Cell Phones with Cameras That Detect Cancer?

15 Dec

It seems like science fiction, but some researchers say it will be a reality in the near future.

How?  It’s because Mother Nature can already “see” cancer and recently, scientists figured out how she does it.

This is pretty amazing.  The Mantis Shrimp is known as one of the most ferocious predators –pound-per-pound — in the ocean.  What it lacks in size, it more than makes up for in its toughness and incredible power.

But what is even more amazing are the eyes of the Mantis Shrimp.  According to researchers in Australia, the Mantis shrimp has a very unique pair of “compound eyes.”

As reported in ScienceAlert: “This type of eye is superbly tuned to detect polarised light – a type of light that reflects differently off different types of tissue, including cancerous or healthy tissue.”

Natural Light in the Office May Benefit Health…

10 Nov

Many people are practically scared to death of sun exposure because of the risk of skin cancer. Some “experts” even recommend wearing protective clothing or sunscreen whenever you may be exposed to sunlight. However, this may not be the best advice because sunlight is essential to our health. Sunlight is how we humans produce vitamin D, and studies suggest it has other beneficial effects as well.
Now, a study published in the Journal of Clinical Sleep Medicine (June 2014) shows that even getting natural sunlight through a window can be beneficial. The study conducted by a team of scientists from Northwestern Medicine and the University of Illinois at Urbana-Champaign reports that office workers with more light exposure at the office had longer sleep duration, better sleep quality, more physical activity, and a better quality of life compared with office workers with less sun light exposure in their workplace.
According to the lead author of the study Dr. Phyllis Zee, “There is increasing evidence that exposure to light during the day, particularly in the morning, is beneficial to your health via its effects on mood, alertness, and metabolism.” Employees with windows in the workplace received 173 percent more white light exposure during work hours and slept an average of 46 minutes more per night than employees who did not have the natural light exposure at their workstations.
Workers in offices with windows also tended to be more physically active than those without window in their offices. Workers without windows reported poorer scores on quality of life measures related to physical problems and vitality, as well as poorer outcomes on measures of overall sleep quality and sleep disturbances. The researchers emphasize the importance of architects using this information in the planning of new buildings. They add that workstations should be within 20-25 feet (~6-8 meters) of windows, because daylight from side windows almost vanishes after that distance.

Popular Pain Medication No Better Than a Placebo…

6 Nov

You may find this shocking, especially if you take Tylenol — also known as acetaminophen or paracetamol — in an effort to relieve your back pain. A new study in The Lancet (July 24, 2014) begins with, “Regular paracetamol is the recommended first-line analgesic for acute low-back pain; however, no high-quality evidence supports this recommendation. We aimed to assess the efficacy of paracetamol taken regularly or as-needed to improve time for recovery from pain, compared with placebo in patients with low-back pain.”
Wow. It’s 2014 and acetaminophen is often the first thing recommended for low-back pain, and there is no scientific evidence it helps.
What did the study discover? Using data from 235 primary care centers in Australia collected between 2009 and 2013, the researchers write, “Our findings suggest that regular or as-needed dosing with paracetamol does not affect recovery time compared with placebo in low-back pain, and question the universal endorsement of paracetamol in this patient group.”

Eat protein to decrease your stroke risk.

29 Sep

According to The Telegraph, scientists followed 254,489 people for an average of 14 years and concluded that “Eating a high protein diet significantly lowers the risk of stroke and could prevent 10,000 deaths in Britain every year… Consuming as little as one chicken breast or a salmon fillet – the equivalent of 20g – [a day] reduces the risk of stroke by 20 percent.”
The article quotes the study’s author, Dr. Xinfeng Liu, as saying, “If everyone’s protein intake were at this level, that would translate to more than 1.4 million fewer deaths from stroke each year worldwide, plus a decreased level of disability from stroke.”
Dr. Liu adds that people should avoid red meat, as other studies have associated with increased stroke risk. In other words, stroke may be reduced by replacing red meat with other protein sources, such as fish or chicken. It’s also worth noting that the reduced risk of stroke was stronger for animal proteins than vegetable proteins.

Want to be More Creative? Do This…

11 Aug

A new study published in the Journal of Experimental Psychology: Learning, Memory and Cognition claims to have made a remarkable discovery. As reported by Business Insider, “Participants who went for a walk saw an 81% increase in tests measuring divergent thinking, a thought process associated with creativity in which you generate a lot of ideas.”
Walking has been practiced by top thinkers to generate ideas and solve problems for centuries, perhaps even millennia. The list of “walkers” is like a who’s who in the intellectual and business world. Aristotle, Friedrich Nietzsche, Steve Jobs, and Mark Zuckerberg were/are all walkers, and there are plenty more. Walking tends to stimulate your creative senses in many ways. One way is that walking simply “activates” or “awakens” your body and brain. Sitting around tends to deaden your senses. In other words, sitting slows you down and almost makes you numb to new thoughts and ideas. Walking (even if it’s just around a little room) gets the blood flowing and gets both your body and brain in thinking-mode, ready to produce and/or receive fantastic new ideas. The walk also gives you a new perspective. Perspective is extremely important to creative thinking and problem solving.
Walks do one more very important thing: They keep your spine moving and help reduce back pain. Sitting for long periods of time not only kills creativity, it slowly destroys your back. Bad posture and the forces of gravity cause joint “creep” that can cause serious problems over time. If you want to be even less creative, try thinking while you suffer from chronic back pain. Staying physically active is one of the best things you can do for both your mental and physical health.
And it’s not good enough to simply exercise at night after you sit all day at a desk. It is best to take frequent breaks and go for a walk, even if it is just in a little circle next to a tiny cubicle. Doing this little activity several times a day can pay huge dividends and help you avoid many health problems over the next 10, 20, or 30 years.

WARNING: Coughs and Sneezes Travel Much Further than Expected!

9 Jul

Researchers have known for some time that coughs and sneezes travel quite a distance. You have probably seen slow motion videos showing the huge droplet mist caused during a sneeze. Well, new research conducted by researchers at Massachusetts Institute of Technology (MIT) shows that coughs and sneezes have associated nearly invisible gas clouds that travel much further than previously thought. According to Dr. John Bush, a Professor of Applied Mathematics at MIT, “When you cough or sneeze, you see the droplets, or feel them if someone sneezes on you. But you don’t see the cloud, the invisible gas phase. The influence of this gas cloud is to extend the range of the individual droplets, particularly the small ones.” The new research shows the smaller particles travel between 5 to 500 times further! Even more shocking is that because particles are suspended in a gas, they are much more likely to be picked up by air circulating systems such as heating and air conditioning vents. This can spread “germs” throughout an entire building, just about instantly. Oh the horror!!! Or is it?
The first thing to understand is while this research is new, the distance traveled by sneezes and coughs is not. In other words, “germs” from sneezes and coughs have been suspended in small gas clouds that travel large distances and possibly through heating and air conditioning vents since there have been sneezes, coughs, and vents. Researchers (and you and I) knowing about it is the only thing that is new. So, two things are clear. (1) Knowing about it does not mean more people will get sick and (2), which is the most important, this is just further evidence that “germs” are everywhere. Everyone breathes them in constantly. If you are breathing “germs” in all day, and germs make you sick, then why aren’t you constantly sick?
The answer is quite simple. Germs will never be eradicated, and they should not be. They are an essential part of our ecosystem. Beyond living in a bubble, you are always going to be in contact with germs. So, the best way to deal with “germs” is to make sure your immune system is functioning to your genetic potential. This is because “germs” easily invade a body with a weak or weakened immune system, take hold, and make that person sick. On the contrary, “germs” are easily fought off by a strong, well functioning immune system. This is why), holding all other factors constant, people who do not get enough sleep, drink excessively, smoke cigarettes, have high stress levels, and eat a poor diet (loaded with processed food and sugar) are more likely to get sick when exposed to the same “germs.” Even worse, their sickness can be worse and last longer which is all the more reason to focus on the things you can control like diet, sleep, and stress reduction.
