Future increases in U.S. natural gas exports not as large as thought

August 15, 2012 8:42 am | News | Comments

Amid policy debate over potential liquefied natural gas (LNG) exports from the United States, a new paper from Rice University's Baker Institute for Public Policy predicts the long-term volume of exports from the U.S. will not likely be very large. The paper also argues that the impact on U.S. domestic natural gas prices will not be large if exports are allowed by the U.S government.

Success of engineered tissue depends on where it's grown

August 15, 2012 4:57 am | by Anne Trafton, MIT News Office | News | Comments

Tissue implants made of cells grown on a sponge-like scaffold have been shown in clinical trials to help heal arteries scarred by atherosclerosis and other vascular diseases. However, it has been unclear why some implants work better than others. Massachusetts Institute of Technology researchers have now shown that implanted cells' therapeutic properties depend on their shape, which is determined by the type of scaffold on which they are grown.

Impulsive micromanagers help plants to adapt, survive

August 14, 2012 10:02 am | News | Comments

Soil microbes are impulsive. So much so that they help plants face the challenges of a rapidly changing climate. Michigan State University biologists studied how plants and microbes work together to help plants survive the effects of global changes, such as increased atmospheric carbon dioxide concentrations, warmer temperatures, and altered precipitation patterns.

Photos reflect light like 3D objects with novel printing technology

August 14, 2012 4:48 am | News | Comments

A novel printing method yields photos that respond to different angles of light the same way a 3D object does. The technique, which uses specially designed "reflectance paper" covered with thousands of tiny dimples, was developed by a team of researchers at the University of California, Santa Cruz; Hewlett-Packard Laboratories; and 3M.

August 13, 2012 8:48 am | News | Comments

Thermo Fisher Scientific Inc. has entered into a technology alliance partnership agreement with scientists at Princeton University, establishing a formal collaboration to accelerate research in triple quadrupole and high-resolution accurate mass liquid chromatography-mass spectrometry for life science applications.

Scientists' gold discovery sheds light on catalysis

August 13, 2012 7:20 am | News | Comments

An international team of researchers has discovered that the catalytic activity of nanoporous gold originates from high concentrations of surface defects present within its complex 3D structure. The research has the potential to assist in the development of more efficient and durable catalytic converters and fuel cells because nanoporous gold is a catalytic agent for oxidizing carbon monoxide.

Team discovers how stress, depression can shrink the brain

August 13, 2012 6:42 am | News | Comments

Major depression or chronic stress can cause the loss of brain volume, a condition that contributes to both emotional and cognitive impairment. Now a team of researchers led by Yale University scientists has discovered one reason why this occurs—a single genetic switch that triggers loss of brain connections in humans and depression in animal models.

Researchers make optical fibers from common materials

August 13, 2012 5:58 am | News | Comments

Clemson University researchers are taking common materials to uncommon places by transforming easily obtainable and affordable materials into fiber. The research team found that sapphire possesses extraordinary properties that make it exceptionally valuable for high-power lasers in which the light intensity interacts with sound waves in the glass and leads to diminished power-handling capabilities.

Unraveling intricate interactions, one molecule at a time

August 13, 2012 4:37 am | News | Comments

A team of researchers at Columbia Engineering, in collaboration with Brookhaven National Laboratory, has succeeded in performing the first quantitative characterization of van der Waals interactions at metal/organic interfaces at the single-molecule level.

Graphene's behavior depends on where it sits

August 13, 2012 3:41 am | by David L. Chandler, MIT News Office | News | Comments

When you look at a gift-wrapped present, the basic properties of the wrapping paper are not generally changed by the nature of the gift inside. But surprising new experiments conducted at the Massachusetts Institute of Technology show that graphene behaves quite differently depending on the nature of material it's wrapped around. When sheets of graphene are placed on substrates made of different materials, fundamental properties can be drastically different, depending on the nature of the underlying material.

Scientist discovers plate tectonics on Mars

August 10, 2012 7:19 am | News | Comments

For years, many scientists had thought that plate tectonics existed nowhere in our solar system but on Earth. Now, a University of California, Los Angeles scientist has discovered that the geological phenomenon, which involves the movement of huge crustal plates beneath a planet's surface, also exists on Mars.

Soft autonomous robot inches like earthworm

August 10, 2012 4:09 am | by Jennifer Chu, MIT News Office | News | Comments

Earthworms creep along the ground by alternately squeezing and stretching muscles along the length of their bodies, a mechanism called peristalsis, inching forward with each wave of contractions. Now researchers at Massachusetts Institute of Technology, Harvard University, and Seoul National University have engineered a soft autonomous robot that moves via peristalsis, crawling across surfaces by contracting segments of its body, much like an earthworm.

Gecko feet hold clues to creating bandages that stick when wet

August 10, 2012 3:45 am | News | Comments

Scientists already know that the tiny hairs on geckos' toe pads enable them to cling, like Velcro, to vertical surfaces. Now, University of Akron researchers are unfolding clues to the reptiles' gripping power in wet conditions in order to create a synthetic adhesive that sticks when moist or on wet surfaces.

Cheaper, cleaner, more efficient catalyst for burning methane

August 9, 2012 12:06 pm | News | Comments

Researchers from the University of Pennsylvania, along with collaborators from Italy and Spain, have created a material that catalyzes the burning of methane 30 times better than currently available catalysts. The discovery offers a way to more completely exploit energy from methane, potentially reducing emissions of this greenhouse gas from vehicles that run on natural gas.

Using years of cell evolution in the fight against cancer

August 9, 2012 8:47 am | News | Comments

As the medical community continues to make positive strides in personalized cancer therapy, scientists know some dead ends are unavoidable. Drugs that target specific genes in cancerous cells are effective, but not all proteins are targetable. In fact, it has been estimated that as few as 10% to 15% of human proteins are potentially targetable by drugs. For this reason, Georgia Institute of Technology researchers are focusing on ways to fight cancer by attacking defective genes before they are able to make proteins.

Simple mathematical computations underlie brain circuits

August 9, 2012 7:37 am | by Anne Trafton, MIT News Office | News | Comments

The brain has billions of neurons, arranged in complex circuits that allow us to perceive the world, control our movements, and make decisions. Deciphering those circuits is critical to understanding how the brain works and what goes wrong in neurological disorders. Massachusetts Institute of Technology neuroscientists have now taken a major step toward that goal.
