New Invention: A Flashlight that kills Bacteria

Recently, scientists invented a “flashlight” that can kill bacteria by beaming plasma at it. Plasma is a gas that can be created by electrical discharges and previous studies show that it effectively kills bacteria and viruses on skin.

During the test runs, scientists from China and Australia created bacteria that are highly antibiotic and heat-resistant to see what the flashlight can do. Results showed that after the bacteria was exposed to the flashlight for 5 minutes; they notice that it was able to eradicate the bacteria, even at the deepest layer. The flashlight is battery powered and portable making it easier for emergency medical personnel in disaster zones.

FDA says No on Banning BPA

Recently, the FDA has rejected a petition from environmentalists that would ban the plastic hardening chemical bisphenol-A (BPA) from all food and drink packaging. On March 30th, the FDA announced the petitioners did not present compelling scientific evidence that would validate the new restrictions on this chemical.

There are some evidence that BPA causes harm to the reproductive and nervous systems if exposed to this chemical. It is known that 90% of Americans have traces of BPA in their bodies, because if our constant exposure of bottles, canned food, and other containers. The FDA defended their decision by saying that those findings can’t be applied to humans and any study conducted so far are too small to be conclusive. The studies had researchers inject BPA into animals, but on the other hand, humans ingest the chemical through their diet over longer periods of time. Humans supposedly digest and remove BPA more quickly than any lab animal. The FDA are concerned that there might be a larger effect on young children, therefore are spending $30 million to conduct further studies.

Many companies aren’t waiting for the ban to happen as they are responding to consumer demand to remove BPA from their products. Some examples are Wal-Mart, Toys “R” Us and Campbell’s Soup.

The Older you are, the Better the Sleep

A new study found that the quality of sleep gets better the older we get, and that adults in their 80’s are having the best sleep than anyone else. There are many factors that affect sleep besides your biological age such as stress, illness and depression, but when those aren’t taken in account, elderly adults do not report sleeping problems compared to the younger adults.

The study asked 155,877 adults in a phone survey conducted by the Centers for Disease Control and Prevention where they were asked about their sleeping habits and general demographic questions such as race, health issues, and income. In general, women said that they had more sleep problems than men and health problems and depression are related with the worse sleep among all age groups.

Study Recommend Babies to Feed Themselves to Avoid Obesity

There’s a term for this—“baby-led weaning.” The definition is allowing infants “wean” themselves away from breast milk or formula by self-feeding tiny bits of cut-up foods, rather than being spoon-fed by their parents. The study had parents filled out surveys about their babies’ feeding and weaning practices, their infant’s favorite foods, and height and weight. There were 155 children aged 20 months to 6.5 years old in this study.

The results showed that on average, the baby-led group were at a healthy weight compared to the spoon-fed kids who were more likely to be overweight. The interesting part was that the finger-fed babies preferred to eat carbs (i.e. bread) over sweet foods and the spoon-fed kids liked sweet foods the most. The researchers also accounted for other factors for their weight such as family income and family history of obesity.

Researchers suggest that by having babies feed themselves, it may help babies become more aware of their own appetite and eating habits and discourage anxious parents from feeding their infants too much food.

Can a Blood Test Help Predict Your Death?

A new study reported in the Journal of the American Medical Association and the European Society of Cardiology Congress discovered a certain enzyme that could be linked to both heart disease and cancer. By measuring this enzyme in blood, it could serve as an early predictor of who is most likely going to die from these health problems.

The study had almost 2,000 participants joined in two separate long-term trials where the researchers measured the level of cathepsin S, an enzyme involved in breaking up proteins. They followed the participants for 12.5 years and found that, “those who have the highest level of cathepsin S were more likely to die than those with lower or half of those levels.”

It is yet to be clear how cathepsin S might be related to heart disease or cancer, but this study is the first to find a marker associated both these leading killers of U.S adults. Overall, it is too early to know if cathepsin S will be handy in predicting who has the greatest risk, but already pharmaceutical companies are keeping their eyes on the progress.

Does it Matter What Your Doctor Looks Like?

A new study conducted by the John Hopkins Bloomberg School of Public Health and the John Hopkins University School of Medicine found  out that a doctor’s body size had an influence on how he or she cared for their patients with weight problems. The researchers found that out of the 500 primary care physicians that was part of this study, 30% of normal weight physicians discussed losing weight with their patients while only 18% of the overweight doctors did.

They also found out that 93% of doctors would diagnose obesity in their patients if they believed that their own weight was equal to or less than that of their patients. The study also found that more than half of physicians were overweight or obese (53%) which is a similar percentage to the 64% of the U.S. adults that fall in the same category.

What was also surprising was that when overweight or obese doctors did discussed obesity issues with their patients, they were more likely than their normal weight physicians to prescribe anti-obesity medications (26% vs. 18%) rather than diet and exercise.

The researchers concluded that the behavior is subconscious and not intentional. This study suggest that the physical appearance of doctors can be a bigger factor to how patients are taken care of than realized.

Texting and Talking Slows You Down

A new study conducted by the Stony Brook University found that talking on a cellphone or texting while walking reduces your walking speed and makes it difficult to walk in a straight line.

Their preliminary research consisted of 33 men and women in their 20’s and tested them when they were texting and talking on the cellphone and vice versa.  Results showed that their walking speeds were 33 percent slower while texting and 16 percent slower while talking on the cellphone. Also, those who texted showed that there was a 61 percent increase in side-to-side deviation while walking. This added to the total travel distance increasing their walking time to their destination.

This study is used to help physical therapy patients improve their walking  in their early recovery process.
