The propagation of light -observed and governed since ancient times by simple lens construction- has long been described through classical geometrical optics. However, in particle accelerators we do not transport photons but beams of electrically charged particles subjected to repulsive forces that tend to unpack the particle beams. Optics of particle accelerators require electromagnetic lenses […]
NASA plans to send crewed missions to Mars over the next decade – but the 140 million-mile (225 million-kilometer) journey to the red planet could take several months to years round trip. This relatively long transit time is a result of the use of traditional chemical rocket fuel. An alternative technology to the chemically propelled […]
Many large mammals have lost genetic diversity, often thanks to the actions of people shrinking their populations. The implications can be severe because without genetic diversity, a population does not have a “genetic database” to fall back on to adapt to environmental change. The Iberian lynx (Lynx pardinus) is no stranger to this reduction in […]
Author: Ramón Muñoz-Chápuli has been Professor of Animal Biology in the University of Málaga until his retirement. He has investigated for forty years in the fields of developmental biology and animal evolution. Lungfish (Dipnoi) are fascinating animals. Despite having gills, they can breathe atmospheric air thanks to a pair of lungs. Their geographic distribution aligns […]
What would happen if humans dried out the Mediterranean sea, turning it into a giant salt lake? Would its wildlife survive, and if so, how long would it take to recover? These may seem like wildly theoretical questions, but not for Herman Sörgel, a Bavarian architect who dedicated much of his life to this exact […]

Author: Tom Shand, Honorary Senior Lecturer, Department of Civil and Environmental Engineering, University of Auckland, Waipapa Taumata Rau As the Olympics get going in earnest this week, not everyone’s attention is focused on host city Paris. Surf fans are heading to Tahiti, half a world away in French Polynesia. Why? Well, apart from the French […]
Acute myeloid leukemia (AML) is a major hematopoietic malignancy characterized by the uncontrolled expansion of the immature myeloid cells . The 5-year survival rates of young patients are 40–50% and less than 15% for patients aged over 60 . For this reason, a great effort has been made to decipher the molecular events underlying AML […]

Author: José R. Pineda got his Ph.D. from University of Barcelona in 2006. Since 2007 he has worked for Institut Curie and The French Alternative Energies and Atomic Energy Commission. Currently he is a researcher of the UPV/EHU. He investigates the role of stem cells in physiologic and pathologic conditions. There is strong evidence that […]
