Genetic Super Tomatoes

Humans have been grafting plants onto other plants for thousands of years, but only in the last few generations have we understood the genetic implications of the technique. Researchers from Penn State and the University of Florida partnered with a Nebraska startup to combine genetically “stressed” roots with regular tomato …

Organic Matter And Water

An international team of scientists has studied both the water and organic contents from a dust particle recovered from the surface of the near-Earth S-type asteroid 25143 Itokawa by JAXA’s Hayabusa mission, which was the first mission that brought pristine asteroidal materials to Earth. The S-type asteroid Itokawa. Image credit: …

Sequence Mitochondrial

Scientists have extracted and sequenced mitochondrial DNA from a partial femur of an ancient dog that lived in Alaska 10,150 years ago. Their results, published in the Proceedings of the Royal Society B, demonstrate that the animal belonged to a lineage of dogs that diverged from Siberian dogs around 16,700 …

Microbial Life

A team of geobiologists from Germany has found biologically-relevant primordial organic molecules and gases in fluid inclusions trapped in 3.5-billion-year-old barites from the Dresser mine, Marble Bar, Australia. Location of the Dresser mine in Western Australia (a) and black barite associated with originally sulfidic stromatolites at the sampling site (b) …

Old Mammoth DNA

An international team of scientists has sequenced and analyzed DNA from three mammoth specimens, two of which are more than one million years old. The results show that two distinct mammoth lineages were present in eastern Siberia during the Early Pleistocene; one of these lineages gave rise to the woolly …

Caffeine During Pregnancy

Caffeine consumed during pregnancy can change important brain pathways that could lead to behavioral problems later in life, according to new research from the Del Monte Institute for Neuroscience at the University of Rochester Medical Center. Caffeine is a known neuromodulator that is commonly consumed throughout pregnancy. Image credit: Poohchisa …

Quadruple Helix DNA

A team of scientists from the United Kingdom and Spain has demonstrated that a technique called fluorescence lifetime imaging microscopy in conjunction with a fluorescent probe can identify four-stranded ‘quadruple helix’ DNA structures within nuclei of live cells. Fluorescence lifetime imaging microscopy map of nuclear DNA in live cells stained …

Quantum Teleportation

Quantum teleportation is essential for many quantum information technologies, including long-distance quantum networks. Using fiber-coupled devices, including state-of-the-art low-noise superconducting nanowire single-photon detectors and off-the-shelf optics, scientists from Fermilab, Caltech, ATT, NASA’s Jet Propulsion Laboratory, the University of Calgary, and Harvard University have demonstrated sustained, long-distance (44 km of fiber) …

Discover Abyssal Depths

Marine biologists from the United States and the United Kingdom have recorded over 100 deep water-dwelling cutthroat eels, identified as Ilyophis arx, at a 1 kg bait package deployed on an abyssal seamount summit in the southwestern Clarion-Clipperton Zone in the central Pacific Ocean. This is the highest number of …
