New Research Tests Theory that Life Originated at Deep Sea Vents

April 9, 2014

0 Comments

New research from Woods Hole Oceanographic Institution tests the theory that simple metabolic reactions near ancient seafloor hot springs enabled life as we know it to begin. One of the greatest mysteries facing humans is how life originated on Earth. Scientists have determined approximately when life began (roughly 3.8 billion years ago), but there is […]

Evidence That Organic Material Can Survive the Impact of a Meteorite

November 13, 2013

0 Comments

In a newly published study, researchers from the Natural History Museum provide the first evidence that any organic material, either inside a meteorite or already on Earth, can survive the impact of a meteorite striking the planet at high speed. New research shows that organic molecules, on which life is based, can survive the impact […]

Rudimentary Form of Life Sidesteps Normal Replication Processes

November 4, 2013

1 Comment

Researchers from the University of Nottingham have shown that in some organisms the genetic switches that control DNA replication are unnecessary and that cells will actually grow faster when the replication origins are not present. A rudimentary form of life that is found in some of the harshest environments on earth is able to sidestep […]

Scientists Recreate Patterns of Oxygen Found in the Oldest Rocks in the Solar System

October 25, 2013

1 Comment

UC San Diego cosmochemists demonstrated that a chemical reaction, governed by known physical principles, can generate silicate dust with oxygen anomalies that match those found in the oldest rocks in the solar system. Cosmochemists at the University of California, San Diego, have solved a long standing mystery in the formation of the solar system: Oxygen, […]

New Findings Challenge Assumptions about the Origins of Life

September 17, 2013

New research from biochemists at the UNC School of Medicine offers an intriguing new view on how life began, challenging current assumptions about the origins of life. Chapel Hill, North Carolina — Before there was life on Earth, there were molecules. A primordial soup. At some point a few specialized molecules began replicating. This self-replication, […]

Scientists from the University of Cambridge have discovered a natural example of a functioning gear mechanism in an insect. Previously believed to be only man-made, a natural example of a functioning gear mechanism has been discovered in a common insect – showing that evolution developed interlocking cogs long before we did. The juvenile Issus – […]

Could Life on Earth Have Originated from Somewhere Else?

September 12, 2013

7 Comments

New research presented at the European Planetary Science Congress at UCL examines whether life forms would be able to survive an impact with the surface of the Earth, opening the door to the possibility that life did not originate on Earth but came from elsewhere in the universe. It sounds like science fiction, but the […]

Archaeologists from the University College London have discovered ancient Egyptian iron beads that were made from meteoritic iron, rather than iron ore. Researchers have shown that ancient Egyptian iron beads held at the UCL Petrie Museum were hammered from pieces of meteorites, rather than iron ore. The objects, which trace their origins to outer space, […]

DNA Study Reveals Clues about Primate Evolution

July 17, 2013

1 Comment

In a new DNA study, an international team of scientists reveal clues to human and ape evolution, finding that the evolutionary history of ancestral great ape populations was far more complex than that of humans. A massive effort to catalog the genetic variation in humans, chimpanzees, gorillas and orangutans has helped researchers piece together a […]

A newly published study paints a grim outlook for the future of certain mammals and birds, suggesting that the average growing nation should expect at least 3.3 percent more threatened species in the next decade and an increase of 10.8 percent species threatened with extinction by 2050. Columbus, Ohio – The ongoing global growth in […]

Study Suggests Life on Earth is the Result of Icy Comets

June 6, 2013

1 Comment

A newly published study suggests that life on earth may have started as a result of icy comets that crashed into Earth billions of years ago. Early Earth was not very hospitable when it came to jump starting life. In fact, new research shows that life on Earth may have come from out of this […]

Middle Stone Age Innovation Linked to Rapid Climate Change

May 22, 2013

2 Comments

A newly published study presents the most convincing evidence so far that abrupt climate change was instrumental in the development human evolution. Rapid climate change during the Middle Stone Age, between 80,000 and 40,000 years ago, during the Middle Stone Age, sparked surges in cultural innovation in early modern human populations, according to new research.
