Over 1,000 newly discovered asteroids hidden in the Hubble Archive
Researchers have found more than 1,700 asteroid contrails in archived Hubble data from the past 20 years. While many asteroids are already known, more than 1,000 are not. What are another 1,000 asteroids for? Like all asteroids, they could hold valuable clues to the history of the solar system. As time passes and more and […]

830 million year old potentially living organisms found trapped in ancient rock
An incredible discovery has just revealed a potential new source for understanding life on ancient Earth. A team of geologists has just discovered tiny remnants of prokaryotic and algal life – trapped inside halite crystals dating back 830 million years. Halite is sodium chloride, also known as rock salt, and the discovery suggests this naturally […]

Study of over 800 planet-forming disks reveals startling planetary evolution
Is our solar system comparable to other solar systems? What are the other systems like? We know from studies of exoplanets that many other systems have hot Jupiters, massive gas giants that orbit extremely close to their stars. Is this normal, and our solar system is the outlier? One way to address these questions is […]

A never-before-seen mimicry trick has just been recorded in Buzzing Bats
Scientists have discovered a clever mimicry trick used by some bats: they buzz like hornets when they think they are threatened by predators, giving the sonic impression that they are more dangerous than they are are actually. This is the first time behavior like this has been recorded in mammals, but it has happened elsewhere […]

For the first time, scientists have grown plants in lunar land. It didn’t go well
When the Artemis program returns humans to the Moon in (hopefully) a few years, there will be considerable logistics to sort out to keep such fragile beings alive in such a hostile environment. The question of food is not the least. Space agencies involved with the International Space Station are now very experienced in providing […]

There’s a major problem with the way we treat lab mice, and it could affect study results.
More than 120 million laboratory rats and mice are used worldwide each year. Many are accustomed to studying distressing conditions like cancer, arthritis and chronic pain, and almost all spend their lives in small, empty box-like cages: a kind of permanent confinement. Our new analysis shows that this restrictive artificial housing causes chronic stress in […]

Scientists Powered Basic Computer Just Algae For Over 6 Months
In a dreadful vision of a future cut off from the sun, the machine overloads into the Matrix film series turned to sleeping human bodies as sources of electricity. Had they had sunlight, seaweed would undoubtedly have been the best choice. Engineers at the University of Cambridge in the UK ran a microprocessor for more […]

This Record-Breaking “Gold Standard” Star Is Unlike Any We’ve Seen Before
What’s in a star? Well, if you’re a highly evolved specimen nearing the end of its life named HD 222925, that’s quite a lot, actually. Scientists conducted an analysis of this dark object and identified 65 distinct elements. This is the largest number of elements ever found in a single object outside the solar system, […]

Scientists have revived a glow of activity in human eyes after death
Scientists have momentarily restored a faint glow of life to dying cells in the human eye. In order to better understand how nerve cells succumb to a lack of oxygen, a team of American researchers measured the activity of mouse and human retinal cells shortly after death. Surprisingly, with a few adjustments to the tissue […]
