| Filter membrane renders viruses harmless Posted: 03 Jun 2021 02:13 PM PDT Researchers are developing a new filter membrane that is highly efficient at filtering and inactivating a wide variety of air-borne and water-borne viruses. |
| Front-row view reveals exceptional cosmic explosion Posted: 03 Jun 2021 02:11 PM PDT Scientists have gained the best view yet of the brightest explosions in the universe: A specialised observatory in Namibia has recorded the most energetic radiation and longest gamma-ray afterglow of a so-called gamma-ray burst to date. The observations with the High Energy Stereoscopic System (H.E.S.S.) challenge the idea of how gamma-rays are produced in these colossal stellar explosions which are the birth cries of black holes, as the international team reports. |
| Biocompatible hydrogel materials can rapidly recover from mechanical stress Posted: 03 Jun 2021 02:11 PM PDT Hydrogels are polymer materials made mostly from water. They can be used in a wide range of medical and other applications. However, previous incarnations of the materials suffered from repeated mechanical stress and would easily become deformed. A novel crystal that can reversibly form and deform, allows hydrogels to rapidly recover from mechanical stress. This opens up the use of such biocompatible materials in the field of artificial joints and ligaments. |
| How quantum dots can 'talk' to each other Posted: 03 Jun 2021 08:20 AM PDT A group has worked out theoretically how the communication between two quantum dots can be influenced with light. The team shows ways to control the transfer of information or energy from one quantum dot to another. To this end, the researchers calculated the electronic structure of two nanocrystals, which act as quantum dots. With the results, the movement of electrons in quantum dots can be simulated in real time. |
| Water droplets become hydrobots by adding magnetic beads Posted: 03 Jun 2021 08:19 AM PDT Using a piece of magnet, researchers have designed a simple system that can control the movement of a small puddle of water, even when it's upside down. The new liquid manipulation strategy can have a wide range of applications including cleaning hard-to-reach environments or delivering small objects. |
| Scientists found a new and promising qubit at a place where there is nothing Posted: 03 Jun 2021 08:19 AM PDT In the world of quantum mechanics, researchers can even make empty space, the lack of something, do their bidding. Scientists have now created a new setup to control the absence of electrons in a solid material. They want to use these holes as a basis for a quantum computer. |
| Jets from massive protostars might be very different from lower-mass systems Posted: 03 Jun 2021 08:19 AM PDT A highly-detailed VLA image indicates that the jets of material propelled outward by young stars much more massive than the Sun may be very different from those ejected by less-massive young stars. |
| Coastal flooding increases Bay Area traffic delays and accidents Posted: 03 Jun 2021 08:19 AM PDT Disruptions from sea-level rise and coastal flooding events have significant indirect impacts on urban traffic networks and road safety. |
| Lighting hydrogels via nanomaterials Posted: 02 Jun 2021 02:06 PM PDT Hydrogels are commonly used inside the body to help in tissue regeneration and drug delivery. However, once inside, they can be challenging to control for optimal use. A team of researchers is developing a new way to manipulate the gel -- by using light. |
| Top acoustic amplifier emerges from 50-year-old hypothesis Posted: 02 Jun 2021 06:11 AM PDT Scientists have built the smallest and best acoustic amplifier. And they did it using a concept that was all but abandoned for almost 50 years. |
