Finding one's way in the rainforest

Knowing which direction to go in order to reach food or home is important for many animal species, including humans. For human foragers who travel long distances every day for hunting and gathering, orientation skills are essential. Haneul Jang and her colleagues from the Max Planck Institute for Evolutionary Anthropology set out to study how the Mbendjele BaYaka people in Republic of the Congo orient themselves in the dense rainforest. The researchers conducted more than 600 pointing tests with 54 Mbendjele BaYaka men, women and children aged between six and 76 years, in which the participants were asked to point to an out-of-sight target in more than 60 different rainforest locations (including the camp).

Microfluidics device helps diagnose sepsis in minutes

A novel sensor designed by MIT researchers could dramatically accelerate the process of diagnosing sepsis, a leading cause of death in U.S. hospitals that kills nearly 250,000 patients annually.

How stimulant treatment prevents serious outcomes of ADHD

An analysis of three previous studies of children and young adults with attention-deficit hyperactivity disorder (ADHD) quantifies for the first time the extent to which stimulant treatment reduces the development of mood disorders, school problems, conduct disorders, substance use disorders and other problems. The study led by Massachusetts General Hospital investigators is being published online in the Journal of Adolescent Health.

Rise of Candida auris blamed on global warming

Global warming may have played a pivotal role in the emergence of Candida auris, according to a new study published in mBio, an open-access journal of the American Society for Microbiology. C. auris, which is often multi-drug resistant and is a serious public health threat, may be the first example of a new fungal disease emerging from climate change.

The properties of composites for constructing reliable trains

Composite materials are increasingly popular. One of the primary composite materials for modern structures is glass fiber reinforced plastic (GFRP), which is commonly used in aviation, modern transport and wind power plants. Scientists of South Ural State University have carried out extensive studies of ballistic properties of GFRP to improve the efficiency of its use.

How did Africa's grasslands get started?

Between 10 million and 6 million years ago, vegetation across much of the world underwent a transformation, as warmth-adapted grasses displaced previously dominant plants, shrubs and trees. The new grasses carried out the chemical reactions required for photosynthesis in a distinct new way. Scientists have labeled this new process the C4 pathway. In East Africa, the changeover coincided with the evolution of mammal lineages that we recognize today, including early human ancestors. Today, C4 plants comprise about one-quarter of the Earth's vegetation, from the Great Plains of North America to western China, Australia and much of sub-Saharan Africa.

Hands-on dads more prone to jealousy in the face of infidelity

A new international study has found fathers who invest time and money in their children are likely to be more jealous when their partner cheats on them compared with dads who are less involved.

Adolescents who skip breakfast may develop obesity

A paper published in Scientific Reports describes how researchers affiliated with the University of São Paulo's Medical School (FM-USP) in Brazil and colleagues at institutions in Europe evaluated behaviors leading to weight gain in adolescents. Childhood obesity can favor the premature emergence of health issues such as type 2 diabetes and cardiovascular disease.

Rejected and unfilled prescriptions for new, more expensive cholesterol drugs tied to higher heart, stroke risk

Patients appear to be at higher risk of heart problems or stroke when prescriptions for the newest cholesterol-lowering drugs are rejected by insurance companies or unfilled by patients, according to new research in Circulation: Cardiovascular Quality and Outcomes, an American Heart Association journal.

North Carolina coastal flooding is worsening with climate change, population growth

A historic 120-year-old data set is allowing researchers to confirm what data modeling systems have been predicting about climate change: Climate change is increasing precipitation events like hurricanes, tropical storms and floods.

Spontaneous magnetization in a non-magnetic interacting metal

Over the past decade, numerous physics studies have explored how oscillating electric fields produced by lasers or microwave sources can be used to dynamically alter the properties of materials on demand. In a new study featured in Nature Physics, two researchers at the University of Copenhagen and Nanyang Technological University (NTU), in Singapore, have built upon the findings of these studies, uncovering a mechanism through which a non-magnetic interacting metal can spontaneously magnetize.

Scientists discover new chemistry that may help explain the origins of cellular life

Before life began on Earth, the environment likely contained a massive number of chemicals that reacted with each other more or less randomly, and it is unclear how the complexity of cells could have emerged from such chemical chaos. Now, a team led by Tony Z. Jia at the Tokyo Institute of Technology and Kuhan Chandru of the National University of Malaysia has shown that simple α-hydroxy acids, like glycolic and lactic acid, spontaneously polymerize and self-assemble into polyester microdroplets when dried at moderate temperatures followed by rehydration. This could be what happened along primitive beaches and river banks, or in drying puddles. These form a new type of cell-like compartment that can trap and concentrate biomolecules like nucleic acids and proteins. These droplets, unlike most modern cells, are able to merge and reform easily, and thus could have hosted versatile early genetic and metabolic systems potentially critical for the origins of life.
