Children learn by imitating adults and will change what they know about an object to mimic adult behavior. Watching an adult do something wrong, or in a disorganizedor inefficient way, can make it much harder for a child to learn to do it right.
Scientists have identified a molecular 'switch'that, when blocked, may help reverse necrotizing enterocolitis, a leading cause of death in premature infants.
Researchers have developed new biocompatible polymeric materials that have many applications in the medical surgery and the biodegradable materials fields. Polymeric biomaterials derived from lactic acid have extensive uses in medical applications, especially in the context of biodegradable sutures. They are widely used in the architecture of cardiac tissue, as support for drugs, and biodegradable fixation devices for the repair of small broken bones such as the ones in the hands, joints and feet.
The vast majority of incidentally found adrenal masses identified in CT scans in patients without known malignancy are benign. 1,045 of the 1,049 adrenal masses were confirmed to be benign and clinically insignificant.
Engineers have demonstrated a highly versatile, compact and portable Quantum Cascade Laser sensor for the fast detection of a large number of chemicals, ranging from infinitesimal traces of gases to liquids, by broad tuning of the emission wavelength. The potential range of applications is huge, including homeland security, medical diagnostics such as breadth analysis, pollution monitoring, and environmental sensing of the greenhouse gases responsible for global warming.
New research has found that, contrary to common belief, young adults who maintain a close or moderate relationship with their parents exhibit greater independence in their personal lives than those who have a distant relationship.
By making the skeletal muscles of mice use energy less efficiently, researchers report that they have delayed the animals'deaths and their development of age-related diseases, including vascular disease, obesity, and one form of cancer. Those health benefits, driven by an increased metabolic rate, appear to come without any direct influence on the aging process itself, according to the researchers.
Hospitalizations related to a potentially deadly, antibiotic-resistant "superbug"more than doubled between 1999 and 2005, soaring from 127,000 to nearly 280,000, according to a new study. The study is the first to examine the recent magnitude and trends related to methicillin-resistant Staphylococcus aureus, or MRSA, infections. It also found that hospitalizations of patients with general staph infections increased 62 percent across the country.
The UK's toad population could be facing a bleak future because of a deadly fungal disease. The deadly chytrid fungus Batrachochytrium dendrobatidis (Bd) is highly effective at causing extinctions among local populations of amphibians and it has already wiped out vast numbers of amphibians in areas including Australia and South America.
A new classification system of rare lung diseases in infants is improving diagnosis and treatment. The system clears up considerable confusion about how to classify and treat diseases that are rarely seen by most doctors and pathologists.
When fruit fly larvae are poked or prodded, they fold themselves up and corkscrew their bodies around, a behavior that appearsto be the young insects'equivalent of a "judo move,"say researchers. They now trace that rolling behavior to neurons resembling those that sense pain.
As cold and flu season hits this year amid growing debate over the necessity of vaccinations, researchers have uncovered widespread misinformation in related videos on YouTube. Researchers found that more than half of the videos portrayed childhood, HPV, flu and other vaccinations negatively or ambiguously.
A dwarf star with a surprisingly magnetic personality and a huge hot spot covering half its surface area is showing astronomers that life as a cool dwarf is not necessarily as simple and quiet as they once assumed. Simultaneous observations made by four of the most powerful Earth- and space-based telescopes revealed an unusually active magnetic field on the ultracool low-mass star TVLM513-46546.
This study is the first to identify protein pheromones responsible for the aggression response in male mice. The findings could provide a tool for understanding the neural pathways that play a role in human behavior.
