This is the first high-energy X-ray analysis of plant-microbe interactions. X-rays such as those from the APS provided a high sensitivity to elements and a high spatial resolution not attainable by other means.
All of the rats were fed berries 2 months prior to radiation and then divided into two groups-one was evaluated after 36 hours of radiation and the other after 30 days.
After 30 days on the same berry diet the rats experienced significant protection against radiation compared to control said investigator Shibu Poulose Phd.
We saw significant benefits to diets with both of the berries and speculate it is due to the phytonutrients present.

#Toxicity map of brain may help protect cognition for cancer patientsnew research from Wake Forest Baptist Medical center is giving radiation oncologists who treat brain tumors a better understanding of how to preserve the brain's functions while still killing cancer.
Ann M. Peiffer Ph d. assistant professor of radiation oncology at Wake Forest Baptist and colleagues looked at how radiation treatment to different brain areas impacts function to help protect cognition
Radiation treatment of organs with cancer is designed to give enough of a dose to be toxic to the cancer tumor with minimal impact to the surrounding tissue
For treatment of organs like the lung kidney or liver doctors know exactly how much radiation to give before organ function is affected.
and these functions are affected at a much lower dose of radiation than what causes tissue death Peiffer said.
or more after their radiation treatment to determine whether Donepezil a drug normally used to improve mental function for those with early Alzheimer's disease was effective at improving their cognition.
The researchers then went back into the medical records to match participants to their individual radiation dose levels
This gave us a preliminary look at what areas are important to consider for protecting cognition during our planning for radiation treatment.
Individuals were supported also by Wake Forest School of medicine Medical student Research Program Louis Argenta Physician-Scientist Scholarship Fund NIH T32 CA113267 and the Department of Radiation Oncology.
SIT involves mass release of radiation-sterilized insects which mate but produce no offspring thus reducing the population of pests.
They include difficulty in producing male-only sterile insects without the use of radiation which reduces their ability to compete with wild males for mates.

#Smaller radiation fields can spare brain when treating tumors, research findsnew research from Wake Forest Baptist Medical center shows that patients suffering from aggressive brain tumors can be treated effectively with smaller radiation fields to spare the rest of the brain and preserve cognition.
For patients with glioblastoma we now know we can safely and effectively treat them with smaller radiation fields to spare the rest of their normal brain said lead investigator Michael D. Chan M d. assistant professor of radiation oncology at Wake Forest Baptist.
That's important because it lessens the symptoms from radiation toxicity like tiredness and nausea.
Chan said that a patient's cognition is related to how much normal brain is irradiated so focusing radiation on smaller areas of the brain may help preserve cognition
and does not seem to lead to an increase in the likelihood of the tumor recurring.
Overall while long-term survival rates for glioblastoma multiforme patients have not improved by much with treatment advances the ability to treat with smaller radiation fields preserves cognition
While there have been other similar studies this one is the largest to compare smaller radiation margins to larger ones to document differences in patterns of failure for patients Chan said.
whether using these tighter margins would affect the tumors coming back outside of the radiation field
Chan said that in the 1990s Wake Forest Baptist's Edward G. Shaw M d. professor of radiation oncology was part of a group that pioneered using smaller margins
Smaller radiation margins around the tumor do not seem to lead to an increase in the tumor returning just outside of the radiation field Chan said.
A smaller radiation field combined with modern treatment techniques like newer chemotherapy agents and radiation technologies provides physicians with more options.
Treatments have gotten better over time and people with GBM may live longer than they had in the past.

The albedo effect refers to the amount of radiation reflected by the surface of the planet.
Not just the intensity but also the waveform of emitted terahertz radiation totally and dynamically changes in response to molecular adsorption and desorption.
Laser pulses generated coherent bursts of terahertz radiation through a built-in surface electric field of the indium phosphide substrate that changed due to charge transfer between the graphene and the contaminating molecules.
Using this method means that the males do not have to be sterilized by radiation before release
Researchers have observed long hemagglutinin's initial and final structures through X-ray crystallography. But because the change happens so quickly it has been impossible to capture an image of the glycoprotein in transit.
By using the experimental structural information from X-ray crystallography to approximate the full energy landscape of hemagglutinin the researchers can now capture a rough picture of the steps involved in its reconfiguration including the point at
and net radiation--defined as the amount of energy from the sun that is absorbed by the land minus the amount reflected back into the atmosphere by Earth's surface.
and found that a downward trend in net radiation was largely responsible for the change. This was a surprising result according to Estes who said he expected to see decreases in evaporative demand
but thought lower wind speeds would have a greater impact than drops in net radiation.
Aerosols reflect radiation from the sun back into space; this tends to cool Earth's surface. Aerosols such as dust and smoke also absorb radiation
and heat the atmosphere where they are concentrated. Aura's Ozone Monitoring Instrument (OMI) is especially good at observing these absorbing aerosols above clouds and bright deserts.
In addition the X-ray images show that both creatures died from suffocation after inhaling mud. Lyuba and Khroma who died at ages 1 and 2 months respectively are the most complete and best-preserved baby mammoth specimens ever found.

#Radiation damage at the root of Chernobyls ecosystemsradiological damage to microbes near the site of the Chernobyl disaster has slowed the decomposition of fallen leaves
They set out to assess the rate at which plant material decomposed as a function of background radiation placing hundreds of samples of uncontaminated leaf litter (pine needles and oak maple and birch leaves) in mesh bags throughout the area.
The locations were chosen to cover a range of radiation doses and the samples were retrieved after nine months outdoors.
A statistical analysis of the weight loss of each leaf litter sample after those nine months showed that higher background radiation was associated with less weight loss.
The response was proportional to radiation dose and in the most contaminated regions the leaf loss was 40 percent less than in control regions in Ukraine with normal background radiation levels.
They also measured the thickness of the forest floor in the same areas where samples were placed.
They found that it was thicker in places with higher background radiation. The team concluded that the bacteria
which he says likely results both from direct radiation effects and indirect effects such as reduced nutrient supply.
Structural techniques like X-ray crystallography and nuclear magnetic resonance have worked quite well to help us understand how smaller proteins function Onuchic said.
But blasting these secret-suitor insects with radiation via electron beams X-rays or gamma-rays tends to make them weaker than typical males
They suspected and found that under the low-oxygen conditions the insects'cells would produce antioxidants that can help better protect them from the off-target radiation damage.

The research team investigated adaptive radiation--the explosive evolution of species into new ecological niches powered by natural selection--of New world Leaf-nosed bats.
This kind of engineering model may illuminate many other adaptive radiations and the origin of so much diversity On earth.
valos of Stony Brook University and support from the National Science Foundation studied the evolutionary histories of the adaptive radiation of New world leaf-nosed bats based on their dietary niches.
As the authors point out adaptive radiations that is the explosive evolution of species into new ecological niches have generated much of the biological diversity seen in the world today.
radiation which transfers thermal energy through electromagnetic waves and conduction which transfers thermal energy through the vibrations of neighboring atoms and molecules.
But she and her colleagues suspected that radiation might play a bigger role. The scientists performed some initial calculations that showed heat loss between two bodies separated by air would be dominated by radiation not conduction.
To further explore the radiative heat loss the team created a simple computer model consisting of a hot and a cold thermostat that roughly simulated an animal's warm body and the outside colder environment.
which absorb all of the radiation that strikes them. In a second version opaque grey-body shields were used.

The government hid information about radiation levels after the Fukushima meltdown and for the first time, people are really angry,
They were also really angry that the Japanese government covered up the fact that they knew how high radiation levels were in places like Tokyo.
but they may have exposed themselves to more radiation than they thought. How people find reliable information A lot of people have become skeptical of NHK, the big television network in Japan.
Low levels of radiation spread to such a wide area throughout Japan. In some places, they have scraped off the top layer of playgrounds and schools,
Radiation levels were said to be high in the area so people were advised to stay inside for weeks.
In June, people were still jittery about radiation exposure. They banned some produce and milk from Ibaraki Prefecture where my parents live.

and Chernobyl for instance-they do not emit radiation to the general public. It's all contained.
The average coal plant has spewed far more radiation over the years than has nuclear. Coal operators are allowed to do this under naturally occurring radioactive materials (NORM) exemptions.
Hargraves reminds us that in our daily lives we encounter constant natural background radiation from sources like cosmic rays, breathing radon, ingestion of food and water,
