#US House rejects NSA phone data trawl The US House of representatives has voted to end the National security agency's bulk collection of Americans'phone records.
The bill would empower the agency to search data held by telephone companies on a case-by-case basis. Bulk collection was revealed in 2013 by ex-security contractor Edward Snowden.
The amendments would ban the agency's mass collection of telephone data-phone numbers, time and duration of calls-as well as emails and web addresses."
Printing the drug meant it could package up to 1, 000 milligrams into individual tablets. The 3d printed pill dissolves in the same manner as other oral medicines.
Being able to 3d print a tablet offers the potential to create bespoke drugs based on the specific needs of patients,
"For the last 50 years we have manufactured tablets in factories and shipped them to hospitals
and for the first time this process means we can produce tablets much closer to the patient, "said Dr Mohamed Albed Alhnan, a lecturer in pharmaceutics at the University of Central Lancashire.
It would mean that medical institutions could adjust the dose for individual patients with just a simple tweak to the software before printing.
printers are adapted to produce pharmaceutical compounds rather than polymers which are used more usually. Such methods are already proving very useful in healthcare with doctors using the system to create customised implants for patients with injuries or other conditions.

#Ashley Madison passwords cracked More than 11 million passwords stolen from the Ashley Madison infidelity dating website have been decoded,
When stolen data from the site was dumped first, the encrypted passwords were said to be almost uncrackable because of the way they were scrambled.
But programming changes by the site's developers meant more than a third of the passwords were protected poorly.
The Ashley Madison website was breached by a group of hackers called The Impact Team which stole gigabytes of data including login names and passwords of more than 30 million users.
Initial analysis of the data dump showed that the passwords were stored on a database after they had been protected using a process known as hashing that employs the bcrypt algorithm.
The way this scrambles passwords makes it hard to carry out so-called"brute force"attacks that try lots of different word
and letter combinations because hashing with bcrypt takes a lot of computer power. As a result a brute force attack on the passwords would take years.
However, an amateur password cracking group called Cynosure Prime looking through code also stolen from Ashley Madison realised that at some point the site changed the way passwords were stored.
In a blogpost, the group said it had found two insecure functions in the site code that meant it was"able to gain enormous speed boosts in cracking the bcrypt hashed passwords".
and changes the site made to passwords when they were entered by users. By focussing on these vulnerable steps the group has managed already to decipher 11.2 million passwords
and is hopeful it can crack a total of more than 15 million which were scrambled with the insecure functions.
The remaining passwords from the site are not susceptible to this attack because they were hashed by code lacking the insecure functions.
The group said it would not be releasing the passwords it had recovered to"protect end users".
It speculated to news site Ars Technica that the insecure hashing system was introduced to ensure that users could log in to the site quickly y

Mr Zuckerberg, keen as ever to expand Facebook's user base and global influence, talked up the prospect of connecting a billion more Indians to the internet.

MRI data consist of a series of cross sections of a three-dimensional object. Like a black-and-white photograph, each cross section has regions of dark and light,
Determining the boundaries between distinct objects in an image is one of the central problems in computer vision
But general-purpose image-segmentation algorithms aren reliable enough to produce the very precise models that surgical planning requires.
Human factors Typically, the way to make an image-segmentation algorithm more precise is to augment it with a generic model of the object to be segmented.
That anatomical consistency could give a segmentation algorithm a way to weed out improbable conclusions about object boundaries.
and allow algorithms to take over from there. Their strongest results came when they asked the expert to segment only a small patch ne-ninth of the total area of each cross section.
and letting the algorithm infer the rest yielded 90 percent agreement with expert segmentation of the entire collection of 200 cross sections.
Prognosis Currently, the algorithm examines patches of unsegmented cross sections and looks for similar features in the nearest segmented cross sections.
This and other variations on the algorithm are the subject of ongoing research. The clinical study in the fall will involve MRIS from 10 patients who have received already treatment at Boston Children Hospital.
Each of seven surgeons will be given data on all 10 patients some probably, more than once. That data will include the raw MRI scans and, on a randomized basis,
either a physical model or a computerized 3-D model, based, again at random, on either human segmentations or algorithmic segmentations.
Using that data, the surgeons will draw up surgical plans, which will be compared with documentation of the interventions that were performed on each of the patients.

#Computer system Being developed to Predict Change In The Alzheimer's Brain, MIT Study MIT researchers are developing a computer system that uses genetic, demographic,
and clinical data to help predict the effects of disease on brain anatomy. In experiments, they trained a machine-learning system on MRI data from patients with neurodegenerative diseases
and found that supplementing that training with other patient information improved the system predictions. In the cases of patients with drastic changes in brain anatomy, the additional data cut the predictionserror rate in half,
from 20 percent to 10 percent. his is the first paper that wee ever written on this,

This included data on genetic markers known as single-nucleotide polymorphisms; demographic data, such as subject age, gender, marital status, and education level;
and rudimentary clinical data, such as patientsscores on various cognitive tests. The brains of healthy subjects and subjects in the early stages of neurodegenerative disease change little over time,
and indeed, in cases where the differences between a subject scans were slight, the system trained only on MRI data fared well.
In cases where the changes were marked more, however, the addition of the supplementary data made a significant difference.
Counterfactuals In the second experiment, the researchers trained the system just once, on both the MRI data and the supplementary data of healthy subjects.
But they instead used it to predict what the brains of Alzheimer patients would have looked like had they not been disfigured by disease.
