This new Picture of the Month from the NASA/ESA/CSA James Webb Space Telescope reveals intricate details of the Herbig Haro object 797 (HH797). Herbig-Haro objects are luminous regions surrounding newborn stars (known as protostars), and are formed when stellar winds or jets of gas spewing from these newborn stars form shockwaves colliding with nearby gas and dust at high speeds.

HH 797, which dominates the lower half of this image, is located close to the young open star cluster IC348, which is located near the eastern edge of the Perseus dark cloud complex. The bright infrared objects in the upper portion of the image are thought to host two further protostars.

This image was captured with Webb’s Near-InfraRed Camera (NIRCam). Infrared imaging is powerful in studying newborn stars and their outflows, because the youngest stars are invariably still embedded within the gas and dust from which they are formed. The infrared emission of the star’s outflows penetrates the obscuring gas and dust, making Herbig-Haro objects ideal for observation with Webb’s sensitive infrared instruments.

Molecular toxicology is a field that investigates the interactions between chemical or biological molecules and organisms at the molecular level. In this Special Issue, we focus on the toxic effects and mechanisms of action of chemical and biological molecules, will be of great interest of readers in molecular toxicology and applied pharmacology.

WASHINGTON — The Space Development Agency has set its sights on an ambitious launch schedule for 2024 following two successful launches this year that marked steady progress for the fledgling U.S. Space Force agency.

“Starting next September, it’s an 11-launch campaign over 11 months, one launch a month,” SDA Director Derek Tournear said Dec. 7 at a National Security Space Association online forum.

SDA is developing a network of satellites known as the Proliferated Warfighter Space Architecture — a large constellation of lower-cost, mass-produced satellites in low Earth orbit. This is different from the traditional DoD approach of using small numbers of expensive, highly-customized satellites.

Microsoft Outlook was reportedly targeted over 10,000 times this summer by a single threat actor, which is believed to be aligned with Russia.

Cybersecurity company Proofpoint recently unveiled its research announcing that a group they call TA422 (or Forest Blizzard, Pawn Storm, Fancy Bear, and BlueDelta) was seen attempting daily hacking into the same accounts. It seems that this is a continuation of an earlier campaign by TA422 against various organizations in Europe and North America. US intelligence links the group to its Russian counterpart, the GRU.

Rosacea is a skin condition that causes reddened skin and rash, usually on the nose and cheeks. There is no test for rosacea, so health care providers will typically diagnose it based on the appearance of the skin and your health history. They may run tests to rule out any other conditions.

What is rosacea? It is a long-term disease that causes reddened skin and pimples, usually on the face. It can also make the skin thicker and cause eye problems.

The medial patellofemoral ligament (MPFL) is the most important stabilizer of lateral dislocation of the patella. Single-limb (SL) and double-limb (DL) graft MPFL reconstructions have been increasingly used to treat recurrent patellar dislocations, but the clinical efficacy of SL versus DL graft MPFL reconstructions remains controversial owing to the inconsistent conclusions of previous studies.

When motoring content firm Hagerty published its video review of the Tesla Cybertruck, automotive journalist Jason Cammisa lightly noted that Tesla had sent other auto CEOs a pamphlet called “How to Design a 48-Volt Vehicle.” Cammisa seemed like he was joking in the video, so his comments were mostly taken in stride by the electric vehicle community.

But as per a recent comment from Ford CEO Jim Farley, it appears that Tesla really did send out a “How to Design a 48-Volt Vehicle” guide to other auto CEOs. In a post on X, the social media platform formerly known as Twitter, Farley noted that Tesla was definitely not joking, as Ford had received the document.

Farley also remarked that Ford had received the pamphlet on December 5, 2023. The Ford CEO actually seemed like he appreciated the document, as he thanked Elon Musk and stated that the guide would be “great for the industry.” Elon Musk, for his part, seemed to appreciate the Ford CEO’s reaction to the 48V guide. In a response on X, Musk simply noted, “You’re welcome.”

The concept of biological immortality challenges the belief that death gives meaning to life and raises questions about the potential societal implications and ethical considerations of living indefinitely.

Questions to inspire discussion.

What is biological immortality?
—Biological immortality refers to the potential for humans to live indefinitely due to advancements in science and technology, leading to the elimination of age-related diseases and the aging process.
