As the investigation continues into why a female shooter opened fire at YouTube headquarters, data show that it's rare for women to carry out such shootings -- making Tuesday's incident unusual.The shooting unfolded at the San Bruno, California, company premises when a woman shot and injured three people, and then apparently took her own life, officials said.She appeared to have killed herself with a handgun, San Bruno Police Chief Ed Barberini said. The woman has been identified as Nasim Najafi Aghdam, a 39-year-old from San Diego, California. 558

Astronomers looking at the atmosphere in neighboring Venus see something that might just be a sign of life.In a study published Monday, researchers from Cardiff University, MIT and elsewhere say they found the chemical signature of a noxious gas called phosphine.On Earth, phosphine is associated with life. It's found at the bottom of ponds, in badger guts and in penguin guano.Venus’ phosphine was observed in a narrow, temperate band within the planet’s atmospheres, where temperatures range from 30 to 200 degrees Fahrenheit. Scientists have speculated that if life exists on Venus, this layer of the atmosphere, or cloud deck, is likely the only place where it would survive, according to MIT.“This phosphine signal is perfectly positioned where others have conjectured the area could be habitable,” said the study’s co-author and EAPS Research Scientist Janusz Petkowski.Astronomers tried to figure out other, non-biological ways it could be produced and came up empty.“It’s very hard to prove a negative,” said Clara Sousa-Silva, research scientist in MIT’s Department of Earth, Atmospheric and Planetary Sciences (EAPS). “Now, astronomers will think of all the ways to justify phosphine without life, and I welcome that. Please do, because we are at the end of our possibilities to show abiotic processes that can make phosphine.”Outside experts — and the study authors themselves — say the research is tantalizing but not yet convincing. 1454

As the world waits for deliveries of Pfizer’s coronavirus vaccine, the pharmaceutical company is having to adjust their target after hitting supply chain obstacles, according to the Wall Street Journal.“Scaling up the raw material supply chain took longer than expected,” a company spokeswoman told the WSJ.Pfizer and partner BioNTech SE had hoped to ship out 100 million doses of their vaccine by the end of the year, that has now reportedly been cut to estimates of about 50 million.Two doses are needed for each person to be vaccinated.Pfizer did not elaborate on where the raw material shortfalls happened. They did say some raw materials in early production earlier this year did not meet their standards and they had to fix the issue.After the WSJ’s report, Pfizer’s stock price dropped and the S&P 500 fell slightly.The United Kingdom has granted emergency use of the Pfizer vaccine, and is expected to start administering doses soon. The FDA in the U.S. is considering a similar authorization, which could come later in December.As part of Operation Warp Speed, the U.S. Government has purchased 100 million doses of Pfizer’s vaccine, with an option to buy more.Roughly 20 million of those doses were expected by the end of the year once the FDA granted emergency use authorization. No word on how Pfizer’s shipping delays could impact this number.Pfizer says their production lines in the U.S. and Europe are complete and they are “confident” they will supply the targeted number of doses in early 2021. 1524

As millions of Americans are struggling to find work, some have stopped looking and decided to create an opportunity for themselves instead.Experts believe this is evident in the sudden spike of new business applications.For example, a few months ago, Leigh Altshuler in New York City lost her job and rather than search for a new one, she decided to invest her entire savings into a business around her passion for books.“I was caught definitely by surprise,” said Altshuler. “I felt so low when I lost my job and to be able to turn this into something that makes me feel so lucky and so fortunate, is already a huge success.”Altshuler’s bookstore, Sweet Pickle Books, is expected to open by the end of October.Nicolas Bryon took a similar path.“I was working at a local restaurant here in Tampa when the pandemic hit,” said Bryon. “I was a forced layoff."Bryon and his brother recently opened a meal kit business around the chef’s homemade pasta. Starting a business together was an idea they had kicked around for years, but never had the time to flesh it out. That is, until Bryon lost his job.“Definitely had the time to slow things down and plan things out,” added Bryon.The business has taken off, providing more than a good income for the siblings.“I feel free,” he explained. "I feel a lot freer than I did a few months ago. Doing what I love, like on my own time, creating my own dishes and being financially sustained. It’s awesome.”According to data provided by the U.S. Census Bureau, across the country, there have been at least 3.2 million new business applications filed this year. This time last year, that number was around 2.7 million.“It is hard to know at the moment as to whether or not this trend that we have seen, that is very discernible, is going to continue and it is hard to know exactly what the real impact over time is going to be,” said John Dearie, founder of the Center for American Entrepreneurship in Washington, D.C.Dearie believes new businesses like Sweet Pickle Books and Pasta Packs have an uphill battle. However, if these businesses and other new ones survive, they could be a major factor in our economic recovery.“Startups are disproportionately responsible, they are not the only source, but they are the major source, but disproportionately responsible for the innovations that drive economic growth and job creation in the economy,” explained Dearie.For now, they are helping at least three people survive and find purpose in this pandemic. 2497
