Up until now catching lightning in a bottle has been easier than reproducing a range of earthquakes in the laboratory, according to a team of seismologists who can now duplicate the range of fault slip modes found during earthquakes, quiet periods and slow earthquakes.

"We were never able to make slow stick slip happen in the laboratory," said Christopher Marone, professor of geosciences, Penn State. "Our ability to systematically control stick velocity starts with this paper."

A new study finds that a vegetarian diet likely led to a mutation that may make people more likely to get heart disease and colon cancer.

Using reference data from the 1000 Genomes Project, the team discovered that a mutation called rs66698963 in the FADS2 gene used for making long chain polyunsaturated fats like arachidonic acid is linked to inflammatory diseases like heart disease and colon cancer -- but only if they didn't follow a balanced diet to offset the risk.

That is better scientific methodology than every single International Agency for Research on Cancer monograph produced since 2009, will IARC call a vegetarian diet a carcinogen?(1)

A University of Guelph professor has uncovered the "secret" to staying strong as we age - superb fitness.

Geoff Power found elderly people who were elite athletes in their youth or later in life - and who still compete as masters athletes -- have much healthier muscles at the cellular level compared to those of non-athletes.

His research was published recently in the Journal of Applied Physiology.

The study compared world-class track and field athletes in their 80s with people of the same age who are living independently. There have been few such studies of aging and muscle weakening in masters athletes in this age group.

A study led by Olli Vapalahti, professor of zoonotic virology at the University of Helsinki, Finland, has found that small amounts of genetic material from the Zika virus can be detected from a blood sample taken from a pregnant woman even weeks after the acute rash caused by the infection has passed, when the development of brain damage in the fetus is underway. Severe brain abnormalities can be detected through neuroimaging already at this early stage, even before the development of the intracranial calcifications and microcephaly previously associated with Zika virus infections.

Tempe, Ariz. -- A lack of adequate nutrition is blamed as one of many possible causes for colony collapse disorder or CCD -- a mysterious syndrome that causes a honey bee colony to die. Parasites, pesticides, pathogens and environmental changes are also stressors believed responsible for the decline of honey bees.

Since bees are critical to the world's food supply, learning how bees cope with these stressors is critical to understanding honey bee health and performance.

In two new studies, researchers from Arizona State University's School of Life Sciences have discovered that the stress of short-term nutritional deprivation as larvae (baby bees) actually makes honey bees more resilient to starvation as adults.

So you think the gold in your ring or watch came from a mine in Africa or Australia? Well, think farther away. Much, much farther.

Michigan State University researchers, working with colleagues from Technical University Darmstadt in Germany, are zeroing in on the answer to one of science's most puzzling questions: Where did heavy elements, such as gold, originate?

Currently there are two candidates, neither of which are located on Earth - a supernova, a massive star that, in its old age, collapsed and then catastrophically exploded under its own weight; or a neutron-star merger, in which two of these small yet incredibly massive stars come together and spew out huge amounts of stellar debris.

Spanish researchers have analysed how the sodium lost through sweat during a marathon influences the maintenance of stable and physiologically sound conditions that allow the body to carry out its functions. Excessive electrolyte loss may lead to a medical problem known as hyponatraemia.

For years, scientists have emphasised the importance of staying properly hydrated during exercise. Maintaining the body's sodium levels has become a key priority for the success of elite athletes and enthusiasts alike.

The amount of sweat that is lost during the majority of athletic activities (football, basketball, volleyball) is relatively low due to the duration of these sports.

Key opinions leaders in the field of haematopoetic stem cell transplantation (HSCT) will address the role of Cyclophosphamide, an anti-cancer chemotherapy drug, during the 42nd Annual Meeting of the European Society for Blood and Marrow Transplantation (EBMT) that will welcome more than 4,500 delegates in the host city of Valencia, Spain from the 3rd to the 6th of April 2016.

Allogeneic bone marrow or stem cell transplantation is a curative treatment for many patients with yet incurable blood cancers. One major limitation of this therapy is the need to find a fully matched or compatible donor. Unfortunately, only a minority of the patients can have access to such fully matched donors.

In a previous How-To Guide I demonstrated how to blink a Snap Circuits LED with the Kano Computer (blinking an LED is the “Hello World!” of hardware hacking) and in this guide I’ll demonstrate how to drive a variable speed fan with Snap Circuits and the Kano Computer. I’ll actually use the same Scratch program that I used to blink the LED to control the speed of the motor. When I pressed the up arrow on the Kano keyboard, the LED blinked faster and faster. Conversely, when I pressed the down arrow the LED flashed slower and slower.

When Tootsie Roll chairman and CEO Melvin Gordon died unexpectedly on Jan. 20, 2015, the firm's value saw an immediate 7 percent increase, which was equivalent to about $140 million. Craig Crossland, an assistant professor of management at the University of Notre Dame's Mendoza College of Business, and his research colleagues examined 240 sudden and unexpected CEO deaths like Gordon's to determine how shareholders' perceptions of CEO significance have changed over time. They found that market reactions to these events in U.S. public firms have increased markedly between 1950 and 2009.

"Our results indicate that shareholders act in ways consistent with the belief that CEOs have become increasingly more influential in recent decades," Crossland said.
