| Ground and satellite observations map building damage after Beirut explosion Posted: 22 Apr 2021 09:36 AM PDT Days after the 4 August 2020 massive explosion at the port of Beirut in Lebanon, researchers were on the ground mapping the impacts of the explosion in the port and surrounding city. The goal was to document and preserve data on structural and façade damage before rebuilding. |
| Fighting harmful bacteria with nanoparticles Posted: 22 Apr 2021 09:36 AM PDT Multi-resistant pathogens are a serious and increasing problem in today's medicine. Where antibiotics are ineffective, these bacteria can cause life-threatening infections. Researchers are currently developing nanoparticles that can be used to detect and kill multi-resistant pathogens that hide inside our body cells. The team published the study in the current issue of the journal Nanoscale. |
| The future looks bright for infinitely recyclable plastic Posted: 22 Apr 2021 07:28 AM PDT Plastics are ubiquitous, but they're not practical. Less than 10% are recycled, and the other approximately 8 billion tons are creating a pollution crisis. Researchers are determined to change that. A new analysis shows producing and recycling their game-changing new plastic could be easy and cheap enough to leave old plastics in the dust. |
| Faster air exchange in buildings not always beneficial for coronavirus levels Posted: 22 Apr 2021 06:38 AM PDT Vigorous and rapid air exchanges might not always be a good thing when it comes to levels of coronavirus particles in a multiroom building, according to a new modeling study. Particle levels can spike in downstream rooms shortly after rapid ventilation. |
| Average-risk individuals may prefer stool-based test over colonoscopy for cancer screening Posted: 22 Apr 2021 06:38 AM PDT When given a choice, most individuals with an average risk of colorectal cancer said they would prefer a stool-based screening test for colorectal cancer over colonoscopy, the method most often recommended by health care providers. |
| Collaborative research could help fine-tune the production of antimalarials, chemo drugs Posted: 21 Apr 2021 05:01 PM PDT Much of common pharmaceutical development today is the product of laborious cycles of tweaking and optimization. In each drug, a carefully concocted formula of natural and synthetic enzymes and ingredients works together to catalyze a desired reaction. But in early development, much of the process is spent determining what quantities of each enzyme to use to ensure a reaction occurs at a specific speed. |
| Detailed look at intriguing property of chiral materials Posted: 21 Apr 2021 01:00 PM PDT A new study is advancing scientists' understanding of magneto-chiral dichroism. The research focuses on light-matter interactions in chiral materials under a magnetic field. |
| Using floodwaters to weather droughts Posted: 21 Apr 2021 12:12 PM PDT Using a new computer framework, scientists are able to project future floodwaters under a changing climate. The approach could help California water managers plan for and redirect floodwaters toward groundwater aquifers, alleviating both flood and drought risks. |
| Scientists capture image of an electron's orbit within an exciton Posted: 21 Apr 2021 12:12 PM PDT Researchers have captured an image showing the internal orbits, or spatial distribution, of particles in an exciton - a goal that had eluded scientists for almost a century. |
| Mechanical engineers develop new high-performance artificial muscle technology Posted: 21 Apr 2021 12:12 PM PDT Researchers have developed a new, high-performance artificial muscle technology. The new technology enables more human-like motion due to its flexibility and adaptability, but outperforms human skeletal muscle in several metrics. |
| Aerial photos uncover an invisible fault in Chinese city Posted: 21 Apr 2021 12:12 PM PDT Decades-old aerial photos of Yudong District, Datong City in Shanxi Province, Northern China have helped researchers in their search for a fault hidden underneath the city's buildings and cement roads, researchers said. |
| 'Fingerprint' for 3D printer accurate 92% of time Posted: 21 Apr 2021 09:47 AM PDT New research shows 3D printers can be identified by thermodynamic properties, which could could aid intellectual property, security. |
| A growing problem of 'deepfake geography': How AI falsifies satellite images Posted: 21 Apr 2021 09:46 AM PDT Using satellite photos of three cities and drawing upon methods used to manipulate video and audio files, a team of researchers set out to identify new ways of detecting fake satellite photos and warn of the dangers of falsified geospatial data. |
| Pepper the robot talks to itself to improve its interactions with people Posted: 21 Apr 2021 09:46 AM PDT Ever wondered why your virtual home assistant doesn't understand your questions? Or why your navigation app took you on the side street instead of the highway? Researchers have now designed a robot that 'thinks out loud' so that users can hear its thought process and better understand the robot's motivations and decisions. |
| Jane Austen quote encoded in a polymer Posted: 21 Apr 2021 09:46 AM PDT Using a novel molecular-data-storage technique, researchers have encoded a quote from Jane Austen's classic novel Mansfield Park in a series of oligomers, which a third party could read back without prior knowledge of the structures that encoded the passage. |
| Laser paintbrush used to create miniature masterpieces Posted: 19 Apr 2021 08:01 AM PDT Researchers are blurring the lines between science and art by showing how a laser can be used to create artistic masterpieces in a way that mirrors classical paints and brushes. The new technique not only creates paint-like strokes of color on metal but also offers a way to change or erase colors. |
