Clearing the Questions Around PTSD—How Researchers Revealed a New Genetic Link

MEDICINE & HEALTH It’s a story not too unfamiliar in the line of duty for those in the armed forces. When faced with the traumatic experiences, dangers and death of warring nations, often those on the front line are scathed to say the least. A new study revealing the origins and genetic markers for Post-traumatic stress disorder (PTSD) may provide a glimmer of hope for soldiers suffering with the condition, but with the stigma and disbelief the general public has regarding the disorder, the battle is far from over.

Catalina Fox Populations—From the Brink of Extinction to Potentially Off the List

Though the Catalina fox species may be the smallest species of fox in the world, it appears that size may not have anything to do with their survival. And while the animal may have been endangered decades ago, locals and visitors to the island of Santa Catalina are realized that their abundant numbers may be a sign of drastic change.

New Study Found No Link Between Mental Problems and Psychedelic Drugs

Despite what you may have been led to believe about the use of psychedelic drugs and your mental health, a new study from the Norwegian University for Science and Technology at Trondheim has found that the use of LSD and other psychedelic drugs is not associated with mental health problems.

NASA Seeks Talent with Space Apps Challenge

NASA has organized a new three-day event that will allow participants to develop mobile applications, software, hardware, data visualization and platform solutions that could contribute to the space exploration missions and improve life on Earth.

Climate Change Degrading Ancient Mummies

About 7 thousands years ago and predating the Egyptians by several thousands of years lived a tribe of people off the coast of Chile and southern Peru lived a tribe of people known today as "the Chinchorro". Like the ancient Egyptians, the Chinchorro used to mummify its dead, creating the oldest known mummies on Earth. But today, these mummies are now threatened by climate change.

SeaWorld Researchers Change the Conversation—Saving Stranded Sea Lion Pups

Though animal rights activists have questioned the capacity of the aquarium and the living situation of the performers, SeaWorld researchers and trainers are proving that the company’s main concern is the health and well-being of the animals. And with a new decision that has suspended sea lion and sea otter shows in the weeks to come, SeaWorld’s employees are taking a stance for what they know is right.

How ‘Gravitational Lensing’ Made One Supernova into Four—‘Einstein Cross’

Nicknamed the “Einstein Cross” after the famous physicist who predicted the possibility of the phenomenon as a result of his theory of relativity more than a century ago, the formation was made possible by a strange occurrence known as gravitational lensing. When a galaxy or cluster is large enough, they can often bend light that passes through it. And when they are rather perfectly aligned with Earth, even small events too far to be seen can be magnified so that researchers are able to detect them.

Oxygen May Boost Immune Cells Fighting Cancer

Researchers might have discovered another new weapon in the fight against cancer -- oxygen. In a new study in mice. researchers found that something as simple as breathing in extra oxygen might give immune cells the boost they need to attack cancer cells in the body.

Flu Only Infects Adults Twice a Decade

While the dangers of the flu may make headlines every flu season, researchers have calculated that adults over the age of 30 only catch the flu about once every five years.

Short Circuit Leaves Curiosity with One Arm

NASA has announced that the Mars Curiosity Rover now just has one arm, due to a short circuit that happened while the rover was attempting to retrieve a sample.

Google Reverses Android Lollipop Security Decision

New phones and tablets featuring the latest version of Google's Mobile Operating System, Android 5 "Lollipop," will not have device encryption enabled by default despite earlier promises made by Internet giant.

New Treatment for Migraines Could Bring Much Needed Relief

A new, relatively simple treatment has been developed to ease the pain experienced by those who suffer from migraines. The procedure delivers anesthetic lidocaine directly to the nerves in the back of the nasal cavity, and preliminary research indicates it could offer significant pain relief to migraine sufferers.

Genes Show Where Penguins Called Home During the Ice Age

Surviving an Ice Age may sound like an easy task for a penguin. However, a new study of how climate change has affected emperor penguins over the last 30,000 years found that only three different populations of penguins survived during the last ice age, and the Ross Sea in Antarctica was likely the refuge for one of the populations.

‘Skeletorus’ and ‘Sparklemuffin’ Species Discovered—Seriously Colorful Spiders

Add two more to the list. Not the species list, silly; the list of creatures to avoid when I’m visiting down-under. As it is, Australia has some pretty interesting, and sometimes terrifying, species unique to that region of the world. But with a new study recently published in the journal Peckhamia, researchers are adding two new arachnid species to the list. And they’re quite the colorful bunch.

The Light Theory—How Researchers Are Proving Einstein Right With a Snapshot

As one of these few disciplines, quantum physics falls into a realm of science where well-documented and highly regarded theories take precedence. But explaining these theories requires a deep understanding of the underlying science, and devising lab experiments to illustrate them is a near impossible feat. One research team of American and Swiss physicists with the EPFL Labs in Switzerland, however, are doing just that. And equipped with some wire, a laser and quick-capturing electron microscope they’re proving what Einstein theorized was true — light can act as a particle and a wave.

Methane Based Life Could Exist on Saturn’s Moon, Titan

In a new study published this week by researchers from Cornell University, the team of researchers has modeled a new methane-based life form that can metabolize and reproduce, similar to the oxygen-based life forms here on Earth. And more than that, the researchers say that these life forms could flourish in the harsh, cold environment of Saturn's moon, Titan. Titan's surface is filled with seas of liquid methane that researchers believe could harbor these methane-based cells.
