Where the Web became harmful

June 5th, 2009 No comments

List of search terms what can give you most harmful results from.

“If you’re hacking for profit, the best way to make money is with the largest pool of potential victims,” he said. “The biggest crowd is going to be around these trends.”

These are the search terms put you at the most risk from hackers:

  • Word Unscrambler
  • Lyrics
  • Printable Fill in Puzzles
  • Free Ringtones
  • Solitaire
  • Free Music
  • Free Music Downloands
  • MySpace

Top 10 Malware Sites what can make your computer or your bank account ill. Google not only scan web for all sorts of textual information. It can recognize sites with a content of some specific sort.

Our automated systems found more than 4,000 different sites that appeared to be set up for distributing malware by massively compromising popular web sites. Of these domains more than 1,400 were hosted in the .cn TLD. Several contained plays on the name of Google such as goooogleadsence.biz, etc.

Other malware researchers reported widespread compromises pointing to the domains gumblar.cn and martuz.cn, both of which made it on our top-10 list. For gumblar, we saw about 60,000 compromised sites; Martuz peaked at slightly over 35,000 sites. Beladen.net was also reported to be part of a mass compromise, but made it only to position 124 on the list with about 3,500 compromised sites.

Provocation as an art

May 29th, 2009 No comments

The Dutch “artist” who in 2004 turned her pussy into a handbag under the performance art title “My dearest cat Pinkeltje (2004)” has published personal details of those who emailed her expressing their disgust.

Katinka Simonse, aka Tinkebell, copped a veritable shitstorm of e-abuse for the feline fashion accessory stunt (pictured), and she and fellow artist Coralie Vogelaar decided to track down the senders, sniff out their intimate online secrets and present the whole thing for public consumption.

Everything is a black holes (no pun intended)

May 28th, 2009 No comments

In trying to understand how gravity behaves on the quantum scale, physicists have developed a model that has an interesting implication: mini black holes could be everywhere, and all particles might be made of various forms of black holes.

As the physicists explain, gravity is considered an astronomical-scale force; its effects on smaller scales seem to be virtually nonexistent. However, as the scientists write, “it has often been assumed that near the Planck scale, gravity would somehow assert itself and become comparable in strength to the other forces of nature, likely as a product of some grand unification picture.” Coyne and Cheng approach the problem of small-scale gravity by presenting a new model of black hole evaporation. As black holes lose energy, they slowly evaporate, shrinking in size down to the quantum scale – where they may be identical to elementary particles.

Speech and lang processing in the brain

May 28th, 2009 No comments

Current situation in the field of unified theory about how the brain processes speech and language.

both human and non-human primate studies have confirmed that speech, one important facet of language, is processed in the brain along two parallel pathways, each of which run from lower- to higher-functioning neural regions.

Then time of recovering from injure is matters

May 27th, 2009 No comments

Article on Physorg about what cutting age medical technology can give to athletes then they broke something and need to be repaired.

You stub your big toe and the pain has you hobbling for weeks. UNC point guard Ty Lawson jams his and two days later plays 36 minutes.

Tiger Woods injures the anterior cruciate ligament in his left knee and goes on to win five of his next six golf tournaments before deciding to have surgery. You injure your ACL and sit on the couch watching Woods.

Why is it that injuries that take the rest of us out of action for weeks, months or possibly forever, only bench elite athletes for a short time? Is their body makeup that superior? Do they have a heightened tolerance for pain? Do they have access to cures of modern medicine unavailable to the rest of us? Are they simply treated differently?

Daydreaming not a lost time

May 20th, 2009 No comments

The study, published in the Proceedings of the National Academy of Sciences, finds that activity in numerous brain regions increases when our minds wander. It also finds that brain areas associated with complex problem-solving – previously thought to go dormant when we daydream – are in fact highly active during these episodes.

“Mind wandering is typically associated with negative things like laziness or inattentiveness,” says lead author, Prof. Kalina Christoff, UBC Dept. of Psychology. “But this study shows our brains are very active when we daydream – much more active than when we focus on routine tasks.”

Five heresies of Freeman Dyson

May 16th, 2009 No comments

Lecture from one of famous mind of our time Freeman Dyson. It is about not what waiting us in the Future but what we can begin looking at today.
Main themes of this lecture is Climat management, rains in Sahara , Home Biotech, Nuclear Weapons.

Best quote about a place of computers in our life.

For better or for worse, in sickness or in health, till death do us part, humans and computers are now joined together more durably than husbands and wives.

Positive stereotype win the battle

May 5th, 2009 No comments

In a new study led by Robert J. Rydell, assistant professor in the Department of Psychological and Brain Sciences at Indiana University, focused on women and math ability.

Was shown that when aware of both a negative and positive stereotype related to performance, women will identify more closely with the positive stereotype, avoiding the harmful impact the negative stereotype unwittingly can have on their performance. Stereotype threat — where just the awareness of a stereotype can influence performance regardless of actual ability — has been demonstrated in many domains, from driving cars to cooking. In academics, high-stakes tests, such as college entrance exams, often ask test-takers to select demographic information, such as gender and level of education, before beginning the test.

Also interesting moment what words not the only way for people to become aware of stereotype situation.

Rydell said people become aware of stereotypes in different ways. For women, simply sitting between two men while taking a math test can activate the negative gender stereotype.

Potential fifth force of nature, outcome of LHC

May 1st, 2009 No comments

The Large Hadron Collider is an huge particle accelerator whose 27 kilometres tunnel beneath the Franco-Swiss border. A group of physicists at the University of Nevada, Reno has analyzed data from the accelerator that could ultimately prove or disprove the possibility of a fifth force of nature. Their refined analysis sets new limits on a hypothesized particle, the extra Z-boson, carving out the lower-energy part of the discovery reach of the LHC.

Andrei Derevianko, from the College of Science’s Department of Physics, who has conducted groundbreaking research to improve the time-telling capabilities of the world’s most accurate atomic clocks, is one of the principals behind what is believed to be the most accurate to-date low-energy determination of the strength of the electroweak coupling between atomic electrons and quarks of the nucleus.

We carry out high-precision calculation of parity violation in cesium atom, reducing theoretical uncertainty by a factor of two compared to previous evaluations. We combine previous measurements with our calculations and extract the weak charge of the 133Cs nucleus, Q_W = -73.16(29)_exp(20)_th. The result is in agreement with the Standard Model (SM) of elementary particles. This is the most accurate to-date test of the low-energy electroweak sector of the SM. In combination with the results of high-energy collider experiments, we confirm the energy-dependence (or “running”) of the electroweak force over an energy range spanning four orders of magnitude (from ~10 MeV to ~100 GeV). Additionally, our result places constraints on a variety of new physics scenarios beyond the SM. In particular, we increase the lower limit on the masses of extra $Z$-bosons predicted by models of grand unification and string theories.

To use a statistics you need to be reminded of it

April 27th, 2009 No comments

Overall, the researchers found that a predisposition to look at data statistically (either because of hint given by the experimenters, the nature of the data, or the nature of the individual’s experience) led to more statistical reasoning. In addition, people who had been trained in statistics — both formally and informally in very brief training sessions — were more likely to use statistical reasoning to solve problems.
