Ocean acidification could alter the behavior of fish and make them more anxious, a new study says.
The finding came in an experiment by researchers interested in the neurological effects of the shift in the chemistry of seawater that is happening as the ocean takes up carbon dioxide that has built up in the Earth’s atmosphere from human activity.
In a laboratory, scientists put one group of young rockfish, a common species along the California coast, in normal seawater and put another group of the fish in water with the lower pH the ocean is predicted to reach in about 100 years.
If you enjoy Pi Day (3/14) and Avogadro’s Number Day (6/22), then get this: today is a Pythagorean triple date.
You’d have to be a serious math nerd to recognize that the sum of the squares of 5 and 12 equals the square of 13. Which is exactly what the co-founders of the National Museum of Mathematics (MoMath) noticed.
So, along with some 2,000 fellow math geeks and museum staff, MoMath co-founder Cindy Lawrence will help surround the most well-known right-triangle-based edifice in the country -- New York’s Flatiron Building -- and execute a glow-stick proof of the ancient...
A massive planet found orbiting a star at a staggeringly great distance is smashing some long-held theories of planetary formation, researchers say.
The planet, according to a study published online Thursday in the Astrophysical Journal Letters, is unlike anything in our own solar system.
Eleven times more massive than Jupiter, planet HD 106906 b orbits a single sun-like star at a distance of 60 billion miles - about 650 times the distance Earth is from our own sun.
"This system is especially fascinating because no model of either planet or star formation fully explains what we see," said...
A class of oral diabetes medications that has drawn controversy in recent years reduces the risk of cancer in women taking it by almost a third, says a large new study conducted by researchers at the Cleveland Clinic.
In preventing cancer, the researchers found that insulin sensitizers, including the drugs metformin, rosiglitazone and pioglitazone (the latter two marketed as Avandia and Actos) were more powerful than insulin secretagogues such as glyburide, glipizide and glimepiride.
The effect was seen only in women taking the medications, not in men with Type 2 diabetes. And it was most...
There’s no place like home – especially for lemon sharks about to give birth.
Despite absences as long as 17 years, the pregnant sharks returned to the exact spot in the Bahamas where they were born when they were ready to become mothers, according to scientists who have been tracking the creatures since Bill Clinton was in the White House.
Researchers have long suspected that sharks returned to their birthplaces to give birth themselves – a phenomenon known as natal philopatry. Salmon do it. Species that take longer to mature, such as sea turtles, return to the general area...
Although they appear to be perfectly capable of taking care of themselves, the U.S. Fish and Wildlife Service is considering extending Endangered Species Act protection to 11 tarantula species native to India and Sri Lanka.
Sometimes known as parachute spiders, the colorful and fierce-looking arachnids are threatened by the international pet trade, where vividly hued spiders can fetch a few hundred dollars apiece. they are imperiled by shrinking habitats and fragmented ranges.
Should the tarantulas gain protected status here, U.S. officials could more easily prohibit their importation and...
Stop what you are doing and try saying this 10 times fast: "pad kid poured curd pulled cod."
Feeling tongue tied? You should. You just tried what might be one of the trickiest tongue twisters ever devised.
In a recent study, a research team found that "pad kid poured curd pulled cod" tripped up test subjects more than any other tongue twister they were asked to say. In fact, many people gave up on saying the phrase all together.
"If anyone can say this 10 times quickly, they get a prize," Stefanie Shattuck-Hufnagel, a psychologist at MIT, said in a statement.
Shattuck-Hufnagel and her...
A faulty connection between where the brain stores the auditory building blocks of language and where it processes them may be to blame for dyslexia, a new study suggests.
The findings represent the first neuroanatomical evidence that the vexing spelling and reading disorder striking people who otherwise can speak a language fluently lies in a connectivity problem in the brain's white matter, where nerve fibers relay electrochemical signals.
Various degrees of dyslexia strike about one in 10 people, making it difficult for them to analyze and assemble letter combinations and relate them to the...
Move over, "selfie." The Oxford English Dictionary may have let you into the official word club, but you’re still a lexical dilettante. The king of searched words this year, according to Merriam-Webster, is none other than "science."
The results from Merriam-Webster, based on 100 million lookups in its online dictionary per month, showed that "science" showed the highest increase in lookups compared to last year, 176%. Its definition: "knowledge about or study of the natural world based on facts learned through experiments and observation."
"It is a word that is connected to broad...
It may seem too small a space to house feelings so intense and complex, but the small walnut-shaped structure at the very core of our brain -- the amygdala -- serves as a kind of jewelry box in which we nurture and store our attachment to our mother. A new study peers into the workings of the amygdala in children who were adopted from orphanages abroad, and finds that for some, mother and stranger are not so far apart.
The study, conducted by researchers at UCLA on a group of children who experienced institutional care during their infancy, suggests that the absence of a mother's care results...
In a new study based on surveys of more than 1,300 government workers in Tennessee, black workers were less likely than white workers to say they felt supported by their coworkers. They also reported having fewer friends at work. And black workers in the study were more likely to report facing routine tasks and getting less autonomy on the job.
Yet the black workers surveyed were more likely than white workers to say they felt happiness and other positive emotions at work, the study said.
The results, published in Social Psychology Quarterly, surprised researchers, who had expected support at...
