Pterostilbene, a molecule similar to resveratrol, as a potential treatment for obesity

In collaboration with the United States Department of Agriculture, researchers in the UPV/EHU’s ‘Nutrition and Obesity’ Group, which belongs to the Spanish Biomedical Research Centre in Physiopathology of Obesity and Nutrition of the Carlos III Institute of Health, have observed in animal models that pterostilbene reduces the build-up of body fat, which could reduce the risk of developing other diseases like diabetes. —> Read More Here

Archeologists Make Incredible Discoveries In Tunnel Sealed 2,000 Years Ago

MEXICO CITY (AP) — A years-long exploration of a tunnel sealed almost 2,000 years ago at the ancient city of Teotihuacan yielded thousands of relics and the discovery of three chambers that could hold more important finds, Mexican archaeologists said Wednesday.

Project leader Sergio Gomez said researchers recently reached the end of the 340-foot (103-meter) tunnel after meticulously working their way down its length, collecting relics from seeds to pottery to animal bones.

A large offering found near the entrance to the chambers, some 59 feet (18 meters) below the Temple of the Plumed Serpent, suggests they could be the tombs of the city’s elite.

“Because this is one of the most sacred places in all Teotihuacan, we believe that it could have been used for the rulers to … acquire divine endowment allowing them to rule on the surface,” Gomez said.

Unlike at other pre-Columbian ruins in Mexico, archaeologists have never found any remains believed to belong to Teotihuacan’s rulers. Such a discovery could help shine light on the leadership structure of the city, including whether rule was hereditary.

“We have not lost hope of finding that, and if they are there, they must be from someone very, very important,” Gomez said.

So far Gomez’s —> Read More Here

12 cities and 12 hundred participants gather in Rotterdam to talk deltas and climate change

Last month, concurrent with the UN Climate Summit, twelve C40 cities and more than 1200 people gathered in Rotterdam to attend the Second Deltas in Times of Climate Change Conference, supported by C40.

Representatives from Tokyo, Hong Kong, Jakarta, Ho Chi Minh City, Singapore, Melbourne, New Orleans, Copenhagen, London, Venice, and Washington DC joined their peers in Rotterdam for the 3-day international conference to discuss how to address climate change in delta cities under pressure as sea and river levels rise. In over 100 workshops, some designed by the C40 Connecting Delta City (CD) network members themselves, participants were given a good picture of the latest scientific insights and developments in the various delta areas around the world.

Rotterdam is recognized as an international leader in the field of climate adaptation. The city’s approach to leveraging more green solutions to protect residential areas rather than high-tech solutions was of particular interest to other delta cities. Mayor Aboutaleb of Rotterdam, who opened the conference, is convinced that his city can inspire other cities by sharing the knowledge gained here.

“We have in the city of Rotterdam I think wonderful examples to show to the world,” said Rotterdam Mayor Ahmed Aboutaleb. “That’s why the Delta —> Read More Here

What Is it Like for a Medical Student to Cut Open a Body for the First Time?


Answer by Jae Won Joh, sleepy medical dork

I simultaneously felt awe, fear, excitement, humility, cowardice, courage, frailty, strength, embarrassment, curiosity, sorrow, and joy.

This was only my second day of medical school, but there I was, in the basement, with a real human body in front of me, preparing with a group of four others to make the first incision of many into a being that was human but could not feel, could not move, could not see, could not scream.

Lift the tank covers. Elevate the body from the tank. Unzip the body bag. Gingerly remove the towel covering the body. Moment of stunned silence.

I cannot adequately describe the mental/emotional overload. There doesn’t exist a word in the English language for it: every neuron was firing frantically, and every emotion was in such high gear. Everything eventually melded into an unworldly sense of… calm? that I’d never quite experienced before.

Ready, set… incision.

The moment that scalpel blade pierced skin, I damn near drowned in a mental storm: how do I detach myself enough to continue cutting what was once a living human being, but remain humanly connected such that I can appropriately appreciate their incredible sacrifice?

Keep cutting. This incision —> Read More Here

Why Does a Mirror Reverse Things Horizontally but Not Vertically?

Answer by Tatsuo Tabata, Majored in experimental nuclear physics; worked in the field of radiation physics

The “mirror puzzle” is commonly stated: Why does a plane mirror reverse left and right, but not top and bottom? This question refers to the left-right reversal in the shape of the mirror image of an object as compared with the original object, i.e., the reversal of the left-right asymmetry viewed from two different coordinate systems, each of which is intrinsic to the object or its mirror image. The left-right reversal in this sense always happens in mirroring the object for which left and right can be defined, irrespective of the relative configuration of the object to the mirror. The reason can be explained as follows:

Mirroring reverses the direction perpendicular to the mirror surface. Thus, the mirror image of an asymmetric object becomes its enantiomorph (an example of enantiomorphic pairs is a pair of left and right hands). An enantiomorph is, or can be considered to have been, obtained by reversal in any single direction of an object (“orientation reversing” mentioned in Joshua Levy’s answer; also equivalent to “space inversion” or “parity operation” in physics, in which all the three directions are —> Read More Here
