Researchers Show Embryos Receive Parent-Specific Layers of Information

Study Reveals Embryos Receive Parent Specific Layers of Information

New research from San Francisco State University sheds light on the multilayered process of how a sperm and egg pass along information needed for successful reproduction, revealing that embryos receive parent-specific layers of information. The information that interprets the genetic code in a new embryo differs depending on whether it comes from the father or […]

Solid Nanoparticles Keep Their Internal Structure While Deforming Like a Liquid

New Research Shows Solid Nanoparticles Can Deform Like a Liquid

Using a combination of laboratory analysis and computer modeling, new research shows that nanoparticles keep their internal crystal structure while deforming like a liquid. A surprising phenomenon has been found in metal nanoparticles: They appear, from the outside, to be liquid droplets, wobbling and readily changing shape, while their interiors retain a perfectly stable crystal […]

Yale Biologists Describe DNA’s Security System

Surveillance of Nuclear Pore Complex Assembly

In a newly published study, Yale biologists and colleagues describe a key quality control mechanism that protects new cells from inheriting defective nuclear pore complexes. As befitting life’s blueprint, DNA is surrounded by an elaborate security system that assures crucial information is imparted without error. The security is provided by a double membrane perforated by […]

Lunar Reconnaissance Orbiter Finds Evidence of “Recent” Lunar Volcanism

NASA Finds Evidence of Young Volcanism on the Moon

New data from NASA’s Lunar Reconnaissance Orbiter reveals evidence of basaltic volcanism on the Moon occurring within the past 100 million years. NASA’s Lunar Reconnaissance Orbiter (LRO) has provided researchers strong evidence the moon’s volcanic activity slowed gradually instead of stopping abruptly a billion years ago. Scores of distinctive rock deposits observed by LRO are […]

New Hubble Image: Turquoise-Tinted Plumes in the LMC

Hubble Views Turquoise Tinted Plumes in the Large Magellanic Cloud

This newly released Hubble image shows part of the Tarantula Nebula, which is located in the Large Magellanic Cloud. The brightly glowing plumes seen in this image are reminiscent of an underwater scene, with turquoise-tinted currents and nebulous strands reaching out into the surroundings. However, this is no ocean. This image actually shows part of […]

Neutron Scattering Experiments Reveal New Quantum Properties of H2O and H2

Physicists Reveal New Quantum Properties of H2O and H2

New neutron scattering experiments reveal the existence of quantum selection rules in molecules and could open the door to new insights about the quantum properties of molecules by providing a unique testing ground for quantum theory. Neutron scattering experiments at the Institute Laue-Langevin (ILL) have uncovered the first known quantum selection rule in molecules, a […]

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 […]

NASA Prepares For Comet’s Close Encounter with Mars

NASA Prepares for Comet Siding Spring to Pass Mars

NASA is preparing its science fleet for comet Sliding Spring’s close encounter with Mars, which will occur on October 19 when Sliding Spring passes within about 87,000 miles of the Red Planet. NASA’s extensive fleet of science assets, particularly those orbiting and roving Mars, have front row seats to image and study a once-in-a-lifetime comet […]

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 […]
