New mapping technique can help fight extreme poverty



Posted: 07 Dec 2017 03:25 PM PST


A new mapping technique shows how researchers are developing computational tools that combine cellphone records with data from satellites and geographic information systems to create timely and incredibly detailed poverty maps. Unlike surveys or censuses, which can take years and cost millions of dollars, these maps can be generated quickly and cost-efficiently.


Algae could feed and fuel planet with aid of new high-tech tool



Posted: 07 Dec 2017 11:18 AM PST


Vast quantities of medicines and renewable fuels could be produced by algae using a new gene-editing technique, a study suggests.


Heart monitors on wild narwhals reveal alarming responses to stress



Posted: 07 Dec 2017 11:17 AM PST


Stress from human disturbances could cause behavioral responses in narwhals that are inconsistent with their physiological capacities, researchers say. They found that narwhals released after entanglement in nets and outfitted with heart monitors performed a series of deep dives, swimming hard to escape, while their heart rates dropped to unexpectedly low levels of three to four beats per minute.


Hydropower dam energy without sacrificing Mekong food supply: New research offers solution



Posted: 07 Dec 2017 11:17 AM PST


Nearly 100 hydropower dams are planned for construction along tributaries off the Mekong River's 2,700-mile stretch. In a new article, researchers present a mathematical formula to balance power generation needs with the needs of fisheries downstream.


Researchers establish long-sought source of ocean methane



Posted: 07 Dec 2017 11:16 AM PST


A significant amount of the methane naturally released into the atmosphere comes from the ocean. This has long puzzled scientists because there are no known methane-producing organisms near the ocean's surface. A team of researchers has made a discovery that could help to answer this 'ocean methane paradox.'


Innovative system images photosynthesis to provide picture of plant health



Posted: 07 Dec 2017 08:48 AM PST


Researchers have developed a new imaging system that is designed to monitor the health of crops in the field or greenhouse. The new technology could one day save farmers significant money and time by enabling intelligent agricultural equipment that automatically provides plants with water or nutrients at the first signs of distress.


Forests are the key to fresh water



Posted: 07 Dec 2017 06:50 AM PST


Freshwater resources are critical to both human civilization and natural ecosystems, but researchers have discovered that changes to ground vegetation can have as much of an impact on global water resources as climate change.


Dust play significant role fertilizing mountain plants



Posted: 06 Dec 2017 02:42 PM PST


Researchers found foreign dust likely fertilizes plants in many locations worldwide.


West coast earthquake early warning system continues progress toward public use



Posted: 06 Dec 2017 01:23 PM PST


A decade after beginning work on an earthquake early warning system, scientists and engineers are fine-tuning a US West Coast prototype that could be in limited public use in 2018.


Head start through human intervention: Study on the spread of European plant species on other continents



Posted: 06 Dec 2017 09:25 AM PST


A new study has investigated the spread of European plant species on other continents.


Physicists propose a new method for monitoring nuclear waste



Posted: 06 Dec 2017 09:25 AM PST


New scientific findings suggest neutrino detectors may play an important role in ensuring better monitoring and safer storage of radioactive material in nuclear waste repository sites.


'Stressed out' cocoa trees could produce more flavorful chocolate



Posted: 06 Dec 2017 09:19 AM PST


Most people agree that chocolate tastes great, but is there a way to make it taste even better? Perhaps, according to scientists who looked at different conditions that can put a strain on cocoa trees. They say that although the agricultural method used to grow cocoa trees doesn't matter that much, the specific weather conditions do. 


Timing of migration is changing for songbirds on the Pacific coast



Posted: 06 Dec 2017 06:06 AM PST


Changes in the timing of birds' migration can have serious negative effects if, for example, they throw the birds out of sync with the food resources they depend on. A new study uses a long-term dataset from the Pacific coast and shows that the timing of bird migration in the region has shifted by more than two days in both spring and fall over the past two decades.
