Chinese researchers have improved the accuracy in detecting space junk in earth's orbit, providing a more effective way to plot safe routes for spacecraft maneuvers.
By introducing a chemical cocktail to granulosa cells, researchers in China induced the cells to transform into functional oocytes in mice. Once fertilized, these oocytes were then successfully able to produce healthy offspring, showing no differences from naturally bred mice. The chemical reprogramming method appears December 24 in the journal Cell Reports.
Scientists have developed a special molecular switch that could be embedded into gene therapies to allow doctors to control dosing. The feat offers gene therapy designers what may be the first viable technique for adjusting the activity levels of their therapeutic genes.
When Steve Ghan set out to walk 1,500 miles of the Pacific Crest Trail, he brought along a bright blue hat emblazoned with four words: "Make Earth Cool Again." It often drew compliments from other hikers, which he used as an opening.
Two-photon laser scanning microscopy imaging is commonly applied to study neuronal activity at cellular and subcellular resolutions in mammalian brains. Such studies are yet confined to a single functional region of the brain. In a recent report, Mengke Yang and colleagues at the Brain Research Instrument Innovation Center, Institute of Neuroscience, Center for Systems Neuroscience and Optical...
Typhoon Phanfone smashed into the central Philippines on Tuesday, leaving thousands of people unable to get home for the Christmas holidays and forcing many others to evacuate in the face of the onslaught.
Deaths due to famine have fallen precipitously in recent decades, but undernutrition, which affects one in five children worldwide, remains rampant. Now, researchers are using satellite imagery and social media to detect food-scarce regions before they become full-blown crises.
It's the most wonderful time of the year—the time NASA's SnowEx campaign hits the skies and ground of the world's snowy places, measuring snow properties to understand how much water is contained by each winter's snowfall.
Fortunately for today's scientists, Apollo-era leaders had the foresight to save much of the 842 pounds (382 kilograms) of Moon soil and rocks retrieved by NASA astronauts 50 years ago for future generations. They figured new crops of scientists, using instruments of their time, would be able to probe the samples with unprecedented rigor.
On solar farms in particularly dusty places in the world, like the Arabian Peninsula and parts of India and China, air pollution costs the solar energy industry tens of billions of dollars annually. As particles settle out of the air onto the surfaces of solar panels, they constrain the panels' potential. Workers with soapy brushes can clean the grime from the panels, much as you might clean your...
For most Americans, their home is their most valuable asset, so it makes sense to borrow against the equity to obtain cash. In lean times, that money can be spent on consumption, which keeps the economy humming along. But if housing values and personal incomes don't rise, borrowers might find themselves struggling to repay the debt.
An international team of researchers has concluded that the so-called "enigmatic hominoid" did not walk upright and was also not a tree climber. In their paper published in Proceedings of the National Academy of Sciences, the group describes their in-depth study of the skeletal remains of Oreopithecus bambolii and what they learned from it.
Randomness governs many things, from the growth of cell colonies and the agglomeration of polymers to the shapes of tendrils that form when you pour cream into a cup of coffee.
Based on the first data release (DR1) from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), astronomers have derived fundamental parameters of nearly 30,000 M-dwarf stars. The research paper presenting the findings was published December 13 on the arXiv pre-print repository.
