whales in the past decade. Most strandings are still thought to be natural events, but the tests strengthen fears that exercises by naval vessels equipped with sonar are responsible for at least some of them. For example, in the Bahamas in March 2000, 16 Cuvier's beaked whales and Blainville's beaked whales and a spotted dolphin beached during a US navy exercise in which sonar was used intensively for 16 hours (pdf). "The big question is what causes them to strand," says Dr. Aran Mooney, of the University of Hawaii. "What we are looking at are animals whose primary sense is hearing, like ours is seeing. Their ears are the most sensitive organ they have." In the experiment scientists fitted a harmless suction cup to the dolphin's head, with a sensor attached that monitored the animal's brainwaves and when the pings reached 203 decibels and were repeated, the neurological data showed the mammal had become deaf, for its brain no longer responded to sound. "We definitely showed that there are physiological and some behavioral effects [from repeated, loud sonar], but to extrapolate that into the wild, we don't really know," said Mooney."

+ - Chimpanzees exchange meat for sex->

Submitted by
the_therapist writes "A team from the Max Planck Institute for Evolutionary Anthropology in Germany, studied chimps in the Tai Forest reserve in Ivory Coast and discovered that chimpanzees enter into "deals" whereby they exchange meat for sex.

Among the findings are that "male chimps that are willing to share the proceeds of their hunting expeditions mate twice as often as their more selfish counterparts". They also found this to be "a long-term exchange, so males continue to share their catch with females when they are not fertile, copulating with them when they are"."

Yes. If you are addicted to caffeine, although a large amount of caffeine will keep you awake, a small amount can promote sleep.

Despite my claim to never drink tea or coffee after 4 p.m. I occasionally take a 1/4 cup of tea before bed if I need to get to sleep quickly because I'll be rising early.

This is in proportion to how much tea/coffee I drink during the day: 2 or rarely 3 cups. I've known 6 cup a day coffee drinkers to drink an entire cup of coffee before bed. (I've also known them to have anxiety, shaky hands, and logorrhea)


+ - Microsoft Sued for $558 Million Over Uniloc Patent->

Submitted by eldavojohn
eldavojohn (898314) writes "Microsoft has been served papers claiming their state of the art product activation system infringes on a Singapore based company named Uniloc's patent. Bloomberg is reporting that a lawyer for Uniloc asked a federal court for $558 million in royalties from Microsoft. The official court order is here in PDF. This concerns the activation system of Windows XP operating system and some Office programs--Uniloc has decided that royalties of $2.50 for each of the 223 million activations is a fair price for Microsoft to pay. The patent ax swings both ways. The two seem to have a long history of court action."
