Biochip for rapid detection of sepsis
The quick diagnosis and medical treatment can save lives, especially in cases such as sepsis. The faster and more directly recognize and treat medical sepsis, the more likely the patient will survive. With the help of a new biochip, physicians can analyze blood more quickly and easily.
Does the patient have septicemia? Today, to answer this question, the doctor takes a blood sample and sends it to a lab to analyze. This consumes valuable time that could cost the life of the patient. In the future, doctors will test blood in his office and get results in about twenty minutes.
Avalanches on Mars by the mere approach of meteorites
When a meteorite approaches the Red Planet’s dusty surface and begins to kick up dust, and can cause an avalanche even before cosmic rock impacting the surface. This is the amazing conclusion reached in a study at the University of Arizona.
The team of Kaylan Burleigh and H. Jay Melosh hoped that some of the dust grains visible on the slopes studied was caused by seismic shock during impact. For its surprise, all aims at that the shock wave in the air unchains often the avalanches, even before the collision against the surface be produced.
The X-ray laser creates world’s most powerful area of 2 million degrees
U.S. and European researchers have turned to powerful laser pulses a small piece of aluminum foil to get what is known as “hot dense matter”, solid plasma reached a temperature of about 2 million degrees. The whole process took place in just a trillionth of a second, as published this week in nature.
The experiments were carried out with a super X-ray laser pulses whose ultra fast are a billion times brighter than those achieved by any other of its kind so far. This is the Linac Coherent Light Source (LCLS) installed at SLAC National Accelerator Laboratory, a center operated by Stanford University in the U.S.
New technique for disinfecting rooms and insects
It has forged a disinfection system that can change the way of cleaning the rooms of the hospitals around the world, and is also capable of killing insects in hotels, homes and buildings in general.
The new method involves pumping a special mixture of ozone and hydrogen peroxide in the form of gas, into the room to be treated, in order to completely sterilize anything present in it, including the floor, walls, curtains, mattresses, chairs and other surfaces. It is much more effective in killing bacteria in a room that the traditional method of scrub.
The dangers of high blood pressure in middle age
An increase in blood pressure when a person is middle-aged, significantly increases your risk of heart attack or stroke at some point the rest of his life, according to new research. This study provides a new perspective on the importance of maintaining low blood pressure upon entering middle age, in order to prevent heart disease appear some time later.
The research found that men and women who developed hypertension being middle-aged or have already suffered, had a 30 percent increased risk of heart attack or stroke, compared with those who maintained their blood pressure low. Previous estimates of the risk that a person suffering from cardiovascular disease was based on a single measurement of blood pressure.
Relationship between social prejudices and fears ill
Many anthropologists suspect that social prejudices have their evolutionary roots in the instinct of survival, particularly in the trend that our distant ancestors had to avoid strangers, by ignoring them their health and fear they could be carriers of disease.
Research shows that even today when people feel vulnerable to disease, exhibit more prejudice against socially stigmatized groups. In a new study has delved into the issue.
Use unexpected for a line of cardiology research in neurology and microbiology
A diverse group of scientists, experts in cardiology, neurology, immunology, microbiology and chemistry, is being organized to study potential drugs that have shown promise in treating HIV-associated dementia, to explore its potential usefulness in the treatment of an equally worrying disease: heart failure.
In this case, the connection between head and heart behind a particular enzyme that scientists believe plays an important role in the development of that in the case of dementia and heart failure.
Robots with more autonomy and intelligence to explore the surface of Mars
An autonomous navigation system that allows a future rover have complete control of its own shares as it moves across the surface of Mars and explore the land, is being designed by scientists and engineers in the UK, France and Canada, Rutherford Appleton Laboratory (STFC) near Oxford in the UK.
The Seeker Project is a project of seven months to design a system of navigation that, as opposed to the previous systems, will permit to a robotic vehicle to be displaced by Mars of completely independent form, covering at least a kilometer to the day. The Seeker navigation system will allow better react to their environment and carry out experiments in more places.
The large scale use of solar energy is much cheaper than you think
The idea that the photovoltaic solar energy is still too expensive to make it viable to use it widely is a myth. So resounding shows Joshua Pearce, Professor in the Department of Mechanical Engineering and Materials Engineering at Queen’s University in Canada.
“Many analysts expect a higher cost for photovoltaic solar energy because these do not consider recent technological advances and price reductions”, argues the expert of that Canadian university. “The old models to determine the costs of solar PV are too conservative”.
Network reaches a speed of 186 gigabits per second
It has set a new world record for data transfer, a milestone that will help make possible the advent of next generation technology to high-speed networks.
An international team of researchers recently succeeded in transferring data in opposite directions at a combined rate of 186 gigabits per second (Gbps) across a network. This rate is equivalent to moving two billion gigabytes a day, fast enough to transfer in one day nearly 100,000 Blu-ray complete, i.e. each with a full movie and all its accessories.
