Depression predicts single relationship status in later adulthood, study finds

No Result View All Result No Result View All Result Among the most frustrating and keenly felt consequences for individuals who suffer from depression and anxiety are those that affect present and future relationships. At times when individuals need the most support, the interpersonal repercussions of mental health issues can severely negatively impact relationships and even lead to their end.A recent study on depression and anxiety in early adulthood, published in , examines just this aspect of these prevalent and widespread mental health problems. The study takes advantage of longitudinal...

Genetic predisposition to schizophrenia may increase risk of psychosis from cannabis use

Genetic predisposition to schizophrenia may increase risk of psychosis from cannabis use

It has been long been known that cannabis users develop psychosis more often than non-users, but what is still not fully clear is whether cannabis actually causes psychosis and, if so, who is most at risk. A new study published in by researchers at the Centre for Addiction and Mental Health (CAMH) and King's College London helps shed light on both questions. The research shows that while cannabis users had higher rates of psychotic experiences than non-users across the board, the difference was especially pronounced among those with high genetic predisposition to schizophrenia."These...

The Role of Vision in the Emergence of Mate Preferences

The Role of Vision in the Emergence of Mate Preferences

AdvertisementThe Role of Vision in the Emergence of Mate PreferencesCross-cultural research has repeatedly demonstrated sex differences in the importance of partner characteristics when choosing a mate. Men typically report higher preferences for younger, more physically attractive women, while women typically place more importance on a partner’s status and wealth. As the assessment of such partner characteristics often relies on visual cues, this raises the question whether visual experience is necessary for sex-specific mate preferences to develop. To shed more light onto the emergence of...

Scientists make pivotal discovery on mechanism of Epstein-Barr virus latent infection

Scientists make pivotal discovery on mechanism of Epstein-Barr virus latent infection

January 21, 2021byResearchers at The Wistar Institute have discovered a new enzymatic function of the Epstein-Barr Virus (EBV) protein EBNA1, a critical factor in EBV's ability to transform human cells and cause cancer. Published in Cell, this study provides new indications for inhibiting EBNA1 function, opening up fresh avenues for development of therapies to treat EBV-associated cancers.EBV establishes life-long, latent infection in B lymphocytes, which can contribute to development of different cancer types, including Burkitt's lymphoma, (NPC) and Hodgkin's lymphoma.The Epstein-Barr...

An architecture firm has designed a floating 5-star hotel that would generate its own electricity by rotating, but it may be too futuristic for its own good

The design by Hayri Atak Architectural Design Studio is for a five-star hotel with 152 rooms that would span more than 376,000 square feet, or about 8.6 acres. Construction on the hotel has not begun, and feasibility studies and technical assessments are ongoing, Kübra Türk, one of the architects working on the project, told Insider. The hotel would rotate to generate electrical energy, according to the architects. An artistic rendering of the floating hotel.

This pterosaur supported its giant neck with bones built like bicycle wheels

This pterosaur supported its giant neck with bones built like bicycle wheels

About 100 million years ago, gigantic flying reptiles with necks longer than those of giraffes cruised the skies of modern-day Morocco. Scientists think this kind of pterosaur, with its large jaw and slim neck, preyed on fish, small mammals, and even baby dinosaurs. But how their necks didn’t snap as they carried their prey has long been a mystery. Now, a new study shows the bones inside had an intricate spokelike structure that made them strong and stable, but light enough for flight.Azhdarchid pterosaurs (named after a dragonlike creature in Persian mythology) from Morocco are some of the...

The system, which works by transferring heat from a nuclear reactor to a liquid propellant to generate thrust, provides twice the propellant efficiency of chemical rockets. To speed up the pace of NTP tech development, the Pentagon's Defense Advanced Research Projects Agency (DARPA) has a trio of companies to build and demonstrate a nuclear-based propulsion system on a spacecraft above...
