  • Suzaku X-ray observatory spies treasure trove of intergalactic metal
    Most of the universe is made up of hydrogen and helium. These cosmic lightweights fill the first two spots on the famous periodic table of the elements. Less abundant but more familiar to us are the heavier elements. Recently astronomers used the Suzaku orbiting X-ray observatory, operated jointly by NASA and the Japanese space agency, to discover the larges […]
  • Adult stem cells may help repair hearts damaged by heart attack, study suggests
    Adult stem cells may help repair heart tissue damaged by heart attack according to the findings of a new study. Results from the Phase I study show stem cells from donor bone marrow appear to help heart attack patients recover better by growing new blood vessels to bring more oxygen to the heart.
  • Waterpipe tobacco smokers inhale same toxicants as cigarette smokers
    Smoking tobacco through a waterpipe exposes the user to the same toxicants -- carbon monoxide and nicotine -- as puffing on a cigarette, which could lead to nicotine addiction and heart disease, according to a new study.
  • Brain tumor cells made more responsive to radiation
    Researchers have figured out how stem cells in the malignant brain cancer glioma may be better able to resist radiation therapy. And using a drug to block a particular signaling pathway in these cancer stem cells, they were able to kill many more glioma cells with radiation in a laboratory experiment.
  • Hidden protein structures are essential for catalysis
    A new study raises the curtain on the hidden lives of proteins at the atomic level. The study reports that for the first time, researchers used x-ray crystallography and nuclear magnetic resonance (NMR) techniques to directly visualize protein structures essential for catalysis at the rare high-energy state. The study also showed how the motions of these rar […]
  • Young adults who exercise get higher IQ Scores
    Young adults who are fit have a higher IQ and are more likely to go on to university, reveals a major new study.
  • Synthetic magnetic fields 'trick' neutral atoms into acting as if electrically charged
    Achieving an important new capability in ultracold atomic gases, researchers have created "synthetic" magnetic fields for ultracold gas atoms, in effect "tricking" neutral atoms into acting as if they are electrically charged particles subjected to a real magnetic field.
  • Ecstasy use may lead to sleep apnea: Illegal 'club drug' poisons neurons involved in control of breathing during sleep
    Repeated use of the drug popularly known as "ecstasy" significantly raises the risk of developing sleep apnea in otherwise healthy young adults with no other known risk factors for the sleep disturbance, a new study suggests. The finding is the latest highlighting the potential dangers of the amphetamine-style chemical, currently used illegally by […]
  • Variable temperatures leave insects with a frosty reception
    For the first time, scientists have shown that insects exposed to repeated periods of cold will trade reproduction for immediate survival.
  • Latest epidemic? High cholesterol, obesity in fruit flies
    How do fruit flies get high cholesterol and become obese? The same way as people do -- by eating a diet that's too rich in fats.
