But bikes need to be restored at bike ports every now and then. Calculating the optimal way to restore bicycles is time consuming and computationally expensive. Recently, researchers have built upon their previous optimization algorithm to propose two strategies to reduce computational costs while maintaining the performance of the algorithm. |
| Hubble reveals surviving companion star in aftermath of supernova Posted: 05 May 2022 08:47 AM PDT It's not unheard of to find a surviving star at the scene of a titanic supernova explosion, which would be expected to obliterate everything around it, but new research has provided a long-awaited clue to a specific type of stellar death. In some supernova cases, astronomers find no trace of the former star's outermost layer of hydrogen. What happened to the hydrogen? Suspicions that companion stars are responsible -- siphoning away their partners' outer shell before their death -- are supported by the recent identification of a surviving companion star on the scene of supernova 2013ge. |

| 'Smart' diaper for bedside urine testing Posted: 05 May 2022 08:46 AM PDT Urine can reveal a lot about a person's health. But physicians don't currently have a convenient or fast way of tracking the concentration of important compounds in their patients' urine. Now, researchers have designed a flexible sensor that fits in a diaper, measures multiple components in urine and can share those results over Bluetooth to provide real-time bedside analyses for incontinent, elderly or infant patients. |
| Wearable, inexpensive robotic sleeve for lymphedema treatment Posted: 05 May 2022 08:46 AM PDT Researchers have developed a soft robotic sleeve controlled with a microfluidic chip that reduces cost, weight, and power consumption for treatment of lymphedema. The prototype is more portable than previous devices, and the underlying mechanisms can extend to other treatments, such as prosthetics. The microfluidic chip has 16 channels, each with a different resistance. The differing resistances create a time delay between the flow through each channel, causing balloons in the sleeve to sequentially inflate and push fluid upwards, out of the arm. |
| Researchers create flat magic window with liquid crystals Posted: 05 May 2022 07:21 AM PDT Researchers have used liquid crystals to create a flat magic window -- a transparent device that produces a hidden image when light shines on it. The process for creating transparent liquid crystal magic windows can produce any desired image. The process can also be used to create magic mirrors that reflect, rather than transmit, light to create an image. The technology represents a new twist on a very old light trick, originating thousands of years ago in China and Japan. |
