Rocket Launch to Image Supernova Remnant

Cassiopeia A

A Northwestern University astrophysics team is aiming for the stars—well, a dead star, that is.

On Aug. 21, the NASA-funded team will launch its “Micro-X” rocket from White Sands Missile Range in southern New Mexico. The rocket will spend 15 minutes in space—just enough time to snap a quick image of supernova remnant Cassiopeia A, a star in the Cassiopeia constellation that exploded approximately 11,000 light-years away from Earth. Then, the rocket will parachute back to Earth, landing in the desert—about 45 miles from the launchpad—where the Northwestern team will recover its payload.

Short for “high-resolution microcalorimeter Xray imaging rocket,” the Micro-X rocket will carry a superconductor-based X-ray imaging spectrometer that is capable of measuring t...

Bioengineered Cornea Restores Sight to the Blind and Visually Impaired

Researchers and entrepreneurs have developed an implant made of collagen protein from pig’s skin, which resembles the human cornea. In a pilot study, the implant restored vision to 20 people with diseased corneas, most of whom were blind prior to receiving the implant. The study jointly led by researchers at Linköping University (LiU) and LinkoCare Life Sciences AB has been published in Nature Biotechnology. The promising results bring hope to those suffering from corneal blindness and low vision by providing a bioengineered implant as an alternative to the transplantation of donated human corneas, which are scarce in countries where the need for them is greatest.

“The results show...

Stars Determine their Own Masses

Simulation of a star-forming region, where massive stars destroy their parent cloud.

Simulations show why stars formed in different environments form similar masses. Last year, a team of astrophysicists including key members from Northwestern University launched STARFORGE, a project that produces the most realistic, highest-resolution 3D simulations of star formation to date. Now, the scientists have used the highly detailed simulations to uncover what determines the masses of stars, a mystery that has captivated astrophysicists for decades.

In a new study, the team discovered that star formation is a self-regulatory process. In other words, stars themselves set their own masses. This helps explain why stars formed in disparate environments still have similar masses...

Research Discovery may Help Diagnose and Treat Cancer and Brain Disorders

Cancer diagnosis pathways image

Researchers at Queen’s University Belfast discovered how the journey or molecular pathway of an identified protein is both essential for brain development and how an alteration to its pathway could result in the spread of cancer.

The study, published today in Nature Cell Biology, has revealed the molecular mechanisms of a timely and spatially controlled movement of cells that is essential for the migration of newborn neurons during brain development and can also cause the spread of cancer, or cancer metastasis throughout the body.

It is expected this discovery will have a huge impact on the fundamental understanding of cancer metastasis and brain development and could lead to earlier diagnosis and better treatments, the research authors said.

During brain development, neural ...
