Human brain genes implanted into monkeys to make them smarter

Human brain genes implanted into monkeys to make them smarter

*Hard work really does pay off as scientists find grit, determination does lead to better grades, higher achievement in school A new study into the unique evolution of human intelligence has raised ethical concerns after Chinese scientists implanted human brain genes into monkeys to boost their development. Researchers inserted human versions of MCPH1, a gene that scientists believe plays a role in the development of the human brain, into 11 rhesus monkeys. They found the monkeys’ brains — like those of humans — took longer to develop, and the animals performed better in tests of short-term memory as well as reaction time compared to wild monkeys.However, the monkeys did not grow bigger brains than the control group.The test, the latest in a series of biomedical experiments in China to have fuelled medical ethics debates, has already drawn ethical concerns, and comparisons with dystopian sci-fi ‘Planet of the Apes’. It was conducted by researchers at the Kunming Institute of Zoology and the Chinese Academy of Sciences, working with US researchers at the University of North Carolina.The study was published last month in Beijing-based journal National Science Review.“Our findings demonstrated that transgenic nonhuman primates (excluding ape species) have the potential to provide important — and potentially unique — insights into basic questions of what actually makes human unique,” the authors wrote. The monkeys underwent memory tests requiring them to remember colours and shapes on a screen, and were subjected to Magnetic Resonance Imaging (MRI) scans.Only five of the monkeys survived into the testing stage.The authors said the rhesus monkey, though genetically closer to humans than rodents, is still distant enough to alleviate ethical concerns. However, some questioned the ethics of the experiment.“You just go to the ‘Planet of the Apes’ immediately in the popular imagination,’ said Jacqueline Glover, a University of […]

How (properly) wasting time at work increases productivity

How (properly) wasting time at work increases productivity

by Aytekin Tank If you’ve ever watched a professional tennis match, you know how much stamina the sport requires. From thigh slaps to squats to light jumps, players will do just about anything to maintain their high energy and laser-focus. A crucial part of the match, however, occurs in the brief pause between games: the 90-second changeover break, when players rest before switching sides. Watch closely, and you’ll see how players make the most of these precious moments: burying their heads under a towel to meditate, changing their racquets, or fueling up on water and energy drinks. Some players, like the great Serena Williams, have even sipped a quick coffee before returning to the court. Whatever their method, these pro athletes understand the value of a break. A brief reprieve can provide a fresh surge of energy and motivation for the next game. Much like a tennis match, the workday can also be a daunting mental and physical challenge, especially if you want to perform your best throughout the day. In addition to finding your optimal work hours, taking multiple breaks can increase your productivity all day long. I’ll repeat that for emphasis: Taking breaks can increase productivity. Our workaholic culture and the business epidemic tend to villainize time-wasting behaviors during work — like leisurely lunches and web browsing — but research proves that breaks can enhance your performance, on many levels. Brief periods of distraction have been shown to improve both decision-making and creativity. On the other hand, prolonged attention to a single task can actually hinder performance. Pulling an all-nighter for one assignment? Not such a good idea after all. There’s also evidence that waking periods of mental rest can improve memory formation. Apparently, during rest periods, your brain reviews and ingrains what it previously learned. Without […]

E-biking can improve mental health and wellbeing in older people

E-biking can improve mental health and wellbeing in older people

E-biking is beneficial for the over 50 population ( iStock ) Getting on your bicycle can give you an enormous sense of freedom and enjoyment. It can increase your independence and knowledge of the local area, and improve your access to the natural (or urban) environment. It can also be highly nostalgic – reminding you of your childhood cycle rides and the joy of being young. But beyond the feelgood factor, can cycling actually make any difference to mental abilities and wellbeing? This was something our new study aimed to investigate – specifically looking at cycling among older adults . While most studies incorporate exercise in a gym situation, our study wanted to examine the impact of cycling in the real world – outside a controlled environment. So older adults, aged 50 and above, were asked to cycle for at least an hour and a half each week for an eight-week period. Participants either cycled on a conventional pedal bike , on an electrically assisted “ e-bike ” or were instructed to maintain their regular non-cycling exercise routine as a comparison group. Mental abilities, mental health and wellbeing were measured before and after the eight-week cycling period. Ford joins Frankfurt automakers in debuting e-bike Mental boost Exercise is thought to improve mental functioning through increased blood flow to the brain – as well as encouraging regrowth of cells, specifically in the hippocampus. This is known to be an area associated with memory. So it was expected that the greater physical exertion required for pedal cycling, compared to cycling an e-bike with a motor, would result in greater benefits to mental functioning. One of the tasks we used to measure mental ability is the “ Stroop test ”. The task involves participants being shown the name of a colour printed […]

Should You Try the Mediterranean Diet? We Examine the Evidence

Should You Try the Mediterranean Diet? We Examine the Evidence

— Please Note: This article is presented for informational purposes only and is not meant to diagnose or treat any illness. If you have any health concern, see a licensed healthcare professional in person. The Mediterranean diet has long been touted as one of the best. In fact, U.S. News and World Report named it the best diet overall compared to 41 different diets. The Mediterranean diet was also named the best plant-based diet, best diet for healthy eating, best diet for diabetes, and easiest diet to follow. Some studies even suggest it can help you live longer ( 1 , 2 ). But is this diet really the best diet for you? Here, we take a closer look at the origins of the diet and the current scientific evidence to see if the Mediterranean diet is all it’s cracked up to be. What is the Mediterranean Diet? The Mediterranean diet is a largely plant-based diet that draws from food traditions from countries along the Mediterranean coast. Origins of the Mediterranean Diet The Mediterranean diet has been studied for decades, but it’s only became popular in non-Mediterranean countries since the 1990s. It was first introduced with the Seven Countries Study , an international epidemiological study that began in 1958 and is still active today. The study, led by Dr. Ancel Keys, linked traditional Mediterranean diets (and specifically diets that include large amounts of olive oil ) with reduced risk for coronary heart disease ( 3 , 4 ). Keys and his wife published their findings on traditional Mediterranean diets and heart health in 1975. Dr. Keys remained a Mediterranean diet advocate and an active researcher for much of his life. He died just before his 101st birthday. The Mediterranean diet as we know it today isn’t necessarily the same […]

High-fat foods you should be eating more of (they’re actually really good for you)

High-fat foods you should be eating more of (they’re actually really good for you)

( Natural News ) Contrary to popular belief, fats could be healthy, depending on its source. For example, fats from processed foods, fried foods, and baked goods are harmful to your health. On the other hand, fats found in natural foods are actually healthy and nutritious. Here are some of the healthy high-fat foods you need to include in your diet. Avocados: Commonly used in making guacamole, avocados are rich in healthy fats and can fight inflammation, which is linked to cardiovascular disease. Studies show that eating avocados can regulate your cholesterol, blood pressure, and triglyceride levels. In addition, you need to consume healthy fats for your body to absorb fat-soluble vitamins A, D, E, and K. However, when eating avocados, keep your overall calorie intake in mind, as one avocado contains about 320 calories. (Related: Top 8 Healthy Fats to Include in any Diet, be it Muscle Building or Weight Loss .) Olive oil: Many studies show that olive oil can lower your risk for cancer, diabetes, and heart disease. It contains compounds called oleic acid and secoiridoid that slow the aging process. When buying olive oil , choose extra virgin olive oil because it is extracted using natural methods. Fatty fish: Fatty fish – such as anchovies, herring, salmon, and sardines – contains omega-3 fatty acids, which are great for keeping your brain healthy and fighting inflammation and chronic disease. Eggs: Eggs are thought to increase cholesterol levels, but research has proven that cholesterol from eggs does not really affect a person’s cholesterol levels. In fact, eating eggs for breakfast can make you feel full and satisfied for longer periods. Nuts: Nuts are rich in nutrients like amino acids, vitamin E, and unsaturated fatty acids. Research shows that eating an ounce serving of nuts every day can […]

Omega-3s are a potent way to treat depression without resorting to dangerous prescription medications

Omega-3s are a potent way to treat depression without resorting to dangerous prescription medications

( Natural News ) There are many natural ways to remedy poor mood and depression that do not involve the use of pharmaceutical drugs. One of these alternative approaches is to eat larger amounts of healthy foods that are rich in omega-3 fatty acids. Scientific research shows that the intake of omega-3 fatty acids in a diet influences the risk of depression. People who eat more omega-3-rich foods appear to have lower risks of falling into a depressed mood. The fatty acids achieve their natural antidepressant effects through several means. Omega-3s can raise the activity of CNS seratonin, reduce the risk and severity of inflammation, and stop phosphatidyl-inositol from sending signals that bring about depressive moods. They can even increase the variations between heartbeats. (Related: Omega-3 supplementation lessens symptoms of depression in people with chronic heart failure .) The natural, healthy equivalent of today’s antidepressant drugs Furthermore, omega-3 fatty acids seem to stop immune cells from releasing pro-inflammatory cytokines in the brain. This is similar to the means by which selective serotonin reuptake inhibitors (SSRI) and tricyclic antidepressant drugs improve the mood of patients suffering from depression . The acute phase of severe depressed mood has been observed to cause a spike in the release of cytokines. When those inflammation-causing molecules reach the brain, they disrupt the carefully regulated metabolism of serotonin in the organ. The disruption reflects changes in the mood of depressed individuals.

The fatty acids have demonstrated their ability to affect the release of similar cytokines in the heart, […]

Running Makes My Stress Melt Away, So I Asked a Doctor If There’s Actually a Link

Running Makes My Stress Melt Away, So I Asked a Doctor If There's Actually a Link

Group of diverse adult females trail running as the sun sets behind them Cardio used to be the be-all, end-all of my fitness routine. Specifically, running. It wasn’t until an injury sidelined me (turns out your knees don’t love running five miles a day) that I found high-intensity interval training (HIIT), weight training, and swimming. Changing up my fitness routine helped me get the physical results I wanted and I eventually realized that I didn’t actually have to run to maintain my fitness. Yet, there was one major reason why quitting altogether was never an option. It has to do with mental health, namely stress relief and overall sanity. In terms of keeping me calm and relieving stress, nothing is more effective than running. That goes for the good runs, when my body is in perfect sync, nothing hurts, and my mind gets to wander without a care in the world, and the bad ones, when my Achilles starts pinging, my knees ache, my sides cramp, and I’m grumpy and unfocused. One is more enjoyable, but they both leave me noticeably calmer than when I started. They both make my problems seem smaller, more manageable, and less important. Why Does Running Relieve Stress? Running is often touted as a way to relieve stress , and the deeper mental health benefits of cardio, and especially running, are just starting to be explored. One recent study, performed on mice, actually showed a possible connection between cardio and dementia prevention . But it’s one thing to read about mental benefits and another to experience them for yourself. It’s the ultimate brain hack. Really? All I have to do to feel better is go for a run? According to Douglas Noordsy, MD, a sports psychologist at Stanford Health Care, it’s based in biology. […]

These Plant Based Fragrances Are Designed To Spark Positivity And Good Vibes

This post is brought to you by Plant Therapy , the essential oil experts. The opinions and info presented here are completely our own. Have you ever smelled something that instantly makes you feel all warm and fuzzy inside? It’s no secret that scents and the way we respond to them is a powerful thing. They can energize us, help us to focus or feel relaxed, comfort us and even affect our emotions. And what about the way a scent can instantly connect us to a memory as if it were yesterday? For me, the smell of freshly baked apple pie can instantly transport me back to my grandmother’s kitchen, while the salty sea air is an eternal reminder of my childhood home on the water. So, how is it we’re so deeply connected to scent? It all has to do with our brains. While senses like sight, hearing, touch and taste are processed in the “thinking” part of our brain, scent molecules are sent to the olfactory bulb instead. The olfactory bulb happens to also be directly linked to the part of the brain that stores memories and processes emotions. But the real power these scents hold over us lies within our brain’s ability to connect scents to the memories stored there. When we’re repeatedly exposed to a specific scent along with a meaningful person, place, thing or experience that our brain creates these scent paired memories that can be strikingly vivid. Referred to as conditioned learning, it’s the same reason why the smell of apple pie fondly reminds me of my grandmother or the smell of a the salty sea air can instantly transport me back to my childhood home on the water where I would spend my summers swimming, boating and fishing. It’s this incredible emotional […]
