UBC researchers find new superbug weapon for near-empty antibiotics arsenal

...ock co-founded Inimex, which conducted many of the experiments required for the study. Researchers expect it will be about 12-15 months before the discovery is introduced into human clinical trials. ...

Meat and two neutrons -- the key to a longer life

...erse side effects. If this is borne out by further experiments the implications are profound.' Isotopes could also be used in pet food or as a means to protect workers or soldiers from radiation. Deuterium, a natural isotope of heavy hydrogen, having one proton and on neutron,whereas normal hydrogen has one pr...

Viral protein is an effective preventative against infection

...rmal flora untouched. "We knew from our previous experiments that if you treat an animal infected or colonized with pneumococci or streptococci with these lysins, you could cure or decolonize them," says Fischetti. "But I was looking for a way to see if lysins would work for secondary infections too, and John ...

Jefferson scientists uncover gene mutation that cuts colon polyps, may suppress cancer

... turn, potentially cut the risk of cancer. In experiments with mice genetically prone to develop polyps, researchers discovered that animals carrying one copy of the damaged gene, Atp5a1, had about 90 percent fewer polyps in the small intestine and colon. Because people with large numbers of such polyps are...

Termites get the vibe on what tastes good

... most wood." The researchers are designing further experiments to test termites' assessment methods in an attempt to determine precisely what aspect of the vibrations termites are responding to in assessing food. "If we understand how they use vibrations to assess their food, we might be able to exploit this to ...

Trojan horse strategy defeats drug-resistant bacteria

...microbial approach can kill bacteria in laboratory experiments and eliminate life-threatening infections in mice by interfering with a key bacterial nutrient, according to research led by a University of Washington scientist. The joint project, conducted at the UW, the University of Iowa, and the University of C...

Neighbors gone, fruits gone, species gone

...nts and animals are hard to predict. We need field experiments such as this one to understand the potentially disastrous effects," says Christine Mller. "There has been a long tradition of studying direct interactions in pollination biology," says Dennis Hansen, "but only little focus on indirect interactions, e...

Study: Chest compressions without mouth-to-mouth better for out-of-hospital cardiac arrest

...eport confirms that what we have learned in animal experiments applies to humans as well," says Gordon A. Ewy, MD, director of the Sarver Heart Center at The University of Arizona in Tucson where chest-compression-only resuscitation was developed. "Bystander-initiated continuous chest compressions without mouth-...

Erectile dysfunction in diabetes is due to selective defect in the brain

...ive STZ (vehicle injected) served as controls. The experiments began on each of the rats four weeks after the injections. Four experiments were conducted. Experiment one examined the effect of L-NMMA on NMDA mediated behavioral responses i...

Making memories that last a lifetime

... of mental retardation, Miller and Sweatt designed experiments to test whether methylation specifically regulates memory formation. In their experiments, the researchers conditioned fearful memories in rats by giving the animals mild shocks when they were in a specific training chamber. The researchers could t...

Gene therapy for blindness clears hurdle in mice

...he gene drastically muzzled, scientists have begun experiments to create a therapy in which healthy versions of the gene can be introduced into the eye using an apparently harmless virus to deliver the genetic material. "If we reduce the amount of protein formed by mutated rhodopsin, that may be sufficient to ...

Health care system for aging nerve cells

Their study reveals that added CO2 has a so-called "primingeffect," stimulating certain microbes and increasing decompositi...

Anti-fungal drug kills TB bug

Social tolerance allows bonobos to outperform chimpanzees on a cooperative task

In experiments designed to deepen our understanding of how cooperative behavior evolves, researchers have found that bonobos, a particularly sociable relative of the chimpanzee, are more successful than chimpanzees at cooperating to retrieve food, even though chimp...

Plants' management of nutrient suggests environmental remedies

...he journal Nature. Arabidopsis is favored for such experiments because it has a relatively short life cycle of eight weeks and its genome has been completely sequenced. By tracking the glow of the jellyfish molecules, the researchers learned that CAS plays a number of roles in plants. The scientists initially ...

'Guardian of the genome' protein found to underlie skin tanning

...ing alpha-MSH was 30 times above normal. Further experiments clinched the case for p53's role in tanning. When researchers inserted p53 into keratinocytes, POMC levels rose dramatically. When they delivered UV radiation to mice whose keratinocytes lacked p53, POMC production was not induced and the mice did no...
