Understanding the reinforcing ability of carbon nanotubes
A new article explores what is preventing the reinforcing ability of carbon nanotubes from being used in a ceramic matrix. Ever since their discovery, carbon nanotubes (CNTs) have been considered the ultimate additive to improve the mechanical properties of structural ceramics, such as aluminum oxide, silicon nitride and zirconium dioxide. Yet despite the remarkable strength and stiffness of CNTs, many studies have reported only marginal improvements or even the degradation of mechanical properties after these super-materials were added.

Heat waves becoming more prominent in urban areas, research reveals
The world’s urban areas have experienced significant increases in heat waves over the past 40 years, according to new research. These prolonged periods of extreme hot days have significantly increased in over 200 urban areas across the globe between 1973 and 2012, and have been most prominent in the most recent years on record.

Biomaterial coating raises prospect of more successful medical implants
A novel, bacteria-repelling coating material that could increase the success of medical implants has been created. The material helps healthy cells 'win the race' to the medical implant, beating off competition from bacterial cells and thus reducing the likelihood of the implant being rejected by the body.

Why do zebras have stripes? Temperature counts
One of nature's fascinating questions is how zebras got their stripes. A team of life scientists has found at least part of the answer: The amount and intensity of striping can be best predicted by the temperature of the environment in which zebras live.

Scientists home in on reasons behind cancer drug trial disappointment
Scientists have discovered a 'hidden' mechanism which could explain why some cancer therapies which aim to block tumor blood vessel growth are failing cancer trials. The same mechanism could play the role in the bacterial or viral septic shock -- e.g. in Ebola fever -- by destabilizing the blood vessels.

Shared symptoms of Chikungunya virus, rheumatoid arthritis may cloud diagnosis
A mosquito-borne virus that has spread to the Caribbean and Central and South America and has caused isolated infections in Florida often causes joint pain and swelling similar to that seen in patients with rheumatoid arthritis.

Skip the dip! Super Bowl team cities see spike in flu deaths
Having a team in the Super Bowl correlated to an average 18 percent increase in flu deaths among those over 65 years old, according to a study of health data covering 35 years of championship games.

Treating Cerebral Malaria: New Molecular Target Identified
A drug already approved for treating other diseases may be useful as a treatment for cerebral malaria, according to researchers who discovered a novel link between food intake during the early stages of infection and the outcome of the disease, identifying two molecular pathways that could serve as new targets for treatment.

Totality of trials data confirm Tamiflu reduces length of symptoms, complications, and hospital admissions from influenza
The most thorough analysis of oseltamivir (marketed as Tamiflu) data to date, including all available published and unpublished randomised treatment trials of adults, suggests that the antiviral drug shortens the duration of flu symptoms by about a day, compared to placebo, in adults with laboratory-confirmed influenza.
