African-American moms are helicopter parents too, but endgame is survival

African-American moms share many traits with helicopter parents, specifically when it comes to being overprotective and hypervigilant about their children's lives. But their goal is not only to get them into college. It's survival.

Privacy settings can help ease suspicion of recommendation-making sites and apps

When people see that they can control their privacy settings on websites and apps that offer entertainment or product recommendations, they tend to be more trusting of those sites, according to researchers.

Using a printed adversarial patch to fool an AI system

A trio of researchers at the University of KU Leuven in Belgium has found that it is possible to confuse an AI system by printing a certain picture and holding it against their body as the AI system tries to identify them as a human being. Simen Thys, Wiebe Van Ranst and Toon Goedemé have written a paper describing their efforts and have uploaded it to the arXiv preprint server. They have also posted a video on YouTube showing what they accomplished.

Plant cells eat their own... membranes and oil droplets

Biochemists at the U.S. Department of Energy's Brookhaven National Laboratory have discovered two ways that autophagy, or self-eating, controls the levels of oils in plant cells. The study, published in The Plant Cell on April 29, 2019, describes how this cannibalistic-sounding process actually helps plants survive. It also provides mechanistic details scientists might leverage to get plants to accumulate more oil.

Takes a licking and keeps on storing

Researchers at Washington University in St. Louis made an energy storage device that can withstand a hammer striking it more than 40 times. The shatterproof supercapacitor is also nonflammable, unlike lithium-ion batteries. The new work is the cover story of the April 23 issue of the journal Sustainable Energy and Fuels.

Climate, grasses and teeth—the evolution of South America mammals

Grass-eating mammals, including armadillos as big as Volkswagens, became more diverse in South America about 6 million years ago because shifts in atmospheric circulation drove changes in climate and vegetation, according to a University of Arizona-led research team.

New 3-D printed microscope promising for medical diagnostics in developing countries

Researchers have used 3-D printing to make an inexpensive and portable high-resolution microscope that is small and robust enough to use in the field or at the bedside. The high-resolution 3-D images provided by the instrument could potentially be used to detect diabetes, sickle cell disease, malaria and other diseases.

Improving security as artificial intelligence moves to smartphones

Smartphones, security cameras, and speakers are just a few of the devices that will soon be running more artificial intelligence software to speed up image- and speech-processing tasks. A compression technique known as quantization is smoothing the way by making deep learning models smaller to reduce computation and energy costs. But smaller models, it turns out, make it easier for malicious attackers to trick an AI system into misbehaving—a concern as more complex decision-making is handed off to machines.

A drug for autism? Potential treatment for Pitt-Hopkins syndrome offers clues

In 2019, geeks are cool, and the idea that they might be on the autism spectrum is celebrated. Nowhere is this truer than in Silicon Valley, one of the few places in America where social quirkiness and laser focus attention to detail are more often rewarded than criticized. Often lauded as an example of a success story in autism circles, renowned scientist Temple Grandin, once told a California newspaper, "Half of Silicon Valley's got mild autism, they just avoid the labels."

Strong evidence for the presence of umbrella branding effects in pharmaceutical markets

Umbrella branding is a practice that is common in markets for experience goods and consists in the marketing of otherwise unrelated products under the same brand name. In theory, umbrella branding allows firms to make better use of reputation to convince consumers that their products are of high quality.

Water creates traps in organic electronics

Poor-quality organic semiconductors can become high-quality semiconductors when manufactured in the correct way. Researchers at Linköping University show in an article in Nature Materials that the motion of charges in organic electronic devices is dramatically slowed down by minute amounts of water.

Fast, efficient and durable artificial synapse developed

The brain's capacity for simultaneously learning and memorizing large amounts of information while requiring little energy has inspired an entire field to pursue brain-like – or neuromorphic – computers. Researchers at Stanford University and Sandia National Laboratories previously developed one portion of such a computer: a device that acts as an artificial synapse, mimicking the way neurons communicate in the brain.

A first in medical robotics: Autonomous navigation inside the body

Bioengineers at Boston Children's Hospital report the first demonstration of a robot able to navigate autonomously inside the body. In an animal model of cardiac valve repair, the team programmed a robotic catheter to find its way along the walls of a beating, blood-filled heart to a leaky valve—without a surgeon's guidance. They report their work today in Science Robotics.

Squid skin inspires creation of next-generation space blanket

Drawing design inspiration from the skin of stealthy sea creatures, engineers at the University of California, Irvine have developed a next-generation, adaptive space blanket that gives users the ability to control their temperature. The innovation is detailed in a study published today in Nature Communications.

New device paves the way to 3-D-printed organs, food

More than 113,000 people are currently on the national transplant list. And with a shortage of donors, this means that about 20 people will die every day while waiting for an organ, according to the U.S. Department of Health.
