Published Engineers harvest abundant clean energy from thin air, 24/7
(via sciencedaily.com) Original source A team of engineers has recently shown that nearly any material can be turned into a device that continuously harvests electricity from humidity in the air. Researchers describe the 'generic Air-gen effect'-- nearly any material can be engineered with nanopores to harvest, cost effective, scalable, interruption-free electricity. The secret lies in being able to pepper the material with nanopores less than 100 nanometers in diameter.
Published Medical 'microrobots' could one day treat bladder disease, other human illnesses
(via sciencedaily.com) Original source Engineers have designed a new class of 'microrobots' several times smaller than the width of a human hair that may be able to treat human illnesses like interstitial cystitis -- a painful bladder disease that affects millions of Americans.
Published New method predicts extreme events more accurately
(via sciencedaily.com) Original source A new study has used global storm-resolving simulations and machine learning to create an algorithm that can deal separately with two different scales of cloud organization: those resolved by a climate model, and those that cannot be resolved as they are too small. This new approach addresses the missing piece of information in traditional climate model parameterizations and provides a way to predict precipitation intensity and variability more precisely.
Published New potential drug target for Alzheimer's disease
(via sciencedaily.com) Original source Tau protein is implicated in many neurogenerative diseases, including Alzheimer's. New findings point to a new potential drug target to slow the progress of the disease: the enzymes responsible for sulfation called heparan sulfate 3-O transferases.
Published Quantum matter breakthrough: Tuning density waves
(via sciencedaily.com) Original source Scientists have found a new way to create a crystalline structure called a 'density wave' in an atomic gas. The findings can help us better understand the behavior of quantum matter, one of the most complex problems in physics.
Published 'Sustainable' condenser tumble dryers create hundreds of tons of waterborne microfiber pollution
(via sciencedaily.com) Original source A new study has revealed that drying laundry using a condenser tumble dryer leads to hundreds of tons of potentially harmful microfibers being released into waterways and oceans across the UK and Europe.
Published Simultaneous atmospheric and marine observations directly beneath a violent, Category 5 typhoon in the North-West Pacific
(via sciencedaily.com) Original source Scientists have successfully conducted a simultaneous marine and atmospheric measurements at multiple locations directly beneath a violent, Category 5, which is the strongest class, typhoon in the North-West Pacific, before it reached land.
Published Flexing crystalline structures provide path to a solid energy future
(via sciencedaily.com) Original source Researchers have uncovered the atomic mechanisms that make a class of compounds called argyrodites attractive candidates for both solid-state battery electrolytes and thermoelectric energy converters. The discoveries -- and the machine learning approach used to make them -- could help usher in a new era of energy storage for applications such as household battery walls and fast-charging electric vehicles.
Published Researchers examine cooling power plants with brackish groundwater
(via sciencedaily.com) Original source Nontraditional water sources can be deployed to help cope with climate-induced water risks and tackle the increasing water demand for decarbonization of fossil fuel-fired power plants, but that could increase the cost of electricity generation by 8 percent to 10 percent.
Published Researchers find new mechanism for sodium salt detoxification in plants
(via sciencedaily.com) Original source A team of researchers has found a mechanism in thale cress (Arabidopsis thaliana) which enables plants to provide protection against salt stress for their sensitive stem cells in the meristem at the root tip.
Published Researchers build bee robot that can twist
(via sciencedaily.com) Original source A robotic bee that can fly fully in all directions has been developed. With four wings made out of carbon fiber and mylar as well as four light-weight actuators to control each wing, the Bee++ prototype is the first to fly stably in all directions. That includes the tricky twisting motion known as yaw, with the Bee++ fully achieving the six degrees of free movement that a typical flying insect displays.
Published CT scan best at predicting heart disease risk in middle age
(via sciencedaily.com) Original source CT scans are better at predicting a middle-aged person's risk for a heart disease, such as a heart attack, than genetics, reports a new study. Conventional measures of risk factor levels include blood pressure and cholesterol. Scientists had hoped genetics could better predict risk than conventional measure, but only when considering CT scan, half the study participants moved into the high-risk group.
Published How a drought affects trees depends on what's been holding them back
(via sciencedaily.com) Original source Droughts can be good for trees. Certain trees, that is. Contrary to expectation, sometimes a record-breaking drought can increase tree growth. Why and where this happens is the subject of a new article.
Published Fluorine-based new drug synthesis at lightning speed
(via sciencedaily.com) Original source Researchers synthesize fluorine-based compound via rapid biphasic (gas and liquid) mixing.
Published What you count is not necessarily what counts
(via sciencedaily.com) Original source Seawater is full of bacteria, hundreds of thousands live in every liter. But the sheer number of bacteria living in the water does not necessarily mean a lot. More important is how active they are and how quickly they duplicate.
Published Earlier snowpack melt in Western US could bring summer water scarcity
(via sciencedaily.com) Original source Mountain snowpack, typically seen as the water tower of the Western United States and Canada, is in decline, according to a new study. Researchers created the Snow Storage Index to assess snow water storage from 1950-2013 and found that storage has significantly declined in more than 25% of the Mountain West, in part because more snow is melting during winter and spring.
Published Communities should reconsider walking away from curbside recycling, study shows
(via sciencedaily.com) Original source Researchers took a deep dive into the economic and environmental value of community recycling efforts and compared it to the value of other climate change mitigation practices, concluding it provides a return on investment.
Published New supply chain model to empower seabound hydrogen economy
(via sciencedaily.com) Original source A team of researchers has created a new supply chain model which could empower the international hydrogen renewable energy industry.
Published Ancient climate change solves mystery of vanished South African lakes
(via sciencedaily.com) Original source New evidence for the presence of ancient lakes in some of the most arid regions of South Africa suggests that Stone Age humans may have been more widespread across the continent than previously thought.
Published Half of world's largest lakes losing water
(via sciencedaily.com) Original source Fifty-three percent of the world's largest freshwater lakes are in decline, storing less water than they did three decades ago, according to a new study. The study analyzed satellite observations dating back decades to measure changes in water levels in nearly 2,000 of the world's biggest lakes and reservoirs. It found that climate change, human consumption and sedimentation are responsible.
