Stringing together meaningless sounds to create meaningful signals was previously thought to be the preserve of humans alone, but a new study has revealed that babbler birds are also able to communicate in this way.
A newly-identified species of spike-covered worm with legs, which lived 500 million years ago, was one of the first animals on Earth to develop armor for protection.
Researchers report their findings of just how a certain tumor-suppressing protein helps prevent colon cancer. With this discovery, researchers believe they’ve found a possible drug target for colon cancer patients who lack the tumor suppressor.
Laboratories that test chemicals for neurological toxicity could reduce their use of laboratory mice and rats by replacing these animal models with tiny aquatic flatworms known as freshwater planarians, scientists say.
SMA is a devastating neuromuscular disorder that robs children of their ability to walk, eat, or breathe. Mostly caused by an inherited flaw in the Survival Motor Neuron (SMN) gene, SMA is presently without a cure. Scientists have shown that fruit flies and brewer's yeast can reveal clues about this disorder.
Chemists have demonstrated that creating bacterial 'fight clubs' is an effective way to discover natural molecules with the potential to become new drugs. The "fight club" approach applies analytical tools to analyze what happens when microbes compete.
Scientists have described how glasses form at the molecular level and provided a possible solution to a problem that has stumped scientists for decades.
Researchers have developed a new system that repairs dangerous software bugs by automatically importing functionality from other, more secure applications.
Ambulance services should be assessed on how reassured patients and their families feel during an emergency as well as on response times, researchers have found. Offering reassurance to patients and their families alleviates anxiety, fear or panic. These aspects of care can be as important as other performance measures such as response times, the study said.
New animal research reveals fundamental sex differences in how pain is processed. These findings have far-reaching implications for our basic understanding of pain, how we develop the next generation of medications for chronic pain--which is by far the most prevalent human health condition--and the way we execute basic biomedical research using mice.
Intense visual input forces the brain into a brief moment of chaos, but the visual cortex spontaneously returns the brain to its optimal function, physicists have found. The finding advances fundamental understanding of how a healthy visual system processes information.
Tiny microscopic animals called zooplankton are ingesting plastic particles at an alarming rate, according to a new study. That could not only pose a risk to salmon but also spell trouble for the entire aquatic food web -- from zooplankton to humpback whales.
A new technique for discovering potentially dangerous drug interactions--before they show up in medical databases like PubMed-- has been developed by researchers. It includes the searching millions of tweets on Twitter.
New research hopes to close the debate on whether a major mud volcano disaster in Indonesia was triggered by an earthquake or had human-made origins.
American adults and adolescents are now significantly more accepting of mothers who work fulltime, but a growing minority from younger generations believe that wives should mind the household and husbands should make decisions for the family, according to new research.
A scoring system that can identify periods of high activity and increased trauma patient deaths in hospital emergency rooms may help hospitals better prepare for surges in trauma patient volume that come with catastrophic events like the Boston Marathon bombing (April 2013) or disasters like the Amtrak train crash (May 2015) in Philadelphia, according to a study.
Leading experts in the field present the latest research on material properties of bone and how these can impart resilience or fragility to the skeleton. This new knowledge will aide in understanding both the hierarchical structure of bone and its importance to overall bone health.
Will the Tour de France prologue in Utrecht get the winner it deserves? New aerodynamic research shows that riders in a time trial can save vital seconds by riding closer to the following team car. Over a short distance like the prologue of the Tour de France, that can save as much as 6 seconds: enough to make the difference between winning and losing.
Making carbon-carbon bonds continues to be an important strategy to synthesize useful pharmaceuticals, agrochemicals and organic materials. Chemists have now expanded the scope of a Nobel Prize-winning carbon-carbon bond forming reaction...Show More Summary
The usage of key medicines in developing countries could be significantly increased through improved packaging appearance.
