New algorithm may help people store more pictures, share videos faster
The world produces about 2.5 quintillion bytes of data every day. Storing and transferring all of this enormous—and constantly growing—number of images, videos, Tweets, and other forms of data is becoming a significant challenge, one that threatens to undermine the growth of the internet and thwart the introduction of new technologies, such as the Internet of Things.

Quick liquid packaging: Encasing water silhouettes in 3-D polymer membranes for lab-in-a-drop experiments
The ability to confine water in an enclosed compartment without directly manipulating it or using rigid containers is an attractive possibility. In a recent study, Sara Coppola and an interdisciplinary research team in the departments of Biomaterials, Intelligent systems, Industrial Production Engineering and Advanced Biomaterials for Healthcare in Italy, proposed a water-based, bottom-up approach to encase facile, short-lived water silhouettes in a custom-made adaptive suit.

Desalinating water in a greener and more economical way
We know that excessive consumption, industrial activity and growth in the global population are some of the factors threatening access to drinking water for an increasing proportion of people around the world. According to UNESCO figures from 2012, almost 700 million people suffer from limited access to water—and that number could rise to 1.8 billion by 2025. Desalination and the treatment of industrial wastewater can produce large amounts of drinking water, and these methods are already used in many countries and regions such as the United Arab Emirates, Saudi Arabia, China, Europe and the U.S.. However, existing systems are costly and use a lot of energy. Jeff Ong, from EPFL's Laboratory of Inorganic Synthesis and Catalysis, has developed a water treatment machine that combines the benefits of all of the main technologies currently being used while offering improved performance. For example, the prototype removes more than 99.9 percent of the salt from seawater with the same throughput but using less energy. The system will be tested in real-world conditions this year.

A new mechanism for accessing damaged DNA
UV light damages the DNA of skin cells, which can lead to skin cancer. But this process is counteracted by DNA repair machinery, acting as a molecular sunscreen. It has been unclear, however, how repair proteins work on DNA tightly packed in chromatin, where access to DNA damage is restricted by protein packaging. Using cryo electron microscopy, researchers from the Thomä group at the Friedrich Miescher Institute for Biomedical Research (FMI) have identified a new mechanism whereby repair proteins detect and bind to damaged DNA that is densely packed in nucleosomes.

Transgenic fungus rapidly killed malaria mosquitoes in West African study
According to the World Health Organization, malaria affects hundreds of millions of people around the world, killing more than 400,000 annually. Decades of insecticide use has failed to control mosquitoes that carry the malaria parasite and has led to insecticide-resistance among many mosquito strains. In response, scientists began genetically modifying mosquitoes and other organisms that can help eradicate mosquitoes. Until now, none of these transgenic approaches made it beyond laboratory testing.

'Neural Lander' uses AI to land drones smoothly
Landing multi-rotor drones smoothly is difficult. Complex turbulence is created by the airflow from each rotor bouncing off the ground as the ground grows ever closer during a descent. This turbulence is not well understood nor is it easy to compensate for, particularly for autonomous drones. That is why takeoff and landing are often the two trickiest parts of a drone flight. Drones typically wobble and inch slowly toward a landing until power is finally cut, and they drop the remaining distance to the ground.

Growing up high: Neurobiological consequences of adolescent cannabis use
About one in five Canadian adolescents uses cannabis (19% of Canadians aged 15-19), and its recent legalization across the country warrants investigation into the consequence of this use on the developing brain. Adolescence is associated with the maturation of cognitive functions, such as working memory, decision-making, and impulsivity control. This is a highly vulnerable period for the development of the brain as it represents a critical period wherein regulatory connection between higher-order regions of the cortex and emotional processing circuits deeper inside the brain are established. It is a period of strong remodeling, making adolescents highly vulnerable to drug-related developmental disturbances. Research presented by Canadian neuroscientists Patricia Conrod, Steven Laviolette, Iris Balodis and Jibran Khokhar at the 2019 Canadian Neuroscience Meeting in Toronto on May 25 featured recent discoveries on the effects of cannabis on the adolescent brain.

Scientists capture first-ever video of body's safety test for T-cells
For the first time, immunologists from The University of Texas at Austin have captured on video what happens when T-cells—the contract killers of the immune system, responsible for wiping out bacteria and viruses—undergo a type of assassin-training program before they get unleashed in the body. A new imaging technique that allowed for the videos, described today in the journal Nature Communications, holds promise for the fight against autoimmune disorders such as Type 1 diabetes.

For many HIV+ women, daily survival takes precedence over viral suppression
According to scientists who study women infected with HIV, statistics often paint an impressionist view of the lives of these women that misses the granular detail that tells the real story. The imprecise big picture is that most of this population is doing a good job at suppressing the virus, but facts gathered on the ground show that many struggle with issues of daily living that can make taking a pill to keep HIV at bay difficult.

Polymers jump through hoops on pathway to sustainable materials
Recyclable plastics that contain ring-shaped polymers may be a key to developing sustainable synthetic materials. Despite some promising advances, researchers said, a full understanding of how to processes ring polymers into practical materials remains elusive. In a new study, researchers identified a mechanism called "threading" that takes place when a polymer is stretched—a behavior not witnessed before. This new insight may lead to new processing methods for sustainable polymer materials.

Early dengue virus infection could 'defuse' Zika virus
"We now know for sure that Zika virus infection during pregnancy can affect the unborn foetus in such a way that the child develops microcephaly and other severe symptoms," explains Prof Felix Drexler, a virologist at Charité who has been developing diagnostic tests for Zika and other viruses at the DZIF. Just a few years ago, pictures of affected newborns were cause for worldwide dismay and perplexity. "However, what we did not understand then was that high incidence of microcephaly seemed to occur particularly in northeastern Brazil," says Drexler. Why are expecting mothers in these regions at a higher risk of developing a severe Zika-associated disease than in other regions? The scientists consequently began to search for cofactors that have an influence on whether a Zika infection during pregnancy will develop fatal consequences or not.

Dangerous pathogens use this sophisticated machinery to infect hosts
Gastric cancer, Q fever, Legionnaires' disease, whooping cough—though the infectious bacteria that cause these dangerous diseases are each different, they all utilize the same molecular machinery to infect human cells. Bacteria use this machinery, called a Type IV secretion system (T4SS), to inject toxic molecules into cells and also to spread genes for antibiotic resistance to fellow bacteria. Now, researchers at Caltech have revealed the 3-D molecular architecture of the T4SS from the human pathogen Legionella pneumophila with unprecedented details. This could in the future enable the development of precisely targeted antibiotics for the aforementioned diseases.

Experimental brain-controlled hearing aid decodes, identifies who you want to hear
Our brains have a remarkable knack for picking out individual voices in a noisy environment, like a crowded coffee shop or a busy city street. This is something that even the most advanced hearing aids struggle to do. But now Columbia engineers are announcing an experimental technology that mimics the brain's natural aptitude for detecting and amplifying any one voice from many. Powered by artificial intelligence, this brain-controlled hearing aid acts as an automatic filter, monitoring wearers' brain waves and boosting the voice they want to focus on.

Extraordinarily transparent compact metallic metamaterials
In materials science, achromatic optical components can be designed with high transparency and low dispersion. Materials scientists have shown that although metals are highly opaque, densely packed arrays of metallic nanoparticles with more than 75 percent metal by volume can become more transparent to infrared radiation than dielectrics such as germanium. Such arrays can form effective dielectrics that are virtually dispersion-free across ultra-broadband ranges of wavelengths to engineer a variety of next-generation metamaterial-based optical devices.

Just like toothpaste: Fluoride radically improves the stability of perovskite solar cells
Solar cells made of perovskite hold much promise for the future of solar energy. The material is cheap, easy to produce and almost as efficient as silicon, the material traditionally used in solar cells. However, perovskite degrades quickly, severely limiting its efficiency and stability over time. Researchers from Eindhoven University of Technology, energy research institute DIFFER, Peking University and University of Twente have discovered that adding a small amount of fluoride to the perovskite leaves a protective layer, increasing stability of the materials and the solar cells significantly. The solar cells retain 90 percent of their efficiency after 1000 hours operation at various extreme testing conditions. The findings are published today in the leading scientific journal Nature Energy.

A new treatment for stroke in mice reduces brain damage and promotes motor recovery
Brain injuries like stroke can be debilitating and require time-sensitive treatment. Clotting factors like thrombin are commonly administered to patients, but there are many other stroke-related signs that can be targeted, such as swelling and ion imbalances in the surrounding fluids. New research shows that brain fluids can be normalized with adrenergic receptor antagonists, a combination of drugs to block the activity of (nor)adrenaline in the brain. This experimental treatment for stroke aided motor recovery and reduced cell death in mice, as reported in the Proceedings of the National Academy of Sciences on May 13.
