[Scary] Pregnant woman says 'maternal instinct' helped her kill attack
FORT MITCHELL, Ky. - A pregnant woman who killed her attacker said a maternal instinct helped her fight off the woman who investigators believe was after her unborn child."I do believe that I fought harder because it was for my child,"Sarah Brady told ABC's "Good Morning America"in interviews aired Sunday and Monday. "It is a maternal instinct to protect your child to the very end."Katherine Smith, 22, died Thursday after luring Brady to her apartment to pick up a package supposedly delivered to the wrong address. When Smith pulled out a knife and attacked the pregnant woman, Brady fought back, striking Smith on the head with an ash tray and stabbing her three times with her own knife, police said. Brady, 26, said she didn't know Smith before the two met at Smith's apartment and can't be certain why Smith wanted to kill her."I really am not sure what was going through her mind,"Brady told ABC. "The only thing I thought was that she was going to kill me and my child and that is the only thing that ran through my mind." Rice Researchers Gain New Insight Into Nanoscale Optics
New findings in the journal Nano Letters demonstrate an important analogy between electronics and optics that may enable light waves to be coupled efficiently to nanoscale structures and devices. Rice University scientists have discovered a universal relationship between the behavior of light and electrons, and they believe it may be exploited to create nanoscale antennae that convert light into broadband electrical signals capable of carrying approximately 1 million times more data than existing on-chip interconnects. Wi-Fi Kit Keeps Drivers Connected
An in-vehicle wireless network adapter creates a moving Wi-Fi hotspot, but it won't be cheap to stay connected during your commute. So how 'bout the satellite radio networks partner with an ISP for a less-spendy mobile internet system? In Autopia. The Page One Pope: A Legacy of Resources
Questions to consider for journalists reporting about the life and death of Catholic leader Pope John Paul II, who died in April 2005. Also features two collections of resources for researching the pope, the Vatican, and Catholicism. From the Poynter Institute. Preventing Future Bridge Collapses: Protective Coatings May Hold Key
In the wake of the tragic bridge collapse in Minnesota and last year's shut down of an oil pipeline in Alaska due to corrosion, researchers are facing increased pressure to develop better protective coatings to help save aging infrastructures. Protective coatings and paints, such as epoxy resins and polyurethanes, are designed primarily for warding off corrosion in metal-based structures such as bridges, storage tanks and buildings. Study Yields Mixed Results On Potential For Pine Trees To Store Extra
Southern pines appear to grow and conserve water somewhat better in the carbon-dioxide-enriched atmosphere expected by mid-century, a Duke University study has found. However, any growth spurts appear to diminish over time, due at least in part to the kind of hot and dry weather that likely may become more common in the future. Thus, the researchers concluded, enhanced growth of pines may not constitute a long-term sink for human-produced carbon dioxide which might ameliorate global warming. Mechanism For The In-vivo Transport Of SiRNA
RNA interference, a natural mechanism that inhibits the gene expression of individual genes in eukaryotic cells, is a major topic in modern biology. However, their potential was usable to only a limited extent in mammals because the mechanism for the uptake of small RNAs was unknown up to now. Biologists have now clarified this, which also opens the door for therapies based on this mechanism. Neurons Found To Be Similar To U.S. Electoral College
A study has found that certain neurons, at one level, operate a little like the US Electoral College. The findings provide evidence supporting the "two-layer integration model," which attempts to explain how neurons integrate synaptic inputs. Each dendritic branch receives electrical inputs and decides on one signal to send the axon. The axon receives signals from the dendrites, much like electoral votes coming in from state elections, and a final decision is made. Statin Plus Cancer Drug Deliver Combo Punch To Brain Cancer Cells
Building on newly discovered genetic threads in the rich tapestry of biochemical signals that cause cancer, a Johns Hopkins Kimmel Cancer Center team has dramatically killed brain cancer cells by blocking those signals with a statin and an experimental antitumor drug. Eleanor &Harry: The Correspondence of Eleanor Roosevelt and Harry S. T
Facsimiles and transcriptions of the 1945-1959 correspondence between Eleanor Roosevelt and Harry S. Truman. The correspondence shows how "from a formal, often wary, political relationship developed also a strong friendship. Ultimately, Harry Truman designated Eleanor Roosevelt as his representative on the United Nations and 'First Lady of the World.'"Includes biographies, lesson plans, photos, and related links. A joint project of the Franklin D. Roosevelt Presidential Library and the Harry S. Truman Presidential Library.
