Women who get frequent headaches or migraines are more likely than others to have sexual problems, a new study from Italy says.
The results show that more than 90 percent of women seeking medical treatment for their headaches had significant impairments of their sexual function, and 29 percent reported being distressed over their sex life.
"Women referred for severe head pain report a high rate of sexual symptoms and sexual distress,"

Giant DiscoveryIn southern Argentina, scientists discovered the remains of seven adult dinosaurs that lived 95 million years ago. The huge beasts belong to a family known as the titanosaurs. They may be the biggest dinosaurs to have ever roamed Earth.
Huge beastThe newfound dinosaur would have towered over carnivores like beasts in the Tyrannotitan genus, as well as giraffes and humans, as this diagram shows.
Heavy Duty JobUsing jackhammers, shovels and even bulldozers, researchers from the Museum of Paleontology Egidio Feruglio in Argentina's Patagonia region removed the fossils from a site in the center of the Chubut province, about 160 (260 kilometers) from the city of Trelew.

Ghost-like particles called neutrinos hardly ever interact with normal matter, giving the teensy apparitions supreme hiding powers. They are so elusive that, in the decades since their initial discovery, physicists still haven't pinned down their mass. But recently, by plopping them onto a 200-ton "neutrino scale," scientists have put a new limit on the neutrino's mass.
The result: It's very, very small.
With the world's most sensitive neutrino scale, physicists analyzed a flood of data to determine that the elusive particle is no heftier than 0.

Here's a mysterious truth that scientists have known since 1983: Protons and neutrons act differently when they're inside an atom, versus floating freely through space. Specifically, the subatomic particles that make up those protons and neutrons, called quarks, slow down massively once they're confined to a nucleus in an atom.
Physicists really didn't like this, because neutrons are neutrons whether they're inside an atom or not. And protons are protons. Both protons and neutrons (which together make up the class of particles called "

Snooty, the oldest manatee in captivity, died Saturday (July 22) at age 69, after an accident at the South Florida Museum in Bradenton, Florida.
A morning visual check by museum staff revealed that Snooty was missing, and he was later discovered caught in a duct behind the tank he shared with three young manatees, Jeff Rodgers, the museum's provost and chief operating officer, said at a news briefing in Bradenton yesterday (July 23).

A new blood test approved by the U.S. Food and Drug Administration to detect brain injuries might reduce the number of potentially unnecessary brain scans, according to a new study.
Traumatic brain injuries (TBIs) — which can range from relatively mild conditions (such as a concussion) to severe ones (such as bleeding in the brain) — can be difficult to diagnose. One way to diagnose the injuries is a CT scan, but these imaging tests can be very costly and expose patients to radiation.

In a search for genes that fight off aging, researchers have now charted the bowhead whale genome.
Bowheads are filter feeders found only in the Arctic, and are some of the largest mammals on Earth. Old harpoon points found in bowheads suggest the whales live for some 200 years.
The scientists' search turned up several interesting genetic targets worthy of further study, said senior study author Joao Pedro de Magalhaes, a biologist and expert in aging science at the University of Liverpool in the United Kingdom.

A lost piece of one of Stonehenge's iconic standing stones has finally been returned.
The cylindrical piece of stone was drilled out of the giant Neolithic standing stone and then taken as a souvenir more than 60 years ago.
The rediscovery means scientists will be able to study the chemical makeup of the largest stones at Stonehenge, in an effort to learn more about where they came from.
English Heritage, the cultural agency that oversees Stonehenge, said the piece was taken from a fallen "

Medically known as recurrent herpes labialis, cold sores or "fever blisters," are groups of painful, fluid-filled blisters that tend to cluster on or around the lips, though they can occasionally affect the tongue, gums and the hard and soft palate. Herpes Simplex Virus Type 1 (HSV-1) is the most common virus that causes cold sores and is usually acquired through direct contact with infected lesions or body fluids such as saliva.

A big bump to the head can literally send the brain bouncing around inside the skull, and all that jostling may injure the brain in a way that disrupts the flow of information from one half of the organ to the other, according to a new study.
The study focused on a dense bundle of nerve fibers known as the corpus callosum, which normally serve as a landine for the left and right hemispheres of the brain to talk to each other.
