Urine odour test for bladder cancer 8 July 2013Last updated at 20:22 ET By Michelle Roberts Health editor, BBC News online Urine gives off a unique odour when cancer cells are present UK scientists have made a device that can "smell" bladder cancer in urine samples. It uses a sensor to detect gaseous chemicals that are given off if cancer cells are present. Early trials show the tests gives accurate results more than nine times in 10, its inventors told PLoS One journal. But experts say more studies are needed to perfect the test before it can become widely available. Each year around 10,000 people in the UK are diagnosed with bladder cancer. Doctors have been searching for ways to spot this cancer at an earlier stage when it is more treatable. And many have been interested in odours in urine, since past work suggests dogs can be trained to recognise the scent of cancer. Prof Chris Probert, from Liverpool University, and Prof Norman Ratcliffe, of the University of the West of England, say their new device can read cancer smells.

Canada train blast: Blame game over Lac-Megantic disaster 9 July 2013Last updated at 13:38 ET Continue reading the main story A rail firm and fire department appear to be pointing the finger at one another over a Canada oil train blast that has killed at least 13 people. Investigators say the tragedy may have been caused by a chain of events stemming from an earlier fire. Shortly after fire crews put out a blaze on the train, it experienced brake failure, ran away and exploded in the Quebec town of Lac-Megantic. About 40 people remain missing in the disaster zone. Some 1,200 of the 2,000 people evacuated from Lac-Megantic are being allowed home on Tuesday.

Cranberry Cranberries are a group of evergreen dwarf shrubs or trailing vines in the subgenus Oxycoccus of the genus Vaccinium. In some methods of classification, Oxycoccus is regarded as a genus in its own right. They can be found in acidic bogs throughout the cooler regions of the northern hemisphere. Cranberries are low, creeping shrubs or vines up to 2 metres (7 ft) long and 5 to 20 centimetres (2 to 8 in) in height; they have slender, wiry stems that are not thickly woody and have small evergreen leaves. Cranberries are a major commercial crop in certain American states and Canadian provinces (see cultivation and uses below). Since the early 21st century within the global functional food industry, raw cranberries have been marketed as a "superfruit" due to their nutrient content and antioxidant qualities.[dead link] Species and description Approximate ranges of the cranberries in sect. There are three to four species of cranberry, classified in two sections: Annual U.S.
Soursop Soursop is the fruit of Annona muricata, a broadleaf, flowering, evergreen tree native to Mexico, Cuba, Central America, the Caribbean, and northern South America, primarily Colombia, Brazil, Peru, Ecuador, and Venezuela. Soursop is also produced in some parts of Africa, Southeast Asia and the Pacific. It is in the same genus as the chirimoya and the same family as the pawpaw. The soursop is adapted to areas of high humidity and relatively warm winters; temperatures below 5 °C (41 °F) will cause damage to leaves and small branches, and temperatures below 3 °C (37 °F) can be fatal. The fruit becomes dry and is no longer good for concentrate. The flavour has been described as a combination of strawberry and pineapple, with sour citrus flavour notes contrasting with an underlying creamy flavour reminiscent of coconut or banana. Soursop is widely promoted (sometimes as "graviola") as an alternative cancer treatment. Cultivation Uses Properties Health Neurotoxicity
Should I ditch Android for Nokia's Lumia 1020? | Mobile Could Nokia's new 41-megapixel Lumia 1020 be the best smartphone for shutterbugs? I love taking pictures. But I can't tell you the last time I carried around a point-and-shoot camera. I almost exclusively use my smartphone for most of my picture taking needs nowadays. But to be perfectly honest, I am often disappointed in the images. This is why Nokia's new 41-megapixel Lumia 1020 sounds so appealing. In this edition of Ask Maggie, I offer my opinion on these questions. Dear Maggie, I am a Verizon Wireless customer and I'm looking for a new smartphone. One of the biggest issues for me is that I'm happy with Android, and I don't think I want to move to Windows Phone. What do you think? Thanks, MDG Dear MDG, First of all congratulations on the upcoming baby! Owning a big digital SLR is nice for getting some terrific photos. I have a smaller point-and-shoot camera, but even carrying that around is not as convenient as just using my smartphone to take quick snapshots. Is it worth it?
