After Russian hackers destroyed Viasat satellite ground receivers spanning Europe, SpaceX provided coverage via Starlink, its Lower Earth Orbit satellite constellation, and soon began noticing cyberattacks and software interferences. Now, a year later, the U.S. Department of Defense announced Russia is still attempting to complicate connections within the satellite constellation and others like it.

Documents were leaked by U.S. National Guard airman Ryan Teixeira, as reported by The Washington Post back in April of 2023. Ukraine has also stated it is experiencing similar security issues.

“Russia’s quest to sabotage Ukrainian forces’ internet access by targeting the Starlink satellite operations that billionaire Elon Musk has provided to Kyiv since the war’s earliest days appear to be more advanced than previously known, according to a classified U.S. intelligence report.”

“I’d like to emphasize that these are neither embryos, nor are we trying to make embryos actually,” Dr. Jitesh Neupane, of the University of Cambridge’s Gurdon Institute, said.

According to a recent tweet from Twitter owner Elon Musk who recently confirmed the app, Twitter is preparing to launch its own video app for Smart TVs.

Hospitals and cancer centers are running out of two major injectable cancer drugs: carboplatin and cisplatin. Dr. Eleonora Teplinsky, head of breast medical oncology for the Valley Health System in New Jersey, joins Ali Rogin to discuss the causes and effects of the shortages, and the dilemmas that providers and their patients now face.

SpaceX’s Falcon 9 carrying the PSN Satria satellite successfully launched and deployed at 6:21 PM ET (22:21 UTC).

The launch had a 178-minute window, and upper-level winds delayed the first launch attempt at the opening of the window, but SpaceX had plenty of time to work with and launched just a bit later into the launch window.

The PSN Satria Indonesian Telecommunications was first contracted to be built in 2020 by Thales Alenia Spaceby the Indonesian government and delivered to the launch site in Cape Canaveral, Florida, in May 2023.

Scientists from the HIV Cure Center at the UNC School of Medicine, University of California San Diego, Emory University, and University of Pennsylvania have been searching for where exactly these latent cells are hiding in the body. New research published in the Journal of Clinical Investigations confirms that microglial cells – which are specialized immune cells with a decade-long lifespan in the brain – can serve as a stable viral reservoir for latent HIV.

Yuyang Tang, PhD, and Guochun Jiang, PhD, in the UNC School of Medicine extracted living brain tissue to conclude that specialized immune cells in the brain can harbor latent but replication-competent HIV.

As a part of its life cycle, the human immunodeficiency virus-1 (HIV) inserts a copy of its DNA into human immune cells. Some of these newly infected immune cells can then transition into a dormant, latent state for a long period of time, which is referred to as HIV latency.

There were at least eight other human species, some of whom existed for far longer than we have. Who were they?

A new high-performance metal alloy, called a superalloy, could help boost the efficiency of the turbines used in power plants and the aerospace and automotive industries.

Created using a 3D printer, the superalloy is composed of a blend of six elements that altogether form a material that’s both lighter and stronger than the standard materials used in conventional turbine machinery. The strong superalloy could help industries cut both costs and carbon emissions — if the approach can be successfully scaled up.

The challenge: In the world of materials science, the search for new metal alloys has been heating up in recent years. For over a century, we’ve depended on relatively simple alloys like steel, composed of 98% iron, to form the backbone of our manufacturing and construction industries. But today’s challenges demand more: alloys that can withstand higher temperatures and remain strong under stress, yet still be lightweight.

An international research group has engineered a new energy-generating device by combining piezoelectric composites with carbon fiber-reinforced polymer (CFRP), a commonly used material that is both light and strong. The new device transforms vibrations from the surrounding environment into electricity, providing an efficient and reliable means for self-powered sensors.

Details of the group’s research were published in the journal Nano Energy on June 13, 2023.

Energy harvesting involves converting energy from the environment into usable electrical energy and is something crucial for ensuring a sustainable future.
