Previously Unknown Mechanism Repairs Brain after Stroke

Researchers Discover Mechanism that Repairs Brain after Stroke

Working with mice, researchers from Lund University and the Karolinska Institute have discovered a previously unknown mechanism through which the brain produces new nerve cells after a stroke. The findings have been published in the journal Science. A stroke is caused by a blood clot blocking a blood vessel in the brain, which leads to […]

New Method to Control Nanoparticles with Light and Magnets

Researchers Control Nanoparticles with Light and Magnets

A team of researchers has developed particles that can glow with color-coded light and be manipulated with magnets, improving the likelihood of tracking the position of the nanoparticles as they move within the body or inside a cell. A long-sought goal of creating particles that can emit a colorful fluorescent glow in a biological environment, […]

Researchers Uncover Molecular Process in the Brain that Transforms White Fat into Brown Fat

Researchers Uncover Molecular Process that Transforms White Fat into Brown Fat

Yale scientists uncover how a molecular process in the brain that known to control eating transforms white fat into brown fat, impacting how much energy we burn and how much weight we can lose. The results are published in the October 9 issue of the journal Cell. Obesity is a rising global epidemic. Excess fatty […]

Hubble Measures Temperature and Water Vapor on Exoplanet WASP-43b

Hubble Maps Temperature and Water Vapor on WASP-43b

A team of astronomers used NASA’s Hubble Space Telescope to make the most detailed global map yet of the glow from a turbulent planet outside our solar system, measuring the temperature and tracing the amount and distribution of water vapor on exoplanet WASP-43b. Hubble observations show the exoplanet, called WASP-43b, is no place to call […]

Astrophysicists Reveal Amount of Dark Matter is Less Than Previously Thought

Dark Matter Distribution Around the Milky Way Less Than Thought

New research from the University of Western Australia reveals that the amount of dark matter in the Milky Way is half as much as previously thought. Australian astronomers used a method developed almost 100 years ago to discover that the weight of dark matter in our own galaxy is 800,000,000,000 (or 8 x 1011) times […]

Researchers Detail the Structure and Dynamics of the HIV Spike Protein

Scientists Capture Images of the Protein HIV Uses to Infect Cells

In two newly published studies, researchers detail the structure and dynamics of the HIV spike protein, which is used by the virus uses to fuse with and enter cells. HIV is adept at eluding immune system responses because the protein it uses to infect cells is constantly changing. Now a team of researchers including scientists […]

Yale Engineers Develop Hybrid System for Quantum Communication

Yale Engineers Develop System for Quantum Communication

Using microwaves and magnets, researchers at the Yale School of Engineering & Applied Science developed a hybrid system for quantum communication. Yale engineers have developed a hybrid system that strongly couples magnons—the smallest unit of measurement for a magnetic spin excitation—with microwave photons. According to the researchers, the hybrid system achieved an ultrahigh coherence between […]

NuSTAR Discovers Brightest Pulsar to Date

NuSTAR Discovers Shockingly Bright Dead Star

Using NASA’s Nuclear Spectroscopic Telescope Array, astronomers have detected the brightest pulsar to date, located about 12 million light-years away in the galaxy Messier 82. Astronomers have found a pulsating, dead star beaming with the energy of about 10 million suns. This is the brightest pulsar – a dense stellar remnant left over from a […]
