Hair protein patterns better for DNA identification: Study

Hair protein patterns better for DNA identification: Study

US researchers have found a backup for DNA identification as human hair offer even better distinction compared to DNA, reported PLOS One journal on Wednesday. Based on protein changes in human hair, researchers at California’s National Laboratory provided an alternative method for DNA testing.

Researchers accidently create 'water-oozing' nanorods having large range of real-world applications

Researchers accidently create 'water-oozing' nanorods having large range of real-world applications

Researchers’ experiment didn't go as planned, resulting into the formation of nanorods by chance, they closely analyzed the microscopic, unplanned spawns of science. Using a vapor analysis instrument, Chemist Satish Nune was scrutinizing the solid, carbon-rich nanorods, and he noticed that the nanorods strangely lost weight with the rise in humidity.

Nune and his colleagues thought that the instrument had malfunctioned, and shifted their attention to another tool, a high-powered microscope.

Newton’s handwritten mid-17th-century document unveils his alchemical reading

Newton’s handwritten mid-17th-century document unveils his alchemical reading

The Chemical Heritage Foundation, a non-profit based in Philadelphia, has been able to get control of Isaac Newton’s manuscript through an auction carried out in February 2016. For most of the 20th century, the mid-17th century handwritten manuscript was in private hands.

The document has the formulas that Newton once hoped to use in his alchemic work. Among them include the instructions required to create sophick mercury, a substance needed to make the legendary Philosopher’s stone.

Four new elements enter Periodic table

Four new elements enter Periodic table

The periodic table has got four new elements. The inclusion has made all the science books across the world outdated. The table’s seventh row will now get elements 113, 115, 117 and 118, making it complete. The decision has come after the International Union of Pure and Applied Chemistry verified them on December 30.

But the latest elements haven’t received their final names or symbols yet. A team from Japan, Russia and the USA has discovered the new elements and will all give the name to their own new elements.

Gene-Editing Technique CRISPR Wins Breakthrough of the Year Award

Gene-Editing Technique CRISPR Wins Breakthrough of the Year Award

Well-known US journal Science on Thursday named the gene-editing technique called CRISPR as 2015’s breakthrough of the year. The technique has been given the title after knowing its potential to revolutionize health and medicine.

The method gave rise to controversy after Chinese researchers said earlier this year that they had deliberately edited the DNA of nonviable human embryos from a fertility clinic.

Gene-editing technology is Science magazine’s 2015 ‘Breakthrough of the Year’

The 2015 ‘Breakthrough of the Year’ has been unveiled by Science magazine and a gene-editing technology is the winner. According to experts, the technology is going to change life as it potentially will be revolutionizing basic science, medicine and agriculture.

With the help of the gene-editing tool known as CRISPR, derived from a bacterial protein, scientists can alter, cut and paste particular portions of DNA. This would offer a path to fresh genetic diseases’ treatments or cures.

Over-prescription of opioid painkillers is being driven by large number of general practitioners, find researchers

Over-prescription of opioid painkillers is being driven by large number of general practitioners, find researchers

In a new study, researchers have discovered that opioid painkillers’ overprescription is being driven by a huge number of general practitioners, not by specialists or ‘pill mill’ operations as suggested by many.

Conducted at Stanford University, the study has contradicted theories and efforts spanning many years to close down the corrupt clinics that have been giving the drugs out to everybody asking out for them.

Graphene could be used to create fuel-free spacecraft

Graphene could be used to create fuel-free spacecraft

According to researchers, graphene could be used to create fuel-free spacecraft that works using sunlight. As per reports, these sheets of carbon one atom thick can convert light into action and this could be the foundation of a fuel-free spacecraft. Flat structure of graphene is quite strong; it is a very good conductor of electricity and heat.

Chemistry Teacher Suffers First and Second-Degree Burns While Conducting Experiment

At the time of conducting experiment on Wednesday, a chemistry teacher suffered first- and second-degree burns. According to officials, Silja Paymer was conducting a demonstration in front of class at Palo Alto High School when a chemical reaction led to a fire and her clothes and hair caught fire.

Tampons provide a Way to Detect Sewage Leaks

Tampons provide a Way to Detect Sewage Leaks

Researchers have devised a new way to detect sewage leaks. They placed tampons in 16 surface water sewers and retrieved them after 3 days. After this, they tested them under UV light. The research team successfully detected grey water contamination. They also determined a positive and negative result for clean water.

The researchers explained that the natural, untreated cotton in tampons readily absorbs chemical commonly used in toilet paper, laundry detergents and shampoos. Known as optical brighteners, these chemicals enhance whites and brighten colors.
