Brightening prospects of using fluorescent nanotubes in medical applications

...ot is insoluble in water. So researchers routinely mix it with special soap and give it a dose of ultrasound to break apart clumps of nanotubes and force them to dissolve. The result is a dark liquid that is routinely put into an ultracentrifuge that subjects them to forces a few thousand times that of g...

Study finds mix of disease processes at work in brains of most people with dementia

...and cerebral infarcts (strokes) is the most common mix of pathologies in the brains of people with dementia. The implication of these findings is that public health efforts to prevent and treat vascular disease could potentially reduce the occurrence of dementia, the researchers say in the paper. The ...

Ice Age extinction claimed highly carnivorous Alaskan wolves

...sk ox and caribou—suggesting that their diet was a mix of these large species. The cause of Pleistocene extinction (called the “megafaunal” extinction because of the large size of many of its victims) is controversial. It has been variously blamed on human hunting or climate change, or on a combina...

Helium helps patients breathe easier

...of exertion. The best results were achieved with a mix of 40 per cent oxygen and 60 per cent helium. The helium-hyperoxia mixture improved the exercise tolerance of the patients by 245 per cent compared with air (21 per cent oxygen, 79 per cent nitrogen), by 56 per cent compared with hyperoxia (40 per...

This is surprising behavior for these arachnids long-thought to be purely aggressive and anti-social, according to a Cornell researcher. Social behavior is extremely rare in arachnids, a class that includes spiders, amblypygids, s...

UW launches study testing adult stem cells for heart damage repair

Mitochondrial genes move to the nucleus -- but it's not for the sex

...rast, the components are further separated if they mix and match haphazardly during out-crossing. Brandvain said the finding contradicts the expectation that mitochondrial genes migrate to the nucleus because of the evolutionary benefits conferred by sexual recombination. "The benefits of sex could h...

Lower carbon dioxide emissions from coal-fueled power plants possible with technology development

...scale plants,?said Rochelle. “With the current mix of new power plants, by the year 2030,?he said, “about two-thirds of all carbon dioxide emissions will come from existing coal-fueled power plants, so it is critical that we demonstrate technology to address these releases.?

In presence of fragrant cleaning products, air purifiers that emit ozone can dirty the air

...iddle of the room along with a large fan to better mix the air. At timed intervals, limonene vapor was injected in the room. Samples of the air were taken about one meter from the purifier and analyzed for ozone and particulate matter levels. The researchers tested two types of air purifiers ?a commer...

Microbes compete with animals for food by making it stink

...ait's chemistry," Hay said. "It's either a complex mix of chemicals or perhaps something we destroyed during our lab test processes or maybe a chemical present in a very small amount that we failed to identify. There's uncertainty about this." What's certain is that microbes are an omnipresent part of...

U of M researchers invent 'flashy' new process to turn soy oil, glucose into hydrogen

... "It happens here because we vaporize the fuel and mix it with oxygen before it sees the catalyst so it doesn't burn to char. This is potentially 100 times faster than what is currently available to make syngas and hydrogen." Schmidt gained national attention in February 2004, when a team he headed in...

Cracking the egg

New dyslexia theory blames 'noise'

...a. Many still think that to have dyslexia means to mix up your letters (one of many possible symptoms having to do with word recognition, directional ability and decoding of symbols). What is known is that dyslexia affects millions of children, with estimates of its incidence ranging from 5 to 15 per...
