PROBLEM: After enduring one too many maddeningly slow boarding experiences  Jason Steffen a professor of physics and astronomy at the University of Nevada Las Vegas  began digging into the unexpectedly complicated mechanics of efficiently ushering passengers onto planes.
In 2008   Steffen  created a computer simulation to evaluate existing boarding methods and ultimately design what  he  claims is the most efficient option for getting restless passengers into their seats. The results were published several years ago in the Journal of Air Transport Management (summarized here).
In  his  research   Steffen  identified the two most common factors responsible for slowing the boarding process to a painful crawl:
In fact  the most routine boarding process â from back to front â is actually the slowest of them all   Steffen âs argues  Itâs even less efficient than boarding a plane in a completely random order.
 Steffen  claims that  his  proposed method  which minimizes the former issue and eliminates the latter  could significantly reduce boarding times  thus cutting down on overall door-to-door flight lengths  and ultimately saving airlines hundreds of millions of dollars a year.

SOLUTION: Jason Steffen

PROBLEM: "It is impossible not to conclude that McHugh knew full well he was purposefully and illegally exposing his tenants to catastrophic injury and death " the suit said. Noe Duran  the roommate who escaped the fire  is also a party to the suit.
 McHugh could not be reached for comment. His attorney  Greg Stannard  said he had not had time to review the case and could not comment.
 McHugh is under a court order to sell all his rental properties in Los Angeles by the fall of 2010 as part of a plea agreement to avoid jail time for fire and habitability violations.
 City officials have been trying to regulate McHugh for decades. In the 1980s  then-City Attorney Ira Reiner accused McHugh  now 84  of dealing in "blood money" and threatened to put him in jail.
 But the landlord continued to amass buildings and a record of violating health and safety codes. Last summer  his lawyer told city officials that he owned more than 140 properties  housing about 8 000 people  many of them impoverished immigrants in the city's core.
 Tenants and their advocates say the conditions in his buildings caused health risks such as lead poisoning  asthma and ear infections caused by allergy to cockroaches.

SOLUTION: McHugh

PROBLEM: The concentration  or number of insulin units in the liquid solution  was labeled as 100 units per milliliter. But they averaged less than half of that  and none met the 95-unit minimum standard  said lead researcher Alan Carter  a pharmacist and adjunct instructor at the University of Missouri-Kansas City School of Pharmacy.
 Carter  thinks the insulin may have gotten too warm somewhere between the factory and the pharmacy  causing some of the molecules to break apart.
 Carter  wondered whether  his  results might help explain why insulin users sometimes find a dose doesn't work as well as normal. Doctors usually attribute that to patient error: not injecting enough insulin before a meal  not following dietary guidelines  or skipping exercise.
 Carter   who had a limited budget for  his  study  acknowledges that it was too small and that  his  results may be flawed. He notified Novo Nordisk and Eli Lilly of his results in hopes someone would do a bigger follow-up study.
