Nature. Stanford engineers develop a Star Trek-style tricorder to detect early stage cancer. Star Trek popularized the concept of the tricorder — a handheld device that can scan a person, object, or atmosphere and report on its health or makeup.

Stanford engineers develop a Star Trek-style tricorder to detect early stage cancer

Now, a team of Stanford electrical engineers have taken a giant leap for mankind toward a real device that can do just that. The team’s research theorizes that microwaves and ultrasound can work together in a portable device to detect hidden objects, be they plastic explosives or deadly tumors. The research, led by Assistant Professor Amin Arbabian and Research Professor Pierre Khuri-Yakub, was primarily motivated by military technology developed to locate plastic explosives that would evade metal detectors.

The team says the same technology could have medical applications, with a potential to detect early stage cancers.

Although YouTube has something of a reputation as a repository for the inane mental diarrhea of stunted man-children injuring each other for cheap laughs or shrill teenage drama queens shrieking like harpies over the latest bland, interchangeable lump passing as the epitome of masculine beauty, many others thankfully take advantage of its services as a portal to share their knowledge and educate viewers.

While few of the scientific offerings formally follow the scientific method or test an explicitly stated hypothesis, even those videos veering more towards demonstrating various principles, theories, and laws still offer visitors a chance to learn something about how the world around them operates. By this point, it should go without saying that many of the following videos contain procedures that may be dangerous to perform at home or without the proper equipment and/or training. Please do not duplicate any of these experiments unless assured that they are entirely safe for amateurs.

Exploration. The fastest accelerating electric vehicle in the world hits 100 km/h in 1.779 seconds. A team of students from the University of Stuttgart just designed, built and raced what could be the fastest accelerating electric vehicle in the world.

The fastest accelerating electric vehicle in the world hits 100 km/h in 1.779 seconds

During carefully monitored tests, the student-designed E0711-6 electric car successfully managed to accelerate from 0-100km/h in a mind-blowing 1.779 seconds. The team is anxiously awaiting confirmation of a new record from the Guinness Book of World Records. The E0711-6 was designed and manufactured by a team of students—dubbed the Green Team—who participate in an annual project to create an open, single-seater formula electric race car.

This year’s vehicle—the sixth incarnation since the project started—weighs in at just 165 kg (363 lb) and is built entirely from parts either constructed from scratch, or modified by, the student team.

Sir Isaac Newton PRS MP (/ˈnjuːtən/;[8] 25 December 1642 – 20 March 1726/7[1]) was an English physicist and mathematician (described in his own day as a "natural philosopher") who is widely recognised as one of the most influential scientists of all time and as a key figure in the scientific revolution.

Isaac Newton

His book Philosophiæ Naturalis Principia Mathematica ("Mathematical Principles of Natural Philosophy"), first published in 1687, laid the foundations for classical mechanics. Newton made seminal contributions to optics, and he shares credit with Gottfried Leibniz for the development of calculus. Science! Physics. Pharmacognosy. Pharmacognosy is the study of medicines derived from natural sources.


The American Society of Pharmacognosy defines pharmacognosy as "the study of the physical, chemical, biochemical and biological properties of drugs, drug substances or potential drugs or drug substances of natural origin as well as the search for new drugs from natural sources. "[1] It is also defined as the study of crude drugs. Introduction[edit] The word "pharmacognosy" is derived from the Greek words φάρμακον pharmakon (drug), and γνῶσις gnosis (knowledge).

More galleries. Dream. Dreams mainly occur in the rapid-eye movement (REM) stage of sleep—when brain activity is high and resembles that of being awake.


REM sleep is revealed by continuous movements of the eyes during sleep. At times, dreams may occur during other stages of sleep. However, these dreams tend to be much less vivid or memorable.[3] The length of a dream can vary; they may last for a few seconds, or approximately 20–30 minutes.[3] People are more likely to remember the dream if they are awakened during the REM phase. The average person has three to five dreams per night, but some may have up to seven dreams in one night.[4] The dreams tend to last longer as the night progresses. - Science News, Technology, Physics, Nanotechnology, Space ...
