The early human techno-tradition, known as Howiesons Poort, associated with Homo sapiens who lived in southern Africa about 66,000 to 59,000 years ago indicates that during this period of pronounced aridification they developed cultural innovations that allowed them to significantly enlarge the range of environments they occupied.

The simple act of silently talking to yourself in the third person during stressful times may help you control emotions without any additional mental effort than what you would use for first-person self-talk -- the way people normally talk to themselves.  

Many people select their shampoo based on smell. Unfortunately, that scent usually doesn't last long on hair. Now, one team reports a new way to help the fragrance 'stick' to hair longer.

A new study has investigated the impact of diet quality in mid-to-late-adulthood on visceral and liver fat not solely relying on Body Mass Index (BMI). Four different measures of diet quality were used to evaluate dietary intake of the multiethnic population over a twenty-year span. Maintaining a high quality diet during mid-to-late adulthood may prevent adverse metabolic consequences related to visceral adipose tissue (VAT) and non-alcoholic fatty liver (NAFL).

A researcher has discovered a way to convert dirty aluminium foil into a biofuel catalyst, which could help to solve global waste and energy problems.

Scientists are developing membranes for an efficient separation of gasses, to use for the production of oxygen or hydrogen, for example.

A recent discovery of a new magnetic semimetal could eventually lead to more energy-efficient computers, televisions, radios and other electronics.

A new era in international particle physics research officially began July 21 with a unique groundbreaking held a mile underground at the Sanford Underground Research Facility in South Dakota. Dignitaries, scientists and engineers from around the world marked the start of construction of a massive international experiment that could change our understanding of the universe. The Long-Baseline Neutrino Facility (LBNF) will house the international Deep Underground Neutrino Experiment (DUNE), which will be built and operated by roughly 1,000 scientists and engineers from 30 countries.

New research is challenging the age-old adage that money can't buy happiness. The study suggests that using money to buy free time -- such as paying to delegate household chores like cleaning and cooking -- is linked to greater life satisfaction.

Language patterns could be predicted by simple laws of physics, a new study has found. A theory using ideas from physics predicts where and how dialects occur.

Washington State University researchers have developed a way to grow algae more efficiently -- in days instead of weeks -- and make the algae more viable for several industries, including biofuels.

Earlier this year Arctic sea ice sank to a record low wintertime extent for the third straight year. Now NASA is flying a set of instruments north of Greenland to observe the impact of the melt season on the Arctic's oldest and thickest sea ice.

Engineers have invented a new kind of battery: one that is bio-compatible because it produces the same kind of ion-based electrical energy used by humans and other living things.

Using the largest and most informative molecular phylogenetic dataset ever analysed, evolutionary biologists were able to construct a new phylogenetic tree of jawed vertebrates. This new tree resolves several key relationships that have remained controversial, including the identification of lungfishes as the closest living relatives of land vertebrates. The evolution of jawed vertebrates is part of our own history since humans belong to the tetrapods more specifically we are mammals, or, even more specifically, primates.

Despite being relatively close together, two recently discovered hydrothermal vent fields in the Gulf of California host very different animal communities. This finding contradicts a common scientific assumption that neighboring vents will share similar animal communities, and suggests that local geology and vent-fluid chemistry are important factors affecting vent communities.
