Nasa found evidence of alien life in the 1970s, according to a former senior scientist – and ignored it. The Viking landers were sent to the Martian surface more than 40 years ago, with the aim of exploring the planet. They included an experiment known as Labeled Release, or LR, which was intended to look for signs of life on the planet.

A Milwaukee County Park has a new name. Columbus Park is now Indigenous Peoples' Park. The new signage was unveiled Monday morning, and it's all part of a bigger movement nationwide to dismantle Columbus Day and replace it with Indigenous Peoples' Day.

California's Tehachapi Pass is already home to one of the largest wind farms in the world, and now Amazon is coming, building a huge wind project in the area. How renewable-energy projects from tech giants are changing life in small-town America.

‘We’re documenting destruction of world’s most beautiful ecosystems, it’s impossible to be detached’

The mass extinction event that killed the dinosaurs led to the world’s oceans being disrupted for millions of years, according to new research. Scientists who examined fossil records spanning 13 million years found that global species of plankton at the base of the ocean ecosystem were disrupted for 2 million years after a massive asteroid strike on Earth.

With House Speaker Nancy Pelosi finally announcing an impeachment inquiry for Donald Trump, whistleblowers are currently the talk of the nation. While we all should be thanking the brave individual who disclosed that Trump was pressuring Ukranian officials to interfere in the upcoming 2020 election, we would be remiss if we didn’t discuss the treatment of Chelsea Manning, a trans woman who is still imprisoned for information she made public.

North America's birds are disappearing from the skies at a rate that's shocking even to ornithologists. Since the 1970s, the continent has lost 3 billion birds, nearly 30% of the total, and even common birds such as sparrows and blackbirds are in decline, U.S. and Canadian researchers report this week online in Science. "It's staggering," says first author Ken Rosenberg, a conservation scientist at the Cornell University Laboratory of Ornithology.

In the enterprise IT market, eliminating variables is an essential part of the job when it comes to troubleshooting. The more variables you have, the more opportunities you have for things to go wrong. By eliminating variables on your network and with your end-user devices, you make it easier to troubleshoot when issues arise. Variables especially cause issues when it comes to major OS upgrades as you have more testing to do.

In the most extreme regions of the universe, galaxies are being killed. Their star formation is being shut down and astronomers want to know why. The first ever Canadian-led large project on one of the world’s leading telescopes is hoping to do just that. The new program, called the Virgo Environment Traced in Carbon Monoxide survey (VERTICO), is investigating, in brilliant detail, how galaxies are killed by their environment.

On September 20, 1989, Apple product chief Jean-Louis Gassée stood on a stage in Universal City, California, and unveiled a new computer, the Macintosh Portable. It was Apple’s first battery-powered Mac, and the goal, Gassée declared, was to build a portable Mac that was every bit as powerful and usable as the familiar desktop models: “No subset of applications, no Mac Jr., no compromise.”

Back in 2017, we broke a story about how Google will delete all Android backups from devices that haven’t been used in two months. This report still remains true, but with the help of an eagle-eyed reader (thanks, John!), we now know that despite additional features, Android backups for paying Google One customers are also at risk.

It’s getting easier and easier to use AI to generate convincing-looking, yet entirely fake, pictures of people. Now, one company wants to find a use for these photos, by offering a resource of 100,000 AI-generated faces to anyone that can use them — royalty free. Many of the images look fake but others are difficult to distinguish from images licensed by stock photo companies.

What can we learn from other countries to help our retirees? The United States could learn quite a bit from other countries around the world when it comes to retirement security, according to a new report.

The smart TVs in our homes are leaking sensitive user data to companies including Netflix, Google and Facebook even when some devices are idle, according to two large-scale analyses. Researchers from Northeastern University and Imperial College London found that a number of smart TVs, including those made by Samsung and LG, and the streaming dongles Roku and Amazon’s FireTV were sending out data such as location and IP address to Netflix and third-party advertisers.

U.S. homebuilding surged to more than a 12-year high in August as both single- and multi-family housing construction increased, suggesting that lower mortgage rates were finally providing a boost to the struggling housing market. Housing starts jumped 12.3% to a seasonally adjusted annual rate of 1.364 million units last month, the highest level since June 2007, the Commerce Department said on Wednesday.

The ozone hole over Antarctica this year could be one of the smallest seen in three decades, say scientists. Observations of the gas's depletion high in the atmosphere demonstrate that it hasn't opened up in 2019 in the way it normally does.

The Trump administration has authorized a Florida man to bring back the “skin, skull, teeth and claws” of a lion he hunted in Tanzania, granting the first permit to import a lion from that country since the species gained protection under the US Endangered Species Act.
