Liquid water runs down canyons and crater walls over the summer months on Mars, according to researchers who say the discovery raises the chances of being home to some form of life.
The trickles leave long, dark stains on the Martian terrain that can reach hundreds of metres downhill in the warmer months, before they dry up in the autumn as surface temperatures drop.

Giant Viruses Are Hiding in Permafrost, But Not for Long
If you’re a germophobe, you won’t find comfort even in bleak Siberian expanses. Scientists have made another massive discovery of ancient (and giant) viruses hidden dormant in the permafrost. As the planet warms, finding these things—and waking them—is going to become more commonplace.
That’s significant, especially when you understand the gravity of the findings for experts involved in the ongoing research.
Two drugs proven more effective than standard kidney cancer treatment
A pair of drugs have overshadowed the use of standard therapies after new clinical trials suggest they work better for advanced kidney cancer.
The two treatments -- nivolumab and cabozantinib -- each successfully prolonged the survival of renal-cell cancer patients during separate studies both published in the New England Journal of Medicine.
Mormon church issues call for calm as 'blood moon' sparks apocalypse fears
A rare confluence of a lunar eclipse and a supermoon to happen this weekend has prompted such widespread fear of an impending apocalypse that the Mormon church was compelled to issue a statement cautioning the faithful to not get caught up in speculation about a major calamity.
Sunday night’s “blood moon” and recent natural disasters and political unrest around the world have led to a rise in sales at emergency-preparedness retailers.
Drinking water systems imperiled by failing infrastructure
Deep inside a 70-year-old water-treatment plant, drinking water for Iowa's capital city is cleansed of harmful nitrates that come from the state's famously rich farmland.
Without Des Moines Water Works, the central Iowa region of 500,000 people that it serves wouldn't have a thriving economy. But after decades of ceaseless service, the utility is confronting an array of problems: Water mains are cracking open hundreds of times every year. Rivers that provide its source water are increasingly polluted. And the city doesn't know how it will afford a $150 million treatment plant at a time when revenues are down and maintenance costs are up.
Is the GOP Clown Car a Volkswagen? It should be.
China marked its President's visit to the US by announcing a cap and trade program on the burning of carbon starting in 2017. Now the Right Wing Nut Jobs really can call Obama's Cap and Trade proposal a Commie Plot with some small measure of truth.
China's economic problems are likely to get somewhat worse, but it's hardly the global disaster the short sellers would like you to bet on. Literally bet on, Wall Street has instruments to sell you that will cover you against China's collapse for a small fee. Check out their Brooklyn Bridge penny stocks while you're at it.
Supermassive black hole bigger than scientists thought was possible
Astronomers in England have discovered a supermassive black hole many times larger than should be possible.
In astrophysics, very few rules are hard and fast. There are mostly just loose parameters, theories and informed expectations -- expectations that are constantly being subverted by newly discovered phenomena.
FDA: Start-up's cancer blood test may be harmful
A San Diego company selling an early cancer detection test was notified by the U.S. Food and Drug Administration it can find no evidence the test actually works, and is concerned it could prove to be harmful for some people.
Pathway Genomics debuted its CancerIntercept test in early September with claims it can detect cancer cell DNA in the blood, picking up mutations linked to as many as 10 different cancers. The goal is to catch cancer early in people who are "otherwise healthy" and not showing symptoms of the disease.
Brain-computer connection helps paralyzed man walk
A man's ability to walk using direct brain control of his legs was restored after years of being paralyzed, researchers reported in a proof-of-concept study.
The system uses electrical signals from the man's brain, sending them to electrodes placed on his knees, allowing him to voluntarily move his legs.
Previous research has shown paralysis patients can be made to move their legs with noninvasive treatments, however this study used virtual reality training and a harness system, rather than an exoskeleton to help the man support his weight.
