How bees naturally vaccinate their babies

When it comes to vaccinating their babies, bees don’t have a choice — they naturally immunize their offspring against specific diseases found in their environments. Now for the first time, scientists have discovered how they do it. This opens the door for researchers to develop the first-ever vaccine for insects. This is particularly important for bees since they help keep fruit, nuts and vegetables in our diets and have been declining in numbers for six decades.

Crystal clear images uncover secrets of hormone receptors

NIH scientists used atomic level images to show how the neuropeptide hormone neurotensin might activate its receptors. Their description is the first of its kind for a neuropeptide-binding G protein-coupled receptor, a class of receptors involved in a wide range of disorders and the target of many drugs.

Shaping the hilly landscapes of a semi-conductor nanoworld

Nanoscale worlds sometimes resemble macroscale roller-coaster style hills, placed at the tip of a series of hexagons. Surprisingly, these nanohills stem from the self-organisation of particles — the very particles that have been eroded and subsequently redeposited following the bombardment of semi-conductors with ion beams. Now, a new theoretical study constitutes the first exhaustive investigation of the redeposition effect on the evolution of the roughening and smoothing of two-dimensional surfaces bombarded by multiple ions. The study is published in EPJ B.

Tool helps public health agencies prioritize health risks

Public health agencies across the globe are challenged with preventing the spread of chronic diseases while dealing with limited funds and devastating budget cuts. Now, a researcher at the University of Missouri has applied the Public Health Index model, a tool he designed that has been adopted by the Missouri Department of Health and Senior Services, to help the Brazilian government identify and prioritize health risks affecting its population.

Findings in research on photoaging could reverse negative impact of ultraviolet radiation

Photoaging is a process that occurs when human skin is exposed to UV radiation from the sun that causes it to age at a faster rate than it would under normal circumstances. Though the process is known to occur how it works is not fully understood. InSilico Medicine’s GeroscopeTM software provided insights into this process that could help to combat it. The research will be presented at Basel Life Science Week 2015.

Gout medications might be useful in treating alcohol-induced liver disease

New research in mice shows that two commonly used gout medications, which target uric acid and adenosine triphosphate, may offer protection from alcohol-induced liver disease and inflammation. These findings suggest that clinical trials in humans with alcoholic liver disease should be considered. The report appears in the August 2015 issue of the Journal of Leukocyte Biology.

NICU admissions increasing for normal birth weight and term infants, Dartmouth study finds

Neonatal intensive care units were originally created for newborns who are extremely ill and/or underweight, but a Dartmouth study finds that NICU admission rates are increasing for newborns of all weights. In effect, NICUs are increasingly caring for normal, or near normal, birth weight and term infants.

Gold-diamond nanodevice for hyperlocalized cancer therapy

Precise targeting biological molecules, such as cancer cells, for treatment is a challenge, due to their sheer size. Now, Taiwanese scientists have proposed an advanced solution which can potentially be applied to thermal cancer therapy. An improved sensing technique for nanometer-scale heating and temperature sensing has been published in EPJ QT. Using a chemical method to attach gold nanorods to the surface of a diamond nanocrystal, the authors have invented a new biocompatible nanodevice.

Cheers! ‘Blue Moon’ Beer Celebrates Lunar Sight for 20th Anniversary

Cheers! 'Blue Moon' Beer Celebrates Lunar Sight for 20th AnniversaryIn a coincidence of cosmic proportions, the second full moon of July rises tonight, making it a so-called "Blue Moon" — and Blue Moon Brewing Co. will celebrate its 20th anniversary by painting the town red. A celestial Blue Moon comes around roughly every 2.7 years. Tonight (July 31), a Blue Moon will rise on the same night as Blue Moon Brewing Co. celebrates its 20th anniversary with parties and events at more than 750 locations across the country.

1 in 5 Adult Americans Report Having a Disability

About one in eight adults say they have mobility limitations, such as difficulty walking or climbing stairs, making this the most common type of disability, according to the report. The South had the highest percentages of people with disabilities, according to the report. Although the report did not analyze the reasons for the disparity between states, the South tends to have higher rates of chronic diseases associated with disability, including heart disease and diabetes, than the rest of the country, the CDC said.

Blue Moon Full Moon Rises Tonight: What to Expect

Blue Moon Full Moon Rises Tonight: What to ExpectThere's a "Blue Moon" in the sky tonight — but that doesn't mean the lunar surface will turn indigo. Tonight's (July 31) moon will be a gorgeous sight, but it won't look different than any other full moon. The term Blue Moon has come to refer to the second full moon in a given month (since full moons come around about every 29 days, most months only contain one).

The pair encountered a large oil sheen and called the fire department to investigate. The Coast Guard is investigating this new oil slick off the Southern California coast about a dozen miles from where a broken pipeline spilled thousands of gallons of crude into the ocean in May. (Mike Eliason/ Santa Barbara County Fire Department via AP)LOS ANGELES (AP) — Coast Guard officials say it will likely be a couple more days before they can definitively say what caused a miles-long oil slick to materialize off the Santa Barbara County coast this week, but an expert said Thursday it was more than likely the result of ocean-floor seepage.

Earth’s ‘magnetic personality’ much older than previously thought

An artist's depiction of Earth's magnetic field deflecting high-energy protons from the sun four billion years agoBy Will Dunham WASHINGTON (Reuters) – Earth's magnetic field has been a life preserver, protecting against relentless solar winds, streams of charged particles rushing from the Sun, that otherwise could strip away the planet's atmosphere and water. "It would be a pretty barren planet without it," said University of Rochester geophysicist John Tarduno. Researchers on Thursday said evidence entombed in tiny crystals retrieved from the outback of western Australia indicates the magnetic field arose at least 4.2 billion years ago, much earlier than previously believed.

Saving rhinos in a lab

By Ben Gruber San Francisco, California – Matthew Markus, of biotech company Pembient, is holding up a rhinoceros horn worth thousands of dollars on the black market because a poacher had to risk his life to kill an endangered species to obtain it.  At least that is what Markus would have you believe. The truth is this horn wasn’t cut off a rhino in the African savannah, it was bioengineered in lab in San Francisco. Rhino horns are comprised primarily of keratin, a family of proteins that make up hair and nails.
