Schools across America are switching to a four-day week, hoping to stave off the effects of budget cuts - but fuelling fears of hurting kids’ education. "State legislators and local school boards are giving administrators greater flexibility to set their academic calendars, making the four-day slate possible. But education experts say little research exists to show the impact of shortened weeks on learning. The missed hours are typically made up by lengthening remaining school days. Of the nearly 15,000-plus districts nationwide, more than 100 in at least 17 states currently use the four-day system, according to data culled from the Education Commission of the States. Dozens of other districts are contemplating making the change in the next year—a shift that is apt to create new challenges for working parents as well as thousands of school employees. The heightened interest in an abbreviated school week comes as the Obama administration prepares to plow $4.35 billion in extra federal funds into underperforming schools. The administration has been advocating for a stronger school system in a bid to make the U.S. more academically competitive on a global basis."

Harvard: Men who can do 40 pushups have a 'significantly' lower risk of heart disease

Turns out pushups are more telling than treadmill tests when it comes to cardiovascular health.

Airman 1st Class Justin Baker completes another push-up during the First Sergeants' push-up a-thon June 28, 2011, Eielson Air Force Base, Alaska. Participants were allowed 10 minutes to do as many push-ups as they could during the fundraiser. Airman Baker, a contract specialist assigned to the 354th Contracting Squadron, completed 278 push-ups. (U.S. Air Force photo/Airman 1st Class Janine Thibault)
Surprising Science
  • Men who can perform 40 pushups in one minute are 96 percent less likely to have cardiovascular disease than those who do less than 10.
  • The Harvard study focused on over 1,100 firefighters with a median age of 39.
  • The exact results might not be applicable to men of other age groups or to women, researchers warn.

  • Others note the inherent differences between the two nations, arguing that it is a good thing that it is relatively hard to pass such legislation in such a short timeframe.
  • The ban will surely shape future conversations about gun control in the U.S.
