Being responsible for providing their food straight from nature, the San tribes, also called Bushmen, have quickly found ways to evolve their hunting methods. It is assumed that it did not take long between the adoption of bowhunting and the application of poison arrow heads. An American team of researchers, led by Dr. Caroline S.

Parents who take the overparenting approach, known as helicopter parenting, are possibly hindering their child's development by becoming too heavily involved in homework.

A QUT study involving 866 parents from three Brisbane Catholic/independent schools found those who endorse overparenting beliefs tend to take more responsibility for their child doing their homework and also expect their child's teachers to take more responsibility for it.

PHOENIX -- Researchers from Mayo Clinic in Arizona and Banner Sun Health Research Institute have determined that testing a portion of a person's submandibular gland may be a way to diagnose early Parkinson's disease. The study was published this month in Movement Disorders, the official journal of the International Parkinson and Movement Disorders Society.

How do you find your food? Most animal species, whether they rummage through a refrigerator or stalk prey in the wild, obtain nutrients by consuming living organisms. Plants, for the most part, adopt a different feeding, or "trophic," strategy, making their own food through photosynthesis. There are, however, certain enterprising species that can do both: photosynthesize and consume prey. These organisms, found mostly in certain ocean plankton communities, live a flexible, "mixotrophic" lifestyle.

An interdisciplinary group of researchers at UC Santa Barbara has taken strides in the development of an underwater adhesive that has the potential for a variety of biomedical and non-biological applications.

Oklahoma City (February 1, 2016) When the audio on your television set or smart phone is too loud, you simply turn down the volume. What if we could do the same for the signaling in our bodies that essentially causes normal cells to turn cancerous?

New discoveries by researchers at the Stephenson Cancer Center at the University of Oklahoma may point to new ways to do just that.

Hiroshi Y. Yamada, Ph.D., and his team zeroed in on chromosome instability as a potential precursor to colon cancer.

Supposed "junk" DNA, found in between genes, plays a role in suppressing cancer, according to new research by Universities of Bath and Cambridge.

The human genome contains around three metres of DNA, of which only about two per cent contains genes that code for proteins. Since the sequencing of the complete human genome in 2000, scientists have puzzled over the role of the remaining 98 per cent.

CHARLOTTESVILLE, VA (FEBRUARY 2, 2016). In the paper "Stratification of risk to the surgical team in removal of small arms ammunition implanted in the craniofacial region: case report, by Jonathan A. Forbes, MD, and colleagues (published today in the Journal of Neurosurgery; http://thejns.org/doi/full/10.3171/2015.6.JNS15779), the authors discuss risk assessments that are necessary when a surgical team is required to remove embedded ordnance that may contain explosive materials.

Washington, D.C. - Monsanto's signature herbicide glyphosate, first marketed as "Roundup," is now the most widely and heavily applied weed-killer in the history of chemical agriculture in both the U.S. and globally, according to a landmark report published today in the journal, Environmental Sciences Europe.

BLOOMINGTON, Ind. -- The 2015 edition of the Carnegie Classification of Institutions of Higher Education is now available. Produced by an Indiana University research center, it is the most comprehensive review of institutional diversity at more than 4,660 colleges and universities in the United States.

Information about individual institutions and searchable data showing how they compare to their peers are available on a new website, carnegieclassifications.iu.edu. The full release of this information follows a month of public review.

Logging can encourage black rats to invade tropical rainforests by creating habitats they prefer, giving them the chance to displace native mammals.

Logging stresses animals living in tropical rainforests by disrupting and removing some of their habitat, but a new study shows that logging can cause further problems for the forests' inhabitants - by providing the perfect conditions for invasive species.

ANN ARBOR--Large national parks that are home to gorillas, chimpanzees and other great apes are focal points for much of the field research conducted in tropical Africa and Asia, resulting in crucial knowledge gaps and a biased view of broader conservation needs in those regions.

Those are key findings from a new study by University of Michigan anthropologist Andrew Marshall and several colleagues. They used Google Scholar to determine what effect the presence of great apes has on the amount and types of research done in protected areas in tropical Africa and Asia.

Cover your coughs in the Carolinas and don't double dip in Denver. A Tulane University study published in the American Journal of Health Economics found cities with teams in the Super Bowl see a rise in flu deaths.

Right after fertilization, embryos at the earliest stages of development tell their genes: "Forget what it was like in the sperm or egg where you came from."

When the process of epigenetic reprogramming is defective in mouse development, the consequences in adulthood can include abnormal repetitive behaviors, scientists have shown.

Their findings are published online in the journal eLife.

Scientists from the Icahn Institute for Genomics and Multiscale Biology at the Icahn School of Medicine at Mount Sinai, collaborating with NYU Langone Medical Center and a multi-center team of researchers, demonstrated for the first time that the microbiome of newborn babies delivered via cesarean section (C-section) can be partially restored to resemble that of vaginally delivered infants.
