Vaccine for Ebola virus

Researchers have successfully tested Ebola vaccines in primates, triggering a cell-mediated response and producing effective protection. The candidates are now set to be tested on humans for the first time, offering hope for controlling outbreaks and protecting healthcare workers.

Team explains 'the wallpaper problem'

A team of researchers from MIT and CNRS studied the phenomenon of triangular tears in adhesives like tape and plastic sheets. They found that these tears arise from interactions between three properties: elasticity, adhesive energy, and fracture energy. The study has potential industrial applications in microtechnologies.

Green tea helps beat superbugs

Egyptian scientists have discovered that green tea boosts the effectiveness of antibiotics against superbugs by up to 99.99%, increasing the killing power of chloramphenicol and making 20% of drug-resistant bacteria susceptible to cephalosporin antibiotics.

3-D imaging -- first insights into magnetic fields

Scientists at HMI and University of Applied Sciences in Berlin have successfully visualized three-dimensional images of magnetic fields inside solid, non-transparent materials. By detecting changes in neutron spin rotation, the researchers can reconstruct a three-dimensional image of the magnetic field distribution within the sample.

Neurons hard wired to tell left from right

Researchers have identified neurons that form different spiral-shaped axons on the left and right sides of the brain, suggesting a possible explanation for brain asymmetry. The findings provide new insights into how the brain processes information and could lead to a better understanding of cognitive performance and social behavior.

Communicating your way to a healthy heart

A recent study from Temple University's School of Medicine found that regular communication with doctors can significantly lower the risk of cardiovascular disease. By using an internet-based health reporting system and regular clinic visits, participants were able to improve their blood pressure, blood lipid levels, and cardiovascular...
