Science captures the essence of fruit

...While many biofermented compounds will undoubtedly end up in non-food consumer products such as make-up or household cleaners, Dr Newcomb is confident they will also play a role in the expanding health food market. "Researchers are finding ever greater numbers of foods and food compounds that can enhan...

Researcher gives hard thoughts on soft inheritance

"In this particular instance that says what you're getting fed in the womb influences your phenotype ?physical and physiological attributes." Another study showed that early grooming and nurturing...

UCSD researchers develop 'smart petri dish'

...of the reasons many drugs clear animal testing but end up toxic in patients. This type of sensor could help us predict human liver responses without patient exposure." "Because the Smart Petri Dish gives a continuous readout of cell damage," she adds, "this type of sensor could also be very useful for ...

Non-coding RNAs help silence the mammalian transcription

...n the mouse, a cluster of nine genes on the distal end of the number 7 chromosome is imprinted. Dr. Tilghman and colleagues made a series of targeted alterations to ascertain which sequences are responsible for their paternal-specific silencing. The researchers show that this imprinted gene silencing req...

Researchers unveil strategy for creating actively-programmed anti-cancer molecules

...of these women will die of the disease-usually the end result of metastasis. The therapeutic use of monoclonal antibodies has expanded rapidly over the last several years precisely because of their long half-life, combined with their overall lack of toxicity and the fact that they can be easily designe...

Federal testing for mad cow disease a failure, law review editor says

...hese incidents underscore the need for the USDA to end its head-in-the-sand approach and begin "a mix of mandatory and voluntary testing to ensure the largest possible number of cattle are tested, while working to open foreign markets for American beef on the basis of the reliability of that testing," Be...

Ultra low-dose estrogen shown safe for post-menopausal women

...dy, after one year, and after two years. At the end of the study, there was no difference between the two groups in either cognitive abilities or health-related quality of life. "The results are very reassuring, because it suggests that women can use this patch without harm for two years," says Yaff...

Combined treatment extends life expectancy for lung cancer patients

...nt of tumors recur within six to 12 months. By the end of this study, 24 percent of patients treated with ablation and radiation had recurrences at an average of 44 months. While there was an increased recurrence rate in larger tumors ?33 percent recurred at an average of 34 months ?the overall survival ...

UN review shows need to halt destructive fishing practice

Marine scientists and developing countries have called for a moratorium against high seas bottom trawling, which targets deep sea fish species such as orange roughy by dragging heavy gear across the seafloor, causing widespread and pot...

Experimental RNA-based drug kills prostate cancer cells effectively and safely

... for a total of 10 injections over 20 days. By the end of the study, the tumors in the 10 treated mice had shrunk two-fold in volume, while the tumors in the 10 control animals had more than tripled in size. "The animals themselves showed no signs of side effects," Giangrande said. The scientists ca...

Completed genome set to transform the cow

...CSIRO's Dr Ross Tellam, says the new map marks the end of the sequencing phase of the project, with the focus now on analysing the available data. "This is very valuable information," Dr Tellam says. "We could potentially achieve as much improvement in cattle breeding and production in 50 years as we h...

Bumble bees can estimate time intervals

When nectar was delivered after either of two different intervals, bees could often time both intervals simultaneously. This research shows that the biological foundations of time perception may be found in...
