It is nice to get people to do stuff you like. And luckily, just by hanging out with the people around you, you probably already found a lot of ways to accomplish this.... Read more »

The majority of cellular proteins are rapidly degraded and replaced with newly synthesized copies, minimizing accumulation of potentially toxic damage and ensuring a functional proteome throughout a cell’s lifetime. Several studies have measured global protein turnover rates in yeast and mammals and reported an average protein half-life of 1.5 hr to 1–2 days, respectively.... Read more »

Father’s involvement in raising a child, on average, brings good news. It leads to lower child mortality and better social, psychological and educational outcomes. So why do some men choose not to invest in their children? According to a new study, at least part of the reason may be related to testicle size and testosterone levels.... Read more »

For most of human history, dreaming has been seen as a second “reality” in which altered forms of perception provide insights into ourselves and others, our fears, fantasies and motivations or even the future.
What Freud referred to as the “royal road to the unconscious” served as a source of wonderment and prophecy. So what do we think about it now?
What is dreaming? What does science say? And what mysteries remain?... Read more »
Forget elaborate dances, sweet serenades or complicated foreplay. And throw away the Spanish fly and oysters. If you’re a female silkmoth, chances are that your would-be mate is already drunk on your very own elixir of love if he’s within whiffing distance. It takes just 170 molecules of the sex pheromone bombykol to put a male silkmoth in the mood.
Farmers have been using bombykol for years to bamboozle love-sick moths in their fields. But how so few molecules elicit such a strong behavioural response has been somewhat of a mystery to scientists. But in a new study, a team of Japanese researchers have cleverly deciphered the neural circuitry of the Bombyx mori olfactory system as it responds to the sex pheromone.... Read more »

New research shows that metabolically healthy women have the same cardiovascular disease risk regardless of their BMI, according to research presented at the ESC Congress by Dr Søren Skøtt Andersen and Dr Michelle Schmiegelow from Denmark. The findings in more than 260,000 subjects suggest that obese women have a window of opportunity to lose weight and avoid developing a metabolic disorder, which would increase their CVD risk....

Almost all animals have an internal body clock, keeping several functions, including sleeping and eating, synchronised with the light/dark cycle around a 24-hour day. Humans are no exception. If we have to travel across the globe to a new time zone, our body clock takes about a day to adjust to the new time for every hour the clock moves.
This may result in several days of feeling tired and ‘out-of-tune’, known as jet-lag. Not surprisingly, it’s considered a nuisance, but how much do we really understand about this phenomenon?... Read more »

Most cultures include alcoholic beverages as part of their usual diet. Alcohol intake is different over world regions regarding the habitual type of beverage and the frequency and average intake. In general terms, the consumption of alcoholic beverages is increasing worldwide. Unipolar depression is the most prevalent mental disorder in the world and it is increasing steadily.... Read more »

It may have been more than 2000 years ago, but Hippocrates was not far from the truth when he wrote “all disease begins in the gut”. Gut health is critical to overall health. Colonies of benevolent bacteria reside in your entire digestive tract, predominantly the large intestine. In fact, you are made up of more microbes than human cells. This live-in colony of microbes is your digestion powerhouse, breaking down food into its building blocks so it can absorb the nutrients.... Read more »

Diet drinks are no help in the fight against obesity and may actually encourage over-eating, according to a US academic who recently argued this point in the journal Trends in Endocrinology and Metabolism.
Susan Swithers reviewed studies that suggest normal or mildly overweight people who consumed artificially-sweetened drinks were more likely to gain weight when compared to those who did not.
The studies showed that, in two separate groups of adolescents, drinking artificially-sweetened drinks was associated with increased body mass index and body fat.... Read more »

Edible insects are great alternatives to conventional sources of meat as they’re cheap, plentiful and excellent sources of protein and fat, as well as vitamins and minerals.
In many countries, eating insects doesn’t raise eyebrows. How palatable they appear to a person is largely determined by culture.
Analyses of insects also show huge variation in nutritional value and composition – between species, their stages of development and even due to the insects’ diet.
With around 2000 edible insect species worldwide, the below are some of the better alternatives to eat... Read more »

We all have that Facebook contact (if not, in the old sense of the word, friend) who is subject to oversharing. Incessant updates about relationships, jobs, holidays; very public demonstrations of affection; insistent “liking”: the site is full of serial offenders. But for most, this generally amounts to a minor annoyance or something to laugh about. A recent study, however, has argued that sharing photographs on Facebook can, and does, have a direct impact on our personal relationships offline too.... Read more »

From Siri answering our questions and Watson advising nurses to smart apps that aggregate information to help us out (or spy on us), artificial intelligence is transforming our world. Despite incredible advances, somehow these amazingly “intelligent” systems sometimes seem profoundly stupid. Hector Levesque, a professor of computer science at the University of Toronto, likens them to savants. He was recently awarded the Research Excellence Award at the International Joint Conference on Artificial Intelligence in Beijing; he used his acceptance speech to highlight important questions about our approach to artificial intelligence and what it can tell us about ourselves....

With easy access to energy-rich junk food and modern living with a sedentary lifestyle, more and more people are becoming slaves to excessive fat consumption. Yet being a couch potato is dangerous for our health. Studies on the human genome variation show there are significant differences in the genome of bacteria that live in our intestine. A latest research published in Nature reveals that the bacterial population in the intestine varies significantly from obese to thin bodies. This indicates that people with fewer bacterial species in their intestine are more likely to develop complications, such as cardiovascular diseases and diabetes.... Read more »
