Traditional Medicine: Environment change threatens indigenous know-how Posted: 13 Feb 2014 07:35 AM PST Traditional medicine provides health care for more than half the world's population, but no one has really looked at how the environment affects traditional medicine. Studying 12 ethnic groups from Nepal biologists found that plant availability in the local environment has a stronger influence on the make-up of a culture's medicinal floras. This means that the environment plays a huge role in shaping traditional knowledge. This is very important, especially when you think of the risks that these cultures are already facing.

Marriage's 'haves' and 'have nots' Posted: 13 Feb 2014 07:35 AM PST Today Americans are looking to their marriages to fulfill different goals than in the past -- and although the fulfillment of these goals requires especially large investments of time and energy in the marital relationship, on average Americans are actually making smaller investments in their marital relationship than in the past, according to new research.

Missing monsoon lead to 'years without a summer' Posted: 13 Feb 2014 07:34 AM PST Why do cold, rainy summers in Europe follow intense volcanic eruptions in the tropics? A research team may have found the answer: volcanic emissions in the atmosphere block sunlight and can thereby affect the amount of precipitation in other parts of the world.

We will fight them with mosquitoes: Historical evidence of biological weapons research in Nazi Germany Posted: 13 Feb 2014 06:51 AM PST Scientist finds historical evidence of biological weapons research in Nazi Germany. Researchers came to the conclusion that, although a major entomological institute was established to combat insect-borne diseases such as typhoid, it also carried out research into whether mosquitoes -- which host malaria -- could be used in biological warfare.

Why did the orangutan come down from the trees? Posted: 13 Feb 2014 06:51 AM PST Orangutans come down from the trees and spend more time on the ground than previously realized -- but this behavior may be partly influenced by humans, a new study has found.

Fossil teeth shows that environment, as well as diet, may impact dental wear Posted: 13 Feb 2014 06:50 AM PST Researchers have established that pits and scratches on the teeth of mammal fossils give important clues to the diet of creatures that lived millions of years ago. A new study of dental microwear on shrews suggests that environment may impact teeth, as well.

Love is good for the heart, cardiologist says Posted: 13 Feb 2014 06:50 AM PST With Valentine's Day just one day away, a cardiologist says being involved in a healthy, loving relationship is good for the heart.

Reindeer counteract certain effects of climate change Posted: 13 Feb 2014 05:40 AM PST One of the consequences of a warmer climate can be that lowland and southern plants migrate higher up in the mountains. Ecologists now show that reindeer, voles and hare can prevent these invasions.

Drastic chemical change occurring in birth of planetary system: Has the solar system also experienced it? Posted: 13 Feb 2014 05:37 AM PST A new star is formed by gravitational contraction of an interstellar molecular cloud consisting of gas and dust. In the course of this process, a gas disk (protoplanetary disk), whose size is on the order of 100 AU, forms around the protostar and evolves into a planetary system. The Solar System was also formed in this way about 4.6 billion years ago, and life was eventually born on the Earth. How unique in the Universe is the situation which happened for the Solar System? In order to answer this question, understanding the formation of protoplanetary disks as well as the associated chemical evolution in various star forming regions is essential.

Geophysicist teams with mathematicians to describe how river rocks round Posted: 12 Feb 2014 03:37 PM PST For centuries, geologists have recognized that the rocks that line riverbeds tend to be smaller and rounder further downstream. But these experts have not agreed on the reason these patterns exist. Abrasion causes rocks to grind down and become rounder as they are transported down the river. Does this grinding reduce the size of rocks significantly, or is it that smaller rocks are simply more easily transported downstream? A new study has arrived at a resolution to this puzzle.

Ancient settlements and modern cities follow same rules of development Posted: 12 Feb 2014 03:37 PM PST Recently derived equations that describe development patterns in modern urban areas appear to work equally well to describe ancient cities settled thousands of years ago, according to a new study.

Whales viewed from space: Satellite technology can be used to count whales Posted: 12 Feb 2014 03:37 PM PST Scientists have demonstrated how new satellite technology can be used to count whales, and ultimately estimate their population size. Using Very High Resolution satellite imagery, alongside image processing software, they were able to automatically detect and count whales breeding in part of the Golfo Nuevo, Peninsula Valdes in Argentina.

Ancient reptile birth preserved in fossil: Ichthyosaur fossil may show oldest live reptilian birth Posted: 12 Feb 2014 03:37 PM PST Ichthyosaurs were giant marine reptiles that evolved from land reptiles and moved to the water. Scientists report a new fossil specimen that belongs to Chaohusaurus (Reptilia, Ichthyopterygia), the oldest of Mesozoic marine reptiles that lived approximately 248 million years ago. The partial skeleton was recovered in China and may show a live birth.

Winning at darts: Timing of dart release or hand position may improve dart throwing accuracy Posted: 12 Feb 2014 03:36 PM PST Two major strategies are attributed to accurate throwing: timing the object release, and the using hand positioning at release to compensate for releasing the object at variable times. To better understand these strategies, researchers investigated whether expert dart players utilize hand movement that can compensate for the variability in their release timing.

Mathematical beauty activates same brain region as great art or music Posted: 12 Feb 2014 03:35 PM PST People who appreciate the beauty of mathematics activate the same part of their brain when they look at aesthetically pleasing formula as others do when appreciating art or music, suggesting that there is a neurobiological basis to beauty.
