Study: Some general anesthesia affects region of brain responsible for memory

Health
April 1 (UPI) -- Different general anesthetics used during surgical procedures cause chemical changes in patients' brains, affecting memory, a study published Thursday by PLOS Biology found. Three commonly used combinations of anesthetics, tested on mice, all changed brain activity in the hippocampus -- the region of the brain responsible for memory -- compared to "wakefulness," or not being under anesthesia, or natural sleep, the study showed. Advertisement All anesthetics tested in the study affected the stability of synaptic connections between brain cells in the hippocampus. Two of the three combinations also caused retrograde amnesia, a form of memory loss impacting events occurring immediately before surgery, the researchers said. "Anesthetic procedures are among the safest medical...
Facebook responsible for 94% of child sex abuse images reported by US tech firms

Facebook responsible for 94% of child sex abuse images reported by US tech firms

Technology
Facebook was responsible for 94% of the 69 million child sex abuse images reported by US technology companies last year.The figures emerged as seven countries, including the UK, published a statement on Sunday warning of the impact of end-to-end encryption on public safety online. Facebook has previously announced plans to fully encrypt communications in its Messenger app, as well as its Instagram Direct service - on top of WhatsApp, which is already encrypted - meaning no one apart from the sender and recipient can read or modify messages.The social media site said the changes are designed to improve user privacy on all of its platforms.But law enforcement agencies fear the move will have a devastating impact on their ability to target paedophiles and protect children online. ...
The common “Code for Responsible Lending” (CRL) for microfinance has a few big names missing

The common “Code for Responsible Lending” (CRL) for microfinance has a few big names missing

Finance
The common “Code for Responsible Lending” (CRL) for microfinance has a few big names missing from it, at least for now, putting a question mark over its impact and likelihood of success in its current form. Bandhan Bank, the country's largest microfinance player with one-fifth market share, has declined to be a part of the code in its current form. HDFC Bank with growing microfinance business too has not signed yet, even as lenders such as Axis Bank, Kotak Mahindra Bank and IndusInd Bank have signed it, two people familiar with the development said. Bandhan Bank Managing Director Chandra Shekhar Ghosh said that the code in its current form is restrictive for the bank’s business growth. He said the code should have spelt out what should be the ideal business conduct instead of limiting the...

Saudi oil attack: ‘Looking like’ Iran was responsible, says Trump

World
By Sanya Burgess, news reporter Donald Trump has said it is "looking like" Iran was behind the attacks on Saudi Arabia's oil facilities but has insisted that he does not want war.The US president said he was not looking at retaliatory options until he has "definitive proof" that Tehran was responsible, but added that America is prepared if a response is warranted. Iran has rejected claims it was to blame for Saturday's drone attacks, which damaged the world's biggest crude processing plant in Saudi Arabia and triggered the largest jump in crude prices in decades.

Area in Africa responsible for 1 billion tons of carbon emissions

Area in Africa responsible for 1 billion tons of carbon emissions

Science
Aug. 13 (UPI) -- New analysis of satellite data suggests between 1 and 1.5 billion tons of carbon emissions is emitted from northern tropical Africa each year. The latest research, published this week in the journal Nature Communications, suggests land use changes and drought have degraded the region's soil, leading to the release of large quantities of stored carbon. However, scientists say soil degradation alone isn't responsible for the region's carbon emissions. To identify other sources of released carbon, study authors suggest more research is necessary. Scientists quantified the land's contribution to global emissions by analyzing data collected by the Japanese Space Agency's Greenhouse Gases Observing Satellite and NASA's Orbiting Carbon Observatory. Researchers compared the sat...
