Why have people around the world always been fascinated by vampires? Did vampire tales begin as a way to explain frightening phenomena actually witnessed? Although there is no scientific evidence for vampires, there is some scientific basis for vampire folklore.
Curing or even finding treatments for rare diseases is hard. Not necessarily because these diseases are any more complex than more common ones. It has more to do with the fact that there is very little profit to be made in helping people with these diseases.
Starting in 2014, California will require parents to see a health practitioner to learn the risks and benefits of vaccination before opting out of the state's immunization requirements. Public health officials hope that when parents learn the difference between science-based evidence and the uninformed myths so prevalent online and in the mainstream media, they'll decide to protect their children from the real risks of infectious disease, rather than worry about unfounded theoretical risks.
Sierra Nevada bighorn sheep are animals worth seeing. With their bright white rumps and the rams' remarkable headgear, they bound and leap over seemingly impassable alpine terrain. But you may have a tricky time spotting one–there are only about four hundred in existence.
In November, California voters need to decide whether or not GM foods should be labeled as such. They are making this decision even though a recent study shows that 49% of the people surveyed think that GM foods have genes whereas regular foods do not. Is this any way to run a democracy?
Every October, high-profile outlets from Ace Hardware to the NFL sell pink products to raise awareness and money for Breast Cancer Awareness Month. Critics of "pinkwashing" urge consumers to ask just how much of that money goes to support breast cancer programs–and challenge us to move beyond awareness to action.
Allison Bruce has a wonderful job: she spends all day making pictures for scientists. Bruce started out in science herself, earning a chemistry degree from UC Davis. After college, she worked in an environmental lab, but she didn't enjoy it and turned to art classes "to keep from losing my mind," she says.
Chemists want to reengineer metabolic proteins and pathways in microbes so they can convert sugar into commodity chemicals. Now a mutant protein found in cancer cells provides clues to help scientists improve a protein that could help microbes create a precursor to nylon. In science, as in so much of life, inspiration can come from unusual places.
Motion-activated cameras at Stanford University's Jasper Ridge Biological Preserve provide scientists a window into the secret lives of the animals there. This short video by the Stanford News Service reveals how these "camera traps" work and shows some of the amazing animals that roam around Jasper Ridge at night.
The first sniffles of flu season are upon us: a friend of mine was struck down, and couldn't join me in attending a science dialogue on Sunday night. This was darkly humorous, as the topic of the evening was pandemics.
New research is making us rethink how our DNA works – again.
As bizarre as black holes have been depicted in science fiction, the reality of black holes as described by science is far stranger.
Feral cats threaten native wildlife, from reptiles to birds, and often lead a miserable life. By better understanding the concerns of cat colony caretakers, wildlife biologists hope to find enough common ground to benefit both cats and wildlife.
