A new study of newborns treated with hypothermia for hypoxic-ischemic encephalopathy (HIE) - a condition that occurs when the brain is deprived of an adequate oxygen supply - confirms its neuroprotective effects on the brain.

Therapeutic hypothermia or targeted cooling of the brain is the first therapy for neuroprotection in neonates with HIE. Without treatment, these babies often develop cerebral palsy or other severe complications. World-wide, nearly one million babies will die and another million will be left with disabilities.

Scientists using NASA's Hubble Space Telescope have produced new maps of Jupiter -- the first in a series of annual portraits of the solar system's outer planets.

Collecting these yearly images -- essentially the planetary version of annual school picture days for children -- will help current and future scientists see how these giant worlds change over time. The observations are designed to capture a broad range of features, including winds, clouds, storms and atmospheric chemistry.

Already, the Jupiter images have revealed a rare wave just north of the planet's equator and a unique filamentary feature in the core of the Great Red Spot not seen previously.

Much like the flapping of a windsock displays the quick changes in wind's speed and direction, called turbulence, comet tails can be used as probes of the solar wind - the constant flowing stream of material that leaves the sun in all directions.

According to new studies of a comet tail observed by NASA's Solar and Terrestrial Relations Observatory, or STEREO, the vacuum of interplanetary space is filled with turbulence and swirling vortices similar to gusts of wind on Earth. Such turbulence can help explain two of the wind's most curious features: its variable nature and unexpectedly high temperatures.

Antipsychotic drugs are initiated in patients with Alzheimer's disease (AD) more frequently than in the general population - already 2-3 years before the Alzheimer's diagnosis, according to a new study from the University of Eastern Finland. Most commonly, antipsychotics were initiated during the six months following the Alzheimer's diagnosis; however, the incidence of new antipsychotic users was high also later on. 

A new challenges prevailing wisdom by identifying the atmosphere as the driver of a decades-long climate variation known as the Atlantic Multi-decadal Oscillation (AMO) and offering new insight on the causes and predictability of natural climate variations, which are known to cause wide-ranging global weather impacts, including increased rainfall, drought, and greater hurricane frequency in many parts of the Atlantic basin.

For decades, research on climate variations in the Atlantic has focused almost exclusively on the role of ocean circulation as the main driver, specifically the Atlantic Meridional Overturning Circulation, which carries warm water north in the upper layers of the ocean and cold water south in lower layers like a large conveyor belt.

Scientists have developed a blood test that could help pair cancer patients with the most suitable therapy for their disease and then track the tumor's progress to see if the treatment is working, according to research published today (Thursday) in Clinical Cancer Research.

Using the blood test throughout a patient's treatment gives a 'running commentary' of what is happening to tumors - giving scientists the lowdown on how well the treatment is working, how the cancer is changing and whether it is becoming resistant to treatment. It is the first time a blood test has been used in this way during clinical trials of targeted drugs, proving that the technique can monitor cancer simply and quickly.

Dopamine deficiency in the basal ganglia (a set of subcortical structures) causes severe motor dysfunctions, such as slowness of movements (bradykinesia), as observed in Parkinson's disease. Dopamine binds D1 and D2 receptors that are expressed in the nerve cells of the striatum (a structure of the basal ganglia), and exerts different effects on the nerve cells. However, how dopamine controls through these receptors the information flow in the basal ganglia and voluntary movements is still not clear.

Calcium is a crucial element in the body that controls thought, movement and other bodily functions. These events are directed by specialized proteins called ion channels that allow the flow of calcium ions in and out of cells and among cell compartments. For years, scientists have been unsure how calcium ion channels function.

New atomic scale images of the structure of calcium's gatekeeper, IP3R, could go a long way toward solving this mystery and lead to treatments for the many diseases tied to channel malfunctions.

The IP3R channel was imaged by scientists in the Department of Biochemisty and Molecular Biology at The University of Texas Health Science Center at Houston (UTHealth). Their findings appear in the journal Nature.
