“In recent years, the clinical development of liquid biopsies for cancer, a revolutionary screening tool, has created great optimism,” write Liz Kwo and Jenna Aronson in the American Journal of Managed Care.

At present, liquid biopsies can detect more than 50 different types of cancer. A standard visit to the doctor may eventually be able to detect cancers years before they become lethal.

In the future, even the toilet in your bathroom may be sensitive enough to detect the signs of cancer cells, enzymes and genes circulating in your bodily fluids, so that cancer becomes no more lethal than the common cold. Every time you go to the bathroom, you might be tested for cancer. The “smart toilet” might become our first line of defense.

Researchers develop artificial ‘power plants’ in the form of tiny leaf-shapes to harness energy from the wind and rain.

The US and China are racing to be the first to put a man on the moon in the 21st Century, but NASA last week announced delays to its crewed missions.

Silicon-based complementary metal-oxide semiconductors or negative differential resistance device circuits can emulate neural features, yet are complicated to fabricate and not biocompatible. Here, the authors report an ion-modulated antiambipolarity in mixed ion–electron conducting polymers demonstrating capability of sensing, spiking, emulating the most critical biological neural features, and stimulating biological nerves in vivo.

Researchers have identified the oldest black hole ever observed, dating from the beginning of the universe, and determined that it is ‘eating’ its host galaxy to death. The study, published in the journal Nature, used the James Webb Space Telescope (JWST) to locate the black hole, which formed 400 million years after the Big Bang, more than 13 billion years ago.

Researchers using the James Webb Space Telescope have uncovered the oldest black hole ever detected—and declared a new era in astronomy.

It was found at the center of GN-z11, a galaxy first discovered in 2017, about 13.4 billion light-years away from our Milky Way galaxy—but about 100 times smaller. That means it exists just 400 million years after the Big Bang, which is thought to have created the universe. However, the black hole looks to be about a billion years old, suggesting problems with theories about how quickly black holes form.

The discovery, announced in a paper published today in the journal Nature, is the result of the sensitivity of JWST, which can see deep into the infrared, detecting old light that has been traveling across deep since the dawn of time.

Researchers have discovered the oldest black hole ever observed, dating from the dawn of the universe, and found that it is ‘eating’ its host galaxy to death.

The international team, led by the University of Cambridge, used the NASA/ESA/CSA James Webb Space Telescope (JWST) to detect the black hole, which dates from 400 million years after the Big Bang, more than 13 billion years ago. The results, which lead author Professor Roberto Maiolino says are “a giant leap forward,” are reported in the journal Nature.

That this surprisingly massive black hole —a few million times the mass of our sun—even exists so early in the universe challenges our assumptions about how black holes form and grow. Astronomers believe that the supermassive black holes found at the center of galaxies like the Milky Way grew to their current size over billions of years. But the size of this newly-discovered black hole suggests that they might form in other ways: they might be ‘born big’ or they can eat matter at a rate that’s five times higher than had been thought possible.

Like it or not, humans are becoming as gods. Where will this trend lead?How about the ability to bring back to life people who died years, decades, or centur…

6D Heterotic Little String Theories(LSTs) are a subsector of every 6D SUGRA (with at least one tensor multiplet), after decoupling gravity. As such, while possessing usual QFT-like properties such as global symmetries, they also possess gravity-like properties such as T-duality, which makes them an interesting intermediate. Recently, a fruitful line of research has been to chart the landscape of T-dual LSTs, and establish certain invariants across this T-duality, which includes the 5D Coulomb branch dimension, and the 2-Group structure constants (mixed anomalies). In this talk, we will argue that the rank of the flavor algebra is another invariant across this duality. This involves using 6D anomaly cancellation conditions and carefully taking into account potential ABJ anomalies. We will then discuss some interesting novel LSTs with non-trivial flavor holonomies, focusing on their T-duality structure. Based on arXiv:2311.02168.
