Face morphing has become quite popular in the last years; from mixing the faces of two celebrities to guessing how your baby could look, many TV shows and apps use software which changes one face into another through a continuous and smooth transition. Among the different mathematical tools that can be used for face morphing […]
The most used mechanism to guarantee universal education in a country is by providing free public education, where public means both publicly financing and public provision. Milton Friedman (1962) made the case to keep the public funding but make the provision private through a system of school vouchers. Say that the State spends 100 per […]
2,000-year-old life-size carvings of camels found in Saudi Arabia Life-size stone carvings of camels dating back about 2,000 years have been found in Saudi Arabia. The 12 or so carvings are stylistically different from others found on the Arabian Peninsula and are offering researchers clues as to how rock art developed in the region. The […]
Modern organic industrial chemistry started when William Henry Perkin serendipitously synthesized mauveine in 1856 while he was attempting the total synthesis of quinine. Since then, thousands of new organic products have been created in the laboratory for industrial purposes. Among them, in 1913, an orange-red pigment was found, first known as Vat Orange 3 dye […]
Sometimes, scientists give very good news, and in 2017 we have had one of these occasions. Boys suffering from X-linked adrenoleukodystrophy (X-ALD), a devastating neurodegenerative disease, have been cured with gene therapy. The STARBEAM study was performed by an international team headed by David A. Williams from the Boston Children’s Hospital in Massachusetts (USA), and […]
«BPA-Free», «No Bisphenol A» and similar labels have become a sort of seal of quality for those products where they are on display, especially containers and baby products. But, what is bisphenol A? In 1936 bisphenol A (BPA) was identified as a synthetic estrogen, this is, an artificial compound that shows estrogen-mimicking action. Estrogens are […]
Some mental health conditions share genetic patterns A study of brain tissue from people with either schizophrenia, bipolar disorder, autism, depression or alcoholism suggests there are some similar gene expression patterns among those conditions. New Scientist Musk’s Tesla Roadster plots new orbital course The new projected orbit of SpaceX founder Elon Musk’s Tesla Roadster, launched […]
What only a decades ago seemed impossible for chemists, determining the chemical structure of molecules directly from experimental images, is now routinely done. Not only that, the information about bond order, intermediates, and products of on-surface chemical reactions or charge distribution within molecules can also be quantified from those images. Two main techniques have made […]
During 2017 we have been witnessing the first tests of what might be called an integral hyperloop system at the Virgin Hyperloop One installations in Las Vegas, Nevada. Virgin Hyperloop One — named Hyperloop One before Virgin Group’s entry into its shareholder structure — leads, by its own merits, the pack of companies pursuing the […]
Vitamin D is an atypical vitamin because it is not a real vitamin. Vitamins are supposed to be essential, meaning that our organism cannot live without them but their synthesis cannot take place in our cells, so we must ensure an external intake through the diet. However, only 10% of vitamin D daily requirements come […]
