Twenty people die waiting for an organ transplant every day in the US, but lab-grown organs so far lack the cellular density, vasculature, and functions required to make them viable replacements. The new SWIFT method solves those problems by 3D printing vascular channel networks directly into living organ building blocks, enabling the creation of larger tissues approximating the size and function of organs, including heart tissue that beats on its own over a seven-day period.

India loses contact with Chandrayaan 2’s lander at climax of historic moon missionIndia's Mission Control lost contact with the lander for its Chandrayaan 2 mission today, just as it was about to make a touchdown near the moon's south pole. Chandrayaan 2's Vikram lander descended to a highland plain between two craters, Manzinus C and Simpelius N, at a latitude of 70.9 degrees south. But contact was lost in the final moments of the descent. During the minutes that followed, worried-looking mission managers huddled with Indian Prime Minister Narendra Modi, who was at Satish Dhawan Space Center for the landing. Then Kailasavadivoo Sivan, chairman of the Indian Space Research Organization, took the… Read More

For tens of millions of people, migration is a tough reality. What causes people to migrate away from their home countries, and what happens when they do? Migrants and their labor are responsible for moving hundreds of billions of dollars around the world annually. At their destinations, they affect populations, cultures, and economies. But their movement also has a major impact on the places they leave, including on how people use land.

The Dead Sea scrolls have given up fresh secrets, with researchers saying they have identified a previously unknown technique used to prepare one of the most remarkable scrolls of the collection.

Scientists say the study poses a puzzle, as the salts used on the writing layer of the Temple scroll are not common to the Dead Sea region.

First discovered in 1947 by Bedouin shepherds looking for a lost sheep, the ancient Hebrew texts known as the Dead Sea Scrolls are some of the most well-preserved ancient written materials ever found. Now, a study by researchers at MIT and elsewhere elucidates a unique ancient technology of parchment making and provides potentially new insights into methods to better preserve these precious historical documents.

Researchers studying how plants evolved the abilities to make natural chemicals, which they use to adapt to stress, have uncovered how an enzyme called chalcone isomerase evolved to enable plants to make products vital to their own survival. The researchers' hope is that this knowledge will inform the manufacture of products that are beneficial to humans, including medications and improved crops.
