The Chandra X-Ray Observatory is a NASA telescope that looks at black holes, quasars, supernovas, and the like – all sources of high energy in the universe. It shows a side of the cosmos that is invisible to the human eye.

After more than a decade in service, the observatory has helped scientists glimpse the universe in action. It has watched galaxies collide, observed a black hole with cosmic hurricane winds, and glimpsed a supernova turning itself inside out after an explosion.

The telescope – billed as one of NASA’s Great Observatories along with the Hubble Space Telescope, Spitzer Space Telescope and the Compton Gamma Ray Observatory – has been a public relations tool for the agency, as well. Its pictures are frequently used by NASA in press releases.

“Horizontal gene transfer is an important way that antibiotic resistance moves between bacterial species, but the process has never been observed before, since the structures involved are so incredibly small,” said biologist Ankur Dalia of Indiana University Bloomington.

Bacteria are slippery little suckers. They evolve rapidly, developing resistance to antibiotics and therefore becoming increasingly difficult to deal with. Now, for the first time, researchers have caught on film one of the mechanisms the microbes use for this speedy evolution.

Two Vibrio cholerae bacteria — the pathogen responsible for cholera — sit under a microscope, glowing a vivid green. As we watch, a tendril snakes forth from one of the bacterium, harpooning a piece of DNA and carrying it back to its body.

Today, we want to draw your attention to an open-access review that focuses on the role of senescent cells in sarcopenia, the age-related loss of muscle mass and strength that leads to frailty.

David Eagleman, the science adviser for HBO’s TV series “Westworld,” shares his thoughts on the future of AI and whether robots will ever become conscious.

Quantum computers, once they become common, will complete difficult tasks thousands of times more quickly than current PCs. That could obviously threaten a classic chipmaker like Intel, but it plans to use its knowledge of silicon production to build quantum chips more quickly than its peers.

Yet even the U.S. is disturbingly vulnerable—and in some respects is becoming quickly more so. It depends on a just-in-time medical economy, in which stockpiles are limited and even key items are made to order. Most of the intravenous bags used in the country are manufactured in Puerto Rico, so when Hurricane Maria devastated the island last September, the bags fell in short supply. Some hospitals were forced to inject saline with syringes—and so syringe supplies started runn…ing low too. The most common lifesaving drugs all depend on long supply chains that include India and China—chains that would likely break in a severe pandemic. “Each year, the system gets leaner and leaner,” says Michael Osterholm, the director of the Center for Infectious Disease Research and Policy at the University of Minnesota. “It doesn’t take much of a hiccup anymore to challenge it.”

The epidemics of the early 21st century revealed a world unprepared, even as the risks continue to multiply. Much worse is coming.

KANSAS CITY, MO — Researchers at the Stowers Institute for Medical Research have captured the one cell that is capable of regenerating an entire organism. For over a century, scientists have witnessed the effects of this cellular marvel, which enables creatures such as the planarian flatworm to perform death-defying feats like regrowing a severed head. But until recently, they lacked the tools necessary to target and track this cell, so they could watch it in action and discover its secrets.

Now, by pioneering a technique that combines genomics, single-cell analysis, flow cytometry and imaging, scientists have isolated this amazing regenerative cell – a subtype of the long-studied adult pluripotent stem cell – before it performs its remarkable act. The findings, published in the June 14, 2018, issue of the journal Cell, will likely propel biological studies on highly regenerative organisms like planarians and also inform regenerative medicine efforts for other organisms like humans that have less regenerative capacity.

“This is the first time that an adult pluripotent stem cell has been isolated prospectively,” says Alejandro Sánchez Alvarado, Ph.D., an investigator at the Stowers Institute and Howard Hughes Medical Institute and senior author of the study. “Our finding essentially says that this is no longer an abstraction, that there truly is a cellular entity that can restore regenerative capacities to animals that have lost it and that such entity can now be purified alive and studied in detail.”

On May 20, China launched Queqiao, a lunar communications relay satellite for the upcoming Chang’e 4 lander and rover mission. On the way out to the Moon, it dropped off a pair of small satellites bound for lunar orbit called Longjiang-1 and Longjiang-2. The satellites weigh just 45 kilograms each and measure 50-by-50-by-40 centimeters. Their purpose is testing out future radio astronomy and interferometry techniques, and one also has a camera built by Saudi Arabia.

Unfortunately, Longjiang-1 had a problem and didn’t make it into lunar orbit. Longjiang-2, however, was successful, and sent home a few pictures! Check them out:
