NASA has estimated rainfall from the Pineapple Express over the coastal regions southwestern Oregon and northern California from the series of storms in February, 2017.The West Coast is once again feeling the effects of the "Pineapple Express." Back in early January one of these "atmospheric river" events, which taps into tropical moisture from as far away as the Hawaiian Islands, brought heavy rains from Washington state and Oregon all the way down to southern California. This second time around, many of those same areas were hit again. The current rains are a result of three separate surges of moisture impacting the West Coast. The first such surge in this current event began impacting the Pacific coastal regions of Washington, Oregon, and northern California on February 15. 

What if walking three hours to get water was a first-world problem?

Three decades ago, a massive stellar explosion sent shockwaves not only through space but also through the astronomical community. SN 1987A was the closest observed supernova to Earth since the invention of the telescope and has become by far the best studied of all time, revolutionising our understanding of the explosive death of massive stars.

Spring is coming sooner to some plant species in the low Arctic of Greenland, while other species are delaying their emergence amid warming winters. The changes are associated with diminishing sea ice cover, according to a study published in the journalBiology Letters and led by the University of California, Davis.The timing of seasonal events, such as first spring growth, flower bud formation and blooming, make up a plant’s phenology — the window of time it has to grow, produce offspring and express its life history. Think of it as “nature’s clock.”

Antarctica’s Pine Island Glacier lost another large chunk of ice at the end of January. The section of ice that broke off the glacier on the western coast of Antarctica was roughly the size of Manhattan. It was 10 times smaller than the piece the same glacier sloughed in July 2015.

Cats, you might have heard, cause schizophrenia. Or—more recently—they do nothing of the sort. It’s a decades-long scientific investigation, infrequently punctuated by headline-grabbing stories that definitively claim one or the other, depending on whatever the newest sliver of research indicates.

Researchers from 20 of the world’s leading oceanographic research centers today warned that the world’s largest habitat – the deep ocean floor – may face starvation and sweeping ecological change by the year 2100.

Scientists at York University and a national team of collaborators have developed new mathematical models that will help researchers, doctors and policymakers address the challenging public health issue of antibiotic resistance in bacteria. The research, co-led by postdoctoral fellows Josie Hughes and Xi Huo, was published in the journal PLOS ONE.

For the first time a “tipping point” molecular link between the blood sugar glucose and Alzheimer’s disease has been established by scientists, who have shown that excess glucose damages a vital enzyme involved with inflammation response to the early stages of Alzheimer’s.

The Centre Valbio research station, a modern building of stone and glass set in the jungled hills at the edge of Madagascar’s Ranomafana National Park, was starting to look like the third season of The Wire. Big tackboards lined the walls, each one covered with dozens of pinned-up photographs. Some images were grouped together in families, while others floated alone, unconnected. It was 2012, and Rachel Jacobs was using Detective McNulty-style tactics to sort out the associations in a very different kind of crew: the park’s population of red-bellied lemurs.
