A small cadre of psychological scientists have continued over the years to explore the controversial connection between low intelligence and prejudice, and at this point they have overcome most of the methodological barricades, allowing them to rigorously analyze and answer this important societal question.
A number of proposals and perspectives have emerged that, taken together, paint a compelling and converging picture of why sleep evolved and why it is now needed.
If the type of telescope described here can be built, then the tyranny of distance is vanquished. You can forget deep space probes and their long travel times. We could explore alien worlds in the comfort of our own homes, as our laptops scroll and zoom through data sets collected by a mammoth, space-based telescope array.
This simple blood test for the prediction of suicide risks not only lacks a proper scientific basis but signifies unacceptable ignorance of the motives behind suicide thoughts and suicide attempts. Because of the complex nature of suicide, it is unlikely that a genetic test will ever be the key to prevention.
It is a given in science that results should be reproducible. That's why authors are required to provide detailed experimental methods, and must agree to share unique reagents, cell lines, or software tools with researchers.
When Ebola drugs and vaccines become available, trust -- engendered best by knowledgeable local leaders - may be the vital ingredient in ensuring that drugs are distributed most quickly to those in need.
Seven days; lots of science in the news. Here's our roundup of this week's most notable and quotable items.
I realized how easily we immerse ourselves in our own disciplines and envelop ourselves in our own values, and that exiting these self-imposed and limiting confines is key to understanding and propelling ourselves toward any future -- especially the one we humans envision on Mars.
Until astronomers detect signs of life on Earth-like plants around Sun-like stars, or until SETI searches record an old TV show broadcast by a civilization circling another star, we will have to be satisfied with these tiny, fluffy space aliens.
Not surprisingly, the record of the first humans identified by a personal name goes back to before the dawn of history itself. Through his artistic "Love Symbol", the The Artist Formerly Known as Prince gave us a clue how pre-writing names were probably rendered!
We should not be reluctant to embrace the one word that has always encompassed everything that we do: botany, the study of plants. Our work is critical to the health of the planet and the ages-old quest to better understand it. Our skills, our talents, and our passion are needed now more than ever.
"Diogenes," the lie-catching machine in the sci-fi screenplay that a friend and I wrote 20 years ago, made no mistakes. In real life we aren't quite there yet, but our recent research on truth and falsehood is getting closer than I ever expected it would.
You can go ahead and try to measure the speed of light in a vacuum if you like. If your measuring instruments are properly calibrated by an atomic clock, then you are going to get 299,792,458 meters per second every time.
As I looked over the bios provided on NRC's webpage, I quickly realized that the Council appears to have a pretty poor idea of how to carry out such a challenging, complex and multifaceted study. In fact, this week 67 scientists and researchers publicly rebuked the NRC for failing, right at the outset, to put together a slate of experts equipped for the task.
I love Mars rovers and cool space stations as much as any baby boomer, but the harsh reality is that America cannot afford a space program whose mission is to boost national prestige or serve as a white-collar jobs program. To justify its existence NASA must drive the private sector forward in space, not the other way round.
When scientists publish an analysis of the impacts of climate change on species, ecosystems and people, the language used can sound terribly distant and cold. In truth, the tone of these studies reflects the tone of science but not the feelings of scientists.
After a visit to one of these destinations, they'll return to school knowing that learning can be fun. Apparently, if you hide education behind a cloak of fun (dinosaurs, astronauts, dolphins and observatories), they will love it.
North America has beavers. Europe and Asia have beavers. Britain should have them too, but we killed the last one a few centuries ago. But now they have turned up on a river in southern England. No one knows how they got there, but the official reaction is that they must be captured.
The notoriety of the Tuskegee syphilis study is unparalleled in the field of bioethics. Last week marked the 42nd anniversary of the horrific experiment's termination, and many people took the opportunity to recall Tuskegee and examine its relevance to the treatment of human research subjects today.
