Same-sex mating found in most common human fungal pathogen Candida albicans

Brown University researchers have discovered that Candida albicans, a human fungal pathogen that causes thrush and other diseases, pursues same-sex mating in addition to conventional opposite-sex mating.

Febit's DNA-capture method selected by NCGR to re-sequence 400 genes involved in childhood diseases

The National Center for Genome Resources (NCGR) has selected febit's DNA-capture method, HybSelect, to re-sequence the exons of genes involved in over 400 of the most devastating childhood diseases with the ultimate goal of developing genetic tests to detect carrier status for recessive genetic diseases in prospective parents.

Oxygen nanosensor could improve tumor imaging

A new material developed at the University of Virginia - an oxygen nanosensor that couples a light-emitting dye with a biopolymer - simplifies the imaging of oxygen-deficient regions of tumors. Such tumors are associated with increased cancer aggressiveness and are particularly difficult to treat.

'Nanobee' drug delivery to tumors

When bees sting, they pump poison into their victims. Now the toxin in bee venom has been harnessed to kill tumor cells by researchers at Washington University School of Medicine in St. Louis. The researchers attached the major component of bee venom to nano-sized spheres that they call nanobees.

Scientists study affect of carbon nanoparticles on fruit flies

Carbon nanoparticles are widely used in medicine, electronics, optics, materials science and architecture, but their health and environmental impact is not fully understood.

Nanotechnology helps scientists measure the forces that hold proteins together

Rice University physicists have written the next chapter in an innovative approach for studying the forces that shape proteins -- the biochemical workhorses of all living things.

Scientists create stem cells from developing sperm

The promise of stem cell therapy may lie in uncovering how adult cells revert back into a primordial, stem cell state, whose fate is yet to be determined. Now, cell scientists at the Johns Hopkins University School of Medicine have identified key molecular players responsible for this reversion in fruit fly sperm cells.

Potential new antibiotics tested in pinhead-sized worms

In an advance that could help ease the antibiotic drought, scientists in Massachusetts are describing successful use of a test that enlists pinhead-sized worms in efforts to discover badly needed new antibiotics. Their study appeared in ACS Chemical Biology, a monthly journal.

Research looks at health and environmental effects of exposure to nanoparticles

A new study raises the possibility that flies and other insects that encounter nanomaterial "hot spots," or spills, near manufacturing facilities in the future could pick up and transport nanoparticles on their bodies, transferring the particles to other flies or habitats in the environment.

3D science-based film opens at the Health Museum

Imagine exploring an alien world where odd creatures roam bizarre terrain in search of food. Then witness the attack and counterattack of viral bacteria at a cellular level. Now imagine it all in 3D!

Compound from coral offers hope fpr neuropathic pain

A compound initially isolated from a soft coral (Capnella imbricata) collected at Green Island off Taiwan, could lead scientists to develop a new set of treatments for neuropathic pain - chronic pain that sometimes follows damage to the nervous system.

New bio-hybrid materials could be used as sensors, catalysts, drug-delivery systems, more

Bacteria play a role in myriad industrial processes from fermentation to cleaning up environmental pollution. But floating freely in solution, the microbial cells constantly multiply, generating biomass that must be removed periodically, causing downtime. Additionally, the microorganisms cannot be localized to a specific region of interest.

Discovery of mechanism that protects somatic cells against the behaviour of germ cells

An IRB Barcelona research team discovers the mechanism that favors the correct separation of germ cells -- future ovules and sperm -- from the rest of the cells during embryonic development

Opportunities and risks posed by synthetic biology

The new research field of synthetic biology will, in the medium term, open up a great deal of potential for combining novel genetic methods with engineering principles. This will facilitate the development, not only of new vaccines and medicines, but also of fuels and new materials.

New journal devoted to gene therapy and human genetics

The Gene Therapy Review was first launched in 2008 as an online source of information on all aspects of gene therapy with sections comprising information on gene therapy research, news, disease targets, patient resources and companies offering services to the gene therapy community. It then further featured a clinical trials database detailing all gene therapy clinical procedures completed to date.

New chemical imaging technique could help in the fight against atherosclerosis

A new chemical imaging technique could one day help in the fight against atherosclerosis, suggests research published in the August 2009 edition of the Journal of the Royal Society Interface.

Dynamic, 3D pattern formation within protein-based gel

Modern regenerative medicine is on the lookout for implantable materials that can change as the surrounding tissue does, and two Stanford University researchers have made some new gel materials that do just that. Karin Straley and Professor Sarah Heilshorn have developed a method for preparing protein-based implant materials that can evolve with the changing needs of the host biological system. Not only can their new materials change in different ways at different times, they can do so at different places within the implant materials.

Spermatagonial stem cells can be directly converted into other cell types

Researchers have found a way to directly convert spermatogonial stem cells, the precursors of sperm cells, into tissues of the prostate, skin and uterus. Their approach, described this month in the journal Stem Cells, may prove to be an effective alternative to the medical use of embryonic stem cells.

Scientists combine two nanoparticles into one tiny package

Nanoparticles are being developed to perform a wide range of medical uses - imaging tumors, carrying drugs, delivering pulses of heat. Rather than settling for just one of these, researchers at the University of Washington have combined two nanoparticles in one tiny package.

Nanodiamonds hold promise for wound-healing applications

Bacterial infection is a major health threat to patients with severe burns and other kinds of serious wounds such as traumatic bone fractures. Recent studies have identified an important new weapon for fighting infection and healing wounds: insulin.
