German researchers at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM), together with their colleagues from the Max Planck Institute for Nuclear Physics in Heidelberg and the GSI Helmholtz Center for Heavy Ion Research in Darmstadt, have observed spin quantum-jumps with a single trapped proton for the first time. The fact that they have managed to procure this elusive data means that they have overtaken their research competitors at the elite Harvard University and are now the global leaders in this field.

Feed SubscriptionProblems Without Passports: Scientific Research Diving at USC Dornsife–Looking Ahead
Last week, my colleagues and I wrapped up our second annual Maymester course to Guam and Palau.While the course participants returned to Los Angeles, I stayed behind on the island of Guam to catch up with old friends and colleagues, and to begin sketching out a rough draft of next year’s scientific course content.

Eshel Ben-Jacob is interested not only in the genomes of the bacteria he studies but also in their personalities. He compares many to Hollywood celebrities. “On the one hand, we admire them, but on the other hand, we think that they are stupid,” says Ben-Jacob, a professor of physics at Tel Aviv University in Israel.

By sending out a tweet for action, businesses can connect with their customers in a fun way, while rewarding their most loyal and enthusiastic customers with lucrative prizes. When JetBlue social media strategist Morgan Johnston and his colleagues were called to a meeting to discuss how to increase awareness of the @JetBlueCheeps Twitter account, they opened up the discussion to their Twitter followers—asking their opinions on what should be done differently

Quantum mechanics is the most successful description of nature known to humans, yet it has many bizarre implications for our understanding of the world. There are phenomena of superposition (objects being in two places at the same time), entanglement (correlations that exceed any classical correlations) and nonlocality (apparent ability for information to travel instantaneously across vast distances)

Tasmanian devils are losing a hellish battle: A contagious cancer--called devil facial tumor disease--is spreading across their island home, their last bastion of safety from human encroachment. Populations of this carnivorous marsupial have declined in parts of Tasmania by as much as 95 percent, and the species is now officially endangered

What distinguishes a fling that ends in tears from long-term love? Past research suggests that the most successful couples share common interests, values and personality traits. Now new research published in Psychological Science proposes that the simplest words lovebirds use to speak to each other also make a difference--both in determining how attracted they are and how likely they are to stay together

For most of the past century the scientific consensus held that the adult human brain did not produce any new neurons. Researchers overturned that theory in the 1990s, but what role new neurons played in the adult human brain remained a mystery. Recent work now sug

(PhysOrg.com) -- Rice University researchers have created a method to measure the axial rotation of tiny rods. The technique detailed in a paper by Sibani Lisa Biswal and her colleagues appears this month in the journal Physical Review Letters.

Nuclear magnetic resonance (NMR) is a powerful tool for chemical analysis and, in the form of magnetic resonance imaging (MRI), an indispensable technique for medical diagnosis. But its uses have been limited by the need for strong magnetic fields and big, expensive, superconducting magnets. Now Berkeley Lab scientists and their colleagues have demonstrated that they can do NMR in a zero magnetic field without using any magnets at all.

(PhysOrg.com) -- Researchers at Yale University have succeeded in building a new kind of laser based on the way brightly colored birds show their colors. Building on the new approach to creating laser beams, whereby holes are drilled in a material in such a way as to trap light inside for a long enough period of time to create the laser light they are after, researchers Hui Cao, Heeso Noh and their colleagues describe in a paper they've published in Physical Review Letters, how they've emulated the way birds use air holes to display their colors.

(PhysOrg.com) -- Spintronics also known as magnetoelectronics may replace electronics as the medium of choice for computer memory. The discovery of a mechanism that produces permanent magnets at room temperature, without any external influence, may soon improve the design of spintronic devices. Takumi Ohtsuki from the RIKEN SPring-8 Center, Harima and his colleagues in Japan, made the discovery in a class of material called a dilute ferromagnetic oxide.
