In this video, watch how novel robotic insects developed by a team of Seoul National University and Harvard scientists can jump directly off water's surface. The robots emulate the natural locomotion of water strider insects, which skim on and jump off the surface of water. For more information, visit the PR link.
Boston’s pile reached a maximum of 75 feet—so big it was summited and skied by two Powder magazine writers (they said it smelled awful). And that is the other critical thing to know about Boston’s pile: Because one of the most major snowfalls occurred on a trash pickup day where cans were knocked over into the streets as plows went by, this pile was saturated with garbage.
In Buffalo, a “Snovember” lake effect blizzard dropped a stunning seven feet of snow on the city in a single storm. The city was immobilized when plows couldn’t clear the roads fast enough because they didn’t have anywhere to put the snow. Officials estimated that somewhere between 10,000 and 11,000 truckloads of snow were taken to this site near the city’s Central Terminal. Buffalo’s pile was estimated at one point to be five stories tall.
New findings hint that the brain has legions of assorted clocks, all tick-tocking at different rates. Some parts of the brain handle milliseconds and others keep track of decades. Some neural timers handle body movements; others monitor information streaming in from the senses. Some brain departments make timing predictions for the future, while timing of memories is handled elsewhere.
This diversity has led some scientists to focus on figuring out how the brain stitches together the results from its many clocks to reflect the outside world accurately. A deeper understanding of how the brain’s timekeepers work might also shed light on something much more profound: how the brain constructs its own reality. The brain sometimes squishes, expands or warps time, some studies suggest. Subtle timing slips have been linked to emotions, attention, drugs and disorders such as schizophrenia. Those tweaks hint at how the brain normally counts seconds and milliseconds.
The total antioxidant content of more than 3100 foods, beverages, spices, herbs and supplements used worldwide
Background: A plant-based diet protects against chronic oxidative stress-related diseases. Dietary plants contain variable chemical families and amounts of antioxidants. It has been hypothesized that plant antioxidants may contribute to the beneficial health effects of dietary plants. Our objective was to develop a comprehensive food database consisting of the total antioxidant content of typical foods as well as other dietary items such as traditional medicine plants, herbs and spices and dietary supplements. This database is intended for use in a wide range of nutritional research, from in vitro and cell and animal studies, to clinical trials and nutritional epidemiological studies.
Methods: We procured samples from countries worldwide and assayed the samples for their total antioxidant content using a modified version of the FRAP assay. Results and sample information (such as country of origin, product and/or brand name) were registered for each individual food sample and constitute the Antioxidant Food Table.
Results: The results demonstrate that there are several thousand-fold differences in antioxidant content of foods. Spices, herbs and supplements include the most antioxidant rich products in our study, some exceptionally high. Berries, fruits, nuts, chocolate, vegetables and products thereof constitute common foods and beverages with high antioxidant values.
Conclusions: This database is to our best knowledge the most comprehensive Antioxidant Food Database published and it shows that plant-based foods introduce significantly more antioxidants into human diet than non- plant foods. Because of the large variations observed between otherwise comparable food samples the study emphasizes the importance of using a comprehensive database combined with a detailed system for food registration in clinical and epidemiological studies. The present antioxidant database is therefore an essential research tool to further elucidate the potential health effects of phytochemical antioxidants in diet.
