Squeezing Oscillations in a Multimode Bosonic Josephson Junction

We use two 1D quasicondensates in a double potential well to realize a bosonic Josephson junction, a microscopic system that gives rise to interesting quantum phenomena resulting from the interplay of quantum tunneling and interaction. The multimode characteristics within the quasicondensates make the system suitable as a quantum field simulator. To prepare quantum states, we split a single condensate into two and, consequently, we witness the dynamical evolution of quantum fluctuations in the relative degree of freedom between the two split condensates. We demonstrate how to use these dynamics to effectively prepare more strongly correlated quantum states and how those influence spatial phase coherence.

Our work introduces innovative methods for engineering correlations and entanglement in the external degree of freedom of interacting many-body systems. It is a leap forward in understanding and harnessing quantum correlations, paving the way for exciting possibilities in quantum simulation research.

Incredible cancer breakthrough sees woman’s brain tumor almost disappear in just five days

They treated three patients with recurrent glioblastoma using a variant of an existing CAR-T therapy, adding additional antibodies to the treatment — and the results were truly astounding.

According to the paper published in The New England Journal of Medicine, one patient saw their tumor decrease in size by 18.5% two days after the treatment, and by day 69, the tumor had decreased by 60.7%, while another saw their ‘tumor regress rapidly’, according to Mass General Brigham.

After the third patient was treated, an MRI showed that a single infusion had led to a ‘near-complete tumor regression’ in just five days.

Dark matter doesn’t exist and the universe is 27 billion years old • Earth

The fabric of the cosmos, as we currently understand it, comprises three primary components: ‘normal matter,’ ‘dark energy,’ and ‘dark matter.’ However, new research is turning this established model on its head.

A recent study conducted by the University of Ottawa presents compelling evidence that challenges the traditional model of the universe, suggesting that there may not be a place for dark matter within it.

Dark matter, a term used in cosmology, refers to the elusive substance that does not interact with light or electromagnetic fields and is only identifiable through its gravitational effects.

Engineering the Microbiome: CRISPR Leads the Way

Scientists have categorized different types of CRISPR systems into two classes based on how their Cas nucleases function. In class 1 (types I, III, and IV), different Cas proteins form a complex machinery to identify and cut foreign DNA; in class 2 CRISPR systems (types II, V, and VI), a single Cas protein effector recognizes and cleaves DNA.9

After characterizing CRISPR’s role as a defense mechanism in bacteria, researchers soon realized that they could harness this system for gene manipulation in any cell. All they needed to do was design a CRISPR gRNA sequence that bound to a specific DNA sequence and triggered the Cas nuclease, which would then cut precisely at that location. With CRISPR, researchers routinely knock out gene function by cutting out a DNA fragment, or they insert a desired genetic sequence into the genome by providing a reference DNA template along with the CRISPR components. While editing eukaryotic cells has been the focus for tackling diseases, many researchers now use CRISPR to edit bacterial communities.

“It’s almost like back to the beginning or back to the origins. There’s some irony in bringing CRISPR back to where it came from,” said Rodolphe Barrangou, a functional genomics researcher at North Carolina State University, who helped characterize the immune function of CRISPR and has been working with it for more than 20 years.

China is beating the U.S. on self-driving cars because of one feature

Wired writer Mark Andrews tested three Chinese vehicles equipped with semi-autonomous functionality and found them superior to comparable American self-driving systems. The reasons, it seems, boil down to a single feature that American passenger cars have yet to implement: Lidar. From Wired:

On the flip side, Tesla and General Motors have been grabbing most of the recent headlines when it comes to self-driving cars in the hands of the public, and for all the wrong reasons—mass recalls, suspended licenses, spending cuts, and huge losses.

But in China, a number of companies are steadily—and far more successfully—moving toward a similar destination, but via a different route.
