Researchers from CNRS, the Curie Institute, and Sorbonne University have successfully physically acted on chromosomes in live cells for the first time. They found that, outside of cell division phases, chromosomes are actually very fluid—almost liquid—by subjecting to different forces using magnets. The study was recently published in the prestigious journal Science.

When they are not in their division phases, chromosomes are fluid, though not quite liquid. This discovery was made possible by the first-ever direct mechanical manipulation of chromosomes in the nucleus of live cells.

Previously, chromosomes, which are extraordinarily long DNA.

Researchers have been growing brain organoids for several years, but not all organoids are created the same. It can vary from lab to lab — and even from batch to batch — which means that a finding made in one organoid may not hold true in another.

The world has one more sloth species in it than previously thought. Maned sloths live in a small belt of forest in Brazil and an analysis now suggests those in the south are a different species from those found farther north.

Three-toed sloths were conventionally thought to be divided into four species. One — the maned sloth (Bradypus torquatus) — sports a thatch of coarse, brown hair, making the head resemble a husked coconut.

Maned sloths were thought to be one species but a genetic and physical analysis suggests there are actually two.

Circa 2019

Lodestone, a naturally-occurring iron oxide, was the first persistently magnetic material known to humans. The Han Chinese used it for divining boards 2,200 years ago; ancient Greeks puzzled over why iron was attracted to it; and, Arab merchants placed it in bowls of water to watch the magnet point the way to Mecca. In modern times, scientists have used magnets to read and record data on hard drives and form detailed images of bones, cells and even atoms.

Throughout this history, one thing has remained constant: Our magnets have been made from solid materials. But what if scientists could make magnetic devices out of liquids?

When cancer develops in the body, it begins with tumor cells that rapidly multiply and divide before spreading. But how are these nascent tumor cells able to evade the body’s immune system, which is designed to recognize and defend against such faulty cells? The answer to this long-unsolved topic may hold the key to more successful cancer treatments — medications that block tumors’ subversive moves and allow the immune system to do its job.

Researchers at Harvard Medical School have now discovered a mechanism through which tumor cells can disable the immune system, enabling the tumor to spread unchecked. The study, which was conducted primarily in mice and published today in Science, demonstrates that tumor cells with a certain mutation generate a chemical, known as a metabolite, that weakens adjacent immune cells, making them less capable of eliminating cancer cells.

The results underscore the crucial roles played by tumor metabolites in the deactivation of the immune system by malignancies. The findings also highlight the crucial part that the tumor microenvironment—the region around the tumor—plays in the development of cancer.

Block coding converts text-based software code into a visual block format. It helps reduce probable errors. It is used to construct games, apps, and other programs. Users just need to drag and drop visual block coding representations of text-based code into the code editor. Blocks are chunks of instructions a user leverages to create their invention. Sprites can move and turn themselves and other sprites. The sprite can be taken a few steps forward or turned by a few degrees. They can be moved to the right or left with just one block. Blocks are used to change the form of a sprite. They can make the sprite think or talk or do anything. It can dress them up differently or the scale or graphic effects of a sprite. Kids can also use sound blocks are add audio effects to a tale or game. They can also adjust sound effects by varying the pitch and changing the depth of different sounds.

Syntax-free programming

Block-based coding doesn’t involve complex syntax. You can focus on areas that seem more complex and need more attention. The best thing about syntax-free programming is that it helps avoid minor syntax errors.

Summary: Oxytocin, a hormone connected with bonding and love, could help to heal damage following a heart attack. Researchers found oxytocin stimulates stem cells from the heart’s outer layer and migrates into the middle layer where it develops into muscle cells that generate heart contractions. This could be used to promote the regeneration of heart cells following a heart attack.

The neurohormone oxytocin is well-known for promoting social bonds and generating pleasurable feelings, for example from art, exercise, or sex. But the hormone has many other functions, such as the regulation of lactation and uterine contractions in females, and the regulation of ejaculation, sperm transport, and testosterone production in males.
