Controlled-release fertilizers are a widely used method of delivering nutrients to nursery container crops. Controlled release is just like it sounds, the fertilizers contain encapsulated solid mineral nutrients that dissolve slowly in water which are released over an extended period of time.

Controlled-release fertilizers (CRFs)
are quite popular, but growers and researchers want ways to decrease fertilizer and irrigation expenses and reduce the impact of nutrient leaching into the environment, so a new study compares CRF placement strategies.

Folk wisdom has long held that people are more likely to catch a cold in cool-weather or damp conditions but some recent claims have disputed that and found the virus transmits just as often regardless of temperature.  This has been latched onto by people who advocate less energy usage in order to minimize fossil fuel usage.

But the rhinovirus, the most frequent cause of the common cold, can reproduce itself more efficiently in the cooler temperatures found inside the nose than at core body temperature, according to a new study. That means cold is bad. 

Bowhead whales can live to be over 200 years and show little evidence of the age-related disease that are apparent in humans in our senior years.

There may soon by answers why, thanks to a complete bowhead whale genome and identify key differences compared to other mammals. Alterations in bowhead genes related to cell division, DNA repair, cancer, and aging may have helped increase its longevity and cancer resistance. 

How might you make a new Earth? Our Terran "test kitchen" has given us a detailed recipe, it just wasn't clear how transposable it was in other areas, the same way a recipe in Los Angeles might not work as well in Denver. Now, astronomers have found evidence that the recipe for Earth also applies to terrestrial exoplanets orbiting distant stars.

"Our solar system is not as unique as we might have thought," says lead author Courtney Dressing of the Harvard-Smithsonian Center for Astrophysics (CfA). "It looks like rocky exoplanets use the same basic ingredients."

Controlled-release fertilizers are a widely-used method of delivering nutrients to nursery container crops, because they contain encapsulated solid mineral nutrients that dissolve slowly in water, which are then released into substrates over an extended period of time.

Although the use of controlled-release fertilizers is a popular and widely-accepted practice, growers and researchers are always looking for ways to get the same results with decreased fertilizer and irrigation expenses - and less nutrient leaching into the environment. A new study contains recommendations for controlled-release fertilizer placement methods that can address these issues.

Cold and damp is bad, no matter what you may have heard recently about it making no difference. The common cold virus reproduces itself more efficiently in the cooler temperatures found inside the nose than at core body temperature, confirming the popular-yet-recently-contested notion that people are more likely to catch a cold in cool, damp conditions. 

Scientifically it is known that the rhinovirus, the  most frequent cause of the common cold, replicates more readily in the slightly cooler environment of the nasal cavity than in the warmer lungs but, the focus of prior studies has been on how body temperature influenced the virus as opposed to the immune system, said study senior author and Yale professor of immunobiology Akiko Iwasaki.
