I've talked before about how life on present day Mars could be vulnerable to Earth life. If only humans could be sterilized of other life, like a plant seed. But sadly, we can't do that, and it would kill us to try. Recent ideas, and experiments in Mars simulation chambers suggest that there may be liquid water habitats on the surface of Mars. They may be no more than droplets of water a few millimeters in diameter, but these still are, as Nilton Renno said, "Swimming pools for a microbe".

Unless you are a wealthy elite, an electric car is not a viable option because gasoline still rules when it comes to energy density, meaning electric has a more limited range, and solar energy is not close to replacing fossil fuels yet so the environment is not winning.

Archaeologists have found evidence of an ancient gold trade route between the south-west of the UK and Ireland, which would mean people were trading gold between the two countries as far back as the early Bronze Age, 2500 B.C.

The finding was made after measuring the chemical composition of early gold artifacts in Ireland and discovering that the objects were actually made from imported gold, rather than Irish. The gold is most likely to have come from Cornwall, which means the symbiotic link between Ireland and England is even farther back then believed.

Physics at the UAB have found the “formula” to construct a quantum thermometer with enough precision to detect minute fluctuations in temperature in regions as small as the inside of a cell. The research appears today in the journal Physical Review Letters.

Researchers from the UAB and the University of Nottingham, in an article published today in Physical Review Letters, have fixed the limits of thermometry, i.e., they have established the smallest possible fluctuation in temperature which can be measured. The researchers have studied the sensitivity of thermometers created with a handful of atoms, small enough to be capable of showing typical quantum-style behaviours.

An advisory committee to the Food and Drug Administration (FDA) has recommended the approval of the drug, flibanserin, for premenopausal women who are distressed by a lack of sexual desire. The little pink pill has been hailed as “Viagra for women”.

In the animal kingdom, predators use a full range of strategies, such as camouflage, speed and optical illusions, to catch their prey. Meanwhile, prey species resort to the same tactics to escape from their predators. Such tricks are also used at the molecular level, as discovered by researchers from the CNRS, INRA, CEA and INSERM in one of the most devastating bacterial plant pathogens in the world, which bypasses plant cell defenses by preventing an immune signaling from being triggered.

Even more surprising is the fact that plant cells have developed a receptor incorporating a decoy intended to catch the invader in its own trap. 

Every year, typhoons over the western North Pacific – the equivalent to hurricanes in the North Atlantic – cause considerable damage in East and Southeast Asia.

Super Typhoon Haiyan of 2013, one of the strongest ocean storms ever recorded, devastated large portions of the Philippines and killed at least 6,300 people. It set records for the strongest storm at landfall and for the highest sustained wind speed over one minute, hitting 315 kilometers (194 miles) per hour when it reached the province of Eastern Samar.

In recent years, the biopharmaceutical industry has seen an explosion in the availability of Big Data that can generate valuable insights. Despite this, the inherent costs and challenges that come with utilizing Big Data have caused the biopharmaceutical sector to embrace Big Data analytics much slower than other industries.

According to a recent study by benchmarking firm, Best Practices, LLC, 53% of participants already have a Big Data team or function in place; however, these organizations are still in the early stages of utilizing large data sets from different sources to inform critical aspects of Medical Affairs operations.

The light we receive from the sun is composed of all visible frequencies, among others, and it therefore appears white to our natural detection system - the human eye. Apparently, evolution caused us to develop a vision which works best at the center of the frequency spectrum emitted by the Sun. 

That notwithstanding, I am sure that if you ask the question "what colour is the Sun" to the average Joe, you will get an equal share of "white" and "yellow", and maybe some "red" answers. Besides, who among us has never painted a red Sun in a blue sky as a child ? 

When a space hurricane was unleashed from the sun on January 7 2014, space-weather centers around the world sent out warnings.

The hurricane was heading directly for Earth and was predicted to produce a strong geomagnetic storm. But then an unexpected thing happened: the storm bypassed Earth and headed for Mars instead.
