Corn waste potentially more than ethanol

...but to generate electricity directly. "People are looking at using cellulose to make ethanol," says Dr. Bruce E. Logan, the Kappe Professor of Environmental Engineering. "You can make ethanol from exploded corn stover, but once you have the sugars, you can make electricity directly." Logan's process uses ...

Septum keeps neurons in synch, can reduce epileptic seizures by 90 percent

The vicious cycle of rainforest destruction

...rs from the Leeds Earth and Biosphere Institute is looking at the impact of global warming on these sensitive areas. The researchers think we may be at the start of a vicious cycle, where global warming causes the rainforests to shrink, so increasing the amount of carbon in the atmosphere, raising the earth...

Patients and their doctors have different perceptions about HIV and its treatment

...patient-physician relationships, the importance of looking healthy, and other aspects related to HIV treatment. "While the surveys highlighted many similar views between physicians and patients on issues such as treatment goals and satisfaction with currently available antiretroviral drugs," said José M. ...

Friendly bacteria in chewing gum that bites back

...lus include the prevention of body odour. BASF are looking into producing a deodorant based on L. aladoris, which can inhibit odour-producing bacteria in the armpit. Similarly, tests have shown another strain, L. ala-odoris can reduce odour formation in feet. ...

How ancient whales lost their legs, got sleek and conquered the oceans

.... "But it's hard to say for certain because you're looking at events long after they occurred. As they suggest, there could have been a continual decrease in Sonic as the limbs reduced until the modern version of the animal arrived." The study itself, combining fossil and developmental data, is notable, Tab...

'Signature' of chromosome instability predicts cancer outcomes

...d thus the degree of chromosomal instability -- by looking for abnormal expression levels of genes at the different chromosomal locations. Next, the researchers identified 25 genes whose activity most strongly predicted chromosomal instability itself. This 25-gene signature was a significant predictor of ...

Chromosomal abnormalities in sperm higher after vasectomy reversal

...s themselves?" To date there have been no studies looking at these questions, he said, and his team are beginning the follow-up research. "We are collecting sperm during vasectomy reversal operations and will compare the aneuploidy rate of these and of the sperm we will collect each month in the future fr...

UF scientists restore sight to chickens with blinding disease

... that their child doesn't seem to be smiling at or looking at faces. Children may also poke or rub their eyes, behaviors clinically known as oculo-digital signs that may produce sensations of sight." Work remains to refine the viral delivery system that transfers the healthy genes to the photoreceptor cells...

How satellite tracking revealed the migratory mysteries of endangered Atlantic loggerhead turtles

...aid: "We were surprised to find such large turtles looking for food out in the open ocean, as it was previously thought that animals of this size would have moved back to forage in coastal zones. This means there are much greater numbers of the breeding population out at sea and far more that are vulnerable ...

Scientists aim to thwart use of flu as bioweapon

...ill have an immediate application among scientists looking for ways to stop or better treat "natural" flu. The work also helps scientists like John Treanor, M.D., and David Topham, Ph.D., who are designing and testing new vaccines designed to prevent all types of flu, including bird flu. The University is re...

Hopkins researchers develop new tool to watch real-time chemical activity in cells

...e chemicals could turn on or off the PKA enzyme by looking for green or blue glowing cells. Of the 160 chemicals tested, three caused cells to turn on the switch and two others caused cells to turn off the switch. The 160 chemicals tested are from the Johns Hopkins Clinical Compound Library, a collectio...

Long-term changes in experience cause neurons to sprout new long-lasting connections

...In this most recent experiment, Svoboda's team was looking to see if persistent changes in connectivity occurred after a long-term change in experience. They focused on the formation of new long-lasting spines that indicate robust connections between a neuron's highly branched dendrites and nearby axons. Den...

Despite acidity, orange juice could still be a source of foodborne disease

...etection methods. "Is it new, or were we just not looking for it 20 years ago? I think it is a little bit of both," says Beuchat. Beuchat notes that all outbreaks have been associated with unpasteurized orange juice. Anyone concerned should look for pasteurized orange juice. Most major grocery store b...

It's all in the genes

...s not been explored before. After all, the idea of looking at the genes of thousands of species in even a simple community is daunting at best. "What we've done is zero in on a foundation species, because not all species are as equally important ecologically," Whitham said. The foundation, or key, species ...

They were also hoping to find technologies that would effectively make biodiesel out of raw materials such as used restaurant oils and animal fats ?materials th...

Studies suggest new brain protein may help in treating schizophrenia, insomnia and anxiety

...se by the receiving neuron. Currently, the team is looking at whether natural mutations in the genes of NPS and its receptor might be associated with mental disorders and developing animal models that lack parts of the NPS system in order to better understand its functions. ...

For Stanford scientists, RNAi gene therapy takes two steps forward, one step back

...e or genes. As these concerns faded, things began looking up for RNAi with three RNAi therapies now in human trials - two for macular degeneration and one for a type of pneumonia. However, these studies involve simply infusing the RNAi molecules into the eye or lung. The RNAi effects in these therapies aren...

Study reveals how ADHD drugs work in brain

...ping addiction. "It is surprising that no one was looking at low-dose [ADHD] drugs because we know that the drugs are most effective only at low doses," says Berridge. "So we asked the natural question: what are these drugs doing at clinically relevant doses?" To answer that question, Berridge and his tea...
