Viewing a catalytic reaction in action

Researchers monitors the steps of a chemical reaction mediated by a metallic surface

06-May-2016

To be able to follow and directly visualize how the structure of molecules changes when they undergo complex chemical transformations has been a long-standing goal of chemistry. While reaction intermediates are particularly difficult to identify and characterize due to their short lifetimes, ...

Light-powered 3-D printer creates terahertz lens

02-May-2016

From visible light to radio waves, most people are familiar with the different sections of the electromagnetic spectrum. But one wavelength is often forgotten, little understood, and, until recently, rarely studied. It's called terahertz, and it has important applications in imaging and ...

Superfast light source made from artificial atom

29-Apr-2016

All light sources work by absorbing energy - for example, from an electric current - and emit energy as light. But the energy can also be lost as heat and it is therefore important that the light sources emit the light as quickly as possible, before the energy is lost as heat. Superfast light ...

New method for exhaustively isolating olfactory receptors responding to specific odorants

29-Apr-2016

A research group led by Osaka University and Panasonic Corporation developed a method for making a prompt, exhaustive isolation of olfactory receptors (ORs) responding to the odorant of interest. This achievement will enable quick and easy exhaustive analysis of ORs responding to specific ...

Chemists use DNA to build the world's tiniest thermometer

28-Apr-2016

Researchers at University of Montreal have created a programmable DNA thermometer that is 20,000x smaller than a human hair. This scientific advance reported this week in the journal Nano Letters may significantly aid our understanding of natural and human designed nanotechnologies by enabling to ...

The gates of serotonin

Cracking the workings of a notorious receptor

25-Apr-2016

EPFL scientists have elucidated for the first time how a notoriously elusive serotonin receptor functions with atom-level detail. The receptor transmits electrical signals in neurons and is involved in various disorders, meaning that the discovery opens the way for new treatments. Serotonin is a ...

Cellphone principles help microfluidic chip digitize information on living cells

22-Apr-2016

Phone calls and text messages reach you wherever you are because your phone has a unique identifying number that sets you apart from everybody else on the network. Researchers at the Georgia Institute of Technology are using a similar principle to track cells being sorted on microfluidic ...

Predicting Cell Behaviour with a Mathematical Model

Heidelberg physicists develop new software for the life sciences

20-Apr-2016

Scientists from Heidelberg University have developed a novel mathematical model to explore cellular processes: with the corresponding software, they now are able to simulate how large collections of cells behave on given geometrical structures. The software supports the evaluation of ...

First-ever videos show how heat moves through materials at the nanoscale and speed of sound

18-Apr-2016

Using a state-of-the-art ultrafast electron microscope, University of Minnesota researchers have recorded the first-ever videos showing how heat moves through materials at the nanoscale traveling at the speed of sound. The research, published today in Nature Communications, provides unprecedented ...

Clearing the way for real-world applications of superhydrophobic surfaces

Researchers call for consistent and standardized testing of superhydrophobic materials.

12-Apr-2016

Agreeing on a unified testing method is needed to allow community-wide comparison between published results. This would significantly progress development of superhydrophobic materials and their transfer to commercial products in, for instance, self-cleaning and anti-icing ...
