Colleges and universities are struggling to stay afloat.

The reasons are numerous: declining numbers of college-age students in much of the country, rising tuition at public institutions as state funding shrinks, and a growing skepticism about the value of a college degree.

More than 60% of traffic collisions at intersections involve left turns. Some U.S. cities – including San Francisco, Salt Lake City and Birmingham, Alabama – are restricting left turns.

Dr. Vikash Gayah, a professor of civil engineering at Penn State University and the interim director of the Larson Transportation Institute, discusses how left turns at intersections cause accidents, make traffic worse and use more gas.

How dangerous are left turns at intersections?

People dedicated to the art of grilling often choose lump charcoal – actual pieces of wood that have been turned into charcoal – over briquettes, which are compressed charcoal dust with other ingredients to keep the dust together and help it burn better.

The kinds of wood used to make lump charcoal affect how it burns and how the food tastes when grilled. Dedicated grillers are often willing to pay a premium for higher heat, no additives, particular flavors and the cleaner burn they get from particular wood species in lump charcoal.

Buyers probably expect the label to accurately report how much charcoal they are getting, what kind of wood it is, and where the wood was grown.

Former Natural Resources Defense Council Attorney Robert F. Kennedy, Jr. didn't get more pro-science by becoming Secretary of Health and Human Services, he instead acts like his beliefs in The Ancient Ways - no cell phones, no vaccines, food scarcity - have been validated.

He has proposed "wellness farms" to combat various problems he insists are lifestyle issues only government can fix. Basically, he is piling onto beliefs he advocated when his friend and fellow Democrat President Barack Obama was in office.(1) By his second term, President Obama wanted government so desperately in the lives of people he manufactured two things that "Obamacare" could fix; a prediabetes and a vaping epidemic.

The U.S. Department of Energy’s decision to claw back US$3.7 billion in grants from industrial demonstration projects may create an unexpected opening for American manufacturing.

Scholars have developed a method to encode binary and Morse code messages in ice.

A 'message in a bubble' has limited practical utility, information storage in Antarctica and the Arctic is expensive but less challenging than storing message in ice, but they are more covert than paper documents and can easily be carried.

In the Cradles of Civilization, there are entire cities covered in sand that were once thriving places. The climate shifted and humans did with it. One of our greatest cultural achievements has been our ability to adapt to a natural world that is out to destroy and rebuild everything, including us.

A new study shows we were adapting to diverse areas and environmental changes long before the creation of agriculture and resulting civilizations. Even before worldwide migration, we were bending African forests and deserts. Failing to do so was why the probably earliest migration efforts seemed to have disappeared with barely a trace. 

Screen time is a concern for parents and mental health advocates but looking at screen time may be treating the symptom rather than the disease. What is a true harbinger for risk of mental health problems is addictive behavior in young people.

National surveys have documented rising screen use but a new paper mapped longitudinal trajectories of addictive use specifically, rather generic limits on screen time.The data were social media use of nearly 4,300 children enrolled in the Adolescent Brain Cognitive Development Study, starting at age 8, and how use changed over the next four years.
