A study by Newcastle University in Britain, indicates that green tea may protect the brain from diseases such as Alzheimer’s and other types of dementia. The research, published in the journal Phytomedicine, also suggests that the ancient Chinese remedy that has been popularized throughout the world may also have an important role in protecting the body against cancer.

In the study, scientists investigated whether the beneficial properties of green tea, which had already been proven in newly prepared and undigested tea, were still active once the tea was digested. (more…)

EAST LANSING, Mich. — Most college students in the United States do not grasp the scientific basis of the carbon cycle – an essential skill in understanding the causes and consequences of climate change, according to research published in the January issue of BioScience.

The study, whose authors include several current and former researchers from Michigan State University, calls for a new way of teaching – and, ultimately, comprehending – fundamental scientific principles such as the conservation of matter. (more…)

Children who receive antibiotics within the first six months of life are at a significantly increased risk of developing asthma and allergies by 6 years of age, even without a genetic predisposition, new research by the Yale School of Public Health suggests. The findings are reported online in the American Journal of Epidemiology. (more…)

Scientists Now Know Why Some Cancers Become Malignant and Others Don’t

Cancer cells reproduce by dividing in two, but a molecule known as PML limits how many times this can happen, according to researchers lead by Dr. Gerardo Ferbeyre of the University of Montreal’s Department of Biochemistry. The team proved that malignant cancers have problems with this molecule, meaning that in its absence they can continue to grow and eventually spread to other organs. Importantly, the presence of PML molecules can easily be detected, and could serve to diagnose whether a tumor is malignant or not. (more…)

*Collapse of Earth’s marine life 378 to 375 million years ago holds key*

An influx of invasive species can stop the dominant natural process of new species formation and trigger mass extinction events, according to research results published in the journal PLoS ONE.

The study of the collapse of Earth’s marine life 378 to 375 million years ago suggests that the planet’s current ecosystems, which are struggling with biodiversity loss, could meet a similar fate. (more…)

A research article presented by an Israeli team has unearthed new evidence on the history of the human being – namely that Homo sapiens may be far, far older than we imagined. A research team from the University of Tel Aviv has discovered fossilised teeth 400,000 years old. (more…)
