ANN ARBOR, Mich. -- Amphetamine and opioid use in pregnancy increased substantially over the last decade in the United States, a new Michigan Medicine-led study finds. And a disproportionate rise occurred in rural counties.

Among pregnant women in all parts of the country, amphetamine-affected births (mostly attributed to methamphetamine) doubled -- from 1.2 per 1,000 hospitalizations in 2008-2009 to 2.4 per 1,000 delivery hospitalizations by 2014-2015, the new research finds.

Up to 17 per cent of children could have symptoms consistent with fetal alcohol spectrum disorder (FASD) according to new research published today (Friday 30 November) in Preventive Medicine.

The UK has the fourth highest level of prenatal alcohol use in the world, but no estimates existed from a population-based study on how many people may have FASD. FASD is a group of lifelong conditions caused by exposure to alcohol in pregnancy that affect learning and behaviour and can cause physical abnormalities.

The Wizard of Oz, followed by Star Wars and Psycho, is identified as the most influential film of all time in a study published in the open access journal Applied Network Science.

Researchers at the University of Turin, Italy, calculated an influence score for 47,000 films listed in IMDb (the internet movie database). The score was based on how much each film had been referenced by subsequent films. The authors found that the top 20 most influential films were all produced before 1980 and mostly in the United States.

MADISON - A new, low-cost wound dressing developed by University of Wisconsin-Madison engineers could dramatically speed up healing in a surprising way.

The method leverages energy generated from a patient's own body motions to apply gentle electrical pulses at the site of an injury.

In rodent tests, the dressings reduced healing times to a mere three days compared to nearly two weeks for the normal healing process.

ANN ARBOR--By essentially turning down the pitch of sound waves, University of Michigan engineering researchers have devised a way to unlock greater amounts of data from acoustic fields than ever before.

That additional information could boost performance of passive sonar and echolocation systems for detecting and tracking adversaries in the ocean, medical imaging devices, seismic surveying systems for locating oil and mineral deposits, and possibly radar systems as well.

When tiny particles strike a metal surface at high speed -- for example, as coatings being sprayed or as micrometeorites pummeling a space station -- the moment of impact happens so fast that the details of process haven't been clearly understood, until now.

Capturing and reproducing realistic, real-world objects for any virtual environment is complex and time-consuming. Imagine using a conventional camera with a built-in flash--from any mobile device or off-the-shelf digital camera--to simplify this task. A global team of computer scientists have developed a novel method that replicates physical objects for the virtual and augmented reality space just using a point-and-shoot camera with a flash, without the need for additional, and oftentimes expensive, supporting hardware.

A North Carolina State University researcher has developed technology designed to allow cellular communication nodes in 5G systems to partition bandwidth more efficiently in order to improve end-to-end data transmission rates. In simulations, the tech is capable of meeting the international goal of 10 gigabits per second in peak performance areas.

Human skin contains sensitive nerve cells that detect pressure, temperature and other sensations that allow tactile interactions with the environment. To help robots and prosthetic devices attain these abilities, scientists are trying to develop electronic skins. Now researchers report a new method in ACS Applied Materials & Interfaces that creates an ultrathin, stretchable electronic skin, which could be used for a variety of human-machine interactions.

BINGHAMTON, N.Y. -- Can you deceive a deceiver? That's the question that computer scientists at Binghamton University, State University of New York have recently been exploring.

Assistant Professor of Computer Science Guanhua Yan and PhD student Zhan Shu are looking at how to make cyber deception a more effective tool against malicious hackers.
