Depression may have more far-reaching consequences than previously believed. Recent data suggests that individuals who suffer from a mood disorder could be twice as likely to have a heart attack compared to individuals who are not depressed. This process has been poorly understood — until now. A new study led by Concordia University has found that depressed individuals have a slower recovery

A new study published today in the international journal Addiction demonstrates that even small changes in pub and bar closing hours seem to affect the number of violent incidents. The findings suggest that a one-hour extension of bar closing hours led to an increase of an average of 20 violent cases at night on weekends per 100,000 people per year. This represents an increase in violence of

A University of Cambridge study, which set out to investigate DNA methylation in the human heart and the 'missing link' between our lifestyle and our health, has now mapped the link in detail across the entire human genome. The new data collected greatly benefits a field that is still in its scientific infancy and is a significant leap ahead of where the researchers were, even 18 months ago.

Guppies in the wild have evolved over at least half-a-million years — long enough for the males' coloration to have changed dramatically. Yet a characteristic orange patch on male guppies has remained remarkably stable, though it could have become redder or more yellow. Why has it stayed the same hue of orange over such a long period of time? Because that's the color female guppies prefer. "

Earth's landmasses were not always what they are today. Continents formed as Earth's crustal plates shifted and collided over long periods of time. This video shows how today's continents are thought to have evolved over the last 600 million years, and where they'll end up in the next 100 million years.

Like all galaxies, our Milky Way is home to a strange substance called dark matter. Dark matter is invisible, betraying its presence only through its gravitational pull. Without dark matter holding them together, our galaxy's speedy stars would fly off in all directions. The nature of dark matter is a mystery -- a mystery that a new study has only deepened. "After completing this study, we

An amorphous diamond – one that lacks the crystalline structure of diamond, but is every bit as hard – has been created by a Stanford-led team of researchers. But what good is an amorphous diamond? "Sometimes amorphous forms of a material can have advantages over crystalline forms," said Yu Lin, a Stanford graduate student involved in the research. The biggest drawback with using diamond

New evidence supports idea that taller candidates have evolutionary advantage New research into evolutionary psychology suggests that physical stature affects our preferences in political leadership. The paper, published in Social Science Quarterly, reveals that a preference for physically formidable leaders, or caveman politics, may have evolved to ensure survival in ancient human history.

New research has shown for the first time that omega-3 in fish oil could "substantially and significantly" reduce the signs and symptoms of osteoarthritis. According to the University of Bristol study, funded by Arthritis Research UK and published in the journal Osteoarthritis and Cartilage, omega-3-rich diets fed to guinea pigs, which naturally develop osteoarthritis, reduced disease by

University of Granada researchers have proven that overweight women -- especially those with morbid obesity -- develop this disease at an earlier age Obese women develop breast cancer at a younger age than other women. Furthermore, the likelihood of developing breast cancer is much higher in patients with morbid obesity. This is one of the main conclusions drawn in an article recently

It is known that the unmarried are in general more likely to die than their married counterparts and there is some indication that the divide is in fact getting worse. New research published in BioMed Central's open access journalBMC Public Health looks at the changes in cancer survival over the past 40 years and show that the difference in mortality between the married and never married,

Coral reefs are among the most diverse ecosystems on the planet, second only to tropical rain forests. Bird's nest coral (Seriatopora hystrix) is common throughout the Indo-Pacific and is able to live across a range of depths. However, there is little gene flow between the coral populations at each depth and even the algal endosymbionts (Symbiodinium), which provide energy for the corals to

Scientists develop new nanomaterial that ‘steers’ current in multiple dimensions Scientists at Northwestern University have developed a new nanomaterial that can "steer" electrical currents. The development could lead to a computer that can simply reconfigure its internal wiring and become an entirely different device, based on changing needs.

Auditory working memory and attention, for example the ability to hear and then remember instructions while completing a task, are a necessary part of musical ability. But musical ability is also related to verbal memory and literacy in childhood. New research published in BioMed Central's open access journal Behavioral and Brain Functions shows how auditory working memory and musical aptitude

While it's been long established that watching violent scenes increases aggression levels, a new study in the medical journal Pediatrics suggests that profanity in the media may have a similar effect.

"We read to know we are not alone," wrote C.S. Lewis. But how do books make us feel we are not alone? "Obviously, you can't hold a book's hand, and a book isn't going to dry your tears when you're sad," says University at Buffalo, SUNY psychologist Shira Gabriel. Yet we feel human connection, without real relationships, through reading. "Something else important must be happening." In an
