Scientists hope JWST will help detect alien life on exoplanets

Scientists hope JWST will help detect alien life on exoplanets

Scientists searching for alien life hope that an upcoming megatelescope could reveal whether any of the recently discovered 7 Earth-size planets of the TRAPPIST-1 star system have life-supporting atmospheres.

Scheduled to be launched in 2018, the James Webb Space Telescope (JWST) will be sensitive enough to detect or identify the chemical components of the exoplanets' atmospheres as these planets will be passing in front of their host star.

Researchers store human-generated data in DNA

Researchers store human-generated data in DNA

As existing storage technologies are having a hard time keeping up with ever increasing data, scientists are trying to find a solution in biology rather than computers.

DNA molecules use biological codes to store genetic information, but a team of scientists in New York has unveiled a new technique that can allow humans to use DNA for storing human-generated data.

Nearly 4bn-year-old fossils might be earliest evidence of life on Earth

Nearly 4bn-year-old fossils might be earliest evidence of life on Earth

Straw-shaped microfossils discovered in ancient rocks in Canada could be evidence of some of the earliest life on Earth, a team of researchers led by biogeochemist Matthew Dodd reported.

Dodd, a biogeochemist at University College London, and colleagues said that the tiny, tubular structures or microfossils came from ancient microbes that existed on our planet nearly four billion years ago.

While the age of the specimens remains a matter of debate, most scientists believe that they are 3.77 billion years old, which make them the oldest ever found specimens.

Researchers identify new species of ancient marine worm

Researchers identify new species of ancient marine worm

A fresh analysis of specimens stored at the Royal Ontario Museum for more than 20 years helped researchers identify a new species of ancient marine worm, according to a new study.

The specimens were collected by Canadian scientist Derek Armstrong from a remote corner of northern Ontario in 1994. These specimens were part of 400-million-year-old rocks, in which a team of researchers from the Royal Ontario Museum, University of Bristol, and Lund University of Sweden discovered jaws from the Polychaeta.
