Out in the wider world, patients usually go to their doctors because they have a lump that they can see or feel. It might be under their jaw, on their cheek or behind their ear.

But here at MD Anderson, most cases of salivary gland cancer are found incidentally, because our patients are getting CT scans for some other reason.

Salivary gland cancer almost never has symptoms, but the high-grade aggressive types can get big fast. Since they’re occurring in a confined space, there may be some discomfort associated with the growing mass. Someone’s ear might feel full, for example, or their jaw might feel tight. But the mass itself is not usually painful.

Cybersecurity researchers have found a way to exploit a recently disclosed critical flaw in PaperCut servers in a manner that bypasses all current detections.

Tracked as CVE-2023–27350 (CVSS score: 9.8), the issue affects PaperCut MF and NG installations that could be exploited by an unauthenticated attacker to execute arbitrary code with SYSTEM privileges.

While the flaw was patched by the Australian company on March 8, 2023, the first signs of active exploitation emerged on April 13, 2023.

August will see the second annual Longevity Summit take place in Dublin. Packed with keynote presentations by leading experts in the aging field, the summit will showcase some of the latest – and most exciting – research and innovations in the longevity space.

Longevity. Technology: One of the Longevity Summit’s most-anticipated speakers is eminent gerontologist Dr Aubrey de Grey. Since the launch of the Longevity Escape Velocity Foundation, which Dr de Grey announced at Dublin last year, news on progress of its flagship research programme Robust Mouse Rejuvenation has been keenly awaited, as has further details on its research into transplants on demand.

Earlier this week, we caught up with Dr de Grey to find out more about the conference, its speakers and agenda, and today we dig into what he and LEV Foundation have been up to.

PacWest Bancorp said late on Wednesday it was in talks with potential partners and investors about strategic options after shares of the Los Angeles-based lender and several other U.S. regional banks tumbled amid fears of a worsening banking crisis.

Peter Morici, professor emeritus at the University of Maryland, joined NewsNation Now to discuss.

We’re hearing this week from two very different parts of the string theory community that quantum supremacy (quantum computers doing better than classical computers) is the answer to the challenges the subject has faced.

New Scientist has an article Quantum computers could simulate a black hole in the next decade which tells us that “Understanding the interactions between quantum physics and gravity within a black hole is one of the thorniest problems in physics, but quantum computers could soon offer an answer.” The article is about this preprint from Juan Maldacena which discusses numerical simulations in a version of the BFSS matrix model, a 1996 proposal for a definition of M-theory that never worked out. Maldacena points to this recent Monte-Carlo calculation, which claims to get results consistent with expectations from duality with supergravity.

Maldacena’s proposal is basically for a variant of the wormhole publicity stunt: he argues that if you have a large enough quantum computer, you can do a better calculation than the recent Monte-Carlo. In principle you could look for quasi-normal modes in the data, and then you would have created not a wormhole but a black hole and be doing “quantum gravity in the laboratory”.

A few hours ago, the Fuego volcano erupted in Guatemala.
An orange alert has been declared.
The eruption resulted in the formation of ash columns over 5 km high.
Lava flows began to descend from the crater.
Abundant volcanic ash fell on nearby villages.
The evacuation of residents and the blocking of roads begins.
It is expected that the activity of the volcano will continue for at least another 24 hours.
Fuego is one of the most active volcanoes in the country.
It is located 40 km from the capital of Guatemala.
