How (apparently) identical animals can be completely different species
Logically speaking, you would think that animals who appeared to be the same—even if they were found in different parts of the world—would belong to the same species, and that they would share the same genome. However, our recent study has found.....»»
Pathogenic system found on Providencia rustigianii has virulence gene akin to Salmonella"s

Microbiome studies in humans and zoo animals pave the way for new drug development
Microorganisms do not just colonize the body of mammals during infections. Billions of microbes can be found on and in healthy humans and animals at any given time, communicating with each other via chemical signals and thus influencing their health......»»
Aquaculture could harm animal welfare or protect it, depending on what species the farms raise
The global aquaculture industry has tripled in size since the year 2000, with producers raising a mind-boggling diversity of species, from seaweeds and clams to carp, salmon and cuttlefish. Many of these creatures are undomesticated and lead complex.....»»
Humans have near-equal numbers of male and female babies, unlike many other animals—a new genetic study looks for clues
We know that boys and girls are produced in much the same frequency. But how—and why—is this 1:1 ratio achieved?.....»»
Human Origins Look Ever More Tangled with Gene and Fossil Discoveries
Fossil and gene discoveries paint an ever-more-intertwined history of humans combining with vanished species like Neandertals.....»»
Genome sequencing could unlock answers to yellow jacket behavior
The most recognizable yellow jacket at Georgia Tech is made of fabric and foam, but Professor Mike Goodisman and a team of researchers revealed a far more complex cellular structure by successfully sequencing the genome of two local species of yellow.....»»

Resilience over reliance: Preparing for IT failures in an unpredictable digital world
No IT system — no matter how advanced – is completely immune to failure. The promise of a digital ring of steel may sound attractive, but can it protect you against hardware malfunctions? Software bugs? Unexpected environmental conditions? Cybers.....»»
Ship-mounted camera systems help increase protections for marine mammals
Vessel strikes and entanglement are some of the leading causes of injury and death to marine animals such as whales. Increasingly urbanized waterways, warming oceans, changes in prey distribution—and in some cases, increasing species populations—.....»»
To keep Miami"s tree canopy resilient, tropical species may be the best option for planting
In Miami—a place known for one of the most diverse tree canopies in the world—nearly half of the native trees may struggle to survive in the coming decades, a new University of Miami study indicates......»»
New venomous reptile species from the Late Triassic unearthed in Arizona
A new species of small, venomous reptile, Microzemiotes sonselaensis, has been discovered in the Late Triassic Chinle Formation in northeastern Arizona. The findings, recently published in PeerJ, shed new light on the evolution of venomous feeding st.....»»
From Northern Germany to Italy in five days: Tiny transmitters provide insights into precise migration routes of bats
Some bat species are among the world champions of seasonal migration in the animal kingdom. Leisler's bat, for example, which weighs between 12 and 22 grams, flies from central or Eastern Europe to the Mediterranean every late summer—and back in sp.....»»
Global study shows causes for the dominance of woody plants in drylands
Precipitation, temperature, and grazing have the greatest influence on whether woody or herbaceous species grow in dryland areas. This has been shown by a large global study that includes Potsdam researchers......»»
Airborne DNA tech transforms endangered wildlife monitoring
University of Queensland researchers have created new tools that could change how conservation experts monitor and protect some of Australia's most endangered species......»»
A Hong Kong zoo seeks answers after 9 monkeys die in 2 days

Modern mass extinction in an Ecuadorean cloud forest found to be a mirage
One of the most notorious mass extinction events in modern times occurred on a hilltop in coastal Ecuador in the 1980s. Ninety species of plants known from nowhere else on Earth—many of them new to science and not yet given a name—went extinct wh.....»»
Seven new frog species discovered in Madagascar
An international team of researchers have discovered seven new species of tree frogs that make otherworldly calls in the rainforests of Madagascar. Their strange, high-pitched whistling calls sound more like sound effects from the sci-fi series "Star.....»»
