DNA - inheritance - is more important than the color of your eyes or your hair, it can also influence whether you might develop certain diseases, like cystic fibrosis or hemophilia. Evolution - survival of the fittest - may seem like the great biological equalizer but mankind has clearly conquered it, since all kinds of people who might have died in the past due to foodborne diseases or tainted water or diseases no longer do.
A National Academy of Sciences panel said that, with proper governance and other safeguards, we should commence more research on geoengineering — technologies that might let humanity deliberately intervene in nature to counter climate change. With the planet facing potentially severe impacts from global warming in coming decades, drastically reducing emissions of carbon dioxide and other greenhouse gases was by far the best way to mitigate the effects of a wa
When "The Daily Show" with Jon Stewart announced he was leaving the program, corporate journalism declared that Millennials without faux news would have no news at all. In reality, Millennials barely watched it, the steady viewers were older and wanted to seem like Millennials, but journalists couldn't figure out where else they might be getting news. Unless they were just passive and uninterested in civic issues - newsless.
When most people think of cosmic rings, they think of Saturn, but there are actually five bodies in our solar system known to have them. Rings of gas and dust also encircle Jupiter, Uranus, and Neptune along with a "centaur", Chariklo, an homage to the mythological Greek creature which was a hybrid of man and beast to note the unclear dual nature of small, rocky bodies that possess qualities of both asteroids and comets.
Microbial communities in different regions of the Pacific Ocean displayed strikingly similar daily rhythms in their metabolism despite inhabiting extremely different habitats, according to a new study.
From the nutrient-rich waters off California to the nutrient-poor waters north of Hawai'i, dominant photoautotrophs - light-loving bacteria that need solar energy to help them photosynthesize food from inorganic substances - appear to initiate a cascade effect wherein the other major groups of microbes perform their metabolic activities in a coordinated and predictable way. As expected, different photoautotrophs dominated the coastal versus open ocean but many other heterotrophic bacterial groups were common to both habitats.
Adverse Drug Reactions are the biggest safety concern in the health field and they refer to harmful and unintended effects of drugs administered for the prevention and treatment of illness, both at normal dosages and in cases of incorrect usage or errors in medication. They are the fourth highest cause of death for patients in U.S. hospitals and up to 15 percent of hospital expenses are due to drug-related complications despite the fact that clinical trials are larger, longer and more expensive than ever and pharmacovigilance area is high.
Light can be used to activate normal, non-genetically modified neurons through the use of targeted gold nanoparticles, report scientists from the University of Chicago and the University of Illinois at Chicago. The new technique, described in the journal Neuron on March 12, represents a significant technological advance with potential advantages over current optogenetic methods, including possible use in the development of therapeutics toward diseases such as macular degeneration.
Last week, prominent tech site Gigaom ceased operations with the terse note “Gigaom recently became unable to pay its creditors in full at this time”.
Started in 2006 by Om Malik, the site had raised about $40 million over that period to create a technology news site, an IT analysis business and another business running IT events. None of them could make enough money to cover the $400,000 a month needed to keep the business going.
Chitin is a molecule that forms hard structures like fungal cell walls and the exoskeletons of invertebrates such as insects and crustaceans. It forms a strong and pliable material that is made even stronger when complexed with other materials (such as proteins and minerals) to form the protective outer shells of insects and crustaceans.
A generation ago, environmental activists declared war on yet another field of science - astronomy.
A new telescope was going to disrupt a squirrel, they alleged, and so astronomy abandoned places in the U.S. like Arizona and began to move to Chile.
Environmentalists declared a victory against science but they don't understand systems, including ecological ones. Astronomy is a clean industry with people from all over the world and to keep it going means limiting light pollution - and another study has shown that light pollution is an unknown force.
