People who own all-electric cars where coal generates the power may think they are helping the environment. But a new study finds their vehicles actually make the air dirtier, worsening global warming. Ethanol isn't so green, either. The study examines environmental costs for cars' entire lifecycle, including where power comes from and the environmental effects of building batteries.
A new study from Massachusetts Institute of Technology implicates a family of RNA-binding proteins in the regulation of cancer, particularly in a subtype of breast cancer. These proteins, known as Musashi proteins, can force cells into a state associated with increased proliferation.
Supercritical Fluid Technologies has introduced a new, high-pressure reactor specifically designed for small batch reaction chemistry. The HPR-Micro reactor is a suitable high-pressure reactor for early, exploratory research. The microreactor comes standard with a 10-mL Iconel 718 reactor vessel for operation up to 10,000 psi (689 Bar/68.9 MPa), inlet and outlet valves and a pressure gauge.
Omega Engineering’s DRSL-DC4 provides a competitive choice in terms of both price and technology for galvanic isolation and conversion of bipolar process voltage or current signals to unipolar signals. The CE-compliant unit features a fast response time of less than 7 msec, excellent output load stability, slimline housing and multiple signal ranges.
The Internet is a massive place, linking billions of devices which share data that should exceed the zettabyte mark by 2016. Even as data transfer grows, the number of devices connected to the Internet will soon experience a geometric rise as well.
Scientists often test drugs in mice. Now some cancer patients are doing the same—with the hope of curing their own disease. They are paying a private lab to breed mice that carry bits of their own tumors so treatments can be tried first on the customized rodents. The idea is to see which drugs might work best on a specific person's cancer.
Credit card fraud and identify theft are serious problems for consumers and industries. Though corporations and individuals work to improve safeguards, it has become increasingly difficult to protect financial data and personal information from criminal activity. Fortunately, new insights into quantum physics may soon offer a solution.
Just in time for Christmas, Simon Fraser Univ. computing science professor Richard Zhang reveals how to print a 3-D Christmas tree efficiently and with zero material waste, using the world’s first algorithm for automatically decomposing a 3-D object into what are called pyramidal parts. A pyramidal part has a flat base with the remainder of the shape forming upwards over the base with no overhangs, much like a pyramid.
Engineers at Yale Univ. have discovered that the stiffness of liquid drops embedded in solids has something in common with Goldilocks: While large drops of liquids are softer than the solid that surrounds them, extremely tiny drops of liquid can actually be stiffer than certain solids. But when they’re “just right,” the liquid drops have the exact same stiffness as the surrounding solid.
Differences in local market conditions and policies, and other factors, particularly the size of the system, can lead to wide disparities in what consumers across the U.S. pay to install solar energy systems on their homes or small businesses, according to a recent study published by Lawrence Berkeley National Laboratory. This translates into thousands of dollars difference in the price of comparable solar energy systems around the U.S.
The rate at which carbon emissions warmed Earth's climate almost 56 million years ago resembles modern, human-caused global warming much more than previously believed but involved two pulses of carbon to the atmosphere, researchers at the Univ. of Utah, the Univ. of Michigan and three other universities found.
New findings could provide a pathway toward a kind of 2-D microchip that would make use of a characteristic of electrons other than their electrical charge, as in conventional electronics. The new approach is dubbed “valleytronics,” because it makes use of properties of an electron that can be depicted as a pair of deep valleys on a graph of their traits.
As the health care industry is undergoing a rapid transformation driven by evolving economic and regulatory demands, the biopharmaceutical industry also faces numerous challenges in meeting the needs of patients around the globe. Emerging markets are faced with the challenges of ensuring access to innovative, personalized treatments for patients with critical or rare conditions.
Reality isn’t always what it seems, as we learned in the groundbreaking film The Matrix. Neo, the movie’s hero, learns this lesson from a young monk who holds a spoon that bends and twists on its own, as if by magic. “Do not try and bend the spoon,” the boy tells Neo. “That’s impossible. Instead only try to realize the truth.”
When someone you know is wearing an unfamiliar hat, you might not recognize them. Georgia Institute of Technology researchers are using just such a disguise to sneak biomaterials containing peptide signaling molecules into living animals. When the disguised peptides are needed to launch biological processes, the researchers shine ultraviolet light onto the molecules through the skin, causing the "hat" structures to come off.
