Everyone likes to look at young babies. But who wants to listen? Well...it turns out that other babies do. In fact, a McGill University/UQAM research team has discovered that 6-month-old infants appear to be much more interested in listening to other babies than they are in listening to adults. It is an important finding because the researchers believe that an attraction to infant speech sounds may help to kick start and support the crucial processes involved in learning how to talk.

Infant sounds grab infant attention

Education reform policies that penalize struggling schools for poor standardized test scores may hinder -- not improve -- students' college readiness, if a school's instructional focus becomes improving its test scores, suggests a new study that explored efforts to promote a college-going culture at one Texas high school.

Published recently in The High School Journal, the case study reveals the unintended consequences of school reform policies, and how these mandates may warp schools' instructional focus and thwart students' academic success.

"Cloudy for the morning, turning to clear with scorching heat in the afternoon."

While this might describe a typical late-summer day in many places on Earth, it may also apply to planets outside our solar system, according to a new study by an international team of astrophysicists from the University of Toronto, York University and Queen's University Belfast.

Using sensitive observations from the Kepler space telescope, the researchers have uncovered evidence of daily weather cycles on six extra-solar planets seen to exhibit different phases. Such phase variations occur as different portions of these planets reflect light from their stars, similar to the way our own moon cycles though different phases.

Around a quarter of people experience depression at some point in their lives, two-thirds of whom are women.

Each year more than 11 million working days are lost in the UK to stress, depression or anxiety and there are more than 6,000 suicides. The impact of depression on individuals, families, society and the economy is enormous.

Existing popular alternative energy schemes have an ironic flaw - they make fossil fuels more profitable because they are not predictably consistent, which means expensive contracts for "instant on" traditional providers to prevent blackouts.

The big obstacle in implementing wind energy on a massive scale is the unpredictability of its driving force. Wind comes and goes, frequently shifting speed and direction, and mountainous terrain makes it even more fickle. And yet, customers depending on wind power as their primary source of electricity demand a consistent flow -- not one that dies with the wind. Thus, the success of wind energy depends, in part, on the ability to predict changes in wind flow and adjust the grid accordingly. 

Scientists have discovered a way to regrow bone tissue using the protein signals produced by stem cells, which improves on older therapies by providing a sustainable source for fresh tissue and reducing the risk of tumor formation that can arise with stem cell transplants.

The authors of the new study say they are the first to extract the necessary bone-producing growth factors from stem cells and to show that these proteins are sufficient to create new bone. The stem cell-based approach was as effective as the current standard treatment in terms of the amount of bone created and could help treat victims who have experienced major trauma to a limb, like soldiers wounded in combat or casualties of a natural disaster. 

A recent study concluded that low-income and uninsured women in states that are not expanding their Affordable Care Act (ACA) Medicaid coverage are less likely to receive breast and cervical cancer screenings compared to states that are implementing expansions, even though such low income people are now given health care coverage under the ACA.

Transposable elements are DNA sequences that are capable of changing their genome position by cut and paste or copy and paste through the enzyme transposase.

This ability can be harmful for hosts if transposable elements destroy functioning genes, but it can also bring advantages. From an evolutionary point of view, transposable elements diversify the genome and open up chances for adaptation.

Not only that the Theory of Everything cannot be reached by empirical science. Experiment cannot even decide which medium level theory is correct and who was supposedly wrong.

There are those who believed that B.B. King wasn’t the world’s greatest guitar player, including the man himself. In a recent interview he said:

I call myself a blues singer, but you ain’t never heard me call myself a blues guitar man. Well, that’s because there’s been so many can do it better'n I can, play the blues better'n me.

And his musical vocabulary was limited. King once told Bono: “I’m no good with chords, so what we do is, uh, get somebody else to play chords… I’m horrible with chords”. He even claimed that he couldn’t play and sing at the same time.
