The belief by Western elites that ancient people lived in some sort of harmony with the land, a belief popular for the last century, has been punctured again.

Hubble Space Telescope astronomers are finding that the old adage "what goes up must come down" even applies to an immense cloud of hydrogen gas outside our Milky Way galaxy. The invisible cloud is plummeting toward our galaxy at nearly 700,000 miles per hour.

Though hundreds of enormous, high-velocity gas clouds whiz around the outskirts of our galaxy, this so-called "Smith Cloud" is unique because its trajectory is well known. New Hubble observations suggest it was launched from the outer regions of the galactic disk, around 70 million years ago. The cloud was discovered in the early 1960s by doctoral astronomy student Gail Smith, who detected the radio waves emitted by its hydrogen.

WASHINGTON, D.C. -- When countries, rich or poor, support breastfeeding through meaningful investments and programs, it has an impact on their bottom line and the health of women and children. The Lancet Breastfeeding Series, released today, finds that globally, the costs of lower cognitive ability associated with not breastfeeding amount to more than $300 billion each year, a figure comparable to the entire global pharmaceutical market. About 820,000 child deaths could be prevented annually (about 13 percent of all under-5 child deaths) by improving breastfeeding rates, in addition to the lives already saved by current breastfeeding practices.

A ground-breaking study has confirmed the long held assumption that camouflage protects animals from the clutches of predators, and offers insights into the most important aspects of camouflage.

The research, by scientists from the Universities of Exeter and Cambridge, investigated the camouflage of ground-nesting birds in Zambia, using sophisticated digital imaging to demonstrate how they would appear from the perspective of a predator.

The team found that animals or eggs that matched the pattern or contrast of the surrounding landscape were less likely to be eaten by their natural predators.

The study is published in leading journal Scientific Reports on Friday, January 29 2016.

Research at King's College London has revealed subtle brain differences in adult males with autism spectrum disorder (ASD), which may go some way towards explaining why symptoms persist into adulthood in some people with the disorder.

ASD affects around 1 in 100 people in the UK and involves a spectrum of conditions which manifest themselves differently in different people. People with ASD can have varying levels of impairment across three common areas, which might include: deficits in social interactions and reciprocal understanding, repetitive behaviour and narrow interests, and impairment in language and communication.

Detecting molecular alterations in early breast cancer development is key in the development of more effective cancer prevention and early detection strategies. New research funded by The Eve Appeal and the European Union's Seventh Framework Programme, published today in science journal Nature Communications shows clear evidence that DNA changes are already present in the healthy tissue from women with breast cancer.

As someone who is keen on astronomy, I am of course keen on the Thirty Meter telescope myself. And I've heard those arguments of the astronomers, about how it is an ideal site for astronomy, about the value of the astronomy that can be done with this telescope and so on. But I've also heard the other side too.

There are many telescopes on the summit already, so it's not like they are saying not to build telescopes at all up there.

SIZE OF THE PROPOSED TELESCOPE

What you might not realize at first is quite how huge it is - it's difficult to get a sense of scale from the images:

It's higher than the Niagara falls.

WORCESTER, MA - A study published in the journal Science found that activation in pregnant mice of a particular immune response, similar to what may occur with certain viral infections during pregnancy, alters the brain structure of the mouse offspring and causes behavioral changes, reminiscent of those observed in humans with autism spectrum disorder (ASD).

Several past human studies have suggested a correlative link between maternal viral infection during pregnancy and risk of autism spectrum disorder. Mouse models have been created and used to study how maternal immune activation influences autism-like behavior, but the mechanism underlying this was not known until now.

When you don't have much money, you have to prioritize, and that is a key issue that the wealthy elites who set off on insurance reform forgot to factor in. Massachusetts, which the Federal government claimed was a model for its Affordable Care Act, now has to spend 40 percent of its budget so that 25 percent of people can have even basic health care. That is not sustainable.

What is a great way to ensure that conservation has no support at all from the public? Hand nature over to centralized bureaucrats and create environmental groups full of lawyers to sue to make sure people are treated as the enemy.

Or just have centralized government tell people what to do, as in the communist dictatorship China.

Yet there is a better way. Communists love cold, hard cash just like capitalists, and conservation programs that compensate citizens for changing habitat-damaging behavior really work, according to results of a program in China that aims to restore forests and habitat for the endangered giant panda.
