Government seeks Facebook help to wiretap Messenger — sources

Posted by in categories: encryption, government, law enforcement, surveillance

SAN FRANCISCO (Reuters) — The U.S. government is trying to force Facebook Inc ( FB.O ) to break the encryption in its popular Messenger app so law enforcement may listen to a suspect’s voice conversations in a criminal probe, three people briefed on the case said, resurrecting the issue of whether companies can be compelled to alter their products to enable surveillance.

The previously unreported case in a federal court in California is proceeding under seal, so no filings are publicly available, but the three people told Reuters that Facebook is contesting the U.S. Department of Justice’s demand.

The judge in the Messenger case heard arguments on Tuesday on a government motion to hold Facebook in contempt of court for refusing to carry out the surveillance request, according to the sources, who spoke on condition of anonymity.

The Dark Secret These Corporations Are Hiding From You

This is a must watch video. It tells a painful truth of our real world. It is worth the watch. Please pass this video along if you are so inclined.


Excerpt: You live in a world of drug dealers. Only the drugs can be bought legally, and are perfectly priced to prevent you from inquiring into other areas. Your society exhibits a wealth of negative side effects from these drugs. Yet the bulk of your population still continues to use our products, even after they’ve shown themselves to be harmful. You live in a population that continues to grow more restless, agitated, and depressed, in part from eating our goodies and treats. Treats that are called “superstimuli” as the stimulus it produces inside your brain vastly exceeds the natural stimuli humans received throughout evolution, from natural foods.

Steven A. Garan — Silicon Valley’s Role in Fighting Aging

Posted by in categories: biotech/medical, life extension

Today, we would like to share the talk that Steven A. Garan gave at our recent conference in New York, Ending Age-Related Diseases: Investment Prospects & Advances in Research. The conference focused on bringing together the world of research and investment and bringing thought leaders, investors, the media, and the general public together.

Steven A. Garan is the Director of Bioinformatics at the Center for Research and Education on Aging (CREA) and a researcher at UC Berkeley National Laboratory. In his talk at Ending Age-Related Diseases, he discussed the impact of various present and future Silicon Valley technology breakthroughs on overcoming aging.

The Universe’s Oldest Galaxies Could Be Right in the Milky Way’s Backyard

Posted by in category: cosmology

The Universe’s earliest epochs appear to be written into the small dwarf galaxies orbiting our own galactic home, the Milky Way.

A team of researchers studying dark matter noticed a strange trend in the brightness of the satellite galaxies around the Milky Way. There seem to be two classes of these orbiting dwarf galaxies—dim ones and bright ones—with few in the middle range. The researchers propose that this kink, when viewed on a graph, could be explained by a period early on in the Universe’s history called the re-ionization era.

Another way for stellar-mass black holes to grow larger

Posted by in categories: cosmology, physics

A trio of researchers with The University of Hong Kong, Academia Sinica Institute of Astronomy and Astrophysics in Taiwan and Northwestern University in the U.S., has come up with an alternative theory to explain how some stellar-mass black holes can grow bigger than others. In their paper published in The Astrophysical Journal Letters, Shu-Xu Yi, K.S. Cheng and Ronald Taam describe their theory and how it might work.

Since the initial detection of gravitational waves three years ago, five more detections have been observed—and five of the total have been traced back to emissions created by two stellar-mass black holes merging. The sixth was attributed to neutron stars merging. As part of their studies of such detections, space researchers have been surprised by the size of the stellar-mass black holes producing the gravity waves—they were bigger than other stellar-mass black holes. Their larger size has thus far been explained by the that they grew larger because they began their lives as stars that contained very small amounts of metal—stars with traces of metals would retain most of their mass because they produce weaker solar winds. In this new effort, the researchers suggest another possible way for stellar-mass black holes to grow larger than normal.

The new theory starts out by noting that some at the hearts of galaxies are surrounded by a disk of gas and dust. In such galaxies, there are often stars lying just outside the disk—stars that could evolve to become stellar-mass black holes. The researchers suggest that it is possible that sometimes, pairs of these stars wind up in the disk as they evolve into black holes. Such stellar-mass black holes would pull in material from the disk, causing them to grow larger. The researchers note that if such a scenario were to play out, it is also possible that the two merging could wind up with a synchronized spin resulting in a stellar-mass black hole that produces more gravity waves than if the spins had not been synchronized, making them easier for researchers to spot.

Bioengineers borrow from electronics industry to get stem cells to shape up

Posted by in categories: bioengineering, biotech/medical, life extension, robotics/AI

To understand how cells in the body behave, bioengineers create miniature models of the cells’ environment in their lab. But recreating this niche environment is incredibly complex in a controlled setting, because researchers are still learning all the factors that influence cell behavior and growth. By observing and then modifying their engineered mini-models, scientists are better able to identify those factors.

This form of cellular research is essential to the study of regenerative medicine, which focuses on replacing or repairing damaged tissue, often through the use of , a special population of that can give rise to all tissues in the body. Bioengineers face the central question of regenerative medicine: what causes stem cells to grow, organize, and mature from a small population of cells to complex organs?

To find an answer, a research team from the Johns Hopkins Institute for NanoBioTechnology borrowed a process commonly used in the electronics industry called micropatterning, in which the miniaturization of shapes increases the number of transistors on a circuit. The team created micropatterned shapes, coupled with machine learning, to see how confinement influences stem cell maturation and organization.
