It might be life, or it might not be. But the good news is that we now have evidence of some sort of activity under the surface of Mars -- phenomena subject to solid, repeatable measurement.
The aging brain goes through predictable changes, and as a result, old age is usually accompanied by some cognitive decline, even dementia. Happily, some of the risk factors for mental aging are open to intervention.
Alan Turing and his legacy are pivotal reminders of the limitations of data analysis without the context. How would he be evaluated today looking only at some of those metrics? He published just a few articles in his too short life, but Turing's work has had profound impact upon computer science that still resonates.
NASA's Curiosity rover detected a burp of methane on Mars lasting for several months--possibly stemming from a geologic process called serpentinization, or possibly the signature of microscopic Martian life.
NASA's successful launch of the Orion spacecraft was an important step, but it is only like dipping a toe in the cosmic ocean. In fact, the future of U.S. space leadership is being starved by lack of funding. Continued neglect will harm our national security, and our economy.
We have this conundrum of who has a soul and who goes to heaven because the basic premise on the question is rather absurd. The concept of a soul is fatally flawed, just as is the idea of dualism.
Before I ate my sandwich, I removed a little pill bottle from my bag, shook two of the white oblong pills into my hand, and popped them into my mouth. I spat them back out. Something wasn't right.
If you are a planetary scientist, you are having one of your best years... ever! Beyond the drama of the images, the technology that makes them possible is also amazing. How could anyone NOT be excited by the exploration of our solar system? Who needs the distant stars... for now.
Plants harvest carbon dioxide from the air, and when we dump fossil fuel carbon into the atmosphere much of it runs through the world's food chains and into our bodies. You build most of your body from air and water, but to do this you need the help of plants.
These days, with scientific knowledge proliferating so rapidly and in such a seemingly undifferentiated torrent, how can one hope to mark the genesis of new areas of specialized investigation?
I agree that it is crucial to attend to the psychological and emotional meaning of all experiences and understand the social context in which they occur. But I do worry that the report creates its own set of unintended problems and may inadvertently perpetuate rather than dispel confusion and stigma, especially for those who have the most severely impairing of psychotic experiences.
It's perfect, sublime, and might even be the prime day for doing something out of the ordinary.
Money and deals are flowing into companies that promise to edit genes. Human, animal, plant, all kinds of DNA may be on the cutting board. And once the replacements are pasted in, the results could dramatically change our lives -- for better or for worse.
America is leading the world in scientific discoveries and technological advances, and key to that is the independence of the scientific process that has served American innovation so well in the past. It's essential to protect that process and ensure that scientific merit is determined by scientific peers.
Dark matter continues to live up to its name. The most recent results from the European Space Agency's Planck spacecraft appear to cast serious doubt on previous claims of potential detections of the elusive dark matter particles.
With the current news cycle highlighting police brutality against African Americans, it is hard not to contemplate the continuing role of race in American life. Despite our progress as a nation and more broadly as a human race, we still struggle with seemingly antiquated modes of thinking that lead to unnecessary frictions between people.
My son turns 21 this Saturday, and I think that he's really happy that he'll be able to go to a bar this Friday night at 12:01 (when it's officially Saturday) and order his first alcoholic beverage legally with his real ID. But I am going to be happier.
The fact that smiling is basically required when clearly enunciating a word that ends with the hard E sound is worth consideration beyond one-time photo shoots.
Obstacles to this basic need to roam, such as human development, can provide formidable threats to long-term survival of many species. For the large carnivores, it's not just about losing the freedom to move, it's about losing a natural process.
