CLAMP: A newly discovered protein that regulates genes

They say a good man is hard to find. Were it not for a newly discovered protein, the X chromosome of a male fruit fly could never be found by a gene-regulating complex that male flies need to develop and survive. And that case is just one example of what the new finding means. More generally, the research provides biologists with a model of how proteins that govern gene transcription find their targets on chromosomes, a process that's essential to healthy cell function and sometimes implicated in disease.

Researchers use peels of apples and tomatoes to purify water

One of the most crucial problems affecting the world today is the scarcity of potable water. In a bid to make clean water available at low cost, Mr Ramakrishna Mallampati, a PhD candidate at the National University of Singapore, experimented with water treatment techniques using materials that are easily available, and came up with novel ways to purify water using the peels of apples and tomatoes.

Researchers develop new drug delivery technique for diabetes treatment

Researchers have developed a drug delivery technique for diabetes treatment in which a sponge-like material surrounds an insulin core. The sponge expands and contracts in response to blood sugar levels to release insulin as needed. The technique could also be used for targeted drug delivery to cancer cells.

Some strains of avian H7N9 influenza develop resistance to antiviral drugs

Some strains of the avian H7N9 influenza that emerged in China this year have developed resistance to the only antiviral drugs available to treat the infection, but testing for antiviral resistance can give misleading results, helping hasten the spread of resistant strains.

Study explores mechanisms of chemotherapy-induced neurological side effects

Chemotherapy is one of the primary treatments for cancer. However, one of the most disturbing findings of recent studies of cancer survivors is the apparent prevalence of chemotherapy-associated adverse neurological effects, including vascular complications, seizures, mood disorders, cognitive dysfunctions, and peripheral neuropathies.

Saltwater-treatment for cystic fibrosis: an interview with Matthew Allen, Program Director at Cambridge Consultants

A group of Australian researchers, back in 2006, noted that there was a link between the severity of cystic fibrosis between sufferers who surfed, and sufferers who did not surf – and obviously Australia is a good place to spot that.

Study suggests patient's neurons may be altered in different ways, although resulting disease is same

Epilepsy, irregular heartbeats and other conditions caused by malfunctions in the body's nerve cells, also known as neurons, can be difficult to treat. The problem is that one medicine may help some patients but not others.
