This is an artistic representation of a two-photon source: The monolayer (below) emits exactly two photons of different frequencies under suitable conditions. They are depicted in red and green in the picture.

Faced with the thousands of proteins and genes found in virtually every cell in the body, biologists want to know how they all work exactly: How do they interact to carry out their specific functions and how do they respond and adapt to perturbations? One of the crucial factors in all of these processes is the question of how biomolecules react to the minuscule forces that operate at the molecular level. LMU physicists led by Professor Tim Liedl, in collaboration with researchers at the Technical University in Braunschweig and at Regensburg University, have come up with a method that allows them to exert a constant force on a single macromolecule with dimensions of a few nanometers, and to observe the molecule's response. The researchers can this way test whether or not a protein or a gene is capable of functioning normally when its structure is deformed by forces of the magnitude expected in the interior of cells. This new method of force spectroscopy uses self-assembled nanoscopic power gauges, requires no macroscopic tools and can analyze large numbers of molecules in parallel, which speeds up the process of data acquisition enormously.

on landing-day data. This is within the planned landing area and about 3.3 miles (5.4 kilometers) west of the center of the landing target. A dark spot is larger and elliptical, approximately 50 by 130 fee

The study, conducted by researchers at Princeton University and the University of Texas-Austin was published Oct. 21, in the journal Science. The study demonstrates that the electrons, when kept at very low temperatures where their quantum behaviors emerge, can spontaneously begin to travel in identical elliptical paths on the surface of a crystal of bismuth, forming a quantum fluid state. This behavior was anticipated theoretically during the past two decades by researchers from Princeton and other universities.

Matters of the heart can be puzzling and mysterious -- so too with unusual astronomical objects called heartbeat stars.

NASA’s Mars Reconnaissance Orbiter has identified new markings on the surface of the Red Planet that are believed to be related to ESA’s ExoMars Schiaparelli entry, descent and landing technology demonstrator module.

NASA's Voyager 2 spacecraft flew by Uranus 30 years ago, but researchers are still making discoveries from the data it gathered then. A new study led by University of Idaho researchers suggests there could be two tiny, previously undiscovered moonlets orbiting near two of the planet's rings.

Boeing has installed a new P-8A Poseidon training center at Naval Air Station Whidbey Island, Wash., as the base begins preparations for the arrival of P-8 aircraft beginning in 2017.

Every electronic device -- from a supercomputer to a dishwasher -- works by controlling the flow of charged electrons. But electrons can carry so much more information than just charge; electrons also spin, like a gyroscope on axis.

Santosh Thapa, PhD Fellow at the US based University of North Texas Health Science Center and one of the members of the Organizing Committee informed us that “More than 140 research papers on recent advancement in material sciences and engineering will be presented during the four days long KaSAM-2016. The technical program comprises of Keynote Lectures, Oral Presentations and Poster Session in the related field along with a special symposium on ‘Science, Technology & Innovations for Nepal’. A short course on ‘Recent developments and research trends in nanomaterials’ has also been arranged for young scientist and students, in the first day of the conference.”
