         WE LOVE SCIENCE HERE BECAUSE IT IS A MANY SPLENDOURED THING

     THIS  IS A WAR ZONE WHERE SCIENCE FIGHTS WITH NONSENSE AND WINS                                               

“The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.”             

                    "Being a scientist is a state of mind, not a profession!"

                  "Science, when it's done right, can yield amazing things".

         The Reach of Scientific Research From Labs to Laymen

The aim of science is not only to open a door to infinite knowledge and                                     wisdom but to set a limit to infinite error.

"Knowledge is a Superpower but the irony is you cannot get enough of it with ever increasing data base unless you try to keep up with it constantly and in the right way!" The best education comes from learning from people who know what they are exactly talking about.

Science is this glorious adventure into the unknown, the opportunity to discover things that nobody knew before. And that’s just an experience that’s not to be missed. But it’s also a motivated effort to try to help humankind. And maybe that’s just by increasing human knowledge—because that’s a way to make us a nobler species.

If you are scientifically literate the world looks very different to you.

We do science and science communication not because they are easy but because they are difficult!

“Science is not a subject you studied in school. It’s life. We 're brought into existence by it!"

More than 15,000 scientists from 184 countries issue 'warning to humanity'

More than 15,000 scientists around the world have issued a global warning: there needs to be change in order to save Earth.

It comes 25 years after the first notice in 1992 when a mere 1,500 scientists issued a similar warning. 

This new cautioning — which gained popularity on Twitter with #ScientistsWarningToHumanity — garnered more than 15,000 signatures.

A team of researchers in Singapore has identified a molecular pathway that suppresses virus-induced cancers. They published their findings in PLOS Pathogens. Some cancers are known to be caused by viral infections. For example, two strains of the human papillomavirus (HPV) are responsible for up to 70 percent of cervical cancer cases. The virus causes abnormal cell growth by inserting its genetic material into the cells of the cervix. Uncontrolled cell growth is typically prevented by the shortening of telomeres—protective caps on the ends of chromosomes. Each time a cell divides into two, the telomeres get shortened, and the cell eventually stops dividing. Cancer cells, however, are known to bypass this limit by producing telomerase, an enzyme that extends the length of telomeres. In HPV-infected cells, the protein TIP60 is known to prevent progression to cervical cancer, but the interactions between TIP60 and telomerase remain unknown. In this study, researchers at the Cancer Science Institute of Singapore (CSI Singapore) and the National University of Singapore (NUS) examined the regulation of telomerase by TIP60 in virus-induced cancer cells. The team discovered that TIP60 inhibits telomerase by interacting with and modifying a partner molecule, Sp1. When TIP60 modifies Sp1, Sp1 can no longer bind to the regulatory sequences of the telomerase gene to activate it. This results in less production of telomerase, which prevents the cancer cells from continuous division. The identification of this molecular pathway opens a new window of hope for therapeutic interventions against cancers. “Our findings hold exciting potential in the fight against a range of virus-induced cancers, including cervical cancer, liver cancer and Burkitt’s Lymphoma,” said study corresponding author Dr. Sudhakar Jha, a principal investigator at CSI Singapore. “Given that 85 percent of cancers are triggered by high amounts of telomerase, our study, which lends a deeper insight into the inhibition of telomerase by TIP60, could also be applied to other groups of cancer such as breast, colorectal and ovarian cancer. Our next step is therefore to investigate the influence of this new pathway in these other groups of cancer,” he added. The article can be found at: Rajagopalan et al. (2017) TIP60 Represses Telomerase Expression by Inhibiting Sp1 Binding to the TERT Promoter.

How science is saving lives....

A team of researchers from Germany, Austria, and Italy gave a young boy with the genetic disease junctional epidermolysis bullosa (JEB) new skin cells that saved his life. The work is detailed in the Nature paper "Regeneration of the entire human epidermis using transgenic stem ce..."

JEB is caused by genetic mutations in the genes LAMA3, LAMB3 or LAMC2. These three genes are required to form the protein laminin - a key component of the extracellular matrix which acts like the glue that holds cells together. When one of these genes is mutated, the extracellular matrix is disrupted and the skin blisters, erodes, and has recurrent infections. This disease is a nightmare - resulting in pain while living and an early death.  

Altering a gene (in this case, making a correction) is done in labs all around the world every day. This team of scientists had talent to do this. They worked with a genetic disease with known mutations in cells that could be modified in cells that could then grafted back onto the patient.

The first step in the process was the correction of the genetic mutation.

This is potentially the least complicated step in this process. The scientists had all of the information and tools necessary to make this happen. The DNA was constructed and put into a virus that infects skin cells. This viral vector is an incredibly useful way to place DNA into cells. The new DNA then becomes part of the genome of the skin cell. In this process, the skin cell now has a corrected version of the mutated gene in their genome. 

The second step of the process was making more of the corrected cells. In this particular part of the process - as our skin is one of the few organs that have stem cells positioned in and amongst our normal skin cells (called keratinocytes)- these are not the frequently discussed pluripotent stem cells; instead, these stem cells are dedicated to making more skin. This is important for the normal wear and tear that happens to our skin. When the mutated gene was corrected in one of these cells, it would make more cells with the corrected gene. Over time, there were enough cells to graft onto the patient. 

Both of these two major steps are events that happen in labs across the world every day. But, like many significant advancements, this was made possible by a combination of the right problem, the right tools and good hands of motivated scientists. So, some good old fashioned genetic sequencing and cell culture have saved a boys life - and that is the most amazing scientific story of the year.

Earth’s multiscale microbial diversity Catalogue

A meta-analysis of microbial community samples collected by hundreds of researchers for the Earth Microbiome Project. Coordinated protocols and new analytical methods, particularly the use of exact sequences instead of clustered operational taxonomic units, enable bacterial and archaeal ribosomal RNA gene sequences to be followed across multiple studies and allow us to explore patterns of diversity at an unprecedented scale. The result is both a reference database giving global context to DNA sequence data and a framework for incorporating data from future studies, fostering increasingly complete characterization of Earth’s microbial diversity.

The time of day of your surgery could have long-term impacts on your health. That’s according to researchers who looked at the way circadian rhythm—the body’s internal clock—affects  the outcomes of a patient recovering from a complex heart procedure.

Patients who underwent open-heart surgery in the afternoon experienced better health outcomes compared to those who got operated on in the morning, study authors found after six years of observing nearly 600 patients who underwent heart valve replacement. In the subsequent 500 days after surgery, researchers found, those patients who had surgery after noon had half the risk of a major cardiac event—for instance myocardial infarction, acute heart failure, or death—as those who had surgeries before then.

University of Lille-France professor David Montaigne, the study’s lead author, suggests that the study’s findings indicate that scheduling changes could decrease injury or death.

“There are few other surgical options to reduce the risk of post-surgery heart damage, meaning new techniques to protect patients are needed,” Montaigne said in a statement. “Our findings suggest this is because part of the biological mechanism behind the damage is affected by a person’s circadian clock and the underlying genes that control it.”

The findings are the latest in a growing body of evidence suggesting that time of day plays an important role in how well various medical treatments work. Studies show that the efficacy of some vaccines and cancer treatments may be affected by the time of day when a therapy is administered or medicine is taken. For example, research has found that patients who received a seasonal flu vaccination before 11 a.m. produced more antibodies than those who had one after 3 p.m.

“This study underscores the importance of the circadian rhythm biology that’s finally starting to gain recognition in science. This could potentially save a lot of lives.

When the courts here banned bursting of Diwali fire crackers, several people , criticized it protested and disregarded the ban. But at what cost? Read this:

Pollution is the largest environmental cause of disease and death in the world today, responsible for an estimated 9 million premature deaths according to The Lancet Commission on pollution and health.

The new study, published in the journal The Lancet and written by more than 40 international health and environmental experts, uses data from the the Global Burden of Disease, an international study that examines trends across populations and estimates mortality from major diseases and their causes. It i t looked at the effects of air pollution, or air contaminated with things like gases and the burning of wood, charcoal and coal; water pollution, which includes contamination by things like unhygienic sanitation; and workplace pollution, where employees are exposed to toxins and carcinogens like coal or asbestos.

Air pollution was linked to 6.5 million deaths in 2015, water pollution was linked to 1.8 million deaths and workplace pollution was linked to nearly one million deaths. Deaths from pollution-linked diseases, like heart disease and cancer, were three times higher than deaths from AIDS, tuberculosis and malaria combined, the researchers found.

The authors also found that 92% of pollution-related deaths happen in low- and middle-income countries. In growing countries like India, China, Pakistan, Bangladesh, Madagascar and Kenya, the researchers say that up to one in four deaths can be tied to pollution. China and India had the greatest number of pollution-related deaths in 2015. That year, pollution in China was linked to 1.8 million deaths, and pollution in India was linked to 2.5 million deaths. 

The researchers note that their data are likely underestimates and do not reflect the entire burden of disease from pollution. For instance, the researchers didn't look at other contaminants, like the effects of endocrine disruptors, flame retardants and pesticides on human health and early deaths. Fuller says there isn't data of high enough quality or quantity on those health issues.

5000 years of science development in India is being shown in an exhibition in London, UK

  • First written zero on a 1700-year-old birch bark manuscript

  • Oldest artefact is set of weights that standardised mud brick production

  • Exhibition at UK’s Science Museum in London

     
A light scattering technique invented in the early 20th century and a fragile manuscript documenting the earliest known symbol for a numerical zero are among achievements of Indian science highlighted in an exhibition that opened this week at the Science Museum in London, UK.

Illuminating India, which runs until 31 March 2018, marks 70 years from the country’s independence by celebrating global contributions to scientific advancement, as well as photography, from 3000 BC to the present day.

Mainstream views of science and technology tend to be Eurocentric, according to the curator, and the aim of the exhibition is to “redress that balance” by bringing India’s contribution to the centre.

He pointed to a set of standardised weights, the oldest artefact on display, as an example of how early scientific thought made it possible – through the production of mud bricks of standardized sizes – for the Indus Valley Civilisation to build large cities comparable to those later built by the Romans.
The scientific achievements on show range from space exploration – through early astronomy and India’s modern space programme – to the Great Trigonometrical Survey that mapped the subcontinent in the nineteenth century, and to the study of nature through technology such as Raman spectrometry, a light-scattering technique still used today to analyse the make-up of different materials.

Pesticides in natural honey!

WHEN researchers collected honey samples from around the world, they found that three-quarters of them had a common type of pesticide suspected of playing a role in the decline of bees.

Even honey from the island paradise of Tahiti had the chemical.

That demonstrates how pervasive a problem the much-debated pesticide is for honeybees, said authors of a study published Thursday in the journal Science.

They said it is not a health problem for people because levels were far below governments’ thresholds on what’s safe to eat.

“What this shows is the magnitude of the contamination,” said study lead author Edward Mitchell, a biology professor at the University of Neuchatel in Switzerland, adding that there are “relatively few places where we did not find any”.

Over the past few years, several studies — in the lab and the field — link insecticides called neonicotinoids, or neonics, to reduced and weakened honeybee hives, although pesticide makers dispute those studies.

Neonics work by attacking an insect’s central nervous system; bees and other pollinators have been on the decline for more than a decade and experts blame a combination of factors: neonics, parasites, disease, climate change and lack of a diverse food supply.
