What a Martian meteorite can teach us about Earth's origins      (via sciencedaily.com) 

What do Mars and Iceland have in common? These days, not so much. But more than 4.5 billion years ago, it's possible the Red Planet had a crust comparable to Iceland today. This discovery, hidden in the oldest martian fragments found on Earth, could provide information about our planet that was lost over billions of years of geological movement and could help explain why the Earth developed into a planet that sustains a broad diversity of life and Mars did not.

Space rocket junk could have deadly consequences unless governments act      (via sciencedaily.com)     Original source 

The re-entry of abandoned stages of rockets left in orbit from space launches have a six to 10 per cent chance of severely injuring or killing a human being in the next decade, according to a new study. Researchers say governments need to take collective action and mandate that rocket stages are guided safely back to Earth after their use, which could increase the cost of a launch, but potentially save lives.

Undead planets: The unusual conditions of the first exoplanet detection      (via sciencedaily.com) 

The first ever exoplanets were discovered 30 years ago around a rapidly rotating star, called a pulsar. Now, astronomers have revealed that these planets may be incredibly rare.

How stressed-out plants produce their own aspirin      (via sciencedaily.com) 

Plants protect themselves from environmental hazards like insects, drought and heat by producing salicylic acid, also known as aspirin. A new understanding of this process may help plants survive increasing stress caused by climate change.

Rare deep-sea brine pools discovered in Red Sea      (via sciencedaily.com) 

Researchers recently discovered rare deep-sea brine pools in the Gulf of Aqaba, a northern extension to the Red Sea. These salty underwater lakes hold secrets into the way oceans on Earth formed millions of years ago, and offer clues to life on other planets.

The best offense is a great defense for some carnivorous plants      (via sciencedaily.com) 

Insect-eating plants have fascinated biologists for more than a century, but how plants evolved the ability to capture and consume live prey has largely remained a mystery. Now,scientists have investigated the molecular basis of plant carnivory and found evidence that it evolved from mechanisms plants use to defend themselves.

X-rays help researchers piece together treasured cellular gateway      (via sciencedaily.com) 

After almost two decades of synchrotron experiments, scientists have captured a clear picture of a cell's nuclear pores, which are the doors and windows through which critical material in your body flows in and out of the cell's nucleus. These findings could lead to new treatments of certain cancers, autoimmune diseases and heart conditions.

The ultimate fate of a star shredded by a black hole      (via sciencedaily.com) 

In 2019, astronomers observed the nearest example to date of a star that was shredded, or 'spaghettified,' after approaching too close to a massive black hole. That tidal disruption of a sun-like star by a black hole 1 million times more massive than itself took place 215 million light years from Earth. Luckily, this was the first such event bright enough that astronomers could study the optical light from the stellar death, specifically the light's polarization, to learn more about what happened after the star was torn apart.

Electric vehicles pass the remote road test      (via sciencedaily.com) 

A new study, which demonstrates that even the most rural areas of Australia are feasible for electric vehicles, provides new hope for how the technology could be spread around the most secluded locations in other parts of the world. The study found the vast majority of residents, or 93 per cent, could travel to essential services with even the lower-range of electric vehicles currently available on the Australian market, without needing to recharge en route.

Porosity of the moon's crust reveals bombardment history      (via sciencedaily.com) 

Researchers find that, early in its history, the moon was highly porous, which was likely a result of early, massive impacts that shattered much of the crust. They reached their conclusions with simulations and data from NASA's GRAIL mission.
