Early in his career, Paul Olsen sat in front of a television, expecting to see his own image. He had hosted a television crew on a research expedition to Manicouagan Crater in Canada, where he and his team were investigating the Triassic–Jurassic boundary in the geological record. Olsen, a palaeontologist at Lamont–Doherty Earth Observatory of [...]
In the scientists’ lounge aboard the BIO Hespérides one evening last March, Jordi Dachs points at the schedule for the next day’s oceanographic observations. The Spanish research vessel is chugging across the Indian Ocean at a speed of about ten knots. “The storm has put us seven hours behind,” warns Dachs, an environmental chemist at [...]
It’s early June in the Austrian Alps. Tourists in shorts sweat their way up a trail from the cable car above Lake Hallstatt. But the summer heat doesn’t stop a group of scientists from pulling on brightly colored jumpsuits over their hiking clothes at the entrance to Mammuthohle, one of the many limestone caves that [...]
José Ordovas sips a mint tea in a languid café in Madrid, Spain. His eyes scan two mobile phones as he confirms his next appointments. In conversation, he switches effortlessly between Spanish and English to find the right expressions.
Ordovas embodies the hustle and bustle of the ‘big science’ approach that has changed nutrition research in the past decade. This field, once confined to small groups of researchers studying the effects of single nutrients — such as particular vitamins or proteins — on a few dozen volunteers, is now adopting the heavy-lifting tools developed for genetics and pharmaceutical research. It also has a catchy name: nutrigenomics.
EISRIESENWELT, AUSTRIA—Tracing his glove along a chalky layer in a house-size block of ice that lines this cave in the Austrian Alps, Michael Behm can feel all that is left of an ancient warm spell. The ice, likely formed over the decades or centuries as calcium-enriched rainwater trickled deep into the cave and froze, must [...]
The propeller-driven six-seater churns straight toward the brown plume over Eyjafjallajökull, unlike other aircraft taking off from Reykjavík airport. Inside, accompanied by a seasoned pilot, sits Björn Oddsson, a graduate student at the University of Iceland, entrusted with an infrared sensor derived from military bombing systems. But the only bombs Oddsson talks about are the [...]
Argentina has blazed a trail as one of the leading genetically modified (GM) crop producers. Can other developing countries import the seeds of its success?
REYKJAVIK—As a brown cloud of ash drifts down from the slopes of Eyjafjallajökull toward their truck, Hanna Kaasalainen warns a colleague that their gas masks won’t be much good against carbon dioxide. The masks filter out poisonous gases released by magma such as sulfur dioxide, but carbon dioxide can simply displace oxygen in the air, [...]
Grabbing one of the three laptops in her office at Microsoft Research in Cambridge, UK, Jasmin Fisher flips open the lid and starts to describe how she and her collaborators used an approach from computer science to make a discovery in molecular biology. Fisher glances across her desk to where her collaborator, Nir Piterman of [...]
Like most stem cell biologists, Helen Mardon obtained her first cell lines from someone she knew. Later, when she needed more material, she chose to pay for a line from a commercial dealer. Eventually, the Oxford Stem Cell Institute co-director derived her own in-house human embryonic stem cell core from embryos donated by in vitro [...]
