Delivering vaccines directly to the lungs can boost immune responses to respiratory infections or lung cancer: studyMany viruses infect their hosts through mucosal surfaces such as the lining of the respiratory tract. MIT researchers have now developed a vaccination strategy that can create an army of T cells that are ready and waiting at those surfaces, offering a quicker response to viral invaders.

Viagra May Prolong Life for Men With Coronary Artery Disease – Lower Risk of Experiencing a New Heart AttackMen with stable coronary artery disease who are on Viagra due to impotence seem to live longer and have a lower risk of experiencing a new heart attack, a study from Karolinska Institutet in Sweden published in the Journal of the American College of Cardiology reports. Impotence can be an early w

The right '5-a-day' mix is 2 fruit and 3 vegetable servings for longer lifeHigher consumption of fruits and vegetables is associated with a lower risk of death in men and women, according to data representing nearly 2 million adults. Five daily servings of fruits and vegetables, eaten as 2 servings of fruit and 3 servings of vegetables, may be the optimal amount and combination for a longer life. These findings support current U.S. dietary recommendations to eat more fruits and vegetables and the simple public health message '5-a-day.'

How hummingbirds hum: New measurement technique unravels what gives hummingbird wings their characteristic soundResearchers observed hummingbirds using 12 high-speed cameras, 6 pressure plates and 2176 microphones. The soft and complex feathered wings generate sound in a fashion similar to how the simpler wings of insect do. These new insights could help make fans and drones quieter.

Can you be scientific and spiritual?The tension between science and religion is old news to us moderns. Historical events like the Catholic Church's trial of Galileo or the Scopes Monkey Trial over teaching Darwin in schools, seem to imply that religion and science are incompatible. More recently, writers like Richard Dawkins, Daniel...

Air travel disruption after the 2010 Eyjafjallajökull eruption

Influence of volcanic tephra on photovoltaic (PV)-modules: an experimental study with application to the 2010 Eyjafjallajökull eruption, IcelandLarge volcanic eruptions may lead to significant tephra dispersion, crossing borders and affecting distant and industrial societies in various ways. While the effects of volcanic ash clouds on the aviation industry have been recognized, damaging effects on the photovoltaic energy sector are poorly investigated. Here we describe the influence of volcanic tephra deposition on photovoltaic (PV) modules that we experimentally analyzed and evaluated. A systematic set of experiments was conducted under controlled conditions using an artificial light source and measuring the electrical power generated from the PV-modules with the aim to determine the dependency of the amount of tephra covering a module and its subsequent loss in power production (measured in voltage and current) as well as the influence of the tephra grain size. We find that a mass of fine tephra has a stronger influence on the PV-modules power generation than the same mass of coarser particles. An application to the fine-grained 2010 Eyjafjallajökull eruption in Iceland and the resulting ash-cloud reveals that the power produced by PV-modules in continental Europe might have been affected significantly. Deposits were thick enough to cause complete failures of PV-modules up to a distance of about 300 km downwind. Although this distance is largely over the ocean in this particular case, our results imply that similar and larger eruptions of other volcanoes elsewhere might harm commercial or private energy production at distances of hundreds to thousands of kilometers from the volcano. Given that volcanic eruptions are frequent and the fact that the PV-industry is growing rapidly, negative impacts are expected in the future, requiring close tephra dispersion monitoring and PV-maintenance strategies.

“Friends and Strangers” Theorem – Math Professor Makes Breakthrough in Ramsey NumbersHow many people would you need at a party to guarantee that at least three individuals know each other, or that at least three do not know each other?
