Bioquimica The human microbiome: Me, myself, us WHAT’S a man? Or, indeed, a woman? Biologically, the answer might seem obvious. A healthy adult human harbours some 100 trillion bacteria in his gut alone. And it really is a system, for evolution has aligned the interests of host and bugs. That bacteria can cause disease is no revelation. A bug’s life One way to think of the microbiome is as an additional human organ, albeit a rather peculiar one. The microbiome, too, is organised. Specialised; but not monotonous. That detail is significant. This early nutritional role, moreover, is magnified throughout life. The fat of the land This role in nutrition points to one way in which an off-kilter microbiome can affect its host: what feeds a body can also overfeed or underfeed it. Experiments on mice suggest this is not just a question of the bacteria responding to altered circumstances. Having shown that gut bacteria are involved in obesity, Dr Gordon wondered if the converse was true. The diabetes in question is known as type-2.
Modafinil Modafinil is a wakefulness-promoting agent[3] (or eugeroic) that is approved by the United States' Food and Drug Administration (FDA) for treatment of wakefulness disorders such as narcolepsy, shift work sleep disorder,[4][5] and excessive daytime sleepiness associated with obstructive sleep apnea.[6] In English-speaking countries it is sold under the brand names: Alertec (CA), Modavigil (AU, NZ), and Provigil (IE, ZA, UK, US). Medical uses[edit] Approved uses[edit] In 1998, modafinil was approved by the U.S. Food and Drug Administration[7] for the treatment of narcolepsy and in 2003 for shift work sleep disorder and obstructive sleep apnea/hypopnea[8] even though caffeine and amphetamine were shown to be more wakefulness promoting on the Stanford Sleepiness Test Score than modafinil.[9] EEG studies indicate caffeine, amphetamine, and modafinil to all be theta wave reducing but only modafinil to be Alpha wave promoting during wakefulness as well as theta wave increasing during sleep.[10]
Medios 100 Very Cool Facts About The Human Body The Brain The human brain is the most complex and least understood part of the human anatomy. There may be a lot we don’t know, but here are a few interesting facts that we’ve got covered. Nerve impulses to and from the brain travel as fast as 170 miles per hour. Ever wonder how you can react so fast to things around you or why that stubbed toe hurts right away? It’s due to the super-speedy movement of nerve impulses from your brain to the rest of your body and vice versa, bringing reactions at the speed of a high powered luxury sports car.The brain operates on the same amount of power as 10-watt light bulb. Hair and Nails While they’re not a living part of your body, most people spend a good amount of time caring for their hair and nails. Facial hair grows faster than any other hair on the body. Internal Organs Though we may not give them much thought unless they’re bothering us, our internal organs are what allow us to go on eating, breathing and walking around. Bodily Functions Senses
How Marijuana Affects Memory: It's Not The Neurons Getting mice stoned can actually result in important scientific discoveries. Research published in March in Cell magazine reveal how marijuana impairs working memory, the short-term memory we use to hold on to and process thoughts. The classic example is of the stoner who forgets the point he was making, mid-sentence. To study exactly how cannabis affects working memory in such a fashion, Giovanni Marsicano of the University of Bordeaux in France and his colleagues removed cannabinoid receptors from neurons in mice, reports Ruth Williams at Scientific American. These receptors are proteins that respond to marijuana's chief psychoactive ingredient, THC (tetrahydrocannabinol). The mice whose cannabinoid receptors had been removed from their neurons were just as forgetful as regular mice when given THC; that is to say, they were just as bad at memorizing the position of a hidden platform in a water pool.

Matematicas collective intelligence course aims to improve responses to COVID-19, other crises The GovLab at NYU Tandon teams with 11 global institutions to offer free classes on effective disaster response BROOKLYN, New York, April 06, 2020 (GLOBE NEWSWIRE) -- Working with 11 partner institutions around the world, The Governance Lab (The GovLab) at the New York University Tandon School of Engineering today launches a massive open online course (MOOC) on “Collective Crisis Intelligence.” The course is free, open to anyone, and designed to help institutions improve disaster response through the use of data and volunteer participation. Thirteen modules have been created by leading global experts in major disasters such as the post-election violence in Kenya in 2008, the Fukushima nuclear plant disaster in 2011, the Ebola crisis in 2014, the Zika outbreak in 2016, and the current coronavirus. The course is designed to help those responding to coronavirus make use of volunteerism. More information on the courses is available at
How Hemp Got High If Genome Biology had been launched today, instead of 11 years ago, it might well have been given the alternative title of "Transcriptome Biology". While Genome Biology captured the millennial zeitgeist of genomics brought about by the project(s) to sequence the human genome, the breathtaking progress of this field in the intervening decade has brought us to a new frontier: the transcriptome. The development of RNA-seq, which applies high-throughput next-generation sequencing technology to cDNA generated from RNA samples, has resulted in an explosion of transcriptome sequences. Not only does RNA-seq benefit from higher sensitivity than microarrays, it also does not require the a priori knowledge needed for constructing chips; this flexibility has infused the transcriptome explosion with a biologically diverse character and encompassed many species not well covered by commercially available microarrays.
Homemade Bandages You may need to make a homemade bandage in an emergency situation when you have no ready-made first aid materials available. Some people also like to make their own bandages for cost or environmental reasons. Homemade bandages are much cheaper than over-the-counter alternatives, and allow you to use materials that would otherwise be thrown away. Making an Emergency Bandage Find some gauze to use as a dressing for the wound. How to Make a Roomy Slingback Fit Better Find some sticky tape. Cut or tear the gauze or paper towel into the right shape and size for the wound you are dressing. How to Tape a Hurt Toe Stick tape firmly over the dressing to hold it in position. Bandages for Your Medicine Cabinet Make a compress or rolled bandage out of an old white cotton sheet. Make a triangular bandage out of any strong cotton material. Cut a variety of widths from the legs of some old stretch jeans to make elastic bandages. Tips Warnings The Wrap Up
