Laser light can reveal condition of ship paint
With infrared laser light, researchers from DTU Fotonik can produce detailed 3D images of ship paint, so that the paints can become more durable and environmentally friendly.
Christian Rosenberg Petersen had a bright idea a couple of years ago. He decided to find out whether infrared light could be used to examine ship paint. Not just in the lab, but onsite at the ships.
The idea did not come completely out of the blue, but from an article published in Ingeniøren. The article was about a new type of ship paint developed and tested in a collaboration between the company Hempel and researchers from DTU. It described how the researchers continually observed a paint sample under the electron microscope to follow how its durability and corrosion protection evolved over time.
Rare and exotic upside-down lightning might be quite mundane after all
In the time it has taken me to write this, lightning has struck the earth over 500 times. It is one of the most spectacular, mesmerizing, and awe-inspiring natural phenomena. For all of its beauty and power, it still holds many mysteries.
As recently as the 1990s, we had only anecdotal evidence of the majority of lightning’s many incarnations. At that time, thanks to videotape evidence from NASA’s Space Shuttle missions, actual observations of sprites, jets, and later ELVES (Emissions of Light and Very Low-Frequency Perturbations From Electromagnetic Pulse Sources) would all be confirmed and studied.

46 mio. kr. for seven young researchers
Seven young DTU researchers receive Villum Young Investigator grants for a total of DKK 46 million.
Villum Fondens Villum Young Investigator programme allows talented Danish and international researchers to pursue their ideas and establish their own research groups at Danish universities.
“The only thing we know today about the new knowledge that will shape our lives in 20 years’ time is that it is largely being created in the minds of talented young researchers. It is therefore important to give young researchers a solid starting point for establishing their own research profiles,” says Thomas Bjørnholm, Executive Chief Scientific Officer of VILLUM FONDEN in connection with the awarding of grants.

Of all the weather phenomena our magnificent planet throws at us, lightning is one of the most spectacular - and the most mysterious. Even though storms are a regular occurrence, we re still at pains to understand and describe their crackling electrical discharges generated in the sky.
One kind of lightning is so strange and rare, in fact, that we didn t even have concrete evidence it existed until 1990, when researchers identified its signature rocket-like motion in video shot from NASA s Space Shuttle the previous year.
Later dubbed blue jets , the streaks are now recognised as brilliant flashes of light that last just a few hundred milliseconds, as lightning streaks upwards from the clouds and into the stratosphere.

Personalized vaccine produces long-lasting anti-tumor response in patients with melanoma, study shows
Four years after patients with melanoma were treated with a personalized cancer vaccine, the immune response kindled by the vaccine remains robust and effective in keeping cancer cells under control, researchers at Dana-Farber Cancer Institute, Brigham and Women’s Hospital, and the Broad Institute of MIT and Harvard report in a new study.
The findings, published online today by the journal Nature Medicine, demonstrate the staying power of the immune response generated by the vaccine, known as NeoVax, which works by targeting specific proteins on each patient’s tumor cells. The researchers found that, nearly four years after vaccination, the patients’ immune system cells were active not only against tumor cells with those distinctive proteins, but also spread to other proteins found in those patients’ tumor cells.
