The ability to learn complex, symbolic math is a uniquely human trait, but it is intricately connected to a primitive sense of magnitude that is shared by many animals, finds a new study.

Researchers have learned how a human-made molecule destroys complexes that induce allergic responses -- a discovery that could lead to the development of highly potent, rapidly acting interventions for a host of acute allergic reactions.
Researchers have identified several genes that are linked to one of the most lethal forms of uterine cancer, serous endometrial cancer. The researchers describe how three of the genes found in the study are frequently altered in the disease, suggesting that the genes drive the development of...
Scientists have identified grid cells, neurons that fire in repeating triangular patterns as the eyes explore visual scenes, in the brains of rhesus monkeys. This is the first time grid cells have been detected directly in primates. The finding has implications for understanding how humans form and remember mental maps of the world, as well as how neurodegenerative diseases such as Alzheimer's...
Scientists have developed a prototype ultra-sensitive sensor that would enable doctors to detect the early stages of diseases and viruses with the naked eye.
With greenhouse warming, rainfall in the South Pacific islands will depend on two competing effects -- an increase due to overall warming and a decrease due to changes in atmospheric water transport -- according to a new study. In the South Pacific these two effects sometimes cancel each other out, resulting in highly uncertain rainfall...
Amyotrophic lateral sclerosis, also called Lou Gehrig's disease, is a devastatingly cruel neurodegenerative disorder that robs sufferers of the ability to move, speak and, finally, breathe. Now researchers have used baker's yeast -- a tiny, one-celled organism -- to identify a chink in the armor of the currently incurable disease that may eventually lead to new therapies for human...
Doxorubicin, a 50-year-old chemotherapy drug still in widespread use against a variety of cancers, has long been known to destroy heart tissue, as well as tumors, in some patients. Scientists have now identified an unexpected mechanism via the enzyme Top2b that drives the drug's attack on heart muscle, providing a new approach for identifying patients who can safely tolerate doxorubicin and for...
Physicists have proposed an experiment that could force us to make a choice between extremes to describe the behaviour of the Universe.
Due to the exponential increase in sequencing capacity, efficient tools for data analysis are becoming essential to process the vast amount of biological data. Scientists have now developed a tool for the interpretation of genomic data that is several times faster and much more accurate than other tools currently being...
A protein called resistin, secreted by fat tissue, causes high levels of "bad" cholesterol, increasing the risk of heart disease.
Men whose testosterone drops following radiation therapy for prostate cancer are more likely to experience a change in PSA levels that signals their cancer has returned, according to new research.
The influenza vaccine could be an important treatment for maintaining heart health and warding off cardiovascular events like strokes and heart attacks.
Routine electrocardiogram results for patients with atrial fibrillation can help doctors identify those at higher risk of adverse cardiovascular outcomes, including death.
Scientists have discovered how modifying a gene halts the toxic buildup of a protein found in nerve cells. These findings point to a potential new tactic for treating a variety of neurodegenerative conditions, including amyotrophic lateral sclerosis.
For the first time, researchers have provided a direct comparison of gene expression profiles from African-American and East African breast tissue samples, according to new results.
Hurricane Sandy is a Category 1 hurricane on Oct. 28, according to the National Hurricane Center. Sandy has drawn energy from a cold front to become a huge storm covering a large area of the eastern United States. NASA satellite imagery provided a look at Sandy's 2,000-mile...
A Space Exploration Technologies (SpaceX) Dragon spacecraft splashed down in the Pacific Ocean at 2:22 p.m. CDT Sunday a few hundred miles west of Baja California, Mexico. The splashdown successfully ended the first contracted cargo delivery flight contracted by NASA to resupply the International Space...
They say that necessity is the mother of invention, so when humans decided to build and inhabit a laboratory in the harsh environment of space, it was only natural that innovations would follow. The creators of these developments sought patents to protect their intellectual property, giving a way to gauge microgravity advancements. A recently published paper looks back at the more than 818 patents...

Nearly three quarters of the coast along the Delmarva Peninsula is very likely to experience beach and dune erosion as Hurricane Sandy makes landfall, while overwash is expected along nearly half of the shoreline.
Storm response crews from the U.S. Geological Survey are installing more than 150 storm-tide sensors at key locations along the Atlantic Coast -- from the Chesapeake Bay to Massachusetts -- in advance of the arrival of Tropical Storm Sandy.
The NASA/ESA Hubble Space Telescope has imaged the faint irregular galaxy NGC 3738, a starburst galaxy. The galaxy is in the midst of a violent episode of star formation, during which it is converting reservoirs of hydrogen gas located in the galaxy's center into stars. Hubble spots this gas glowing red around NGC 3738, one of the most distinctive signs of ongoing star...
Sandy weakened to a Tropical Storm and strengthened back into a hurricane early on Saturday (Oct. 27), and its pressure was dropping, meaning that the storm is intensifying as it becomes an extra-tropical storm. NASA's TRMM satellite identified heavy rain falling within the system and NOAA's GOES satellites provided a picture of Sandy's massive...

Risk prediction models developed from an ancillary study of the Prostate Lung Colorectal and Ovarian Cancer Screening Trial may be useful in the public health sector for identifying individuals who are at risk for adverse smoking outcomes, such as relapse among former smokers and continued smoking among current smokers, and those who may benefit from relapse prevention and smoking cessation...
Researchers have found that children's brains are more affected by an inhaled anesthetic than an intravenous anesthetic with increased levels of brain lactate. Lactate increases brain activation and may lead to metabolic changes associated with anxiety and delirium. The findings provide new clues to metabolic changes within the brains of children undergoing anesthesia and could help researchers...
