When you were younger, were you ever scared to lie because you thought your nose would grow like Pinocchio’s? It turns out that there might actually be a little bit of truth in this. Thermography is a technique based on body temperature that usually uses a thermographic camera to measure body heat. It was found that when a person is feeling a certain emotion, lying, or even doing a specific kind of dance, that a certain area of their body will either lose or gain heat. (Read more…)

We humans are the possibly the greatest evolutionary force on earth. We have caused entire species to become extinct, created new species, and changed the landscape of entire countries. A new study has found another change. In comparing the skull sizes of small mammals in both a city and rural environment, Dr. Snell-Rood found the skulls of the city animals to be bigger by 6%. She suggested that the change was due to the immense change in the environment she studied: Minnesota. (Read more…)

Diabetes: Avoiding the Needle

Researchers at North Carolina State University and the University of North Carolina at Chapel Hill believe they may have found a away for diabetics to painlessly give themselves insulin using a small ultrasound device. It also allows diabetics to go days without injecting as opposed to several times a day. It works by injecting nano-particles either coated with a positive or negative solution filled with insulin that is slowly released. The charged coating keeps the particles from dispersing throughout the body which creates a dose of insulin waiting to be pulled into the bloodstream. (Read more…)

Carbon Dioxide Could Warm Us For Centuries

According to a Princeton University-led research, even if we all suddenly stopped producing carbon dioxide emissions, the gas already in our atmosphere could continue heating up the planet for hundreds of years. The researchers simulated Earth if all emissions stopped and found that after twenty years 40% of the emissions had been absorbed by oceans and landmasses. After 1,000 years, 80% of the emissions had been absorbed. The simulation showed a temperature increase of .37 degrees Celsius. While it sounds insignificant, small temperature increase could interfere with the climate system on Earth. (Read more…)

Power Walking, Literally

A company called Pavegan has figured out how to harness energy from individuals just by walking! Simply walking on one of Pavegen’s tiles will cause them to light up like a firefly. While each tile generally each tile only generates four to eight watts of power, putting a large concentration of them in a place with lots of foot traffic and enough energy can be made to power a string of street lights or charge thousands of cell phones.

No Pollution, No Ducks

Lough Neagh, a lake larger than 380 square kilometers, has been a major wintering spot for ducks migrating. But from 2000 to 2009, the amount of ducks at the lake during the winter dropped by 63 percent. In the 1970’s, the lake was richly polluted with run-off, but recent clean up efforts have begun to have negative effects. Researchers believe the change in amount of run-off has caused the number of crustaceans and bugs to decrease. (Read more…)

The Nature of People, the Future, and Nature

It has recently been suggested that people who have been exposed to nature generally think long-term when making decisions. Researchers tested their hypothesis by having a group of 43 people walk through a forest and a developed part of Amsterdam. The participants exposed to nature tend to discount the future less and reported to be in a better mood. (Read more…)
