Prompt, appropriate medical care for dislocated shoulder injuries
01/12/2014
|
CIENCIA ON LINE
Prompt and appropriate treatment of a dislocated shoulder -- when the head of the upper arm bone is completely knocked out of the shoulder socket -- can minimize risk for future dislocations as well as the effects of related bone, muscle and nerve injuries, according to a literature review....
Restrooms: Not as unhealthy as you might think
01/12/2014

New research involving rats suggests that if you were born at a low birth weight, supplemental co-enzyme Q may lower your risk for heart disease. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/i...
How lungs protect themselves from infection
01/12/2014
|
CIENCIA ON LINE
Scientists have taken an important step toward a new class of antibiotics aimed at stopping lung infections. They found that a protein found in large airways, called 'SPLUNC1,' binds to lipids critical to defending against bacterial and viral infections, as well as keeping lung tissue flexible...
Plant used in traditonal Chinese medicine may treat metabolic diseases and obesity
01/12/2014
|
CIENCIA ON LINE
New research shows that a component found in in the plant, Glycyrrhiza uralensis, may inhibit the development of metabolic disorders by stopping the activation of NLRP3, a protein involved in the disease process. Specifically, the researchers identified isoliquiritigenin as having the ability to...
Revolutionizing genome engineering
01/12/2014
|
CIENCIA ON LINE
Genome engineering with the RNA-guided CRISPR-Cas9 system in animals and plants is changing biology. It is easier to use and more efficient than other genetic engineering tools, thus it is already being applied in laboratories all over the world just a few years after its discovery. This rapid...
Duality in the human genome
01/12/2014
|
CIENCIA ON LINE
Human genomes are extraordinarily individual -- a challenge for personalized medicine. Results of a new study show that most genes can occur in many different forms within a population: On average, about 250 different forms of each gene exist. The researchers found around four million different...

Haematologists have developed a new active substance that effectively combats the most aggressive forms of Philadelphia chromosome-positive leukemia. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/O...
Emergence of modern sea ice in Arctic Ocean, 2.6 million years ago
28/11/2014
|
CIENCIA ON LINE
The extent of sea ice cover in Arctic was much less than it is today between four and five million years ago. The maximum winter extent did not reaching its current location until around 2.6 million years ago. "We have not seen an ice free period in the Arctic Ocean for 2,6 million years....
New material makes water and oil roll off
28/11/2014
|
CIENCIA ON LINE
Car finish, to which no dirt particles adhere, house fronts, from which graffiti paints roll off, and shoes that remain clean on muddy paths – the material “fluoropore” might make all this possible. Both water and oil droplets roll off this new class of highly fluorinated super-repellent...
Love at first smell: Can birds choose mates by their odors?
28/11/2014
|
CIENCIA ON LINE
Mate choice is often the most important decision in the lives of humans and animals. Scientists have found the first evidence that birds may choose their mate through odor. The researchers compared the preen gland chemicals of black-legged kittiwakes with genes that play a role in immunity....
Single-atom gold catalysts may offer path to low-cost production of fuel and chemicals
28/11/2014
|
CIENCIA ON LINE
New catalysts designed and investigated by engineering researchers have potential to greatly reduce processing costs in future fuels like hydrogen. The catalysts are composed of a unique structure of single gold atoms bound by oxygen to sodium or potassium atoms, supported on non-reactive silica...
Fragile X study offers hope of new autism treatment
27/11/2014
|
CIENCIA ON LINE
People affected by a common inherited form of autism could be helped by a drug that is being tested as a treatment for cancer, according to researchers. Fragile X Syndrome is the most common genetic cause of autism spectrum disorders. It affects around 1 in 4,000 boys and 1 in 6,000 girls....
Mindfulness treatment as effective as CBT for depression, anxiety
27/11/2014
|
CIENCIA ON LINE
Group mindfulness treatment is as effective as individual cognitive behavioral therapy (CBT) in patients with depression and anxiety, according to a new study. This is the first randomized study to compare group mindfulness treatment and individual cognitive behavioral therapy in patients with...
Ancient dental plaque: A 'Whey' into our milk drinking past?
27/11/2014
|
CIENCIA ON LINE
We drink milk because it is good for us, but we rarely stop to think "Why?" Archaeologists and geneticists have been puzzling this question since it was revealed that the mutations which enable adults to drink milk are under the strongest selection of any in the human genome. Fuente :...
New research supporting stroke rehabilitation
27/11/2014
|
CIENCIA ON LINE
New research could help improve stroke patients' rehabilitation, experts say. The research may provide useful applications for the care of stroke patients who have restricted use of their upper limbs. If stroke patients practice the techniques recommended by the study, it could potentially help...
Significantly increased risk of stillbirth in males, study shows
27/11/2014
|
CIENCIA ON LINE
Boys are more likely to be stillborn than girls, a large-scale study has found. The study reviewed more than 30 million births globally, and found that the risk of stillbirth is about ten percent higher in boys. This equates to a loss of around 100,000 additional male babies per year. Fuente :...
Matched 'hybrid' systems may hold key to wider use of renewable energy
26/11/2014
|
CIENCIA ON LINE
The use of renewable energy in the United States could take a significant leap forward with improved storage technologies or more efforts to 'match' different forms of alternative energy systems that provide an overall more steady flow of electricity, researchers say in a new report. Fuente :...
Post-medieval Polish buried as potential 'vampires' were likely local
26/11/2014
|
CIENCIA ON LINE
Potential 'vampires' buried in northwestern Poland with sickles and rocks across their bodies were likely local and not immigrants to the region. In northwestern Poland, apotropaic funerary rites--a traditional practice intended to prevent evil--occurred throughout the 17th-18th c. AD. Fuente :...
