Researchers Build 3-D Structures Out of Liquid Metal

Researchers from North Carolina State University have developed three-dimensional (3-D) printing technology and techniques to create free-standing structures made of liquid metal at room temperature.

“It’s difficult to create structures out of liquids, because liquids want to bead up. But we’ve found that a liquid metal alloy of gallium and indium reacts to the oxygen in the air at room temperature to form a ‘skin’ that allows the liquid metal structures to retain their shapes,” says Dr. Michael Dickey, an assistant professor of chemical and biomolecular engineering at NC State and co-author of a paper describing the work.

“Liebe und Romantik”, So denke ich darüber: Katja (30)

Culture, Interview, Media

Q. Was ist Liebe? Wie würden Sie es definieren?

Katja: Ja, es ist sehr schwierig zu definieren, was Liebe ist. Man kann es schlecht beschreiben, also man liebt ja doch, ich würde sagen mehrere Menschen. Also das Gefühl jemanden gern zu haben, zu mögen….und ja schwierig zu definieren, die richtige Liebe, aber was ist richtige Liebe?…ja..(lächeln)

Q. Was ist Ihr liebstes Liebes-Zitat? Lesen Sie Liebesgedichte?

Katja: Ahh…so richtig lese ich jetzt Liebesgedichte nicht, aber für mich hat jemand ein Liebesgedicht geschrieben und das war sehr schön und da war ich wirklich gerührt und also es hat mich beflügelt, dass jemand für mich ein Liebesgedicht schreibt. Das Gedicht war echt schön, dass man so was denken und fühlen kann. (more…)

Questions for Jack Mustard: Helping to shape a new Mars rover

Science

In 2020, a new-generation Mars rover will land on the Red Planet and gather much more detailed data than Curiosity, which is on Mars now. NASA revealed details about the new rover at a news conference Tuesday, July 9, 2013. Brown University’s Jack Mustard chaired the Mars 2020 Science Definition Team.

PROVIDENCE, R.I. [Brown University] — NASA unveiled details about a new rover proposed to land on the surface of Mars in 2020. The details came in the form of a 154-page document prepared by the Mars 2020 Science Definition Team, which was tasked with recommending scientific objectives of the mission. (more…)

Are Christians becoming more ‘green’?

Environment

Despite the wide-held perception that Christians have become more concerned about the environment, new research finds this so-called “greening of Christianity” is not evident among the religious rank-and-file. (more…)

Computer modeling shows crucial function of water molecules in proteins

Science

Using molecular simulations that modeled a potassium channel and its immediate cellular environment, atom for atom, UChicago scientists have discovered that just 12 molecules of water cause the long post-activation recovery period required by such ion channels before they can function again. The research has revealed a new mechanism in the function of a nearly universal biological structure that will have broad implications, ranging from fundamental biology to the design of pharmaceuticals.

“Our research clarifies the nature of this previously mysterious inactivation state. This gives us better understanding of fundamental biology and should improve the rational design of drugs, which often target the inactivated state of channels,” said Benoît Roux, professor of biochemistry and molecular biology, whose team’s findings were published online July 28 in Nature.

Successful Test of New U.S. Magnet Puts Large Hadron Collider on Track for Major Upgrade

Science

U.S. Department of Energy national laboratories – including Berkeley Lab – collaborate to build the new magnets CERN needs to increase LHC luminosity by an order of magnitude

The U.S. LHC Accelerator Program (LARP) has successfully tested a powerful superconducting quadrupole magnet that will play a key role in developing a new beam focusing system for CERN’s Large Hadron Collider (LHC). This advanced system, together with other major upgrades to be implemented over the next decade, will allow the LHC to produce 10 times more high-energy collisions than it was originally designed for.

Dubbed HQ02a, the latest in LARP’s series of High-Field Quadrupole magnets is wound with cables of the brittle but high-performance superconductor niobium tin (Nb₃Sn). Compared to the final-focus quadrupoles presently in place at the LHC, which are made with niobium titanium, HQ02a has a larger aperture and superconducting coils designed to operate at a higher magnetic field. In a recent test at the Fermi National Accelerator Laboratory (Fermilab), HQ02a achieved all its challenging objectives. (more…)

CU-Boulder team develops new water splitting technique that could produce hydrogen

Science

A University of Colorado Boulder team has developed a radically new technique that uses the power of sunlight to efficiently split water into its components of hydrogen and oxygen, paving the way for the broad use of hydrogen as a clean, green fuel. (more…)
