SPFCNN-Miner: A new classifier to tackle class-unbalanced data

Researchers at Chongqing University in China have recently developed a cost-sensitive meta-learning classifier that can be used when the training data available is high-dimensional or limited. Their classifier, called SPFCNN-Miner, was presented in a paper published in Elsevier's Future Generation Computer Systems.

New e-tattoo enables accurate, uninterrupted heart monitoring for days

The leading cause of death in Texas is heart disease, according to the National Center for Health Statistics, accounting for more than 45,000 deaths statewide in 2017. A new wearable technology made from stretchy, lightweight material could make heart health monitoring easier and more accurate than existing electrocardiograph machines—a technology that has changed little in almost a century.

Signature of an ineffective immune response to cancer revealed

Our immune system is programmed to destroy cancer cells. Sometimes it has trouble slowing disease progression because it doesn't act quickly or strongly enough. In a study published in The Journal of Clinical Investigation, researchers from the University of Montreal Hospital Research Centre (CRCHUM) revealed the genetic signature of this failed immune response for the first time.

Algorithm quickly finds hidden objects in dense point clouds

A new MIT-developed technique enables robots to quickly identify objects hidden in a three-dimensional cloud of data, reminiscent of how some people can make sense of a densely patterned "Magic Eye" image if they observe it in just the right way.

Squeezing of blood vessels may contribute to cognitive decline in Alzheimer's

Reduced blood flow to the brain associated with early Alzheimer's may be caused by the contraction of cells wrapped around blood vessels, according to a UCL-led study that opens up a new way to potentially treat the disease.

Why climate change means a rethink of coffee and cocoa production systems

Global demand for coffee and cocoa is on the rise. Yet across the equatorial belt where these two crops are produced, the future is not looking bright. Climate change in the tropics is pushing coffee and cocoa closer to the limits of physiological tolerance and constraining the places where they can grow in the future.

Home-HIT might be the workout that brings quick, simple exercises to the masses

How much do you exercise? Government guidelines suggest that, in order to stay healthy, adults should perform at least 150 minutes of moderate aerobic activity every week—that's exercise that gets your breathing and heart rate up.

Crystal with a twist: scientists grow spiraling new material

With a simple twist of the fingers, one can create a beautiful spiral from a deck of cards. In the same way, scientists at the University of California, Berkeley, and Lawrence Berkeley National Laboratory (Berkeley Lab) have created new inorganic crystals made of stacks of atomically thin sheets that unexpectedly spiral like a nanoscale card deck.

State initiative to address disparities in mother's milk for very low birth weight infants

Researchers at Boston Medical Center initiated a statewide quality improvement imitative to increase mothers' ability to produce and provide milk for very low birth weight infants at their discharge, as well reduce the racial/ethnic disparities in milk production and provision to these infants. A new study, published June 18th in Pediatrics, indicates that the initiative yielded positive results on improving rates of prenatal human milk education, early milk expression and skin to skin care among mothers of very low birth weight infants during initial hospitalization, but did not lead to sustained improvement in mother's milk provision at hospital discharge.

Study: More aggressive treatments needed to improve 5-year survival rate for glioblastoma

Despite improvements in median and short-term survival rates for patients with glioblastoma, the most common brain tumor in adults, the percentage of patients achieving five-year survival remains low, according to new Mayo Clinic research.

Study predicts more long-term sea level rise from Greenland ice

Greenland's melting ice sheet could generate more sea level rise than previously thought if greenhouse gas emissions continue to increase and warm the atmosphere at their current rate, according to a new modeling study. The study, which used data from NASA's Operation IceBridge airborne campaign, was published in Science Advances today. In the next 200 years, the ice sheet model shows that melting at the present rate could contribute 19 to 63 inches to global sea level rise, said the team led by scientists at the Geophysical Institute at the University of Alaska Fairbanks. These numbers are at least 80 percent higher than previous estimates, which forecasted up to 35 inches of sea level rise from Greenland's ice.
