Spintronic memory cells for neural networks

In recent years, researchers have proposed a wide variety of hardware implementations for feed-forward artificial neural networks. These implementations include three key components: a dot-product engine that can compute convolution and fully-connected layer operations, memory elements to store intermediate inter and intra-layer results, and other components that can compute non-linear activation functions.

Psoriasis patients turn to alternative medicine when traditional treatments fail

Patients with psoriasis frequently use complementary or alternative therapies to treat their symptoms, according to survey results published by dermatologists from the George Washington University (GW) in the Journal of the American Academy of Dermatology.

Imaging results, health data combine in AI model to predict breast cancer

Women know the drill: Breast cancer is too commonly a cancer diagnosis to be ignored, as early detection could make a difference. While false positives may cause an enormous amount of undue stress, false negatives have an impact on how early a cancer is detected and subsequently treated.

New research provides medical proof vacation is good for your heart

We all treasure our vacation time and look forward to that time when we can get away from work. With the arrival of summer comes the prime vacation season and along with it one more reasons to appreciate our vacation time: the value to our heart health. While there has been much anecdotal evidence about the benefits of taking a vacation from work, a new study by Syracuse University professors Bryce Hruska and Brooks Gump and other researchers reveals the benefits of a vacation for our heart health.

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.

Artificial intelligence identifies 'kissing bugs' that spread Chagas disease

New research from the University of Kansas shows machine learning is capable of identifying insects that spread the incurable disease called Chagas with high precision, based on ordinary digital photos. The idea is to give public health officials where Chagas is prevalent a new tool to stem the spread of the disease and eventually to offer identification services directly to the general public.

One third of Cambodians infected with threadworm, study finds

Strongyloides stercoralis is a soil-transmitted threadworm that is endemic in many tropical and subtropical areas of the world. Now, researchers reporting in PLOS Neglected Tropical Diseases have conducted a nation-wide parasitology survey of the Cambodian population and concluded that nearly a third of the studied population is infected with S. stercoralis.

Team proposes stochastic model to explain microbiome composition

All living things—from the simplest animal and plant organisms to the human body—live closely together with an enormous abundance of microbial symbionts, which colonise the insides and outsides of their tissues. The functional collaboration of host and microorganisms, which scientists refer to as a metaorganism, has only recently come into the focus of life science research. Today we know that we can only understand many of life's processes in connection with the interactions between organism and symbionts. The Collaborative Research Centre (CRC) 1182 "Origin and Function of Metaorganisms" at Kiel University (CAU) aims to understand the communication and the functional consequences of host-microbe relationships.

Research team supersizes 'quantum squeezing' to measure ultrasmall motion

Physicists at the National Institute of Standards and Technology (NIST) have harnessed the phenomenon of "quantum squeezing" to amplify and measure trillionths-of-a-meter motions of a lone trapped magnesium ion (electrically charged atom).

Researchers confirm that narwhals and belugas can interbreed

A team of University of Copenhagen researchers has compiled the first and only evidence that narwhals and beluga whales can breed successfully. DNA and stable isotope analysis of an anomalous skull from the Natural History Museum of Denmark has allowed researchers to confirm the existence of a narwhal-beluga hybrid.

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.

Scaffold helps cells repair torn meniscus in lab tests

About a million times a year, Americans with a torn meniscus in their knee undergo surgery in hopes of a repair. Certain tears can't be fixed or won't heal well, and many patients later suffer osteoarthritis from the injury.
