Syria chemical 'attack': Trump condemns 'affront to humanity'

US President Donald Trump has denounced the murdering of many regular citizens in northern Syria in a clear substance weapons assault by Syria's aviation based armed forces.

He didn't say Russia, Syria's partner, which says substance weapons in revolt hands may have been discharged.

Be that as it may, America's emissary to the UN blamed Russia for concealing for Damascus

"Over and over Russia utilizes the same false story to redirect consideration from their partner in Damascus," Nikki Haley said amid a warmed UN Security Council banter in New York.

Implying at conceivable one-sided activity by the US, she included: "When the United Nations reliably bombs in its obligation to act all in all, there are times in the life of states that we are constrained to make our own move." Read more:-International Database

The administration of Syrian President Bashar al-Assad denies its strengths propelled a substance weapons assault.

How Princess Diana changed attitudes to Aids

In the mid-80s, the world was unnerved by HIV/Aids brought about by an absence of comprehension and falsehood.

Before the world's media, Princess Diana shook the hand of a man enduring with the ailment.

She did as such without gloves, openly difficult the thought that HIV/Aids was passed from individual to individual by touch.

She appeared in a solitary motion this was a condition requiring sympathy and comprehension, not dread and numbness.  Read more:- Mobile Number Database Provider

He addressed Witness about a point of interest minute in the battle against HIV/Aids.

Extra letters added to life's genetic code

Scientists have created bacteria that thrive using an expanded "genetic alphabet".

The blueprint for all life forms on Earth is written in a code consisting of four "letters": A, T, C and G, which pair up in the DNA double helix.

But the lab organism has been modified to use an additional two, giving it a genetic code of six letters.

Researchers hope the work could lead to bugs that can help manufacture new classes of drugs to treat disease.

The team from the US, China and France have published their work in PNAS journal.

Previous research had shown that an "unnatural base pair" (UBP), consisting of two synthetic letters called X and Y, could be incorporated into the DNA of Escherichia coli bacteria.

But the resulting bugs grew slowly, and the UBP was expunged after several rounds of cell division.

Now, Prof Floyd Romesberg, from The Scripps Research Institute in La Jolla, California, and colleagues, have shown that their single-celled organism can hold on indefinitely to the synthetic base pair as it divides.

"We've made this semisynthetic organism more life-like," said Prof Romesberg, senior author of the new study.

"Your genome isn't just stable for a day," said Prof Romesberg. "Your genome has to be stable for the scale of your lifetime. If the semisynthetic organism is going to really be an organism, it has to be able to stably maintain that information."

Key to the advance was a modification to a molecular transporter, which helps the E. coli bugs import the UBP.

Next, the researchers optimised their previous version of Y so that it could be better recognised by the enzymes that synthesise DNA molecules during replication.

Finally, the researchers set up a "spell check" system for the organism using the CRISPR-Cas9 genome editing tool. Cheap Dedicated Server Canada

They were able to take advantage of the tool to ensure that any cells that dropped X and Y would be marked for destruction.
Their semisynthetic organism was thus able to keep X and Y in its genome after dividing 60 times, leading the researchers to believe it can hold on to the base pair indefinitely.

Barack Obama pays tribute at Hiroshima nuclear memorial

Barack Obama on Friday paid tribute to the 140,000 people killed by the world's first atomic bomb attack and sought to bring global attention to his unfulfilled vision of a world without nuclear weapons, as he became the first sitting US president to visit Hiroshima.

"Death fell from the sky and the world was changed," Obama said, after laying a wreath, closing his eyes and briefly bowing his head before an arched monument in Hiroshima's Peace Memorial Park that honors those killed on August 6, 1945, when US forces dropped the bomb that ushered in the nuclear age. The bombing, Obama said, "demonstrated that mankind possessed the means to destroy itself."

Obama did not apologize, instead offering, in a carefully choreographed display, a simple reflection on the horrors of war and his hope the horror of Hiroshima could spark a "moral awakening." As he and Japanese Prime Minister Shinzo Abe stood near an iconic bombed-out domed building, Obama acknowledged the devastating toll of war and urged the world to do better.

"We stand here in the middle of this city and force ourselves to imagine the moment the bomb fell ... we listen to a silent cry." Obama said.

A second atomic bomb, dropped on Nagasaki three days later Hiroshima, killed 70,000 more.

Obama also sought to look forward to the day when there was less danger of nuclear war. He received a Nobel Peace Prize early on his presidency for his anti-nuclear agenda but has since seen uneven progress.

EgyptAir flight MS804 to Cairo disappears from radar

EgyptAir flight 804 travelling from Paris to Cairo has disappeared from radar with 56 passengers and 10 crew members on board, the airline has said.

French President Francois Hollande said in a televised address that the plane had crashed early on Thursday.

The plane made "sudden swerves" mid-air and plunged before dropping off radars in the southern Mediterranean, Greece's defence minister said.

"At 3:39am the course of the aircraft was south and south-east of Kassos and Karpathos [islands] ... immediately after it entered Cairo FIR and made swerves and a descent I describe; 90 degrees left and then 360 degrees to the right," Defence Minister Panos Kammenos told a news conference.

Greek authorities mounted a search in the area south of the island of Karpathos without result so far, he said.

However, Egypt's civil aviation ministry said in a statement it was too early to confirm if the passenger plane had crashed.

According to EgyptAir, the plane took off from Paris' Charles De Gaulle Airport shortly after 11pm local time.

Greece is deploying military aircraft and a frigate to an area in the southern Mediterranean its defence ministry said.

The search for the missing EgyptAir plane was taking place at sea, about 130 nautical miles southeast of the island of Karpathos, the Greek defence ministry told Reuters news agency.

"One C-130 aircraft and an early-warning EMB-145H plane are already operating in the area. Another C-130 plane is on standby at Kasteli airport on the [southern Greek] island of Crete," Greece's military command said.
