New Formula Improves Liquid Battery Technology

New Formula Leads to Improved Liquid Battery

MIT engineers have developed an improved liquid battery system that could enable renewable energy sources to compete with conventional power plants. Extensive testing has shown that even after 10 years of daily charging and discharging, the system should retain about 85 percent of its initial efficiency. Donald Sadoway and colleagues have already started a company […]

MAVEN Spacecraft Successfully Enters Mars’ Orbit

Animation Shows MAVEN Orbiting Mars

After a 10-month journey, NASA has confirmed that the MAVEN spacecraft has successfully entered Mars’ orbit. NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft successfully entered Mars’ orbit at 10:24 p.m. EDT Sunday, September 21, where it now will prepare to study the Red Planet’s upper atmosphere as never done before. MAVEN is the first […]

Yale Study Shows Estrogen Helps Calm Stressed Cells

Yale Study Shows Estrogen Helps Calm Stressed Cells

New research from Yale University shows that the hormone estrogen helps cells survive stress, fueling speculation that anti-estrogen therapy may help kill cancer cells and prolong the survival of patients. Stress is as bad for cells as it is for people, but scientists have had a hard time devising ways to study its effects on […]

New Hubblecast Video Explores the South Atlantic Anomaly

Hubblecast 77 Video Hubble and the Bermuda Triangle of Space

This newly released six minute video details the mysterious region known as the South Atlantic Anomaly – an area where the Earth’s inner Van Allen radiation belt comes close to the Earth’s surface, increasing the flux of energetic particles and exposes orbiting satellites to higher-than-usual levels of radiation. Hubblecast 77: Hubble and the Bermuda Triangle […]

Hubble Views Spiral Galaxy NGC 7793

Hubble Image of Spiral Galaxy NGC 7793

This newly released Hubble image shows spiral galaxy NGC 7793. This new image from the NASA/ESA Hubble Space Telescope shows NGC 7793, a spiral galaxy in the constellation of Sculptor some 13 million light-years away from Earth. NGC 7793 is one of the brightest galaxies in the Sculptor Group, and one of the closest groups […]

Phase-Change Materials Increase the Speed Limit for Computers

Phase Change Materials Increase the Speed Limit for Computers

By replacing silicon with phase-change materials, new research shows that computers could be capable of processing information up to 1,000 times faster than currently models. The present size and speed limitations of computer processors and memory could be overcome by replacing silicon with ‘phase-change materials’ (PCMs), which are capable of reversibly switching between two structural […]

New Graphene Sensor Detects Cancer Biomarkers

New Sensor Tracks Down Cancer Biomarkers

Scientists from the University of Swansea have developed an ultrasensitive graphene biosensor that can detect molecules that indicate an increased risk of developing cancer. The biosensor has been shown to be more than five times more sensitive than bioassay tests currently in use, and was able to provide results in a matter of minutes, opening […]

Large Galaxies Gain Size by Merging with Smaller Neighbors

Monster Galaxies Gain Size by Consuming Smaller Neighbors

A newly published study examined galaxy growth, revealing that massive galaxies are much less efficient at star formation than smaller galaxies and instead grew by merging other galaxies. Massive galaxies in the Universe have stopped making their own stars and are instead snacking on nearby galaxies, according to research by Australian scientists. Astronomers looked at […]

Chimps Engage in Violent Behavior Regardless of Human Effects on Local Ecology

Study Shows Deadly Violence a Natural Tendency in Chimps

Using data collected from 18 chimpanzee research sites, a newly published study shows that chimps engage in violent and sometimes lethal behavior regardless of human effects on local ecology. For decades, scientists studying chimpanzees in the wild have noted the ways our closest relatives are similar to humans — they form tightly knit social groups, […]

Engineers Develop New Temperature Switchable Membrane to Regulate Flow

Researchers Develop New Temperature Switchable Membrane

Researchers from the University of Connecticut and Yale University have developed a new membrane with highly aligned nanoscale pores that open and close in response to temperature; this highly porous, valve-like material has many potential filtration applications, including water purification and molecular separation. The membrane was created from a block copolymer that self-assembles into alternating […]

Harvard Study Confirms Distance to the Pleiades Cluster

VLBI Resolution of the Pleiades Distance Controversy

Astronomers from the Harvard-Smithsonian Center for Astrophysics have completed a new distance measurement to the Pleiades Cluster, strengthening the existing astrophysical models and contradicting an earlier distance result that challenged those models. The Pleiades star cluster, a brilliant collection of several hundred stars visible in the winter sky near the constellation of Orion, has been […]

Liquid Inks Create More Efficient and Cheaper Solar Cells

Researchers Create Better Solar Cells with Liquid Inks

A team of scientists from the California NanoSystems Institute is using liquid inks to create better solar cells, improving efficiency and lowering costs. The basic function of solar cells is to harvest sunlight and turn it into electricity. Thus, it is critically important that the film that collects the light on the surface of the […]
