Study Finds Breastfeeding Leads to Good Behavior in Childhood
May 13, 2011 09:34 AM - David A Gabel, ENN

Breastfeeding, the act of feeding an infant directly from the human breast, is known to be good for children. There are formulas available which can simulate a mother's milk, but can never perfectly replicate the natural act of breastfeeding. In the past, studies have shown inconsistent results as to whether or not breastfeeding really improves childhood wellbeing in areas such as IQ, behavior, and obesity. However, a new study from the University of Oxford has put a firmer grip on this already well-known theory.

Barred Owls
May 12, 2011 02:44 PM - Andy Soos, ENN

The Barred Owl is a large typical owl. It goes by many other names, including eight hooter, rain owl, wood owl, and striped owl, but is probably known best as the hoot owl. Barred owls may be more abundant in coniferous forests of the Pacific Northwest than previously recognized, according to research published today in the Journal of Wildlife Management. This finding likely has implications for the recovery of the federally threatened northern spotted owl. Related studies about the competitive interactions between barred owls and spotted owls are under way, with results anticipated this summer.The research published today also emphasizes the need for species-specific survey methods to document and understand the interactions between the northern spotted owl and its close relative, the barred owl. Barred owls, which have gradually expanded their range into the Pacific Northwest over the past 30 years, are now thought to be competing with dwindling numbers of spotted owls for critical resources such as food and nesting habitat.

Put up your data and step away from the car
May 11, 2011 03:31 PM - Kathleen Neil, Contributiing Editor,ENN

Your driving and charging habits mean a great deal to companies selling Electric Vehicles (EV), to government when developing policy, to firms developing wireless communications or charging stations and to utility companies that will be required to supply the electricity. All of them want to know when/where and how much electricity is needed and how it is obtained as more and more people buy EV. Most likely your decision to buy an EV might depend on how far you will be driving regularly. BEV gives more range, but HPEV save you from range anxiety. Either way, you are only going to spend the extra money to own an EV if you know you can drive/charge the way you want. Whether we like it or not, that means it is as important to us as it is to utilities, car companies or the government that good vehicle charging data become available. Americans have always been leery of intrusions into their privacy. Use data from personal electric vehicles, be they BEV or PHEV, will become only more important to the development of policy and marketing for greener driving goals. Think about your EV. You leave home one morning after having charged it up overnight. You go to work, where your employer provides a parking bay with an EV charger and charge it again. This charge will be what you need to get home, but what happens when your daughter calls and asks you to pick up your grandchild from daycare for her? Well, that's across town and you need extra battery range for that. But, you check your iPhone app and see that Walgreens has installed chargers at the store near daycare, so you figure you'll pick up your granddaughter and the two of you can get her the stuffed animal you promised her while the car charges again. Any other day maybe you’d only charge at home and work.

How Old Neanderthal Man?
May 11, 2011 07:58 AM - Andy Soos, ENN

The Neanderthal is an extinct member of the Homo genus known from Pleistocene specimens found in Europe and parts of western and central Asia. The first proto-Neanderthal traits appeared in Europe as early as 350,000—600,000 years ago. These characteristics are generally thought of as disappeared in Asia by 50,000 years ago and in Europe by about 30,000 years ago. Researchers have dated a Neanderthal fossil discovered in a significant cave site in Russia in the northern Caucasus, and found it to be 10,000 years older than previous research had suggested. This new evidence throws into doubt the theory that Neanderthals and modern humans interacted for thousands of years. Instead, the researchers believe any co-existence between Neanderthals and modern humans is likely to have been much more restricted, perhaps a few hundred years. It could even mean that in some areas Neanderthals had become extinct before anatomically modern humans moved out of Africa.

El Nino Tree Ring Story
May 10, 2011 07:27 AM - Andy Soos, ENN

El Niño and its partner La Niña, the warm and cold phases in the eastern half of the tropical Pacific, play havoc with climate worldwide. Predicting El Niño events more than several months ahead is now routine, but predicting how it will change in a warming world has been hampered by the short historical record. El Niño/La Niña-Southern Oscillation is a quasiperiodic climate pattern that occurs across the tropical Pacific Ocean roughly every five years. It is characterized by variations in the temperature of the surface of the tropical eastern Pacific Ocean—warming or cooling known as El Niño and La Niña respectively—and air surface pressure in the tropical western Pacific—the Southern Oscillation. record. An international team of climate scientists from the University of Hawaii at Mānoa recently found that annually resolved tree-ring records from North America, particularly from the U.S. Southwest, give a continuous representation of the intensity of El Niño events over the past 1,100 years and can be used to improve El Niño predictions.

Andean Earthquakes to the East
May 9, 2011 07:42 AM - Andy Soos, ENN

The region west of the Andes Mountains is the leading edge of the South American continent into the Pacific Ocean. Subduction of the Nazca plate beneath South America has driven the growth of the Andes Mountains. Subduction has routinely generated earthquakes larger than magnitude 8.0 along the western margin of the mountain belt. Lesser known for tectonic activity is the eastern side. The region east of the central Andes Mountains has the potential for larger scale earthquakes than previously expected, according to a new study posted online in the May 8th edition of Nature Geoscience. Previous research had set the maximum expected earthquake size to be magnitude 7.5 (Richter), based on the relatively quiet history of seismicity in that area. This new study by researchers from the University of Hawaii at Manoa and colleagues contradicts that limit and instead suggests that the region could see quakes with magnitudes 8.7 to 8.9.

Seawater Bucket
May 6, 2011 01:25 PM - Andy Soos, ENN

Life is incredibly complex. It is wrong to assume that what you can easily see is all there is. There is a plethora of microscopic life. From a bucket of seawater, scientists have unlocked information that may lead to a deeper understanding of organisms as different as coral reefs and human disease. By analyzing genomes of a tiny, single-celled marine animal, they have demonstrated a possible way to address diverse questions such as how diseased cells differ from neighboring healthy cells and what it is about some Antarctic algae that allows them to live in warming waters while other algae die out. Debashish Bhattacharya, professor of ecology, evolution and natural resources in Rutgers’ School of Environmental and Biological Sciences, and others of the Bigelow Laboratory of Ocean Sciences, have published their results in the journal Science. They used sophisticated new technologies to sequence the genomes of individual picobilophytes, tiny microbes first discovered in 2007. At less than 10 micrometers across, they are some of the tiniest marine animals known to science.

What makes humans special? The Power of communication. New from BBC Earth
May 6, 2011 10:10 AM - Editor, BBC Earth

A human's need to communicate, can be observed from the first moments of life. The intuitive reaction of a newborn to cry, lays the stepping-stone for a process which at its heart, will enable every human to successfully communicate their experience of being alive. It has been said that words are man's greatest achievement. With the first utterances of symbolic language emerging 2.5 million years ago, slowly evolved by the first Homo sapiens — the solid foundations of modern articulation have decidedly been set. Yet many would argue that speech and language was developed not out of want, but out of need. Therefore in what ways do humans communicate”without using words? Music has long been a way of communicating for necessity as well as pleasure. Such as the use of a lullaby to sooth, a folk song to warn and a chant to call to arms! But in what ways do we use rhythm and melody to communicate with nature itself?

Comet Elenin
May 5, 2011 01:57 PM - Andy Soos, ENN

A comet is an icy small Solar System body that, when close enough to the Sun, displays a visible coma (a thin, fuzzy, temporary atmosphere) and sometimes also a tail. These phenomena are both due to the effects of solar radiation and the solar wind upon the nucleus of the comet. Comet nuclei are themselves loose collections of ice, dust, and small rocky particles, ranging from a few hundred meters to tens of kilometers across. Comet Elenin is coming to the inner-solar system this fall of 2011. Comet Elenin (also known by its astronomical name C/2010 X1), was first detected on Dec. 10, 2010 by Leonid Elenin, an observer in Lyubertsy, Russia, who made the discovery using the ISON-NM observatory near Mayhill, New Mexico. At the time of the discovery, the comet was about 647 million kilometers (401 million miles) from Earth. Over the past four-and-a-half months, the comet has — as comets do — closed the distance to Earth's vicinity as it makes its way closer to perihelion (its closest point to the sun). As of May 4, Elenin's distance is about 170 million miles. It is scheduled to come as close as 22 million miles.

Study Finds Sea-Level Rise Likely on West Coast
May 5, 2011 09:20 AM - David A Gabel, ENN

For the last few decades, sea levels of the eastern North Pacific Ocean along the west coast of North America have remained remarkably steady as other sea levels rise around the world. That is due to the dominance of cold surface waters along the coast. According to a new study from the University of California (UC) San Diego, the cold waters on the coast will give way to warmer waters beginning this decade, which will lead to accelerated sea-level rise. The change in water temperature is related to the climate phenomenon in the Pacific Ocean known as the Pacific Decadal Oscillation (PDO).
