Camera-phone uses blood, saliva samples to diagnose disease

Researchers at the University of California, Berkeley, have developed a "prototype camera-phone mounted with a microscope" that can "magnify and photograph blood or saliva samples" for diagnosing diseases, the Canadian Press/Google.com reports.

Swine flu vaccine trials begin in Australia as death toll tops 700

As Australian scientists embark on the first trials of a swine flu vaccine the World Health Organisation (WHO) has announced that the H1N1 virus (swine flu) has now killed more than 700 people around the world since the outbreak began four months ago.

Experts warn about electronic cigarettes

The U.S. Food and Drug Administration today announced that a laboratory analysis of electronic cigarette samples has found that they contain carcinogens and toxic chemicals such as diethylene glycol, an ingredient used in antifreeze.

Migrant neuron: New imaging studies reveal mechanics of neuron migration

The development of the brain proceeds a little like the European settlement of North America. The earliest pioneers settled on the east coast with subsequent waves of settlers forming communities further and further westward. In cortical regions of the developing brain, generations of young neurons undergo a staged migration as well, with the earliest-born cells staying relatively close to their birthplace and subsequent generations traveling further, ultimately stratifying into six neuronal layers in the mature brain. Now, for the first time, imaging studies have identified the "motors" that propel a unique form of cell migration that creates these layers that

Miglustat shows promise for cystic fibrosis

Miglustat is a drug currently under phase 2 clinical trials on patients suffering from cystic fibrosis (1). Its potential for treating the disease was discovered in 2006 thanks to the work of Frédéric Becq's team at the Institute of Cell Physiology and Biology (CNRS/Université de Poitiers), funded by the associations Vaincre la Mucoviscidose, MucoVie66, La Pierre Le Bigaut and ABCF2.

New hope for the global iron deficiency problem

According to the World Health Organization, approximately two billion people suffer from iron deficiency. They tire easily, experience problems in metabolizing harmful substances in their bodies and eventually suffer from anemia.

New nanoparticles could revolutionize therapeutic drug discovery

Understanding the structure of proteins is a vital first step in developing new drugs, but to date, researchers have had difficulty studying the large number of proteins that are normally embedded in the cell membrane, a family of proteins that includes those involved in cancer-related signaling processes.

Airlines blocking travellers suspected of having swine flu

According to the World Health Organization (WHO) the H1N1 influenza A pandemic (swine flu) has killed around a total of 430 people and as health officials worldwide grapple to deal with rapid rise in the number of cases, airlines in Britain are blocking travellers suspected of having swine flu.

New discovery on DNA repair mechanism

Researchers at Washington University School of Medicine in St. Louis have shed new light on a process that fixes breaks in the genetic material of the body's cells. Their findings could lead to ways of enhancing chemotherapy drugs that destroy cancer cells by damaging their DNA.

Depression and stress worsen childhood asthma

Young people with asthma have nearly twice the incidence of depression compared to their peers without asthma, and studies have shown that depression is associated with increased asthma symptoms and, in some cases, death.

WHO gives up counting swine flu cases

In its latest briefing on the H1N1 influenza A pandemic (swine flu), the World Health Organisation (WHO) says the unprecedented speed of the spread of the virus means reporting requirements and the data needed for risk assessment, both within affected countries and at the global level, are changing.

"Drops" of gold that burn tumors

At a technical breakfast, Romain Quidant presented his research into the detection and treatment of cancer using gold nanoparticles illuminated with laser light. Quidant, who was recently awarded the Fresnel Prize 2009 that recognizes the highest level of excellence amongst emerging researchers in the field of photonics, is an ICREA researcher at the UPC's Institute of Photonic Sciences (ICFO) and a fellow of the Cellex Foundation Barcelona.

Turmeric spice and vitamin D may help clear amyloid plaques found in Alzheimer's

UCLA scientists and colleagues from UC Riverside and the Human BioMolecular Research Institute have found that a form of vitamin D, together with a chemical found in turmeric spice called curcumin, may help stimulate the immune system to clear the brain of amyloid beta, which forms the plaques considered the hallmark of Alzheimer's disease.

Scientists report new process for producing potentially safer form of acetaminophen

Scientists in Louisiana are reporting development of a process for producing large batches of a new and potentially safer form of acetaminophen, the widely used pain-reliever now the source of growing concern over its potentially toxic effects on the liver.

WHO recommends vaccine makers move forward in mass production of H1N1 vaccine

"Saying the new H1N1 [swine flu] virus is 'unstoppable', the WHO gave drug makers a full go-ahead to manufacture vaccines against the pandemic influenza strain on Monday and said healthcare workers should be the first to get one," Reuters reports (Fox, 7/14).

Discovery of brain-protecting protein

Johns Hopkins researchers have discovered a novel protein that can protect brain cells by interrupting a naturally occurring "stress cascade" resulting in cell death.

Researchers grow immature egg cells in the laboratory for 30 days - could sustain cancer patients’ fertility

Researchers funded by the National Institutes of Health have completed a critical first step in the eventual development of a technique to retain fertility in women with cancer who require treatments that might otherwise make them unable to have children.

Overcoming the big ‘nanotech’ challenges

Whether in the fields of medicine, sustainable energy supply or environmental protection, without making use of nanotechnology we will not be capable of overcoming the challenges which the future presents. In parallel with these efforts, though, it is essential that we examine the new technology very carefully for potential risks, such as those presented by free nanoparticles.

By manipulating oxygen, scientists coax bacteria into a wave

Bacteria know that they are too small to make an impact individually. So they wait, they multiply, and then they engage in behaviors that are only successful when all cells participate in unison. There are hundreds of behaviors that bacteria carry out in such communities. Now researchers at Rockefeller University have discovered one that has never been observed or described before in a living system.
