Paris, Sept 21 : The European Space Agency (ESA) has embarked on a ‘Don Quijote’ mission that would chart out the trajectory of small asteroids to see if these rocky bodies are in line with a collision with Earth in the future.

The Don Quijote mission is a project based in two phases.

The first phase will see a spacecraft rendezvous with an asteroid and go into orbit around it. It would monitor the asteroid for several months, precisely determining its position, shape, mass and gravity field.

Washington, September 21 : A smart particle insulin release system that detects spikes in glucose and blood sugar levels, and releases insulin to counteract them has shown promising results in feasibility tests on animal models.

Researchers at The University of Texas School of Health Information Sciences at Houston have announced the findings of the pre-clinical test in the International Journal of Nanomedicine.

Washington, September 21: An animal study at Northwestern University in Chicago has shown how exposure to particulate matter leads to accelerated blood clotting and thrombosis, which can in turn cause heart attacks and stroke.

Particulates, chemical or biological agents that change the natural characteristics of the atmosphere, cause air pollution.

Washington, Sept 21: Droughts would make the verdant Amazon rainforest even greener, a new study by a team of researchers from the University of Arizona, US, has revealed.

Washington, Sept 20 : Phosgene, put to devastating use during the First World War, is present in significant quantities in the atmosphere, a new study by a US-Canadian research team has revealed.

Phosgene was stockpiled in military arsenals well after the Second World War, but its continued presence in the atmosphere today is due to man-made chlorinated hydrocarbons used in the chemical industry.

Washington, Sept 20 : Researchers at the Massachusetts Institute of Technology (MIT) have created a device that would lighten the burden for soldiers and others who carry heavy packs and equipment.

Their invention, known as an exoskeleton, can support much of the weight of a heavy backpack and transfer that weight directly to the ground, effectively taking a load off the back of the person wearing the device.
