4:26 PM | Fast Food Commercials Aimed At Kids 'Deceptive'
Fast food advertising doesn't emphasize healthy menu items enough, and by giving away toys in things like Happy Meals restaurants are being deceptive even by their own self-regulation standards, according to scholars who showed 100 children aged 3–7 years McDonald’s and Burger King children and adult meal ads, randomly drawn from ads that aired on national U.S. television from 2010–11. After seeing the ad, children were asked to recall what they had seen and transcripts […]

3:42 PM | Deadly Frog Fungus Dates Back To 1880s
A deadly fungus responsible for the extinction of more than 200 amphibian species worldwide has coexisted harmlessly with animals in Illinois and Korea for more than a century, a pair of studies have found. Amphibians in Illinois have been coexisting with the fungus Batrachochytrium dendrobatidis, or Bd, for at least 126 years without adverse effects seen in other parts of the world such as mass-die offs, according to research published Jan. 13 in the journal Biological Conservation. In a […]

2:55 PM | Ocean Tides Have Changed Significantly Over The Last Century
Ocean tides have changed significantly over the last century at many coastal locations around the world, according to a paper in Earth’s Future, and increases in high tide levels and the tidal range were found to have been similar to increases in average sea level at several locations.Average sea levels are rising but tide levels have undergone little change on decadal time scales, nor will they change much over the next century, so long-term changes in tides are not a concern in […]

2:30 PM | Planck Mission Challenges Einstein Again
From 2009 to 2013, ESA’s Planck satellite took measurements of the cosmic microwave background (CMB), radiation that originated approximately13 billion years ago, around 380,000 years after the Big Bang. Due to the expansion of the universe, this light is still observable today at microwave wavelengths across the entire sky so Planck surveyed the sky to map this ancient light. One result is that the standard model of cosmology remains an excellent description of the universe, unless the […]

2:00 PM | Artificial Lagoons In Swansea Can Harvest Energy From The Tides
The search for alternative energy sources in the age of climate change has overlooked tidal energy: a vast and unexploited worldwide resource.For three decades now, tidal lagoon schemes have been recommended as an economically and environmentally attractive alternative to tidal barrages. More recently, two proposals for tidal lagoons in Swansea Bay, Wales have emerged and there have been several reports documenting how such a project there could have the potential to harness significant energy […]

1:30 PM | Mars Lost An Ocean’s Worth Of Water
Four billion years ago, a young Mars had enough water to bury its whole surface under 400 feet of ocean, but it is more likely that, as on Earth, it pooled. In the case of Mars, it probably formed an ocean occupying almost half of Mars’s northern hemisphere, reaching a mile deep in some places.This new finding is based on detailed observations of two slightly different forms of water in Mars’s atmosphere. One is the familiar form of water, made with two hydrogen atoms and one […]

6:37 AM | Quantum Cryptography Core Question At The Heart Of Quantum Information Theory Answered?!?
Cryptography aims to secure communication. Eve should not be able to eavesdrop on the communication between Alice and Bob. Quantum cryptography is 100% secure, but it is unsatisfying if this security is merely promised by a still new and controversial theory. Who wants to trust their most important secrets to something that may be wrong? I am indebted to Matthew Saul Leifer, a researcher in the field of quantum information at the Perimeter Institute for Theoretical Physics, because the way he […]

4:14 AM | Oxytocin Nasal Spray Causes Men To Eat Fewer Calories
A synthetic nasal formulation of the hormone oxytocin reduced caloric intake in healthy men, particularly consumption of fatty foods, after a single treatment, a new study finds. The results, to be presented Sunday at The Endocrine Society's 97th annual meeting in San Diego, confirm those of animal studies showing oxytocin reduces food intake. Oxytocin nasal spray reportedly lowered the number of calories men consumed at a subsequent breakfast whether they were normal weight or overweight. In […]

3:40 AM | An Alternative To Medical Marijuana For Pain?
Medical marijuana is proliferating across the country due to the ability of cannabis ingestion to treat important clinical problems such as chronic pain. However, negative side effects and the development of tolerance limit the widespread therapeutic use of Δ9-tetrahydrocannabinol (Δ9-THC), the major psychoactive ingredient in cannabis. THC's side effects are produced via its actions at cannabinoid CB1 receptors in the brain. Thus, scientists theorized that an agent with similar […]

12:02 AM | Why computational cognitive scientists can continue their work despite rumors of their field's demise
The cognitive revolution (or better, information processing revolution) rejected the idea that behavior could be understood without reference to a contribution from the mind/brain.  Through decades of experimentation and theory development, we have come to appreciate that the mind/brain works by computing (or better, transforming) information available in the environment (or stored in the mind/brain itself) as a means to control behavior.  Call this the computational theory of mind.

8:01 PM | Was Neuroscience's Most Famous Amnesiac, "HM", A Victim of Medical Error?
According to a new paper, one of neuroscience's most famous case-studies came about as a result of a serious medical blunder. Henry Molaison (1926 - 2008), better known as HM, was an American man who developed a dramatic form of amnesia after receiving surgery that removed part of the temporal lobes of his brain. The 1953 operation was intended to treat HM's epilepsy, but it had the side effect of leaving him unable to form new memories. The consequences of HM's surgery are well known

7:18 PM | Not “just” crazy – Some psychoses caused by autoimmunity
Antibodies defend the body against bacterial, viral, and other invaders. But sometimes the body makes antibodies that attack healthy cells. In these cases, autoimmune disorders develop. Immune abnormalities in patients with psychosis have been recognized for over a century, but it has been only relatively recently that scientists have identified specific immune mechanisms that seem to […]

7:00 PM | Gut-Brain Health – What Neuroscientists Are Calling “A Paradigm Shift”
The trillions of microbes that inhabit your body are collectively called the microbiome. They outnumber your own cells ten to one and weigh up to twice weight of the average human brain. Most of them live in your gut and intestines, where they help to digest food, synthesise vitamins and ward off infection. The microbiome has […] The post Gut-Brain Health – What Neuroscientists Are Calling “A Paradigm Shift” appeared first on Your Brain Health.

6:55 PM | The Acrobatic Hijinks Of Praying Mantises Captured
When a young, wingless praying mantis jumps,  from take-off to landing is a mere tenth of second--literally faster than the blink of a human eye. During a jump, the insect's body rotates in mid-air at a rate of about 2.5 times per second. And yet, the jumps are precise. When mantises jump, they land on target every time. "This is akin to asking an ice skater who is rotating at the same speed as these mantises to stop suddenly and accurately to face a specific direction," says Malcolm […]

5:55 PM | Now I am become DOI, destroyer of gatekeeping worlds
Digital object identifiers (DOIs) are much sought-after commodities in the world of academic publishing. If you’ve never seen one, a DOI is a unique string associated with a particular digital object (most commonly a publication of some kind) that lets the internet know where to find the stuff you’ve written. For example, say you want […]

5:54 PM | Menopause Is One Of Nature's Greatest Mysteries
Most female animals die around the same time they stop reproducing, only humans and two types of whale continue to live for many years after giving birth to their last baby. But why?  Menopause is one of nature's greatest mysteries.  A new study says that female killer whales survive after menopause because they help their family members find food during hard times, though that could be more like keeping busy and staying relevant than being an evolutionary mandate. read more

4:56 PM | Is The UK Experiencing A Brain Drain?
Immigration continues to be one of the key issues in the build-up to the general election. The latest figures show a net flow of 298,000 into the UK. This is higher than when David Cameron’s government took office, despite his pledge to cut the number to the tens of thousands.But is this really bad news? Immigration is such an emotive issue that there is a tendency for the figures involved to be bandied about out of context. read more
