Honeydew honeys are better antioxidants than nectar honeys

...ctrical conductivity. “These laboratory results show some aspects that people could use to get an idea about which honeys are likely to have the most potent antioxidant properties,?says Pérez....

Too much of a good thing? Excess nutrients or water limit biodiversity

... Both supported their hypothesis. "Our results show that the loss of plant species from a habitat due to nutrient pollution can persist for more than 100 years," Harpole said. "Thus human actions that simplify habitats can lead to long-term loss of biodiversity."...

Thinking with the spinal cord?

...ons, during network activity underlying movements, show the similar irregular firing patterns as seen in the cerebral cortex. New approach "Our findings contradict conventional wisdom about spinal cord functions," says Rune W. Berg from Department of Neuroscience and Pharmacology at the Faculty of...

Scientists identify specific enzymes that make meningitis hard to fight

...repairing different types of DNA damage, were able show the pathogen can 'fend off' different types of DNA damage while in the bloodstream. In theory, finding some way of disabling these enzymes would render the bacteria unable to repair itself, and therefore vulnerable to attack and defeat by the body's ...

E. coli bacteria migrating between humans, chimps in Ugandan park

...tor of the study. The new findings, Goldberg said, show that over-the-counter sales of antibiotics for human consumption can also have an impact on wildlife. The research team, which included researchers from Makerere University in Kampala, Uganda, and McGill University in Montreal, examined two o...

Magnetic system could be key to surgery without scars

... formulated after Dr. Cadeddu watched a television show featuring teens who used magnets to hold studs on their lips to avoid getting their lips pierced. “Once you think about, it’s an obvious thing,?said Dr. Cadeddu, whose team of urologists and surgeons worked with engineers from UTA’s Automation and...

How stem cells are regulated

...t of specific cancer types. BRIC’s new results show that a different subgroup of Jumonji proteins is essential for cellular differentiation. The Jumonji enzymes can turn off, or inactivate, particular genes that play an important part in embryogenesis. The conclusions are based on studies of the nemat...

A revolution in the monitoring of unborn babies

...risk babies a year in the UK alone. Statistics show that as many as 10 babies a day are stillborn in the UK and 10 per cent of all pregnancies each year are high risk. The monitor lets doctors read signals produced naturally by the unborn baby’s heart. They can then intervene if necessary and potentia...

Plastic that degrades in seawater could be boon for cruise industry and others

... baby’s health outcome. This study is the first to show that the baby benefited from the therapy, especially those who are born very prematurely (at 24 to 28 weeks). Using a composite measure of the newborn’s health including perinatal death, markers of brain damage and serious lung and bowel complication...

Improving outcomes in premature births

... baby’s health outcome. This study is the first to show that the baby benefited from the therapy, especially those who are born very prematurely (at 24 to 28 weeks). Using a composite measure of the newborn’s health including perinatal death, markers of brain damage and serious lung and bowel complication...

Fish can determine their social rank by observation alone, study finds

...her on the dominance hierarchy. "These results show that fish do, in fact, use transitive inference to figure out where they rank in the social order," Fernald said. "I was amazed that they could do this through vicarious experience, just by watching other males fight. In Lake Tanganyika, where condit...

Fish growth changes enhanced by climate change

...e examination of fish earbones, or otoliths, which show similar characteristics to the growth rings used to date the age of trees. The work was done in collaboration with the Victorian Marine and Aquatic Fisheries Research Institute, which has specialist skills in analysing otoliths. Water temperature...

Turning a cellular sentinel into a cancer killer

...fferent types of cancer. The researchers' findings show for the first time that inactivating the p53 gene is necessary for maintaining tumors. While the researchers caution that cancers can mutate to circumvent p53 reactivation, they believe their findings offer ideas for new approaches to cancer therapy....

Manual dishwashing study digs up dirt on dish cleanliness

... higher-temperature alternatives. "We wanted to show that employees could use a more comfortable washing technique and still get clean dishes," Pascall said. "We were able to do that, and we did it by using different combinations of washing, rinsing, and sanitizing." But all dishes are not created e...

Anti-fungal drug stops blood vessel growth

...wer inhibitory effect. “Our screening test did show that cholesterol-lowering statins also appear to stop blood vessel growth,?Liu says, “so there is likely some important connection between cholesterol and angiogenesis.? While the researchers still must tease out exactly how itraconazole works to ...

Bacterial response to oxidation studied as toxin barometer

...ert reaction to toxins that cause oxidative stress show promise as a biosensor to predict public health threats. At the 233rd American Chemical Society national meeting in Chicago March 25-29, researchers from Virginia Tech and the Edward Via Virginia College of Osteopathic Medicine (VCOM) will report th...

The influence of the menstrual cycle on the female brain

...and affective functions. These two observations show that gonadal neurosteroids6 modulate the female dopaminergic system, but the question remains as to whether these hormones modulate the reward system neuron network. In order to answer this question, the team developed an experiment using functiona...

How fish conquered the ocean

...pares the egg for spawning and fertilization. They show that teleost vitellogenins have undergone a post-R3 lineage-specific gene duplication to form paralogous clusters that correlate to the pelagic and benthic character of the eggs. The alteration in the function (neo-functionalization) of one of the du...

Common parasitic infection leads to increased risk for HIV infection

...though studies have been undertaken in the past to show the link between sexually transmitted infections and susceptibility to HIV, the study published in the March 1 issue of The Journal of Infectious Diseases, now available online, is one of the first to demonstrate a statistically significant associati...

Swimming 'to the left' gets bacteria upstream, and may promote infection

...selves in this manner. Köser and his colleagues show that this phenomenon allows flagellated bacteria, such as E. coli, to find crevices or imperfections on the surface, get trapped, and swim upstream. This allows the bacteria to eventually locate large reservoirs with richer sources of food and better...
