Chronic kidney disease epidemic may be result of high heat, toxins

A mysterious epidemic of chronic kidney disease among agricultural workers and manual laborers may be caused by a combination of increasingly hot temperatures, toxins and infections, according to researchers at the University of Colorado Anschutz Medical Campus.

Using AI to predict breast cancer and personalize care

Despite major advances in genetics and modern imaging, the diagnosis catches most breast cancer patients by surprise. For some, it comes too late. Later diagnosis means aggressive treatments, uncertain outcomes, and more medical expenses. As a result, identifying patients has been a central pillar of breast cancer research and effective early detection.

Design flaws create security vulnerabilities for 'smart home' internet-of-things devices

Researchers at North Carolina State University have identified design flaws in "smart home" Internet-of-Things (IoT) devices that allow third parties to prevent devices from sharing information. The flaws can be used to prevent security systems from signaling that there has been a break-in or uploading video of intruders.

VisiBlends, a new approach to disrupt visual messaging

Visual blends, which join two objects in an unusual, eye-catching way, are an advanced graphic design technique used in advertising, marketing, and the media to draw attention to a specific message. These visual marriages are designed to precipitate an "aha!" moment in the viewer who grasps one idea from the union of two images. For instance, blending an image of an orange with an image of the sun could convey a beverage with Vitamin C.

Two-thirds of world's longest rivers throttled by mankind: study

Almost two in three of Earth's longest rivers have been severed by dams, reservoirs or other manmade constructions, severely damaging some of the most important ecosystems on the planet, researchers said Wednesday.

An approach for securing audio classification against adversarial attacks

Adversarial audio attacks are small perturbations that are not perceivable by humans and are intentionally added to audio signals to impair the performance of machine learning (ML) models. These attacks raise serious concerns about the security of ML models, as they can cause them to make mistakes and ultimately generate wrong predictions.

New chip stops attacks before they start

A new computer processor architecture developed at the University of Michigan could usher in a future where computers proactively defend against threats, rendering the current electronic security model of bugs and patches obsolete.

Why some red wines taste 'dry'

Wine connoisseurs can easily discriminate a dry red wine, such as Cabernet Sauvignon, from a fruitier red, like Pinot Noir. Scientists have long linked the "dryness" sensation in wine to tannins, but how these molecules create their characteristic mouthfeel over time is not fully understood. Now, researchers reporting in ACS' Journal of Agricultural and Food Chemistry have found that tannin structure, concentration and interactions with saliva and other wine components influence the perception of dryness.

How do you find a virus that's completely unknown? Study says, look to the genome

Viruses, the most abundant biological entities on earth, are a scourge on humanity, causing both chronic infections and global pandemics that can kill millions. Yet, the true extent of viruses that infect humans remains completely unknown. Some newly discovered viruses are recognized because of the sudden appearance of a new disease, such as SARS in 2003, or even HIV/AIDS in the early 1980s. New techniques, however, now enable scientists to identify viruses by directly studying RNA or DNA sequences in genetic material associated with humans, enabling detection of whole populations of viruses—termed the virome—including those that may not cause acutely recognizable disease. However, identifying novel types of viruses is difficult as their genetic sequences may have little in common with already known viral genomes that are available in reference databases.

Show your hands: Smartwatches sense hand activity

We've become accustomed to our smartwatches and smartphones sensing what our bodies are doing, be it walking, driving or sleeping. But what about our hands? It turns out that smartwatches, with a few tweaks, can detect a surprising number of things your hands are doing.

Scientists investigate dwarf planet's ring

Discovered in 2004, Haumea is a dwarf planet located beyond Pluto's orbit in a region of the solar system called the Kuiper Belt. Pluto was demoted from the category of fully fledged planets in 2006 because of the discovery of Haumea and other dwarf planets.

Australian doctors overprescribing flu antivirals

Australian doctors are prescribing antivirals for people with the flu who may not benefit, putting patients at risk of unnecessary side effects and potentially increasing the risk of antimicrobial resistance to these medications, researchers from the University of Adelaide have found.

Supply-chain hack attacks are worrying investigators

What do you know about supply-chain attacks? In January, an article in CSO said it's when a weak link in your enterprise security might lie with partners and suppliers. It's when someone infiltrates your system through an outside partner or provider with access to your systems and data.
