Researchers have discovered organic molecules trapped in incredibly ancient rock formations in Australia, revealing what they say is the first detailed evidence of early chemical ingredients that could have underpinned Earth's primeval microbial life-forms.
In a major register-based study, scientists at University of Gothenburg, Sweden, have now demonstrated a connection between inferior physical fitness in young adults and elevated risk of the autoimmune disease psoriasis. For the male recruits to compulsory military training who were rated as the least fit, the risk of developing psoriasis later was 35 percent higher than for the fittest.
An international research team that included three scientists from the University of Rhode Island’s Graduate School of Oceanography has discovered single-celled microorganisms in a location where they didn’t expect to find them.
How life originated on Earth continues to fascinate scientists, but it's not easy peering back billions of years into the past. Now, evidence is growing for a relatively new hypothesis of how life began: With a very precise mix of RNA and DNA.
In a study of women aged 80 years and older, living in locations with higher exposures to air pollution was associated with increased depressive symptoms. The findings were published in the Journal of the American Geriatrics Society.
A hiker who was rescued after being lost overnight in a whiteout in Mount Rainier national park, Washington, the US, died in the emergency room but was brought back to life after his heart stopped for 45 minutes.
Earth is not necessarily the best planet in the Universe. Researchers have identified two dozen planets outside our Solar System that may have conditions more suitable for life than our own. Some of these orbit stars that may be better than even our Sun.
