The secret to longevity in tubeworms
With an incredible lifespan of up to 250 years the deep sea tube worm, Lamellibrachia luymesi is among the longest-lived of all animals, but how it obtains sufficient nutrient ?in the form of sulfide - to keep going for this long has been a mystery. In a paper just published in the premier open-access online journal PLoS Biology, Erik Cordes and colleagues now provide a solution: by releasing its...Amino acids in nectar enhance butterfly fecundity: A long awaited link
The fascinating interactions between flowers and their pollinators have resulted in a spectacular diversity of plants. In order to entice pollinators such as bees, flies or butterflies to visit and successfully pollinate their flowers, plants have evolved intriguing mechanisms and attractants, of which nectar is best known. Thirty years ago, researchers discovered that nectars of flowers...Sexual cooperation: Mating increases longevity in ant queens
The phenomenon of sexual conflict is a powerful driving force in the evolution of reproductive biology for many animal species. Males often try to manipulate their female mates during copulation--for example, by traumatic inseminations (as in the case of bed bugs) or by the transfer of toxic seminal fluids (as in the case of the fruitfly Drosophila). These manipulations are beneficial to males be...At long last, scientists figure out how plants grow
It has been one of the great mysteries in plant science. In this week's Nature, Indiana University Bloomington biologists Mark Estelle, Nihal Dharmasiri and Sunethra Dharmasi...Finnpipette Focus Single Channel Long Tip Cone 30-300l from Thermo Scientific

Many more patients with chronic pancreatitis can safely turn to a minimally invasive operation for long-term pain relief, according to a new study by Johns Hopkins University physicians. Endoscopic therapy is an effective alternative to more invasive surgery or drugs, says Anthony N. Kalloo, MD, director of GI endoscopy at Hopkins and lead author of the study that appeared in the July...Long-Term Survival can be Predicted by a Simple Lung Test
Researchers have found a simple pulmonary test can predict overall long-term survival rates in both men and women. Their findings are presented in the September issue of Chest. Researchers studied survival rates based on a lung function test, called forced expiratory volume in one second (FEV1).They performed the lung function test on a group of more than 550 men and more than 640 wom...“Don’t fear long haul flights!” Vascular surgeon tells travelrs
Dr. John Scurr, a vascular surgeon at London's Middlesex Hospital, advices passengers, who fly long haul flights, that there is nothing to fear. The death of a woman on board an airliner, while she was flying a long distance flight, has sparked off this sudden debate that long flights can be fatal to many people. Dr. Scurr says this fear is unfounded and that people are just ove...Blood clots likely in long travel
A new study has found that the risk of developing a blood clot in the lung - called a pulmonary embolism - increased with the duration of air travel.Like deep vein thrombosis (DVT), pulmonary embolisms are blood clots that are believed to be associated with long-distance travel. Frederic Lapostolle and colleagues, from Avicenne Hospital in Bobigny near Paris, studied all cases of pulm...Weiss Retinal Pick 90 Degree Long
