It's an iconic image: a wrinkled great-grandmother hovering over a swollen belly while she dangles a needle on thread. "It's a boy" or "it's a girl," she'd proclaim without any real idea of what she's talking about. Scientists have long argued that there is no sure-fire way to determine an unborn child's gender. Even ultrasound can get it wrong. For lemurs, however, all it might take is a sniff of strong motherly BO.
"What goes around comes around," may be a common adage used by people, but new research has revealed that it's not a belief exclusive to humans. Rats, or at least ones in Norway, it seems, believe in doing favors when they are due as well, returning kindness shown to them by other rats in the past.
Cuba is facing a widespread and deadly epidemic of the Human Immunodeficiency Virus (HIV) that can progress into AIDS some three times faster than the most common strains of the virus. Now researchers have identified what makes this HIV different and deadlier than most.
Well... sort of. What we're really talking about here are the main components of those human vices - nicotine and caffeine - which are normally toxic to our tiny pollinator friends. However, much like some bird species that intentionally consume poisons to kill off intestinal parasites, small concentrations of these toxins could indeed help protect hives from illness
Bottlenose dolphins are iconic sea creatures, with thousands of vacationers flocking to the Mediterranean's clear waters to watch playful pods in action each year. Now, however, it has been revealed that these dolphins would not be found there thousands of years ago, making them relatively new settlers to the biblical "Great" or "Middle Sea."
For more than a decade, a vial of rare snake venom has been sitting in a lab while scientists stared it down, scratching their heads in wonder. Understanding how exactly a toxin works is a very important step in creating an antivenin (antivenom) for snake bites. However, in the case of rare coral snakes, how it caused severe seizures in its victims had remained an utter mystery, until now.
Mushrooms look like peaceful things, minding their own business as they soak up valuable nutrients from the soil around them. However, a rare few kinds of mushrooms are secret killers, lacerating, poisoning, or even strangling hidden prey as they innocently stand around. Now researchers have determined that one of these silent assassins gets the job done with nanoscopic "cookie cutters."
MmmMmm deep-fried ice cream; you ever have it? Cold creamy goodness wrapped in a warm flaky fried shell - the alliteration alone is enough to make my mouth water (what can I say? I'm a writer!) Now an expert at NASA is saying that while comets might not taste as good, they are just like the delicious dessert in terms of formation.
Most people know the popular saying "an elephant never forgets." Past studies have shown that some birds have pretty awesome memories too. But what about insects? Now, new research has revealed that a tiny wasp species in the remote tropical forest of Southeast Asia tells friend from foe by recognizing them visually.
The 9/11 terrorist attacks on the World Trade Center and the Pentagon were absolute tragedies, taking the lives of nearly 3,000 innocents that day. However, recent research has revealed that there was a silver lining to that incredibly dark storm cloud. Whales around American waters were reportedly far less stressed after the attacks, and now researchers are explaining why.
Handling insect specimens can be maddening work for experts, especially since one wrong move could fold wings or crumple delicate exoskeletons that were painstakingly collected over years of field surveys. Now entomologists are turning to an unusual means for safe observation: custom LEGO contraptions.
The massive 55 pound miracle seeds of the coco de mer palm are the stuff of legend. Now new research has determined that careful engineering and good "parenting" ensure these seeds grow to to such an impressive size.
If you've ever spent a few minutes perusing the internet aimlessly, you're bound to come across one of the web's most popular forms of entertainment: cute cat videos. And among those videos, a great many of them consist of cats and kittens playing in boxes. Now a new study offers clues as to why our feline friends love these cardboard hidey-holes so much.
Astronomers are shamelessly drooling over a new set of naked photos, but it's not exactly what you think. The photos, snapped from an ideal vantage point by the Cassini spacecraft, have managed to reveal that Saturn's moon Titan looks far more like the surfaces of Venus or Mars than experts expected, at least when it's stripped down to its birthday suit by buffeting solar winds.
The infamous invaders of kitchens, motel, and more, cockroaches have long been associated with filth and disgust. However, new research is associating them with personality as well, as they provide a strong example of individuality among insect populations.
