The JADES Deep Field uses observations taken by NASA’s James Webb Space Telescope (JWST) as part of the JADES (JWST Advanced Deep Extragalactic Survey) program. A team of astronomers studying JADES data identified about 80 objects (circled in green) that changed in brightness over time. Most of these objects, known as transients, are the result of exploding stars or supernovae. Credit: NASA, ESA, CSA, STScI, JADES Collaboration.

Peering deeply into the cosmos, NASA’s James Webb Space Telescope is providing scientists with their first detailed glimpse of supernovae from a time when our universe was just a small fraction of its current age. A team using Webb data has identified 10 times more supernovae in the early universe than were previously known. A few of the newfound exploding stars are the most distant examples of their type, including those used to measure the universe’s expansion rate.

A new study confirmed that a 3500-year-old Mycenaean suit of armor was combat-ready, as evidenced by tests with Greek Marines enduring a rigorous combat simulation, highlighting its significant role in Mycenaean military prowess.

A study recently published in the open-access journal PLOS ONE reveals that a famous Mycenaean suit of armor was designed for extended combat, not just for ceremonial purposes. The research, conducted by Andreas Flouris and colleagues at the University of Thessaly in Greece, supports its use in active warfare.

One of the oldest known suits of European armor is a 3500-year-old suit found near the village of Dendra, a few kilometers away from ancient Mycenae. Since its discovery in 1960, it has been unclear if this was a ceremonial suit or if it was suitable for battle. This question has important implications for understanding warfare in Late Bronze Age Europe, but no historical accounts describe the use of this style of armor. In this study, researchers combine historical and experimental evidence to investigate the combat suitability of the Dendra armor.

1. Privacy is important, but not always guaranteed. Grantcharov realized very quickly that the only way to get surgeons to use the black box was to make them feel protected from possible repercussions. He has designed the system to record actions but hide the identities of both patients and staff, even deleting all recordings within 30 days. His idea is that no individual should be punished for making a mistake.

The black boxes render each person in the recording anonymous; an algorithm distorts people’s voices and blurs out their faces, transforming them into shadowy, noir-like figures. So even if you know what happened, you can’t use it against an individual.

But this process is not perfect. Before 30-day-old recordings are automatically deleted, hospital administrators can still see the operating room number, the time of the operation, and the patient’s medical record number, so even if personnel are technically de-identified, they aren’t truly anonymous. The result is a sense that “Big Brother is watching,” says Christopher Mantyh, vice chair of clinical operations at Duke University Hospital, which has black boxes in seven operating rooms.

When a magnet is heated up, it reaches a critical point where it loses magnetization.

The Tesla chief executive had claimed that the A.I. start-up put profits and commercial interests ahead of benefiting humanity.

Currently, so-called “oncolytic viruses” such as herpes are used to treat some types of cancer because of their ability to kill cancer cells. But these therapies are not effective with some tumors and their use poses safety concerns, especially in immunosuppressed patients, underscoring the need for safer alternatives, Penaloza-MacMaster said.

In addition to helping clear the tumors, the therapy also helped prevent future cancer in these mice. Healthy mice that were first treated with the LCMV therapy were more resistant to developing tumors later in life.

This phenomenon might be explained by a poorly understood biological process known as “trained immunity.” Trained immunity occurs when a previous infection enhances the immune system’s ability to respond to different diseases in the future. For example, studies have shown that children who received the tuberculosis (TB) vaccine exhibit improved protection against other microorganisms, not just TB. This differs from the typical vaccine response, such as with the SARS-CoV-2 vaccine, which primarily protects against this specific virus.

Astronomers are expecting a “new star” to appear in the night sky anytime between now and September in a celestial event that has been years in the making, according to NASA.

“It’s a once-in-a-lifetime event that will create a lot of new astronomers out there, giving young people a cosmic event they can observe for themselves, ask their own questions, and collect their own data,” said Dr. Rebekah Hounsell, an assistant research scientist specializing in nova events at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, in a statement. “It’ll fuel the next generation of scientists.”

The expected brightening event, known as a nova, will occur in the Milky Way’s Corona Borealis, or Northern Crown constellation, which is located between the Boötes and Hercules constellations.
