New research indicates when the boss puts employees’ needs over his or her own, measureable improvements in customer satisfaction, higher job performance by employees, and lower turnover are the result. The study suggests this is an increasingly relevant form of leadership that offers promise to the premise that if businesses lead by caring for their people, the profits will take care of themselves. —> Read More
The carnivorous penis worm, or Ottoia, known from 500-million-year-old fossils, was a fearsome beast: it could turn its mouth inside out to reveal a tooth-lined throat that looked like a cheese grater. Because its teeth are less than a millimeter in size, researchers used high-powered microscopes to find out more about their structure. —> Read More
About one-quarter of adults aged 65 years and older used mobility devices — such as canes, walkers, and wheelchairs — in 2011, and about a third of these reported using multiple devices. —> Read More
About one in nine people globally still suffer from hunger with the majority of the hungry living in Africa and Asia. The world’s forests have great potential to improve their nutrition and ensure their livelihoods. In fact, forests and forestry are essential to achieve food security as the limits of boosting agricultural production are becoming increasingly clear. —> Read More
It sounds like something out of a horror movie: a penis-shaped worm which was able to turn its mouth inside out and drag itself around by its tooth-lined throat, which resembled a cheese grater. But a new study of the rather unfortunately-named penis worm has found that their bizarre dental structure may help in the identification of previously unrecognised fossil specimens from the time on Earth when animals were first coming into their own. —> Read More

A compound and an enzyme that occur naturally in cruciferous vegetables–cauliflower, cabbage, broccoli and Brussels sprouts–may help prevent recurrence and spread of some cancers, according to researchers. When they treated human cervical cancer stem cells with phenethyl isothiocyanate (PEITC) in a Petri dish, about 75 percent died within 24 hours using a 20-micromolar concentration of the compound. —> Read More
Ethanol fuel refineries could be releasing much larger amounts of some ozone-forming compounds into the atmosphere than current assessments suggest, a new study finds. Airborne measurements downwind from an ethanol fuel refinery in Decatur, Illinois, show that ethanol emissions are 30 times higher than government estimates. The measurements also show emissions of all volatile organic compounds, which include ethanol, were five times higher than government numbers, which estimate emissions based on manufacturing information. —> Read More
Researchers have found a way to make jet fuel from a common black fungus found in decaying leaves, soil and rotting fruit. The researchers hope the process leads to economically viable production of aviation biofuels in the next five years. —> Read More
A lava lake that sits within Halemaumau Crater on Hawaii’s Big Island exploded Sunday after a portion of the crater wall collapsed into the lava below.
The footage above, captured by U.S. Geological Survey cameras at the Hawaiian Volcano Observatory, shows the debris falling into the lake, triggering the fiery blast.
According to volcanologist Frank Trusdell, explosions like this one are unpredictable events. “The walls of the crater become destabilized by heating, weathering, earthquakes and loss of support. They fall into the lava causing degassing of the lava. The exsolution of gases happens rapidly, leading to the explosion,” he told The Huffington Post.
Typically, the lava within the lake is 100 feet to 200 feet below the rim, but recently the magma chamber that flows into the lava lake has shown increased inflation, suggesting that lava is being driven into the lake from an underground chamber below.
Visitors to Volcanoes National Park have been privy to a rare and impressive show, since the lava is now visible from the crater overlook and has overflowed several times onto the floor of Halemaumau crater.
Recent overflows are visible in this USGS photograph taken on April 30.
The lava lake stems from the Kilauea volcano, which makes up the southeastern tip of Hawaii island. The current summit eruption began in 2008.
While this explosion is considered small by USGS researchers, most people are thoroughly impressed.
