Found: Genes for Fins, Paws, and Hands

By -
Scientists found the genetic code mice use for growing paws — in spotted gar, after they thought about what happened to fish 300,000,000 years back.

An amateur fossil hunter found a complete ichthyosaur skeleton in Wales, professional fossil hunters found parts of a critter that isn't quite an ichthyosaur in China, and other paleontologists described a cat-size dinosaur that lived in what's now Montana.

Still other scientists named a Cambrian — thing — after an esteemed colleague. Quite a few Cambrian critters are just like nothing that lives on today's Earth.

The Memorare

By Helen Gonsalves -

This popular prayer, a favorite of many Catholics, dates back to the 15th century and takes its name from the first Latin word of the prayer, "memorare," which means "remember." The Memorare is of unknown authorship, although it has been attributed to St. Augustine (354-430), St. John Chrysostom (c. 347-407) and, with more reason, to St. Bernard of Clairvaux (c. 1090-1153). St. Bernard's sermons on Mary were famous, and it was his Cistercian monks in the monastery of Citeaux in the 12th century who popularized the name "Our Lady" for Mary. The Memorare has also been attributed to the French cleric Claude Bernard (1588-1641), known as the "poor priest" of Paris, whose homilies contain passages that echo its words. No matter who wrote this prayer, it was Father Bernard who did much to popularize it, teaching it in hospitals and prisons, where Mary's intercession was effective in working miracles of grace. The first manuscript of the Mem

The Sorrowful and Immaculate Heart of Mary

This is the image most often associated with the writings of the Belgian mystic Berthe Petit. She promoted devotion to the Sorrowful and Immaculate Heart of Mary. During my preparation for the retreat I am giving at the end of the month in Pantasaph, North Wales, I began reading a book by the late John Haffert (once the lay leader of the Blue Army of Fatima). His theory in the book, which speaks of God's "last effort" to convert the world before the coming chastisement, is that we are now living in the third or fourth "day" of the Fatima week. At this time, according to Haffert, we should be promoting devotion to The Immaculate Heart of Mary. I also consulted another book by Dr. Courtnay Bartholomew (whom I have been privileged to meet) which also speaks of the importance of this devotion, linking it with the writings and visions of the mystic Berthe Petit, and the importance of the full title of the Sorrowful and Immaculate Heart. These things will feature in

Why Modesty Is Not Subjective

Hi there, ya'll!  The modest fashion world is one very diverse place.  Even among Catholics, the definition of "modest apparel" can vary greatly from person to person.  Recently I joined a Facebook group that advertised itself as a haven for Catholic women of all ages to share ideas for modest style and makeup and was hoping to learn more about modesty from my fellow Catholic sisters.  After a few days of being a member, though, I sadly left the group feeling a bit discouraged.  No two members seemed to agree on ANY aspect of modesty whatsoever, and the prevailing theme of the whole group was that modesty is subjective, it means something different for each woman and each woman gets to decide what she considers is "modest".  One woman very emphatically declared that she wears bikinis every summer to the beach and doesn't feel that this violates the virtue of modesty in the least.  The same woman also announced that she was never going to caution her d
