A new gamma-ray telescope will reveal new views of binary stars, black holes, and pulsars, shedding light on violent stellar explosions. The instrument, built by Columbia physicist Elena Aprile, will measure gamma rays between 300,000 to 30 million electron-volts, helping scientists understand element creation.
Researchers found a direct cause-and-effect relationship between negative emotions and an increased risk of myocardial ischemia, a precursor to heart attacks. Stress levels, both emotional and physical, were associated with a higher risk of ischemia, especially in the hour following stress.
Researchers Animesh Ray and Mitsu Ogihara built DNA logic gates using common lab techniques, marking the first step towards a DNA computer. These gates detect specific DNA fragments, splice them together, and provide output through precise measurement of new strand lengths.
A recent study reveals that the potato famine fungus has resurfaced 150 years after its devastating impact on Ireland, with virulent and fungicide-resistant strains causing widespread damage. Researchers have identified several options for managing the blight, including DNA fingerprinting and simplified enzyme assays.
