Women and fragrances: Scents and sensitivity

by Dr. Jekyll in Lunatic Laboratories

Researchers have sniffed out an unspoken rule among women when it comes to fragrances: Women don’t buy perfume for other women, and they certainly don’t share them. Like boyfriends, current fragrance choices are hands off, forbidden–neither touch, nor smell. You can look, but that’s all, says BYU industrial design professor and study coauthor Bryan Howell....

How to Succeed at Clinical Genome Sequencing

by Daniel Koboldt in Massgenomics

Whole-genome sequencing holds enormous potential to improve the diagnosis and treatment of human diseases. Although this approach is the only way to capture the complete spectrum of genetic variation, its application in clinical settings has been slow compared to more targeted strategies (i.e. panel and exome sequencing). Everyone talks about cost as the main contributing factor for […]...

Psychologists asked these skin cancer patients to draw their melanomas

by BPS Research Digest in BPS Research Digest

Early diagnosis of cancer can save lives, yet so many people wait before reporting important symptoms. This is an issue where psychology can make a major contribution by helping to explain why some patients delay reporting their symptoms to a clinician. A pilot study published recently in Psychology and Health uses an unusual approach for this purpose, specifically in the context of skin cancer, by asking patients to draw their melanomas.Suzanne Scott at Kings College, London and her collea........

Oxytocin moving on: ADHD and inattentiveness

by Paul Whiteley in Questioning Answers

Dare I mention the term 'cuddle hormone' when it comes to oxytocin?Well, according to a recent news piece in Nature (see here), the 'cuddle hormone' days of oxytocin might well be numbered as science is starting to come to grips with just how complicated a role this hormone might have when it comes to biology and behaviour. Of course we've seen hints of this for quite a while now as autism research in particular comes to grips with the idea that oxytocin may not be the magic 'sociability' b........ Read more »

Element breath!

by Rosin Cerate in Rosin Cerate

Exposure to relatively toxic metals and metalloids can result in a wide range of symptoms, some of which are pretty weird. Body parts can change colour, skin can erupt with lesions, bones can soften, hair can be shed, the nervous system can go haywire, and the smell of one's breath can transition from unnoticeable to downright peculiar.Long-term exposure to lead (e.g. working at a lead mine or smelter) can cause your breath to acquire a strange sweetish metallic smell, particularly in the mornin........

What’s that!? Brain network that controls, redirects attention identified

by Dr. Jekyll in Lunatic Laboratories

Researchers at Columbia University Medical Center (CUMC) have found that key parts of the human brain network that give us the power to control and redirect our attention–a core cognitive ability–may be unique to humans. The research suggests that the network may have evolved in response to increasingly complex social cues.... Read more »

Vaginal douches may expose women to harmful phthalate chemicals

by Dr. Jekyll in Lunatic Laboratories

Women who use feminine care products called douches may increase their exposure to harmful chemicals called phthalates–and black women may be at particularly high risk due to frequent use. Public health officials advise against the use of douching products, which can hide vaginal infections and lead to other serious health problems. Despite that, douching products are still a popular item on the drug store shelf, and are disproportionately used by black women.... Read more »

Fitness Boosts White Matter Integrity in Aging

What's a Colorblind Person's Favorite Color? Yellow

by Elizabeth Preston in Inkfish



As much as you think your tastes are unique, psychologists say they can guess your favorite color. It's likely to be blue. And it's especially unlikely to be yellow—unless you're colorblind. Men with red-green colorblindness have preferences that are essentially opposite from everyone else's. The finding could help scientists understand why humans like what they like, and how colorblind people see the world differently.

Some researchers have claimed that the human love of blue is universa........ Read more »

Ovaries March To A Different Drummer

by Mark Lasbury in As Many Exceptions As Rules

A woman’s right ovary kicks her left ovary’s behind. It puts out more hormones and more pregnancies result from right-sided ovulations than from left-sided ovulations. And there’s none of this right-left stuff you’ve been taught, the ovaries don’t have to take turns ovulating every other month. In fact, a study showed that the best chance for pregnancy is if the ovulation pattern is left-left-right over a three-cycle interval. ... Read more »

Older people frequently underestimate their own memory skills

by BPS Research Digest in BPS Research Digest

By guest blogger David RobsonAristotle once compared the human mind to a wax tablet. When we are young, the wax is warm and soft; it is easy to make an impression and record our thoughts and feelings. With age, the wax hardens – the older impressions fade, and it is harder to carve out new images in their place.This view of memory, at least among the general public, has changed little in the 2300 years since. Many of us still believe that the brain’s “plasticity” – its ability to adapt........ Read more »
