NASA Begins America’s New Moon to Mars Exploration Approach in 2018

NASA welcomed a new administrator, Jim Bridenstine, deputy administrator, Jim Morhard, and chief financial officer, Jeff DeWit, in 2018. Their focus is on firmly establishing the groundwork to send Americans back to the Moon sustainably, with plans to use the agency’s lunar experience to prepare to send astronauts to Mars.

Pressure tuned magnetism paves the way for novel electronic devices

Using very sensitive magnetic probes, an international team of researchers has found surprising evidence that magnetism which emerges at the interfaces between non-magnetic oxide thin layers can be easily tuned by exerting tiny mechanical forces. This discovery provides a new and unexpected handle to control magnetism, thus enabling denser magnetic memory, and opens new and unexpected routes for developing novel oxide-based spintronic devices.

Advancing the description of 'mysterious' water to improve drug design

Interactions with water dominate how drug molecules bind to targets, but it's tricky to model these interactions, limiting the accuracy of drug design. Scientists have now described a novel approach to building a new description of water (known as a force field) and demonstrating its accuracy.

Pressure tuned magnetism paves the way for novel electronic devices

Advances in the technology of material growth allow fabricating sandwiches of materials with atomic precision. The interface between the two materials can sometimes exhibit physical phenomena which do not exist in both parent materials. For example, a magnetic interface found between two non-magnetic materials. A new discovery, published today in Nature Physics, shows a new way of controlling this emergent magnetism which may be the basis for new types of magnetic electronic devices.

Hiding images and information in plain sight

What is real is not always as it appears. Researchers have found a way to hide information on materials and only make it visible to a person using the right tech.

New type of low-energy nanolaser that shines in all directions

Researchers have developed a new type of low-energy, nanoscale laser that shines in all directions. The key to its omnidirectional light emission is the introduction of something that is usually highly undesirable in nanotechnology: irregularities in the materials. The researchers foresee a vast range of potential applications, but first they hope their fundamental work will inspire others to further improve it and deepen the understanding.

Pedestrians keep a 75 cm comfort zone to prevent collisions

Pedestrians are constantly avoiding collisions with oncoming people. Meters in advance they unconsciously change their walkway to pass each other. Physicists at Eindhoven University of Technology in collaboration with American and Italian researchers analyzed 5 million pedestrian movements at the Eindhoven train station. They discovered that people want to keep an average distance of at least 75 cm. Professor Federico Toschi and postdoc Alessandro Corbetta publish these results today in the journal Physical Review E.

NASA Sends CubeSats to Space on First Dedicated Launch with US Partner Rocket Lab

A series of new CubeSats now are in space, conducting a variety of scientific investigations and technology demonstrations, following launch Sunday of Rocket Lab’s first mission for NASA under a Venture Class Launch Services (VCLS) contract.

Scientists invent easier, cheaper way to measure gravity

The world has one official kilogram against which all other country's kilograms are measured and scales calibrated.

Adhesives for biomedical applications can be detached with light

Pulling off a little plastic bandage may soon get a lot less painful. Researchers have developed a new type of adhesive that can strongly adhere wet materials -- such as hydrogel and living tissue -- and be easily detached with a specific frequency of light. The adhesives could be used to attach and painlessly detach wound dressings, transdermal drug delivery devices, and wearable robotics.
