Radiation

The data was collected by NASA's Van Allen Probes, seen here in an artist's rendition (Ima...

Back in October 2013, two NASA probes were in the perfect position to observe a solar wave as it hit Earth’s magnetic field, gathering data on the event. That data has now been analyzed by teams of scientists at MIT’s Haystack Observatory and the University of Colorado, revealing the process by which harmful, high-speed particles are generated in Earth’s radiation belts.  Read More

The technique uses a small device containing a reservoir of chemotherapy that can be eithe...

Further to a list of side effects ranging from mildly unpleasant to just plain awful, the scattergun nature of chemotherapy often sees healthy tissue damaged along with the cancerous cells. Attacking these cancer cells with better precision would lead to more effective treatments and reduce harmful side effects, and has been a primary objective for researchers. Among this group is a team of scientists that has developed a way of administering cancer-fighting chemicals using an electric field that is claimed to enable a highly-targeted form of treatment.  Read More

Researchers have uncovered a new method that has the potential to greatly enhance the effe...

Scientists from Case Western Reserve University's School of Medicine have discovered a potential treatment that may steer cancer cells toward their own destruction. The study focused on a particular gene that was found to influence levels of a tumor-fighting protein called 53BP1, the heightened presence of which makes cancer cells more vulnerable to existing forms of treatment.  Read More

3D printing models of tumors and their surrounding organs could help specialists to delive...

Administering the correct dosages to fight cancerous tumors can be a difficult balancing act. Too much of the radioactive drugs can cause harm to healthy tissue, but not enough will see the cancer cells survive and continue to spread. But a new technique developed at The Institute of Cancer Research in London may afford doctors an unprecedented level of accuracy in performing radiotherapy, using 3D-printed replicas of a patient’s organs and tumors to better determine how much radiation a tumor has received.  Read More

A new study by NASA intends to examine the detrimental effects of microgravity on the immune system, by studying the blood of rats and blue mussels over the course of a prolonged stay aboard the International Space Station (ISS). The experiments, TripleLux A & TripleLux B, will be transported to the station by consecutive SpaceX commercial resupply missions. It is hoped that the results of the study could potentially inform future treatment options for immune system deficiencies both in space and on Earth.  Read More

A European Space Agency experiment aboard the International Space Station suggests that space travelers may have less to worry about when it comes to radiation ... thanks to a phantom. Called the Matroshka, the "phantom" is a plastic mannequin that is the key component of the first comprehensive study of the effects of radiation on astronauts on long-term space missions that indicates that the hazard may not be as severe as previously thought.  Read More

A natural shield has been found to protect the Earth from 'killer electrons'

The idea of putting a Star Trek-like force field around the entire Earth seems like the fodder for a fairly silly science fiction epic out of the 1930s, but according to space scientists, such a barrier already exists. Discovered by a pair of NASA space probes, the natural shield protects the Earth and near-Earth satellites from so-called "killer electrons" with a precision that cuts it off like a wall of glass.  Read More

The Stanford material cools buildings by both reflecting sunlight and radiating interior h...

Keeping buildings cool isn't easy. In fact, conventional air conditioning methods are very energy intensive and account for up to 15 percent of the energy used in buildings in the United States alone. However, engineers at Stanford University have come up with a new ultrathin, multilayered, nanophotonic material that not only reflects heat away from buildings, but also directs heat from inside out into space, cooling both the building and the planet as well.  Read More

Intrinsic Use Control uses the weapon’s fluctuating radiation fields to create use control...

Nuclear weapons are a paradox. No one in their right mind wants to use one, but if they're to act as a deterrent, they need to be accessible. The trick is to make sure that access is only available to those with the proper authority. To prevent a real life General Jack D Ripper from starting World War III, Livermore National Laboratory’s (LLNL) Defense Technologies Division is developing a system that uses a nuclear weapon's own radiation to protect itself from tampering.  Read More

MINER is a portable neutron scatter camera

It’s been a common trope in films since the 1950s; a madman with an atomic bomb holds a city for ransom while the authorities race to find it in time. If such a thing ever does come about, Sandia National Laboratories is working on taking the suspense out of the situation with its Mobile Imager of Neutrons for Emergency Responders (MINER) – a nuclear device detector capable of narrowing a search to within a city block without door-to-door sweeps.  Read More
