Controls engineers have developed practical strategies for building and coordinating scores of sensor-laden balloons within hurricanes. Using onboard GPS and cellphone-grade sensors, each drifting balloon becomes part of a 'swarm' of robotic vehicles, which can periodically report, via satellite uplink, their position, the local temperature, pressure, humidity and wind velocity.

Sperm are constantly replenished in the adult male body. Understanding the workings of stem cells responsible for this replenishment is expected to shed light on why male fertility diminishes with age, and possibly lead to new treatments for infertility.

Entomologists report nine newly identified species of the desert bee genus Perdita, including two species with 'ant-like' males completely different in appearance from their mates.

After all the lifting, hauling and wrapping, worn out gift givers may blame the season’s physical strain for any shoulder soreness they are feeling. It turns out there could be another reason. A new study finds that individuals with symptoms that put them at increased risk for heart disease could be more likely to have shoulder problems, including joint pain and rotator cuff injury.

Researchers have investigated how neuronal activity influences cAMP response element binding protein (CREB) dynamics.

Scientists report a new molecular mechanism that could explain the cause of some autoimmune diseases.

A combination of a diabetes medication and an antihypertensive drug can effectively combat cancer cells. The team of researchers has also reported that specific cancer cells respond to this combination of drugs.

Patients with complex diseases have a higher risk of developing another. Multi-morbidity represents a huge problem in everyday clinical practice, because it makes it more difficult to provide successful treatment. By analysing data from all over Austria, scientists have managed to develop a mathematical model that can be used to distinguish whether a disease has a genetic or environmental cause.

Scientists have discovered that cadherin clusters, which are well known for forming junctions between cells, also play a role in stabilizing the cell cortex.

New research reveals role for calcium ions in chromosome condensation during mitosis; high-resolution imaging of living cells reveals compact, globular chromosomes in the presence of calcium that became fibrous and expand in its absence.

Using a mouse model, scientists have identified a sugar molecule that reduced the inflammatory response and progress of emphysema, a common component of chronic obstructive pulmonary disease (COPD). This discovery could lead to the development of drugs based on glycans -- biological sugar molecules -- for the treatment of diseases such as COPD, which is the fourth leading cause of death worldwide.

About half of US children with special health care needs -- 5.6 million children -- receive medical care from uncompensated family members worth billions of dollars, finds a large national study. The study is the first to systematically track parents' unpaid time providing care, as well as lost income due to parents taking time off from work.

Missions at sea, in mountainous regions or close to skyscrapers are extremely risky for helicopter pilots. The turbulent air flows near oil rigs, ships, cliffs and tall buildings can throw a helicopter off balance and cause a crash. To provide pilots with optimal preparation for these challenging conditions, engineers are developing new simulation software.

A new study demonstrates that automated monitoring systems that identify 'regime shifts' -- such as rapid growth of algae and then depletion of oxygen in the water -- can successfully predict full-scale algae blooms in advance, and help resource managers avert their development.

New details about a key cellular protein could lead to treatments for neurodegenerative diseases, such as Parkinson's, Huntington's, Alzheimer's, and ALS. At their root, these disorders are triggered by misbehaving proteins in the brain. The proteins misfold and accumulate in neurons, eventually killing the cells. In a new study, researchers used a different protein, Nrf2, to restore levels of the disease-causing proteins to a normal, healthy range, thereby preventing cell death.

A new study confirms that the iconic cheetah is sprinting towards extinction.

Researchers used highly sophisticated brain imaging tools and computational methods to measure the real-time brain processes that convert the appearance of a face into the recognition of an individual. They are hopeful that the findings might be used in the near future to locate the exact point at which the visual perception system breaks down in different disorders and injuries, ranging from developmental dyslexia to prosopagnosia, or face blindness.
