Newly published research by investigators at the Johns Hopkins Children's Center and the Johns Hopkins Institute of Genetic Medicine reveals that a faulty genetic pathway already known for its role in some connective tissue disorders is also a potent player in many types of allergies. Scientists have long understood that allergies are the result of a complex interplay between environment and genes, but now, in what investigators believe is a scientific first, a single genetic pathway has been implicated in an array of allergic disorders.
The cosmic fireworks that characterize a starburst galaxy can abruptly fizzle out after only a relatively brief period of star formation, and astronomers want to know why.

Researchers have developed a new screening and tracking tool for diagnosing autism. The method holds promise as a method to introduce interventions.
If your local pond, lake, or watering hole is looking bright green this summer, chances are it has blue-green algae and it may be dangerous to you or your pets. A newly published study has used a novel approach to better understand why these algae form blooms and what makes them toxic.
Spotify. Pandora. iTunes. YouTube. We are constantly bombarded with a seemingly limitless amount of new music in our daily lives. But why do we keep coming back to that one song or album we couldn’t get enough of in college? New research from Washington University’s Olin Business School shows that although consumers say they prefer to listen to unfamiliar music, their choices actually belie that preference.
American workers who found themselves in part-time positions in the aftermath of the economic downturn still struggle to find full-time work and are much more likely to be living in poverty than their peers with full-time work, according to new research from the Carsey Institute at the University of New Hampshire.
Mass extinctions, like lotteries, result in a multitude of losers and a few lucky winners. This is the story of one of the winners, a small, shell-crushing predatory fish called Fouldenia, which first appears in the fossil record a mere 11 million years after an extinction that wiped out more than 90 percent of the planet's vertebrate species.
A new poll shows 82 percent of adults support banning smoking in cars when children under 13 are riding in the vehicle.
Painstaking new analysis of the genetic sequence of the X chromosome—long perceived as the “female” counterpart to the male-associated Y chromosome—reveals that large portions of the X have evolved to play a specialized role in sperm production.
Today at the European Physical Society meeting in Stockholm, the international T2K collaboration announced definitive observation of muon neutrino to electron neutrino transformation. In 2011, the collaboration announced the first indication of this process, a new type of neutrino oscillation, then; now with 3.5 times more data this transformation is firmly established. The probability that random statistical fluctuations alone would produce the observed excess of electron neutrinos is less than one in a trillion. Equivalently the new results exclude such possibility at 7.5 sigma level of significance. This T2K observation is the first of its kind in that an explicit appearance of a unique flavor of neutrino at a detection point is unequivocally observed from a different flavor of neutrino at its production point.
Contrary to current scientific understanding, it appears that our microbial companions play an important role in their hosts' evolution. A new study provides the first direct evidence that these microbes can contribute to the origin of new species by reducing the viability of hybrids produced between males and females of different species.
The sight of a snowfall can thrill children, but the first-ever snow line seen around a distant star gives astronomers an even greater thrill because of what it reveals about the formation of planets and our Solar System's history.
Astronomers using NASA's Hubble Space Telescope have determined the orbital motion of two distinct populations of stars in ancient globular star cluster 47 Tucanae, offering proof they formed at different times and providing a rare look back into the Milky Way galaxy's early days.
Male bats appear to be the sexy singers of the animal world: they have learned to vocalize in a specific way to attract females, but once they have their attention, they change their tune – literally. They then produce a more creative array of sounds to entertain and keep the females interested.
A new study co-authored by Boston University astronomers indicates that a bow shock (a dynamic boundary between sun’s heliosphere and the interstellar medium) is highly likely. These findings challenge recent predictions that no such bow shock would be encountered.
Rapid tooth replacement by sauropods, the largest dinosaurs in the fossil record, likely contributed to their evolutionary success, according to a research paper by Stony Brook University paleontologist Michael D’Emic, PhD, and colleagues. Published in PLOS ONE, the study also hypothesizes that differences in tooth replacement rates among the giant herbivores likely meant their diets varied, an important factor that allowed multiple species to share the same ecosystems for several million years.
Archaeologists tunneling beneath the main temple of the ancient Maya city of El Perú-Waka’ in Guatemala have discovered a stone monument with hieroglyphic text detailing the exploits of a little-known sixth-century princess whose progeny prevailed in a bloody struggle between two of the civilization’s most powerful royal dynasties.
A five-year study gives new hope to some of the world’s most endangered primates by establishing a roadmap to protect all 27 species in Tanzania – mainland Africa's most primate-diverse country.
UA researchers have discovered the fossilized remains of an elasmosaur. A subgroup of the late Cretaceous plesiosaurs, the elasmosaurid plesiosaurs are recognized by their large body size and shape. This find is only the second elasmosaurid specimen containing more than one or two bones found in Alabama.

Artificial and natural knowledge researchers at the University of Illinois at Chicago IQ-tested one of the best available artificial intelligence systems and learned that it’s about as smart as the average 4-year-old.
NASA's Hubble Space Telescope has discovered a new moon orbiting the distant blue-green planet Neptune, the 14th known to be circling the giant planet. The moon, designated S/2004 N 1, is estimated to be no more than 12 miles across, making it the smallest known moon in the Neptunian system.
A new report by the Wildlife Conservation Society (WCS) and the Disease Ecology Laboratory of Instituto de Ciencias Veterinarias del Litoral, Argentina (ICIVET LITORAL, UNL-CONICET) shows that increases in precipitation and changes in vegetative structure in Argentine forests – factors driven by climate change and deforestation in the region – are leading to increased parasitism of young nesting birds by fly larvae (botflies) of the species Philornis torquans.
Swarms of small earthquakes can precede a volcanic eruption, sometimes resulting in "harmonic tremor" resembling sound from some musical instruments. A new analysis shows tremor during a 2009 sequence at Alaska's Redoubt Volcano glided to substantially higher frequencies, then stopped abruptly just before six of the eruptions.
Scientists have created a virtual model of the brain that daydreams like humans do. They hope the model will help them understand why certain portions of the brain work together when a person is mentally idle.
When we think of our prehistoric ancestors, we don’t usually imagine them lining graves with flowers – yet Weizmann scientists have now identified the oldest such grave. Using the Institute’s new accelerator mass spectrometer, the team will not only uncover new information about prehistoric life, but also overturn some long-held theories.
Astronomers using NASA's Hubble Space Telescope have deduced the actual visible-light color of a planet orbiting another star 63 light-years away. If seen directly the planet, known as HD 189733b, would look like a "deep blue dot," reminiscent of Earth's color as seen from space.
Based on the analysis of 3-D landmark data from skull surfaces of Homo floresiensis, scientists provide compelling support for the hypothesis that Homo floresiensis was a distinct Homo species.
Older people with Alzheimer’s disease are less likely to also have cancer, and older people with cancer are less likely to also have Alzheimer’s disease, according to the largest study to date on the topic, which appears in the July 10, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Indiana University scientists have transformed mouse embryonic stem cells into key structures of the inner ear. The discovery provides new insights into the sensory organ's developmental process and sets the stage for laboratory models of disease, drug discovery and potential treatments for hearing loss and balance disorders.
Wind power development does not ruffle the feathers of greater prairie chicken populations, according to a seven-year study from a Kansas State University ecologist and his team. They found that grassland birds are more affected by rangeland management practices and by the availability of native prairie and vegetation cover at nest sites.
The most common thing that couples want from each other during a conflict is not an apology, but a willingness to relinquish power, according to a new Baylor University study.
The rates of regional brain loss and cognitive decline caused by aging and the early stages of Alzheimer’s disease (AD) are higher for women and for people with a key genetic risk factor for AD, say researchers at the University of California, San Diego School of Medicine in a study published online July 4 in the American Journal of Neuroradiology.

A normally staid University of Chicago scientist has stunned many of his colleagues with his radical solution to a 135-year-old mystery in cosmochemistry. At issue is how numerous small, glassy spherules had become embedded within specimens of the largest class of meteorites—the chondrites.
A female’s exposure to distress even before she conceives causes changes in the expression of a gene linked to the stress mechanism in the body — in the ovum and later in the brains of the offspring from when they are born, according to a new study on rats conducted by the University of Haifa.
A new study led by Florida State University researcher Stephanie Pau shows that tropical forests are producing more flowers in response to only slight increases in temperature.
You are what you eat – and so are your offspring. And in the title bout featuring protein versus sugar, protein is the winner. That’s what a researcher at The University of Alabama in Huntsville (UAH) found while studying the fruit fly (Drosophila melanogaster) as part of a multi-institutional team.
According to a study supervised by Ithaca College’s Exercise and Sport Sciences Chair Thomas Swensen, betaine—a nutrient found in shellfish and beets—boosts athletic performance by nearly six percent when added to a sports drink.
The modern custom of laying flowers in graves or using them for funerals dates back to as early as 13,700 years ago, to our Natufian ancestors living in Mt. Carmel. “Even back then, the Natufians had burial rituals much similar to ours, nowadays”, said Prof. Dani Nadel, from the University of Haifa, who led the excavations.
