    Volcanoes helped species survive ice ages

    An international team of researchers has found evidence that the steam and heat from volcanoes and heated rocks allowed many species of plants and animals to survive past ice ages, helping scientists understand how species respond to climate change.

    The research could solve a long-running mystery about how some species survived and continued to evolve through past ice ages in parts of the planet covered by glaciers.

    The team, led by Dr Ceridwen Fraser from the Australian National University and Dr Aleks Terauds from the Australian Antarctic Division, studied tens of thousands of records of Antarctic species, collected over decades by hundreds of researchers, and found there are more species close to volcanoes, and fewer further away.

    “Volcanic steam can melt large ice caves under the glaciers, and it can be tens of degrees warmer in there than outside. Caves and warm steam fields would have been great places for species to hang out during ice ages,

    Well, it’s Sunday again. It’s our time to recapitulate all the scientific contributions, ideas, events and discoveries that have occurred in this week. To be honest, the job was quite challenging, since the science and technology market is highly competitive and unpredictable. Luckily, we made it. Now we would like to present you top stories that were published during this week.

    How to learn like a memory champion

    For most of his 20s, Ed Cooke had been hovering around the top 10 of the World Memory Championships. His achievements included memorising 2,265 binary digits in 30 minutes and the order of 16 packs of playing cards in just an hour. But at the age of 26, he was getting restless, and wanted to help others to learn like him. “The memory techniques take a certain discipline,” he says. “I wanted a tool that would just allow you to relax into learning.”

  • The Origin of Water on Earth

    The Origin of Water on Earth

    The reason that there is clearly more water on the Earth than on the other planets of the Solar System has not been clarified. There are few theories on how the world’s oceans were formed over the past 4.6 billion years.

    Some of the most likely contributory factors to the origin of the Earth’s oceans are as follows:

    (1) The cooling down of the primordial world to the point where the outgassed volatile components were held in an atmosphere,
    (2) Comets, trans-Neptunian objects or water-rich meteoroids,
    (3) Measurements of the ratio of the hydrogen isotopes deuterium and protium point to asteroids,
    (4) Biochemically, during the Great Oxygenation Event, via redox reactions and photosynthesis,
    (5) Gradual leakage of water stored in hydrous minerals,
    (6) Photolysis: radiation can break down chemical bonds on the surface,
    (7) Planetesimals heated by the decay of aluminum.

    The reasons why we have water on Earth are presented in the following video material.

  • How to Remain Cyber Safe?

    How to Remain Cyber Safe?

    Over the decades security experts all around the world have been debating what sort of protection is the most suitable for a PC. So, what do you think you should do to keep your computer cyber safe?

    Below are some key steps to protecting your computer from intrusion:

    Keep Your Firewall Turned On

    A firewall assists in protecting your computer from hackers who might try to gain access to crash it, delete information, or even steal passwords or other sensitive information. Software firewalls are widely recommended for single computers. For multiple networked computers, hardware routers typically provide firewall protection.

    Install or Update Your Antivirus Software

    Antivirus software is designed to prevent malicious software programs from embedding on your computer. If it detects malicious code, like a virus or a worm, it works to disarm or remove it. Viruses can infect computers without users’ knowledge. Most types of antivirus software can be set up to update automatically.

    Install or Update Your Antispyware Technology

    Spyware is just what it sounds like—software that is surreptitiously installed on your computer to let others peer into your activities on the computer. Some operating systems offer free spyware protection, and inexpensive software is readily available for download on the Internet or at your local computer store.

    Keep Your Operating System Up to Date

    Computer operating systems are periodically updated to stay in tune with technology requirements and to fix security holes. Be sure to install the updates to ensure your computer has the latest protection.

    Be Careful What You Download

    Carelessly downloading e-mail attachments can circumvent even the most vigilant anti-virus software. Never open an e-mail attachment from someone you don’t know, and be wary of forwarded attachments from people you do know.

    Turn Off Your Computer

    With the growth of high-speed Internet connections, many leave their computers on and ready for action. The downside is that being “always on” renders computers more susceptible.

    The Science of Which Came First, the Chicken or the Egg, Animated

    What the ancient proto-chicken has to do with how wolves became dogs.

    Since the dawn of recorded history, philosophers have pondered which came first, the chicken or the egg, as a causality dilemma exploring grander existential inquiries into the origin of life and the universe. But, it turns out, science has an answer that bypasses the metaphysical and dives right into the nitty-gritty of the tangible and concrete. In yet another illuminating animation, AsapSCIENCE enlist evolutionary biology in answering the age-old question, comparing the process to how dogs became dogs and ultimately demonstrating that — like much of science — the solution may have more to do with semantics and nomenclature than with actual scientific evidence.

    The Occupation of Parents Defines Kid’s Results at School

    Children who have at least one parent working in IT, business or engineering are the best performing students in Australia.

    An OECD report into the connection between student performance and their parents’ occupations has also found the kids of subsistence farmers, salespeople and machine operators are the lowest performing students in the nation’s schools.

    Not only were the kids of information and communications technology (ICT) workers top of the country in maths and science, they were also the best in terms of reading.

    By Australian Information Industry Association, ICT workers’ skills include the analytical, the innovative, the creative thinking, the can-do, curiosity and solving business problems.

    These means that the children of ICT workers are enjoying the benefits of being exposed to all of those skills and being inspired in their family environment to take risks.

    But, that’s not the end of the story. The gap between Australia and the top maths performers is so big that the children of a Shanghai (China) subsistence farmer will perform as well as the offspring of an Australian health or teaching professional.
