Attitudes toward online learning improve post-pandemic, according to survey

Credit: Pixabay/CC0 Public Domain Positive attitudes toward online learning have increased to their highest levels yet among learners who use it, according to Wiley’s annual Voice of the Online Learner report, issued today. The vast majority—94%—of online learners in the survey said they have a positive or very positive view of online learning, up from … Read more

Shortening the juvenile period for citrus crops to improve food stability

Horticulture Research (2022). DOI: 10.1093/hr/uhac056″ width=”800″ height=”530″/> ToFT and AtFT promote early flowering in transgenic and transgrafted tomato. (a) Phenotypes of 35S:ToFT transgenic tomato. (b) Number of days to flowering and number of internodes in 35S:ToFT transgenic tomato and the control from seed sowing to flowering. Fifteen plants of each genotype were used for statistical … Read more

Lab successfully demonstrates new technique to improve particle beams

The beam particles each emit ultrafast light pulses as they pass through a special magnet called a pickup undulator (bottom right). Information about each particle’s energy or trajectory error is encoded in its light pulse. The light pulses are captured, focused and tuned by various light optics. The particles then interact with their own pulses … Read more

DOI: 10.1038/s41565-022-01146-9 Therapeutics based on messenger RNA, or mRNA, can potentially treat a wide range of maladies, including cancer, genetic diseases, and as the world has developed in recent years, deadly viruses. To work, … Read more

Online platform designed to improve reproducibility, scientific collaborations

Genomic wet-labs are incredibly complex operations. Now a team of researchers, assisted by Penn State’s Institute for Computational and Data Sciences’ RISE engineers, have developed an online platform to help scientists keep track of those complex processes, making them more efficient and less costly while making their experiments more reproducible for other teams.

Why can’t smoggy Southern California improve air quality? Local regulators blame the federal government

Credit: Unsplash/CC0 Public Domain With smoggy Southern California poised to miss a critical clean air goal next year, local regulators are now threatening to sue the Environmental Protection Agency, saying the federal government has made their job “impossible.” The South Coast Air Quality Management District recently notified EPA Administrator Michael Regan that it intends to … Read more

Biologists examine low-cost ways to improve urban streams

Hamilton County Conservation District staff and volunteers survey the Cooper Creek in a pilot project to demonstrate that adding timber in select places upstream can create habitat for fish and other aquatic life.

New control electronics for quantum computers that improve performance, cut costs

Gustavo Cancelo led a team of Fermilab engineers to create a new compact electronics board: It has the capabilities of an entire rack of equipment that is compatible with many designs of superconducting qubits at a fraction of the cost. Credit: Ryan Postel, Fermilab When designing a next-generation quantum computer, a surprisingly large problem is … Read more

Unexpected light behavior may be harnessed to improve optical communications and sensors

The NIST team directed light into an ultrathin layer of silicon nitride etched with grooves to create a diffraction grating. If the separation between the grooves and the wavelength of light is carefully chosen, the intensity of light declines much more slowly, linearly rather than exponentially. Credit: S. Kelley/NIST Shine a flashlight into a murky … Read more
