Working in collaboration with colleagues from Imperial College London, Professor Iain Todd from the Department of Materials Science and Engineering at the University of Sheffield has been taking a novel approach to the development of engineering components produced using additive manufacturing.

When molecules interact with the oscillating field of a laser, an instantaneous, time-dependent dipole is induced. This very general effect underlies diverse physical phenomena such as optical tweezers, for which Arthur Ashkin received the Nobel Prize in Physics in 2018, as well as the spatial alignment of molecules by a laser field. Now scientists from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) report on an experiment in the Journal of Physical Chemistry Letters, where the dependence of the driven-dipole response on the bound state of an electron in a methyl iodine molecule is revealed.

In 'game-changing' finding, bone mass rose 800 percent after signals were blocked in brains of mice

Researchers from North Carolina State University, the University of North Carolina and Arizona State University have developed an intelligent system for "tuning" powered prosthetic knees, allowing patients to walk comfortably with the prosthetic device in minutes, rather than the hours necessary if the device is tuned by a trained clinical practitioner. The system is the first to rely solely on reinforcement learning to tune the robotic prosthesis.

Molecules are usually formed in reaction vessels or laboratory flasks. An Empa research team has now succeeded in producing molecules between two microscopically small, movable gold tips – in a sense as a "hand-knitted" unique specimen. The properties of the molecules can be monitored in real time while they are being produced. The research results have just been published in Nature Communications.

An international team led by ETH Zurich physicist Steven Johnson established that the famed Einstein-de Haas effect has a central role in ultrafast demagnetization processes

LED lights and monitors, and quality solar panels were born of a revolution in semiconductors that efficiently convert energy to light or vice versa. Now, next-generation semiconducting materials are on the horizon, and in a new study, researchers have uncovered eccentric physics behind their potential to transform lighting technology and photovoltaics yet again.

Idling in a long highway line of slowed or stopped traffic on a busy highway can be more than an inconvenience for drivers and highway safety officers.

World first experiments on sensor that may revolutionise everything from medical devices to unmanned vehicles

Electronegativity is one of the most well-known models for explaining why chemical reactions occur. Now, Martin Rahm from Chalmers University of Technology, Sweden, has redefined the concept with a new, more comprehensive scale. His work, undertaken with colleagues including a Nobel Prize-winner, has been published in the Journal of the American Chemical Society.

Texas Biomed scientists team up to study host and virus protein interaction

„Deorbiting“ Systems are to ensure less debris and more safety for satellites in space. Integrated into the space systems, these should allow them to burn up in the atmosphere deliberately after their mission ends. The commitment of the space operators to these measures and thus the associated technologies are still relatively young. With the space observation radar TIRA, the Fraunhofer FHR supports manufacturers and operators with analyzes of the systems in use, as such, providing important information on their correct function and how they can be further optimized for their important task.

Coral calcification: Microscope-guided microsensor measurements reveal full carbonate chemistry at the site of calcification in a tropical coral

Changes in blood vessels are the major cause of death and morbidity in diabetes. For the first time, scientists managed to grow perfect human blood vessels as organoids in a petri dish. This breakthrough engineering technology dramatically advances research of vascular dysfunction in diseases like diabetes, identifying a key pathway that prevents diabetic vasculopathy, as reported in the current issue of Nature.

Marine researchers from Warnemünde have succeeded in deciphering the mysterious feeding behaviour of mesozooplankton in the presence of blue-green algae blooms, by analysing stable nitrogen isotopes in amino acids. They found out that contradictory observations, according to which both the dominance of herbivorous and carnivorous diets occurred, can be explained by the aging process of a bloom. Apparently, the stage of a bloom determines whether "meat" or "vegetables" are preferred. In view of an assumed future worldwide increase in such blooms, their findings open up new perspectives on potential developments within a key group of the marine food web.

MD&M West in Anaheim, California is the largest American exhibition for design and manufacturing in medical technology. Visitors mainly include developers and decision-makers from the manufacturing industry. The show is enjoying increasing international popularity and has meanwhile firmly established itself as one of the top medical technology marketplaces for component manufacturers from Europe and Asia. This will also be demonstrated by the international joint booth of the IVAM Microtechnology Network in Hall C.

Friedrich Simmel und Aurore Dupin, researchers at the Technical University of Munich (TUM), have for the first time created artificial cell assemblies that can communicate with each other. The cells, separated by fatty membranes, exchange small chemical signaling molecules to trigger more complex reactions, such as the production of RNA and other proteins.

Freiburg researchers engineer cellular adhesion receptors that can be controlled with light

Plasmas can be found inside of stars, but they are also artificially created using special equipment in the laboratory. If a plasma comes in contact with a solid, such as the wall of the lab equipment, under certain circumstances the wall is changed fundamentally and permanently. A team from the Institute of Theoretical Physics and Astrophysics at Kiel University (CAU) has now discovered a surprising new effect, in which the electronic properties of the solid material, such as its electrical conductivity, can be changed in a controlled, extremely fast and reversible manner, by ion impact. Their results were recently published in the journal "Physical Review Letters".
