  • Happy belated birthday, Mary Anning!

    igh tides in winter which revealed the fossil deposits, just as it was the same tides which made the rock face unstable and liable to collapse. Hers was not to be a long and happy life. She died of breast cancer at the age of 47 on 9th March 1847. In her lifetime success and recognition evaded her. She had been barred from admission to the Geological Society on account of her gender (women were not admitted to their ranks until 1904). At one stag…

  • Biology Explainer: The big 4 building blocks of life–carbohydrates, fats, proteins, and nucleic acids

    …ll selection of different materials: bricks, mortar, iron, glass, and wood. Arranged in different ways, these few materials can yield a huge variety of structures. We encountered functional groups and the SPHONC in Chapter 3. These components form the four categories of molecules of life. These Big Four biological molecules are carbohydrates, lipids, proteins, and nucleic acids. They can have many roles, from giving an organism structure to be…

  • After Newtown missteps, journalists get guidelines

    …almost twice as likely to say that they don’t want to live or work near a person with mental illness if they read an article about a person with mental illness involved in a mass shooting, according to a study published March 20 in the American Journal of Psychiatry. Interestingly, this tendency is the same even if the article avoids any mention of mental illness. This may be because this link between violence and mental illness is deeply engrain…

  • Unicorns and Brainbows

    orite, shown below: A cerebellar flocculus, a lobe in the cerebellum, from the original Brainbow paper (Source) Since its original description, researchers have used the Brainbow concept extensively — it has been cited 361 times, according to the Web of Science – and extended it into zebrafish and fruit flies, both species that researchers frequently use in experiments to trace gene expression and how animals develop. But though Lich…

  • Is the bar high enough for screening breast ultrasounds for breast cancer?

    …ve dense breasts and lobbying to roll out all sorts of imaging studies quickly, no matter how well they have been studied, it would not be worth posting. Dense breasts are worrisome to women, especially young women (in their 40s particularly) because they have proved a risk factor for developing breast cancer. Doing ultrasound on every woman with dense breasts, though, who has no symptoms, and a normal mammogram potentially encompasses as many a…

  • Depressing genes

Only rarely do gene variants cause primarily negative consequences, such as BRCA1, the breast cancer gene, or APOE epsilon 4, the early-onset Alzheimer’s disease gene. If insurance companies did, in fact, try to weed out clients based on their genetic make-up, they would soon find that most gene variants that put carriers at risk for some diseas…

That’s right, fewer babies are born on the 4th (and 5th) of July than on other days that month. That’s a hint that the data come from US births. You might know that the 4th is a big holiday in the United States.But how does a fetus know it’s a holiday? What we’…

Her graduate and postdoctoral work determining infections caused by bacterial contamination and creating a new method of distillation improved the safety of intravenous feeding. She then spent 35 years working on tuberculosis, along the way inventing the first reliable test to diagnose the disease. Dr. Seibert broke the stereotype of ìscientistî by being one of two women in her field of tuberculosis research prese…
