Submission + - Platelet-like nanoparticles that can do more than clot blood (ucsb.edu)

Submitted by Chipmunk100
Chipmunk100 writes: UC Santa Barbara researchers have turned to the human body’s own mechanisms for inspiration in dealing with the necessary and complicated process of coagulation. By creating nanoparticles that mimic the shape, flexibility and surface biology of the body’s own platelets, they are able to accelerate natural healing processes while opening the door to therapies and treatments that can be customized to specific patient needs.

Submission + - Brain to Brain communication over the internet (sciguru.org)

Submitted by Chipmunk100
Chipmunk100 writes: Imagine if we could transfer complicated knowledge from the brain of a teacher to a student without having to find the right words? A research article was recently published in PloS ONE on the first safe and non-invasive method of decoding intentions from a human sender and transferring them to a human receiver over the internet. Over the course of three months, three pairs of participants completed brain-to-brain interface experiments. Communication between sender and receiver were tested by their ability to collaborate in the video game task of firing a cannon to destroy a rocket before it reaches the city, while sitting in different buildings half a mile apart. Results varied between participant pairs which were successful 83.3%, 25.0% and 37.5% of the time.

How do these particles avoid gut enzymes, once in the blood how do these particles avoid phagocytosis by macrophages, how can you expect that magnetic dragging of a number of these particles will not be deleterious, for example some of these got into cellular organelles being forcefully pulled out through their membranes etc. Either it is crazy or there is something ingenious about it.

Submission + - Location of spilled oil from 2010 Deepwater Horizon event found (ucsb.edu)

Submitted by Chipmunk100
Chipmunk100 writes: A study published in the journal Proceedings of the National Academy of Sciences claims to have identified the location of two million barrels of submerged oil thought to be trapped in the deep ocean following the 2010 Deepwater Horizon spill. By analyzing data from more than 3,000 samples collected at 534 locations over 12 expeditions, they identified a 1,250-square-mile patch of the deep sea floor upon which 2 to 16 percent of the discharged oil was deposited. The fallout of oil to the sea floor created thin deposits most intensive to the southwest of the Macondo well. The oil was most concentrated within the top half inch of the sea floor and was patchy even at the scale of a few feet.

Submission + - Green house gases or the ocean important in climate change (rutgers.edu)

Submitted by Chipmunk100
Chipmunk100 writes: Most of the concerns about climate change have focused on the amount of greenhouse gases that have been released into the atmosphere. Researchers have found that circulation of the ocean plays an equally important role in regulating the earth’s climate. The study results were published the journal Science (pay wall). “Our study suggests that changes in the storage of heat in the deep ocean could be as important to climate change as other hypotheses – tectonic activity or a drop in the carbon dioxide level – and likely led to one of the major climate transitions of the past 30 million years," said one of the authors.

Submission + - Glaciers in the Karakoram mountains do not melt - reason found (princeton.edu) 2

Submitted by Chipmunk100
Chipmunk100 writes: In a phenomenon known as the "Karakoram anomaly," glaciers in the Karakoram mountains, a range within the Himalayas, have remained stable and even increased in mass while many glaciers nearby — and worldwide — have receded during the past 150 years, particularly in recent decades. Researchers report in the journal Nature Geoscience that the ice is sustained by a unique and localized seasonal pattern that keeps the mountain range relatively cold and dry during the summer.

Submission + - Five things the CDC got it wrong on Ebola (cnn.com)

Submitted by Chipmunk100
Chipmunk100 writes: According to CNN, the following CDC might have made a mistake on the five most important aspects in Ebola care
1. The CDC is telling possible Ebola patients to "call a doctor."
How much do you know about Ebola? When passengers arrive in the United States from Liberia, Sierra Leone or Guinea, they're handed a flier instructing them to "call a doctor" if they feel ill.
2. The CDC director says any hospital can care for Ebola patients. "Essentially any hospital in the country can safely take care of Ebola. You don't need a special hospital to do it," Dr. Thomas Frieden said Sunday at a press conference.
3. The CDC didn't encourage the "buddy system" for doctors and nurses.
4. CDC didn't encourage doctors to develop Ebola treatment guidelines.
Taking care of Ebola patients is tricky, because certain procedures might put doctors and nurses in contact with the patient's infectious bodily fluids.
5. The CDC put too much trust in protective gear.

Submission + - "Love Hormone" Oxytocin Regulates Sociosexual Behavior in Female Mice (sciguru.org)

Submitted by Chipmunk100
Chipmunk100 writes: In a research article in the journal Cell scientists report that there is a subset of neurons that are vital in social interest of female mice for males during estrus, the sexually receptive phase of their cycle. They say that these neurons are responsive to oxytocin. The level of oxytocin rise when we hug or kiss a loved one.

Submission + - WhatsApp's next version to include VoIP calls and recording (geektime.com)

Submitted by Anonymous Coward
An anonymous reader writes: Apps like Viber, Skype, Tango and Google Hangout already support VoIP, which allows you to make voice calls over a broadband connection. Beyond WhatsApp’s huge pool of over 600 million active users, which will undoubtedly disrupt cell service providers’ payment model, what is even more intriguing is the VoIP recording feature. With the exception of third-party add-ons available for Skype, no other VoIP app includes this feature.

Submission + - Second Ebola case in US. (kxan.com) 1

Submitted by Anonymous Coward
An anonymous reader writes: Well, looks like the number does double every three weeks or so. A healthcare worker in Texas has apparently tested positive for the disease. (The Guardian is also carrying the story, http://www.theguardian.com/us-...) The explanation for how this happened is going to be interesting too. The nurse in Spain who got it is said to have failed to follow best practices for glove removal, and touched a part of the contaminated exterior of her protective equipment with her skin.

Was this something similar, or is it just possibly, maybe airborne? Since it's in body fluids including saliva in a contagious individual who may be sneezing, coughing, or just talking... (people spit when they talk whether or not anyone realizes it,) and moisture in breath comes from secretions inside the lungs, one wonders how it could NOT be airborne... but the guys in the white coats say not to worry, so I, obligingly, am not worried.

I have however, added to my calendar my predictions for infection rates. By November 1st, we'll have about 4 diagnosed cases... and about 2 dozen before Christmas. So glad we have top notch care here.

Submission + - Sexual conflict over mating impacts the parental care behaviour - a beetle study (exeter.ac.uk)

Submitted by Chipmunk100
Chipmunk100 writes: Beetles have surprisingly complex parental care, similar in form to that provided by birds such as robins or blackbirds, with offspring begging to be fed by touching parents, who respond by regurgitating partially digested food. Researchers at the University of Exeter have found that sexual conflict over mating impacts the parental care behaviour and reproductive productivity of burying beetles.
