Given a choice, it's better to be miserable in a heated jacuzzi than be homeless on the streets of New York City during a blizzard.

But that 'money can't buy happiness' saying arose because some people just can't be happy - and money won't help. Psychology is subjective and relative so we're only left with averaging surveys but, generally, people who spend more on life experiences are happier than people who just buy stuff. Plenty of people are happy when they buy a new phone or a TV but it quickly becomes commonplace. If you are a football fan, and finally buy that trip to the Super Bowl, you are pretty happy.

It's not only the biology of lakes that varies with the climate and other environmental factors, it's also their chemistry. More knowledge about this is needed to understand the ecology of lakes and their role in the carbon cycle and the climate. Today an international research group led by Uppsala University is publishing a comprehensive study of the composition of organic compounds in the prestigious journal Nature Communications.

New York, NY, May 1, 2014 – We may soon be able to make easy and early diagnoses of prostate cancer by smell. Investigators in Finland have established that a novel noninvasive technique can detect prostate cancer using an electronic nose. In a proof of principle study, the eNose successfully discriminated between prostate cancer and benign prostatic hyperplasia (BPH) by "sniffing" urine headspace (the space directly above the urine sample). Results using the eNose are comparable to testing prostate specific antigen (PSA), reports the Journal of Urology®.

The combined heat from climate change and urbanization is likely to reduce the number of eastern swallowtails and other native butterflies in Ohio and promote the spread of invasive relatives, a new study led by a Case Western Reserve University researcher shows.

Among 20 species monitored by the Ohio Lepidopterists society, eight showed significant delays in important early lifecycle events when the two factors were combined—a surprising response that may render the eight unfit for parts of the state where they now thrive.

RICHLAND, Wash. – Killer whales and other marine mammals likely hear sonar signals more than we've known.

That's because commercially available sonar systems, which are designed to create signals beyond the range of hearing of such animals, also emit signals known to be within their hearing range, scientists have discovered.

The sound is likely very soft and audible only when the animals are within a few hundred meters of the source, say the authors of a new study. The signals would not cause any actual tissue damage, but it's possible that they affect the behavior of some marine mammals, which rely heavily on sound to communicate, navigate, and find food.

Physically active kids who spend a lot of time outdoors are not only healthier, they have a stronger sense of self-fulfillment and purpose than those who don't - and more spirituality too.

In the Journal of the Study of Religion, Nature and Culture paper, children who played outside five to 10 hours per week said they felt a spiritual connection with the earth and felt their role is to protect it.
