Ancient records tell us that the intrepid Viking seafarers who discovered Iceland, Greenland and eventually North America navigated using landmarks, birds and whales, and little else. There’s little doubt that Viking sailors would also have used the positions of stars at night and the sun during the daytime, and archaeologists have discovered what appears to be a kind of Viking navigational sundial.

Analysis of ancient Babylonian tablets reveals that, to calculate the position of Jupiter, the tablets' makers used geometry, a technique scientists previously believed humans had not developed until at least 1,400 years later, in 14th century Europe. These tablets are the earliest known examples of using geometry to calculate positions in time-space and suggest that ancient Babylonian astronomers may have influenced the emergence of such techniques in Western science. In this Report, Mathieu Ossendrijver discusses the translation of four almost completely intact tablets that were most likely written in Babylon between 350 and 50 BCE. They depict two intervals from when Jupiter first appears along the horizon, calculating the planet's position at 60 and 120 days.

Fat is back, at least in some sense. It has just been replaced with polyunsaturated fats in the minds of nutritionists. 

Studies on low-fat, high-carbohydrate diets and the recently popular fad called the Mediterranean diet have shown similar results in weight loss but are mixed when it comes to cholesterol, mostly because nutritional epidemiology relies on people remembering what they ate. To try and augment those, studies are done with animals, and they can provide some guidance but are often misused (what food hasn't been found to be a carcinogen in rats by now?). Still, that is what we have and they can at least provide some guidance on what works best for improved health. Then studies can be done with people.

A new simple nanowire manufacturing technique uses self-catalytic growth process assisted by thermal decomposition of natural gas. According to the research team, this method is simple, reproducible, size-controllable, and cost-effective in that lithium-ion batteries could also benefit from it.

In their approach, they discovered that germanium nanowires are grown by the reduction of germanium oxide particles and subsequent self-catalytic growth during the thermal decomposition of natural gas, and simultaneously, carbon sheath layers are uniformly coated on the nanowire surface. 

BUFFALO, N.Y. - Health care systems and providers need to understand the unique realities of military culture in order to work effectively with veterans and military families, according to the findings of a study by a University at Buffalo research team.

Results of the paper published in the journal Military Behavioral Health suggest that health care and mental health care providers and staff should receive training that provides them with enough knowledge to understand the military's culture and values and how that belief system also affects the veterans' transition from a service member identity to a civilian identity.

Why do people on the left think American media is right wing? Because journalists are paid by corporations funded by other corporations? Why do people on the left think journalism is right wing? Because journalists go into the field to make a difference rather than to talk about news or events or science, and when people want to be important, they become activists.

And controlling media works.

While many groups find media bias to be a negative, social psychologists say it can be a benefit; by getting them to produce positive content or conciliatory messages about ethnic groups and genders. 

Improving Perceptions

January 29, 2016 - For women undergoing breast cancer surgery, a technique called lipofilling--using the patient's own fat cells to optimize the results of breast reconstruction--does not increase the risk of recurrent breast cancer, reports a study in the February issue of Plastic and Reconstructive Surgery®, the official medical journal of the American Society of Plastic Surgeons (ASPS).

An international team of biologists has discovered how specialized enzymes remodel the extremely condensed genetic material in the nucleus of cells in order to control which genes can be used. The discovery will be published in the print edition of the journal Nature on Feb. 4, 2016.

When the moon is high in the sky, it creates bulges in the planet's atmosphere that creates imperceptible changes in the amount of rain that falls below.

New University of Washington research to be published in Geophysical Research Letters shows that the lunar forces affect the amount of rain - though very slightly.

January 29, 2016 - Two things people always need in life: food and love. According to psychologists, understanding the forces that drive both our hunger and our desire could help us eat healthier and have more satisfying relationships.

First Impressions: Photo, video, or in-person?

Just as supermarkets offer plenty of choices, modern dating, from online sites to speed dating, greatly increases the ability to search for and meet potential mates. Lucy Hunt, Ph.D. candidate from the University of Texas - Austin, wanted to understand if the medium in which someone introduces their self affects another person's perception. She discovered when it comes to first impressions, a picture is not worth a thousand words.
