Simple home spit test to spot deadly pre-eclampsia

... 'A salivary urate test is simple, non-invasive, quick and cheap and can be done at any time. As a metabolic test independent of blood pressure, it may obviate the need for hospital admission,' said retired hospital rheumatologist Brian Owen-Smith, who invented the test. The trial, which will eventual...

Anti-wrinkle compound causes pathological reaction in skin cells

...am revealed that the application of DMAE induces a quick and spectacular swelling of skin cell vacuoles called fibroblasts, which act as reservoirs and interface between the inside and the outside of the cell. In the hours following the application of DMAE, the researchers observed an important slowing ...

Biologists prove critical step in membrane fusion

...in the cell and fusion is complete. The process is quick because of hemifusion ?the vesicles are right there and ready to go." Wong and Wessel said that their findings might help scientists find new ways to deliver drugs to cells. If membrane-bound drugs can be induced to hemifuse with target cells ?rat...

FSU researchers determine a critical factor in workings of proteins

...ism." Mutations are one factor that can disrupt quick association between proteins and lead to disease, he said. "For example, Wiskott-Aldrich syndrome, a pediatric genetic disorder characterized by eczema, immune deficiencies and low blood-platelet counts, can be traced to mutations on the Wiskott-A...

Over a century after disappearing, wild elk return to Ontario

...re currently living in Ontario. Dr. Rosatte is quick to point out that the program faced many challenges. Many of the reintroduced elk did not survive long after being transferred, particularly due to wolf predation, illegal hunting and stress from the transfer process. However, the death rate is decre...

Fruit fly gene research may shed light on human disease processes

...t the two species are "close." Although he is quick to point out that the group's research has no short-term practical application, he believes down the road it has important implications for human health. "Scientists have been trying to understand how the sex of mosquitoes is determined, with an e...

Reversing cancer cells to normal cells

...o multiple, different types of cells. First, a quick primer on the shared characteristics of aggressive tumor cells and embryonic stem cells: Embryonic stem cells are pluripotent, meaning they are able to differentiate into any of the more than 200 cell types in the adult body. Which type of cell they ...

Breathing easy: When it comes to oxygen, a bug's life is full of it

..., which have a respiratory system built to provide quick access to a lot of oxygen, can survive for days without it. The insect respiratory system is so efficient that resting insects stop taking in air as they release carbon dioxide, according to research by Stefan K. Hetz of Humboldt University in Berli...

Fake pesticides threaten food safety

...CEO of the UK Crop Protection Association (CPA) is quick to point out that the UK is ahead of the game. Counterfeit products account for 3% of the UK market, compared to 5-7% in the EU. 'The CPA actively encourages enforcements to prevent illegal imports. We recommend that farmers buy pesticides from a rel...

Scientists design simple dipstick test for cocaine, other drugs

"The new sensors offer a quick and convenient test that can be utilized by first responders or emergency room staff to quickly screen individuals for a variety of drugs and other chemicals." Lu said. Aptamers are single-stranded nucleic acids that can bind to specific molecules ...

End of deforestation in view? Experts advance new way to size up global forest resources

...oor populations who burn wood to cook, sell it for quick cash, and clear forest for crops. Harvesting biomass for fuel also forestalls the restoration of land to nature. Through paper recycling and a growing reliance on electronic communication, people help the transition by lessening demand for wood pro...

Chemical tests of cell growth enter third dimension

...w each kind of cell reacts to the same dosage -- a quick way to detect a drug's potential side effects on the body. "The trick is to use one pump for everything, and control the fluid distribution though all the channels," Yang said. While he has worked out an initial design, he would like to join with a ...

Beyond the book: Software automates access to brain atlases

USC computer scientists have found a cheap, quick and copyright-respecting way to turn existing print brain atlases into multimedia resources. The software, now available in an experimental beta version for free download, is a robust and user-friendly interface that works on all the most popular com...

Molecular mechanism provides intra-cellular traffic signal

UCSD study reveals how plants respond to elevated carbon dioxide

...e leaf. In the presence of low carbon dioxide, a quick drumbeat was induced, but the stomata opened, rather than closed. Therefore, high carbon dioxide seems to prime the calcium sensors in the leaf. Jared Young, an assistant professor of biology at Mills College, who completed the study while he was a g...

Copying nature could save us energy, study shows

...roblems they are faced with. "Whilst we have been quick to see the potential for developing new kinds of products from nature, it is only now that we can see the potential for making energy savings too," said Professor Vincent. "Given the growing demands for improving our energy-efficiency and reducing t...

Hopkins scientists show hallucinogen in mushrooms creates universal 'mystical' experience

...behavior are grounded in biology." Griffiths is quick to emphasize the scientific intent of the study. "We're just measuring what can be observed," he says; "We're not entering into 'Does God exist or not exist.' This work can't and won't go there." In the study, more than 60 percent of subjects des...
