Understanding when and how neurons die is an important part of research on neurodegenerative diseases like Lou Gehrig’s, Alzheimer’s and Parkinson’s diseases.
Winters are getting warmer, yet Bostonians were digging out from nearly 2 feet of snow from a historic blizzard in late January. Why is the Northeast seeing more big snowstorms like this?
Federal and state governments are turning to a facial recognition company to ensure that people accessing services are who they say they are. The move promises to cut down on fraud, but at what cost?
The lack of large numbers of fossils makes it hard to study sexual dimorphism in dinosaurs. But a new statistical approach offers insight into this question and others across science.
Many people with epilepsy are unable to remember what happened immediately before they have a seizure. This may be because seizures and memory use the same pathways of the brain.
Blood plays a vital role in keeping us alive, from delivering oxygen to the body’s organs to fighting off infections.
With about 200 orbital launches scheduled and ambitious missions on everything from lunar bases to the search for life in the works, there’s a lot to watch in 2022. An astronomer explains the highlights.
Unlike humans, many animals are able to regenerate their limbs after losing them. Giving the body the right conditions for regrowth might allow people to recover lost limbs as well.
Months not eating or moving don’t result in muscle wasting and loss of function for animals that hibernate. New research found gut microbes help their hosts hold onto and use nitrogen to build proteins.
It’s hard to get accurate measurements, but a nationwide network of more than 8,000 volunteers with rulers and specific standards reports after every storm.
Russia probably has the means to attack US electrical grids and otherwise create havoc but probably won’t go that far. Instead, watch for disinformation aimed at undermining the US and NATO.
None of our authors can see the future, but many do have expertise that offers insights about what’s reasonable to expect.
The CDC’s updated mask guidelines say that cloth masks offer the least protection from COVID-19. Differences in the materials masks are made from and the ways they fit are the reason.
Airplanes use radio waves to determine how far off the ground they are. New 5G cellphone services come close to the same frequencies the airplanes use. Here’s how that can be a problem.
Understanding how the brain translates smells into behavior change can help advance search and rescue technology and treatments for neurological conditions.
DNA and mRNA vaccines produce a different kind of immune response than traditional vaccines, allowing researchers to tackle some previously unsolvable problems in medicine.
By shutting off internet access completely, the government of Kazakhstan was able to silence dissent, hinder protesters’ coordination and keep the populace in the dark.
How did penguins end up with so few bones – and become lightning-fast swimmers?
The proportion of women in a discipline influences how rigorous and trustworthy people rate the field overall, as well as whether they categorize a STEM field as a ‘hard’ or ‘soft’ science.
A phenomenon first theorized over 200 years ago is also a telltale sign of nuclear tests.
The US has made a dent in Russian cyber criminal gangs. But tensions with Russia and the shadowy nature of hacking keep the threat level high.
Compared to people who aren’t as good at math, people who are better at math are more happy when they have high incomes and less happy when they have lower incomes.
Opioids can cause death by slowing breathing to dangerously low levels, or stopping it altogether. Examining one area of the brain may eventually lead to safer painkillers.
When researchers look at CCTV footage of how people really react during earthquakes – as opposed to what they report after the fact – it looks like alerts aren’t yet inspiring protective action.
