New study outlines 'water world' theory of life's origins
(Phys.org) —Life took root more than four billion years ago on our nascent Earth, a wetter and harsher place than now, bathed in sizzling ultraviolet rays. What started out as simple cells ultimately transformed into slime ...
Astronomers: 'Tilt-a-worlds' could harbor life
A fluctuating tilt in a planet's orbit does not preclude the possibility of life, according to new research by astronomers at the University of Washington, Utah's Weber State University and NASA. In fact, sometimes it helps.
Microbiologist teams with NASA research panel to find life on Mars
Are we alone in the universe? It's one of the most fundamental of questions, says Hazel Barton, an associate professor of biology at The University of Akron who joined to a panel of experts, convened by NASA, to help answer ...
Simulating how the Earth kick-started metabolism
(Phys.org) —Researchers have developed a new approach to simulating the energetic processes that may have led to the emergence of cell metabolism on Earth – a crucial biological function for all living organisms.
Bacteria manipulate salt to build shelters to hibernate
For the first time, Spanish researchers have detected an unknown interaction between microorganisms and salt. When Escherichia coli cells are introduced into a droplet of salt water and is left to dry, bacteria manipulate ...
Study shows oceans vital for possibility for alien life
Researchers at the University of East Anglia have made an important step in the race to discover whether other planets could develop and sustain life.
Under the bright lights of an aging sun
Life as we know it on Earth is linked to our star, the Sun, which provides our planet with just the right amount of heat and energy for liquid water to be stable in our lakes, rivers and oceans. However, as the Sun ages, ...
Robotic rock climbers could uncover clues to Mars' past
A robot that can scale the faces of steep cliffs might one day help explore Mars and find signs of life. The latest experiments with this "Cliffbot" showed it could help examine places otherwise difficult or impossible for ...
Study shows how early Earth kept warm enough to support life
Solving the "faint young sun paradox"—explaining how early Earth was warm and habitable for life beginning more than 3 billion years ago even though the sun was 20 percent dimmer than today—may not be as difficult as ...
Looking for life in all the wrong places
(Phys.org) —Scientists have long focused their search for extraterrestrial life on Earth-like planets – but that may be a mistake, according to a McMaster researcher.
