Lake Shore Drive in its present incarnation is a relatively recent addition to Chicago’s landscape. Built in pieces over much of the last century, the road was known variously as Leif Erickson Drive and Field Boulevard before it was christened with its current name in 1946. The germ of the idea, however, began in 1882 ... |

Study: Most Plastics Leach Hormone-Like Chemicals Most plastic products, from sippy cups to food wraps, can release chemicals that act like the sex hormone estrogen, according to a study in Environmental Health Perspectives.

products are now marketed as BPA-free, and manufacturers have begun substituting other chemicals whose effects aren't as well known.

FR. AYODELE AYENI CsSP April 2, 2012 At the dawn of creation, "the Spirit of God was moving over the surface of the waters (Genesis 1.2)." The waters at creation not only manifest the symbolism of water in Christian theology, but also its creational importance. Water sustains life and its absence spells doom or death. ... |
the Ark gives a Christian account of the havoc excessive water may cause, even if there will be a rebuilding or newness that follows. However, wherever water cohabits with the Spirit of God, as we see in Genesis 1.2, creational order unfolds from chaos. The Spirit of God hovering over water gives life and saving effect... |
the river goes, every living creature that swarms will live" (Ezekiel 47.9). Water and Spirit have come a long way. In recognition of the association of water with the Spirit, we now say, in the Second Eucharistic Prayer: "Make holy, therefore, these gifts, we pray, by sending down your Spirit upon them like the dewfal... |
associated with water, in the form of a dewfall, with the mission of creating something new - the transubstantiation (changing) of bread and wine into the Body and Blood of Christ. St. Paul already anticipated this link between water and Spirit when he said: "For in the one Spirit we were all baptized into one body - J... |
slaves or free - and we were all made to drink of one Spirit (1 Corinthians 12.13)." What a theological evolution! St. Paul anticipated the theological link between water and spirit. The instructions of God at creation (Genesis 1.1-2.4) brought creation into being, and every creature was given its limits, including wat... |
for the sea, a perpetual barrier that it cannot pass; though the waves toss, they cannot prevail, though they roar, they cannot pass over it" (Jeremiah 5.22). The human person pushed his boundary by "sin of origin," only to discover his frailty. When humans needed regeneration or salvation from their sins, water was re... |
of your chambers on the waters, you make the clouds your chariot, you ride on the wings of the wind. . . . When you send forth your spirit, they are created; and you renew the face of the earth" (Psalm 104.3, 30). Humans can either lose their identity through sin, or have their identity denied them by servitude, like |
the enslavement of the Israelites in Egypt. The restoration of a lost identity comes via redemption. God redeems by re-creating the primeva l state of creation, not necessarily through destruction, but by manifesting his power as creator. With the Israelites, he chose water as the medium of his re-creation. The waters ... |
from Egypt, a fact which coincided with their new identity as a people. St. Paul theologized on the crossing of the sea in these words: "I do not want you to be unaware, brothers and sisters, that our ancestors were all under the cloud, and all passed through the sea, and all were baptized into Moses in the cloud and |
in the sea" (1 Corinthians 101-3). The birth of a new people, Israel, by the passing through the sea, keeps giving new birth and identity to all who approach the baptismal font, especially on Easter night. The column of light which announces God's presence among the Israelites, symbolized by the paschal candle, and the... |

Every Easter season actualizes God's presence and intervention on behalf of his people, in all circumstances of their lives. The baptismal font symbolizes those water... |
just as the Israelites received their identity before God. Also, since the Israelites received a collective identity as a nation of people, at Baptism, every Christian is incorporated, as an adopted child of God, into the Body of Christ, as a member of the Church. At Easter, we celebrate our individual and collective C... |

Search: Nuclear chemistry, Darmstadtium, Germany In honour of scientist and astronomer Nicolaus Copernicus (1473-1543), the discovering team around Professor Sigurd Hofmann suggested the name copernicium with the element symbol Cp for the new element 112, discovered at the GSI Helmholtzzentrum für Schwerionenforschung ... |
was Copernicus who discovered that the Earth orbits the Sun, thus paving the way for our modern view of the world. Thirteen years ago, element 112 was discovered by an international team of scientists at the GSI accelerator facility. A few weeks ago, the International Union of Pure and Applied |
Chemistry, IUPAC, officially confirmed their discovery. In around six months, IUPAC will officially endorse the new element's name. This period is set to allow the scientific community to discuss the suggested name copernicium before the IUPAC naming. "After IUPAC officially recognized our discovery, we – that is all s... |
in the discovery – agreed on proposing the name copernicium for the new element 112. We would like to honor an outstanding scientist, who changed our view of the world", says Sigurd Hofmann, head of the discovering team. Copernicus was born 1473 in Torun; he died 1543 in Frombork, Poland. |
Working in the field of astronomy, he realized that the planets circle the Sun. His discovery refuted the then accepted belief that the Earth was the center of the universe. His finding was pivotal for the discovery of the gravitational force, which is responsible for the motion of the planets. |
It also led to the conclusion that the stars are incredibly far away and the universe inconceivably large, as the size and position of the stars does not change even though the Earth is moving. Furthermore, the new world view inspired by Copernicus had an impact on the human self-concept |
in theology and philosophy: humankind could no longer be seen as the center of the world. With its planets revolving around the Sun on different orbits, the solar system is also a model for other physical systems. The structure of an atom is like a microcosm: its electrons orbit the |
atomic nucleus like the planets orbit the Sun. Exactly 112 electrons circle the atomic nucleus in an atom of the new element "copernicium". Element 112 is the heaviest element in the periodic table, 277 times heavier than hydrogen. It is produced by a nuclear fusion, when bombarding zinc ions onto |
a lead target. As the element already decays after a split second, its existence can only be proved with the help of extremely fast and sensitive analysis methods. Twenty-one scientists from Germany, Finland, Russia and Slovakia have been involved in the experiments that led to the discovery of element 112. |
Since 1981, GSI accelerator experiments have yielded the discovery of six chemical elements, which carry the atomic numbers 107 to 112. The discovering teams at GSI already named five of them: element 107 is called bohrium, element 108 hassium, element 109 meitnerium, element 110 darmstadtium, and element 111 is named |
roentgenium. The new element 112 discovered by GSI has been officially recognized and will be named by the Darmstadt group in due course. Their suggestion should be made public over this summer. The element 112, discovered at the GSI Helmholtzzentrum für Schwerionenforschung (Centre for Heavy Ion Research) in Darmstadt... |
been officially recognized as a new element by the International Union of Pure and Applied Chemistry (IUPAC). IUPAC confirmed the recognition of element 112 in an official letter to the head of the discovering team, Professor Sigurd Hofmann. The letter furthermore asks the discoverers to propose a name for the |
new element. Their suggestion will be submitted within the next weeks. In about 6 months, after the proposed name has been thoroughly assessed by IUPAC, the element will receive its official name. The new element is approximately 277 times heavier than hydrogen, making it the heaviest element in the periodic |
table. “We are delighted that now the sixth element – and thus all of the elements discovered at GSI during the past 30 years – has been officially recognized. During the next few weeks, the scientists of the discovering team will deliberate on a name for the new element”, says |
Sigurd Hofmann. 21 scientists from Germany, Finland, Russia and Slovakia were involved in the experiments around the discovery of the new element 112. Since 1981, GSI accelerator experiments have yielded the discovery of six chemical elements, which carry the atomic numbers 107 to 112. GSI has already named their offic... |

Luteinizing hormone (LH) is produced by the pituitary gland. In women, LH helps regulate the menstrual cycle and egg production (ovulation); in men, LH stimulates the production of testosterone, which plays a role in sperm production. Women's LH levels normally |

You might recognize prominent primatologist Frans de Waal from lectures he has given about his research on primate behavior, which have been popularized on YouTube. His face is familiar to |
chimpanzees, too; some chimps that he knew as babies still recognize him even after decades apart, he said. "Chimpanzees have the advantage that you cannot ask them questions, so you |
have to watch (their) behavior to see what they do," says de Waal, director of Emory University's Living Links Center, in his Dutch-accented voice that is both gentle and authoritative. |
He adds, with dry humor: "With humans, you can ask questions and you get all sorts of answers I don't trust, so I prefer to work with chimpanzees for that |
reason." Living Links is part of the oldest and largest primate center in the United States: The Yerkes National Primate Research Center, a secluded grassy area in suburban Atlanta where |
humans work in office trailers and other animals play in open-air compounds. De Waal, who has been at the center for more than 20 years, has made a career out |
of finding links between primate and human behavior, particularly in the areas of morality and empathy. You might think of "morality" as special for humans, but there are elements of |
it that are found in the animal kingdom, says de Waal -- namely, fairness and reciprocity. His latest study, published this week in the journal Proceedings of the National Academy |
of Sciences, suggests that chimpanzees may show some of the same sensibility about fairness that humans do. The popular belief that the natural world is based on competition is a |
simplification, de Waal says. The strength of one's immune system, and the ability to find food, are also crucial. And many animals survive by cooperating. "The struggle for life is |
not necessarily literally a struggle," he said. "Humans are a highly cooperative species, and we can see in our close relatives where that comes from." Mammals such as wolves, orcas |
and elephants need their groups to survive, and empathy and cooperation are survival mechanisms. De Waal discusses these mechanisms in his 2009 book "The Age of Empathy: Nature's Lessons for |
