Small amounts of oil leave a fluorescent sheen on polluted water. Oil sheen is hard to remove, even when the water is aerated with ozone or filtered through sand. Now, a University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles [...]

It`s no bigger than a stamp packet but it has the potential to allow rapid development of a new generation of drugs and genetic engineering organisms, and to better control in-vitro fertilization.
Engineering researchers at McMaster University have fabricated a palm-sized, automated, micro-injector that can insert proteins, DNA and other biomolecules into individual cells at volumes [...]

A novel method of detection of cervical cancer cells has been developed by Clarkson University Professor Igor Sokolov`s group, an affiliate of the University`s Nanoengineering and Biotechnology Laboratories Center (NABLAB).
The group`s paper is published in Small.
Methods for detection of cancer cells are mostly based on traditional techniques used in biology, such as visual identification of [...]

Scientists have shown that tiny crystals found inside bacteria provide a magnetic compass to help them navigate through sediment to find the best food.
Researchers say their study could provide fresh clues to explain biomagnetism – a phenomenon in which some birds, insects and marine life navigate using the magnetic field that encompasses the Earth.
The study [...]

Indulging in just one small chocolate truffle can induce cravings for more sugary and fatty foods—and even awaken a desire for high-end status products, according to a new study in the Journal of Consumer Research.
In a study that examined goals and behavior in consumers, authors Juliano Laran (University of Miami) and Chris Janiszewski (University of [...]

MIT researchers have created a microbial ecosystem smaller than a stick of gum that sheds new light on the plankton-eat-plankton world at the bottom of the aquatic food chain.
The work, reported in the January print issue of American Naturalist, may lead to better predictions of marine microbes` global-scale influence on climate.
Through photosynthesis and uptake of [...]

MIT researchers have shown how a cell motor protein exerts the force to move, enabling functions such as cell division.
Kinesin, a motor protein that also carries neurotransmitters, "walks" along cellular beams known as microtubules. For the first time, the MIT team has shown at a molecular level how kinesin generates the force needed to step [...]

As most American families sit down to Thanksgiving dinner, a University of British Columbia researcher is revealing how one of the largest animals on earth feasts on the smallest of prey – and at what cost.
Some large marine mammals are known for their extraordinarily long dive times. Elephant seals, for example, can stay underwater for [...]

In human relationships, a certain "spark" often governs whether we prefer one person to another, and critical first impressions can occur within seconds. A team lead by Johns Hopkins researchers has found that cell-to-cell "friendships" operate in much the same way and that dysfunctional bonding is linked to the spread of cancer.
"Bonding between cells has [...]

Microvesicles – tiny membrane-covered sacs – released from glioblastoma cells contain molecules that may provide data that can guide treatment of the deadly brain tumor. In their report in the December 2008 Nature Cell Biology, which is receiving early online release, Massachusetts General Hospital (MGH) researchers describe finding tumor-associated RNA and proteins in membrane [...]
