Tomatoes may combat the damaging effects of radiation

A team of researchers from have discovered that lycopene – the red pigment in tomatoes – is extremely successful at guarding against the harmful effects of radiation.

Dr Ruth Edge from The University of Manchester, together with her colleagues Professor George Truscott from Keele University and Professors Fritz Boehm & Christian Witt from Berlin, undertook a study of lycopene (one of the carotenoids – plant pigments found in many fruits and vegetables) and its effectiveness at protecting against radiation at the University of Manchester’s Dalton Cumbrian Facility, part of the Dalton Nuclear Institute.

Scientists Find Leukemia’s Surroundings Key to its Growth

AUSTIN, Texas — Researchers at The University of Texas at Austin have discovered that a type of cancer found primarily in children can grow only when signaled to do so by other nearby cells that are noncancerous. The finding, published in the Proceedings of the National Academy of Sciences, contributes to a growing body of research that implicates the environment around a cancer in its spread — an area of study that holds promise for new alternatives to treat the disease.

A new way to make laser-like beams using 250x less power

ANN ARBOR — With precarious particles called polaritons that straddle the worlds of light and matter, University of Michigan researchers have demonstrated a new, practical and potentially more efficient way to make a coherent laser-like beam.

They have made what’s believed to be the first polariton laser that is fueled by electrical current as opposed to light, and also works at room temperature, rather than way below zero. (more…)

How Yale doctors are making CT scans safer for kids

Greater awareness and careful usage are bringing down the numbers of pediatric CT scans and cutting radiation exposure. Parents should weigh the benefits and risks.

(September 2013) If your child had a CT scan last year—perhaps to assess damage from a hockey injury or rule out appendicitis—he or she added to a huge statistic: more than 4 million pediatric CT scans were performed in the U.S in 2012.

The experience can leave you a little anxious, since the radiation from a CT scan may increase the risk of cancer, especially in children.

Fortunately, that picture may be changing, especially for children, who are even more susceptible to radiation-induced cancer than adults. In data compiled by the American College of Radiology’s Dose Index Registry, which tracks and categorizes the radiation given by CT scanners in U.S. hospitals, Yale-New Haven Children’s Hospital (YNHCH) recorded the lowest doses of any academic hospital in the country in many age groups and types of pediatric radiation.

In the Zone: How Scientists Search for Habitable Planets

There is only one planet we know of, so far, that is drenched with life. That planet is Earth, as you may have guessed, and it has all the right conditions for critters to thrive on its surface. Do other planets beyond our solar system, called exoplanets, also host life forms?

Astronomers still don’t know the answer, but they search for potentially habitable planets using a handful of criteria. Ideally, they want to find planets just like Earth, since we know without a doubt that life took root here. The hunt is on for planets about the size of Earth that orbit at just the right distance from their star – in a region termed the habitable zone. (more…)

Listening to the Big Bang – in high fidelity

A decade ago, spurred by a question for a fifth-grade science project, University of Washington physicist John Cramer devised an audio recreation of the Big Bang that started our universe nearly 14 billion years ago.

Now, armed with more sophisticated data from a satellite mission observing the cosmic microwave background – a faint glow in the universe that acts as sort of a fossilized fingerprint of the Big Bang – Cramer has produced new recordings that fill in higher frequencies to create a fuller and richer sound. (The sound files run from 20 seconds to a little longer than 8 minutes.) (more…)

CU study provides new evidence ancient asteroid caused global firestorm on Earth

A new look at conditions after a Manhattan-sized asteroid slammed into a region of Mexico in the dinosaur days indicates the event could have triggered a global firestorm that would have burned every twig, bush and tree on Earth and led to the extinction of 80 percent of all Earth’s species, says a new University of Colorado Boulder study.

Led by Douglas Robertson of the Cooperative Institute for Research in Environmental Sciences, or CIRES, the team used models that show the collision would have vaporized huge amounts of rock that were then blown high above Earth’s atmosphere. The re-entering ejected material would have heated the upper atmosphere enough to glow red for several hours at roughly 2,700 degrees Fahrenheit — about the temperature of an oven broiler element — killing every living thing not sheltered underground or underwater.

Using a video game system to get exercise at home can help patients overcome one of cancer’s most common and cumbersome symptoms: severe, persistent fatigue.

Michigan State University’s Amy Hoffman and colleagues showed in an earlier study that the Nintendo Wii system was a safe and effective source of light-intensity exercise for patients with non-small cell lung cancer in the first six weeks after surgery. (more…)
