In a new effort to understand magnetism, a group of Hamburg Centre for Ultrafast Imaging researchers created “mimic” magnets by controlling quantum matter waves made of rubidium atoms. Under well-defined conditions made possible with the help of supercomputers, these artificially created magnets can be studied with clarity and then give a fresh perspective on long-standing riddles.

A massive impact on the moon about 4 billion years ago left a 2,500-mile crater, among the largest known craters in the solar system. Smaller subsequent impacts left craters within that crater. Comparing the spectra of light reflected from the peaks of those craters may yield clues to the composition of the moon’s lower crust and mantle—and would have implications for models of how the moon formed.
Funded by prominent Silicon Valley investors and Microsoft founder Bill Gates, Hampton Creek Foods seeks to disrupt a global egg industry that backers say wastes energy, pollutes the environment, causes disease outbreaks and confines chickens to tiny spaces. The company, which just started selling a mayonnaise made without eggs, is part of a new generation of so-called food-tech ventures that aim to change the way we eat.
NASA's Curiosity rover has uncovered signs of an ancient freshwater lake on Mars that may have teemed with tiny organisms for tens of millions of years, far longer than scientists had imagined, new research suggests. The watering hole near the Martian equator existed about 3.5 billion years ago. Scientists say it was neither salty nor acidic, and contained nutrients—a perfect spot to support microbes.
As embryonic tissue develops, cells push and pull on each other, and they must do so correctly for the tissue to develop properly. Now scientists at Harvard Univ. have devised the first method to measure these tiny forces in 3-D tissues and living embryos. The method, which involves injecting tiny oil droplets, could lead to new tools to diagnose cancer, hypertension, connective tissue diseases and more.
Carbon nanotubes carry plasmonic signals in the terahertz range of the electromagnetic spectrum, but only if they’re metallic by nature or doped. In new research, the Rice Univ. laboratory of physicist Junichiro Kono disproved previous theories that dominant terahertz response comes from narrow-gap semiconducting nanotubes.
For nearly 50 years, contact lenses have been proposed as a means of ocular drug delivery that may someday replace eye drops, but achieving controlled drug release has been a significant challenge. Researchers in Massachusetts have made an advance in this direction with the development of a drug-eluting contact lens designed for prolonged delivery glaucoma medication.
Students may soon be able to touch some of the theoretical concepts they are taught in their physics classes thanks to a new idea devised by a group of researchers in England. In just eight hours and at the cost of around 15 euros, they were able to use a commercially available 3-D printer to create their own object based on a mathematical model that described how forest fires can be started and how they eventually spread over time.
Researchers in Lyon, a French city famed for its cuisine, have discovered a quick-cook recipe for copious volumes of hydrogen that involves water, rock, aluminum oxide and extreme pressure. The breakthrough suggests a better way of producing the hydrogen that propels rockets and energizes battery-like fuel cells.
The most tweeted peer-reviewed articles published between 2010 and 2012, and the trends associated with their social media success, have been identified by researchers in Canada. With colleagues in the United States, U.K. and Germany, they took 1.4 million articles held in the PubMed and Web of Science databases and determined how many times they appeared on Twitter.
Researchers in Singapore and at IBM Research in California have discovered a new, potentially life-saving application for polyethylene terephthalate (PET), which is widely used to make plastic bottles. They have successfully converted PET into a non-toxic biocompatible material with superior fungal killing properties. This could help prevent and treat various fungus-induced diseases such as keratitis.
A connected vehicle network, with vehicles exchanging information with the highway infrastructure and other vehicles using wireless communications, could improve traffic safety, mobility and environmental impacts. Southwest Research Institute, which has considerable expertise in intelligent vehicle development, is now serving as an official Connected Vehicle Affiliated Test Bed for this technology.
Medicated adhesive patches have become a preferred method of delivery for everything from nicotine to hormones to motion sickness medication. Drexel Univ. researchers are trying to expand the possibilities of this system, which is called transdermal delivery, with the help of a cleverly designed delivery vehicle and an ultrasonic "push," or pressure from sound waves.
An ultrasonic microscope emits a high frequency sound at an object, and the reflected sound captured by its lens is converted into a 2-D image of the object under scrutiny. Prof. Naohiro Hozumi in Japan is developing the technology to monitor living tissue and cell specimens for medical purposes.
In one of the biggest advances against leukemia and other blood cancers in many years, doctors are reporting unprecedented success by using gene therapy to transform patients' blood cells into soldiers that seek and destroy cancer. A few patients with one type of leukemia were given this one-time, experimental therapy several years ago and some remain cancer-free today.
Autism spectrum disorder (ASD) is diagnosed when individuals exhibit characteristic behaviors that include repetitive actions, decreased social interactions and impaired communication. Curiously, many individuals with ASD also suffer from gastrointestinal (GI) issues, such as abdominal cramps and constipation. Using the co-occurrence of brain and gut problems in ASD as their guide, researchers are investigating a new therapy.
