UMD researchers develop tool to better visualize, analyze human genomic data
Scientists at the University of Maryland have developed a new, web-based tool that enables researchers to quickly and easily visualize and compare large amounts of genomic information resulting from high-throughput sequencing experiments.

Atlantic origin of recent Pacific trade wind, sea level and temperature trends
Climate models predict that the equatorial Pacific trades should weaken with increasing greenhouse gases; yet since the 1990s, satellites and climate stations show they have strengthened, resulting in accelerated sea level rise in the western Pacific and in both Pacific and global climate change.

Primary care telephone triage does not save money or reduce practice workload
A new large study, published in The Lancet on Aug.

Scientists unveil unique approach to the basic concepts of solid state physics
The fundamental properties of solids depend critically on how the atomic constituents of the material are arranged and on their motion about their equilibrium positions.

Making sense of scents
Exactly how animals separate the smells of objects of interest, such as food sources or the scent of predators, from background information has remained largely unknown.

Researchers find potential new predictor of stress-related illnesses
Many scientists believe that the tendency to develop stress-related disorders is an inherited trait or is the result of exposure to traumatic events.

Small DNA modifications predict brain's threat response
Epigenetic changes to a gene that is well known for its involvement in clinical depression and posttraumatic stress disorder can affect the way a person's brain reacts to threats, according to a new study by Duke University researchers.

Kangaroos win when Aborigines hunt with fire
Australia's Aboriginal Martu people hunt kangaroos and set small grass fires to catch lizards, as they have for at least 2,000 years.

Uncovering the 3-D structure of a key neuroreceptor
EPFL scientists reveal for the first time the 3-D structure of a crucial neuroreceptor.

Australian Twitter accounts hit 2.8 million
The world's first comprehensive survey of the global and Australian Twitterspheres has clocked Australian Twitter accounts at 2.8 million by September 2013.

Fault trumps gruesome evidence when it comes to punishment
A new brain imaging study has identified the mechanisms involved in balancing blameworthiness and the emotion-driven urge to punish.

Study finds new genetic risk markers in pancreatic cancer
A large DNA analysis of people with and without pancreatic cancer has identified several new genetic markers that signal increased risk of developing the highly lethal disease, report scientists from Dana-Farber Cancer Institute.

New trick for 'old' drug brings hope for pancreatic cancer patients
Scientists have found a new use for an old drug by showing that it shrinks a particular type of pancreatic cancer tumor and stops it spreading.

Rare developmental disorder linked to tumor-suppressing protein, Stanford researchers find
A protein known for its tumor-suppressing properties can also trigger developmental disorders, including CHARGE syndrome, according to researchers at the Stanford University School of Medicine.

Atlantic warming turbocharges Pacific trade winds
Rapid warming of the Atlantic Ocean, likely caused by global warming, has turbocharged Pacific Equatorial trade winds.

Tumor suppressor mutations alone don't explain deadly cancer
Although mutations in a gene dubbed 'the guardian of the genome' are widely recognized as being associated with more aggressive forms of cancer, researchers at the University of California, San Diego School of Medicine have found evidence suggesting that the deleterious health effects of the mutated gene may in large part be due to other genetic abnormalities, at least in squamous cell head and neck cancers.

Self-assembling anti-cancer molecules created in minutes
Researchers have developed a simple and versatile method for making artificial anti-cancer molecules that mimic the properties of one of the body's natural defense systems.

Knowing what to keep and what to trash: How an enzyme distinguishes cellular messages
In the cell, proteins read through messages to distinguish what needs to be saved and what needs to be discarded.
