Starlink is One Among Many LEO Constellations Affected by Satellite Signal Jamming

Posted by in categories: cybercrime/malcode, Elon Musk, internet, satellites

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.”

Critical cancer drug shortage forces doctors, patients to make tough choices

Posted by in categories: biotech/medical, health

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 launches Indonesian telecommunications satellite

Posted by in categories: government, satellites

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.

New Research Shows HIV Can Lie Dormant in the Brain

Posted by in categories: biotech/medical, neuroscience

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.

3D-printed “superalloy” could make power plants more efficient

Posted by in categories: energy, materials

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.

Researchers develop new device that transforms vibrations into electricity for self-powered sensors

Posted by in categories: energy, sustainability

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 .

Researchers invent low-temperature synthesis method for high-quality tellurium nanomesh for next-generation electronics

Posted by in categories: energy, nanotechnology

A collaborative team led by researchers from City University of Hong Kong (CityU) recently invented an innovative method for synthesizing high-quality, semiconducting nanomesh at a lower temperature and production cost than conventional methods. The findings will help enable the large-scale production of nanomesh for next-generation electronics.

Nanomesh is a nano-scale material formed from a network of nanowires. For several decades, one-dimensional materials like nanowires made of crystalline inorganic materials have been widely explored as the main driver for emerging electronics, as they have features like mechanical flexibility, energy efficiency and optical transparency. However, the scalability, integrability and cost-effectiveness of nanowire semiconductors are insufficient, limiting their potential for large-area electronic and optoelectronic applications.

To overcome these shortcomings, a research team led by CityU scientists made a breakthrough, inventing a low-temperature vapor-phase growth method, which can achieve large-scale synthesis of semiconducting tellurium (Te) nanomesh for use in devices.
