Alzheimer's-associated protein may be necessary

Amyloid-beta protein - the primary constituent of the plaques found in the brains of Alzheimer's disease patients - may be part of the body's first-line system to defend against infection.

Oestrogen and breast cancer

A new study is providing insight into how oestrogen fuels many breast cancers, and researchers say the findings could lead to new cancer-fighting drugs.

Key enzyme unlocked using 'cool' method

A team of scientists - using a new cooling method they created - has uncovered the inner workings of a key iron-containing enzyme, a discovery that could help researchers develop new medicines or understand how enzymes repair DNA.

Studying protein folding

A new technique to study protein dynamics in living cells has been created and evidence yielded from the new method indicates that an in...

Flightless mosquitoes fight dengue fever

A new strain of mosquitoes in which females cannot fly may help curb the transmission of dengue fever, according to UC Irvine and British scientists.

RNA molecule with big implications for life's origins

An extremely small RNA molecule created a team of researchers can catalyse a key reaction needed to synthesise proteins, the building blocks of life.

Gene regulation: Can we stomach it?

Using a newly developed sequencing technique, the researchers discovered 60 small ribonucleic acids in the genome of the Helicobacter pylori human pathogen.

Pancreatic oncogene discovered

Researchers have found that PKC-iota, an oncogene important in colon and lung cancers, is over-produced in pancreatic cancer and is linked to poor patient survival.

Early diagnostic biomarker for Alzheimer's

Researchers have found that elevated cerebrospinal fluid levels of phosphorylated tau231 may be an early diagnostic biomarker for Alzheimer's disease in healthy adults.

The helpful sound of melanoma

Researchers are studying how photoacoustics, or a laser-induced ultrasound, could help scientists locate the general area of the lymph node where melanoma cells could be residing.

How nerve cells grow

A brain researcher has discovered the workings of a process that had been completely overlooked until now, and that allows nerve cells in the brain to grow and form complex networks.

Enzyme deficiency protects hepatitis C patients

Scientists have discovered two genetic alterations linked to a benign enzyme condition that keep some patients hepatitis C develop hemolytic anaemia-free.

How the cholera bacteria becomes infectious

In a new study, researchers describe the structure of a protein called ToxT that controls the virulent nature of Vibrio cholerae, the bacteria that causes cholera.

Switch turns on the spread of cancer

Researchers describe the discovery of a specific protein called disabled-2 (Dab2) that switches on the process that releases cancer cells from the original tumour and allows the cells to spread and develop into new tumours in other parts of...

Pathway sheds light on cystic fibrosis

In a study that could lead to new therapeutic targets for patients with the cystic fibrosis, a research team has identified a defective signaling pathway that contributes to disease severity.

Proteins cover blood type blind spot

A set of proteins found in our intestines can recognise and kill bacteria that have human blood type molecules on their surfaces, scientists have discovered.

Prion protein in cell culture

The fatal brain disease Creutzfeldt-Jakob in humans, BSE in cattle and scrapie in sheep are so-called prion diseases, whereby one of the...

HPV vaccines may reduce a wide range of genital diseases

High-coverage human papillomavirus vaccinations among adolescents and young women may result in a rapid reduction of genital warts, cervical cell abnormalities, and diagnostic and therapeutic procedures, researchers report.

Energy release during infection

Researchers have measured the energy associated with the expulsion of viral DNA, a pivotal discovery toward fully understanding the physical...

Brain diseases linked by toxic form of neural protein

For the first time, researchers have found that three different degenerative brain disorders are linked by a toxic form of the same protein.
