For decades, researchers have been making artificial eggs out of plaster, wood, and other materials to test how birds identify and reject the eggs that invading 'brood parasites' sometimes sneak into their nests. But these methods have many limitations; a new study is the first to test the usefulness of 3-D printed eggs for research on egg rejection.
The laurel wilt pathogen can severely damage Florida's avocado crop, which provides a $100 million-a-year economic impact on Florida. But the new camera images can give growers a jump-start on the disease.
MicroRNA can serve as a “decoder ring” for understanding complex biological processes, a team of chemists has found. Their study points to a new method for decrypting the biological functions of enzymes and identifying those that drive diseases.
Air pollution regulations issued by the U.S. Environmental Protection Agency are estimated to save thousands of lives annually. A new study, however, says these estimates are more uncertain than commonly believed.
Being very overweight in your teens may double the risk of developing bowel cancer by the time you are middle aged, suggests new research.
The form of estrogens used in Hormone Therapy (HT) and previous motherhood are critical to explain why HT has variable effects on cognitive functions, new research suggests. In a recent study, estradiol had beneficial effects while estrone did not, researchers explain, adding that the effects of estrone also depended on the experience of motherhood.
The World Health Organization's current weight-based guidelines for assessing malnutrition in children with diarrhea are not as reliable as measuring the child's upper arm circumference, new research suggests.
Sperm in the first fraction of ejaculate are more numerous, move more and present better quality DNA than those lagging behind. This is the conclusion of a study that confirms that while the objective of the first fraction is to fertilize the egg, the second phase is so that no sperm from any other male has a chance to fertilize it.
Giant strides have been taken in the early care of very premature infants in postnatal intensive care units during the past two decades. Doctors can now support the function of especially the lungs, heart and the circulatory system so...Show More Summary
Mitsuyoshi Nakao, Director of the Institute of Molecular Embryology and Genetics in Kumamoto University and Associate Professor Noriko Saitoh revealed that a cluster of defined, non-coding RNAs are mechanistically involved in endocrine therapy resistance in human breast cancer cells.

RNA extraction is a notoriously tricky and sensitive lab procedure, but new protocols are quicker, more effective, and more reliable than previous methods. The protocols are featured in bench-ready form with detailed notes and a troubleshooting guide tested extensively on a diverse selection of woody, aromatic, and aquatic plants.
Cough treatments could change dramatically after the herpes virus helped researchers discover that the respiratory tract links to two different parts of the nervous system.
Glancing at a grassy green roof for only 40 seconds markedly boosts concentration, a new study concludes. The green roof provided a restorative experience that boosted those mental resources that control attention, researchers say.
Two new classes of RNAs have been identified that are closely associated with a protein known to be a prognostic biomarker for breast cancer and could play a role in progression of prostate cancer.
If you’re watching television while using a second screen – like a smartphone or tablet – new research suggests that some of the most expensive marketing messages aimed at you are missing their mark.
New technology makes cell phone batteries last up to 30 percent longer on a single charge. The patented circuitry converts some of the radio signals emanating from a phone into direct current (DC) power, which then charges the phone's battery.
A global-scale study has estimated how forest emitted compounds affecting cloud seeds via formation of low-volatility vapours. According to the latest projections, terrestrial vegetation emits several million tons of extremely low-volatility organic compounds (ELVOCs) per year to the atmosphere. read more
The world's smallest dolphin, found only off the coast of New Zealand, could disappear within 15 years unless efforts are taken to bring the critically endangered animal back from the brink of extinction. In what they deem a "loud wake-up call," researchers at German conservation group NABU say 43 to...
The search for habitable planets currently focuses on so-called M dwarfs - stars with less than half the mass of the Sun. These stars are thought to have more habitable orbiting planets that are easier to find compared with G...
A 10 th -grader perches on the edge of her chair as her biology teacher lectures on evolution. She listens intently. The years she’s spent in Sunday school and church services have prepared her for this very moment. Her hand shoots up, and the teacher calls her name. Show More Summary
