The Price Revolution in Europe, the runaway inflation that occurred during the years between 1515 to 1650, has been attributed to the sudden influx of silver from Mexico and Peru after discovery of the New World, which led to the decline in the value of of silver, and the growth of the European population and therefore competition for goods, which drove up prices.

The El Niño-Southern Oscillation (ENSO) drives many of the catastrophic climate events that occur from one year to the next: floods, droughts, wildfires, and hurricanes. 

However, climate scientists do not yet know how ENSO will respond to climate change. A new multi-century reconstruction of ENSO variability, based on fossil corals from Papua New Guinea, reveals a century-long decline in the number of El Niño events starting in the mid-1500s. It is the first time such a shift in activity has been documented in either modern observations or past reconstructions.

This reduced activity coincided with the initiation of an unusually cool period in the Northern Hemisphere called the Little Ice Age (LIA), which continued on into the mid-1800s.

Astronomers have identified a body that is very probably a planet wandering through space -  without a parent star. This is the closest such object to oue Solar System,  a distance of about 100 light-years and its comparative proximity and the absence of a bright star very close to it have allowed the team to study its atmosphere in great detail. 

Free-floating planets are planetary-mass objects that roam through space without any ties to a star. Possible examples of such objects have been found before but without knowing their ages, it was not possible for astronomers to know whether they were really planets or brown dwarfs,  “failed” stars that lack the bulk to trigger the reactions that make stars shine.

In the Journal of Minimal Access Surgery, a case report details a 46-year-old physically fit female with a history of excessive bleeding and benign growths on her uterus. Her surgery was performed through a two inch-long incision in the belly button, the thinnest part of the abdomen, using the robotic arms in a "chopstick" fashion, said Dr. John R. Lue, Chief of the Medical College of Georgia Section of General Obstetrics and Gynecology at Georgia Health Sciences University, showing that the precision and three-dimensional view provided by robots can enable essentially scar-free surgery for some women needing hysterectomies

Tel Beth-Shemesh, an ancient village that resisted the aggressive expansion of neighboring Philistines, has been hiding an 11th century B.C. sacred compound. The complex is comprised of an elevated, massive circular stone structure and an intricately constructed building characterized by a row of three flat, large round stones.

How do you test the effects of weightlessness in space without risking lives and a lot of money?

Use a bed. People in bed with their heads 6° below the horizontal for long periods causes their bodies to react in similar ways to being weightless and so bedrest studies are being used to answer questions on how our bodies adapt to living in space and and even how our bodies adapt to growing old. Like Tang and pens that write upside down, findings from bedrest studies may apply directly to people on Earth.
