Mammal microbiome

Giant pandas are not an evolutionary cul-de-sac: Evidence from multidisciplinary research
Fuwen Wei – Molecular Biology and Evolution

“The latest and most advanced research shows that giant pandas are successful animals highly adapted to a specialized bamboo diet via morphological, ecological and genetic adaptations and co-adaptation of gut microbiota.”

Plant microbiome

Multi-symbiotic systems: functional implications of the coexistence of grass–endophyte and legume–rhizobia symbioses – Pablo A. García Parisi – Oikos

“After five months, we quantified the number of nodules in Trifolium roots, shoot biomass of both plant species, and the contribution of atmospheric nitrogen fixation vs. soil nitrogen uptake to above ground nitrogen in each plant species. “

Microbes in the news

Young companies, big ideas – The 2014 edition of the CNN 10: Startups – CNN

“Her doubts were assuaged when supporters donated $350,000 to help launch her startup, uBiome. Now, two years later, uBiome is exploring an emerging field of human biology while giving users a glimpse into how their bodies work.”

No women, unfortunately! And they did not accept my application to be a judge either. MO BIO Laboratories, Inc. announces Microbiome Awards winners – PR NewsWire

“MO BIO Laboratories, Inc. is proud to announce the winners of the MO BIO Microbiome Awards, which provide young, extraordinary scientists with funding and recognition to carry out scientific work in the field of microbiome research.”

Super-bacteria are growing in space … and we’re the ones breeding them – Meera Senthilingam – CNN

“You might think of space as a germ-free environment, but microbes can be carried to space inside human gut flora as well as in food and water and once up there, can be expelled by humans in their breath.”

There’s a simple way to stop the spread of antibiotic-resistant bacteria – Melinda Mary Pettigrew – Washington Post

“The issue boils down to this: we use too many antibiotics. Studies show that up to half of all antibiotics are prescribed unnecessarily.”

Across Indian zoos, rat pee spreading bacteria, killing big cats: Scientists – Priyangi Agarwal – The Times of India

“The leptospirosis bacteria, found in rodent urine, makes its way into blood samples of zoo animals and causes higher morbidity and mortality, scientists at the Indian Veterinary Research Institute (IVRI) in Bareilly have found. “

Brazil releases ‘good’ mosquitoes to fight dengue fever – BBC

“Brazilian researchers in Rio de Janeiro have released thousands of mosquitoes infected with bacteria that suppress dengue fever. The hope is they will multiply, breed and become the majority of mosquitoes, thus reducing cases of the disease.“

Science, Publishing, and Career

Young, Brilliant and Underfunded – Andy Harris – New York Times

“The bulk of that money goes to researchers who are in many cases esteemed in their fields — but also, in many cases, beyond the age when most scientists make their most important contributions to their fields.”

Why women leave tech: It’s the culture, not because ‘math is hard’ – Kieran Snyder – Fortune

“Stories from 716 women who left tech show that the industry’s culture is the primary culprit, not any issues related to science education.”

Bik’s Picks

Is this the end of autumn as we know it? – Stephanie Pappas – BBC Earth

“The study of the basic triggers of autumnal leaf changes, never mind the impact of climate change on these, is still in its infancy in part because scientists have traditionally focused their attentions on the seasonal changes in March and April than those later in the year.”

The Incredible Rubber Glove – Olga Khazan – The Atlantic

“Basic protective gear was revolutionary for 19th-century medicine, and health workers trying to stop Ebola are recognizing its importance all over again.”

This Is Why Your Voice Sounds So Frickin’ Weird To You – Macrina Cooper-White – The Huffington Post
