WE LOVE SCIENCE HERE BECAUSE IT IS A MANY SPLENDOURED THING

THIS IS A WAR ZONE WHERE SCIENCE FIGHTS WITH NONSENSE AND WINS

“The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.”

"Being a scientist is a state of mind, not a profession!"

"Knowledge is a Superpower but the irony is you cannot get enough of it with ever increasing data base unless you try to keep up with it constantly and in the right way!" The best education comes from learning from people who know what they are exactly talking about.

Science is this glorious adventure into the unknown, the opportunity to discover things that nobody knew before. And that’s just an experience that’s not to be missed. But it’s also a motivated effort to try to help humankind. And maybe that’s just by increasing human knowledge—because that’s a way to make us a nobler species.

If you are scientifically literate the world looks very different to you.

We do science and science communication not because they are easy but because they are difficult!

Comment by Dr. Krishna Kumari Challa on October 24, 2018 at 9:59am: Microplastics have been found in the human food chain as particles made of polypropylene (PP), polyethylene-terephthalate (PET) and others were detected in human stools, research presented recently at the 26th UEG Week in Vienna reveals.

Researchers from the Medical University of Vienna and the Environment Agency Austria monitored a group of participants from countries across the world, including Finland, Italy, Japan, the Netherlands, Poland, Russia, the UK and Austria. The results show that every single stool sample tested positive for the presence of microplastic and up to nine different plastic types were identified.

Microplastics are small particles of plastic less than 5mm and are used in various products for specific purposes; as well as being created unintentionally by the breaking down of larger pieces of plastic through weathering, degradation, wear and tear. Microplastic may impact human health via the GI tract where it could affect the tolerance and immune response of the gut by bioaccumulation or aiding transmission of toxic chemicals and pathogens.
The stools were tested at the Environment Agency Austria for 10 types of plastics following a newly developed analytical procedure. Up to nine different plastics, sized between 50 and 500 micrometres, were found, with polypropylene (PP) and polyethylene terephthalate (PET) being the most common. On average, the researchers found 20 microplastic particles per 10g of stool.

Comment by Dr. Krishna Kumari Challa on October 18, 2018 at 10:28am: Alarming news! Microplastics found in 90% of table salt around the world.

A paper published in the journal Environmental Science & Technology.

recently says those from Asian brands were especially high. In another indicator of the geographic density of plastic pollution, microplastics levels were highest in sea salt, followed by lake salt and then rock salt. The new study estimates that the average adult consumes approximately 2,000 microplastics per year through salt.

Comment by Dr. Krishna Kumari Challa on September 14, 2018 at 8:41am: New molecule with sneaky tactics to kill drug-resistant superbugs ...
A new molecule can kill deadly strains of common bacteria, such as Escherichia coli and Klebsiella pneumonia, that are resistant to most existing antibiotics. The drug works differently from currently available antibiotics, potentially making it harder for bacteria to develop resistance, researchers report September 12 in Nature.
Most antibiotics kill bacteria by weakening their cell wall or by preventing the production of certain proteins. But bacteria have, over time, evolved ways to circumvent these drugs.
The newly developed drug uses a different tactic. It inhibits a key enzyme in the cell membrane that helps the bacteria secrete proteins. That means that strategies that bacteria use to evade existing antibiotics won’t work here, giving the molecule an edge. When the enzyme is blocked, proteins build up in the cell membrane until the membrane bursts, ultimately killing the cell.
The molecule will need to go through additional testing and tweaking before it can be used in humans.

Comment by Dr. Krishna Kumari Challa on July 25, 2018 at 6:02am: Chemical additives in food for kids are highly harmful

The American Academy of Pediatrics is cautioning parents and pediatricians to avoid exposing children to eight chemicals found in food and in plastic packaging. The chemicals may be especially harmful to kids due to their small size, says the report published July 23 in Pediatrics. Pregnant women should also avoid the chemicals. And lower-income families who eat a lot of prepackaged foods could be at greater risk for exposure.

The chemicals include nitrates and nitrites, often added to processed meats as a preservative, as well as bisphenol A, or BPA, which is used to make durable plastics and has been linked to cancer, obesity and cardiovascular disease . Also listed are phthalates, which help make plastic flexible, and perfluoroalkyl chemicals, or PFCs, which are resistant to stains, grease and water. These and other compounds have also been associated with endocrine disruption, obesity and insulin resistance, when cells don’t respond properly to insulin leading to an overproduction of the hormone .

Some of these chemicals may also have neurocognitive effects, such as increased hyperactivity in children, says study coauthor Sheela Sathyanarayana, a physician and epidemiologist at the University of Washington in Seattle.

Scientists are unable to test the effects of these chemicals directly in humans, so evidence shows only that there is correlation, not causation, between exposure and disease.

To avoid these chemicals, the report suggests that parents buy fresh or frozen produce and skip processed meats packaged in plastic or food in metal cans, which can be lined with BPA. People should also avoid putting plastic containers in the dishwasher or microwave, the team says, where heat can draw chemicals out of plastic.

The researchers say that they hope the report prompts more strict regulation of these additives.

Comment by Dr. Krishna Kumari Challa on June 16, 2018 at 5:39am: Bacteria survive in NASA's clean rooms by eating cleaning products
Even NASA clean rooms -- the squeaky-clean places where the agency assembles its spacecraft -- have their own microbiomes, a common community of super-hardy species that somehow withstand the rigorous disinfection procedures. The microbiomes in the clean rooms are dominated by Acinetobacter bacteria, which are typically found in soil and water. Scientists have isolated strains from the surface of the Mars Odyssey orbiter, from the floors on which the Mars Phoenix lander was assembled, from the exterior of the International Space Station and even from the station's drinking water. Now, a team of scientists led by Rakesh Mogul from California State Polytechnic University at Pomona has discovered one of Acinetobacter's survival tricks: these microbes can eat the very cleaning products that are meant to banish them. "You can clean the rooms out and sterilize them, but microbes are still there," says Mogul. "To be a bit Jurassic Park about it: life will find a way."

Comment by Dr. Krishna Kumari Challa on June 11, 2018 at 9:57am: Bacteriophage link to parkinson's disease identified ...

In the first study of its kind, researchers from the New York-based Human Microbiology Institute have discovered the role certain bacteriophages may play in the onset of Parkinson's disease (PD). The research is presented at ASM Microbe, the annual meeting of the American Society for Microbiology, held from June 7th to June 11th in Atlanta, Georgia.

The researchers, led by George, Tetz, M.D., Ph.D., Human Microbiology Institute, showed that the abundance of lytic Lactococcus phages was higher in PD patients when compared to healthy individuals. This abundance led to a 10-fold reduction in neurotransmitter-producing Lactococcus, suggesting the possible role of phages in neurodegeneration. Comparative analysis of the bacterial component also revealed significant decreases in Streptococcus spp. and Lactobacillus spp. in PD.

Lactococcus are regulators of gut permeability and are enteric dopamine producers, which plays a primary role in PD. "The depletion of lactococcus due to high numbers of strictly lytic phages in PD patients might be associated with PD development and directly linked to dopamine decrease as well as the development of gastrointestinal symptoms of PD," said Dr. Tetz.

To explore bacterial and bacteriophage community compositions associated with PD, the researchers used shotgun metagenomics sequencing data of fecal microbiome from 32 patients with PD and 28 controls.

The results indicate that the decrease in Lactococci in the PD patients was due to the appearance of strictly lytic, virulent lactococcal phages belonging to the c2-like and 936 groups that are frequently isolated from dairy products. These results open a discussion on the role of environmental phages and phagobiota composition in health and disease.
