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:

A preclinical trial demonstrated that gene therapy could dissolve the nerve-blocking scars that form after spinal cord damage in lab rats.

Some worms that inhabit lakes and rivers are capable of almost limitless regeneration.

Some worms that inhabit lakes and rivers are capable of almost limitless regeneration, and scientists have isolated the cell that allows them to perform their death-defying feats.

The ability of planarian flatworms to regrow severed heads and other body parts has been known for over a century, but new techniques have allowed a research team to discover how they do it.

Why is no one talking about this? — “More than one-third of U.S. adults are taking prescription medications that may lead to depression, new research finds. The study, published in the Journal of the American Medical Association, warns that depression is a potential side effect of more than 200 commonly prescribed medications, including beta blockers for blood pressure, birth control pills, antacids, and painkillers.”

___ Many Americans taking common meds that may cause depression, study finds (CBS News): “More than one-third of U.S. adults are taking prescription medications that may lead to depression, new research finds. The study, published in the Journal of the American Medical Association, warns that depression is a potential.

It’s been seven years since astronauts launched into space from U.S. soil.

From idolized to anonymous, what it means to be an American astronaut is changing once more.

Collider will be far more sensitive to anomalies that could lead to entirely new theories of the universe.

A spacecraft, spinning in Earth’s orbit, reaches inside itself. One of its four arms pulls out a length of polymer pipe that has been 3D-printed inside the body of the machines. All four of the spacecraft’s arms are securing pieces together as it builds a new space station right there in orbit.

This surreal project, called Archinaut, is the future vision of space manufacturing company Made In Space. The company promises a future of large imaging arrays, kilometer-scale communications tools, and big space stations all built off-planet by smart robots.

In case we needed more evidence that staying fit is good for you…

A study to be published in the Journal of Alzheimer’s Disease shows a correlation between low fitness, aortic stiffness, and the cognitive decline typically observed during brain aging [1].

Deep-seated fears, like the memory of a death or war-time trauma, can be crippling. They’re also notoriously hard to study and treat, says neuroscientist Ossama Khalaf, Ph.D. But finally, we’re making progress: In a Science paper published Thursday, Khalaf and his team show new evidence suggesting that fearful memories that dwell deep in the brain’s neural circuitry don’t have to be a burden forever. It’s possible, the paper suggests, that they can be rewired.

The paper is rooted in the science of engrams — the idea that memories leave a physical trace in the brain. In this case, Khalaf, a researcher at École Polytechnique Fédérale de Lausanne, and his team traced deep-seated fear memories in rats back to the activity of specific neurons. They found that the way those neurons fire — and thus the fearful memory they encode — can be reprogrammed.

“In our study, we are providing the first experimental evidence that fear memory attenuation is mediated by the re-engagement of the original fear re-writing it towards safety,” Khalaf tells Inverse via email.
