The 3D-printed vertebral body next to the original unprepared and erroneously labeled plas...

Access to rare fossils is limited, potentially putting a go-slow on their study, while sharing them around increases the risk of damaging them. Researchers at Berlin's Charité Campus Mitte have combined data from computed tomography (CT) scans with 3D printing technology to make it possible to print any number of accurate 3D reproductions of fossilized bones, without any adverse effect on the originals.  Read More

A group of researchers at NIST working with engineers from Colorado-based Scientech has developed a new approach to measuring laser power using a mirror and a scale. This method, which measures the force on the mirror driven by the radiation pressure of the laser light, presents a more rugged and more portable solution than current meters.  Read More

Might the new development help shield astronauts from cosmic radiation? (Image: Shuttersto...

Using data from the IceCube Neutrino Observatory at the South Pole, scientists have reported progress in understanding the longstanding mystery of how and where cosmic rays originate, in a development that might help us find ways to shield astronauts and electronics from cosmic radiation.  Read More

The MTM Special Ops RAD watch includes an integrated Geiger-Müller tube for measuring harm...

There are few things more embarrassing than being caught in an all-out thermonuclear war and realizing that you've forgotten your Geiger counter. To prevent this social faux pas, MTM has released its Special Ops RAD watch. Available in black or silver (gray has already sold out) titanium cases, the RAD watch includes an integrated Geiger-Müller tube for measuring exposure to harmful ionizing radiation.  Read More

The arm's 11 joints allow it to snake in between pipes to get a better view of the damaged...

The Tokyo Electric Power Company's decommissioned Fukushima Daiichi nuclear power station, damaged in the March 2011 earthquake and tsunami, is still under investigation. Progress has been slow due to lethal radiation preventing workers from accessing the site, and a lack of industrial robots ready to tackle the job. Now Honda and Japan's National Institute of Advanced Industrial Science and Technology (AIST) have unveiled a High-Access Survey robot that began work inside the reactor building last week.  Read More

Boron neutron capture therapy can kill tumors without harming healthy neighboring tissue

Shortly after the discovery of the neutron in 1932, some scientists recognized the potential of boron neutron capture therapy (BNCT) as a cancer treatment. But despite decades of research, the problem of finding a delivery agent that would more effectively target the tumor without harming surrounding tissue persisted. Researchers at the University of Missouri (MU) may finally have found a solution.  Read More

The nanoparticle with a core of the element actinium, surrounded by four layers of materia...

Gold nanoparticles have already shown promise in precisely highlighting brain tumors, “blowing up” individual diseased cells, and developing a lung cancer breath test. Now researchers have created gold nanoparticles that allow an alpha particle-emitting element to be directed to small cancer tumors. The researchers say the gold coating keeps the powerful radioactive particles in place at the cancer site so they do negligible damage to healthy organs and tissue.  Read More

Researchers have developed a simple blood test to determine a patient's exposure to ionizi...

Industrial and medical accidents have resulted in about 3,000 cases of acute radiation syndrome with over 100 deaths over the past 60 years. Far larger numbers are possible in the future from major reactor accidents or the use of dirty bombs. In the aftermath of a major incident, the radiation dosages of victims must be sorted out quickly, so that suitable treatment can begin as soon as possible. Medical researchers at the US Lawrence Berkeley National Laboratory have now developed a simple blood test to determine the exposure of a patient to ionizing radiation, that can be carried out in the field with a hand-held analyzer.  Read More

Future manned deep space missions would expose astronauts to levels of radiation that can ...

Psychiatrists involved with the early days of NASA’s space program were concerned astronauts might succumb to “space madness” as a result of experiencing prolonged periods of microgravity and claustrophobic isolation. While their fears turned out to be unfounded, a new study has found cause for concern for the mental faculties of astronauts on planned future deep space missions. The study shows that the levels of radiation an astronaut would be exposed to on a mission to Mars could cause cognitive problems and accelerate the onset of Alzheimer’s disease.  Read More

New technology could make moldy bread a much less common sight (Photo: Shutterstock)

Bread may be the staff of life, but it doesn't keep very well. Left to its own devices, a loaf will start to go moldy in a week – a fact that costs consumers and the food industry millions of dollars each year. Now, according to the BBC, a Texas-based company have developed a process that kills spores so that a loaf of bread can stay mold-free for up to 60 days.  Read More
