MIT Engineers Develop New Magnetic-Field Detector That is 1,000 Times More Efficient

New Magnetic-Field Detector is 1,000 Times More Efficient

Engineers at MIT have developed a new, ultrasensitive magnetic-field detector that is 1,000 times more energy-efficient than its predecessors. The detectors could lead to better sensors for medical imaging and contraband detection. Magnetic-field detectors, or magnetometers, are already used for all those applications. But existing technologies have drawbacks: Some rely on gas-filled chambers; others work […]

Biologists Map the Habits of Cancer Cells

Scientists Map the Habits of Cancer Cells

Yale University researchers are mapping the habits of cancer cells, determining which cues cause cancer cells to disperse and metastasize, how these cues are combined with other cues directing the invasion, and which cues hold sway when there are conflicting orders. Using advanced technology and an approach that merges engineering and medicine, a Yale University-led […]

Astronomers Detail Seasonal, Year-Long Cycles Seen on the Sun

Astronomers View Seasonal Cycles Seen on the Sun

New research examines what creates the magnetic bands on the Sun and how they influence solar cycles, revealing that the changes in the magnetic field in the bands gives rise to a 330-day activity cycle on the sun that is observable but has often been downplayed and overlooked when trying to seek the cause of […]

Suzaku X-ray Satellite Reveals Pre-Explosion Mass of a White Dwarf Star

Astronomers Reveal Pre-Explosion Mass of a White Dwarf Star

A newly published study reveals that supernova remnant 3C 397 is the remains a single white dwarf that accumulated matter from a normal companion star. The white dwarf exploded as its mass neared 1.4 solar masses. Using archival data from the Japan-led Suzaku X-ray satellite, astronomers have determined the pre-explosion mass of a white dwarf […]

Hubble Image of the Week: The Crammed Center of Messier 22

New Hubble Image of Globular Cluster Messier 22

This newly released Hubble image shows the center of the globular cluster Messier 22, also known as M22. Globular clusters are spherical collections of densely packed stars, relics of the early years of the Universe, with ages of typically 12 to 13 billion years. This is very old considering that the Universe is only 13.8 […]

AZD05030 Restores Memory and Synapse Loss in Alzheimer Mice

Experimental Cancer Drug Restores Memory

New research from Yale University reveals that the experimental cancer drug AZD05030 blocks damage triggered during the formation of amyloid-beta plaques, restoring synaptic connections and memory in a mouse model of Alzheimer’s. Memory and as well as connections between brain cells were restored in mice with a model of Alzheimer’s given an experimental cancer drug, […]

Hubble Reveals Phantom Objects Near Dead Quasars

Hubble Reveals Phantom Objects Near Dead Stars

Astronomers have identified eight galaxies with bright active nuclei that have illuminated material far outside the radius of the galaxy. The eerie structures have looping, spiral, and braided shapes. Hubble’s images show that they are like the remnants of galaxy collisions. NASA’s Hubble Space Telescope has photographed a set of wispy, goblin-green objects that are […]

Herschel and Planck Identify Some of the Oldest and Rarest Galaxy Clusters

Astronomers Identified Some of the Oldest and Rarest Galaxy Clusters

By using data from ESA’s Herschel and Planck space observatories, astronomers have discovered what could be the precursors of the vast clusters of galaxies that we see today. One telescope finds the treasure chest, and the other narrows in on the gold coins. Data from two European Space Telescope missions, Planck and Herschel, have together […]

Mathematical Simulations Show Rocky Planets May Orbit Double Stars

Planet Formation Around Binary Stars

In a new study, astronomers used mathematical analysis and simulations to show that it is possible for a rocky planet to form around binary stars. To date, NASA’s Kepler space telescope has found only gas-giant planets like Saturn or Neptune orbiting binary stars. March 30, 2015 – Luke Skywalker’s home in “Star Wars” is the […]

Magnetic Fields Influence Star Formation on a Variety of Scales

Magnetic Fields Influence Star Formation

A newly published study from the Harvard-Smithsonian Center for Astrophysics reveals that magnetic fields influence star formation on a variety of scales, from hundreds of light-years down to a fraction of a light-year. Cambridge, Massachusetts – Stars form when gravity pulls together material within giant clouds of gas and dust. But gravity isn’t the only […]

HiRISE Images Reveal the Fading Scars of Mars Rover Landing

Scars on Mars from 2012 Rover Landing Fade

A series of observations from NASA’s Mars Reconnaissance Orbiter show how dark blast zones from the Curiosity rover have faded inconsistently. The High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter made the observations on multiple dates from landing to last month. After fading for about two years, the pace of change […]

Hubble Views Spiral Galaxy NGC 3021

This newly released Hubble image shows the spiral galaxy NGC 3021, which lies about 100 million light-years away in the constellation of Leo Minor. Among many other types of stars, this galaxy contains Cepheid variable stars, which can be used work out the distance to the galaxy. These stars pulsate at a rate that is […]

VLT Confirms G2 Survived Close Approach of Supermassive Black Hole

G2 Passes Supermassive Black Hole

New VLT observations confirm that the dusty gas cloud G2 made its closest approach to the supermassive black hole at the center of the Milky Way in May 2014 and has survived the experience. The new result from ESO’s Very Large Telescope shows that the object appears not to have been significantly stretched and that […]

New HIV Finding Dampens Hopes of an Impending Cure

New Finding Dampens Hopes of an HIV Cure

New research from Yale University shows that HIV can establish itself in the brain as soon as four months after initial infection, dampening the hopes of an impending cure for a disease that afflicts more than 35 million people. Within two years of infection, a genetically distinct version of HIV replicates in the brains of […]

New Findings Will Help Light the Way to Understanding Dark Energy

New Research Analyzes Several Sites Where Dead Stars Once Exploded

Astronomers used data from NASA’s Galaxy Evolution Explorer to analyze several sites where dead stars once exploded, revealing that the Type Ia supernovae affiliated with the hot, young stars were significantly more reliable at indicating distances than their counterparts. The brilliant explosions of dead stars have been used for years to illuminate the far-flung reaches […]
