 Antimatter: Have you ever heard about Antimatter? You may have probably not heard of it much. Antimatter is basically a mirror image of existing matter and it is very difficult to make. This can be created by physicists at the world’s largest particle accelerator called the Large Hadron Collider, near Geneva, Switzerland. This material is scarcely available, only about a billionth of a gram can be made per year. It is so rare that even its potential uses are still largely not known. One of its explored uses is that antimatter shows some possibility of practical application in treating cancer. Not only can it be used as medicine, it can also be possibly used to fuel spaceships to the planets in future. Its price is nearly $62.5 trillion/gram.

 Californium 252: Californium is a radioactive transuranic element with its atomic number as 98 is a man-made element. It was discovered in 1950. It was created by scientists by bombarding the chemical element curium with alpha particles which resulted into a radioactive material. There are almost ten known versions, or isotopes of this material that exist. Few of its uses include treating certain forms of cancer and detecting gold and silver in ore or oil at the bottom of a well. It is true that californium is artificially made on Earth, but it is also said that certain stars that explode as super-novae may produce californium in space too. The actual price of californium is $27 million/gram.

Fatal toxins found in ‘edible’ wild mushrooms
A wild mushroom eaten by foraging enthusiasts across Europe has been found to contain dangerous and potentially lethal toxins. Chinese scientists believe they have identified the mushroom toxins that cause rhabdomyolysis – a sometimes fatal disease that can irreparably damages the kidneys – that was first reported 15 years ago in France. However, the toxins were not isolated from the mushroom Tricholoma equestre that was thought to be responsible for the deaths, but from Tricholoma terreum, its close relative, highlighting the complexity of fungus toxicology. These scientists are recommending that people who forage for mushrooms avoid eating both of these species.
The two new compounds are of medium toxicity, so it is possible that they work together, perhaps with other unknown mushroom toxins, in a cumulative way to cause lethal rhabdomyolysis.
A person would have to eat a portion of T. terreum every day for several days before the dose would be deadly. He says that it is fortunate that T. terreum, prized for its flavour, is only eaten in small quantities or there might have been more fatalities.
A combination of three types of mushroom toxins may have been responsible for more than 200 deaths in China.

Magnetic Levitation Lifts Impurities from Pharmaceuticals
Separating therapeutic molecules from nonhelpful "twins" is tough, but a new magnetic method that can pull them apart may be the answer

A study in Neurology  suggests that eating a lot of sugar or other carbohydrates can be hazardous to both brain structure and function.

Findings indicate that even in the absence of diabetes or glucose intolerance, higher blood sugar may harm the brain and disrupt memory function.

How Data Beats Intuition at Making Selection Decisions
A recent meta-analysis by Kuncel, Klieger, Connelly and Ones found that, across multiple criteria in work and academic settings, when people combined hard data with their judgments, and those of others, their predictions were always less valid, and less predictive of real outcomes, than those generated by hard data alone.

“To know that we know what we know, and that we do not know what we do not know, that is true knowledge,” Confucius once said. Algorithms using objective data lead to much greater accuracy in predicting widely valued outcomes such as job and academic performance. A true expert is someone who knows what they do not know—namely, that our intuition can fail us.

Microwave-based stroke diagnosis making global pre-hospital thrombolytic treatment possible
A helmet placed on the head of a stroke victim sends low-intensity microwaves through the brain to quickly determine whether a blockage or hemorrhage is taking place, making faster treatment possible.
When a person suffers a stroke quick treatment is crucial. But there are two very different kinds of strokes: some result from blood clots that block circulation within the brain, others are caused by ruptured vessels that spill blood into surrounding tissue. The use of clot-busting drugs when a hemorrhage is happening can cause additional injury or death. So doctors lose precious time waiting for stroke victims to get MRIs or CAT scans before they start treatment.

But soon EMT’s might be able to quickly tell whether patients have a blockage or a bleed—by having them wear a high-tech helmet.

Researchers at Chalmers University of Technology in Gothenburg, Sweden developed the prototype helmet and tested it on 45 stroke patients.

The gadget covers the head with a patchwork of antennas. As each antenna beams low-intensity microwaves through the head in sequence, the other antennas detect how the waves scatter. Any pooling blood from a hemorrhage causes deflections easily spotted on an attached computer.

Classroom Decorations Can Distract Young Students
Five-year-olds in highly decorated classrooms were less able to hold their focus, spent more time off-task and had smaller learning gains than kids in bare rooms
''Visual Environment, Attention Allocation, and Learning in Young Children
When Too Much of a Good Thing May Be Bad''

A large body of evidence supports the importance of focused attention for encoding and task performance. Yet young children with immature regulation of focused attention are often placed in elementary-school classrooms containing many displays that are not relevant to ongoing instruction. We investigated whether such displays can affect children’s ability to maintain focused attention during instruction and to learn the lesson content. We placed kindergarten children in a laboratory classroom for six introductory science lessons, and we experimentally manipulated the visual environment in the classroom. Children were more distracted by the visual environment, spent more time off task, and demonstrated smaller learning gains when the walls were highly decorated than when the decorations were removed.
