Demand for alternative sweeteners are increasing by 8% a year

The demand for alternative sweeteners to sugar is increasing at a rate of 8% per year. The market is showing more and more interest in natural sweeteners compared to synthetic ones. This has been reflected in a study carried out by researchers at the Universidad Miguel Hernández (UMH) in Elche, Alicante.

Fruit fly avoidance mechanism could lead to new ways to control pain in humans

At first, fruit flies eat like horses. Hatching inside over-ripe fruit where they were laid, they feed wildly in the sugar-rich environment until nature sends them an offer they can't refuse. To survive, they must leave the fruit, wander off and burrow into the earth where they avoid food as if it were poison. Only then can the larvae grow and hatch into flies that will take wing to lay their own eggs.

Scientists identify key roadblock to gene expression

A team of scientists has provided, for the first time, a detailed map of how the building blocks of chromosomes, the cellular structures that contain genes, are organized in the fruit fly Drosophila melanogaster. The work identifies a critical stop sign for transcription, the first step in gene expression, and has implications for understanding how the AIDS virus regulates its genes. The findings will be published in the 15 May 2008 issue of the journal Nature

New key mechanism in cell division discovered

Scientists at the IFOM-IEO Campus have revealed the function of a protein that is indispensable for passing on an accurate copy of the genome from mother to daughter cells. This study, published in Cell, opens up new avenues of research to reduce the toxicity of chemotherapy in the treatment of cancer.

Nitrates in vegetables protect against gastric ulcers

Vegetables that are rich in nitrates protect the stomach from damage. This takes place through conversion of nitrates into nitrites by the bacteria in the oral cavity and subsequent transformation into biologically active nitric oxide in the stomach. The Swedish researcher Joel Petersson has described the process, which also means that antibacterial mouthwashes can be harmful for the stomach.

New study raises questions about prostate cancer therapies targeting insulin-like growth factor receptor

Therapies under development to treat prostate cancer by inhibiting the ability of insulin-like growth factor (IGF-1) to activate its target receptor could have unexpected results especially if a major tumor suppressor gene - p53 - is already compromised, according to new research by investigators at Fred Hutchinson Cancer Research Center.

New drug added to chemo kills off residual breast cancer stem cells

New research says chemotherapy often fails to totally eliminate breast cancer because it does not knock out breast cancer stem cells.

Getting to the roots of breast cancer

The lesson learned in eradicating dandelions from your yard could apply in treating breast cancer as well, said researchers from Baylor College of Medicine in Houston in a report that appears online today in the Journal of the National Cancer Institute.

AMPK signaling helps explain how cell growth is inhibited when nutrients are low

A team of scientists at the Salk Institute for Biological Studies think they know how many-if not most-living organisms answer this question. They recently showed that when food supplies dwindle, mammals, fruitflies, or frogs probably activate the same ancient cell signaling pathway in order to conserve energy.

Chemotherapy causes delayed severe neural damage

Cancer treatment with chemotherapeutic agents is often associated with delayed adverse neurological consequences - an occurrence often referred to as "chemobrain" - that may compromise the quality of life of a proportion of cancer survivors.

Discovery of fundamental mechanism of how tumour cells communicate

A new fundamental mechanism of how tumour cells communicate has just been discovered by the team of Dr. Janusz Rak at the Research Institute of the McGill University Health Centre (MUHC) in collaboration with Dr Guha from the University of Toronto.

New method for testing treatments for Chagas' disease

Chagas' disease is a tropical parasitic sickness that currently affects more than 16 million people, with a staggering 100 million at risk, largely in the tropical areas of South and Central America. And yet the main drug used to treat the disease is highly toxic and causes serious side effects.

Chronic inflammation triggers cell fusions that could protect neurons

Chronic inflammation triggers bone marrow-derived blood cells to travel to the brain and fuse with a certain type of neuron up to 100 times more frequently than previously believed, according to a new study from the Stanford University School of Medicine.

Cutting-edge surgical training facility to open at the University of Sydney

A new facility for the training of the next generation of microsurgeons in both molecular biology and advanced surgical techniques will be officially opened by the Governor of NSW, Her Excellency Professor Marie Bashir AC CVO, at the University of Sydney on Tuesday 22 April.

The mechanism of phosphorus as a cardiovascular risk factor in chronic kidney disease

The estimated 19 million Americans living with chronic kidney disease (CKD) face a high risk of death from cardiovascular disease. Recent studies have shown that a main source of this cardiovascular risk is CKD patients' high levels of blood phosphate.

Scientists solve arsenic's cancer paradox

Cancer Research UK scientists have discovered how arsenic works as an effective treatment for leukaemia - according to a report in Nature Cell Biology.

Discovery of gene involved in blood stem cell replication, movement

Researchers at the Joslin Diabetes Center have identified a gene that is responsible for the division and movement of marrow-derived, blood-forming stem cells, a finding that could have major implications for the future of bone marrow and blood cell transplantation.
