Having a hobby is healthy

HobbiesHobbies are often seen as something that person does just to do it. What many non-hobbyists don’t understand is that hobbies bring out the best in a person. You can experience great amounts of joy from participating in a hobby actively. Art is one of the major hobbies that people are part of, and photography being a large part of that as well.

Photography as a hobby is a fantastic way to see the world around you, and try new things. Photographers are often people who travel and are physically capable of immersing themselves into their hobby of photography. Landscape photographers are a good example, because many of them have to climb mountains, scale caves, and sail a boat, to get the fantastic photos that they can share with the world.

Having a hobby is healthy, especially when it involves hobbies that require movement and social interaction. Your body and mind gain so much from photography hobbies, including creativity, knowledge, and social contentment. Photography is one of the few hobbies that will allow you to learn everything about a person from one photograph.

Cocoa May Lower Blood Pressure

coffee-machineA new home remedy for lowering blood pressure may be to eat cocoa daily! Harvard professor Norman Hollenberg has found evidence that cocoa rich in flavanols, antioxidant compounds found in cocoa beans, improves blood flow which may help people fighting a range of diseases, including hypertension.

His discovery began as a study into the genetics of a small, isolated Caribbean Indian tribe in which hypertension was virtually nonexistent. He quickly found that their resistance was not genetic, as tribe members who had integrated themselves into other societies no longer had the same resistance to high blood pressure. Hollenberg decided to study the lifestyle of the Kuna tribe, “The most outstanding finding was the fact that most them consume cocoa as their major drink and do so every day,” according to Hollenberg, “Many Kuna, in that hot and humid climate, probably drink more than five cups per day.”

Is science ever wrong?

Science is a well-established way of testing ideas. Scientists have an idea, and then run an experiment to test it. Then they look at the result, to see if they correctly predicted what happened. In many fields of science, including medical science where consequences can be harmful, what happens is so complex it’s impossible to observe everything. To help make sense of it all, scientists use statistics.

Scientists run experiments to test new medicine. They do each experiment many times, recording their results. At the same time, they can run each experiment without the new medicine, instead using a fake treatment called a placebo, and they repeat this lots of times as well.

Growing food in an easy and affordable way

Agriculture and ScienceAgriculture plays a key role in the economy of every country. A country without sustainable food reserves will be forced to import food on a regular basis and this will have a huge impact on the government budget. Most government worldwide has put a lot of money towards improving agriculture. Large scale agriculture is practiced worldwide as a means of providing food for the people living in the urban areas. However, with the advancement in Agriculture and science, homeowners can cut down on costs of groceries by growing foods in an easy an affordable way. Through science, homeowners in urban areas can easily grow groceries in a limited space with ease helping save on expenses.

DNA Data Storage to Provide Unlimited Storage Capacities

DNAResearch is constantly being carried out to find methods of digital data storage that will have limitless capacities of holding data and one of the most recent techniques being researched on involves storing data in form of DNA molecules. For many years, DNA has been used by biological systems to store information but until recently, this technique had not been explored extensively to find out whether it could be used to store other kinds of data as well.

A team of researchers at the European Bio informatics Institute of the European Molecular Biology Laboratory have come up with proof to show that DNA molecules could hold more data than previously imagined. Headed by Nick Goldman and Ewan Birley, this team has demonstrated the potential that DNA molecules possess for storing and transporting man made data. Continue Reading

Computer Simulation Indicate Grandmothers Extend Humans Longevity and Could Increase Ape Lifespan

ApesThe “grandmother hypothesis” has received mathematical support from a recent study involving computer simulation. This renowned theory postulates that human developed longer lifespan as adults than apes due to grandmothers helping in the feeding of their grandchildren. The theory was first advanced in 1997 by university of Utah anthropologists Kristen Hawkes and James O’Connell, together with Nicholas Blurton Jones, an anthropologist at UCLA.

Kristen Hawkes, a prominent anthropology professor at Utah University conducted this recent study together with Peter Kim, a mathematical biologist and former postdoctoral researcher at the same university currently based in university of Sydney and James Coxworth, an anthropology doctoral student at the University of Utah. The study was financed by the Australia’s Research Council and National Science Foundation.

The computer simulation shows that animals with lifespan similar to Chimpanzees evolve to acquire human lifespan in less than 60,000 years with a little “grandmothering”. While human females live for a number of decades after child bearing, female chimpanzees hardly ever live past their child-bearing years, which are normally their 30’s and at times their 40’s. This simulation did not consider assumptions about the human brain size. Continue Reading

Hard x-ray Angle-Resolved PhotoEmission

A major breakthrough in spintronics

Hard x-ray Angle-Resolved PhotoEmission Traditionally, data processing relies on the “charge” of an electron, however a new technology called “Spintronic” is looking to turn the semi-coductor industry on its head by using an electron’s “spin” instead. This development should allow for high speed, micro-sized, and highly efficient storage and data processing semi-conductors.

The most important development for spintronics has been the development of dilute-magnetic semiconductors. These semiconductors are similar to traditional semi-conductors, however magnetic atoms are added, making the semi-conductors ferromagnetic. Ferromagnets are permanent magnets. This represents a significant step forward as one of the largest impediments to understanding ferromagnetism in dilute-magnetic semi-conductors has been removed.

This research is the result of the coordinated efforts of numberous researchers under the leadership by the U.S.-Department of Energy’s Berkeley Lab. By using the new Hard x-ray Angle-Resolved-PhotoEmission Spectroscopy (HARPES) technique scientists have discovered that gallium manganese Arsenide gains its ferromagnetism from two separate mechanisms.

The recombined deadly virus as a result of chicken vaccines

chickensScientists have found that n some Australian farms, vaccines are causing diseases, due to the effect of two virus strains present in chicken vaccination, recombining to form a deadly virus. Glenn Browning says that this shows that indeed recombination can happen and that people should be wary of it.

All around the world chickens are vulnerable to a class of herpesviruses known as ILTV, which attack the bird’s upper respiratory system. When this happens, it results to infectious laryngotracheitis, reduces the number of eggs produced and may kill around one-fifth of the infected chicken. Browning says that this death is caused by choking on mostly mucus and blood. Current knowledge indicates that the deadly virus infects only chickens and other similar birds.

Farmers can fight ILTV by vaccinating their chickens with less virulent herpesviruses that don’t cause the disease. Australia has been using SA2 and A20 vaccines produced by Pfizer. Continue Reading

Feathered dinosaur fossil discovered

dinosaurThe ancestor of all dinosaurs may have been a feathered creature. This is according to a newly unearthed fossil of a young dinosaur estimated to have lived around 150 million years ago. The fossil strongly suggests that dinosaurs may have had sported feathers. Unlike other previously discovered fossils of feathered dinosaurs, this one has been found to have a more distant relation to birds. The feathers found on the fossil are thin, flexible and resemble basic strands of hair. Though they are made of the same fundamental materials and have the same underlying architechture of modern day feathers, they have a very different appearance. They have thus been named “protofeathers” or “type 1 feathers” while those found in birds nowadays are considered “type 2 feathers”.

The fossil belongs to a family of giant dinosaurs known as megalosaurs. Though it measures 70 centimeters, it could have grown to a length of 10 meters. Megalosaurs were distinguished by their strong and heavy frames,very sharp teeth and massive claws. It has been biologically named as the Sciurumimus albersdoerferi. Continue Reading

How ultra-tough mantis craws can make iprovement in body armor

mantisThe ultra tough mantis craw can be able to give a better body armor if mimicked. This is true according to the research done by Harvard University. This creature has strong punch perhaps no creature can be compared with it considering how small it is. Most of it delicious meals are crabs, snails and other crustacean creatures. Feeding on them is made possible by hammer like craws, which are used to smash the tough body of their prey. These craws can be able to deliver 500 Newton forces, which is enough to break through an aquarium glass.

How do crustaceans able to survive when their craws are always intact? This is the question, which people may wish to be answered. It is proven that they involves three prolong structures that are known to be stronger and tougher than any manmade materials. They have multiple structures in their craws, which are able to protect them against breakage. Groups of scientist who have done this research from Harvard University led by James Weaver say that if people can be able to mimic these structures, human being can have best body armor. In the scientist words the beautiful mantis can be compared to the “armored caterpillar.” It has a unique body parts such its compound eyes that are complex and can be able to see from ultraviolent to infrared. This makes it to be special animal and well known by many. Continue Reading

Monitoring Software

The Internet can be tricky for parents to deal with because kids often need to use the Internet for school, but parents parents are often worried about the various activities that their children might be engaged in. Peer-to-peer file sharing can lead to lawsuits and even a criminal prosecution. Some teens might engage in activities online that are embarrassing to the family or may lead to viruses or hackers accessing the computer. Fortunately, there are various forms of monitoring software that can offer parental control.

Monitoring software can also be very helpful when parents are trying to learn what their children are up to, such as whether they are attending class or doing their homework.

Many teens use the computer purchased specifically for schoolwork to play computer games or chat with friends. Monitoring software can not only record activities on the computer, but smartphone software such as Mobile Spy can silently record the teen's GPS information, text messages and phone call information.

Monitoring software sits silently on a computer or mobile device and monitors all of the activities carried out on the device, encouraging the teen to consistently use the device for communication. Activity is usually uploaded to an online account so that the parent can monitor activity from anywhere without having to get close to the phone. This is crucial since parents will usually not have physical access to the phone without arousing suspicion.

Many monitoring programs also come with keystroke loggers, which log keys recorded on the computer, a contextual blocker, and features that allow parents to block certain websites. All of these features allow parents to have a peace of mind when allowing their teens to use the Internet.
