Johns Hopkins engineers have invented a lab device to give cancer researchers an unprecedented microscopic look at metastasis, the complex way that tumor cells spread through the body, causing more than 90 percent of cancer-related deaths. —> Read More Here
Scientists have long speculated as to why animal species didn’t flourish sooner, once sufficient oxygen covered the Earth’s surface. Animals began to prosper at the end of the Proterozoic period — but what about the billion-year stretch before that, when most researchers think there also was plenty of oxygen?Yale University researcher Noah Planavsky and his colleagues found that oxygen levels during the ‘boring billion’ period were only 0.1 percent of what they are today. —> Read More Here
New research suggests that insomnia is a major contributor to deaths caused by motor vehicle crashes and other unintentional fatal injuries. The results underscore the importance of the ‘Sleep Well, Be Well’ campaign of the National Healthy Sleep Awareness Project. —> Read More Here
Nearly one out of four older Americans say that either they or a family member have experienced excessive or unwanted medical treatment, according to the latest issue of The Gerontological Society of America’s Public Policy & Aging Report, which goes on to show that Americans strongly support holding doctors accountable when they fail to honor patients’ end-of-life health care wishes. —> Read More Here
The MAX IV facility, currently under construction in Lund, Sweden, is the first of a new generation of storage-ring-based synchrotron light sources which employ a multibend achromat lattice to reach emittances in the few hundred pm rad range in a circumference of a few hundred meters. —> Read More Here

People infected with Ebola vary greatly in how severe their symptoms are. The majority die, but some develop only very mild symptoms, and it is even possible that some have no symptoms at all. Now, a new study in mice suggests that genetics plays a role in how each body reacts to the same Ebola virus.
To study the relationship between genes and the virus, researchers used a group of mice that were bred to have high genetic diversity, as opposed to the typical laboratory mice, which are produced by many generations of inbreeding and are therefore extremely similar. Normally, classic lab mice don’t develop the symptoms of Ebola that are seen in people, even though the animals do die from a lethal dose of the virus.
In the study, among the genetically diverse mice, the researchers saw a full range of Ebola symptoms when they infected the animals with the virus. Some mice were resistant to infection, some showed symptoms but survived, and some were similar to classical lab mice (they died without showing bleeding symptoms). About 40 percent of the animals developed blood and liver —> Read More Here
According to a new study led by Dr Brian Monteleone of the Woods Hole Oceanographic Institution, Earth’s oceans have likely existed since the planet’s formation. “Our oceans were always here. We didn’t get them from a late process, as was previously thought,” said Dr Adam Sarafian, a researcher with the Woods Hole Oceanographic Institution and [...] —> Read More Here

“I am enough the way I am.”
This popular, self-affirming mantra and others like it grant power to those in need of an extra boost of motivation. A new meta-analysis published on the Society for Personality and Social Psychology’s Character & Context’s blog confirms that self-affirmations can help us all achieve higher in many areas our lives — especially when it comes to our health.
Tracy Epton of the University of Manchester collected and analyzed 41 studies involving self-affirmation practices, which include anything that helps people recognize their inherent value as individuals. She and her team found that overall, self-affirmation helped “improve message acceptance, intentions, and behavior.”
Specifically, the self-affirmations had a positive impact on improving health behaviors and lifestyle habits, particularly during a period of illness. “As self-affirmation works by reducing defensive responding when people feel threatened,” wrote Epton. “It could be that self-affirmation is most effective on more proximal health risks as they are perceived as more threatening (e.g., they are perceived as more vivid and relevant) than more distal risks.”
Interestingly, the impact of this self-affirming behavior doesn’t change with the gender or occupation of the person — or even their socioeconomic circumstances: Last year, a study —> Read More Here
