Mystery of purple lights in sky solved with help from citizen scientists

Notanee Bourassa knew that what he was seeing in the night sky was not normal. Bourassa, an IT technician in Regina, Canada, trekked outside of his home on July 25, 2016, around midnight with his two younger children to show them a beautiful moving light display in the sky—an aurora borealis. He often sky gazes until the early hours of the morning to photograph the aurora with his Nikon camera, but this was his first expedition with his children. When a thin purple ribbon of light appeared and starting glowing, Bourassa immediately snapped pictures until the light particles disappeared 20 minutes later. Having watched the northern lights for almost 30 years since he was a teenager, he knew this wasn't an aurora. It was something else.

Kepler spacecraft nearing the end as fuel runs low

Trailing Earth's orbit at 94 million miles away, the Kepler space telescope has survived many potential knock-outs during its nine years in flight, from mechanical failures to being blasted by cosmic rays.

Molecular brakemen keep transporter proteins in check until it's their turn to move

Within both plant and animal cells, motor proteins act like the engines in a busy train system. They shuttle material in the cell from one location to another. And just as commuter trains travel a predictable route in a defined direction, their volume of transport is commensurate with need. At rush hour, more trains are in operation. At midnight, there's no point in running trains every 10 minutes.

An international collaboration between researchers at the University of Copenhagen, Nagoya University and the University of Western Australia has resulted in a plant biology breakthrough. Since 2014, the researchers have worked on identifying the genetic background for the improved flood tolerance observed in rice, wheat and several natural wetland plants. In New Phytologist, the researchers describe the discovery of a single gene that controls the surface properties of rice, rendering the leaves superhydrophobic.

A new twist to an old story of cellular signaling in the eye of a fly

When light falls on the eye of a fly, ripples of messages flow through its cells. These messages are carried by molecular messengers forming an intricate information system that exists in most living cells.

First tracking of yellow-eyed penguin juveniles to learn more about survival rates

A select group of this season's yellow-eyed penguin/hoiho chicks are having their first expeditions into the ocean remotely tracked, as University of Otago researchers investigate dramatically declining survival rates of the endangered species.

Cutting and leaving invasive western juniper may lead to increase in invasive grasses

The spread of western juniper and invasive grasses are major threats to the health of the sagebrush-steppe ecosystem.

Small birds discern threat level of enemies

Chickadees and titmice don't just see that another bird is dangerous. They can also differentiate species and tell just how much of a threat they are.

Climate change is shrinking mountain hares' habitat in the Alps

A warming climate will shrink and fragment mountain hare habitat in the Swiss Alps. Populations are likely to decline as a result, concludes an international study led by the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) and the University of Bern.

Scientists remind their peers: Female birds sing, too

When North American ornithologists hear a bird singing, they're likely to assume it's a male. But in many species, the females sing too—and a new commentary in The Auk: Ornithological Advances argues that a better understanding of these unappreciated female songs could lead to advances in many aspects of bird biology.

'Cold-blooded' pythons make for caring moms

Reptiles are usually thought of as cold-blooded (an outdated term), simple animals that certainly don't care for their young.

A brewer's tale of proteins and beer

The transformation of barley grains into beer is an old story, typically starring water, yeast and hops. Now, in a report in the Journal of Proteome Research, scientists are highlighting another character in this tale: proteins. The results could someday lead to a better, tastier brew.

'Lazy lawn mowers' can help support suburban bee populations and diversity

Homeowners concerned about the decline of bees, butterflies and other pollinating insects need look no further than their own back yards, says ecologist Susannah Lerman at the University of Massachusetts Amherst and the USDA Forest Service. In new research, she and colleagues suggest that homeowners can help support bee habitat in suburban yards, specifically their lawns, by changing lawn-mowing habits.

Researchers say 'active protection' needed to help Angola's threatened elephants

A new study of African savannah elephant populations in Angola by wildlife ecologists from Elephants Without Borders (EWB) and the University of Massachusetts Amherst reports today that though the population seemed to be recovering after the war ended there, that trend has now reversed, underlining "the need to be vigilant against poaching and habitat loss," says first author Scott Schlossberg.

Tradeoffs between weaponry and fecundity in snapping shrimp queens vary with eusociality

Amongst species of colonial snapping shrimp, the capacity for defense versus reproduction in queens varies with the level of cooperation, according to a study published March 14, 2018 in the open-access journal PLOS ONE by Sally Bornbusch from Duke University and colleagues.

Interactive, downloadable and 3-D printable scans of newly discovered hermit crabs now available

Today, a study published in the open access, open data journal GigaScience provides three-dimensional visual data from hermit crabs using the latest 3D microCT (Micro computed tomography) scanning technology. By making this microCT data publicly available, taxonomists potentially have more time and cost-efficient options for examining and comparing specimens for taxonomic research. With a shortage of trained taxonomists, this also provides new opportunities for education and training. To ease access to these data, the authors go beyond just describing the data collection and findings by providing downloadable, interactive files of everything in this study. For interested citizen scientists out there, they even include interactive web-based viewers and 3D printable file formats. The work here highlights new ways for researchers to share complex data without having to send out precious samples that can be damaged or lost.
