Crawling the Web: Alzheimer's and p53

Everyday, Scientist Live turns its eyes to the Web around it and highlights news and research across the Internet. Today we look at Alzheimer's disease and the human p53 regulator.

Personalised HIV therapy

Researchers are using minute, naturally occurring proteins called zinc fingers to engineer T cells to one day treat AIDS in humans.

Transgenic and Organic Agriculture

The cultivation of genetically modified maize has caused a drastic reduction in organic cultivation of this grain and is making their coexistence practically impossible.

Heavy babies arthritis risk

People who have a birth-weight over 10 pounds are twice as likely to develop rheumatoid arthritis when they are adults compared to individuals born with an average birth-weight.

Instant nutrition in cassava

Scientists have determined how to fortify the cassava plant with enough vitamins, minerals and protein to provide a day's worth of nutrition in a single meal.

Cellular cannibalism

Scientists have found that autophagy can have a down side, destroying the pancreas by prematurely activating a digestive enzyme.

Making stem cells feel at home

Researchers have manipulated mouse brain stem cells programmed to join the neuronal network into becoming support cells instead.

Causes of homosexuality studied

Homosexual behaviour is largely shaped by genetics and random environmental factors, according to findings from the world's largest study of twins.

Drought tolerance in potatoes

Food scientists are examining the genes for drought tolerance traits in several native Andean potato landraces.

Mate choice in plants

Flowering plant pollination systems are clever devices for attracting pollinators like birds, ants, and insects, but there are also mechanisms for keeping out unwanted pollen.

The 21st century tomato

The revolution in genomics has made it possible to study the numerous pathways and regulatory networks-systems--that operate to produce a desirable fruit.

Evolution of fruit size in tomato

Domesticated tomatoes can be up to 1000 times larger than their wild relatives. How did they get so big?

Crawling the Web: Epidemic monitoring

Everyday, Scientist Live turns its eyes to the Web around it and highlights news and research across the Internet. Tuesday's spotlight studies offer new findings in epidemic monitoring.

Novel approach to Leishmaniasis

Dr. Silvia Uliana and her colleagues found that Tamoxifen, a drug used to fight breast cancer, offers effective treatment of Leishmaniasis at decidedly less physical cost to the patient.

Very small, very clear

At the core of TIGA, an imaging robot scans the tissue slices and displays them on the monitor for researchers at ultra high resolution and in various planes.

Not so good weekends

Recent research suggests that while we may enjoy weekends, they prove detrimental to weight loss regiments. Saturdays are the worst.

Finding soil water

Researchers investigate the potential of an innovative soil water simulation model to improve crop management.

Pesticides Persist in Ground Water

Numerous studies over the past four decades have established that pesticides can move downward through the unsaturated zone to reach the water table at detectable concentrations.

Smokers prone to back pain

As if lung cancer, shortness of breath, bad breath, bad teeth, and infertility aren't enough, researchers add back pain to smoking's lengthy list of side effects.

Topsy-turvey world of physics

Researchers at Delft University of Technology in The Netherlands have developed a technique for generating atom clusters made from silver and other metals.
