Security researchers at the Georgia Tech Information Security Center (GTISC) have discovered a way to jailbreak current generation Apple iOS devices (e.g., iPhones and iPads) running the latest iOS software. The jailbreak, which enables circumvention of Apple's closed platform, was discovered by analyzing previously patched vulnerabilities with incomplete fixes.

It shows that quick workarounds mitigating only a subset of a multi-step attack leave these devices vulnerable to exploitation. Patching all vulnerabilities for a modern, complex software system (i.e., Windows and iOS) is often difficult due to the volume of bugs and response-time requirements.


Researchers from the University of Bradford say they have devised a simple blood test that will enable doctors to rule out cancer in patients presenting with certain symptoms, saving time and preventing costly and unnecessary invasive procedures such as colonoscopies and biopsies being carried out. Alternatively, it could be a useful aid for investigating patients who are suspected of having a cancer that is currently hard to diagnose. 

Early results have shown the method gives a high degree of accuracy diagnosing cancer and pre-cancerous conditions from the blood of patients with melanoma, colon cancer and lung cancer.  


Facebook, Google and just about everyone except Science 2.0 use global distributed computers to mine your web history and learn everything about you to generate revenue. Big data is being led by marketing, like many things are, but early adopters who make money at things create tools that everyone can then use, and that will be a big help for Science 2.0

New technologies for monitoring brain activity are generating unprecedented quantities of information. If it can ever be interpreted, that data may hold new insights into how the brain works. To help make sense of cranial Big Data, neuroscientists can now use Thunder, a library of tools developed at the Howard Hughes Medical Institute's Janelia Research Campus.


Magnetic random access memory (MRAM) is intriguing because of demand for fast, low-cost, nonvolatile, low-consumption, secure memory devices.

MRAM relies on manipulating the magnetization of materials for data storage rather than electronic charges, boasts all of these advantages as an emerging technology, but so far it hasn't been able to match flash memory in terms of storage density.


At various times, Alan Turing was hailed as a brilliant cryptologist, leading a team of code breakers at Bletchley Park which cracked the German Enigma machine cypher during World War II, and then later as a gay martyr. Now, due to popular media accounts of computers seeming 'human' over and over, he is known for The Turing Test and is getting a biopic, "The Imitation Game", starring Benedict Cumberbatch in the lead role.

In a 1950, Turing propose The Turing Test, where he outlined a standard for a computer being considered human and proposed that the solution to artificial intelligence would be a program with the mind of a child and teach it to think.  So the goal of the test is not to determine if a machine is correct, but whether or not it is considered real.

Scientists have developed a scalable, next-generation platelet bioreactor to generate fully functional human platelets in vitro


A new single-cell technique can help investigate how the environment affects our development and the traits we inherit from our parents. It can be used to map all of the 'epigenetic marks' on the DNA within a single cell,which will boost understanding of embryonic development, enhance clinical applications like cancer therapy and even reduce the number of mice used in research.



A site called Social Predictor (sociadictor.com) predicts future trends based on the number of tweets, sentiment of tweets, number of news stories and sentiment of the news stories about celebrities and culture. It can also try and predict stock prices or daily sales of a product, based on the chatter related to user-input keywords, such as a stock ticker or the name.

The creators said trading strategy based on their model outperformed other baseline strategies by between 1.4 percent and nearly 11 percent and did better than the Dow Jones Industrial Average during a four-month simulation. 

Scientists from Queen Mary University of London have found a successful way of identifying bird sounds from large audio collections, by using recordings of individual birds and of dawn choruses to identify characteristics of bird sounds.

They took advantage of large datasets of sound recordings provided by the British Library Sound Archive, and online sources such as the Dutch archive Xeno Canto.


The Affordable Care Act and data portability is forcing health care providers, and the vendors who service them, to accelerate development of tools that can handle an expected deluge of data and information about patients, providers and outcomes.

The volume of data is daunting - so are concerns about interoperability, security and the ability to adapt rapidly to the lessons in the data, writes Dana Gardner at Big Data Journal.

That is why Boundaryless Information Flow, Open Platform 3.0 adaptation, and security for the healthcare industry are headline topics for The Open Group’s upcoming event, Enabling Boundaryless Information Flow on July 21 and 22 in Boston, he notes.
