Following my Ten Commandments for Tech Companies – which changed their behavior not one whit – I offer these shalt-nots for US airlines.

James Hansen, a former head of NASA’s Goddard Institute for Space Studies who was one of the first scientists to raise concerns about global climate change, spoke at MIT Tuesday in the biennial David J. Rose Lecture, sponsored by the Department of Nuclear Science and Engineering (NSE).

 Hansen came to prominence in the late 1980s, when he first testified before Congress about the perils of accumulating carbon dioxide in the atmosphere.

The two heaviest naturally occurring radioactive elements (by atomic weight) on the earth are Uranium and Thorium.  Uranium is used as a fuel in modern commercial nuclear power reactors for electricity generation.  A lesser known fact is that thorium could also be used as a nuclear fuel .  Naturally occurring thorium is not fissile and so not able to undergo nuclear fission (separation) and as such it takes an initial nuclear reaction to enable this process.

Surveying news headlines in recent years, it seems that cheating is rampant.

In the athletic arena, Lance Armstrong was stripped of his seven Tour de France titles for using performance-enhancing drugs.

In business, some of the world’s largest banks have paid nearly $200 billion – the equivalent of the GDP of New Zealand – in fines over the past six years for cheating.

A new wearable device turns the user’s thumbnail into a miniature wireless track pad, which could let users control wireless devices when their hands are full or enable subtle communication in circumstances that require it, such as sending a quick text to a child while attending an important meeting.

Next week at the Association for Computing Machinery’s Computer-Human Interaction conference in Seoul, MIT researchers will describe the prototype of NailO.

Using technology like tablets in schools has turned into a heated political debate. Los Angeles infamously spent $1.3 billion on a program to give iPads to each student, a program that has been plagued with problems.

In the United Kingdom, the head of the National Association of Head Teachers claimed he was dubious about using tech as a teaching aid in non-IT classes. 

Astronomers and planetary scientists have been waiting with bated breath for the first detailed close-up images of Ceres, the solar system’s largest asteroid. Now, with NASA’s Dawn spacecraft approaching closer each day, tantalizing new color imagery has revealed new details of the geological processes that formed Ceres.

Neuroscientists say the brain hormone oxytocin acts on individual brain cells to prompt specific social behaviors. 

Until now, oxytocin - the "love" hormone - has been linked to sexual attraction and things like regulating breast feeding and promoting maternal-infant bonding, but its precise effect in social behaviors is not known.

Uninsured cancer patients are asked to pay anywhere from 2 to 43 times what Medicare would pay for chemotherapy drugs, according to a new paper. Uninsured patients who did not negotiate the billed amounts could expect to pay $6,711 for an infusion of the colorectal cancer drug oxaliplatin. However, Medicare and private health plans only pay $3,090 and $3,616 for the same drug, respectively.

Although uninsured cancer patients were asked to pay on average two times more than Medicare paid for expensive chemotherapy drugs, very high payment differences were seen for drugs that were quite inexpensive on Medicare. For example, carboplatin was estimated at $26 for one infusion with Medicare, but the estimate for uninsured patients was $1,124.

I wrote this when New Horizons was approaching Pluto, and expected to find new moons and possibly a ring system. So, just as a fun question to hook this post on, I asked, could it find a moon of a moon? Or a moon with rings?
