We're bombarded with information at all times, so much that if we had to try and process it all times, we'd be paralyzed. Our cerebellum does information damage control by filtering out what changes. Evolution made it possible for us to conserve energy while still processing anomalies quickly.
Tom Hanks has appeared in many acting roles over the years, playing young and old, smart and simple. Yet we always recognize him as Tom Hanks.
Why? Is it his appearance? His mannerisms? The way he moves?
University of Washington researchers have demonstrated that it's possible for machine learning algorithms to capture the 'persona' and create a digital model of a well-photographed person like Tom Hanks from the vast number of images of them available on the Internet.
With enough visual data to mine, the algorithms can also animate the digital model of Tom Hanks to deliver speeches that the real actor never performed.
PHILADELPHIA, December 7, 2015 - The largest and fastest-growing segment of people with epilepsy are those age 60 and older. People with epilepsy face a number of related health challenges, including cognitive, physical and psychological disorders. But new research suggests other, less expected consequences on the aging process. Four studies presented at the American Epilepsy Society's (AES) 69th Annual Meeting explore the effects of epilepsy on the brain, providing insights that shed light on the long-term implications of life with epilepsy.
Greenland's glaciers are retreating quickly, and a new study shows in historical terms just how quickly: over the past century, at least twice as fast as any other time in the past 9,500 years. The study also provides new evidence for just how sensitive glaciers are to temperature, showing that they responded to past abrupt cooling and warming periods, some of which might have lasted only decades.
To track how glaciers grew and shrank over time, the scientists extracted sediment cores from a glacier-fed lake that provided the first continuous observation of glacier change in southeastern Greenland. They then compared the results to similar rare cores from Iceland and Canada's Baffin Island for a regional view.
The maple syrup that's tapped from the tree may not be as fresh as you think it is.
Sugar maple trees can store carbon from the atmosphere for several years in non-structural reserves as a buffer against disturbances such as droughts, hurricane damage, or attacks by insects. A new study shows that trees draw on this reserve when springtime sap begins to flow.
Thus, the sweet sap of maple trees integrates sugars produced during several growing seasons. The findings may provide new insights on how trees store and regulate the availability of nutrients.
Most men who receive penile prostheses are very satisfied with the implants, indicating that the intervention is a valid treatment for erectile dysfunction.
Ovarian cancer is a deadly disease, one that's hard to detect until it has progressed significantly. More than 75 percent of women diagnosed with ovarian cancer have metastasis at the time of diagnosis, resulting in a low five-year survival rate of less than 30 percent.
A large number of studies have shown that an increased body mass index (BMI) is associated with a greater risk for ovarian cancer with worse overall survival. More than 35 percent of women in the United States are obese, putting them at increased risk for the cancer.
People often think hippos are herbivores with big smiling faces. Every now and then, reports of a hippo of hunting down prey, eating a carcass, or stealing prey from a crocodile are heard, but they're typically considered 'aberrant' or 'unusual' behavior.
Some doctors may recommend that patients with the flu take acetaminophen, or paracetemol, to relieve their symptoms; however, a new randomized clinical trial found no benefits to the over-the-counter medication in terms of fighting the influenza virus or reducing patients' temperature or other symptoms.
The trial included adults between 18 and 65 years of age with confirmed influenza infections who were treated with the maximum recommended dose of paracetamol or placebo for five days. Participants were monitored for up to 14 days.
Carbon dioxide emissions have always been something of a guess because they rely on self-reported figures. The developed world has been transparent but it was only a few years ago that China admitted to under-counting its own emissions, telling a different tale than the pollution clouds that wafted into other countries did.
LAWRENCE -- As delegates from 195 nations meet in Paris to debate mankind's response to global climate change, scientists from the University of Kansas and Rothamsted Research in England today issue a study of a major crop pest that underlines how "climate is changing in more ways than just warming."
Their paper, appearing in Nature Climate Change, shows how large-scale climatic changes drive a coordinated rise and fall of numbers of aphids across Great Britain, even when individual aphid populations in that nation are separated by great distance.
HANOVER, N.H. - Two studies by Dartmouth researchers and their colleagues shed new light on mercury pollution in the waters of the northeastern United States.
The studies -- here and here -- appear in the journal Marine Chemistry. PDFs are available on request.
Designers of Christmas cards used fine art on their products to divert attention away from concerns that that the festival was becoming too commercialised, a University of Exeter academic has found.
While heart-warming pictures of animals or festive decorations on Christmas cards may bring joy throughout December, few would consider these greetings to have great aesthetic merit. But Victorians were able to send each other Christmas cards created by respected artists, made to counter anxiety that growing consumerism was destroying sentiment.
