Heavy hydrogen tracks glucose metabolism in vivo

Researchers at Yale University have reported a new imaging modality, known as deuterium metabolic imaging (DMI), in which sugars and other nutrients are labelled with a heavy hydrogen (2H) atom and subsequently administered to track and monitor their uptake and metabolism.

Mapping glucose metabolism is important for monitoring the development and treatment of cancer, as tumours metabolize glucose both at an elevated rate and through a different set of chemical reactions compared with healthy tissue — a phenomenon known as the Warburg effect. Read more.

Cremated remains reveal hints of who is buried at Stonehenge

Chemical analyses of skull pieces suggest some of the dead came from Wales

A new analysis of cremated human remains interred at the iconic site between around 5,000 and 4,400 years ago provides the first glimpse of who was buried there. Some were outsiders who probably spent the last decade or so of their lives in what’s now West Wales, more than 200 kilometers west of Stonehenge, researchers report. Read more.

New Date For Greek Eruption That May Have Inspired Atlantis Myth

A long-standing controversy over the date of a volcanic blast that possibly inspired the myth of Atlantis may have been resolved with the aid of ancient tree rings, a new study finds.

One of the largest volcanic eruptions in the past 4,000 years burst from the volcano Thera on what is now the Greek island of Santorini. The catastrophic eruptions spewed forth about 40 to 60 cubic kilometers of lava, devastating the ancient seafaring Minoan civilization, potentially inspiring the legend of the lost city of Atlantis.

Ancient natural fission reactor offers clues on how to store modern nuclear waste

A team of researchers from the US Naval Research Laboratory and Washington University has learned more about possible ways to store modern nuclear waste by studying an ancient natural fission reactor. In their paper published in Proceedings of the National Academy of Sciences, the group describes their study of cores taken from the natural Oklo nuclear reactor and what they found. Read more.
