| Modeling a circular economy for electronic waste Posted: 21 Jun 2021 02:41 PM PDT New research develops a framework to understand the choices an electronic waste recycler has to make and the role that digital fraud prevention could have in preventing dishonest recycling practices. |
| Civil engineers examine urban cooling strategies using reflective surfaces Posted: 21 Jun 2021 02:41 PM PDT Researchers used a Computational Fluid Dynamics model to find ways to decrease cost and increase usage of cooler surfaces. The paper examined the possibility of applying cooler surfaces to just half the surfaces in a city. |
| Landmark field trials show potential of gene editing Posted: 21 Jun 2021 01:05 PM PDT Field trials investigating healthy compounds in agronomically important brassica crops have underlined the 'immense potential' of gene editing technology, say researchers. |
| Database of vegetation of planet Earth Posted: 21 Jun 2021 01:05 PM PDT It's a treasure trove of data: the global vegetation database 'sPlotOpen' is now freely accessible. It contains balanced, representative data on vegetation from 114 countries and from all climate zones on Earth. |
| Posted: 21 Jun 2021 01:05 PM PDT The word 'tsunami' brings immediately to mind the havoc that can be wrought by these uniquely powerful waves. The tsunamis we hear about most often are caused by undersea earthquakes, and the waves they generate can travel at speeds of up to 250 miles per hour and reach tens of meters high when they make landfall and break. They can cause massive flooding and rapid widespread devastation in coastal areas, as happened in Southeast Asia in 2004 and in Japan in 2011. |
| Exposure to pollutants, increased free-radical damage speeds up aging Posted: 21 Jun 2021 01:05 PM PDT A new study suggests that unrepaired DNA damage can increase the speed of aging. |
| Computers help researchers find materials to turn solar power into hydrogen Posted: 21 Jun 2021 10:39 AM PDT Researchers report that they have taken a step toward overcoming the challenge of inexpensive hydrogen production by using supercomputers to find materials that could help accelerate hydrogen separation when water is exposed to light, a process called photocatalysis. |
| Engineers create 'seeds' for growing near-perfect 2D perovskite crystals Posted: 21 Jun 2021 10:39 AM PDT Engineers have created microscopic seeds for growing remarkably uniform 2D perovskite crystals that are both stable and highly efficient at harvesting electricity from sunlight. |
| New research unlocks the mystery of New England's beaches Posted: 21 Jun 2021 10:39 AM PDT Until now, the factors governing which beaches slope gradually to the sea and which ones end abruptly in a steep drop-off have been largely unknown. However, new research reveals, with unprecedented detail, how the grain size of beach sand relates to the slope of the beach itself. These new findings are critical to understanding how New England's beaches will respond to both rising sea levels and increased storm activity. |
| Scientists develop energy saving technique paving way for a carbon neutral society Posted: 21 Jun 2021 09:37 AM PDT Researchers have discovered a method which will allow for faster communication systems and better energy saving electronics. |
| Projections of US high-tide flooding show rapid increases and extreme months Posted: 21 Jun 2021 09:37 AM PDT In the mid-2030s, multiple United States coastal regions may see rapid increases in the number of high-tide flooding (HTF) days, according to a new study. The combined effects of sea-level rise and natural fluctuations in tidal range are anticipated to cause tipping points in the frequency of HTF. |
| New modeling technique shows greater likelihood, frequency of urban extreme heat events Posted: 21 Jun 2021 09:37 AM PDT This model addresses the fact that most traditional climate models effectively ignore cities entirely, causing them to underestimate the frequency and severity of urban heat waves. Urban areas make up only 2-3% of the earth's land, so their effect on global models is negligible, but more than half of the world's population lives in urban areas, so their impact is significant. |
| A bright future: Using visible light to decompose CO2 with high efficiency Posted: 21 Jun 2021 07:42 AM PDT To tackle the challenge of global warming, scientists have been looking into green and sustainable methods of breaking down carbon dioxide in emissions and in the atmosphere. Now, a group of researchers have developed a novel, easy to synthesize composite compound that enables the efficient use of solar energy to reduce carbon dioxide, taking us one step closer to achieving a green economy. |
| Posted: 21 Jun 2021 07:42 AM PDT Scientists have used a compound made from a starch derivative and baking soda to help convert mechanical to electrical energy. The approach is cost-effective and biocompatible, and can help charge low-energy electronics like calculators and watches. |
| New geochemical study confirms cause of end-Permian mass extinction event Posted: 21 Jun 2021 06:46 AM PDT Researchers found a direct link between global dispersion of nickel-rich aerosols, ocean chemistry changes and the end-Permian mass extinction event that took place 251 million years ago. |
| Smaller bodies, longer wings, earlier migrations: Untangling the multiple impacts of climate warming Posted: 21 Jun 2021 05:41 AM PDT When a research team reported last year that North American migratory birds have been getting smaller over the past four decades and that their wings have gotten a bit longer, the scientists wondered if they were seeing the fingerprint of earlier spring migrations. |
| New software for designing sustainable cities Posted: 21 Jun 2021 05:40 AM PDT By 2050, more than 70% of the world's population will live in cities. Researchers have developed software that shows city planners where to invest in nature to improve people's lives and save billions of dollars. |
| Scientists detect signatures of life remotely Posted: 18 Jun 2021 10:39 AM PDT It could be a milestone on the path to detecting life on other planets: Scientists detect a key molecular property of all living organisms from a helicopter flying several kilometers above ground. The measurement technology could also open up opportunities for remote sensing of the Earth. |
