Antibiotics improve growth in children at risk of undernourishment in low and middle income countries, according to a literature review in the British Medical Journal.

Malnutrition in early childhood, reflected in poor growth, is the cause of nearly half of all mortality worldwide in children less than five years old. Antibiotics are currently recommended by the World Health Organization (WHO) for severely malnourished children, and those infected or exposed to HIV, to reduce mortality. But while antibiotics have been linked to significant height and weight gains among children from undernourished populations in countries such as Guatemala, Malawi, Zambia, and Brazil, some studies have found no significant effect of antibiotics. 

Ménière's Disease is a rare condition affecting the inner ear.  It can cause tinnitus, hearing loss, vertigo attacks and a feeling of pressure deep within the ear and is a long term but non-fatal illness, making it low profile in scientific community.

But 160,000 sufferers in the UK are getting some help from the University of Exeter Medical School, which has been able to suggest what goes wrong in the body when people develop the disease, and provide an insight into factors that lead to its development.

The human protein Elafin plays a key role against the inflammatory reaction typical of Celiac disease and researchers have developed a probiotic bacterium able to deliver Elafin in the gut of mice.

Celiac disease is an auto-immune pathology that occurs in individuals genetically predisposed to gluten intolerance. Affected people do not harbor the enzymes required to degrade gluten during digestion and inflammatory reactions are induced by this abnormal digestion which can lead to the destruction of the gut barrier that is essential for nutrients absorption.
Researchers have have found that the repeated application of manure contaminated with antibiotics changes the composition of bacteria in the soil.

The focus of the investigation was on sulfadiazine (SDZ), a widely used antibiotic in animal husbandry which enters the soil via manure. The researchers report that repeated application of the antibiotic leads to a decrease in beneficial soil bacteria and at the same time an increase in bacteria that are harmful to humans.

After playing in every game for some 14 years in baseball, Lou Gehrig of the New York Yankees - "The Iron Horse" - took himself out of the lineup because his manager wouldn't. He had been dropping balls, unable to get to routine plays, hitting in the low .100s, shuffling rather than running.

A month later he was diagnosed with the disease that would become synonymous with his name. That he had been able to do any sports at all, much less Major League Baseball, with amyotrophic lateral sclerosis
- ALS - is startling to doctors and patients today. Two years later he was dead but today, as many as 30,000 Americans are living with it.

In unvaccinated hotbeds like California and New York, rich elites rely on 'herd immunity' to protect their children - poor families will get the vaccines and protect the rich ones. That's why in those states, easily preventable diseases have come roaring back, with dangerous consequences.

Developing nations should be a reminder to anti-science progressives about the risks they are inflicting on kids who can't get vaccines, and their own children as well. Nearly 4 million children under 5 die from vaccine-preventable diseases worldwide each year.

The code for every gene includes a message at the end of it that signals the translation machinery to stop but diseases like cystic fibrosis and Duchenne muscular dystrophy can result from mutations that insert this stop signal into the middle of an essential gene, causing the resulting protein to be truncated.

Some antibiotics cause the cell's translation machinery to ignore the stop codons and are therefore being explored as a potential therapy for these diseases. New research in Proceedings of the National Academy of Sciences finds that this approach could come with the price of triggering autoimmune disease.

West Nile virus is spread by infected mosquitoes and targets the central nervous system. It can be fatal disease and there is currently no cure or drug treatment. It has spread across the U.S., Canada, Latin America and the Caribbean. 

An international research group has developed a cost-effective therapeutic against West Nile virus and other pathogens. The therapeutics, known as monoclonal antibodies (MAbs) and their derivatives, were shown to neutralize and protect mice against a lethal dose challenge of West Nile virus - even as late as 4 days after the initial infection. 

A new type of single-dose vaccine comes in a nasal spray and doesn't require refrigeration.

The latest design and testing of these "nanovaccines" sets the stage to dramatically alter the public health landscape because it can get more people vaccinated around the world squash the looming threats of emerging and re-emerging diseases. 

Nature is always looking for new ways to stay ahead. To-date, resistance to pesticides has been recorded in more than 500 insects, 218 weeds, and 190 fungi that attack plants.

The recorded cases of resistance in insects, mites and other arthropods, which include resistance to multiple pesticides per species, more than doubled between 1990 and 2013, from 5,141 to 11,254.

How will a new glossary help? The authors of updated definitions in the Journal of Economic Entomology say a common vocabulary is needed because the current jumble of terms fosters confusion among scientists in academia, industry and government.
