Immediate, science-based community action can stop insect decline

This year, German environmentalists collected 1.75 million signatures for a 'save the bees' law requiring an immediate transition toward organic farming. But to create healthy ecosystems worldwide, people in communities across the globe will need to take similar action based on empathy for insects—and not only for bees and butterflies—according to entomologists Yves Basset from the Smith-sonian Tropical Research Institute and Greg Lamarre from the University of South Bohemia, writing in Science. The authors present immediate, science-based actions to mitigate insect decline.

Researchers create multi-junction solar cells from off-the-shelf components

Multi-junction solar cells are both the most efficient type of solar cell on the market today and the most expensive type of solar cell to produce. In a proof-of-concept paper, researchers from North Carolina State University detail a new approach for creating multi-junction solar cells using off-the-shelf components, resulting in lower cost, high-efficiency solar cells for use in multiple applications.

The RoboBee flies solo—Cutting the power cord for the first untethered flight

The RoboBee—the insect-inspired microrobot developed by researchers at Harvard University—has become the lightest vehicle ever to achieve sustained flight without the assistance of a power cord. After decades of work, the researchers achieved untethered flight by making several important changes to the RoboBee, including the addition of a second pair of wings. That change, along with less visible changes to the actuators and transmission ratio, gave the RoboBee enough lift for the researchers to attach solar cells and an electronics panel.

A snapshot in time: Study captures fleeting cell differences that can alter disease risk

In cinema and science fiction, one small change in the past can have major, sometimes life-changing effects in the future. Using a series of snapshots, researchers recently captured such so-called "butterfly effects" in heart muscle cell development, and say this new view into the sequence of gene expression activity may lead to better understanding disease risk.

Enhancing the vertical mobility of six-legged robot RHex using microspines

A team of researchers at Carnagie Mellon University has recently proposed a method to improve the vertical mobility of a renowned hexapod robot. Their approach, presented in a paper pre-published on arXiv, entails the addition of microspines to RHex, an existing cockroach-inspired robotic platform designed to navigate unstructured environments at relatively high speed.

Solar energy could turn the Belt and Road Initiative green

The region covered by the Belt and Road Initiative (BRI) has significant potential to be powered by solar energy, researchers report June 27 in the journal Joule. Less than 4 percent of the maximum solar potential of the region could meet the BRI's electricity demand for 2030. The research suggests a possible solution to reduce BRI countries' need for fossil fuels as they develop. This is the first time the renewable energy potential of the region is quantified.

Reducing delays in identifying visceral leishmaniasis

Women in Indian states with endemic visceral leishmaniasis—also known as Kala Azar—should be encouraged to seek care for persistent fever without delay. Raised awareness about the disease and its symptoms, and the prioritization of women's care-seeking over household work could help reduce fatalities and potentially reduce overall transmission, according to research by independent consultant Beulah Jayakumar and colleagues, published in PLOS Neglected Tropical Diseases.

Drag-and-drop data analytics

In the Iron Man movies, Tony Stark uses a holographic computer to project 3-D data into thin air, manipulate them with his hands, and find fixes to his superhero troubles. In the same vein, researchers from MIT and Brown University have now developed a system for interactive data analytics that runs on touchscreens and lets everyone—not just genius, billionaire, playboy philanthropists—tackle real-world issues.

Too many antioxidants may cause lung cancer spread

A new study explains why lung cancer spreads faster in patients with certain genetic changes, and suggests that taking vitamin E, long thought of as preventive, may cause the same spread.

Fake news 'vaccine' works: 'Pre-bunking' game reduces susceptibility to disinformation

An online game in which people play the role of propaganda producers to help them identify real world disinformation has been shown to increase "psychological resistance" to fake news, according to a study of 15,000 participants.

Protein offers protection against nerve degeneration in ALS model

Increasing the levels of the anti-aging protein hormone Klotho improves the neurological deficits and prolongs life span in an experimental model with Amyotrophic Lateral Sclerosis (ALS). In addition, brain immune cells called microglia play an important role in protecting the brain against inflammation and, likely, motor neuron loss in this model.

Robot arm tastes with engineered bacteria

A robotic gripping arm that uses engineered bacteria to "taste" for a specific chemical has been developed by engineers at the University of California, Davis, and Carnegie Mellon University. The gripper is a proof-of-concept for biologically-based soft robotics.
