PROVIDENCE, R.I. [Brown University] — The surface of Mercury crackled with volcanic explosions for extended periods of the planet's history, according to a new analysis led by researchers at Brown University. The findings are surprising considering Mercury wasn't supposed to have explosive volcanism in the first place, and they could have implications for understanding how Mercury formed.

Despite high rates of contraceptive use, unwanted pregnancies resulting in terminations remain high among young women.

In an article in the April issue of the Australian and New Zealand Journal of Public Health, Danielle Mazza from Monash University, and colleagues, examine the paradox of high rates of contraceptive use, over the counter availability of emergency contraception and unplanned pregnancy.

"The emergency contraceptive pill has been available to women for over-the-counter purchase since 2004," Professor Mazza said.

"Together with high rates of contraceptive use, this should result in lower rates of unplanned pregnancies for Australian women, but it has not.

BUFFALO, N.Y. – Chemotherapeutic drugs excel at fighting cancer, but they're not so efficient at getting where they need to go.

They often interact with blood, bone marrow and other healthy bodily systems.

A team of researchers from the Center for Imaging Science at the Johns Hopkins University and the CMLA of the École Normale Supérieure Cachan have demonstrated new algorithmic technologies for the parametric representation of human shape and form. Coupled with advanced imaging technologies, this presents opportunities for tracking soft-tissue deformations associated with cardiovascular studies, radiation treatment planning in Oncology, and neurodegenerative brain illnesses.

CAMBRIDGE, Mass-- The electrochemical reactions inside the porous electrodes of batteries and fuel cells have been described by theorists, but never measured directly. Now, a team at MIT has figured out a way to measure the fundamental charge transfer rate — finding some significant surprises.

The study found that the Butler-Volmer (BV) equation, usually used to describe reaction rates in electrodes, is inaccurate, especially at higher voltage levels. Instead, a different approach, called Marcus-Hush-Chidsey charge-transfer theory, provides more realistic results — revealing that the limiting step of these reactions is not what had been thought.

Russia has control over energy supplies and distribution systems in Ukraine and that means they control energy supplies in Western Europe.

It's made a lot of Russians rich and prevents Europe from taking any meaningful stance on Russian aggression in Crimea. Solar power subsidies are not going to be much help if Russia shuts off the power.
