futureLarge amounts of high density MRAM data could enable pinhead size computers

No Comments
new research from the University of New Hampshire will make computers the size of a pinhead a reality sooner than once thought. Researchers outline their proposed combination which would allow for a more stable perpendicular anisotropic energy (PMA), the key …

diseaseArtificial pancreas shows improved results but longer studies needed to show cost effectiveness

No Comments
Artificial pancreas treatment, also referred to as closed loop glucose control, is an emerging treatment option combining an insulin pump and continuous glucose monitoring with a control algorithm to deliver insulin in a glucose responsive manner (that is, a single …

astronomyDark matter might be primordial black holes

No Comments
Astronomers studying the motions of galaxies and the character of the cosmic microwave background radiation came to realize in the last century that most of the matter in the universe was not visible. About 84 percent of the matter in …

historyAncient industrial civilizations would be very hard to detect

No Comments
Centauri Dreams and The Atlantic have articles that consider if would we know if an early mammal built a civilization in the last 60 million years? Let’s assume a civilization lasting no more than 100,000 years, which turns out to …

futureHolographic sails fixes last technical issues for interstellar laser pushed sails

No Comments
Greg Matloff and his wife, C Bangs, have researched the use of holographic films for solar and laser pushed space sails. Matloff’s work is described at Centauri Dreams. Greg Matloff is on the Advisor’s Board of Yuri Milner’s $100 million …

No Comments
The U.S. Army Research Laboratory’s Center for Unmanned Aircraft Systems Propulsion made an historic first with its experiment in a gas turbine combustor using X-rays. The data will help advance gas turbine engine designs for higher power density and efficiency, …

commercializationRoll-to-roll chemical vapor deposition system makes long sheets of high quality graphene

No Comments
MIT has combined a roll-to-roll approach — a common industrial approach for continuous processing of thin foils — with the common graphene-fabrication technique of chemical vapor deposition, to manufacture high-quality graphene in large quantities and at a high rate. The …

energyThin film converts low grade waste heat to electricity at 19% of carnot efficiency

No Comments
Nearly 70 percent of the energy produced in the United States each year is wasted as heat. Much of that heat is less than 100 degrees Celsius and emanates from things like computers, cars or large industrial processes. Engineers at …

energyGeneral principles found to speed up the hunt for room temperature superconductors

No Comments
Scientists from Moscow Institute of Physics and Technology and Skoltech have demonstrated the high-temperature superconductivity of actinium hydrides and discovered a general principle for calculating the superconductivity of hydrides based on the periodic table alone. They have used a new …
