A new control suite with a microprocessor, wireless radio, GPS receiver, and an attitude and heading reference system gives lazy dog owners  a way to command their pets with a remote control, or a smart phone, or even with out hands at all - the new system provides autonomous guidance of the canine using an embedded command module with vibration and tone generation capabilities. Tests in a structure and non-structured environment show obedience accuracy up to almost 98%.

That old "best friend" can get a bit tiresome, all that rolling over, shaking paws, long walks and eating every crumb of food off the floor. But, what if there were a way to command your dog with a remote control, or even via your smart phone...or even without hands?

A new species called Gondwanascorpio emzantsiensis is now the oldest known land-living animal discovered in Gondwana. Dr. Robert Gess, from the Evolutionary Studies Institute at Wits University, discovered the 350 million year old fossilized scorpion from rocks of the Devonian Witteberg Group near Grahamstown.

Explaining his discovery, Gess said that early life was confined to the sea and the process of terrestrialization - the movement of life onto land - began during the Silurian Period roughly 420 million years ago. The first wave of life to move out from water onto land consisted of plants, which gradually increased in size and complexity throughout the Devonian Period. 

Syphilis has become a serious health issue (again) in Latin American countries, with 3 million cases. Every year 330,000 pregnant women with syphilis receive no treatment, resulting in 110,000 children born with congenital syphilis and a similar number of miscarriages.

Commercial kits for early syphilis detection are too expensive to use in a systematic screening of all pregnancies in Latin American countries where, in some areas, there are five new cases daily. The proteins needed for the test come from the bacterium that causes syphilis. And reducing the price of the tests requires producing high volumes of these proteins.  

Clouds, which can absorb or reflect incoming radiation and affect the amount of radiation escaping from Earth's atmosphere, remain the greatest source of uncertainty in global climate modeling.

ine making (and drinking) has long been more art than science, a subjective experience. But that is changing. In the future, you will be able to find a type of wine you like and have it consistently - all determined by science.

Unlocking the chemical processes that create a wine's aroma is the objective of scientists who recently sequenced the genome of the high-value Tannat grape, from which "the most healthy of red wines" are fermented. 

Tannat is the "national grape" of Uruguay, South America's 4th-largest wine producer with 21,000 acres of vineyards. More than a third of the grapes grown are Tannat, from which the country's signature wines are produced. 

Technology may not seem like more of a woman's world than science, but in some ways it is - Ada Lovelace is revered by computer programmers and is well-known in popular culture, while Laura Bassi, the first women to forge a professional scientific career, is basically unknown outside physics.

Laura Bassi was born in Bologna in 1711 and rose to celebrity status across the globe, gaining a reputation as being the best physics teacher of her generation and helping to develop the discipline of experimental physics.She was the "woman who understood Newton", even more of a fascination then because so few men in science understood Newton.
