Surprise! Young Stellar Clusters Found In Old Galaxy
Combining data from the NASA/ESA Hubble Space Telescope (HST) and the ESO Very Large Telescope (VLT), a group of European and American astronomers have made an unexpected major discovery.

Systematic Pattern Of Rainfall Across U.S. Discovered
Meteorologists have long known that summer thunderstorms and heavy rains are difficult to predict. They pop up quickly and disappear within a few short hours.

Knapweed Chemical May Be Basis Of 'Green' Herbicide
Scientists have speculated for decades that spotted knapweed is able to spread over large areas because of a secret weapon -- an ability to release a chemical that kills surrounding plants.

Structure Of Key Interbacterial Chat Protein Solved
A decade after microbiologists began to suspect that many groups of bacteria can communicate -- by releasing and detecting chemical pheromones to gauge their population density -- the molecular structure of a key protein in this interbacterial communication has been solved.

Cells Flip Molecular Switch Before Sending A Message
It's a wonder cells make it through the day, with the barrage of cues and messages they receive and transmit to direct the most basic and necessary functions of life.

Brown Algae Phylogeny Turned Completely Upside Down
According to fellow phycologists, algae expert Stefan Draisma from the Leiden University in The Netherlands has turned brown algae phylogeny completely upside down.


Antivaccination Websites Rely On Emotion, Not Evidence
Websites that question the safety and benefits of immunizing children rely heavily on emotional appeals rather than scientific evidence.

Study Throws New Light On How Gene Switches Operate
Faulty regulation of genes is a common basis of many human diseases, including many cancers.

Linking Microscope Images To Quantitative Information
A team of computer scientists working with cell biologists at Lawrence Berkeley National Laboratory has created BioSig, a web-based bioinformatic system that links collections of microscope images to a wide variety of quantitative experimental data.

Explaining False Negative Results On Some Pap Tests
Some women may be getting false negative results on their routine Pap tests -- the traditional method to detect cervical cancer early -- because aberrant tissue changes can keep abnormal cells from being picked up during the exam, according to a study released today.

Change In One Base Pair Can Create A Typhoid Mary
Salmonella enterica causes approximately 16 million cases of typhoid fever worldwide, killing around 500,000 people per year.

Romans Preferred Small-Scale Systems For Drainage
Contrary to common opinion, the Romans had several systems for the supply and drainage of water. And they preferred small-scale provisions such as cesspits, wells and rainwater tanks.
