Intestinal bacteria influence food transit through the gut

Food transit through the small intestine affects the body’s absorption of nutrients and, consequently, our health. The discovery that food transit time is regulated by a hormone indicates new ways to increase the intestinal absorption of nutrients, and thus potentially treat malnutrition. One of the tasks of the gut microbiota is to break down essential… Read More »

U.S. wildlife agency destroys 6 tons of contraband ivory

The U.S. Fish and Wildlife Service pulverized about 6 tons of confiscated elephant ivory Thursday in an effort to strip the items of their value and make a statement against poaching. Photographs taken before the event show ivory boxes, intricately carved statues and staffs, masks and countless pieces of jewelry, all stuffed into crates ready… Read More »

Scientists isolate new human pluripotent stem cells

One of the obstacles to employing human embryonic stem cells for medical use lies in their very promise: They are born to rapidly differentiate into other cell types. Until now, scientists have not been able to efficiently keep embryonic stem cells in their pristine stem state. The alternative that has been proposed to embryonic stem… Read More »

Test identifies seven distinct types of breast cancer

… Scientists funded by the Breast Cancer Campaign looked for signature biomarkers in 1,073 tumour samples from the charity’s tissue bank. They found that 93 per cent of the samples fitted perfectly into one of seven classes while another seven per cent had mixed characteristics and were harder to categorise. Further verification of the seven… Read More »

Chemists show precursors of life self assemble godlessly

How life came about from inanimate sets of chemicals is still a mystery. While we may never be certain which chemicals existed on prebiotic Earth, we can study the biomolecules we have today to give us clues about what happened three billion years ago. Now scientists have used a set of these biomolecules to show… Read More »

A New Map of How We Think: Top Brain/Bottom Brain

… research reveals that the top-brain system uses information about the surrounding environment (in combination with other sorts of information, such as emotional reactions and the need for food or drink) to figure out which goals to try to achieve. It actively formulates plans, generates expectations about what should happen when a plan is executed… Read More »

Brains cleaned while you sleep

It’s no secret that too little shut-eye can drain your brain, but scientists haven’t fully understood why. Now, a new study suggests that a good night’s sleep leaves you feeling sharp and refreshed because a newly discovered system that scrubs away neural waste is mostly active when you’re at rest. It’s a revelation that could… Read More »

Wonder drug and supercharged immune cells offer cancer hope

GENETICALLY “supercharging” immune cells, and combining this with a new wonder drug, offers a new way to boost the body’s cancer defences, Melbourne researchers have found. Peter MacCallum Cancer Centre researchers hope the new treatment combination, tested successfully in animals, will eventually allow cancer patients to be immunised against relapses. The team combined the anti-PD-1… Read More »

Why glial cells should be included in the BRAIN initative

Glia, the non-neuronal cells that make up most of the brain, must not be left out of the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative, says R. Douglas Fields, chief of the Nervous System Development and Plasticity Section at NIH, in Nature News. “A major stumbling block is the project’s failure to consider that… Read More »

Why Do Mysterious Lizards Have Green Blood?

It’s not a trick of the imagination or a penchant for food coloring –Prasinohaema skinks living on the island of New Guinea actually have green blood, bones, and tissue – and one scientist is trying to figure out why. Louisiana State University biologist and National Geographic explorer Christopher Austin first became interested in these odd… Read More »

Scientists Turn Hunger On and Off In Brain

Recently, scientists have been coming up with more and more, er, creative ways of combatting the potentially fatal effects of obesity. Soon though, people with overeating disorders might have a single solution that stops the problem at the root. We could just turn off part of their brain. In pioneering research, a team of scientists… Read More »

Link between gluten and Alzheimer’s

Dr. Mercola writes: Alzheimer’s disease is at epidemic proportions, with 5.4 million Americans—including one in eight people aged 65 and over—living with the disease. In the next 20 years, it is projected that Alzheimer’s will affect one in four Americans, rivaling the current prevalence of obesity and diabetes. There is still no known accepted cure… Read More »

Unusual mechanism of DNA synthesis could explain genetic mutations

… When chromosomes experience double-strand breaks due to oxidation,ionizing radiation, replication errors and certain metabolic products, cells utilize their genetically similar chromosomes to patch the gaps via a mechanism that involves both ends of the broken molecules. To repair a broken chromosome that lost one end, a unique configuration of the DNAreplication machinery is deployed… Read More »
