Science and Tech

peer review
Done properly, peer review requires that journals fulfill their role as knowledge custodians, rather than being mere knowledge distributors.
mars water
Water on Mars is key for human survival on the Red Planet, not just for drinking but for growing food and making fuel and oxygen.
placebo effect
The placebo effect is not the "power of positive thinking." The fact that it is getting stronger is not a good development.
When we satisfy our curiosity, the brain has a particular way of rewarding us.
If you put very fine black powder powder in a confined space it explodes in a cloud of heat, gas and noise.
earth axis move throughout year axial tilt
Even with leap years and long-term planning, our calendar won't be good forever. Here's why, and how to fix it.
multiverse a fortunate universe
A wild, compelling idea without a direct, practical test, the Multiverse is highly controversial. But its supporting pillars sure are stable.
A new “common-sense” approach to computer vision enables artificial intelligence that interprets scenes more accurately than other systems do.
In determining what qualifies as solid science, controversy is inevitable.
hypersonic flight
One day, we could fly across the U.S. in half an hour. A state-of-the-art hypersonic flight testing facility at UTSA could help make that dream a reality.
hot big bang
We know it couldn't have began from a singularity. So how small could it have been at the absolute minimum?
lab leak SARS-CoV-2
We don't know with 100% certainty where SARS-CoV-2 first came from or how it first infected humans. But not all options are equally likely.
life universe
Whether or not life exists elsewhere in the Universe, we can be assured of one thing: We are the only human beings in the cosmos.
battery
A century ago, electric cars were common. The fact that they were almost entirely replaced due to the internal combustion engine is a testament to the glacial pace of battery breakthroughs.
A drip in a hospital
The model is almost eight hours ahead of a doctor's recognition of a patient's deterioration.
James Webb Space Telescope
With launch, deployment, calibration, and science operations about to commence, here are 10 facts that are absolutely true.
photometry
The photometric filters for the Vera Rubin Observatory are complete and showcase why they are indispensable for astronomy.
steel tires
Steel tires may be better for the planet and could replace rubber.

The boiling new world, which zips around its star at ultraclose range, is among the lightest exoplanets found to date.
It's that time of year when the hours of meticulous wrapping of Christmas toys are viciously undone in seconds by tiny children.
humanoid robots
Humanoid robots are coming, and Ameca is designed to be the ideal platform to study human-robot interactions.
space sex
Whether NASA likes it or not, humans eventually will be having space sex.
An old man looking out of the blinds.
Americans have a lower life expectancy than people in other rich countries despite paying much more for healthcare. We explore the number of factors which might explain this difference.
∆G = ∆H - T∆S
∆G = ∆H - T∆S is one of the most abstract formulas in science, but it is also one of the most important. Without it, life cannot exist.
first contact
Life arose on Earth very early on. After a few billion years, here we are: intelligent and technologically advanced. Where's everyone else?
future of money
Digital currencies are set to upend paper currencies, but it likely won't be the decentralized utopia some hope it will be.
climate model
Driving Teslas and planting trees are nice, but methane reduction, industrial efficiency, carbon removal, and a moderate carbon tax are the most efficient ways to fight climate change.
Parker Solar Probe
How can you "touch the Sun" if you've always been inside the solar corona, yet will never reach the Sun's photosphere?
