No assembly required: Researchers automate microrobotic designs

Assembling a microrobot used to require a pair of needle-nosed tweezers, a microscope, steady hands and at least eight hours. But now University of Toronto Engineering researchers have developed a method that requires only a 3-D printer and 20 minutes.

Scientists planning now for asteroid flyby a decade away

On April 13, 2029, a speck of light will streak across the sky, getting brighter and faster. At one point it will travel more than the width of the full Moon within a minute and it will get as bright as the stars in the Little Dipper. But it won't be a satellite or an airplane—it will be a 1,100-foot-wide (340-meter-wide) near-Earth asteroid called 99942 Apophis that will cruise harmlessly by Earth, about 19,000 miles (31,000 kilometers) above the surface. That's within the distance that some of our spacecraft that orbit Earth.

Research suggests strategy for more equitable Medicare reimbursement

Those who were enrolled in both Medicare and Medicaid were sicker, had more cognitive impairments and difficulty functioning, and needed more social support than those who were not enrolled in both government programs, Saint Louis University research found. These patients also had significantly higher healthcare costs.

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.

Astronauts might soon grow SPACE tomatoes

Tiny tomato plants developed at the University of California, Riverside, could one day feed astronauts on the International Space Station. The plants have minimal leaves and stems but still produce a normal amount of fruit, making them a potentially productive crop for cultivation anywhere with limited soil and natural resources.

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.

Researchers use a novel approach to identify a transport protein in mycobacteria

A team headed by Dr. Claudia Jessen-Trefzer of the University of Freiburg's Institute for Pharmaceuticals Sciences has identified a transport protein in mycobacteria that is responsible for the uptake of the nutrient L-arabinofuranose. The lead authors of the study, Miaomiao Li of the Institute for Pharmaceuticals Sciences, Christoph Müller of the Institute for Biochemistry and Klemens Fröhlich of the Institute of Molecular Medicine and Cell Research at the University of Freiburg, used a novel approach that could simplify the identification of transport proteins in mycobacteria in the future. This class of proteins could play a key role in the development of new types of medications to tackle mycobacteria and treat diseases like tuberculosis in humans. The researchers' study is published in the journal Cell Chemical Biology.

Formation of honeycomb nanostructures finally explained

A few years ago, a promising new type of nanomaterial was observed experimentally, combining the virtues of semiconductors with those of graphene. The material is formed by nanocrystals that spontaneously assemble into a honeycomb structure. Until now, it was unclear why the nanocrystals show this specific behaviour, but Utrecht researchers Giuseppe Soligno and Daniel Vanmaekelbergh have now developed a simulation model that reproduces the formation of these nanostructures in detail. The researchers published their results in Physical Review X.

A personality test for ads: Machine learning algorithms could personalize advertisements for individual consumers

It's no surprise that images used for advertising on television and online play a powerful role in triggering emotions and shaping impressions of products or brands, but an ad that appeals to one person may seem irrelevant or distasteful to another. What if it was possible to start personalizing ads viewed by different consumers based on their personality types?

Study links gene to sleep problems in autism

Up to 80 percent of children with autism spectrum disorder (ASD) experience sleep problems. The source of these problems has been as much of a mystery as the exact causes of ASD, which scientists are still working to unravel. A new study led by a team of neuroscientists at Washington State University has brought scientists closer to identifying the causes of disturbed sleep in autism, which could open the door to future treatment that would bring relief to children with autism and their caregivers.

Single dose of targeted radiotherapy is safe and effective for prostate cancer

A single high dose of radiation that can be delivered directly to the tumour within a few minutes is a safe and effective technique for treating men with low risk prostate cancer, according to a study presented at the ESTRO 38 conference.

Children, their parents, and health professionals often underestimate children's higher weight status

More than half of parents underestimated their children's classification as overweight or obese—children themselves and health professionals also share this misperception, according to new research being presented at this year's European Congress on Obesity (ECO) in Glasgow, UK (28 April-1 May).

Heavier and taller children are more likely to develop kidney cancer as adults than their average-sized peers

A study of more than 300,000 individuals in Denmark, presented at this year's European Congress on Obesity in Glasgow, Scotland (28 April-1 May), reveals that heavier and taller children are at greater risk than their average-sized peers of developing renal cell carcinoma (RCC) as adults.
