Do you know why our eyesight is sharpest at dawn and dusk?

( Natural News ) If you’ve ever been up at the crack of dawn or still outside when dusk falls, you may have noticed your sight is sharper than usual. A German study says this is because your brain changes the way it interprets visual signals during sunrise and sunset, according to a New Scientist article . Study author Christian Kell explained that our brain is always hard at work in the background. But come dawn or dusk, this continual background activity drops in the visual cortex, the parts of the brain that interpret visual information. Thanks to this reduction in signal-to-background noise ratio, the human visual cortex is able to focus on perceiving poorly-lit surroundings and objects. That’s why we can see better despite the low levels of light during those times. “You are sensitizing your brain. A weak signal coming in will have a higher signal-to-noise ratio,” explained Kell, a neuroscientist at the Goethe University . He and his colleagues determined this through an experiment with 14 men. They asked the participants to spot a faint, flashing orange cross against a pitch black background at different times of the day. They reported that the participants succeeded the most in their task at around 8:00 a.m. and 8:00 p.m. (Related: Prevent vision loss by protecting your heart with a healthy diet .) Ancient humans needed improved vision during dawn and dusk to avoid predators The Goethe University research team scanned the brains of the participants six times from 8:00 a.m. to 11:00 p.m.. They found out that the brain shuts down background activity in the visual cortex during 8:00 a.m. and 8:00 p.m. Get more news like this without being censored : Get the Natural News app for your mobile devices.

Researchers create memory prosthesis that can boost recall in humans by around 40 percent

Researchers create memory prosthesis that can boost recall in humans by around 40 percent

( Natural News ) The human brain holds many mysteries, among which are the specifics of how exactly memories work. There are a lot of different theories as to how the brain operates as far as memory as a function is concerned, but now researchers have finally made some real progress towards a better understanding of it. To be more specific, a group of scientists from the Wake Forest Baptist Medical Center and the University of Southern California (USC) have managed to develop a new kind of “prosthetic system” which is said to use an individual’s memory patterns to tap into the brain’s natural ability to encode and recall memory. The researchers shared the details of their method in a paper titled , “Developing a hippocampal neural prosthetic to facilitate human memory encoding and recall,” which was published recently in the Journal of Neural Engineering . Their study looked at the short-term memory of the participants, which ended up showing significant improvement – about 35 to 37 percent – over the baseline measurements by the end of all tests and experiments. According to Dr. Robert Hampson, a professor at the Wake Forest Baptist Medical Center and the lead author of the study, the method they used to artificially boost the short-term memory performance of study participants is something that has never been done before. “This is the first time scientists have been able to identify a patient’s own brain cell code or pattern for memory and, in essence, ‘write in’ that code to make existing memory work better,” he explained, “an important first step in potentially restoring memory loss.” (Related: Want to improve your memory or ability to concentrate?

10 Yummy, brain-boosting foods that prevent neurocognitive decline

10 Yummy, brain-boosting foods that prevent neurocognitive decline

( Natural News ) For a lot of people, the concept of growing old isn’t thrilling because of one thing: cognitive decline which is one of the hallmark signs of aging. In particular, memory loss, forgetfulness, a decreased ability to maintain focus, and reductions in problem-solving abilities are all part of the cognitive decline. Some cases, however, are more severe, progressing into Alzheimer’s disease and other forms of dementia. That doesn’t mean that you should just wait for the condition to take over. Here are some foods that you (or your loved ones) can eat to support brain function and prevent mild cognitive decline. (h/t to NaturalHealth365.com . ) Cucumbers – According to several studies, this refreshing fruit contains a flavonoid called fisetin, which stops memory loss and age-related cognitive decline. In one study, the brain-boosting benefits of fisetin were evident, even in the presence of amyloid plaques – an indicator for the onset of Alzheimer’s disease. Strawberries – Besides fisetin, which strawberries also have, these delicious berries are rich in antioxidants and polyphenols that have anti-inflammatory properties. Indeed, a study from Brigham and Women’s Hospital found that older women who regularly ate a cup of strawberries each week slowed down the effects of cognitive aging by up to two and a half years. Grapes – These succulent fruits, especially the purple and red kinds, contain anthocyanins, an antioxidant known to prevent free radical damage in the brain. In particular, resveratrol, a phenolic antioxidant also present in red wine, is a potent weapon against cognitive decline.

Blueberries – This superfood has been proven to prevent oxidative stress and promote the growth of new neurons in the brain, as well as improve learning, memory, and cognitive performance. […]

7 Reasons why you should start eating more blueberries

7 Reasons why you should start eating more blueberries

( Natural News ) Aside from being abundant in antioxidants , blueberries, dubbed the “king of antioxidant fruits,” offers a wide range of health benefits. In fact, several studies have proven that simply eating less than one cup of these berries every day can help lower your risk of developing cancer and heart disease. Blueberries can even help slow brain aging. The 7 benefits of eating blueberries Blueberries can boost insulin sensitivity – Data from a study in The Journal of Nutrition determined that blueberries contain bioactive compounds that can help improve insulin sensitivity. In the study, researchers grouped 32 “obese, non-diabetic, insulin-resistant patients” into two; one group consumed smoothies with 22.5 g of blueberry bioactives while the other had placebo, twice a week. After six weeks the group that drank the smoothies with blueberry bioactives improved their insulin sensitivity by a factor of four compared to the placebo group. Blueberries can help keep the brain young – According to a study published in the Annals of Neurology, the anthocyanins in blueberries can help slow brain aging. Researchers from Harvard University measured cognitive function in 16,010 participants aged 70 years and older in the Nurses’ Health Study . Using data from dietary questionnaires, the researchers found that consuming more blueberries can slow cognitive decline by up to 2.5 years. The berries can also slow brain aging in younger individuals, such as children aged eight to 10 years old. Blueberries can lower blood pressure – In a study published in the Journal of the Academy of Nutrition and Dietetics , researchers gave a group of post-menopausal women with pre-hypertension (or stage one hypertension) 22 g of freeze-dried blueberry powder daily, which was equivalent to a cup of fresh blueberries. After eight weeks there was a notable decrease in the women’s […]

MIND OVER GENES: Meditation improves your blood pressure by literally altering gene expression in your body’s cells

MIND OVER GENES: Meditation improves your blood pressure by literally altering gene expression in your body’s cells

( Natural News ) Meditation is often thought of as a simple way to relax and clear your mind — and no one would ever try to argue that point. But, it turns out that the benefits afforded by practicing meditation extend far beyond the ephemeral. Indeed, long-term health benefits can be had, by just taking a few minutes a day to spend on your inner self. The impact of meditation on patients struggling with hypertension (high blood pressure) has recently shed light on how beneficial taking that time for yourself can really be. While it’s well-documented that meditation and other relaxation techniques have effects at both the physiological and psychological level, little is known about how they exact these actions. Researchers from Beth Israel Deaconess Medical Center (BIDMC), Massachusetts General Hospital (MGH), and the Benson-Henry Institute for Mind Body Medicine at MGH worked together to analyze the genes associated with responding to relaxation techniques and their findings “sheds light on the molecular mechanisms by which these interventions may work to lower blood pressure.” Co-senior author Randall Zusman, M.D., Director of the Division of Hypertension at MGH commented, “Traditionally, hypertension is treated with pharmacologic therapy, but not all patients respond to drug therapy, and many experience treatment-limiting side effects.” “In these patients, alternative strategies are invaluable. In this study, we found that the relaxation response can successfully help reduce blood pressure in hypertensive patients who are not taking medication,” he contended further.

Music improves your brain: Study finds musicians are better at solving problems and making decisions

Music improves your brain: Study finds musicians are better at solving problems and making decisions

( Natural News ) Music has charms to soothe the savage beast, so wrote the playwright-poet William Congreve. Science has shown that music can also heal and slow down the aging process. But new research has found one more reason to learn this universal language: Music can actually make you smarter . Researchers from the University of Granada observed the neurological changes that occur due to prolonged musical training. The first-of-its-kind study showed that music helps people solve problems better. That’s because musicians enjoy higher neural connectivity than non-musicians, and therefore have an easier time with mental activities. Scientists from the Mind, Brain and Behaviour Research Centre and the Department of History and Music Science studied 142 students in many music schools like the “Victoria Eugenia” Royal Conservatory of Music in Granada, the Conservatory of Music in Málaga, and the University of Granada’s Bachelor’s Degree in the History and Science of Music department. The students had formal music training for at least ten years, and learned to play an instrument in the process. Participants underwent a magnetic resonance imaging (MRI) along with several neuro-psychological, behavioral, and hearing tests. A laterality test determined if they were left or right-handed. Results showed that musicians have higher neural connectivity than non-musicians in the default mode network, the brain system which leads to more complex cognitive processes like making crucial decisions or figuring out daily problems.

Sitting down too much can make you stupid — new research says a sedentary lifestyle alters areas of the brain linked to memory

Sitting down too much can make you stupid — new research says a sedentary lifestyle alters areas of the brain linked to memory

( Natural News ) You watch what you eat and make sure you get a good night’s sleep. You regularly step outdoors to get your daily dose of natural vitamin D from the sun. But on weekdays, you work an eight-hour job that requires you to stay tied to your desk practically the whole time. According to a new study, this unhealthy lifestyle could offset most everything you’ve done to stay healthy. Researchers from the University of California, Los Angeles (UCLA) found that sitting too long, like smoking, carries the same risks. These include heart disease, diabetes, and even premature death. In their quest to see if a sedentary lifestyle affects brain health, researchers gathered 35 people aged between 45 to 75. The research team asked them about their physical activities and the usual number of hours they spent sitting during the previous week. Each of the participants underwent a high-resolution MRI scan, which gave a detailed view of the medial temporal lobe (MTL) a part of the brain responsible for creating new memories. The researchers discovered that sedentary behavior can significantly predict thinning of the MTL . They also found out that the harmful effects of sitting to brain health are irreversible. Not even high levels of physical activity can compensate for the damage that has been done. Our present-day lifestyle, characterized by the prevalence of gadgets that make us sit down for longer periods of time, makes sedentary behavior part of our daily routine.

Sad robot: Expert says that robots could become so life-like that they will develop mental illnesses too

Sad robot: Expert says that robots could become so life-like that they will develop mental illnesses too

( Natural News ) It’s fair to say that our world has reached a point where technology is so advanced that robots are almost expected to be lifelike – but what about robots that develop mental illnesses, hallucinations and depression like human beings do? Is this just science fiction, or can we really expect artificial intelligence to grow even more similar to humans in the not-so-distant future? Back in March, New York University hosted a symposium in New York City called Canonical Computations in Brains and Machines, where a group of neuroscientists and experts in the field of artificial intelligence spoke about overlaps in the ways in which human beings and machines think and process information. According to one of these neuroscientists – Zachary Mainen of the Champalimaud Centre for the Unknown – we might expect advanced machines to soon be able to experience some of the same mental problems that people do. “I’m drawing on the field of computational psychiatry, which assumes we can learn about a patient who’s depressed or hallucinating from studying AI algorithms like reinforcement learning. If you reverse the arrow, why wouldn’t an AI be subject to the sort of things that go wrong with patients?” Mainen said. The neuroscientist went on to explain that mental illnesses like depression and hallucinations depend on a chemical in the brain called serotonin, and if serotonin is being used to help intelligence systems solve a more general problem, “then machines might implement a similar function.” In other words, if serotonin can go wrong in humans, it could also go wrong inside of a machine.

Five so-called “conspiracy theories” that are actually supported by mainstream science

Five so-called “conspiracy theories” that are actually supported by mainstream science

( Natural News ) Telling the truth about a scandal that hasn’t been approved by the legacy media and their owners often yields a predictable result: You’ll be labeled a conspiracy theorist — even when there is plenty of evidence to support the truth. Comfortable lies may help some people sleep at night, but the truth is that many supposed “conspiracy theories” are actually real, and are supported by science . Who would have thought? Here are five truths that are widely misrepresented as conspiracy theories, and the evidence which supports them: 1. Atrazine disrupts, damages the endocrine system Atrazine is on the fast-track to becoming one of the most widely used pesticides in the United States. And because of this, there is a high amount of it in groundwater. It is consistently detected in public water supplies — which in and of itself is really quite concerning. But when the profound potential for this toxic chemical to spur endocrine disruption is taken into account, atrazine becomes downright frightening . Research led by Dr. Tyrone Hayes, a scientist from the University of California at Berkeley, has shown that in frogs, atrazine is capable of causing lasting endocrine damage. In males, the disruption to endocrine function can be so severe that it results in chemical castration. In one study, Hayes exposed 40 tadpoles to water tainted with atrazine, at a concentration of 2.5 parts per billion — well within the EPA’s allotment for drinking water. Nearly one-tenth of the tadpoles that were reared in the atrazine-laden water became “functionally female,” according to Hayes. Despite reportedly being born male, they ended up producing eggs.
