Brainflayer: A Password Cracker That Steals Bitcoins From Your Brain. For bitcoin fans, the notion of a “brain wallet” has long seemed like the ideal method of storing your cryptocurrency: By simply remembering a complex passphrase, the trick allows anyone to essentially hold millions of dollars worth of digital cash in their brain alone, with no need to keep any records on a computer.
It turns out, however, that your mind is a surprisingly vulnerable place to put the key to your crypto-liquid assets. And now one hacker is releasing the brain-thieving software to prove it. Next month at the hacker conference DefCon, security Ryan Castellucci plans to release a piece of software he calls Brainflayer, designed to crack bitcoin brain wallets and let any hacker suck out the digital cash stored in them. Pills, thrills and polymer gels: what's the future for male contraception? There are, despite an ancient and colourful history, only three forms of male contraception: condoms, withdrawal and vasectomy.
The first condoms were used by Pasiphae, wife of King Minos of Crete, who used a goat’s bladder in her vagina to protect against his sperm, which was said to contain scorpions and serpents that killed his mistresses. The withdrawal method got bad press in the bible when Onan withdrew and spilt his seed rather than impregnate his widowed sister-in-law, Tamar.
God was very displeased with this contraceptive method and killed him. More Consensus on Coffee’s Benefits Than You Might Think. Rounding out concerns about the effect of coffee on your heart, another meta-analysis examined how drinking coffee might be associated with heart failure.
Again, moderate consumption was associated with a lower risk, with the lowest risk among those who consumed four servings a day. Consumption had to get up to about 10 cups a day before any bad associations were seen. No one is suggesting you drink more coffee for your health. But drinking moderate amounts of coffee is linked to lower rates of pretty much all cardiovascular disease, contrary to what many might have heard about the dangers of coffee or caffeine.
Chemistry set pencils can turn life-saving tests into child’s play. This piece was first published on The Conversation If you’ve ever sat opposite a doctor and wondered what she was scribbling on her notepad, the answer may soon not only be medical notes on your condition, but real-time chemical preparations for an instant diagnostic test.
Thanks to the work of a team of researchers from California Polytechnic State University, recently published in the journal Lab on a Chip, chemicals formed into pencils can be made to react with one another by simply drawing with them on paper. The team may have taken inspiration from colouring books for their take on a chemical toolkit, but their approach could make carrying out simple but common diagnostic tests based on chemical reactions – for example diabetes, HIV, or tests for environmental pollutants – much easier.

How cannabis was used to shrink one of the most aggressive brain cancers. Widely proscribed around the world for its recreational uses, cannabis is being used in a number of different therapeutic ways to bring relief for severe medical conditions.
Products using cannabinoids, the active components of the cannabis plant, have been licensed for medical use. Sativex, for example, which contains an equal mixture of the cannabinoids tetrahydrocannabinol (THC) and cannabidiol (CBD), is already licenced as a mouth spray for multiple sclerosis and in the US, dronabinol and nabilone are commercially available for treating cancer-related side effects. Now, in a study published in Molecular Cancer Therapeutics, we’ve also shown that cannabinoids could play a role in treating one of the most aggressive cancers in adults. There are more than 85 cannabinoids, which are known to bind to unique receptors in cells and which receive outside chemical signals. Woman gives birth after womb transplant, in medical first.

The 36-year-old mother received a uterus from a close family friend last year. Her baby boy was born prematurely but healthy last month, and mother and child are now at home and doing well. Is Breakfast Overrated? Photo For years, we’ve heard that breakfast is the most important meal of the day.
But scientific support for that idea has been surprisingly meager, and a spate of new research at several different universities — published in multiple articles in the August issue of The American Journal of Clinical Nutrition — could change the way we think about early-hours eating. The largest and most provocative of the studies focused on whether breakfast plays a role in weight loss. Researchers at the University of Alabama at Birmingham and other institutions recruited nearly 300 volunteers who were trying to lose weight. They randomly assigned subjects to either skip breakfast, always eat the meal or continue with their current dietary habits. Relax, UK – We're Not All Going to Die of Ebola. Some of the panicky headlines you may have read recently (Background image via) The latest Ebola outbreak has been ongoing for several months, killing over 600 West Africans.
However, it hasn’t been widely reported until now for two reasons: foreign reporting is becoming increasingly non-existent, and no Westerners had died yet, so nobody really cared. Two American casualties later and suddenly the British Foreign Secretary is raving about threats to national security – threats he was presumably oblivious to until he saw them in the New York Times.
Cyclists breathe easier on their own paths. June 27, 2014 — Boston has installed more than 50 miles of bike lanes since 2007, and the number of pedal-powered commuters in the city, while only 2.1%, is more than three times the national average.
To help urban planners continue to improve bike friendliness, researchers at Harvard School of Public Health (HSPH) set out to determine the types of lanes that expose cyclists to the smallest amount of vehicle pollution. The researchers attached a mobile monitoring unit to the back of a bicycle and hit the road to sample two types of pollutants from vehicular exhaust—black carbon and nitrogen dioxide—known to increase the risk of asthma, heart disorders, and other health problems. They traveled five common bicycling routes in the city during both morning and evening commutes, to compare bike paths, which are separated from the road, and bike lanes, which run adjacent to traffic.

An untreatable strain of the sexually transmitted disease gonorrhoea, resistant to all existing antibiotics, has been identified in Japan. The news follows warnings last week from the US Centers for Disease Control that it is only a matter of time before invincible strains of Neisseria gonorrhoea emerge in the US. The Japanese superbug, called H041, was isolated by Magnus Unemo at the Örebro University Hospital in Sweden, and reported this week at the International Society for Sexually Transmitted Disease Research meeting in Quebec, Canada.
