DNA

The difference between biological age and chronological age, as shown on our birth certificates, can reveal health problems associated with premature aging, and now scientists have devised a tool to study it in children for the first time.

A new Japanese study simulated interstellar clouds of dust and gas, and managed to produce some of the building blocks of DNA.

Researchers have managed to reconstruct a Denisovan face for the first time, using DNA methylation mapping techniques.

Led by scientists from the Children’s Hospital of Philadelphia, a new study is homing in on a single gene suggested to be a master regulator in schizophrenia.

After analyzing DNA found in Loch Ness, a scientist believes the monster might be a type of giant eel.

New MIT and Harvard research shows how versatile CRISPR is, putting the genetic scissors to work in diagnostic tools and timed drug delivery systems.

A new blood test has been developed that promises to be able to effectively track the progression of breast cancer at its earliest stages. It is suggested the blood test could track the efficacy of drug therapies better than current imaging techniques and prevent unnecessary surgical procedures.

Under the right conditions, DNA can last for thousands of years. RNA, on the other hand, degrades much more quickly and was thought impossible to recover in older samples. But now researchers have isolated and sequenced the RNA of a 14,000-year-old wolf found frozen in the Siberian permafrost.

The human genome can tell us where we’ve come from, and it’s hiding more than a few surprises. Now researchers from the University of Adelaide have found evidence of two unknown, archaic human species in modern DNA.

A Stanford University team is developing plants that can better absorb iron from the soil. By making it easier to ingest the trace mineral, it may be possible to open up the roughly one-third of the world's arable land that is unsuitable for growing staples like maize and soybeans.

Mitochondrial DNA in plants is so complex that scientists haven’t yet been able to edit the genes in there. Now a team of Japanese researchers has managed to do just that, which could help improve the genetic diversity of crops.

Researchers at the Technical University of Munich (TUM) have demonstrated a prototype of a drug that can release three active ingredients, at different times in sequence. The key to this unusual and useful ointment is artificial DNA, which breaks down at precise intervals.
