Third party data collection — whatever the motivation — has the potential to blur the lines between data privacy and complete identification.

In March 2020, it was revealed that the Zoom iOS app was sending user data to Facebook unbeknownst to the user. The transaction conspired in a manner where Zoom had implemented the ‘login from Facebook’ button on its iOS app, subsequently involving the Facebook Software Development Kit (SDK) in its iOS platform. The implementation of this feature allowed Facebook to access and extract users’ data from Zoom’s platform. Zoom apologised for this incident, claiming that it did not know of such implications while developing the app, further stating that it had rectified its mistake and fixed the app to remove the Facebook SDK.

Researchers at Nanyang Technological University in Singapore have developed a new type of adhesive that could lead to a different form of 3D printing.

Magnetocuring

The new process, called “magnetocuring”, overcomes several problems associated with existing export adhesives. Typical adhesives we see today involve mixing two chemicals, or exposure to heat, light or air.

Venezuela’s government is planning to move to a fully digital economy as hyperinflation has made worthless bolivar notes practically disappear, and dollarization expands through the local financial system.

The U.S. dollar has operated as an escape valve for Venezuela amid U.S. sanctions and collapsing oil revenues, President Nicolas Maduro said in a televised interview with Telesur on Friday. He said 18.6% of all commercial transactions are in dollars, while 77.3% are carried out in bolivars with debit cards. Only 3.4% are paid with bolivar notes.

“They have a war against our physical currency. We are moving this year to a more profound digital economy, in expansion. I’ve set the goal of an economy that’s 100% digital,” Maduro said, adding that physical money will eventually disappear.

Discovery of liquid glass sheds light on the old scientific problem of the glass transition: An interdisciplinary team of researchers from the University of Konstanz has uncovered a new state of matter, liquid glass, with previously unknown structural elements—new insights into the nature of glass and its transitions.

While glass is a truly ubiquitous material that we use on a daily basis, it also represents a major scientific conundrum. Contrary to what one might expect, the true nature of glass remains something of a mystery, with scientific inquiry into its chemical and physical properties still underway. In chemistry and physics, the term glass itself is a mutable concept: It includes the substance we know as window glass, but it may also refer to a range of other materials with properties that can be explained by reference to glass-like behavior, including, for instance, metals, plastics, proteins, and even biological cells.

While it may give the impression, glass is anything but conventionally solid. Typically, when a material transitions from a liquid to a the molecules line up to form a crystal pattern. In glass, this does not happen. Instead, the molecules are effectively frozen in place before crystallization happens. This strange and disordered state is characteristic of glasses across different systems and scientists are still trying to understand how exactly this metastable state forms.

By Hubble Resembles Reputed “Planet Nine” in Our Solar System.

Astronomers confirm bound orbit for planet far from its star, showing that far-flung planets exist.

Astronomers are still searching for a hypothetical “Planet Nine” in the distant reaches of our solar system, but an exoplanet 336 light years from Earth is looking more and more like the Planet Nine of its star system.

Planet Nine, potentially 10 times the size of Earth and orbiting far beyond Neptune in a highly eccentric orbit about the sun, was proposed in 2012 to explain perturbations in the orbits of dwarf planets just beyond Neptune’s orbit, so-called detached Kuiper Belt objects. It has yet to be found, if it exists.

Brown fat is that magical tissue that you would want more of. Unlike white fat, which stores calories, brown fat burns energy and scientists hope it may hold the key to new obesity treatments. But it has long been unclear whether people with ample brown fat truly enjoy better health. For one thing, it has been hard to even identify such individuals since brown fat is hidden deep inside the body.

Now, a new study in Nature Medicine offers strong evidence: among over 52000 participants, those who had detectable were less likely than their peers to suffer cardiac and metabolic conditions ranging from type 2 diabetes to , which is the leading cause of death in the United States.

The study, by far the largest of its kind in humans, confirms and expands the health benefits of brown fat suggested by previous studies. “For the first time, it reveals a link to lower risk of certain conditions,” says Paul Cohen, the Albert Resnick, M.D., Assistant Professor and senior attending physician at The Rockefeller University Hospital. “These findings make us more confident about the potential of targeting brown fat for therapeutic benefit.”
