Differences between “marathon mice” and “couch potato mice” reveal key to muscle fitness
by Heather Buschman, Ph.D. in Beaker
Sanford-Burnham researchers identify microRNAs as the missing link between the two defining features of muscle fitness—fuel-burning and fiber-type switching—providing a potential new target for interventions that boost fitness in people with chronic illness or injury.... Read more »

Dual Color Semiconductor Device Opens Way to Cheaper Lighting
by dailyfusion in The Daily Fusion
A group of scientists from the Arizona State University have developed a semiconductor device that is capable of emitting two distinct colors simultaneously. An ability to emit light in a wide spectrum range from a single monolithic structure could potentially become a basis for a cheaper and more efficient lighting technology.... Read more »

Does experience matter – Part II
by Rogue Medic in Rogue Medic
In spite of the evidence to the contrary and a lack of rationality in the claim, we continue to be told that increasing the number of people with a title, such as paramedic, will result in better care.
Here is more evidence that dividing the skills among more people leads to less skilled care.
The authors begin by referring to other studies that demonstrate the high failure rate of doctors performing procedures on children.
How is that relevant to EMS? We have a low frequency of use of ........ Read more »

Fluorescent Dye Increases Solar Cells’ Efficiency
by dailyfusion in The Daily Fusion
Scientists at Yale think that for some solar cells the future may be fluorescent. While many may believe that the purpose of a solar cell is to absorb light, not to emit it (fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation), it turns out that the addition of a fluorescent organic dye to the cell layer improves the ability of a promising type of solar cell to absorb light and convert it into electrical power....

Microbial Misadventures: Anthrax, Hippies & Drum Circles
by Rebecca Kreston in BODY HORRORS
When you think of drum circles taking place in the United States, visions of hippies, Birkenstocks and the vibrant green lawns of private colleges may appear. The bacteria Bacillus anthracis, or anthrax, does not often materialize alongside the skunky mix of patchouli and ganja hovering above the crowd in one’s visions of (ar)rhythmic drumming events.

Plants may communicate through some mysterious signals (possibly sound waves)
by Usman Paracha in SayPeople
Main Point:
Researchers have reported that a good neighborhood is important for the better growth of the plants as they could talk with each other possibly through sound waves in addition to other mechanisms.
Published in:
BMC Ecology
Study Further:
It was already found that plants could communicate with each other through shade, aromatic chemicals, and physical touch that is important in better growth, and protection from diseases and invaders such as bees.
Now researchers hav........ Read more »

“Can you hear me now?” The new record holder for hearing

This is our new winner, ladies and gentlemen.
This unassuming moth is a greater wax moth (Galleria mellonella). Don’t let its drab appearance fool you, friends. This is a record-setting animal, with one of the most extreme sensory systems yet found. Its speciality? Hearing.
When you listen to anything, there are two main properties inherent in the sound: loudness and tone. The volume is determined by the size of sound waves; the tone is set by the frequency of sound waves. Humans hear t........ Read more »

Thanks Mom!

Like Mother, like baby! Photo from freedigitalphotos.net.Moms give us so much more than we ever give them credit for. Biologically speaking, we all have a mom and a dad (unless you’re a flatworm or some other species that can reproduce without sex) that provide us with one of each chromosome type (our chromosomes contain our genes, commonly thought of as our “biological blueprints”).

On Puppies, Pet Stores, and Behaviour Problems

If you buy a puppy from a pet store, could you be getting more than you bargained for? It has long been thought that puppies from pet shops might have behavioural problems. A new study by Franklin D.

These are large establishments that breed ........ Read more »

It's An Airtight Case
by Mark Lasbury in As Many Exceptions As Rules
Humans are relatively weak when it comes to oxygen utilization. We can’t go very long without breathing, while other animals can make much better use of the oxygen they take in and can therefore go longer between breaths. The reasons for these differences are starting to be understood. These include special proteins in the brain to prevent hypoxic damage, and alternate gas exchange pathways, like plastron respiration in ticks. Mycobacterium tuberculosis can survive 50 years in hypoxic cond........ Read more »

Scientists have named a new species of bone-headed dinosaur (pachycephalosaur) from Alberta, Canada. Acrotholus audeti (Ack-RHO-tho-LUS) was identified from both recently discovered and historically collected fossils. Approximately six feet long and weighing about 40 kgs in life, the newly identified plant-eating dinosaur represents the oldest bone-headed dinosaur in North America, and possibly the world. Research describing the new species is published May 7, 2013 in the journal Nature Communic........ Read more »
