Yes, that is right. Your beard is a place for millions of bacteria. And some of them can be used by scientists to produce newer antibiotics.
Research conducted in London has determined that some of the bacteria growing in men’s beards have antibiotic properties. The discovery is important at a time when the overuse of man-made antibiotics is making pathogenic bacteria strains increasingly resistant to treatment.

Overuse of antibiotics in children can lead to drug-resistant infections, as well as leave kids at high risk of a future infection that is difficult to treat, the researchers warned.
“International and national guidelines clearly state that antibiotics should not be given for a deterioration in asthma symptoms, because this is rarely associated with a bacterial infection,” Esme Baan from the Erasmus University, in the Netherlands.
“Inappropriate use of antibiotics can be bad for individual patients and the entire population, and makes it harder to control the spread of untreatable infections.”
The researchers found that children with asthma were approximately 1.6 times more likely to be prescribed antibiotics, compared to children who do not have asthma.
“Antibiotics should only be given when there is clear evidence of a bacterial infection such as for pneumonia,” Baan said.
“However, we saw that, in children with asthma, most of the antibiotic prescriptions in children were intended for asthma exacerbations or bronchitis, which are often caused by a virus rather than bacteria.”
For the study, presented at the European Respiratory Society International Congress 2017 in Italy, the team included 1.5 million children from the UK, including around 150,000 with asthma, and a further 375,000 from The Netherlands, including around 30,000 with asthma.
Antibiotic prescription rates were almost two-fold higher in the UK overall. In both countries, amoxicillin was the most commonly used antibiotic. (IANS)
Bacterial resistance to antibiotics causes more about 23,000 deaths annually.
Breast milk helps newborns fight bacterial infections
Researchers discover natural sugars that can reduce human dependence on antibiotics
Washington DC, August 22, 2017 : Newborns and infants are highly susceptible to bacterial infections and diseases. In the face of medical challenges, young mothers tend to look for remedies that cater to the problem with the least possible side-effects. In a latest study by a Washington DC University, it has been revealed that the mother’s milk consists of a unique blend of fats, proteins, and sugars that help protect babies against bacterial infection.
As per the World Health Organization (WHO) guidelines, mother’s milk is supposed to be the only nutrition for a newborn for the first six months.
Breastfeeding is one of the key phases to nurture a newborn. Combined with antibodies and nutrients, the practice is not only beneficial to the baby but for the mothers as well.
Breast milk addresses a multitude of problems and diseases in children,
Lowers risk of allergies and asthma
Reduces respiratory illnesses and chances of diarrhea.
Apart from these, researches have not revealed that it also helps babies fight against bacterial infections.
An interdisciplinary team of doctors and chemists at the Vanderbilt University have discovered that carbohydrates in a mother’s milk possess a complex blend of antibacterial properties. Additionally, the research also revealed that apart from their own qualities, the presence of these carbohydrates also enhances the efficacy of antibacterial proteins present in the milk.
Calling it an example of a comprehensive antimicrobial action by the carbohydrates present in the mother’s milk, according to Steven Townsend, the director of the study, “One of the remarkable properties of these compounds is that they are clearly non-toxic, unlike most antibiotics”, as per a report by ANI.
According to the data by Center for Disease Control and Prevention, bacterial resistance to antibiotics causes about 23,000 deaths annually.
Additionally researchers asserted that pregnant women are the most common hosts to group B strep bacteria, which cause severe infections in newborns. These infections often lead to pneumonia or sepsis, and in extreme cases death due to the absence of properly developed defense mechanisms in newborns.
However, group B strep bacteria rarely infect babies.
This motivated the researches to undertake a research to address the growing number of deaths and to probe whether the mother’s milk contains specific protective compounds that fight these bacteria in babies.
Previously, it was believed by biochemists that proteins are the most important followed by carbohydrates. “Far less is known about the function of sugars, and as a trained glycoprotein chemist, I wanted to explore their role,” asserted Townsend.
For the research, the carbohydrate in human milk, also known as oligosaccharides, was collected from different donor samples. The samples were then summarized with a mass spectrometry technique that is used to identify large biomolecules. The obtained compound was then added to strep cultures which were then observed using a microscope.
The study showed that the sugars found in breast milk in such cases can act as anti-biofilms agents. To put it simply, the researchers observed that the sugars not only sensitized the target bacteria but also killed them. Some of the oligosaccharides directly fought the infecting bacteria. Additionally the carbohydrate compounds also broke down the biofilms that the bacteria form to protect themselves.
It ha been revealed that these powerful sugars can potentially become part of an antibacterial treatment for adults and infants alike, thus reducing our dependence on artificially produced antibiotics.
This study has been published and is now a part of the ACS Infectious Diseases journal.

The latest research suggests that the modern apples originated from Kazakhstan
The study was carried out by researchers from Boyce Thompson Institute in the United States
It was the genetic exchange from traders who used the Silk Road that the modern apples emerged in Kazakhstan
US, August 17, 2017: A new study suggests that the modern apples that are so crisp, yet so juicy, actually originated from Kazakhstan 10,000 years ago.
The study by researchers at Boyce Thompson Institute (BTI) in the US reveal that during the back and forth traveling by traders on the Silk Road, the genetic exchange occurred that led to the emergence of modern day apples in Kazakhstan’s mountainous regions. Malus Domestica is the scientific name for our modern domesticated apples.
The Silk Road connected the East to the West. Hence, it led to an exposure of knowledge and ideas. Researchers hypothesize that this exchange of ideas resulted in the birth of the tasty Malus Domestica.
Lead Author of the study and Professor at Boyce Thompson Institute, Zhangjun Fei, explains his team’s study which is published in the journal Nature Communications.
To carry out the study, the team of researchers sequenced 117 different apples and compared their genomes. These included the wild species extracted from Europe, North America, Central and East Asia.
The birth of the modern apples ultimately led to 7,500 varieties of the fruit. Interestingly, the quality of the fruit changed as from region to region as it first traveled from the East to the West. When the apples returned to go back to the west, the dropped seeds on the way helped the growth of trees in wild places.
M Sylvestris was dominant in the Apple’s growth. It’s ancestor, M Sieversii is found predominantly in Kazakhstan.
Our modern day apples have well-balanced sugar and higher organic acid contents. Hence, it is no wonder now that Apple is one of the favorite fruits for many people.
