New material offers remarkable combo of toughness and stretchiness
Researchers have created new materials that are very stretchable and extremely tough. “Materials that can be deformed, but that are difficult to break or tear, are desirable,” says Michael Dickey, co-corresponding author of a paper on the work and the Camille & Henry Dreyfus Professor of Chemical and Biomolecular Engineering at North Carolina State University.

A ‘hot Jupiter’s’ dark side is revealed in detail for first time: The planet’s night side likely hosts iron clouds, titanium rain, and winds that dwarf Earth’s jetstream.
MIT astronomers have obtained the clearest view yet of the perpetual dark side of an exoplanet that is “tidally locked” to its star. Their observations, combined with measurements of the planet’s permanent day side, provide the first detailed view of an exoplanet’s global atmosphere. “We’re now moving beyond taking isolated snapshots of specific regions of […]
Enzalutamide Rechallenge Yields Small PFS Boost in Metastatic Prostate Cancer
In patients with metastatic castration-resistant prostate cancer (CRPC) who have progressed on enzalutamide (Xtandi), those who continued the treatment in combination with docetaxel and prednisolone saw improved progression-free survival (PFS), the phase IIIb PRESIDE study found. Median PFS was 9.53 months with the the enzalutamide-based combination compared with 8.28 months in those treated with placebo […]
Self-healing materials for robotics made from ‘jelly’ and salt
Researchers have developed self-healing, biodegradable, 3D-printed materials that could be used in the development of realistic artificial hands and other soft robotics applications. The low-cost jelly-like materials, developed by researchers at the University of Cambridge, can sense strain, temperature and humidity. And unlike earlier self-healing robots, they can also partially repair themselves at room temperature. […]
Key brain mechanisms for organizing memories in time: Convergence research project integrated neurobiology with data science techniques
In a scientific first, researchers at the University of California, Irvine have discovered fundamental mechanisms by which the hippocampus region of the brain organizes memories into sequences and how this can be used to plan future behavior. The finding may be a critical early step toward understanding memory failures in cognitive disorders such as Alzheimer’s […]
Wimbledon Reaches Out To Naomi Osaka Over Media Operations
Naomi Osaka is being heard. Wimbledon organizers have “started a consultation” with the tennis star and others about media operations after she withdrew from the French Open. Osaka sparked a firestorm over her decision to skip press conferences in Paris, saying she wanted to protect her mental health in an atmosphere that can turn negative. […]
How Long Should I Meditate to See Results? Types & Benefits
According to several studies, 20 minutes of meditation a day for 45-60 days can have measurable effects on the brain—from better focus to less anxiety According to several studies, 20 minutes of meditation a day for 45-60 days can have measurable effects on the brain—from better focus and more productivity to less anxiety. Everyone reacts […]
Men with high levels of body fat may be at risk for osteoporosis
Men with high levels of body fat have lower bone density and may be more likely to break a bone than those with normal levels of body fat, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism. Most studies have shown positive or neutral effects of body fat […]
Beyond sci-fi: Manipulating liquid metals without contact: Look Ma. No hands!
In a landmark discovery, FLEET University of Wollongong (UOW) researchers have realised the non-contact manipulation of liquid metal. The metals can be controlled to move in any direction, and manipulated into unique, levitated shapes such as loops and squares by using a small voltage and a magnet. The liquid metal used is galinstan, an alloy […]
Puffy planets lose atmospheres, become super-Earths: Finding represents first detections of atmospheric loss in
Astronomers have identified two different cases of “mini-Neptune” planets that are losing their puffy atmospheres and likely transforming into super-Earths. Radiation from the planets’ stars is stripping away their atmospheres, driving hot gas to escape like steam from a pot of boiling water. “Most astronomers suspected that young, small mini-Neptunes must have evaporating atmospheres,” says […]
