| Single test for over 50 genetic diseases will cut diagnosis from decades to days Posted: 04 Mar 2022 11:46 AM PST A single DNA test has been developed that can screen a patient's genome for over 50 genetic neurological and neuromuscular diseases such as Huntington's disease, muscular dystrophies and fragile X syndrome. The new test avoids a 'diagnostic odyssey' for patients that can take decades. The team has shown that the test is accurate. They are now working on validations to make it available in pathology labs. They expect it to be standard in global pathology labs within five years. |
| Making diversity, equity, inclusion integral part of physics education Posted: 04 Mar 2022 09:40 AM PST While many physics instructors are beginning to incorporate lessons on diversity, equity, and inclusion in the classroom, it can often feel like an add-on rather than an integral component of becoming a physicist. Scientists are helping to change this by presenting discussions and activities on DEI as a fundamental and essential part of physics training. The team created two approaches for DEI curriculum, replacing a question on a weekly homework assignment with a reflection essay on a topic important to physicists and including activities and discussions during a two-day unit on representation. |

| 'Fingerprint' machine learning technique identifies different bacteria in seconds Posted: 04 Mar 2022 07:10 AM PST Bacterial identification can take hours and often longer -- precious time when diagnosing infections and selecting appropriate treatments. There may be a quicker, more accurate process. By teaching a deep learning algorithm to identify the 'fingerprint' spectra of the molecular components of various bacteria, the researchers could classify various bacteria in different media with accuracies up to 98%. |
| Predicting solar cell performance from terahertz and microwave spectroscopy Posted: 04 Mar 2022 07:09 AM PST Many semiconducting materials are possible candidates for solar cells. In recent years, perovskite semiconductors in particular have attracted attention, as they are both inexpensive and easy to process and enable high efficiencies. Now a new study shows how terahertz (TRTS) and microwave spectroscopy (TRMC) can be used to reliably determine the mobility and lifetime of the charge carriers in new semiconducting materials. Using these measurement data it is possible to predict the potential efficiency of the solar cell in advance and to classify the losses in the finished cell. |

| Robot 'bugs' that can go just about anywhere Posted: 03 Mar 2022 04:14 PM PST Researchers have created tiny bug-inspired robots that can carry out tasks in hard-to-reach spaces and inhospitable environments. |
| Scooting to a new era in active transportation Posted: 03 Mar 2022 04:14 PM PST In recent years, shared electric scooters (e-scooters) have taken cities by storm. But how are people using this new mode of transportation? A new study has some interesting data to share on e-scooter users. Self-reported safety behaviors didn't always match with observations: the reported use of helmets (13% while riding) far outweighed researchers' observations in Salt Lake City (2% of riders) or Tucson (2% of riders). |
| How triple-pane windows stop energy (and money) from flying out the window Posted: 03 Mar 2022 01:20 PM PST Next generation triple-pane windows provide builders with lower cost options and help homeowners conserve energy, reduce noise, and lower home energy bills. |
| Magnetic excitations could provide information transfer without heat loss Posted: 03 Mar 2022 01:20 PM PST Just as electrons flow through an electrical conductor, magnetic excitations can travel through certain materials. Such excitations, known in physics as 'magnons' in analogy to the electron, could transport information much more easily than electrical conductors. An international research team has now made an important discovery on the road to such components, which could be highly energy-efficient and considerably smaller. |
| How can the computer chip predict the future of gene synthesis? Posted: 03 Mar 2022 01:20 PM PST Creating synthetic life could be easily within our grasp soon based on a comparison with the evolution of computer chips. Computer programming and gene synthesis appear to share little in common. But according to an expert, leaps forward in technology in the former make him optimistic that wide scale gene manufacture is achievable. |
