An anonymous reader writes with news of research into the scientific literacy of college biology students. Earlier studies found that students tended to "rely on mainly informal reasoning derived from their personal experiences," so the researchers derived a new instructional framework that explicitly taught principle-based reasoning. While the number of students who used this method did increase, more than half continued to use informal reasoning, which the researchers say points to a flaw in the way biology is taught (PDF). "Most college-level instruction presents students with complicated narratives about the details of key processes (e.g., cellular respiration), but does not explicitly reinforce the use of key principles to connect those processes. Therefore, students are understandably occupied with memorizing details of processes without focusing on the principles that govern and connect the processes. ... As a result, students may leave an introductory biology course with the ability to recite the reactions in the Calvin cycle but still believing that plants obtain most of their mass from the soil rather than from the atmosphere, that plants photosynthesize but do not respire, or that the mass of a decomposing organism will primarily return to the soil."

theodp writes "Writing for Forbes, CS-grad-turned-big-time-VC Ben Horowitz gives three examples of how the smartest people in a company can also be the worst employees: 1. The Heretic, who convincingly builds a case that the company is hopeless and run by a bunch of morons; 2. The Flake, who is brilliant but totally unreliable; 3. The Jerk, who is so belligerent in his communication style that people just stop talking when he is in the room. So, can an employee who fits one of these poisonous descriptions, but nonetheless can make a massive positive contribution to a company, ever be tolerated? Quoting John Madden's take on Terrell Owens, Horowitz gives a cautious yes: 'If you hold the bus for everyone on the team, then you'll be so late that you'll miss the game, so you can't do that. The bus must leave on time. However, sometimes you'll have a player that's so good that you hold the bus for him, but only him.' Ever work with a person who's so good that he/she gets his/her own set of rules? Ever been that person yourself?"

A UK bookmaker has lowered the odds on proving that god exists to just 4-1 to coincide with the switching on of the Large Hadron Collider. The chance that physicists might discover the elusive sub-atomic object called the "God particle" has forced the odds lower. Initially the odds that proof would be found of God's existence were 20-1, and they lengthened to 33-1 when the multi-billion pound atom smasher was shut down temporarily because of a magnetic failure. A spokesman for Paddy Power said, "The atheists' planned advertising campaign seems to have renewed the debate in pubs and around office water-coolers as to whether there is a God and we've seen some of that being transferred into bets. However we advise anyone still not sure of God's existence to maybe hedge their bets for now, just in case." He added that confirmation of God's existence would have to be verified by scientists and given by an independent authority before any payouts were made. Everyone getting a payout is encouraged to tithe at least ten percent.

An anonymous reader writes "A guy at Lumenlab has created a way to carve his face on a pumpkin using his DIY CNC gantry robot. I think this demonstration says a lot about the future ubiquity of the technology. I'm really looking forward to the day that I have one of these machines in my garage."

Hugh Pickens writes "As many as three American Airlines passenger jets will be outfitted this spring with laser technology intended to protect planes from missile attacks. The tests, which could involve more than 1,000 flights, will determine how the technology holds up under the rigors of flight. The technology is intended to stop attacks by detecting heat from missiles, then responding in a fraction of a second by firing laser beams to jam the missiles' guidance systems. A Rand study in 2005 estimated it would cost about $11 billion to protect every US airliner from shoulder-fired missiles. Over 20 years, the cost to develop, procure and operate anti-missile systems could hit $40 billion."

tanman writes "A student at the Houston-area Clements High School was arrested, sent to an "Alternative Education Center" and banned from graduation after school officials found he created a video game map of his school. School district police arrested the teen and searched his home where they confiscated a hammer as a 'potential weapon'. ' "They decided he was a terroristic threat," said one source close to the district's investigation.' With an upcoming May 12 school board election, this issue has quickly become political, with school board members involved in the appeal accusing each other of pandering to the Chinese community in an attempt to gain votes."
