New kind of transistor could shrink communications devices on smartphones

One month after announcing a ferroelectric semiconductor at the nanoscale thinness required for modern computing components, a team has now demonstrated a reconfigurable transistor using that material. Their work paves the way for single amplifiers that can do the work of multiple conventional amplifiers, among other possibilities.

Incident atrial fibrillation appears to heighten dementia risk

People with a recent diagnosis of atrial fibrillation (AF), the most common irregular heart rhythm, have a modestly higher risk of developing dementia than people without the condition, according to new research. The research involved nearly 197,000 patient records from Kaiser Permanente health systems in California. Half of the patients had been recently diagnosed with atrial fibrillation; their...

A pool at Yellowstone is a thumping thermometer

Doublet Pool's regular thumping is more than just an interesting tourist attraction. A new study shows that the interval between episodes of thumping reflects the amount of energy heating the pool at the bottom, as well as in indication of how much heat is being lost through the surface. Doublet Pool, the authors found, is Yellowstone's thumping thermometer.

A surprising way to trap a microparticle

New study finds obstacles can trap rolling microparticles in fluid. Through simulations and experiments, physicists attribute the trapping effect to stagnant pockets of fluid, created by hydrodynamics. Random motions of the molecules within the fluid then 'kick' the microroller into a stagnant pocket, effectively trapping it.

Flat plate bow covers pave way for more economical shipping by improving ship aerodynamics

Ships are the main modes of transport for global trade as they are efficient and effective. Improving the aerodynamic performance of ship could reduce fuel consumption and improve speed, further improving the economics of shipping. Recently, researchers from have demonstrated that flat plate bow covers on ships can reduce overall wind drag in ships by nearly 40%, which could lead to enormous fuel...

Olive oil by-product could aid exercise

New research has found that olive fruit water, a by-product typically thrown away during olive oil production, could have exercise benefits. The study tested olive fruit water during exercise and found it had positive effects on several key markers of running performance.

Two-pronged immunotherapy eliminates metastatic breast cancer in mice

Researchers have identified a way to treat the area surrounding breast tumors that have spread to bone so that such tumors become vulnerable to attack by the body's immune system. When the researchers boosted the activity of certain immune cells, called T cells and macrophages, these immune cells worked together to clear metastatic breast tumors that had spread to the bones of mice.

Artificial intelligence (AI) reconstructs motion sequences of humans and animals

Imagine for a moment, that we are on a safari watching a giraffe graze. After looking away for a second, we then see the animal lower its head and sit down. But, we wonder, what happened in the meantime? Computer scientists have found a way to encode an animal's pose and appearance in order to show the intermediate motions that are statistically likely to have taken place.

Whether born naturally or via Cesarean section, babies receive essential microbes from their mothers

Do cesarean-born babies miss out on essential microbes? New evidence suggests that the answer may be 'no.' Researchers report that mothers are able to transfer microbes to their babies via alternative, compensatory routes. While cesarean-born babies do receive less of their mother's gut microbiome during birth, they make up for this by drinking their mother's microbes in breastmilk.

Viable superconducting material created

In a historic achievement, researchers have created a superconducting material at both a temperature and pressure low enough for practical applications. 'With this material, the dawn of ambient superconductivity and applied technologies has arrived,' according to a team of mechanical engineers and physicists.

Potential new therapeutic target for inflammatory diseases such as lupus and sepsis

Scientists have made an important breakthrough in understanding what goes wrong in our bodies during the progression of inflammatory diseases and -- in doing so -- unearthed a potential new therapeutic target. The scientists have found that an enzyme called fumarate hydratase is repressed in macrophages, a frontline inflammatory cell type implicated in a range of diseases including lupus,...

How moms are taking the lead in shaping children's education

A new global study, which takes a gender-sensitive approach, has found that a mother's educational status plays an increasingly important role in shaping their children's educational status, while the importance of the father's educational status has declined. Education expansion was expected to create greater social mobility around the world, but new global evidence from Lancaster University and...
