Few natural sights are revered as much as the aurora borealis, and scientists at NASA are hoping that two new rocket missions will help illuminate the processes that lead to such a magnificent light display. The two missions, with launch windows that opened January 21, 2025, are aiming for the Alaskan night sky, where auroras shine regularly during the winter. Auroras are byproducts of the interaction between solar wind and the Earth’s magnetosphere, containing its magnetic field. Following a ...read more

How is music changing over time? On one scale, it’s easy to see how music evolved through the ages as baroque music was displaced by classical, romantic and then modern music. In the 20th century alone, jazz, country and western, rock’n’roll all emerged along with pop, rap, hip hop and so on. Much of this rapid rate of change was driven by new ways of composing, experiencing and sharing music via vinyl, cassettes, CDs and mp3s. The emergence of digital streaming platforms, social networks ...read more

Time alone might be voluntary or involuntary; it might be pleasant or unpleasant. It all depends on the context. So, solitude is not necessarily bad, but is it beneficial? Nguyen is the principal investigator of Solitude Lab, where she and her team work to unravel these kinds of mysteries. They’ve found that solitude offers at least t ...read more

For adults of a certain age, dental implant advertisements appear ubiquitous. But the price — at potentially thousands of dollars per tooth — might, for many people be a case of financially biting off more than they can chew.What if, instead, they could regrow their pearly whites, perhaps at a fraction of the cost?Approaches that replace — rather than patch up — teeth with crowns or fillings may be closer than you think. Scientists have been exploring multiple methods in the past few dec ...read more

We can now track the spread of humanity by following a trail of blood…types.A group of researchers did just that, by analyzing genetic information from three groups of Early Man — most recently Neanderthal and Homo sapiens (earlier work also included Denisovans, an extinct subspecies that roamed Asia until about 30,000 years ago).Although their analysis, which appears in Scientific Reports, stretches back about 120,000 years ago, it also offers some implications for current medicine and heal ...read more
