We may idealize the last century but natural forces have always caused climate on Earth to fluctuate - sometimes quite a bit. But science is about controlling nature and not letting random behavior control our destinies and since we know that some periods were good and some awful, we'd like to avoid the awful.

We can't control everything - the earth is still going to orbit the sun and such orbital forcing of climate change happens over thousands of years and brings ice ages and warming periods. 

Many mammals, and some birds, escape the winter by hibernating for three to nine months. This period of dormancy permits species which would otherwise perish from the cold and scarce food to survive to see another spring.

The Middle East, with temperate winters, was until recently considered an unlikely host for hibernating mammals.

Though every month we read about some new advance in artificial intelligence, how much progress is really being made?  Neuromorphic computing has created software and electronic hardware that mimic brain functions and signal protocols but, like economic models that successfully predict the past, they have only slightly improved the efficiency and adaptability of conventional technology and are not really making bold advances. 

Male partners of infertile obese females may increase the odds of conceiving a child by improving their own weight and dietary habits, preliminary results from a pilot study from Canada suggest. The results will be presented Thursday, March 5, at ENDO 2015, the annual meeting of the Endocrine Society in San Diego.

In this country, poor diet, obesity and high rates of smoking have compounded to give nearly 75 percent of adults poor cardiovascular health.

It's not the United States, it is China, yet an alarming number of health plans promoted by American nutrition pundits advocate Asian lifestyles. 

The 2010 China Noncommunicable Disease Surveillance Group collected cardiovascular health data from a nationally representative sample of more than 96,000 men and women in the general Chinese population.

A history of psychedelic drug use is associated fewer suicidal thoughts, planning and attempts, according to survey results analyzed by Johns Hopkins and the University of Alabama at Birmingham.

In a national survey of over 190,000 U.S. adults, lifetime use of certain psychedelic drugs was associated with a 19 percent reduced likelihood of psychological distress within the past month, a 14 percent reduced likelihood of suicidal thinking within the past year, a 29 percent reduced likelihood of suicide planning within the past year and a 36 percent reduced likelihood of attempting suicide within the past year.
