A new study, believed to the largest randomized trial to directly compare changes in body composition induced by comparable amounts of time, has found that aerobic training is better than resistance training for weight- and fat loss. 

They measured time spent doing aerobic and resistant training, or both in combination, among previously inactive overweight or obese non-diabetic adults.  

Methodology

BPA - Bisphenol A - has been besieged by so much negative public relations that it is almost indefensible. Like smoking, people are going to blame it for everything they can. 
 
But research is sometimes about inconvenient truths and so a three-year study using more than 2,800 mice that was not able to replicate a series of previous studies finding harm has to be mentioned.  The authors are quick to note they are not declaring BPA safe, rather just that they could not reproduce the developmental effects of BPA in babies in the womb - which used to be the definition of safe. The estrogenic compound found in plants, genistein, was also studied and results of other studies could not be reproduced.

Though you can't put science data to a vote, the policies based on science are for the public to decide.

Until a global policy is in place, scientists and organizations can easily circumvent international laws regarding geo-engineering by getting domestic approval, as we saw with LOHAFEX and environmental activist Russ George dumping iron in the ocean to create algal blooms, in defiance of treaties prohibiting it.

A radiotracer has shown that researchers who used electricity on certain regions in the brain of a patient with chronic, severe facial pain led to release of an opiate-like substance that's considered one of the body's most powerful painkillers.  

In their current study, researcher intravenously administered a radiotracer that reached important brain areas in a patient with trigeminal neuropathic pain (TNP), a type of chronic, severe facial pain. They applied the electrodes and electrically stimulated the skull right above the motor cortex of the patient for 20 minutes during a PET scan (positron emission tomography). The stimulation is called transcranial direct current stimulation (tDCS).

Reconstructions of atmospheric CO2 concentrations and sea level over the past 40 million years show that greenhouse gas concentrations similar to the present (nearly 400 parts per million) were associated with sea levels at least nine meters above current levels. 

They determined the 'natural equilibrium' sea level for CO2 concentrations ranging between ice-age values of 180 parts per million and ice-free values of more than 1,000 parts per million.  Of course, it takes centuries for equilibrium to be reached so they don't try to predict any sea level value for the coming century but it can help illustrate what sea level might be expected if climate were stabilized at a certain CO2 level for several centuries. 

A team of archaeologists has made discoveries of extensive water management and agricultural production in and around the ancient desert city of Petra, located in present-day Jordan. 

Successful terrace farming of wheat, grapes and possibly olives resulted in a vast, green, agricultural "suburb" to Petra in an otherwise inhospitable, arid landscape. This terrace farming remained extensive through the third century and surface finds plus comparative data shows this type of farming continued in some extent until around the end of the first millennium, between 800 and 1000 A.D.
