| Wind farms can provide society a surplus of reliable clean energy Posted: 20 Mar 2014 11:08 AM PDT Researchers have found that the wind industry can easily afford the energetic cost of building batteries and other grid-scale storage technologies. However, for the solar industry, scientists found that more work is needed to make grid-scale storage energetically sustainable.  |
| New approach makes cancer cells explode Posted: 20 Mar 2014 09:19 AM PDT Researchers have discovered that a substance called Vacquinol-1 makes cells from glioblastoma, the most aggressive type of brain tumor, literally explode. The established treatments that are available for glioblastoma include surgery, radiation and chemotherapy. But even if this treatment is given the average survival is just 15 months. It is therefore critical to find better treatments for malignant brain tumors.  |
| Moon of Saturn: Surface of Titan sea is mirror smooth Posted: 20 Mar 2014 07:15 AM PDT The surface of Ligeia Mare, Titan's second largest sea, has a mirror-like smoothness, possibly due to a lack of winds, geophysicists say. As the only other solar system body with an Earth-like weather system, Titan could serve as a model for studying our own planet's early history.  |
| Eyes are windows to the soul -- and evolution Posted: 20 Mar 2014 07:06 AM PDT Why do we become saucer-eyed from fear and squint from disgust? These near-opposite facial expressions are rooted in emotional responses that exploit how our eyes gather and focus light to detect an unknown threat, according to a new study.  |
| Bees capable of learning feats with tasty prize in sight Posted: 18 Mar 2014 11:25 AM PDT Bumblebees are capable of some remarkable learning feats, especially when they might get a tasty reward, according to two studies. In the first study, the researchers found bees capable of learning to solve increasingly complex problems, an example of scaffold learning. In a second study, the researchers found bees learned by watching and communicating with other bees, a process called social learning.  |
| New heart failure symptom: Shortness of breath while bending over Posted: 18 Mar 2014 09:46 AM PDT A novel heart failure symptom in advanced heart failure patients has been identified by cardiologists: shortness of breath while bending over, such as when putting on shoes. The condition, which cardiologists named "bendopnea" (pronounced "bend-op-nee-ah"), is an easily detectable symptom that can help doctors diagnose excessive fluid retention in patients with heart failure, according to the findings.  |
| Climatologists offer explanation for widening of Earth's tropical belt Posted: 18 Mar 2014 08:38 AM PDT Climatologists posit that the recent widening of the tropical belt is primarily caused by multi-decadal sea surface temperature variability in the Pacific Ocean. This variability includes the Pacific Decadal Oscillation (a long-lived El Niño-like pattern of Pacific climate variability) and anthropogenic pollutants, which act to modify the Pacific Decadal Oscillation. Until now there was no clear explanation for what is driving the widening.  |
| New view of supernova death throes in 3-D Posted: 18 Mar 2014 08:36 AM PDT A powerful, new three-dimensional model provides fresh insight into the turbulent death throes of supernovas, whose final explosions outshine entire galaxies and populate the universe with elements that make life on Earth possible. It shows how the turbulent mixing of elements inside stars causes them to expand, contract, and spit out matter before they finally detonate.  |
| Three quarters of people with seasonal, pandemic flu have no symptoms Posted: 16 Mar 2014 05:32 PM PDT Around 1 in 5 of the population were infected in both recent outbreaks of seasonal flu and the 2009 H1N1 influenza pandemic, but just 23% of these infections caused symptoms, and only 17% of people were ill enough to consult their doctor. These findings come from a major new community-based study comparing the burden and severity of seasonal and pandemic influenza in England over 5 years.  |
| How Were The Egyptian Pyramids Built? Posted: 28 Mar 2008 07:43 AM PDT The Aztecs, Mayans and ancient Egyptians were three very different civilizations with one very large similarity: pyramids. However, of these three ancient cultures, the Egyptians set the standard for what most people recognize as classic pyramid design: massive monuments with a square base and four smooth-sided triangular sides, rising to a point. The Aztecs and Mayans built their pyramids with tiered steps and a flat top.  |
