Underground Italian lab searches for signals of quantum gravity
For decades, physicists have been hunting for a quantum-gravity model that would unify quantum physics, the laws that govern the very small, and gravity. One major obstacle has been the difficulty in testing the predictions of candidate models experimentally. But some of the models predict an effect that can be probed in the lab: a very small violation of a fundamental quantum tenet called the Pau
A Roomba recorded a woman on the toilet. How did screenshots end up on Facebook?

The photos were mundane, if sometimes intimate, household scenes captured from low angles—including some you really wouldn't want shared on the Internet. In one particularly revealing shot, a young woman in a lavender T-shirt sits on the toilet, her shorts pulled down to mid-

Male mason wasps use genital spines to thwart predators, study reveals
Wasps seen piercing the mouth or other parts of tree frogs with their sharp weapon when being attacked Kipling might well have believed that the female of the species is more deadly than the male, but when it comes to mason wasps, the latter have quite the weapon.

Deblurring can reveal 3D features of heavy-ion collisions
When the nuclei of atoms are about to collide in an experiment, their centers never perfectly align along the direction of relative motion. This leads to collisions with complex three-dimensional geometry. Emissions from the dense hot region of nuclear matter form patterns during a collision.
Measuring gamma-ray bursts' hidden energy unearths clues about the evolution of the universe
Gamma-ray bursts are the most luminous explosions in the universe, allowing astrologists to observe intense gamma rays in short durations. Gamma-ray bursts are classified as either short or long, with long gamma-ray bursts being the result of massive stars dying out. They provide hidden clues about the evolution of the universe.

A diamond-based quantum amplifier
In physics, weak microwave signals can be amplified with minimal added noise. For instance, artificial quantum systems based on superconducting circuits can amplify and detect single microwave patterns, although at millikelvin temperatures. Researchers can use natural quantum systems for low-noise microwave amplification via stimulated emission effects; however, they generate a higher noise at fun

Wearable skin patch monitors hemoglobin in deep tissues
A team of engineers has developed a photoacoustic patch that can monitor biomolecules in deep tissues, including hemoglobin. It can perform 3D mapping of hemoglobin with a submillimeter spatial resolution in deep tissues, down to centimeters below the skin, versus other wearable electrochemical devices that only sense the biomolecules on the skin surface.
High School program linked to lower substance use, better health behaviors
The AVID college prep program leads to lower substance use, better health behaviors among high school students. Significantly, the findings suggest that 'academic tracking,' the practice of separating high and low performing students into different classes, reinforces risky social networks and behaviors.
Immune surprise: Recently evolved alarm molecule drives inflammation
Scientists have made an important breakthrough in understanding how inflammation is regulated. They have just discovered that a key immune alarm protein previously believed to calm down the immune response actually does the opposite. Their work has numerous potential impacts, especially in the context of understanding and responding to autoimmune disorders and inflammation.

What's the current status of solar panel research and when can we expect more efficient and smaller panels?
It seems to me we are still using solar panels designed 20+ years ago. When are we going to use more efficient and smaller panels? I remember 10 years ago researchers created panels the size of napkins, with the same efficiency as we have today. submitted by /u/albemala [link] [comments]
