What are blue balls? Many people – health care providers included – are familiar with this term in reference to the discomfort that occurs in response to prolonged sexual arousal without orgasm.Although no one knows how the pain of the blue balls begins, most of them cause the blood to flow slowly from the testicles due to the lack of orgasm during sex.One of the most important physiological aspects of sex is the flow of blood to various parts of the body, including the genitals. The genital symptoms of sexual arousal include the discharge of the reproductive organs leading to…
Background noise – like chatter in a coffee shop or the drone of passing cars – can slow down our reading speed, but according to a study of Russian readers, it doesn’t affect how well our brains understand text.The study looked at the effects of auditory noise and visual distractions such as typos or poor handling. Surprisingly, researchers at the National Research University Higher School of Economics in Russia found that they are struggling with the confusion of the word increasing rapidly reading, perhaps because we find the process very annoying and we want to finish reading as soon as…
A team of archaeologists has discovered that our obsession with hair removal dates back to Roman times.Archaeologists are working at Wroxeter Roman City, in Shropshire, England. they will find A large collection of over 50 tweezers at the site dating from the 2nd to 4th century CE.They also found skin lotion, perfume bottles, jewelry, and makeup—showing how important cleanliness and beauty were to the Romans.English Heritage says hair removal practices were as common for men as they were for women, noting that men involved in sports such as wrestling were expected to remove their hair.Cameron Moffett, English Heritage Curator at…
Like metaphorically walking a mile in someone else’s shoes, looking into the eyes is ‘seeing’ with someone else’s eyes: We follow someone else’s eyes to find out what attracted them, or we can try and find out what the other person sees. view is blocked.New research by biologists from Lund University in Sweden challenges the idea that mammals were the first to develop cognitive abilities.The researchers’ observations of alligators and birds suggest that visual observation, which humans have been studying for two years, may have evolved from dinosaurs 60 million years ago.Only a few species, especially monkeys, apes, wolves and…
This jump means that space is shrinking, which reduces the drag on satellites and other low-altitude objects – by about a third by 2070, calculates Ingrid Cnossen, a researcher at the British Antarctic Survey.On the face of it, this is good news for satellite users. Their payloads must be active for a long time before they fall to Earth. But the problem is with other things that share this distance. The accumulation of space debris – various types of debris left in orbit – continues for a long time, increasing the risk of collisions with currently operating satellites.More than 5,000…
Scientists have reprogrammed cells in the human stomach into cells that release insulin in response to high blood sugar levels in a breakthrough that promises a better way to fight diseases like type 1 diabetes.The experiment, led by researchers at Weill Cornell Medicine in the US, revealed that insulin-secreting gastrointestinal cells (GINS) reversed diabetes in mice.Pancreatic beta cells are normally responsible for secreting the hormone insulin in response to high blood sugar levels. In people with diabetes, these cells become damaged or die, which interferes with their ability to move glucose into cells to make fat.Although GINS cells are not…
Fruit flies can be very annoying when they hover around your living room or land in your wine. But we have a lot to thank for this little problem – it changed the science of medicine and medicine.Both flies and mosquitoes belong to the Diptera, a group of insects with only two wings (from the Greek di meaning two, and pteron meaning wing). However, just as many people accept the negatives and positives of their peers, we should not judge flies by their negative behavior alone.We need to open our eyes to see their great economic and ecological importance, as…
Among the approximately 370,000 known species of plants that grow in the world, the taste of blood is rare. But it is only one plant that is known to eat a little.Triphyophyllum peltatum is a rare plant from the tropical forests of Sierra Leone in West Africa that is known to trap insects from time to time. Until recently, researchers have struggled to successfully cultivate the plant to determine what causes its sudden hunger for insect prey.Now researchers from the Leibniz University Hannover and the University of Wurzburg in Germany have discovered more about the life of a very special…
Many people think that postpartum depression is a problem that only affects women. But the truth is, postnatal depression affects almost as many men as women – with one study estimating that it affects 10 per cent of men.Despite how common postpartum depression is in men, not much is known about it. This can make it difficult to know if you may have postnatal depression – and how to get help if you do.Here’s what you need to know.Why does it happen?There are many causes of postpartum depression. And, contrary to popular belief, it’s not because of hormones. Even in…
The search for mysterious streaks hanging in the sky around the heart of the Milky Way has found new people, connecting the edge of the galactic plane and pointing to the intergalactic space.The magnetic strings are the remnants of the Sagittarius A* black hole that interacted with the surrounding atmosphere millions of years ago, says astronomer Farhad Yusef-Zadeh of Northwestern University.Although Sgr A* is quiet now, these remnants suggest that the center of our galaxy has been active in the recent past – in astronomical times, that is. And their discovery also means that the center of our galaxy, which…
