Neurons That Control Hunger Could Help Control Autoimmune Diseases

Neurons That Control Hunger Could Help Control Autoimmune Diseases

Researchers at the Yale School of Medicine have discovered that hunger-spiking neurons could help control autoimmune diseases, unmasking a previously unsuspected role of hypothalamic feeding circuits in the regulation of adaptive immune response. Neurons that control hunger in the central nervous system also regulate immune cell functions, implicating eating behavior as a defense against infections […]

New Research Shows That Ephemeral Vacuum Particles Induce Speed-of-Light Fluctuations

New Research Shows That the Speed of Light May Not Be Fixed

Two newly published studies challenge established wisdom about the nature of vacuum, finding that ephemeral vacuum particles induce speed-of-light fluctuations. In one paper, Marcel Urban from the University of Paris-Sud, located in Orsay, France and his colleagues identified a quantum level mechanism for interpreting vacuum as being filled with pairs of virtual particles with fluctuating […]

Scientists Discover a New Type of Supernova

Researchers-Discover-a-New-Kind-of-Supernova Called Type Iax

Astronomers have discovered a new type of supernova that may not completely destroy the white dwarf. Called Type Iax, this new supernova is fainter and less energetic than Type Ia. Cambridge, Masachusetts – Until now, supernovas came in two main “flavors.” A core-collapse supernova is the explosion of a star about 10 to 100 times […]

Rejuvenating Blood by Re-Programming Stem Cells

Rejuvenating Blood by Reversing the Stem Cells that Produce Blood

In a new study, researchers from Lund University detail how they succeeded in rejuvenating the blood of mice by re-programming the stem cells that produce blood. The blood of young and old people differs. In an article published recently in the scientific journal Blood, a research group at Lund University in Sweden explain how they […]

How Down Syndrome and Low SNX27 Are Connected

How Down Syndrome and Low SNX27 Are Connected

In a newly published study, researchers show how Down syndrome and low SNX27 are connected, discovering that the extra chromosome inherited in Down syndrome impairs learning and memory because it leads to low levels of SNX27 protein in the brain. What is it about the extra chromosome inherited in Down syndrome—chromosome 21—that alters brain and […]

Sugar-Sweetened Beverages Linked to About 180,000 Deaths Annually

180000 Deaths Worldwide May Be Associated with Sugary Soft Drinks

New research suggests that sugar-sweetened beverages may be linked to about 180,000 deaths in the world each year. Study Highlights: Sugar-sweetened beverages may be linked to about 180,000 deaths in the world each year. Countries in the Caribbean/Latin America had among the highest death rates from diabetes due to consumption of sugary beverages. About 25,000 […]

A New Kind of Invisibility Cloak Demonstrates Better Cloaking Efficiency

Invisibility Cloak Research Moves Forward

Using a new kind of cloak that uses a very thin multilayer dielectric coating made of natural material, not metamaterial, researchers at Michigan Technological University demonstrated better cloaking efficiency than a similarly sized metamaterial cloak designed by using the transformation optics relations. Michigan Technological University’s invisibility cloak researchers have done it again. They’ve moved the […]

Hubble Views Worm-Like Galaxy IRAS 23436+5257

Hubble Spots Galaxy IRAS 23436 5257

In this new image captured by the NASA/ESA Hubble Space Telescope, you can see the worm-like galaxy known as IRAS 23436+5257. The shape is most likely the result of a collision and subsequent merger of two galaxies. This charming and bright galaxy, known as IRAS 23436+5257, was captured by the NASA/ESA Hubble Space Telescope. It […]

Volcanic Activity Triggered the End-Triassic Extinction

Volcanic Eruptions Triggered the End Triassic Extinction

In a new study, researchers from MIT provide evidence that volcanic activity did indeed trigger the end-Triassic extinction, killing off 76 percent of marine and terrestrial species on Earth. More than 200 million years ago, a massive extinction decimated 76 percent of marine and terrestrial species, marking the end of the Triassic period and the […]

Researchers Study Early Galaxies and Their Specific Properties

The Shape of Galaxies in the Early Universe

Using data from the CANDELS project, scientists examine early galaxies and their specific properties, finding that star formation in blue galaxies have undergone collisions that induce star formation that makes them shine exceptionally brightly. Galaxies today come very roughly in two types: reddish, elliptically shaped collections of older stars, and bluer, spiral shaped objects dominated […]
