A team of researchers spent weeks to know more about orb-weaving spiders and found some changes in the size and habitat of these spiders in Australia

Spiders residing in urban areas are healthier and bigger

The study consists of a collection of 222 mature female golden orb-weaving spiders, which are commonly found in urban and natural environment. The team observed the differences in the size, weight, fat reserves and height of these spiders and compared these components with the initial data and findings.

The team discovered that these spiders have better reproductive abilities and larger bodies, compared to their relatives in the countryside.

One of the scientists – Elizabeth Lowe shared her findings with the BBS news and said; “Hard surfaces and lack of vegetation lead to the well-known ‘urban heat island’ effect, with more heat retained than in areas with continuous vegetation. The high temperature is associated with increased growth and size in invertebrates. This increase in prey would result in bigger, heavier, more fecund spiders. By gaining a better understanding of the impacts of urbanization on wildlife in cities, we can work towards creating healthy, functioning ecosystems in urban areas.”

Lowe also commented that they would continue to monitor the health and growth of these spiders for some more time, so that their firm findings would further help in the study of urban spiders in medical journals.

Are the social networking sites such as Facebook safe for the kids? A recent survey held to find an answer to this question, gave insight to many concerns posed by people

Security reasons forces parents to keep their babies’ info off from social sites

Despite many assurances given by these social sites in the security and data privacy of its users, parents are finding it unsafe to upload the pictures of their kids.

Some of the concerns posed by these parents were that it is easy for anyone to check their pictures, find information about their location and check what tasks they are doing currently.  One of the parents residing in California – Sonia Rao, gave a statement about her concern of publicizing the identity of her 1-year-old kid.

According to her statement she said; “I just have a vague discomfort having her photograph out there for anyone to look at. When you meet a new person and go to their account, you can look them up, look at photos, videos, and know that they are traveling.”

Other concerns expressed by a few parents were about some companies who may misuse their kid’s images and personal data for their own cause.

“If I don’t want somebody to know about my child, to take an active interest in them, to recognize them in a city street or as they are leaving the schoolyard, the easiest way to do that is to not have any identifying information out about them.” said Scott Steinberg, a technology consultant who has more than 4000 Facebook friends.

The discovery of a solar concentrator is made at the Michigan State University

Make a plastic home and a plastic phone with the help of solar energy

The team of researchers used transparent plastic for this invention. This creative plastic concentrator can be used to build buildings, manufacture phones and many such things.

Several attempts were made earlier about using LSC (Luminescent Solar Collecting) material,  but, the results was not up to the mark. The material was bright in color, thus not making it efficient for building a widespread area.

According to one of the researchers of the project – Richard Lunt, “No one wants to sit behind colored glass, It makes for a very colorful environment, like working in a disco. We take an approach where we actually make the luminescent active layer itself transparent.”

Lunt guarantees the durability of the material and assures the people for its cost affordability. He also added by saying; “It can be used in tall buildings with lots of windows or any kind of mobile device that demands high aesthetic quality like a phone or e-reader. Ultimately, we want to make solar harvesting surfaces that you do not even know are there.”

This is still a beginning of a new invention, and thus the pros and cons are yet to be cleared and specified more efficiently.

A warning was issued by the FBI to the healthcare industries to stay alert from the hackers

Chinese Hackers target U.S. Healthcare industry

The issue  was brought to the notice to the FBI after an incident of a cyber attack, at the head office of Longview Regional Medical Center. The hackers leaked the private data of millions of patients that were stored in the center’s commuting systems.

According to a statement provided by one of the news agencies; ““The FBI has observed malicious actors targeting healthcare related systems, perhaps for the purpose of obtaining Protected Healthcare Information (PHI) and/or Personally Identifiable Information (PII). These actors have also been seen targeting multiple companies in the healthcare and medical device industry typically targeting valuable intellectual property, such as medical device and equipment development data.”

It is a matter of big concern for the patients and their families, as these data leakages pose issues with their bank account details and other related information.

The FBI has stated that these hackers are from China who have been committing  these crimes and theft of stealing the trade secrets and trial data of various industries. One of the security officer officers – Jeff Schilling said; “Once I came into the civilian market in 2012, one of the first observations I made was that Big Pharma and medical technology was a major target.”

The recent study revealed the difference between the sleep patterns and timing of different cities

Which city sleeps the most?

According to the survey, Melbourne is the city to have the maximum sleep of 7 hours and 5 minutes. The cities to remain awake for the majority of the time are; Singapore, Tokyo and South Korea.

Singapore has very less hours of sleep, which is about 6 hours and 32 minutes, whereas, Tokyo beats the competition with only 5 hours and 46 minutes. South Korea is also in the list, where people sleep only for 5 hours and 55 minutes in a day.

The report of the collected data was published in the Wall Street Journal by Jawbone, who is known for their digitized wristbands of tracking sleep of its users.

Instead of a subject of discussion, this seems to be a matter of concern for the cities with lack of sleep, as per few health researchers. Sleep plays a vital role for a healthy life. It helps in the brain development and growth.

Sleep deficiency leads to irritability, mood swings, diabetes, obesity and gastric problems. Sleepless nights lead to restlessness throughout the day. The doctors believe that a person should have a minimum sleep of 7 to 8 hours a day and maximum 9 to 10 hours, to let the brain work at its best.
