Endocytosis, a fundamental process that cells use to take in macromolecules, functions a lot like an airlock on a spaceship -- but squishier, says a researcher. Researchers have studied how cells initiate and perform endocytosis since the 1960s, but in a new article they finally describes how cells shut down this important cellular machinery. And their findings are not without controversy.
'Hyperhotspots' could predict skin cancer risk

Scientists report the discovery of 'hyperhotspots' in the human genome, locations that are up to 170-times more sensitive to ultraviolet radiation (UV) from sunlight compared to the genome average.
Mysteries behind interstellar buckyballs finally answered

Cardiologists and physicists have developed a machine learning algorithm to predict the life expectancy in heart failure patients.
After visiting asteroid, Japan’s Hayabusa 2 probe heads back to Earth with samples
Japan's Hayabusa 2 spacecraft and its science team bid a bittersweet farewell to the asteroid Ryugu, 180 million miles from Earth, and began the months-long return trip to Earth with a precious set of samples. "This is an emotional moment!" the team tweeted on Tuesday. “It's sad to say goodbye to Ryugu,” project manager Yuichi Tsuda said at the Japan Aerospace Exploration...
Mysteries behind interstellar buckyballs finally answered
Scientists have long been puzzled by the existence of so-called "buckyballs"—complex carbon molecules with a soccer-ball-like structure—throughout interstellar space. Now, a team of researchers from the University of Arizona has proposed a mechanism for their formation in a study published in the Astrophysical Journal Letters.
When reporting climate-driven human migration, place matters
A quick Google search for "What is driving migration from Central America?" reveals that nearly all of the top hits claim climate change as a major catalyst for the mass movement of people out of their home countries. University of Arizona climate researchers, however, have shown that the reality is much more nuanced.
Maybe banking culture doesn't always make people dishonest
Scientists say they were unable to confirm a highly publicized 2014 study that suggested banking culture can promote dishonesty.
When reporting climate-driven human migration, place matters

Location matters when talking about how climate might or might not be driving migration from Central America. Climate research in the dry corridor region revealed a complex pattern of change. If you average across the entire region you wouldn't see a trend going either way.
Multimaterial 3D printing manufactures complex objects, fast

3D printing is super cool, but it's also super slow -- it would take 115 days to print a detailed, multimaterial object about the size of a grapefruit. A new method allows printing with up to 8 different inks in a fraction of the time, thanks to special printheads that can seamlessly switch inks up to 50 times per second.
