Using a virtual pendulum and its real-world counterpart, scientists at the University of Illinois have created the first mixed reality state in a physical system. Through bi-directional instantaneous coupling, each pendulum “sensed” the other, their motions became correlated, and the two began swinging as one.

“In a mixed reality state there is no clear boundary between the real system and the virtual system,” said U. of I. physicist Alfred Hubler. “The line blurs between what’s real and what isn’t.”

In the experiment, Hubler and graduate student Vadas Gintautas connected a mechanical pendulum to a virtual one that moved under time-tested equations of motion. The researchers sent data about the real pendulum to the virtual one, and sent information about the virtual pendulum to a motor that influenced motion of the real pendulum.

Video games such as Second Life give users the freedom to create characters in the digital domain that look and seem more human than ever before but while they can have your hair or your hazel eyes, it's still just a pretty face.

A group of researchers from Rensselaer Polytechnic Institute is working to change that.

They are engineering characters with the capacity to have beliefs and to reason about the beliefs of others. The characters will be able to predict and manipulate the behavior of even human players, with whom they interact in the real world, according to the team.

New research suggests that humans are not as fooled as they seem when viewing visual illusions.

Ben-Gurion University of the Negev Psychologist Tzvi Ganel, writing in the March issue of Psychological Science, says we process images in two very distinct ways. He and his colleagues presented research participants with the “Ponzo” illusion, an image common in psychological research that makes two objects that are similar in length appear drastically different. They then hooked participants’ index finger and thumb to computerized position tracking equipment and asked them to grasp the objects with their fingers.

"I’ll take a burger and fries, hold the fluoride.” Fluoride? Serious scientists, who look, find fluoride in the darnedest places. Researchers from the University of Indiana School of Dentistry report in the scientific journal “Community Dentistry and Oral Epidemiology” that McDonald’s French fries deliver more than guilty pleasure. Your teeth bite into 0.13 milligrams fluoride along with that small portion of McDonald’s fries that goes upward to 0.38 mg in the supersize. So why do we need to know that? Because of fluoridation, where water engineers purposely add fluoride to water supplies to reduce tooth decay, and the billion dollar fluoride products industry, many Americans are fluoride over-dosed.

Cells are coded with several programs for self-destruction. Many cells die peacefully. Others cause a ruckus on their way out.

Some programmed cell death pathways simply and quietly remove unwanted cells, noted a team of University of Washington (UW) researchers who study the mechanisms of cell destruction.

Then there is the alarm-ringing death of a potentially dangerous cell, such as a cell infected with Salmonella, they added. These dying cells spill chemical signals and get a protective response. The resulting inflammation, which the body launches in self-defense, can at times backfire and damage vital tissues.


This schematic shows the cell death pathway called pyroptosis, Greek for going down in flames. When activated by a toxin or an infection, the enzyme caspase-1 initiates several reactions inside of the cell, some of which lead to DNA damage, others to the release of chemical distress signals called cytokines, and others to the formation in the cell membrane of tiny pores that let water flood in until the cell swells, bursts and spills its contents.
