| With a zap of light, system switches objects' colors and patterns Posted: 04 May 2021 04:16 PM PDT ChromoUpdate is a 'programmable matter' technique to quickly change objects' color. The method uses light to alter the saturation of photochromatic ink on an item's surface and could give product designers a boost in churning out prototypes. |
| New application of AI just removed one of the biggest roadblocks in astrophysics Posted: 04 May 2021 04:16 PM PDT Using neural networks, researchers simulated vast, complex universes in a fraction of the time it takes with conventional methods. |
| Hopkins-led research team takes gene mutation detection in blood to the next level Posted: 04 May 2021 10:57 AM PDT Researchers have developed a new technology to overcome the inefficiencies and high error rates common among next-generation sequencing techniques that have previously limited their clinical application. |
| New neuroimaging technique studies brain stimulation for depression Posted: 04 May 2021 10:57 AM PDT Despite increased use of repetitive transcranial magnetic stimulation in psychiatry, the rates at which patients respond to the therapy and experience remission of often-disabling symptoms have been modest at best. Now, a team of psychiatrists and biomedical engineers applied an emerging functional neuroimaging technology, known as diffuse optical tomography (DOT), to better understand how rTMS works so they can begin to improve the brain stimulation procedure's effectiveness in treating depression. |
| Nanoplastics -- an underestimated problem? Posted: 04 May 2021 08:26 AM PDT Giant vortices of floating plastic trash in the world's oceans with sometimes devastating consequences for their inhabitants - the sobering legacy of our modern lifestyle. Weathering and degradation processes produce countless tiny particles that can now be detected in virtually all ecosystems. But how dangerous are the smallest of them, so-called nanoplastics? |
| Nanoplastics and other harmful pollutants found in disposable face masks Posted: 04 May 2021 08:26 AM PDT Scientists have uncovered potentially dangerous chemical pollutants that are released from disposable face masks when submerged in water. The research reveals high levels of pollutants, including lead, antimony, and copper, within the silicon-based and plastic fibres of common disposable face masks. |
| A sweet solution to hard brain implants Posted: 04 May 2021 08:26 AM PDT By using silicone polymers, scientists have made the softest brain implant to date with the thickness of a thin sewing thread (~0.2 mm), and the consistency of soft pudding - as soft as the brain itself. They were then able to implant it into the brain using a trick from a cookbook. |
| New 'key-hole surgery' technique to extract metals from the Earth Posted: 04 May 2021 08:26 AM PDT Researchers have developed a new method to extract metals, such as copper, from their parent ore body. The research team have provided a proof of concept for the application of an electric field to control the movement of an acid within a low permeability copper-bearing ore deposit to selectively dissolve and recover the metal in situ. |
| Little to no increase in association between adolescents' mental health problems and digital tech Posted: 04 May 2021 08:26 AM PDT A new study suggests that over the past 30 years, there has been little to no increase in the association between adolescents' technology engagement and mental health problems. The study also urges more transparent collaborations between academia and industry. |
| New lunar map to help guide future exploration missions Posted: 04 May 2021 08:26 AM PDT A new map of the Schrodinger basin of the moon could help guide future exploration missions. |
| New synapse-like phototransistor Posted: 04 May 2021 08:26 AM PDT Researchers have developed a breakthrough in energy-efficient phototransistors. Such devices could eventually help computers process visual information more like the human brain and be used as sensors in things like self-driving vehicles. |
| Algorithms improve how we protect our data Posted: 04 May 2021 08:26 AM PDT Scientists have developed algorithms that more efficiently measure how difficult it would be for an attacker to guess secret keys for cryptographic systems. The approach could reduce the computational complexity needed to validate encryption security. |
| Surfaces can be designed with antiviral properties to mitigate COVID-19 Posted: 04 May 2021 08:26 AM PDT If a respiratory droplet from a person infected with COVID-19 lands on a surface, it becomes a possible source of disease spread, because while 99.9 percent of the droplet's liquid content evaporates within minutes, a residual thin film that allows the virus to survive can be left behind. In a new study, researchers explore how the evaporation rate of residual thin films can be accelerated by tuning surfaces' wettability and creating geometric microtextures on them. |
| Chemical 'nose' sniffs critical differences in DNA structures Posted: 04 May 2021 08:25 AM PDT Small changes in the structure of DNA have been implicated in breast cancer and other diseases, but they've been extremely difficult to detect -- until now. Using what they describe as a 'chemical nose,' chemists are able to 'smell' when bits of DNA are folded in unusual ways. |
| Geology helps astronomers find habitable planets Posted: 04 May 2021 08:25 AM PDT Astronomers have identified more than 4,000, and counting, confirmed exoplanets -- planets orbiting stars other than the sun -- but only a fraction have the potential to sustain life. Now, new research is using the geology of early planet formation to help identify those that may be capable of supporting life. |
| Researchers advance 3D printing to aid tissue replacement Posted: 04 May 2021 08:25 AM PDT Researchers are looking into a possible future in which doctors can hit a button to print out a scaffold on their 3-D printers and create custom-made replacement skin, cartilage, or other tissue for their patients. |
| Complex shapes of photons to boost future quantum technologies Posted: 04 May 2021 08:25 AM PDT Researchers have demonstrated how two interfering photons can bunch into various shapes. These complex shapes are beneficial for quantum technologies, such as performing fast photonic quantum computations and safe data transfer. The method opens new possibilities also for creating enhanced measurement and sensing techniques. |
| Artificial intelligence to monitor water quality more effectively Posted: 04 May 2021 08:25 AM PDT Artificial intelligence that enhances remote monitoring of water bodies - highlighting quality shifts due to climate change or pollution - has been developed. |
| Carbon dioxide catalysis made more accessible Posted: 30 Apr 2021 09:04 AM PDT Many industrial processes emit carbon dioxide into the atmosphere. Unfortunately, however, current electrochemical separation methods are expensive and consume large amounts of power. They also require expensive and rare metals as catalysts. A study now describes a new aerogel electrocatalyst formed from an inexpensive metal alloy, which enables highly efficient electrochemical conversion of carbon dioxide. The main product is formic acid, which is a nontoxic basic chemical. |
