Transforming how complex marine data is synthesized

Transforming how complex marine data is synthesized
In 2012, scientists at UC Santa Barbara's National Center for Ecological Analysis and Synthesis (NCEAS) launched the Ocean Health Index (OHI), a scientific framework to measure and track the health of the world's oceans. Working in partnership with the nonprofit Conservation International, the OHI team measured the combined benefits that oceans sustainably provide for people -- from wild-caught and farmed seafood to habitats that protect coastlines. Annual status reports show how and where to im…

Network traffic provides early indication of malware infection

Network traffic provides early indication of malware infection
By analyzing network traffic going to suspicious domains, security administrators could detect malware infections weeks or even months before they're able to capture a sample of the invading malware, a new study suggests. The findings point toward the need for new malware-independent detection strategies that will give network defenders the ability to identify network security breaches in a more timely manner. The strategy would take advantage of the fact that malware invaders need to communicat…

A fresh math perspective opens new possibilities for computational chemistry

A fresh math perspective opens new possibilities for computational chemistry
Glow-in-the-dark objects seem magical when you're a kid -- they can brighten up a dark room without the need for electricity, batteries or a light bulb. Then at some point you learn the science behind this phenomenon. Chemical compounds called chromophores become energized, or excited, when they absorb visible light. As they return to their normal state, the stored energy is released as light, which we perceive as a glow. In materials science, researchers rely on a similar phenomenon to study th…

Statistical safeguards in data analysis and visualization software

Statistical safeguards in data analysis and visualization software
Modern data visualization software makes it easy for users to explore large datasets in search of interesting correlations and new discoveries. But that ease of use -- the ability to ask question after question of a dataset with just a few mouse clicks -- comes with a serious pitfall: it increases the likelihood of making false discoveries. At issue is what statisticians refer to as "multiple hypothesis error." The problem is essentially this: the more questions someone asks of a dataset, they m…

Data sharing can offer help in science's reproducibility crisis

Data sharing can offer help in science
Criticism that researchers in the psychological and brain sciences are failing to reproduce studies -- a key step in the scientific method -- may have more to do with the complexity of managing data, rather than an attempt to hide methods and results, according to researchers. However, without greater focus on reproducibility, scientists will likely continue to face questions about the reliability of their research. "What we researchers try to do is provide the science-consuming public with genu…

Technology edits voices like text

Technology edits voices like text
Anyone who ever used a typewriter will recall the difficulty of fixing a misspelled or poorly chosen word -- remember whiteout and correction tape? Now, technology developed by Princeton University computer scientists may do for audio recordings of the human voice what word processing software did for the written word. The software, named VoCo, provides an easy means to add or replace a word in an audio recording of a human voice by editing a transcript of the recording. New words are automatica…

The digitization of medical knowledge

The digitization of medical knowledge
Researchers from Charité -- Universitätsmedizin Berlin have challenged traditional teaching and learning concepts employed in medical training. A comparison with conventional learning methods led them to conclude that tablet-based, multimedia-enhanced training improves medical examination results. Their study, which has been published in the journal PLOS ONE*, clearly shows that an integrated program of tablet-based theoretical training and clinical practice enhances medical training. The use of…

Operating smart devices from the space on and above the back of your hand

Operating smart devices from the space on and above the back of your hand
It relies on a depth sensor that tracks movements of the thumb and index finger on and above the back of the hand. In this way, not only can smartwatches be controlled, but also smartphones, smart TVs and devices for augmented and virtual reality. They're called the "Apple Watch Series 2," "LG Watch," "Samsung GEAR S3" or "Moto 360 2nd Gen" but they all have the same problem. "Every new product generation has better screens, better processors, better cameras, and new sensors, but regarding input…

Gender bias in open-source programming

Gender bias in open-source programming
A study comparing acceptance rates of contributions from men and women in an open-source software community finds that, overall, women's contributions tend to be accepted more often than men's -- but when a woman's gender is identifiable, they are rejected more often. "There are a number of questions and concerns related to gender bias in computer programming, but this project was focused on one specific research question: To what extent does gender bias exist when pull requests are judged on Gi…

Device allows users to manipulate 3-D virtual objects more quickly

Device allows users to manipulate 3-D virtual objects more quickly
Researchers at North Carolina State University have developed a user-friendly, inexpensive controller for manipulating virtual objects in a computer program in three dimensions. The device allows users to manipulate objects more quickly -- with less lag time -- than existing technologies. The device, called CAPTIVE, offers six degrees of freedom (6DoF) for users -- with applications ranging from video gaming to medical diagnostics to design tools. And CAPTIVE makes use of only three components: …
