| Low-cost, 3D printed device may broaden focused ultrasound use Posted: 22 Feb 2022 09:50 AM PST Medical researchers have developed a method for producing a low-cost, easy-to-use focused ultrasound device that can help open up the blood-brain barrier for non-invasive procedures and diagnostics. |
| Building artificial nerve cells Posted: 22 Feb 2022 09:13 AM PST For the first time, researchers demonstrate an artificial organic neuron, a nerve cell, that can be integrated with a living plant and an artificial organic synapse. Both the neuron and the synapse are made from printed organic electrochemical transistors. |
| Sonic advance: How sound waves could help regrow bones Posted: 22 Feb 2022 09:12 AM PST Researchers have used sound waves to turn stem cells into bone cells, in a tissue engineering advance that could one day help patients regrow bone lost to cancer or degenerative disease. |
| New material offers remarkable combo of toughness and stretchiness Posted: 21 Feb 2022 08:54 AM PST Researchers have created new materials that are very stretchable and extremely tough. The new materials fall under the broader category of ionogels, which are polymer networks that contain salts that are liquid at room temperature. |
| Bacteria upcycle carbon waste into valuable chemicals Posted: 21 Feb 2022 08:54 AM PST Researchers engineered a strain of bacteria to break down carbon dioxide (CO2), converting it into commonly used, expensive industrial chemicals. The carbon-negative approach removes CO2 from the atmosphere and bypasses using fossil fuels to generate these chemicals. |
| A 'hot Jupiter’s' dark side is revealed in detail for first time Posted: 21 Feb 2022 08:54 AM PST Astronomers have obtained the clearest view yet of the perpetual dark side of an exoplanet that is 'tidally locked' to its star. The planet is WASP-121b, a massive gas giant nearly twice the size of Jupiter. |
| Can machine-learning models overcome biased datasets? Posted: 21 Feb 2022 08:54 AM PST Researchers have applied the tools of neuroscience to study when and how an artificial neural network can overcome bias in a dataset. They found that data diversity, not dataset size, is key and that the emergence of certain types of neurons during training plays a major role in how well a neural network is able to overcome dataset bias. |
| Versatile ‘nanocrystal gel’ could enable advances in energy, defense and telecommunications Posted: 18 Feb 2022 12:30 PM PST New applications in energy, defense and telecommunications could receive a boost after a team created a new type of 'nanocrystal gel' -- a gel composed of tiny nanocrystals each 10,000 times smaller than the width of a human hair that are linked together into an organized network. |
