ASU researchers test antibacterial effects of healing clays

...y represent a new form of treatment, one that goes beyond the capacity of existing antibiotics. "And they could be produced and distributed cheaply," Williams notes. Humanitarians answer Internet challenge So how did a clay mineralogist whose background is in low temperature geochemistry become involv...

NASA snow data helps maintain nation's largest, oldest bison herd

... for food. In this search, some bison will migrate beyond the Park's borders. When bison are outside the boundaries of Yellowstone, the management authority on the northern boundaries of Yellowstone shifts to the State of Montana. Conflicts can arise between people who value conservation of the bison and th...

Trying to control pain can be a double-edged sword, say scientists

...the team went on to show that when faced with pain beyond their control, people who tend to feel more in control of their own lives show a lower response in the prefrontal cortex, indicating that they are less effective in coping with pain than those who don't expect to have control. "Patients with persi...

Cloned mice created from fully differentiated cells, a milestone in cloning research

...erentiated B cells, T cells and neurons had failed beyond the blastocyst stage. Only with a second step that involved combining the blastocyst with a fertilized embryo, which produces what biologists call a chimera, or by performing another nuclear transfer using the embryonic stem cells derived from these ...

Plant studies reveal how, where seeds store iron

... The findings reveal how essential it is to look beyond ferritin to understand how iron is stored by plants. The researchers say the stored iron in the vacuole is a key source of iron for developing seedlings. Seedlings that do not express the VIT1 protein grow poorly when iron is limited. In addition ...

Neuron cell stickiness may hold key to evolution of the human brain

...e been a key factor in why the human brain evolved beyond the brains of our primate relatives. In a study comparing the genomes of humans, chimpanzees, mice and other vertebrates, researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and Joint Genome Institute (...

Triple threat: World fin trade may harvest up to 73 million sharks per year

...grown over the past few years as demand has surged beyond sustainable levels for slow-to-produce shark populations and without regulation in most countries. Three shark species are listed on the Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES), and 20 percent are thre...

Underweight women at greater risk of miscarriage

...6 women whose most recent pregnancy had progressed beyond 12 weeks. The women were asked about socio-demographic, behavioural and other factors in their most recent pregnancy. The findings confirmed the findings of previous studies into possible risk factors, for example in relation to increased maternal ag...

Vaccination with embryonic stem cells prevents lung cancer in mice

...her the preventative effect of vaccination extends beyond our models of lung cancer (although in our state of Kentucky with its high smoking rates, lung cancer alone would be a big victory). We may also vaccinate ageing rodents, the majority of which develop endocrine tumours in old age. "In terms of hu...

And beyond helping to expand Wisconsin's booming biotechnology sector, success at ConjuGon will ultimately help nurture future scientific innovations from the university. "Because WARF is the licensor of my patent, and the company is a licensee, ConjGon, if s...

End of deforestation in view? Experts advance new way to size up global forest resources

... measuring forest cover. The novel approach looks beyond simply how much of a nation's area is covered by trees and considers the volume of timber, biomass, and captured carbon within the area. It produces an encouraging picture of Earth's forest situation and may change the way governments size up their ...

Replacing insulin is top-ranked breakthrough foreseen for health in developing world

...fects, disease, trauma and other causes. It moves beyond traditional transplant and replacement therapies to include the use of stem cells, soluble molecules, genetic engineering, tissue engineering, and advanced cell therapy. There is increasing research in regenerative medicine in both developed and dev...

Shrinking ponds signal warmer, dryer Alaska

...rwinter elsewhere, and this is something that goes beyond the refuges in Alaska," said A. David McGuire, co-author and professor of ecology at the Institute of Arctic Biology at UAF. National Wildlife Refuges cover more than 77 million acres in Alaska and make up 81% of the national refuge system. These r...

Edge density key to controlling gypsy moth spread

Without an Allee effect, these colonies would establish, but because gypsy moths exhibit an Allee effect, the low populations are...

Does natural selection drive the evolution of cancer?

...ells to self-destruct when their genes are mutated beyond repair. This protective cell-suicide program carried by normal cells is known as apoptosis. Seeing a tumor in this light opens a window on new therapeutic strategies. "It's not just a metaphor to say tumor cell populations are evolving," Maley ...

A natural chemical found in strawberries boosts memory in healthy mice

"It's clear that there is an extended sequence of steps which turn some genes on and others off, allowing a cell to become a liver cell, fo...
