DNA inside energy-producing organ-elles called mitochondria is destroyed in a worm dad's sperm shortly after it fertilizes an egg, researchers report online June 23 in Science. A protein called CPS-6 cuts apart the mitochondrial DNA in the male sperm, blocking production of the proteins that ...

“Although cosmic rays were first detected 100 years ago, their origins have been a mystery,” says Holder. “One idea has been that they are produced by supernova explosions, but there was never any direct proof until now. This gamma ray measurement by VERITAS looks at a galaxy different ...
“While the main goals of this large-scale project were to understand the relationships of all flowering plant genera, it also sheds light on the timing of major events in the evolution of complex flower forms and life histories,” Dr. Michelangeli said. “Large analyses such as this can p...
BEIJING, Jan. 6 (Xinhua) -- Scientists have reported the high-quality genome sequence of blue-petal water lily, an ancient flowering plant, shedding new light on Charles Darwin's "abominable mystery". More than 300,000 species of flowering plants, also known as angiosperms, have emerged since...
we've learned bits and pieces about the hardware inside Microsoft's HoloLens augmented reality headset. But Microsoft's custom Holographic Processing Unit (HPU) has always posed something of a mystery. AtHot Chips this week, the company finally shed a little light on what its ...
ESA’s Solar Orbiter may have taken another step towards solving the eighty-year-old mystery of why the Sun’s outer atmosphere is so hot. On March 3, 2022, just a few months into Solar Orbiter’s nominal mission, the spacecraft’s Extreme Ultraviolet Imager (EUI) returned data showing ...

Barron reported that the group has used the technique not only on small chiral molecules such as CHFClBr, but also on biomolecules such as peptides, proteins, carbohydrates and nucleic acids. This gives a new perspective on their 3-D solution structure and dynamics. The work on CHFClBr/...
With ShadowCam, NASA can image permanently shadowed regions of the Moon in greater detail than previously possible, giving scientists a much better view of the lunar South Pole region. This area has never been explored by humans and is of great interest to science and exploration b...
