Study shows hope for early diagnosis of Alzheimer's

... study that team members conducted during the last three years, they determined early Alzheimer’s could be diagnosed with a high rate of accuracy evaluating electroencephalogram (EEG) signals. The study may lead to an earlier diagnosis, and therefore earlier treatment and improved quality of life, for peop...

Early-stage sperm cells created from human bone marrow

...perm in the laboratory and this should take around three to five years of experiments. I’ll be collaborating with other NESCI scientists to take this work forward. Prof Nayernia says a lengthy process of scientific investigation is required within a reasonable ethical and social framework to be able to ...

Manipulating nature: Scientists query wildlife birth-control method

...mental Sciences, questions immuno-contraception on three grounds. "Firstly, immuno-contraceptives are ineffective against substantial minorities of animals, probably for genetic reasons," Professor Cooper says. "If so, the genes responsible for this lack of response will be passed on to offspring. Withi...

New study sheds light on 'dark states' in DNA

Blame the brain for high blood pressure

...lammatory vascular disease of the brain. One in three people in the UK are likely to develop hypertension, and with 600 million people affected world wide, it is of pandemic proportions. The alarming statistic that nearly 60 per cent of patients remain hypertensive, even though they are taking drugs to ...

Biologists develop large gene dataset for rice plant

... representing nearly 47 million mRNA molecules and three million small RNAs, a larger dataset than has been reported for any other plant species. Small RNAs are considered one of most important discoveries in biotechnology in the last 10 years. Because they are so much smaller than mRNAs, small RNAs wen...

Iowa State University botanists identify new species of North American bamboo

...ic cousins. And we don't know how we ended up with three species in North America and 500 in East Asia," she said. Although botanists had previously studied the North American bamboos, no one had done extensive fieldwork to study and collect the plants in the wild, and questions remained as to whether t...

Tumor-suppressor gene is critical for placenta development

...by the E2f3 gene. Embryos missing both genes lived three days longer than the embryos missing Rb only, but all died before birth. "This showed that the interaction of these two proteins is definitely important," Leone says. "It strongly suggests that E2f3 is a key player in mediating Rb function in stem...

Scientists find new genes for Crohn's disease

...mparisons, the consortium identified variations in three genes ?PHOX2B, NCF4 and ATG16L1 ?as contributing significantly to the risk for Crohn's disease. According to corresponding author John D. Rioux, Ph.D., associate professor of medicine at the Montreal Heart Institute and at the Université de Mont...

The other surprising finding was just how innovative and plastic the different families were, even with these core residues, as one or another family had found ways to eliminate any but one of the 10 key residues. Using str...

Ebola outbreaks killing thousands of gorillas and chimpanzees

...ambridge University, and Stony Brook University at three sites in northern Republic of Congo, suggests that Ebola transmission between ape groups might occur through routes other than direct social encounter. For instance, as many as four different gorilla groups fed in the same fruit tree on a single day....

They react to the Earth’s external magnetic field in a very sensitive and specific manner, thus acting as a three-axis magnetometer. The study suggests that the birds sense the magnetic field in...

20-year study shows significant rise in childhood obesity, especially among girls

...h equal numbers of girls and boys from each of the three age groups ?four, ten and 16 - included in both samples. The data was drawn from official child health and school health records, as parents have a tendency to under-report the weight of obese children and are less likely to take part in studies. ...
