Contrary to popular perception, today's teenagers are actually growing up more slowly than their predecessors, with 18-year-olds now behaving like 15-year-olds of yesteryears, suggests new research.
The findings published in the journal Child Development suggest that today's teenagers are taking longer to engage in adult activities such as drinking alcohol, working, driving, or having sex.
"The developmental trajectory of adolescence has slowed, with teenagers growing up more slowly than they used to," explained Jean Twenge...

Super-massive black holes found in the centers of galaxies can form gravitationally bound pairs when galaxies merge, confirms a study led by Indian scientists.
The study published in the journal Nature Astronomy sheds light on a class of black holes having a mass upwards of one million times the mass of the Sun.
The study was led by Preeti Kharb from the National Centre for Radio Astrophysics (NCRA) of the Tata Institute of Fundamental Research (TIFR) in Pune and co-authored by Dharam Vir Lal, also at NCRA-TIFR and David...

Scientists have developed a new type of water-proof solar cell which can provide electricity even after being soaked in water or stretched and compressed.
The finding could open the way for wearable solar cells, which will provide power to devices such as health monitors incorporated into clothing, researchers said.
These could include sensors that record heartbeats and body temperature, for example, providing early warning of medical problems, they said.
Researchers, including those from the University of Tokyo...

People who suffer from schizophrenia have three times higher risk of death and are more likely to die younger, a study has found.
The study looked at all deaths in Ontario in Canada over a 20-year period (1993-2012) - more than 1.6 million deaths - to understand trends in schizophrenia.
Of these, 31,349 were deaths of people with schizophrenia and more were female, younger and living in lower-income neighborhoods compared with the general population.
Despite increases in life expectancy, people with schizophrenia died eight years...

Kolkata, September 18
A team of experts from India and Sweden has flagged concerns over uncontrolled dumping of partly treated/untreated urban waste into rivers— leading to the spread of antibiotic resistance.
Drawing attention to pollution of water courses from domestic waste, they found that antibiotic resistance genes were significantly more abundant in river sediments collected from the city than from upstream sites.
"The growing resistance amongst bacterial pathogens limits our ability to treat infections. Environment plays an important role in...
Listening to music can cause women to perceive a man's face as more attractive, and make her more willing to date him, a study claims.
Researchers from the University of Vienna in Austria investigated the impact of musical exposure on the how one evaluates the faces of poeple of opposite sex.
"Facial attractiveness is one of the most important physical characteristics that can influence the choice of a partner," said Helmut Leder, from the University of Vienna.
"We wanted to find out how music can alter the perception of this feature," said Leder....

Scientists have characterised wind and cloud patterns of the night side of planet Venus for the first time, and found that it behaves very differently from the part facing the Sun.
The night side exhibits unexpected and previously-unseen cloud types, morphologies, and dynamics — some of which appear to be connected to features on the planet's surface.
"This is the first time we've been able to characterise how the atmosphere circulates on the night side of Venus on a...

Third-hand smoke (THS) results that when exhaled smoke and smoke emanating from the tip of burning cigarettes gets on surfaces such as clothing, hair, homes, and cars may adversely affect health and the effects worsen with time.
The findings, published in the journal Clinical Science, suggest that third-hand smoke toxins could be damaging to liver and brain tissues.
Using a system in which the exposure of mice to third-hand smoke mimics that of human exposure in the homes of smokers, the researchers investigated the effects...

Worried about losing your hair? Take a breath from a study that claims that bald men are perceived as more attractive, confident, and dominant.
"Choosing to dispense with one's hair is arguably a form of nonverbal behaviour, a form of expression which communicates information about the self otherwise difficult to observe," researchers from The University of Pennsylvania.
The team gave three major tests to college students, both men and women, asking them to rate images of men according to attractiveness, confidence and...
Children who own cell phones are more likely to fall prey to cyberbullying, a study warns.
Researchers collected survey data on 4,584 students in grades 3, 4 and 5 between 2014 and 2016.
They found that overall, 9.5 per cent of children reported being a victim of cyberbullying.
Children who owned cell phones were significantly more likely to report being a victim of cyberbullying, especially in grades 3 and 4, researchers said.
