Impressions from ancient clay seals found at a small site in Israel east of Gaza are signs of government in an area thought to be entirely rural during the 10th century B.C. This could indicate that Biblical accounts of David and his son Solomon described real kings rather than the backwater chieftains considered more likely by some archaeologists.
New video recorded during the return of NASA’s Orion through Earth’s atmosphere this month provides a taste of the intense conditions the spacecraft, and the astronauts it carries, will endure when they return from deep space destinations on the journey to Mars.
Reconstructing what extinct organisms fed on can be a real challenge. But, a study of tooth enamel in mammals living today in the equatorial forest of Gabon could ultimately shed light on the diet of long extinct animals, according to new research.
Research has shown that modern human skeletons evolved into their lightly built form only relatively recently— after the start of the Holocene about 12,000 years ago and even more recently in some human populations. The work revealed a higher decrease in the density of lower limbs, suggesting that the transformation may be linked to humans' shift from a foraging lifestyle to a sedentary agricultural one.
Residents of the Northern Hemisphere, don’t worry about the winter solstice– it’s not the middle of winter and, in some places, it’s not even the start of wintry weather. So why exactly is the shortest day of the year so distant from the coldest temperatures?
You may think your e-reader is helping you get to sleep at night, but it might actually be harming your quality of sleep. Exposure to light at night suppresses release of the sleep-facilitating hormone melatonin and shifts the circadian clock, making it harder to fall asleep at bedtime. The devices emit light that is short-wavelength-enriched light, which has a higher concentration of blue light than natural light.
As you celebrate the end of the year in the warmth of your home, spare a thought for the organisms riding with a third-class ticket on the International Space Station– bolted to the outside with no protection against open space.
A bacterium has been used to wish people a Merry Xmas. Grown by a professor, the letters used to spell MERRY XMAS are made of Bacillus subtilis, a non-pathogenic bacterium that is found in soil and the human gut.
The first kidney transplant was performed on June 17, 1950, however the kidney was rejected only 10 months later. At the time there were no antirejection drugs. The first successful transplant was carried out using identical twins on Dec. 23, 1954.
Asbestos waste spills in a gray gash down the flank of a lush green hill above tribal villages in eastern India. Three decades after the mines were abandoned, nothing has been done to remove the enormous, hazardous piles of broken rocks and powdery dust left behind.
Numerous factors influence how much power wind turbines generate. Now, researchers have described how much of an effect they believe the crops planted below the turbines matter. Corn, a tall crop, slows down the wind more than soybeans, which are shorter.
There has been a steady increase in the number of children who become short-sighted over recent decades. One aspect of modern life that may be partly to blame is the reducing amount of time we spend outdoors during childhood. But, new research suggests that children with low levels of vitamin D in their blood are not at increased risk of developing myopia.
The study of the human brain has progressed in the last decade, and with the important research and the publication of a key paper by Karl Deisseroth, great progress has been made in the pace of development. For that work, and the development of CLARITY, a new method that allows full brain imaging and molecular analysis, he was recently honored at the R&D 100 awards event as the “Scientist of the Year.”
With 2014 marking the 45th anniversary of Neil Armstrong’s historic first step on the moon, NASA outlined plans for America's next giant leap in space exploration— to send astronauts to Mars.
CPC’s BQ45GL series of caps provides three options for quick disconnect couplings to meet various needs. Adding quick disconnects to media bottles enhances the user experience by making it easier to exchange consumable products.
