A man that fancies women with blond hair may announce such almost anywhere. Established scientists frequently work thinly veiled references to the proverbial sexiness of blondes into their talks, to loosen them up, to render the seminar or lecture personal and memorable. On the other hand, I have never seen anybody but Quentin Tarantino put their foot fetish into their work; certainly I do not know of any politician or scientist “putting their or others’ feet in their mouth” this way.

How do astronomers weigh stars?    In most cases stars that are trillions of miles away can't be measured, though astronomers can get a best estimate using numerical models.

But in some instances a star could be measured using inference.    If the star has a transit planet, and that planet has a moon, and both of them cross in front of their star, the size and orbit can be measured to learn about the star.  Has it been done yet?   Well, no, since we have not found a star with both a planet and moon that transit but NASA's Kepler spacecraft should discover several such systems.
Two women who took part in the world's first controlled study of a genetic screening test before IVF have given birth to healthy babies.

The babies are the first deliveries in a pilot study of comparative genomic hybridization (CGH) by microarray, a new method of screening oocytes, female gametocytes involved in reproduction, before in vitro fertilization (IVF) for a full range of chromosomal disorders. 
Amelia Carolina Sparavigna in the department of physics of  Politecnico di Torino says she has discovered geoglyphs, essentially earthwork graphic designs carved into the landscape, near Lake Titicaca is in the Andes Mountains on the border of Peru and Bolivia.

And she did it using Google.

You may not be able to see it so clearly but time and wear would certainly have made geoglyphs less obvious, though how and why anyone would have made them is also not obvious - unless they were insuring some deity or another could see something more interesting than farmers when they looked down.
