Airlines may allow use of mobile devices during lift-off

Have you ever wondered what would happen if you kept your electronic device on during takeoff or landing? It’s a hassle to have to turn our electronic devices off, but pilots and flight attendants are adamant about reducing electronic device activity during take off. With our increased dependence and closeness to MP3 players, texting, web surfing, and a myriad of other functionalities in mobile devices, these airline policies are wearing passengers’ patience thin.

Hope is found even in flat-lined EEG

Most think of a coma as a state of limbo between life and death. The word “coma” conjures up an image of a seemingly lifeless patient, hooked up to a variety of monitoring devices. The most recognizable of these devices is the EEG. The EEG — or electroencephalogram — measures the brain activity of the patient.

Does dog food alleviate chemo side effects?

In a world where so much has already been discovered, it is common for people to overlook the true potential of everyday chemicals. Similar to how Mustard Gas was used in World War I and then harnessed to become a potential chemotherapeutic agent, many everyday chemical substances possess great potential.

Functional mechanical gears found in insect

As creative as our large human brains make us, the adaptive forces of nature often outsmart us. After all, it was these forces that pushed us to develop such meaty neo-cortices in the first place and made us the smartest species on earth.

Harvard creates matter, light sabers

Until recently, the concept of squirrels dueling with light sabers was a complete work of science fiction and loopy Internet humor. However, now, a team of Harvard and MIT scientists are claiming to have created of a new form of matter — from light. They make an analogy between the newly created “photonic molecules” and a light saber. And they aren’t joking.

Scientists discover genetic basis for handedness

The distribution of right handed and left handed people in the world seem to be random. Different family members can write with either hand, and there are a few of those who can switch between both hands. In most cases, it doesn’t seem to be a trained practice and it just comes naturally for each individual. However, recently, genes that are linked to the orientation of internal organs during embryogenesis were found to play a role in the development of handedness.

Merlin protein prevents tumors

Tumors, both cancerous and noncancerous, can arise when cellular pathways that control cell proliferation and tissue growth go awry. Many ongoing research efforts are underway to identify the crucial genetic underpinning of such pathways.

Largest earthquake ever recorded in Asia

“Not another earthquake!” I am sure that this is the thought that most Japanese citizens would jump to if they heard that one of the absolute largest earthquakes ever recorded occurred earlier this year right on the Japanese sea border. The magnitude 8.3 earthquake rattled the earth below the Sea of Okhotsk, an area enclosed by the Russian, Chinese, and Japanese borders.

JHU uses light to restart the heart

Electrical stimulation of the heart is a common phenomenon. If you are CPR/AED certified, you’ve practiced saving someone’s life using a defibrillator. If you know anyone with a heart problem, chances are they have a pacemaker or have talked to their doctor about getting one. Both defibrillators and electrodes use direct electrical stimulation to correct cardiac arrhythmias.

A mass of students use wifi to get iOS7

If you own a Twitter, you certainly know what day it is today. It’s #iOS7 day, of course. After weeks of anticipation, Apple has finally released iOS 7 to the masses. What is new in iOS 7, and what does it mean for you?

NuSTAR program finds data in black holes

The celestial bodies found on the beaches of southern California have only a secondary priority for researchers at Caltech’s NuSTAR program. The Nuclear Spectroscopic Telescope Array, or NuSTAR, is an X-ray telescope designed to focus X-rays from the universe to survey for black holes.
