ACSH - 1 hour 48 min ago

While the recent Pennsylvania decision on surgical consent was about a physician's responsibility it did not consider how it binds physician to patient emotionally. The ritual of consent has many layers to consider.

Spt6: New Gene Expression Mechanism With Possible Role In Cancer

ACSH - Jun 24 2018 - 07:06

Every human cell carries our genome, roughly 3.5 billion letters - DNA - that assemble into our genetic code. RI order for large genomes to fit into the tiny cells, proteins called histones organize and package DNA in cells. DNA wraps around the histones so they can be condensed into the space.

Dinosaurs Couldn’t Stick Out Their Tongues

Science 2.0 - Jun 23 2018 - 23:06
Einstein could stick out his tongue but dinosaurs could not, according to a new paper. Instead of being like modern day lizards or legendary physicists, their tongues were probably rooted to the bottoms of their mouths like alligators. 

The discovery was made by comparing the hyoid bones — the bones that support and ground the tongue — of modern birds and crocodiles with those of their extinct dinosaur relatives. In addition to challenging depictions of dino tongues, the research proposes a connection on the origin of flight and an increase in tongue diversity and mobility.

Polar Ice May Be Softer Than Thought, Which Could Speed Up Sea Level Rise

Science 2.0 - Jun 23 2018 - 22:06
Ice seems solid to the eye, but it is really a material that flows like a viscous liquid. In the polar ice sheets, it flows towards the oceans under its own weight. Knowing how fast the ice flows is of crucial importance to predict future sea level rises, especially if climate change occurs and impacts that.

For a new study, researchers used flow velocities at the surface of the northern Greenland Ice Sheet to create estimates and data from satellite images suggest that the polar ice is softer than scientists believed.

Genetic Heart Mutations Ruled Out As Cause Of Most SIDS Cases

Science 2.0 - Jun 23 2018 - 22:06
Because Sudden Infant Death Syndrome (SIDS), in infants less than a year old, are tragedies without known explanation, scholars have searched for causes beyond stuffed animals in cribs or blaming parents.

SIDS represents up to 80 percent of all sudden unexpected infant deaths with an five in 1,000 live births in the US. The peak incidence occurs between two months and four months of age and is more common in boys. One explanation has been heart disease caused by genetic mutations but a recent study found that is less than 5 percent of cases, much lower than the 20 percent previously estimated.

The Predicament Of Diversity: No One Agrees On What It Means

Science 2.0 - Jun 23 2018 - 15:06

“Diversity” as a concept has a lexical and political value all its own, with a widespread appeal. The problem with that is, however, that no one actually has the same idea of what diversity actually means. There is some consensus that the concept has, over time, morphed into something that it was not originally intended to be. Denise Green’s 2004 study looks at the University of Michigan’s response to a 1997 affirmative action case, and argues that legal precedents such as this one moved the cursor away from social and racial justice towards a narrower, simplified idea about diversity.

A new, large-scale breast cancer study of nearly 760,000 premenopausal women produced a surprising result: as body fat increased, their cancer risk decreased. That's the opposite of the risk for women who have reached menopause. But don't take this to mean it's OK to put on the pounds.

The Smoke and Mirrors of Vaping

Vaping is substance agnostic although the controversy and debate about vaping only involve tobacco or nicotine. The harms of vaporizing depend on what is being vaped. To clear away the smoke, we should be more specific about our concerns.

Social bonding key cause of football violence

Eurekalert - Jun 22 2018 - 00:06
As World Cup fever sets in, increased hooliganism and football related violence are legitimate international concerns. Previous research has linked sports-related hooliganism to 'social maladjustment' e.g. previous episodes of violence or dysfunctional behaviour at home, work or school etc. However, social bonding and a desire to protect and defend other fans may be one of the main motivations not only for football hooliganism, but extremist group behaviour in general, according to new Oxford University research.

New research on avian response to wildfires

Eurekalert - Jun 22 2018 - 00:06
New research explores the effects fire has on ecosystems and the wildlife species that inhabit them. Scientists examined the impacts of fires of different severity levels on birds and how that changes as the time since fire increases. Scientists looked across 10 fires after they burned through forests in the Sierra Nevada. A key finding was that wildfire had strong, but varied, effects on the density of many of the bird species that were studied.

NASA's IMERG examines flooding in southern Texas from tropical disturbance

Eurekalert - Jun 22 2018 - 00:06
While Tropical Storm Bud was lashing parts of western Mexico and causing flooding that extended into the American Southwest, a tropical disturbance was spinning over the Gulf of Mexico and straddling southeastern Texas. This system sat in place for almost a week bringing extremely heavy rainfall and causing a flash flood emergency. More than 15 inches (381 mm) of rain fell in Hidalgo County, Texas between June 18 and 22.

Nathan Schroeder, assistant professor in the Department of Crop Sciences at the University of Illinois, has shown that gonad development varies in other nematodes relative to C. elegans. Specifically, he and graduate student Hung Xuan Bui focused on Steinernema carpocapsae, a nematode used in insect biocontrol applications in lawns and gardens.
