1+ day, 2+ hour ago   (307+ words) Researchers from North Carolina State University and Johns Hopkins University have demonstrated a technology capable of a suite of data storage and computing functions -- repeatedly storing, retrieving, computing, erasing or rewriting data -- that uses DNA rather than conventional electronics. Previous…...

12+ hour, 30+ min ago   (594+ words) Scientists discovered that aging cells can use malfunctioning mitochondria to unlock inflammatory genes and keep the immune system stuck in a prolonged state of alert. Blocking one part of this process reduced inflammation and improved healthy aging in mice, suggesting…...

13+ hour ago   (691+ words) Mount Etna’s ancient eruptions followed radically different paths, with some magma lingering near the surface for weeks while other magma raced upward from nearly 30 kilometers deep in just hours. Scientists traced the difference to volcanic gases such as carbon dioxide…...

13+ hour, 39+ min ago   (663+ words) Scientists have found that Arctic cyclones become especially destructive when several strike one after another. These storm clusters cause about twice as much sea ice loss as isolated cyclones, with impacts that persist roughly two and a half times longer....

14+ hour, 37+ min ago   (635+ words) Sucralose, the artificial sweetener used in Splenda, came under scrutiny after a study found that a related chemical damaged DNA and weakened the gut barrier in laboratory experiments. But later findings have complicated that alarming picture....

1+ day, 2+ hour ago   (726+ words) Researchers at Carnegie Mellon University's School of Computer Science, the University of Pittsburgh School of Medicine and the University of Washington have uncovered a previously underexplored feature of Alzheimer's disease that may help scientists identify new avenues for treatment. To…...

1+ day, 3+ hour ago   (262+ words) A massive worldwide survey of physicists has revealed surprisingly little agreement about some of the universe’s biggest mysteries. No majority backed the standard cosmological model, a leading explanation for dark matter, or any single theory of quantum gravity. One area…...

1+ day, 3+ hour ago   (339+ words) Most men may be missing an important dietary clue about prostate cancer. A new survey found that only 20% knew research has linked dairy consumption with increased prostate cancer risk, while 66% said they would consider avoiding dairy after learning about the…...

1+ day, 4+ hour ago   (460+ words) The Indian and Pacific oceans have been climatically linked for centuries, but scientists say that connection is now breaking down in an exceptional way. Ancient climate records suggest volcanoes disrupted the relationship in the past, while today human-caused warming appears…...

1+ day, 4+ hour ago   (669+ words) Electron microscopes can reveal structures far smaller than anything visible with ordinary light. But researchers in Austria say conventional electron microscopes may be leaving valuable information on the table. In a standard system, electrons are mainly counted to build an…...
