Big Data: Astronomical or Genomical?
Genetics is poised to overtake astronomy, YouTube and Twitter as a data-generating champion, Michael Schatz, a quantitative geneticist at Cold Spring Harbor Laboratory in New York and colleagues say. Challenges for collecting, analyzing, storing and sharing genetic data are already at least on par with some of the other most demanding big data endeavors, the researchers report July 7 in PLOS Biology.

The amount of genetic data doubles about every seven months. By 2025, researchers may have deciphered, or sequenced, 100 million to 2 billion human genomes — each the full set of genetic instructions for a person and each containing more than 3 billion DNA bases. Researchers are also compiling genetic data from thousands of species of microbes, animals and plants. No one knows for sure how much genetic information is currently available; thousands of laboratories around the world have DNA sequencing machines and most of the data are not yet in public databases.
If the doubling trend continues, genetics will soon catch up to radio astronomy’s vast data collections, Schatz says. He proposes that “genomical” may one day replace “astronomical” as an expression of gargantuan proportions. “Whether people will adopt ‘genomical,’ only time will tell,” he says.

Abstract

Genomics is a Big Data science and is going to get much bigger, very soon, but it is not known whether the needs of genomics will exceed other Big Data domains. Projecting to the year 2025, we compared genomics with three other major generators of Big Data: astronomy, YouTube, and Twitter. Our estimates show that genomics is a “four-headed beast”—it is either on par with or the most demanding of the domains analyzed here in terms of data acquisition, storage, distribution, and analysis. We discuss aspects of new technologies that will need to be developed to rise up and meet the computational challenges that genomics poses for the near future. Now is the time for concerted, community-wide planning for the “genomical” challenges of the next decade.

A new kind of subatomic particle called the pentaquark has been detected for the first time, the European Organization for Nuclear Research said on 14th July, 2015.
The lab, known by its French acronym CERN, said the findings were made by a team of scientists working on the LHCb experiment, one of the four at its Large Hadron Collider.
The existence of pentaquarks was first proposed in the 1960s by American physicists Murray Gell-Mann and Georg Zweig. Gell-Mann, who received the Nobel Prize in 1969, coined the term "quark" to describe the building blocks that make up hadrons — subatomic particles such as the proton and the neutron.
Until recently, only hadrons with two or three quarks had been found. In recent years, physicists have seen evidence of hadrons made up of four quarks, called tetraquarks.
Studying pentaquarks may help scientists to better understand "how ordinary matter, the protons and neutrons from which we're all made, is constituted."

This is What Happens When Mosquitoes Bite:

When a mosquito bites you, it injects an anticoagulant into the skin to make the blood thinner and flow easier and longer to feast on enough of your blood.
In reaction, the skin releases histamine, causing an inflammatory reaction. The skin gets red and forms a bump. If left alone, the swelling and redness often goes away quickly. If scratched or rubbed or if the individual has an allergic reaction, the little bump can swell considerably or even become infected.
So don’t scratch the mosquito bite! Scratching the itch of the bug bite might provide temporary relief but it also causes more skin trauma and this can lead to hyperpigmentation. Scratching can also allow bacteria from your fingertips and under the fingernails to get into the small break in the skin caused by the bite and cause an infection.

How to deal with it:

When you get a mosquito bite, cleanse the area with a gentle soap or cleanser. Acu- Life Poison Ivy Soap, while for the relief of poison ivy, oak and sumac, actually relieves the itch from mosquito bites.

If the mosquito bite itching persists:

*try an anti-itch cream with hydrocortisone like Cortizone 10 Hydrocortisone Anti Itch cream
*try an antihistamine like Benadryl Itching Stopping Gel
*there are other anti-itch creams and gels like After Bite (which contains ammonium) and After Bite Outdoors (ammonium and baking soda and tea tree oil) that some sufferers have found provide relief
*calamine lotion has also been suggested for insect bites, but it’s debatable whether it really stops itching. Calamine lotion seems to help more with a rash or irritation caused by the mosquito bite. Women who are pregnant or nursing shouldn’t use calamine lotion. It’s also a good idea to ask your doctor if calamine will interact with any medicines you’re taking.

• Apply ice to reduce swelling.
• Aloe vera is an anti-inflammatory that can be used to soothe a bite and lessen the itching, as well as help heal the skin. You can dab the gel or juice on the bite.
• Mix baking soda and water until you make a paste and apply to bites. (You can also use baking soda toothpaste.)
• Make a paste of aspirin and water and apply to bites.
• Rub the affected area with an onion slice immediately after the bite to stop the itching. Onion is an anti-inflammatory. (If you rub it on after scratching the area, it will sting.)
• Take a colloidal oatmeal bath to sooth itching.
• Rub tea tree oilon the bite. Tea tree is an antiseptic and can kill bacteria and reduce allergic skin reactions.

Science Journalism! Well that is one of the things I do! I am a freelancer though!

Great work.Does anyone here work in the scientific journalism field?I think the creator of this grp does?

DSM honors scientists around the world
Royal DSM, a science-based company active in nutrition, health and materials, recently launched a campaign to honor scientists around the world including one working to fight malaria.

In addition to paying tribute to the scientists, the Bright Science campaign is designed to encourage discussions about how important science is for society. The campaign emphasizes major societal needs via inspiring storytelling. A short documentary describing the perseverance and personal sacrifices of scientists around the world is the centerpiece of the campaign.

The documentary, titled Unsung Heroes of Science, shows how scientists in the future will use their discoveries to feed 9 billion people in 2050, create a bionic walking machine for disabled people, and transform methane gas into biodegradable plastics. One scientist, Bart Knols, leads a team that has created a plastic tube fitted with mosquito-killing gauze that can be built into roofs in Africa.

The general public, governments, customers, businesses, opinion leaders and others are invited to discuss their opinions about how science impacts social purpose at www.sciencecanchangetheworld.org
