Atomic-scale manufacturing now a reality  

Scientists have applied a machine learning technique using artificial intelligence to perfect and automate atomic-scale manufacturing, something which has never been done before. The vastly greener, faster, smaller technology enabled by this development greatly reduces impact on the climate while still satisfying the insatiable demands of the information age.

Chimpanzee calls differ according to context  

An important question in the evolution of language is what caused animal calls to diversify and to encode different information. A team of scientists has found that chimpanzees use the quiet 'hoo' call in three different behavioral contexts -- alert, travel and rest. The need to stay together in low visibility habitat may have facilitated the evolution of call subtypes.

Debunking the Biggest Myths About 'Technology Addiction'  

How concerned should people be about the psychological effects of screen time? Balancing technology use with other aspects of daily life seems reasonable, but there is a lot of conflicting advice about where that balance should be. Much of the discussion is framed around fighting "addiction" to technology. But to me, that resembles a moral panic, giving voice to scary claims based on weak data. For example, in April 2018, television journalist Katie Couric's "America Inside Out"...

Here we have developed a non-plasma high-speed anisotropic etching process using a thermochemical reaction between nickel and diamond in high-temperature water vapor. This technology is expected to contribute to fabrication of diamond devices of excellent performance with highly reduced

Research supports restrictions on opioid-containing cold medicines for children  

Prescription cough and cold medicines containing the opioid hydrocodone were more likely to cause serious side effects in children than those containing codeine, according to a new study. The research supports recent U.S. Food and Drug Administration (FDA) restrictions on prescription hydrocodone- and codeine-containing cough medicines for children and suggests that opioids in general should not be prescribed for coughs and colds in pediatric populations.

The price of chaos: A new model virtually pits new investors against experienced ones  

Variation in expertise and risk-taking behaviors among investors regularly sends markets on roller-coaster rides. Researchers now describe the intricate dynamics driving a financial markets model. Their model takes aim to simulate asset pricing when mixed groups of investors enter a market. By examining bifurcation conditions, they described transitions between different chaotic dynamical regimes. They showed that their model can reflect the nature of real markets by switching between bear and b

Heart surgery: To have or not to have...your left atrial appendage closed  

Each year in the US, more than 300,000 people have heart surgery. To reduce risk of stroke for their patients, surgeons often will close the left atrial appendage, which is a small sac in the left side of the heart where many blood clots form, during these surgeries. Adding this procedure is likely the right choice for certain patients but not all.

Building a brain, cell by cell: Researchers make a mini neuron network (of two)  

Neurological research uses simplified models consisting of artificial collections of neurons. These models are often imprecise, because it is difficult to control how neurons connect to one another. Researchers have developed a technique that uses microscopic plates to guide how individual neurons grow, and showed that they can make functional connections between specific neurons. The findings may aid in the development of more precise models of neuron networks.
