Scientist proposes a new timeline for Mars terrains
A Southwest Research Institute scientist has updated Mars chronology models to find that terrains shaped by ancient water activity on the planet's surface may be hundreds of millions of years older than previously thought. This new chronology for Mar.....»»
Fossil places extinct saber-toothed cat on Texas coast
Important scientific finds don't always come in the biggest, buzziest packages. Sometimes new discoveries come in little ugly rocks. Such is the case of a 6-centimeter-wide, nondescript mass of bone and teeth that helped a scientist at The University.....»»

Could Martian atmospheric samples teach us more about the red planet than surface samples?
NASA is actively working to return surface samples from Mars in the next few years, which they hope will help us better understand whether ancient life once existed on the red planet's surface billions of years ago. But what about atmospheric samples.....»»

On repeat: Biologists observe recurring evolutionary changes, over time, in stick insects
A long-standing debate among evolutionary scientists goes something like this: Does evolution happen in a predictable pattern or does it depend on chance events and contingency? That is, if you could turn back the clock, as celebrated scientist Steph.....»»
Desert locusts" jaws sharpen themselves, materials scientist discovers
Sharks lose teeth all their lives, replacing them in a kind of endless rotating Rolodex, while humans, of course, get only our two sets. Beavers' teeth, notoriously, grow all their lives and have to be worn down to prevent injury......»»
Why the Psyche spacecraft’s futuristic electric thrusters glow blue

Researchers propose use of electrical blackouts to determine impact of artificial light on wildlife
New research proposes the use of electrical blackouts, such as those experienced during loadshedding in South Africa, to enhance our understanding of how artificial light in urban areas may be affecting wildlife behaviors......»»
Personal crises reduce voter turnout, but may prompt other political action
Experiencing multiple life disruptions such as unemployment, eviction or a loss of health insurance makes people less likely to vote—but may motivate them to engage politically in other ways, a Cornell political scientist and co-authors report in n.....»»
New warp drive concept does twist space, doesn’t move us very fast

Astronomers determine Mars may face more potentially hazardous asteroids than Earth
A team of astronomers at Nanjing University has found evidence that Mars likely has more potentially hazardous asteroids in its path than Earth. In their study, posted on the arXiv preprint server, the group investigated the number of potentially haz.....»»
Exploring extremes in the search for life on Mars
People might assume the search for life on Mars ended when NASA's first rovers sent back images of the planet's barren, inhospitable surface. However, as scientists broaden their understanding of the extreme conditions in which life can flourish here.....»»
