Hybrid Midsize Sedan?
August 25, 2011 12:43 PM - Kathleen Neil, Contributing Editor, ENN

There seem to be a lot of people looking for a quality, affordable, and safe midsize sedan, but a hybrid midsize sedan? Mingling with everyone at the Toyota 2012 Camry event at Paramount Studios Hollywood yesterday I’d have to say, the mainstream car world just isn’t that concerned about how green their drive is at this point. The economy isn't helping, nor is the way most people are experiencing the modern electronic world as a bad case of button overload; and general interest in iconic brands like a Prius Hybrid or a Chevy Volt is limited. In the last two years my automotive interest has been focused on hybrids and electric vehicles. Yesterday in Hollywood I drove both the hybrid 2012 Camry and the non-hybrid 2012 Camry and I got to look more closely at the interface between the car most people are looking for and the dream of a greener driving world. The comparison was great fun. I admit I'm still more excited about the Plug-in Prius, which is now looking like it will be available starting around spring 2012 in 15 launch states: Arizona, California, Connecticut, Hawaii, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Oregon, Rhode Island, Vermont, Virginia and Washington. Availability is planned to open up to all other states in 2013. Much of the innovation in the development of the Prius appears to be showing up in the 2012 Camry Hybrid

Drought and CO2
August 24, 2011 02:08 PM - Andy Soos, ENN

The large scale project CLIMAITE, led by Risø DTU, has published its first synthesis paper in the journal Global Change Biology, and the conclusion is perhaps a little surprising that the predicted increase in plant growth, due to more CO2 in the atmosphere is noticeably limited when combined with higher temperatures -- and especially summer droughts. "When you've previously seen a significantly higher plant growth at elevated CO2 concentrations, it is typically because it has been controlled studies, where only the CO2 concentration was changed. We fundamentally had the theory that you have to look at the combination of the different climate variables, since the plants in the future will be exposed to multiple changes simultaneously," explains Klaus Steenberg Larsen, who is a researcher in the Biosystems Division at Risø DTU and lead author on the scientific paper.

The Great Virginia Earthquake
August 24, 2011 10:30 AM - Andy Soos, ENN

Nowadays when a disaster strikes the cell phones react. A magnitude 5.8 earthquake struck the National Capital Area on Tuesday, August 23, at 1:51p.m. (EDT), causing moderate shaking and potentially significant damage, and was felt throughout Northern Virginia and neighboring areas. No casualties are expected. Immediately cell phones throughout the area were jammed as everybody called out checking on friends and loved ones as well as what happened. The earthquake occurred near Louisa and Mineral, Va., approximately 100 miles southwest of Washington, DC. It was a shallow earthquake, and shaking was recorded all along the Appalachians, from Georgia to New England. There have been several aftershocks. Such an earthquake is unusual but not unprecedented for the east coast.

Traveling Microbes
August 23, 2011 02:50 PM - Andy Soos, ENN

Microbes live in all parts of the biosphere where there is liquid water, including soil, hot springs, on the ocean floor, high in the atmosphere and deep inside rocks within the Earth's crust. Some recent studies indicate that airborne microbes may play a role in precipitation and weather. Eos, published by the American Geophysical Union, last month reported that bio-aerosols are "leading the high life." In the Eos article, David Smith of the University of Washington and colleagues argue that microbes are “the most successful types of life on Earth” and are the unacknowledged players in many planetary processes, particularly in the atmosphere.

Are Mermaids real? Vampires?
August 23, 2011 12:09 PM - BBC Earth

1. Vampires Tales of vampires which have been the inspiration for horror movies the world over originate from a small flying mammal that weighs less than two ounces. Of the three species of vampire bat the one that has contributed to the misunderstanding and fear of bats more than any other is the infamous common vampire bat. Perhaps an unfair reputation considering that they rarely kill their prey, in fact they can feed without their incision even being noticed due to specially adapted blade like incisors. They are found in the deserts and rainforest of the tropical and subtropical regions of Central and South America, making their homes in caves, mines and tree hollows. If they are unlucky in their night-time search for sustenance for two consecutive nights they will die. Luckily for nursing mothers other bats will regurgitate blood meals to them. So how has this inconspicuous creature become the stuff of nightmares? When explorers returned to Europe from the Americas in the 16th century, news of the bloodsucking creatures augmented the ancient myths of human vampires. Myths which had come about to explain blood dribbling from the mouths of semi-decomposed corpses. These South American night feeders carry and spread the deadly rabies virus and are considered an agricultural pest due to their paralytic affect on cattle herds. While bats may prefer bovine blood they have been known to attack humans. So beware the reality of the vampire myth! 2. Dragons With a reputation reaching back over 1,000 years, the stories that surround this outsized reptile are recalled by cultures all over the world. For instance, in England, St George’s day is celebrated in honour of the man who saved his town - and a princess - by slaying a dragon. As a result of this story, dragons are now considered to be a key part of England's heritage. Portraying one in bold colours across its national flag, Wales makes it clear that dragons are a part of the country's national heritage. It is believed that the ferocious, red dragon that appears on the flag symbolises the strength and courage of the Welsh people. With such an iconic position within the heritage of two cultures, it is not surprising that the dragon is not as mythical as some may think. At three metres long (9.8ft) and weighing around 70kg (150lb), the Komodo dragon is a living, breathing representative of this family of creatures which many think are only found in fairytales. A member of the monitor group, it is the largest living species of lizard. Although populations are now only found on a few volcanic Indonesian islands, fossil evidence suggests that they evolved in Australia and dispersed westward to Indonesia. Whether we celebrate its strength or revel in man's ability to overcome its fearsome spirit, the dragon has burst forth from the story books and is still alive and well in the 21st century.

The Great Upward and Northward Migration is Underway
August 23, 2011 10:36 AM - David A Gabel, ENN

As global temperatures warm, organisms equipped with the gift of mobility and spreading their seed will seek climates with which they are familiar. In the Earth's northern hemisphere, this means traveling both north and to higher elevations. This movement of species has been documented for some time and is expected to continue into the future. However, a new study from the University of York in the United Kingdom has found that plants and animals are responding to the effects of climate change up to three times faster the previously expected.

School Bus Pollution
August 22, 2011 01:25 PM - Andy Soos, ENN

24 million American children ride school buses daily. On average, these students spend an hour and a half each day in a school bus. School buses drive more than 4 billion miles each year. School buses are the safest way for children to get to school. However, pollution from older diesel vehicles have health implications for everyone, especially children. Clean School Bus USA (EPA based) brings together partners from business, education, transportation, and public-health organizations to work toward the goals of reducing the potential health impact on children. School districts, with the help of federal grants (and state grants in some cases) have been working to replace the oldest, most polluting buses, and to upgrade others with better pollution control equipment. (The Diesel Reduction Act was reauthorized for five years in December 2010, but it's unclear how much money Congress will appropriate to continue the program.) The way drivers operate the buses can also have a big impact on the air quality for kids.

Life in a World without Oxygen
August 22, 2011 12:59 PM - Andy Soos, ENN

The Earth’s oldest fossils have been found in Australia by a team from the University of Western Australia and Oxford University. The microscopic fossils show convincing evidence for cells and bacteria living in an oxygen-free world over 3.4 billion years ago. The earliest identified organisms were minute and relatively featureless, and their fossils look like small rods, which are very difficult to tell apart from structures that arise through abiotic physical processes. The oldest undisputed evidence of life on Earth, interpreted as fossilized bacteria, dates to over 3 billion years ago. Other finds in rocks dated to about 3.5 billion years ago have been interpreted as bacteria, with geochemical evidence also seeming to show the presence of life 3,800 million years ago. The new research team, led by Dr David Wacey of the University of Western Australia and including Professor Martin Brasier of Oxford University, report the finding in the journal Nature Geoscience.

Study: A Happy Marriage Can Boost Health and Survivability
August 22, 2011 09:44 AM - David A Gabel, ENN

A very interesting study has recently come out of the University of Rochester, showing that married adults reap increased health benefits than their unmarried counterparts. Women in particular thrive when in a happy marriage. For men, any kind of marriage will do. To prove their theory, researchers observed individuals who underwent coronary bypass surgery. The happily married were over three times more likely to still be alive after 15 years.

The Age of the Moon and the Earth
August 19, 2011 05:02 PM - Andy Soos, ENN

Man lives the traditional 3 score and ten. How old the Moon and Earth? New research using a technique that measures the isotopes of lead and neodymium in lunar crustal rocks shows that the moon and Earth may be millions of years younger than originally thought. The common estimate of the moon's age is as old as 4.5 billion years old (roughly the same age as the solar system) as determined by mineralogy and chemical analysis of moon rocks gathered during the Apollo missions. However, Lawrence Livermore National Laboratory scientist Lars Borg and international collaborators have analyzed three isotopic systems, including the elements lead, samarium and neodymium found in ancient lunar rocks, and determined that the moon could be much younger than originally estimated. In fact, its age may be 4.36 billion years old.
