When SEC is challenged, CEOs notice

In 2005, Siebel Systems, Inc., a California software company, challenged an enforcement action taken by the Security and Exchange Commission (SEC) that found the business had violated the Regulation Fair Disclosure (Reg FD)—a regulation implemented to prevent businesses from giving key analysts and investors insider information. The Siebel case went to the federal court, marking the only court...

A novel way to get to the excited states of exotic nuclei

An atomic nucleus assumes discrete energy levels when added energy excites that nucleus. These energy levels are the nucleus' unique fingerprint; no two nuclei have identical energy patterns. For exotic nuclei, which have unbalanced numbers of protons and neutrons and often only exist for a fraction of a second, researchers have devised a variety of methods to measure the energies of their excited...

Exposure therapy to feared foods may help kids with eating disorders

Whether you're afraid of dogs, needles or enclosed spaces, one of the most effective interventions for this type of anxiety disorder is exposure therapy in which you confront your fear in a safe environment. A new study finds that exposure therapy is also a promising treatment for adolescents with eating disorders. They found that exposure to feared foods -- such as candy bars and pizza -- helped...

A new type of photonic time crystal gives light a boost

Researchers have developed a way to create photonic time crystals and shown that these bizarre, artificial materials amplify the light that shines on them. These findings could lead to more efficient and robust wireless communications and significantly improved lasers.

Surprising science behind bumblebee superfood

It's the spines. New research shows that the spiny pollen from plants in the sunflower family (Asteraceae) both reduces infection of a common bee parasite by 81 -- 94% and markedly increases the production of queen bumble bees. The research provides much-needed food for thought in one of the most vexing problems facing biologists and ecologists: how to reverse the great die-off of the world's...

Juice mission to Jupiter testing—down to the wire

Preparing the Juice mission to Jupiter has involved testing for all kinds of contingencies, down to the smallest of scales. This microscopic view shows surface damage to a tiny silver interconnector after being exposed to erosive atomic oxygen known to be found surrounding Jupiter's moon Ganymede.

New research finds surprising science behind bumble bee superfood

It's the spines. This is the conclusion of two new papers, led by researchers at the University of Massachusetts Amherst, showing that the spiny pollen from plants in the sunflower family (Asteraceae) both reduces infection of a common bee parasite by 81-94% and markedly increases the production of queen bumble bees.
