San Francisco, April 1 Google’s email service Gmail that has nearly 1.5 billion monthly active users turned 15 on Monday. Created by Paul Buchheit on April 1, 2004, Gmail started with an initial storage capacity of one gigabyte per user. Today, Gmail allows 15 GB free storage. Users can receive emails up to 50 MB in size, including attachments, while they can send emails up to 25 MB in size. In order to send larger files, users can insert files from Google Drive into the message. “Yahoo Mail has 228 million users a month. Little by little, Gmail displaced incumbents like AOL Mail and Hotmail,” reports CNET. It’s still a free product for consumers but Gmail has now become a paid suite of enterprise products, including presentation and word processing software. A year after Gmail, the company launched Google Maps which is now the leading map service on the web. Google also bought Android and YouTube, the biggest mobile operating system and video-sharing site. The company built t

You can now perform supercomputer simulations of the heart's electrophysiology in real time on desktop computers and even cellphones.

Although organ failure can be fatal, your kidneys, heart, and liver are prepared for this catastrophe. Emerging research supports the finding that two cell populations quickly respond and work together to restore a non-functioning, or failing, organ. First, the surviving cells go into overdrive, working to keep the organ functioning while stem-like cells replace damaged tissue. A Review explores how this dual-response can save lives. from Latest Science News -- ScienceDaily https://ift.tt/2V83F0f

Researchers have designed two types of nano-sized building blocks that can automatically connect into cubes and scramble back into individual components based on the temperature of their environment. This accomplishment is another step towards chemical systems that more realistically mimic life. 'Imagine mixing two liquids together, like ink and water. They will automatically do the simple chemical process of dispersing until they are perfectly mixed,' said Professor Shuichi Hiraoka of the University of Tokyo. from Latest Science News -- ScienceDaily https://ift.tt/2I2SNgb

Getting big molecules into cells isn't easy, and it isn't easy on the cells, either. Bulk electroporation blows holes throughout the cell and can kill many of them. Viruses like AAV have limited capacity for macromolecules like Cas9, and lentivirus has safety issues. A new, gentler form of electroporation, called nanoEP, causes less trauma to cells and is more efficient, potentially boosting delivery of large molecules for gene editing or CAR T-cell immunotherapy. from Latest Science News -- ScienceDaily https://ift.tt/2I3kyFB

WASHINGTON NASA's Mars Helicopter, designed to fly in thin atmosphere and low gravity, has successfully completed flight tests and is prepared for its journey to the Red Planet scheduled to take off in 2020, the US space agency said. Weighing in at no more than 1.8 kilograms, the helicopter is a technology demonstration project currently going through the rigorous verification process certifying it for Mars. The majority of the testing the flight model is going through had to do with demonstrating how it can operate on Mars, including how it performs at Mars-like temperatures, NASA said in a statement.  The helicopter has to function in extremely cold temperatures, including nights with temperatures as low as minus 90 degrees Celsius. The helicopter is scheduled to reach the surface of the Red Planet in February 2021, when the firmly nestled under the belly of the Mars 2020 rover.  A few months later, it will be deployed and test flights will begin—the first from the surface

LONDON The sun's magnetic field is 10 times stronger than previously believed, finds a study which can potentially change understanding of the processes that happen in the sun's immediate atmosphere. The study found that the sun's corona extends millions of kilometres above the surface, measuring 1,400,000 kilometres across—109 times larger than Earth—and 150,000,000 km from Earth. "Everything that happens in the sun's outer atmosphere is dominated by the magnetic field, but we have very few measurements of its strength and spatial characteristics," David Kuridze, research student at the Aberystwyth University. Using the Swedish 1-m Solar Telescope at Roque de los Muchachos Observatory, La Palma, in the Canary Islands, Kuridze studied a particularly strong solar flare which erupted near the surface of the sun on 10 September 2017. Solar flares appear as bright flashes and occur when magnetic energy that has built up in the solar atmosphere is suddenly rel

LONDON April Fools hoax stories could offer linguistic clues to spotting 'fake news' articles, say scientists who identified the similarities in the language used in humorous spoofs and malicious stories. Researchers from Lancaster University in the UK compiled a dataset of more than 500 April Fools articles sourced from more than 370 websites and written over 14 years. They found that there are similarities in the written structure of humorous April Fools hoaxes published by media outlets and fake news stories. "April Fools hoaxes are very useful because they provide us with a verifiable body of deceptive texts that give us an opportunity to find out about the linguistic techniques used when an author writes something fictitious disguised as a factual account," said Edward Dearden from Lancaster University. "By looking at the language used in April Fools and comparing them with fake news stories we can get a better picture of the kinds of language used by a

LONDON Over 674 million Indians are likely to breathe highly polluted air in 2030, even if the country were to comply with its existing pollution control policies and regulations, according to a study. The study, released by the International Institute for Applied Systems Analysis (IIASA) in Austria and the Council on Energy, Environment, and Water (CEEW) in New Delhi, shows that only about 833 million citizens would be living in areas that meet the National Ambient Air Quality Standards (NAAQS) in 2030.  Indian citizens are likely to breathe air with high concentrations of PM2.5 in 2030, even if India were to comply with its existing pollution control policies and regulations, the report said. The study also found that the Indo-Gangetic plain, covering parts of states such as Punjab, Haryana, Uttar Pradesh, Bihar, and West Bengal, has the highest population exposure to significant PM2.5 concentrations.  This is mainly due to the high density of polluting sources and reduced venti

NEW DELHI Searching for a life partner on matrimony sites has become hi-tech now, as the marriage portals are taking the help of artificial intelligence to find and recommend a life partner for their users.

Researchers found high concentrations of mercury, arsenic, and lead, in blood samples obtained from Great white sharks in South Africa. The samples had levels that would be considered toxic to many animals. However, the study found no apparent negative consequences of these heavy metals on several health parameters measured in the sharks, including body condition, total leukocytes, and granulocyte to lymphocyte ratios, suggesting no adverse effects on their immune system. from Phys.org - latest science and technology news stories https://ift.tt/2WwqFWU
