Energy saving bulbs can cause cancer
Updated at: 1709 PST, Tuesday, April 26, 2011 BERLIN: Energy saving bulbs may help cut down electricity bill, but it can take a toll on health. Fears have been reignited about the safety of energy saving light bulbs after a group of scientists warned that they contain cancer-causing chemicals. Their study has found that these energy saving bulbs emit cancer-causing chemicals when switched on. |
HIV infection raises heart failure risk – study
And as the HIV virus replicates, the risk increases, added the study, published in Archives of Internal Medicine.
“Health care providers traditionally think of HIV and its therapies increasing the risk of atherosclerotic heart disease,”said lead author Adreel Butt, at the University of PittsburghSchool of Medicine in Pennsylvania.
“The surprising finding from our study was the association of HIV with heart failure in the absence of prior coronary heart disease.”
Hot baths in winter might lead to cardiac arrest: study
Taking a hot bath on a cold day may spell trouble for the heart, said a team led by Chika Nishiyama, at Kyoto Prefectural University of Medicine School of Nursing, with the rate of cardiac arrests during bathing rising ten-fold from summer to winter.
The findings could be especially significant in Japan, where bathing is a key part of life both at home and as a form of recreation, with people flocking to the country’s numerous hot springs for long, relaxing soaks.
“In Japan, most people take a deep, hot bath, since traditional Japanese homes are not well-insulated as in the west and central heating is quite uncommon,” Nishiyama and colleagues wrote in “Resuscitation.”

In memory of Moin Akhtar
When Salman Rushdie wrote “Shame,” his novel on Pakistan and its politics, he chose to use a mentally-challenged child as a symbol for the country. In his mind, Pakistan was a “dream less imagined” and the shame felt by the characters in the book towards the child was akin to the shame felt by the country’s people towards their own identity.
For all the effigies burnt, fatwas issued and death threats launched, Rushdie had a point. It is not easy trying to make sense of this country, which forever seems to be ripping at its seams, forever dangling at the precipice. Unfortunately, the common response by the high and mighty amongst us is to try and show the rest of the world how we are not who they think we are – the tragedy being that all that effort would be better spent at introspection.

Black Holes
Black Holes
Don't let the name fool you: a black hole is anything but empty space. Rather, it is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City. The result is a gravitational field so strong that nothing, not even light, can escape. In recent years, NASA instruments have painted a new picture of these strange objects that are, to many, the most fascinating objects in space.
Outer Solar System
Outer Solar System
NASA’s Planetary Science missions to the outer planets help reveal secrets about the solar system by observing those outer distant worlds up close. Jupiter’s moon Europa and Saturn’s moon Enceladus are now thought to hide liquid water beneath their frozen surfaces and are high priority targets for NASA. Unlocking their secrets and those of the outer planets will help scientists understand more about planet Earth and the formation and evolution of the solar system.
Inner Solar System
Inner Solar System
Planetary Science missions, past, current, in planning or in development, extend mankind’s presence to the solar system’s inner rocky worlds, helping to unlock the secrets of the solar systems’ composition, history and evolution, and how life established itself on Earth.

Mercury is the least explored terrestrial or “rocky” planet in our solar system. Previously NASA’s only encounters with the innermost planet were the three flybys performed in 1974 and 1975 by the Mariner 10 mission that mapped 45 percent of the planet’s surface. In January 2008, the MESSENGER spacecraft flew by Mercury for its first of three fly-bys. As it begins to reveal the planet’s composition and history, it will in turn, help scientists understand more about our home planet and its place in the inner solar system.
Venus has often been described as Earth’s sister planet since the two are very similar in size and bulk composition, although they evolved to very different ends. Venus is not currently targeted by any NASA missions although future mission concepts include the Venus In Situ Explorer (VISE) and Venus Mobile Explorer (VME) that would investigate the surface of Venus and help understand the climate change processes that led to the extreme conditions of Venus today. A Venus Surface Sample Return (VSSR) mission is also being considered. These missions remain long-range goals for Venus exploration.
Earth’s Moon has a special place among the objects of the solar system, as it is the only body other than Earth where humans have journeyed to and where humans will return relatively soon. NASA is sending robotic missions to the moon to prepare for mans’ prolonged habitation on the lunar surface which ultimately will help man reach for Mars and attain the goals set forth in the Vision for Space Exploration (VSE). Studying the Moon and its history provides insight on the formation history of the Earth-Moon system and events that shaped the inner solar system.
Mars is a highly attractive object of study: not only does it provide an excellent laboratory for studying planetary evolution in the context of the Earth and Venus, but it is the most compelling target in the solar system to search for life’s existence beyond Earth. Additionally, Mars is an eventual goal of the Vision for Space Exploration’s human spaceflight program. Finally, Mars is relatively easily accessed with launch opportunities occurring approximately every 2 years. For these reasons, the Mars Exploration Program is a fully integrated program, designed to maximize the scientific return, technology infusion, and public engagement of the robotic exploration of the Red Planet. Each strategic mission of the program has both technological and scientific linkages to previous missions and orbiters, and landers support each other’s operations.
