Most detailed 3D map ever of Milky Way includes nearly 2 billion stars

You can’t just drive a Google Maps car around the Milky Way to diagram it. It’s fortunate, then, that new information gathered by the European Space Agency’s Gaia observatory offers the most detailed map yet of the galaxy. The project’s map now includes almost 2 billion stars, and it helps the agency trace the Milky Way’s history.

“The new Gaia data promise to be a treasure trove for astronomers,” Jos de Bruijne, ESA’s Gaia deputy project scientist, said in a statement.

The new information not only brings the total number of stars mapped over seven years up to close to 2 billion, but it includes “a detailed census of more than 300,000 stars in our cosmic neighborhood,” meaning stars within 326 light-years of the sun. That 300,000 number is believed to be 92% of

Most detailed ever study of Greenland ice sheet warns of irreversible ice loss — ScienceDaily

In a study published this week in The Cryosphere, researchers from the National Centre for Atmospheric Science and University of Reading demonstrate how climate change could lead to irreversible sea level rise as temperatures continue to rise and the Greenland ice sheet continues to decline.

The massive ice sheet faces a point of no return, beyond which it will no longer fully regrow, permanently changing sea levels around the world.

The Greenland ice sheet is seven times the area of the UK, and stores a large amount of the Earth’s frozen water. At current rates of melting, it contributes almost 1mm to sea level per year, and accounts for around a quarter of total sea level rise.

Since 2003, despite seasonal periods of growth, Greenland’s ice sheet has lost three and a half trillion tonnes of ice.

Rising sea levels are one of the most severe effects of climate

Tagging produces detailed catalog of transcription factors key to making each cell type — ScienceDaily

A team of biomedical engineers at Duke University has created a new way to turn stem cells into a desired cell type by mastering the language of gene regulatory networks.

Programming stem cells into other cell types is not a new idea. Several methods already exist, but the results have left something to be desired. Often, programmed stem cells do not mature correctly when cultured in the lab, so researchers seeking adult neuron cells for an experiment might end up with embryonic neurons, which won’t be able to model late-onset psychiatric and neurodegenerative conditions.

“The cells might seem right at first glance,” said Josh Black, the Duke Ph.D. student who led the work in Charles Gersbach’s lab, “but they are often missing some of the key properties you want in those cells.”

Using CRISP gene editing, the lab led by Gersbach, The Rooney Family Associate Professor of Biomedical Engineering and

High-tech analyses of a U-boat and Nicaraguan freighter offer detailed glimpse into unexpected ‘islands of habitat’ — ScienceDaily

During a 2016 National Oceanic and Atmospheric Administration (NOAA) expedition to explore a pair of World War II shipwrecks that lie off the North Carolina coast, marine scientists ensconced within glass-domed submersibles navigated to the Atlantic Ocean seafloor in the hope of profiling the fish communities residing on the wrecks. Some of the findings of this joint ecological-archaeological undertaking were published this week in the Ecological Society of America’s journal Ecosphere.

The two ships, a German U-boat and a Nicaraguan freighter, had not been seen by humans since they sank nearly 80 years ago during the Battle of the Atlantic. “These World War II shipwrecks are important historical monuments, but are also valuable habitat for fish,” said Katrina Johnson, the paper’s first author and a senior at Bates College in Lewiston, Maine.

Johnson, who grew up spending summers on a small Connecticut island only accessible by boat, jumped at
