Left eye? Right eye? American robins have preference when looking at decoy eggs

Just as humans are usually left- or right-handed, other species sometimes prefer one appendage, or eye, over the other. A new study reveals that American robins that preferentially use one eye significantly more than the other when looking at their own clutch of eggs are also more likely to detect, and reject, a foreign egg placed in their nest by another bird species—or by a devious scientist.

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).

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.

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.

Medicare for All unlikely to cause surge in hospital use

As political leaders debate the merits of a future Medicare for All system in the U.S., some analysts predict that implementing universal coverage could cause a sharp, unaffordable increase in hospital use and costs, overwhelming the system. But new research by a team at Harvard Medical School and The City University of New York at Hunter College, published today in the Annals of Internal Medicine, contradicts that assumption, finding that past insurance expansions did not result in a net increase in hospital use. Instead, researchers found a redistribution of care, with increases in hospital care among those newly insured that was offset by small decreases among healthier and wealthier Americans.
