After decades of public safety campaigns focused on drinking and driving, it may be time to focus on the seventh leading cause of injury-related death, according to Bureau of Occupational Health and Injury Prevention at New York State Department of Health and Columbia University scholars looking at New York State.
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.
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.
The bacteria that sneak past the brain's defenses to cause deadly bacterial meningitis are clever adversaries - they convince their host that they are harmless yet then have freedom to cause disease by taking advantage of a molecular warning signal and inducing the brain's cellular armor to temporarily break down, letting in the bacterial horde.
The blood-brain barrier is a thin network of blood vessels whose cells abut each other very closely, forming protein junctions too tight for bacteria and viruses to fit through. The barrier's purpose is to prevent unwanted material from crossing over from the surrounding bloodstream into brain tissue.
Like with car pool lanes, the rationale for more bicycling infrastructure is that if they are built, more people will use them, and it will save the environment, public health, etc. but like with car pool lanes, the reality turns out to be different. In actual usage 25 percent of highways or more get blocked off for vehicles with multiple occupants while 7 percent of occupants use them, which leads to higher traffic, and the stress and accidents that go with it, and worse emissions due to slower cars.
Men with naturally high levels of the female hormone estrogen have a greater risk of developing breast cancer, according to according to an epidemiology paper published in the Journal of Clinical Oncology.
This is the first time a link between estrogen levels in the blood and male breast cancer has been identified, despite its connection to breast, womb and ovarian cancers in women, according to study author Professor Tim Key, Cancer Research UK's hormone and nutrition expert at the University of Oxford. Men with the highest levels of estrogen were two and a half times more likely to develop breast cancer than men with the lowest levels of the hormone.
A study of 2,377 children with autism, their parents and siblings - data from families with one child with autism and one or more children without the condition - has led to new information on how different types of mutations affect autism risk.
The genetic data was obtained from exome sequencing, which looks at only the protein-coding portions of the genome and came from families participating in the Simons Simplex Collection and from the Simons Foundation Autism Research Initiative, including millions of genetic variants, and has been made freely available to other autism researchers.
A new simulation that explains the collision between clusters of galaxies known as "El Gordo" also challenges popular thinking on the blanket term for undetected 'dark matter'.In general, galaxy clusters grow in size by merging with each other due to gravitations forces despite the expansion of the universe. El Gordo is the biggest known cluster of galaxies, and is in turn the result of the collision between two large clusters. The simulation believes that the collision process compresses the gas within each cluster to very high temperatures so that it is shining in the X-ray region of the spectrum. In the X-ray spectrum this gas cloud is comet shaped with two long tails stretching between the dense cores of the two clusters of galaxies.
Dating apps like Tinder offer a quick look at a potential connection, with a simple swipe to either decline or accept a potential match, so it follows that some people will try to game the system by using an old picture or one that is enhanced using a tool like Photoshop.
So many people do it, at least according to common belief, that is must work. But does it?
People assume some pictures must be fake and they don't want to be "catfished" (slang for a romantic hoax, because less reputable seafood restaurants will serve catfish as something more expensive) so alarm bells ring when something looks too good to be true, or in this case "too hot to trust."
