Phys.org / Solar orbiter detects ion sorting at the solar wind's magnetic boundary
A Southwest Research Institute (SwRI) study of data from the European Space Agency's (ESA) Solar Orbiter gives the most detailed view of the heliospheric current sheet (HCS) to date. The HCS is a sprawling, undulating surface ...
Phys.org / Algorithm improves detection of differentially expressed genes in large single-cell trajectory data sets
Single-cell RNA sequencing (scRNA-seq) is a method for measuring gene expression in individual cells, allowing observation of various cellular processes, including cell differentiation, the cell cycle and stimulus response, ...
Phys.org / Tiny mirror that controls light in 3D could make microscopes smaller and faster
Researchers use tightly focused laser beams to image biological samples, shape materials with microscopic precision and generate displays. But using those beams in three dimensions requires more than sweeping light from side ...
Medical Xpress / The anti-aging effects of exercise, without exercise: Self-contracting muscle implants give mice a boost
Exercise does more than keep our minds and bodies healthy. It also protects us against the effects of aging. Scientists have developed self-contracting mini-muscle implants that grow their own blood supply and mimic the biological ...
Medical Xpress / COVID's toll on kids was milder than predicted, six-country study finds
Six years after COVID-19 disrupted childhood around the world, new research following the same children from before the pandemic through today finds that the damage was far less widespread than early warnings predicted. A ...
Phys.org / Why some earthquakes caused by fracking come with warning signs
Fracking, the injection of high-pressure fluid to fracture rock and release oil or gas, can trigger earthquakes. While some sites generate small tremors beforehand that may provide an early warning, others produce few or ...
Phys.org / Loss of kelp forests reverberates down to the microbial level
As one moves north, Maine's kelp forests are being overtaken by dense mats of carpet-like turf algae. The steady decline of kelp and transition into this new state are altering the ecosystem all the way down to the microbial ...
Phys.org / Bumblebees may self-medicate when exposed to fungal infections
There is an old saying that nature is the best medicine, and it turns out bumblebees might agree. A new study published in the journal Royal Society Open Science suggests that buff-tailed bumblebees (Bombus terrestris) may ...
Phys.org / Milky Way's own gravity can mimic dark matter clues, stellar stream simulations suggest
Most of the stars in our Milky Way galaxy sit neatly on a flat plane. But the space around our galaxy is much more chaotic. Rogue bands of stars called "stellar streams" orbit the Milky Way much like planets in our solar ...
Phys.org / Precision optics to make plant health visible from space
When the ESA Earth observation mission FLEX launches into space on September 15, 2026, as scheduled, it will carry high-precision optical components from Jena, Germany. Researchers at the Fraunhofer Institute for Applied ...
Tech Xplore / New analysis reveals unexpected vulnerabilities in power grids and other cyber-physical networks
If you wanted to take down a power grid or a network of drones, which part of the system should you attack? Researchers at The University of New Mexico School of Engineering posed the question in hopes of developing better ...
Phys.org / Infection kills gut cells, while diet reshapes existing ones, fruit fly study finds
The intestines rely on different strategies to rebuild themselves in response to diet changes versus infections, according to a new Cornell study—a finding that can shed light on how gut health adapts to harsh conditions, ...
