Washington: As yet another mass shooting in the US put the spotlight back on the contentious issue of gun control, media reports said that there have been 204 mass shootings in as many days in 2015 so far.
Thursday night’s shooting by a white man at a Lafayette, Louisiana, movie theatre showing the comedy “Trainwreck”, that left two women killed and nine injured was the third deadly mass shooting in six weeks.
The alleged shooter John Russell “Rusty” Houser, 59, using a handgun he legally purchased from an Alabama pawn shop methodically shot 11 people by firing off one 10-round clip, according to Lafayette Police Chief Jim Craig.
“This was slow and methodical,” as the State’s Indian-American Governor Bobby Jindal put it. “This was not a single burst.”
The Mass Shooting Tracker, a crowd-sourced project of the anti-gun folks at the Guns Are Cool subreddit, according to the Washington Post, had listed 203 mass shooting events so far in 2015 before the Louisiana movie theatre shooting.
This year there were 18 mass shootings in April, 39 in May, 41 in June, and 34 so far in July, the Post said.
The theatre shooting was Louisiana’s eighth this year. There have been 10 in Ohio, 14 in California and 16 in New York.
“Will anything change?” the Post asked and itself answered “Probably not” noting the reaction to the shooting in Charleston, South Carolina, where a white young man shot and killed nine black worshipers at a historic church.
It “did produce a fruitful national conversation — not on guns, but on the symbolism of the Confederate flag, which the shooter adopted as a banner of his racist beliefs,” the Post noted.
“The morning after the third deadly mass shooting in six weeks, the presidential candidates acted as though they hadn’t seen the news,” the New York Times suggested looking at their reactions.
Though most denounced the shootings and called for prayers for the victims, “none of the presidential contenders offered policy solutions to address gun violence”, it noted describing it as a “reflection of the fact that gun laws are politically radioactive”.
Even “Jindal, who is mounting a long-shot candidacy for the Republican nomination, completely deflected questions on tougher gun laws, saying he would talk about ‘policy and politics’ another time”, Times said.
The leading Republican presidential candidates are overwhelmingly opposed to any effort to restrict access to guns, it noted.
The Democratic hopefuls have proposed gun control measures, but they too have been generally more focused on issues of economics, race and gender than gun violence, according to the Times.
Although President Barack Obama said this week that the failure to convince Congress to pass “commonsense gun safety laws” was one of the great regrets of his presidency, Times said “Congress is unlikely to close any of the loopholes in federal gun laws exposed by the recent shootings”.
Canadian researchers have discovered an overlooked gene that plays a major role in the development of antibodies, which help the immune system recognize and fight viruses including SARS-CoV-2, bacteria and other causes of infectious disease. The gene -- FAM72A -- facilitates production of high-quality antibodies by enabling the effect of an enzyme called AID (for Activation-Induced Deaminase), the researchers showed.
Immunologists have known for two decades that AID is essential to produce antibodies capable of clearing infections, but the full mechanism of its effect has remained unknown. "Our findings answer the long-standing question of how AID does its work," said Alberto Martin, a professor of immunology at the University of Toronto's Temerty Faculty of Medicine. "FAM72A helps AID to promote mutations in antibody genes that are essential for the development of effective antibodies," he added.

Genetic mutations that lead to lasting changes in DNA occur through a process called mutagenesis. In the context of antibody development, mutagenesis unfolds largely through the AID-driven mechanisms called somatic hypermutation and class switch recombination -- both of which help antibodies gain the diversity and potency they need to counter a wide range of pathogens.
The results published in the journal Nature will help researchers better understand antibody development broadly, but they also have implications for cancer. Uncontrolled mutagenesis in B cells that produce antibodies is linked to B cell lymphoma, and FAM72A is present at very high levels in other cancers such as gastrointestinal, breast, lung, liver and ovarian cancers.
"Our data show that high levels of FAM72A promote mutations in antibody genes, so increased levels of FAM72A could spur cancer development, progression or drug resistance by increasing mutagenesis,a Martin said. Martin's team is now exploring those possibilities. Intriguingly, unlike other mammals, humans have four gene versions of FAM72A and their roles in cancer and antibody production are still unknown.

Mahanadi Coalfields Limited (MCL), a subsidiary of Coal India will set up a 50 megawatt (MW) solar power plant in Odisha's Sambalpur at a total cost of Rs 301.92 crore, moving steadily towards its goal to achieve carbon neutrality by 2024. MCL has placed a turnkey order to set-up a 50 MW solar power plant with a Chennai-based firm M/s Hild Energy Ltd, which will establish this green energy project within a timeline of 10 months, the MCL said in a statement on Saturday.
This solar plant would cater to the captive power requirement of MCL. The Central PSU had successfully set-up a 2MW solar power plant in Sambalpur in 2014. The company said it has pledged a target of installing 182 MW of solar power by 2024 in order to become a net zero energy company, aligning itself to use cleaner forms of energy for coal production.

This 50 MW solar power project will reduce CO2 emission by 91,020 tonnes per annum and carbon offsets of around 24,824 tonnes per annum, claimed the MCL. MCL is the leading production subsidiary of Coal India, having mining operations in Angul, Jharsuguda and Sundargarh districts of Odisha. Having achieved the highest ever capital expenditure of Rs 2,419 crore in the financial year 2020-21, the company has coal production and dispatch targets of 163 million tonnes and 182 million tonnes, respectively.
MCL was the coal mining company to introduce environment-friendly surface miner technology, which contributes over 95 per cent in coal production. As another environment-friendly initiative, the company has successfully introduced vertical rippers for blast-less over-burden removal in Hingula and Kaniha opencast projects. (IANS/ MBI)

As the nation celebrated the 114th birth anniversary of his father - renowned poet Harivansh Rai Bachchan - megastar Amitabh Bachchan remembered his dad as he penned a heartfelt note for him. The actor took to his blog where he poured his heart out and also shared an unseen photo with his father. The image in question is from Big B's wedding in 1973, where the two are caught in a sweet moment as they look at each other.
Amitabh Bachchan wrote on his blog,
"My Father , my all .. November 27th his birth in the year 1907 .. Which makes it his 114th Anniversary .. He is in the heavens, with my Mother and they celebrate .. as do we , in thought word and deed .. (sic). But first."
He then posted the picture followed by elaborate paragraphs. The megastar wrote,
"Those rare moments when one would find himself rushing against the winds to prevent the distance between us and to close it down as soon as it can be. The day of my wedding and his expression of fulfilment to not just be in congratulation but instead to be in the face of a belief, a chime, an ultimate season of love and great passion, of the quarries of the fears and conditionings of these deprived gym routines kart ..(sic)". "This could have been unknown for long facilitating years, to give not expected versions and lastly large scale informations of the insides ; but as time passed by, as does now , they explained purposely, the values of education and similarity .. Be in peace and love .. (sic)",
the veteran actor concluded his note. (IANS/ MBI)
