Monitoring lava lake levels in Congo volcano



Posted: 15 May 2018 03:09 PM PDT


Nyiragongo in the Democratic Republic of the Congo is among the world's most active volcanoes, with a persistent lava lake as one of its defining features.


Savanna chimpanzees suffer from heat stress



Posted: 15 May 2018 10:15 AM PDT


An international team of scientists has studied the physiological parameters of savanna and rainforest chimpanzees and compared their water and energy budgets as well as their stress levels. They found that the stress of maintaining their body temperature is a tremendous burden on chimpanzees living in the savanna.


Tiny satellite's first global map of ice clouds



Posted: 15 May 2018 08:35 AM PDT


Looking at Earth from the International Space Station, astronauts see big, white clouds spreading across the planet. They cannot distinguish a gray rain cloud from a puffy white cloud. While satellites can see through many clouds and estimate the liquid precipitation they hold, they can't see the smaller ice particles that create enormous rain clouds.


New approach to global-warming projections could make regional estimates more precise



Posted: 15 May 2018 08:35 AM PDT


A new method for projecting how the temperature will respond to human impacts supports the outlook for substantial global warming throughout this century - but also indicates that, in many regions, warming patterns are likely to vary significantly from those estimated by widely used computer models.


Wasps drum to alert one another of food nearby



Posted: 15 May 2018 08:35 AM PDT


New research shows wasps have their own way of communicating to each other about mealtimes -- drumming on their gaster (or abdomen) to let each other know that there's food nearby. For nearly five decades, researchers thought the gastral drumming was a signal of hunger. These findings are the first evidence that wasps have complex communication about food, just as ants, bees, termites, and other social insects.


Carbon-recycling system: Two-electron chemical reactions using light energy, gold



Posted: 15 May 2018 07:57 AM PDT


Scientists are one step closer to building a carbon-recycling system that can harvest solar energy to efficiently convert CO2 and water into liquid fuels. By optimizing many parts of the system, the researchers say, they can now drive two-electron chemical reactions, a substantial advance over one-electron reactions, which are energy inefficient.


Impact of weather and well-timed cultural management techniques on organic weed control



Posted: 15 May 2018 07:57 AM PDT


Weed management can be a tough challenge in organic cropping systems since growers don't have herbicides in their weed control arsenal. New research, though, shows that weather conditions and well-timed cultural management techniques can help fill the void by making crops more competitive.


Researchers use LiDAR to locate invasive fish and preserve a national treasure



Posted: 15 May 2018 07:57 AM PDT


According to new research, an aircraft-mounted instrument could offer a faster way to locate and capture the non-native fish at Yellowstone National Park during the brief weeks each year when they come into shallow water to spawn.


Monitoring the tremble -- and potential fall -- of natural rock arches



Posted: 15 May 2018 07:57 AM PDT


Scientists monitoring the vibrations of natural rock arches have found that the resonant frequencies of arches undergo dynamic changes from day to day, according to new research.


Prized data, free and open to all



Posted: 15 May 2018 07:56 AM PDT


The first official account of the electronic Rothamsted Archive and what it offers, highlights how this unique historical repository of agricultural and meteorological data, which date back to 1843, is the result of some remarkable forward thinking.


Antarctic seals can help predict ice sheet melt



Posted: 15 May 2018 07:56 AM PDT


Two species of seal found in Antarctic seas are helping scientists collect data about the temperature and salinity of waters around vulnerable ice sheets in West Antarctica. Understanding more about how this water gets towards the ice shelves by measuring its temperature, salinity and depth, will help climate change modellers make more accurate predictions about how rapidly the Antarctic ice sheet is melting.


Scientists develop method to tweak tiny 'antenna' on cells



Posted: 15 May 2018 07:56 AM PDT


Scientists say they have found a fast way to manipulate a cell's cilia, the tiny, fingerlike protrusions that 'feel' and sense their microscopic environment. The experiments, performed in mouse cells, may advance scientists' efforts to not only understand how the nano-sized antennae work, but also how to repair them.


Insurance industry dangerously unprepared for extreme weather, study finds



Posted: 15 May 2018 05:17 AM PDT


As historic flooding caused by climate change devastates communities in New Brunswick and British Columbia, new research reveals the insurance industry hasn't considered a changing climate in their practices, putting homeowners at financial risk.


Wildfires may cause long-term health problems for endangered orangutans



Posted: 15 May 2018 05:17 AM PDT


Orangutans, already critically endangered due to habitat loss from logging and farming, may face another threat in the form of smoke from natural and human-caused fires, a new study finds.


Rhino horn used to comfort the terminally ill in Vietnam



Posted: 14 May 2018 06:55 AM PDT


From treating cancer and erectile dysfunction to managing hangovers, the horns of endangered wild rhinoceros are widely used as a medical cure-all in parts of Asia. A new study uncovers new reasons for why Vietnamese consumers buy illegal rhino horn. This knowledge can now be used in campaigns to save endangered rhinoceros.


Location of protected areas vital to wildlife survival



Posted: 14 May 2018 06:15 AM PDT


A new study, by conservation scientists and environmental scholars, say the exact location of protective wild spaces is just as vital as committing to set these areas aside.
