Circa 2021 immortality of the pancreas by inducing pluripotent cells of the pancreas.
A microwell chip facilitates the single-cell characterization of the differentiation of aggregates of human induced pluripotent stem cells into pancreatic duct-like organoids and the discovery of secreted markers of pancreatic carcinogenesis.

Immortal epithelial cell lines were previously established after transduction of the HPV16-E6E7 genes into primary cultures of normal pancreatic duct epithelial cells. Single clones were isolated that demonstrated near normal genotype and phenotype. The proliferation of HPDE6-E6E7c7 and c11 cells is anchorage-dependent, and they were nontumorigenic in SCID mice. The cell lines demonstrated many phenotypes of normal pancreatic duct epithelium, including mRNA expression of carbonic anhydrase II, MUC-1, and cytokeratins 7, 8, 18, and 19.
Circa 2021 Basically this article details cannabinoids that have been successfully synthesized which can lead to even greater psychiatric medicine aswell as many of other types of uses.
Abstract Cannabis has been integral to Eurasian civilization for millennia, but a century of prohibition has limited investigation. With spreading legalization, science is pivoting to study the pharmacopeia of the cannabinoids, and a thorough understanding of their biosynthesis is required to engineer strains with specific cannabinoid profiles. This review surveys the biosynthesis and biochemistry of cannabinoids. The pathways and the enzymes’ mechanisms of action are discussed as is the non-enzymatic decarboxylation of the cannabinoic acids. There are still many gaps in our knowledge about the biosynthesis of the cannabinoids, especially for the minor components, and this review highlights the tools and approaches that will be applied to generate an improved understanding and consequent access to these potentially biomedically-relevant materials.

Powerful cosmic radio pulses originating deep in the universe can be used to study hidden pools of gas cocooning nearby galaxies, according to a new study that was published last month in the journal Nature Astronomy.
So-called fast radio bursts, or FRBs, are pulses of radio waves that typically originate millions to billions of light-years away. (Radio waves are electromagnetic radiation like the light we see with our eyes but have longer wavelengths and lower frequencies). The first FRB was discovered in 2007, and since then, hundreds more have been detected. In 2020, Caltech’s STARE2 instrument (Survey for Transient Astronomical Radio Emission 2) and Canada’s CHIME (Canadian Hydrogen Intensity Mapping Experiment) detected a massive FRB that went off in our own Milky Way galaxy. Those earlier findings helped confirm the theory that the energetic events most likely originate from dead, magnetized stars called magnetars.
As more and more FRBs roll in, scientists are now investigating how they can be used to study the gas that lies between us and the bursts. Specifically, they would like to use the FRBs to probe halos of diffuse gas that surround galaxies. As the radio pulses travel toward Earth, the gas enveloping the galaxies is expected to slow the waves down and disperse the radio frequencies. In the new study, the research team looked at a sample of 474 distant FRBs detected by CHIME, which has discovered the most FRBs to date. They showed that the subset of two dozen FRBs that passed through galactic halos were indeed slowed down more than non-intersecting FRBs.

A few bright streakers flew by NASA’s meteor cameras, so get out now before the full moon overtakes the peak.
Look up now and you might spot some early shooting stars.
While the 2022 Perseid meteor shower is expected to peak between Aug. 11 and 12, NASA has already spotted some early arrivals.
Researchers may have solved Professor Stephen Hawking’s famous black hole paradox—a mystery that has puzzled scientists for almost half a century.
According to two new studies, something called “quantum hair” is the answer to the problem.
In the first paper, published in the journal Physical Review Letters, researchers demonstrated that black holes are more complex than originally thought and have gravitational fields that hold information about how they were formed.

We report on two extensions of the traditional analysis of low-dimensional structures in terms of low-dimensional quantum mechanics. On one hand, we discuss the impact of thermodynamics in one or two dimensions on the behavior of fermions in low-dimensional systems. On the other hand, we use both quantum wells and interfaces with different effective electron or hole mass to study the question when charge carriers in interfaces or layers exhibit two-dimensional or three-dimensional behavior.
