July 18, 2014

by Erin Campbell in HighMag Blog

Poor polar bodies typically go the way of that old container of Chinese take-out in your fridge and are eventually dumped. Thanks to a very clever study published in Cell, polar body transfer can prevent the transmission of inherited mitochondrial diseases. Waste not, want not. The meiotic divisions of an oocyte result in the production of an egg in the extrusion of two very small polar bodies. These polar bodies have the same genetic material as the egg but have only a small number of orga........ Read more »

Baboons Trade Morning Favors for All-Day Payoffs

by Elizabeth Preston in Inkfish

Primates basically invented “You scratch my back and I’ll scratch yours.” Baboons, for example, trade grooming for favors from other troop members. Social relationships are important to the monkeys. But it seems they put more effort into certain relationships depending on the time of day: in the morning, lower-ranking baboons invest more energy in grooming […]The post Baboons Trade Morning Favors for All-Day Payoffs appeared first on Inkfish....

What makes a cancer a cancer? The Hallmarks of Cancer

by Robb Hollis in Antisense Science

Cancer – the ‘C word’ in far too many of our lives. Wherever you are, it’s unlikely you’ll be able to avoid the news reports and personal stories about people fighting against cancer. Understanding how the disease occurs and how it takes hold over the body is key for developing effective new treatments and managing patients in the clinic, and so huge amounts of money are invested in cancer research every year. But what actually is cancer and how does it develop?... Read more »

Men's sex appeal boosted by taking risks like a cave man

by Christian Jarrett in BPS Research Digest

A willingness to take risks enhances men's sex appeal. This much we know from past research. What's not clear, is whether this is because of cultural beliefs about traditional gender roles, or if it's an evolutionary hang-over (or perhaps both). John Petraitis and his colleagues have put these two explanations to the test by drawing a distinction between risk-taking behaviours that reflect the challenges faced by our ancestors, and contemporary risks based around modern technology.Over two-hundr........

Ultrafine particulate matter air pollution, mice and autism

by Paul Whiteley in Questioning Answers

Reading the headline "Study links air pollution to autism, schizophrenia" in a media piece about the study by Joshua Allen and colleagues* (open-access here) made me want to delve a little more into this research. I've talked before about air pollution and autism (see here) on this blog. Although a healthy degree of scepticism is to be expected with any autism correlation, particularly when it comes to something as generalised as air pollution (or pesticide exposure) there is a growing rese........

Cross-cultural variation in men’s preference for sexual dimorphism in women’s faces

by Farid Pazhoohi in Epistemophil

Both attractiveness judgements and mate preferences vary considerably cross-culturally. We investigated whether men’s preference for femininity in women’s faces varies between 28 countries with diverse health conditions by analysing responses of 1972 heterosexual participants. Although men in all countries preferred feminized over masculinized female faces, we found substantial differences between countries in the magnitude of […]... Read more »
