Dr. Gang Zheng and a team of biomedical researchers have discovered a "smart" organic, biodegradable nanoparticle that uses heat and light in a controlled manner to potentially target and ablate tumours with greater prec...

The percentage of Hispanics in Texas without health insurance has dropped by 30 percent since the Affordable Care Act went into effect, but almost one-third of Hispanic Texans ages 18 to 64 remain uninsured, shows a new ...

A new benchmark for generating the most primitive type of stem cell has been described by scientists in a new report. While stem cells--cells that have the potential to differentiate into other types of cells--exist in a...

Though the West African Ebola outbreak that began in 2013 is now under control, 23 countries remain environmentally suitable for animal-to-human transmission of the Ebola virus. Only seven of these countries have experie...

If you had heart disease risk factors, such as high blood pressure, before your first stoke, your risk of suffering subsequent strokes and dementia long after your initial stroke may be higher. Taking good care of your h...

Researchers recently made the surprising discovery that a special class of materials called "hyperuniform materials" can be both dense and transparent. This work demonstrates a new way to control light and could lead to ...

An international team of ecologists has identified the bat species with the greatest potential to harbor filoviruses -- a family that includes Ebola virus. The researchers suggest that areas where many of these species o...

Researchers have identified cells that provide 'safe houses' for the human immunodeficiency virus during antiretroviral therapy. HIV needs to be "housed" in a cell, a safe haven, so to speak, to live and replicate, expla...

Despite recent achievements in the development of cancer immunotherapies, only a small group of patients typically respond to them. Predictive markers of disease course and response to immunotherapy are urgently needed.

Scientists have created an algorithm that can identify drug combinations to treat fungal infections that have become resistant to current drug treatments. This new study represents a strategy for treating complex disease...

Researchers have developed a method to measure how the brain responds to electrical stimulation and use the response to maximize efficacy of deep brain stimulation (DBS) -- a therapy that has been successfully used to tr...

The major symptom of severe dengue disease is leakage of blood plasma out of small blood vessels, which can lead to shock and death. A study now suggests that the dengue virus protein NS1 can disrupt the innermost layer ...

Researchers report a new quality-control checkpoint function in developing B cells, cells that produce antibodies to protect the body from pathogens.

Every time you move around, you are turning on genes in your brain. A study in mice shows that if such genes get stuck in the "on" position, the consequences can include faulty brain wiring that affects learning and memo...

A team of researchers has identified novel therapeutic monoclonal antibody candidates isolated from Zika-infected patients and new strategies for Zika virus diagnostics. A new article describes for the first time an in-d...

The current Zika epidemic in Latin America is likely to burn itself out within three years, suggests new research. The Zika virus is carried by the Aedes aegypti mosquito, but the team cautioned any large-scale governmen...

Unexpectedly, ducklings recognise and remember relationships between "same" or "different" objects and colours, showing they can grasp abstract concepts

Works of art by masters like Rembrandt may have harnessed the power of light to create awe-inspiring, realistic paintings. This being Physics Buzz, artistic techniques are not really our specialty. However, it's worth a ...

A team of biomedical researchers has discovered a 'smart' organic, biodegradable nanoparticle that uses heat and light in a controlled manner to potentially target and ablate tumors with greater precision.

Indiana University researchers have created a virtual tissue model of diabetes in the eye that shows precisely how a small protein that can both damage or grow blood vessels in the eye causes vision loss and blindness in...

Osteonecrosis or 'bone death' of the femoral head is a disease caused by interruption of blood flow in the hip bone. Patients experience pain and the bone and surrounding joint collapse. Many patients are under the age o...

Scientists have developed a robust method for characterizing human embryonic stem cells and their potential for medical applications.
