Neutrinos can zip right through your body, the walls of your house, entire planets, even emerging from near the surface of fascinating and frightening black holes. And now, an international scientific collaboration that includes researchers from the University of Delaware has taken an 'astronomical' step forward in unmasking the origins of some of these high-energy particles, the so-called “messengers of the universe.”
Astronomers using the combined power of the Atacama Large Millimeter/submillimeter Array (ALMA) telescope and NASA’s Hubble Space Telescope have discovered a far-flung trio of primitive galaxies nestled inside an enormous blob of primordial gas nearly 13 billion light-years from Earth.
New research from the Icahn School of Medicine at Mount Sinai reveals long-term cocaine abuse may be associated with deficits in parts of the brain involved in monitoring and overseeing one’s own behavior.
A new study by scientists from Nova Southeastern University’s (NSU) Save Our Seas Shark Research Centre and Cornell University published in final form today in the journal BMC Genomics now undertakes the first large-scale exploration of the great white shark’s genetic repertoire, and comes up with unexpected findings.
Results from a DNA study of a young boy’s skeletal remains believed to be 24,000 years old could turn the archaeological world upside down – it’s been proven that nearly 30 percent of modern Native American’s ancestry came from this youngster’s gene pool, suggesting First Americans came directly from Siberia.
Obese people who are currently metabolically healthy face a higher risk of developing diabetes and cardiovascular disease, according to new research accepted for publication in The Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.
The “social safety net” expanded to catch many Americans during the economic downturn and welfare programs "did their job and made a difference," an economist has found.
Grammar and syntax have been thought for decades to be automatic and untouchable by other brain processes and that everything else — the sex of the speaker, their dialect, etc. — is stripped away as our brains process the sound signal of a word and store it as an abstract form. A University of Kansas study suggests that even higher-level processes – in this case – grammar - are affected by information about the speaker.
Liberals tend to underestimate the amount of actual agreement among those who share their ideology, while conservatives tend to overestimate intra-group agreement, researchers in NYU’s Department of Psychology have found.
Unexpected behavior in ferroelectric materials explored by researchers at the Department of Energy’s Oak Ridge National Laboratory supports a new approach to information storage and processing.
Annual rates of CPR training in the United States are low and vary widely across the country, but the communities most in need of training are the least likely to be trained, according to a new study from the Duke Clinical Research Institute.
University of Utah biologists found that when mother mice compete socially for mates in a promiscuous environment, their sons play hard and die young: They attract more females by making more urinary pheromones, but smelling sexier shortens their lives.
Why are men's noses bigger than women's? The answer, according to a new study from the University of Iowa, lies in our physiology. Men's noses are about 10 percent larger than female noses, on average, because males have more lean muscle mass, which requires more oxygen for muscle tissue growth and maintenance. It also explains why we have smaller noses than our ancestors. Results appear in the American Journal of Physical Anthropology.
A temporary seismic array in Marie Byrd Land in West Antarctica recorded two bursts of activity in 2010 and 2011. Careful analysis of the events shows they originate from a subglacial volcano at the leading end of a volcanic mountain chain. The volcano is unlikely to erupt through the kilometer of ice that covers it but it will melt enough ice to change the way the ice in its vicinity flows.
Diseases affecting the kidneys represent a major and unsolved health issue worldwide. The kidneys rarely recover function once they are damaged by disease, highlighting the urgent need for better knowledge of kidney development and physiology.
Researchers now have stronger evidence of granite on Mars and a new theory for how the granite – an igneous rock common on Earth -- could have formed there, according to a new study. The findings suggest a much more geologically complex Mars than previously believed.
Research in recent years has suggested that young Americans might be less creative now than in decades past, even while their intelligence — as measured by IQ tests — continues to rise. But new research from the University of Washington Information School and Harvard University, closely studying 20 years of student creative writing and visual artworks, hints that the dynamics of creativity may not break down as simply as that. Instead, it may be that some aspects of creativity — such as those employed in visual arts — are gently rising over the years, while other aspects, such as the nuances of creative writing, could be declining.
Scientists have developed a new computer modeling technique that offers the promise, for the first time, of producing continually updated daylong predictions of wildfire growth throughout the lifetime of long-lived blazes. The technique, developed by a research team led by NCAR, combines detailed computer simulations with newly available satellite observations.
Astronomers studying gas halos around nearby galaxies were surprised when detailed studies with the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) showed that one of their subjects is not a single galaxy, but rather two, nearly perfectly superimposed on the sky to masquerade as one.
NASA's Hubble Space Telescope has provided the first visual evidence showing how our home galaxy, the Milky Way, assembled itself into the majestic pinwheel of stars we see today. Perusing Hubble's deep-sky surveys, astronomers traced 400 galaxies similar to our Milky Way at various stages of construction over a time span of 11 billion years.

A pair of carbon nanotube arrays will be flying in space by the end of the year to test technology that could provide more efficient micro-propulsion for future spacecraft. The arrays will support what is expected to be the first-ever space-based testing of carbon nanotubes as electron emitters.
Friendly microbes in the intestinal tracts of healthy American children have numerous antibiotic resistance genes that could be passed to harmful microbes, according to a pilot study by scientists at Washington University School of Medicine in St. Louis.
The deletion of any single gene in yeast cells puts pressure on the organism’s genome to compensate, leading to a mutation in another gene. The discovery is likely applicable to human genetics and cancer, and could have significant consequences for the way genetic research is done.
It’s not every day that fishermen catch the world’s largest fish species in their nets, but this is what recently happened in Indonesia’s Karimunjawa National Park, according to the Wildlife Conservation Society.
A study by an international team of researchers will help decrease the risk of dengue, a life-threatening mosquito-borne viral disease that is now one of the fastest spreading tropical diseases globally.
Researchers at the Cardiovascular Research Center at Icahn School of Medicine at Mount Sinai have successfully tested a powerful gene therapy, delivered directly into the heart, to reverse heart failure in large animal models.
A natural shift to stronger warm El Niño events in the Pacific Ocean might be responsible for a substantial portion of the global warming recorded during the past 50 years, according to new research at The University of Alabama in Huntsville (UAH).
UCLA researchers report that tiny amounts of a specific type of lipid in the small intestine may play a greater role than previously thought in generating the high cholesterol levels and inflammation that lead to clogged arteries. The team also found they could reduce the negative effects of these lipids in mice by feeding the animals a new genetically engineered tomato being developed at UCLA that is designed to mimic HDL (“good”) cholesterol. The study, in the December issue of the Journal of Lipid Research with an accompanying editorial, focused on a group of lipids found in the small intestine called unsaturated lysophosphatidic acids (LPAs).
If there is a reasonable chance of increasing wealth in the parents’ environment then no difference is made between one’s own children and stepchildren.
Tiny electrical wires protrude from some bacteria and contribute to rock and dirt formation. Researchers studying the protein that makes up one such wire have determined the protein's structure. The finding is important to such diverse fields as producing energy, recycling Earth's carbon and miniaturizing computers.
Invisibility cloaking is no longer the stuff of science fiction: two researchers in The Edward S. Rogers Sr. Department of Electrical & Computer Engineering have demonstrated an effective invisibility cloak that is thin, scalable and adaptive to different types and sizes of objects.
A specialized type of brain cell that tamps down stem cell activity ironically, perhaps, encourages the survival of the stem cells’ progeny, Johns Hopkins researchers report. Understanding how these new brain cells “decide” whether to live or die and how to behave is of special interest because changes in their activity are linked to neurodegenerative diseases such as Alzheimer’s, mental illness and aging.
Some vegetable oils that claim to be healthy may actually increase the risk of heart disease, and Health Canada should reconsider cholesterol-lowering claims on food labelling, states an analysis in CMAJ (Canadian Medical Association Journal) http://www.cmaj.ca/lookup/doi/10.1503/cmaj.130253.

The combination of the two technologies could be an important step toward the development of useful, practical telemedicine.
Ocean conditions like current directions and water temperature play a huge role in determining the behavior of young migrating salmon as they move from rivers and hit ocean waters for the first time. How the fish fare during their first few weeks in the ocean has a profound impact on their ability to survive.
UT Southwestern Medical Center researchers report that disrupting the light-dark cycle of mice increased their susceptibility to inflammatory disease, indicating that the production of a key immune cell is controlled by the body’s circadian clock.
A Columbia-led research team has clinically validated a new method for predicting time to nursing home residence or death for patients with Alzheimer’s. The method uses data from a single patient visit, and is based on a complex model of Alzheimer’s progression developed by consecutively following two sets of Alzheimer’s patients for 10 years each.
Although we don’t often think about it, fluid dynamics touches almost every aspect of our lives, from a billowing breeze that buffets a flag, to swirling river currents that shape canyons to the surging blood that sustains our lives. One of the basest of bodily functions -- urination -- is governed primarily by the equations of fluid motion.
Two groups of scientists at the Children’s Medical Center Research Institute at UT Southwestern (CRI) have made complementary discoveries that break new ground on efforts to turn back the body’s clock on cellular activity, paving the way for a better understanding of stem cells, tissue growth, and regeneration.
Researchers at Washington University School of Medicine in St. Louis have identified a chain reaction that triggers the regrowth of some damaged nerve cell branches, a discovery that one day may help improve treatments for nerve injuries that can cause loss of sensation or paralysis.
Hubble researchers say they were "literally dumbfounded" when they took a close-up look at P/2013 P5, an object that lives in the asteroid belt but superficially looks like a comet. It has no less than six dust tails that seem to be forming sequentially. The entire structure rotates like a bicycle wheel with spokes on one side.
Red Panda Cubs Debut at Bronx Zoo and Prospect Park Zoo
More people are cooking at home, and more people are finding their recipes online via food blogs. The photos of dishes posted on the blogs, however, may attract potential cooks more than the nutritional value of the recipes. In addition, many food companies sponsor these sites, so the recipes become advertisements for their products. This has the potential to change the healthfulness of the recipes.
