What's Mars solar conjunction, and why does it matter?

The daily chatter between antennas here on Earth and those on NASA spacecraft at Mars is about to get much quieter for a few weeks.

Laser-produced uranium plasma evolves into more complex species

When energy is added to uranium under pressure, it creates a shock wave, and even a tiny sample will be vaporized like a small explosion. By using smaller, controlled explosions, physicists can test on a microscale in a safe ...

Breath! Respiring microbes generate more energy

How do cells generate and use energy? This question might seem simple, but the answer is far from simple. Furthermore, knowing how microbial cell factories consume energy and how proteins are allocated to do so is crucial ...

How memories form and fade

Why is it that you can remember the name of your childhood best friend that you haven't seen in years yet easily forget the name of a person you just met a moment ago? In other words, why are some memories stable over decades, ...

Brain's astrocytes play starring role in long-term memory

Star-shaped cells called astrocytes help the brain establish long-lasting memories, Salk researchers have discovered. The new work adds to a growing body of evidence that astrocytes, long considered to be merely supportive ...

Bioprinting complex living tissue in just a few seconds

Tissue engineers create artificial organs and tissues that can be used to develop and test new drugs, repair damaged tissue and even replace entire organs in the human body. However, current fabrication methods limit their ...

Study models new method to accelerate nanoparticles

In a new study, researchers at the University of Illinois and the Missouri University of Science and Technology modeled a method to manipulate nanoparticles as an alternative mode of propulsion for tiny spacecraft that require ...

The causes and risks of the Amazon fires

Fires have been breaking out at an unusual pace in Brazil this year, causing global alarm over deforestation in the Amazon region. The world's largest rainforest is often called the "lungs of the earth." Here's a look at ...

Scientists explore outback as testbed for Mars

This week, scientists from NASA's upcoming Mars 2020 mission joined their counterparts from the joint European-Russian ExoMars mission in an expedition to the Australian Outback, one of the most remote, arid regions on the ...

Why cursive handwriting needs to make a schoolcomeback

Teaching connected-style handwriting, otherwise known as cursive handwriting, has fallen out of fashion on many school curricula. Older generations have sometimes been shocked that some younger people today can't sign their ...

Geoengineering: 'Plan B' for the planet

Dismissed a decade ago as far-fetched and dangerous, schemes to tame global warming by engineering the climate have migrated from the margins of policy debates towards centre stage.

Caffeine does not influence stingless bees

The western honey bee (Apis mellifera) that has a sting for use in defense is common in Western Europe. Stingless bees, on the other hand, are mainly at home in the tropics and subtropics. They are a very social group and ...
