Scientists have, for the first time, created a biosynthetic spider silk that behaves like the real thing. And they may soon make it even stronger.

Using data from NASA's Moon Mineralogy Mapper instrument, scientists have identified three specific signatures that definitively prove there is water ice at the surface of the Moon.

An international team has found the earliest and largest monumental cemetery in eastern Africa. The Lothagam North Pillar Site was built 5,000 years ago by early pastoralists living around Lake Turkana, Kenya. This group is believed to have had an egalitarian society, without a stratified social hierarchy. Thus their construction of such a large public project contradicts long-standing narratives that a stratified social structure is necessary to enable the construction of large public monuments.

New research boosts the case for quantum entanglement. Scientists have used distant quasars, one of which emitted its light 7.8 billion years ago and the other 12.2 billion years ago, to determine the measurements to be made on pairs of entangled photons. They found correlations among more than 30,000 pairs of photons -- far exceeding the limit for a classically based mechanism.

Deforestation is suspected to have contributed to the mysterious collapse of Mayan civilization more than 1,000 years ago. A new study shows that the forest-clearing also decimated carbon reservoirs in the tropical soils of the Yucatan peninsula region long after ancient cities were abandoned and the forests grew back.

A new Organ Chip system linked a Brain Chip with two blood-brain barrier (BBB) Chips to recapitulate the interactions between the brain and its blood vessels. This system reacts to methamphetamine exposure just like a human brain, and has allowed scientists to make new discoveries about just how important our blood vessels are for our mental function.

The West Coast of the United States is shrouded in smoke from the 110 large fires (this does not include smaller fires within each complex of fires) that have erupted across the region during this fire season.

Scientists have discovered that waves of migration from Anatolia and the Zagros mountains to the Levant helped develop the Chalcolithic culture that existed in Israel's Upper Galilee region some 6,500 years ago. "Certain characteristics, such as genetic mutations contributing to blue eye color, were not seen in the DNA test results of earlier Levantine human remains," according to one of the researchers.

Thin ribbons of purple and white light that sometimes appear in the night sky were dubbed a new type of aurora when brought to scientists' attention in 2016. But new research suggests these mysterious streams of light are not an aurora at all but an entirely new celestial phenomenon.
