Nanopores promise cost savings in gene sequencing

(Phys.org)—In the last five years, next-​​generation gene sequencing has brought down the cost of unlocking a single genome from $10 mil­lion to $10,000. While the sav­ings is unprece­dented, more can still be done ...

In cod we trust: DNA test combats fisheries fraud

Scientists on Tuesday said they had devised a DNA test to pinpoint the geographical origins of commercial seafish, in a breakthrough against illegal trawling that threatens fish stocks worldwide.

lobSTR algorithm rolls DNA fingerprinting into 21st century

As any crime show buff can tell you, DNA evidence identifies a victim's remains, fingers the guilty, and sets the innocent free. But in reality, the processing of forensic DNA evidence takes much longer than a 60-minute primetime ...

Tiny reader makes fast, cheap DNA sequencing feasible

Researchers have devised a nanoscale sensor to electronically read the sequence of a single DNA molecule, a technique that is fast and inexpensive and could make DNA sequencing widely available.

Two-step technique makes graphene suitable for organic chemistry

The future brightened for organic chemistry when researchers at Rice University found a highly controllable way to attach organic molecules to pristine graphene, making the miracle material suitable for a range of new applications.

Biologists uncover a novel cellular proofreading mechanism

(PhysOrg.com) -- To make proteins, cells assemble long chains of amino acids, based on genetic instructions from DNA. That construction takes place in a tiny cellular structure called a ribosome, to which amino acids are ...

RNA reactor could have served as a precursor of life

(PhysOrg.com) -- Nobody knows quite how life originated on Earth, but most scientists agree that living cells did not abruptly appear from nonliving cells in a single step. Instead, there were probably a series of pre-cellular ...
