SpaceX launched a fully integrated Starship launch vehicle for the first time on Thursday morning, a long-awaited and highly anticipated milestone in the vehicle development program.

The orbital test flight surpassed many expectations. The vehicle cleared Max Q – the point at which the most aerodynamic pressure is exerted on the vehicle – and flew for nearly three minutes despite eight of its 33 rocket engines failing. The rocket reached an altitude of almost 40 kilometers, the point of stage separation, at which time the upper stage failed to separate from the booster, leading to uncontrolled tumbling and a spectacular midair explosion.

Despite its fiery fate, the test was a success: SpaceX got tons of valuable data that will inform future Starship and Super Heavy prototypes. But for all the wins, the test was a stark reminder that Starship mission timelines are in need of a reset.

Using an organ from a donor who underwent cardiac death, Stanford Medicine surgeons transplanted a heart while it was beating—the first time such a procedure has been achieved.

Initially performed by Joseph Woo, MD, professor and chair of cardiothoracic surgery, and his team in October, the technique has since been used in adult and five more times by surgeons at Stanford Medicine.

Stopping the heart before implantation can damage the cardiac tissue, so keeping it beating during transplantation avoids further injury to the organ.

Wake Forest Institute for Regenerative Medicine (WFIRM) scientists have created a promising injectable cell therapy to treat osteoarthritis that both reduces inflammation and also regenerates articular cartilage.

Recently identified by the Food and Drug Administration as a public health crisis, osteoarthritis affects more than 520 million people worldwide who deal with pain and . Osteoarthritis is typically induced by mechanical or traumatic stress in the joint, leading to damaged that cannot be repaired naturally.

“Without better understanding of what drives the initiation and progression of osteoarthritis, effective treatment has been limited,” said lead author Johanna Bolander of WFIRM. “Initially, we studied what goes wrong in osteoarthritic joints, compared these processes to functional environments, and used this information to develop an immunotherapy cell treatment.”

The field of plate tectonics is relatively new, and researchers are still uncovering the intricacies of geologic faults that cause earthquakes. One such fault, the Cascadia Subduction Zone, is a potentially catastrophic offshore fault located in the Pacific Northwest that has yet to reveal all its secrets. Despite its eerie calmness, it is capable of producing a massive magnitude-9 quake.

A study led by the University of Washington discovered seeps of warm, chemically distinct liquid shooting up from the seafloor about 50 miles off Newport, Oregon. Their research, published in the journal Science Advances.

<em>Science Advances</em> is a peer-reviewed, open-access scientific journal that is published by the American Association for the Advancement of Science (AAAS). It was launched in 2015 and covers a wide range of topics in the natural sciences, including biology, chemistry, earth and environmental sciences, materials science, and physics.

Scientists have analyzed the brightest gamma-ray burst (GRB) ever detected, named the BOAT (Brightest Of All Time) and GRB 221009A, which was observed by NASA

Established in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is “To discover and expand knowledge for the benefit of humanity.” Its core values are “safety, integrity, teamwork, excellence, and inclusion.” NASA conducts research, develops technology and launches missions to explore and study Earth, the solar system, and the universe beyond. It also works to advance the state of knowledge in a wide range of scientific fields, including Earth and space science, planetary science, astrophysics, and heliophysics, and it collaborates with private companies and international partners to achieve its goals.

Researchers at The University of Manchester have discovered record-high magnetoresistance in graphene.

Graphene is an allotrope of carbon in the form of a single layer of atoms in a two-dimensional hexagonal lattice in which one atom forms each vertex. It is the basic structural element of other allotropes of carbon, including graphite, charcoal, carbon nanotubes, and fullerenes. In proportion to its thickness, it is about 100 times stronger than the strongest steel.
