How heavy is dark matter? Scientists radically narrow the potential mass range for the first time
Scientists have calculated the mass range for Dark Matter - and it's tighter than the science world thought. (2021-01-27)

Protected areas help waterbirds adapt to climate change
Climate change pushes species distribution areas northward. However, the expansion of species ranges is not self-evident due to e.g. habitat degradation and unsustainable harvesting caused by human activities. A new study led from the University of Turku, Finland, suggests that protected areas can facilitate wintering waterbird adaptation to climate warming by advancing their range shifts towards north.

Breakthrough in battle against invasive plants
Plants that can 'bounce back' after disturbances like ploughing, flooding or drought are the most likely to be 'invasive' if they're moved to new parts of the world, scientists say. (2019-12-06)

New tech improves ability to reflect sound back to its source
Researchers have developed a device that reflects sound in the direction it came from, rather than deflecting it at an angle. The 'retroreflector' can reflect sound across an operating range of 70 degrees in either direction -- more than doubling the effective range of previous technologies. (2018-06-26)

Alien honeybees could cause plant extinction

Even 'healthy' weight gain raises pregnancy diabetes risk
Mothers who gain weight in the years leading up to pregnancy have an increased risk of gestational diabetes. Women gaining more than 2.5 percent of their body weight each year tripled their risk of gestational diabetes compared to women who maintained a stable weight. This risk doubled for women with a small weight gain (1.5 to 2.5 percent). Even women with small weight gains within the healthy BMI range doubled their risk of gestational diabetes. (2017-04-04)

Many North American birds may lose part of range under climate change scenarios
Over 50 percent of nearly 600 surveyed bird species may lose more than half of their current geographic range across three climate change scenarios through the end of the century in North America. (2015-09-02)

Warmer climates may increase pesticides' toxicity in fish
In a study of the effects of increasing climate temperatures on the toxicity of three contaminants in different fish species, researchers found that all pesticides and industrial contaminants studied became toxic. (2015-06-01)

Hitting the borders of expansion
IST Austria scientists research how population size and genetic drift affect the limits to a species' range. Jitka Polechová and Nick Barton explain in this week's edition of PNAS why sharp range margins arise in natural populations. (2015-05-05)

How much sleep do we need?
An expert panel that examined data from 320 studies is recommending new guidelines on how much sleep people should get. The guidelines are based on age, ranging from newborns (who need 14 to 17 hours of sleep per day) to adults aged 65 and up (7 to 8 hours per day). (2015-02-11)

Researchers take big-data approach to estimate range of electric vehicles
Researchers have developed new software that estimates how much farther electric vehicles can drive before needing to recharge. The new technique requires drivers to plug in their destination and automatically pulls in data on a host of variables to predict energy use for the vehicle. (2014-10-21)

Scientists find ancient mountains that fed early life
Scientists have found a huge mountain range in Gondwana, 600 million years ago. It ran from modern west Africa to northeast Brazil, and as it eroded it fed the oceans with nutrients that fueled an explosion of early life on Earth. (2014-10-16)

Electric vehicle consumers better off with electric range under 100 miles: INFORMS study
Until battery cost is cut down to $100 per kilowatt hour, the majority of US consumers for battery electric vehicles will be better off by choosing an electric vehicle with a range below 100 miles, according to a new study in the Articles in Advance section of Transportation Science, a journal of the Institute for Operations Research and the Management Sciences. (2014-08-18)

Dolby licenses Max Planck imaging technology
Dolby Laboratories acquires usage rights to innovative imaging patent portfolio from the Max Planck Institute for Informatics. (2013-08-01)

Why is it easier to lose 2-4 pounds rather than 3 pounds?
Consumers are more likely to pursue goals when they are ambitious yet flexible, according to a new study in the Journal of Consumer Research. (2013-06-18)

Researchers find local wildlife protection safeguards entire range
Researchers have analyzed historical range maps for 47 mammal species to find patterns that might help conservationists assess threats to animal populations from human encroachment. According to the authors, an animal's habitable range contains different ecological niches that can provide valuable clues about the species resiliency. Local environmental factors such as temperature and precipitation can influence how animals within the same species respond to disruptions to their habitats. (2011-02-22)

'Fowl' news: Hints from Taiwan that free-range eggs may be less healthy than regular eggs
Contrary to popular belief, paying a premium price for free-range eggs may not be healthier than eating regular eggs, a new study reports. Scientists found that free-range eggs in Taiwan contain at least five times higher levels of certain pollutants than regular eggs. Their findings appear in ACS' biweekly Journal of Agricultural and Food Chemistry. (2010-06-16)

Final rocket launches, measures aurora movement
It's been a long wait, but it was worth it. The Black Brant XII sounding rocket with the CASCADES II experiment launched and flew through an active aurora display March 20 at 3:04 a.m. Alaska Daylight Time. The successful launch occurred after 20 nights of preparing and then waiting to launch the NASA rocket. The CASCADES II team needed very specific conditions and clear weather for an optimal launch.
