A decade after wisps of anthrax sent through the mail killed 5 people, sickened 17 others and terrorized the nation, biologists and chemists still disagree on whether federal investigators got the right man and whether the F.B.I.’s long inquiry brushed aside important clues. Now, three scientists argue that distinctive chemicals found in the dried anthrax spores — including the unexpected presence of tin — point to a high degree of manufacturing skill, contrary to federal reassurances that the attack germs were unsophisticated. The scientists make their case in a coming issue of the Journal of Bioterrorism & Biodefense. F.B.I. documents reviewed by The New York Times ...

"Don't worry, everything will be fine," says the brain One reason optimists retain a positive outlook even in the face of evidence to the contrary has been discovered, say researchers. A study, published in Nature Neuroscience, suggests the brain is very good at processing good news about the future. However, in some people, anything negative is practically ignored - with them retaining a positive world view. The authors said optimism did have important health benefits. Scientists at University College London said about 80% of people were optimists, even if they would not label themselves as such. They rated 14 people for their level of optimism and tested them in a ...

WASHINGTON, Oct. 9 (Xinhua) -- U.S. researchers have found a way to block, in an animal model, the damaging inflammation that contributes to many disease conditions. In their report receiving early online publication Sunday in Nature Biotechnology, researchers describe using small interfering RNA technology to silence the biochemical signals that attract a particular group of inflammatory cells to areas of tissue damage. "The white blood cells known as monocytes play a critical role in the early stages of the immune response," says Matthias Nahrendorf, of the Massachusetts General Hospital (MGH) Center for Systems Biology, the paper's senior author. "We now know there ...
UV risk grows in northern latitudes with growing Arctic ozone hole

The ozone loss over the Arctic was so severe this year that for the first time a 'hole' in the ozone layer, similar to the one over the Antarctic, appeared. At a level of around 13 miles above the ground, 80 per cent of the ozone was lost, potentially exposing people on Earth's surface to harmful ultraviolet-B rays from the sun, which can cause sunburn and skin cancer. The loss happened not because of increased use of ozone-destroying chemicals - now banned, and rarely used - but because cold high-altitude weather made the existing chemicals 'more active'. An ozone hole five times the size of California opened over the Arctic this spring, matching ozone loss over ...

Today Ford Motor Company and the United Auto Workers agreed to a new four-year contract that will add $6.2 billion of investment to U.S. factories, and a close look at the details reveals some news about the upcoming 2013 Shelby GT500. There has been much speculation about what engine will be used in the next generation Shelby. Back in March Car and Driver reported that the new GT500 would pack more than 600 horsepower to one-up the new Chevrolet Camaro ZL1. At the time it was thought the increase in horsepower would come via an increase in displacement to 5.8-liters and that the Eaton M112 supercharger would be replaced with the newer and larger TVS2300 unit. A few months later a batch of ...

Cannabis oil is a highly efficient natural cancer cure Monday, October 03, 2011 by: Michelle Bosmier See all articles by this author Email this author 4136 Share (NaturalNews) Ever since the mid 70s, medical scientists have been well aware of the beneficial effects of cannabinoid compounds over cancerous cells. Thanks to modern science, over a dozen studies conducted during recent years have been able to partially reveal just how it works. Yet cannabis is still not endorsed by pharmaceutical companies as a cancer cure, and since it is not promoted through mainstream channels, very few people are aware of its benefits. Consequently, it is not sought after as an alternative to ...

When Russian scientists sent a robot into the Chernobyl Nuclear Power Plant in 2007, the last thing they expected to find was life. Inside the most radioactive areas of the breached core was a group of common fungi collectively referred to as "black mold" growing on the reactor walls. These molds were growing in one of the most hostile environments on the planet, with radiation levels high enough to give a lethal dose in minutes. But these fungi weren't just growing, they were thriving. A researcher at New York's Albert Einstein College of Medicine, Arturo Casadevall, investigated these resistant molds and helped to identify several distinct species. They all shared ...
Women found to be the tougher sex

While women have for centuries been labelled as the weaker sex, new research suggests the truth is quite the opposite. According to a study, the fairer sex is genetically programmed to better resist infections and cancer, and also have a back-up system for fighting disease. The discovery sheds light on why members of the so-called stronger sex succumb to "man-flu". Their immune systems are no match for those of wives and girlfriends because of the female X-chromosome, scientists believe. The reason why women are more robust appears to be microRNAs - short strands of RNA encoded on the chromosome. RNA is a genetic cousin of DNA and can have important biological effects. ...
How immune cells lead to cancer

The study prompts a re-think of cancer therapies that aim at boosting the immune system. Scientists at A*STAR’s Singapore Immunology Network (SIgN) have shown for the first time that PMN-MDSC body’s immune system to combat cancer, a type of immune cell in the body that suppresses the immune response, can actually accelerate the growth and spread of cancerous tumours directly. This finding explains how inflammation, the body's natural defence mechanism when a tissue or an organ becomes affected, is linked to cancer progression. It also highlights the need for a careful reassessment of current cancer therapies that target the body’s immune system to combat cancer. Using a ...
Antimagnet' joins list of invisibility approaches

Researchers have designed a "cloak" that is invisible to magnetic fields both coming in and coming out. The idea of blocking magnetic fields has been proposed before, but the new design, in the New Journal of Physics, could even hide magnetic materials. It could thus find application in security or medical contexts, such as those surrounding MRI scans. The approach uses superconductor layers and the "metamaterials" familiar from recent invisibility cloak research. Metamaterials are artificially designed materials designed to guide electromagnetic waves - like light or magnetic fields - in a way that natural materials do not. Much research in recent years has ...

Greenbelt - Scientists are monitoring a sunspot that produced an X1.9-category solar storm that was unleashed over the weekend and could be headed towards Earth. Sunspot 1302 is so strong that it has been detected shortwave radio on this planet. Digital Journal has reported in the past on intense solar storms, and so far nothing catastrophic has occurred. The worst thing that has transpired thus far has been loss of radio signals in some parts of the United States. On Monday, NASA issued a news release that updated us on a strong X1.9-category solar storm that erupted from active region (sunspot) 1302 Saturday morning that was recorded by the space administration’s Solar Dynamics ...
Virus kills all grades of breast cancer ‘within 7 days’ in lab experiment

Scientists at the Penn State College of Medicine said this week they have discovered a virus that is capable of killing all grades of breast cancer "within seven days" of first introduction in a laboratory setting. The virus, known as adeno-associated virus type 2 (AAV2), is naturally occurring and carried by up to 80 percent of humans, but it does not cause any disease. Researchers learned of its cancer-killing properties in 2005, after Penn State scientists observed it killing cervical cancer cells. They also found that women who carried the AAV2 virus and human papillomavirus (HPV), which causes cervical cancer, had a lower propensity to develop cervical cancer. When ...

Protein 'Switches' Could Turn Cancer Cells Into Tiny Chemotherapy Factories
Post Date: 2011-09-25 05:53:01 by Tatarewicz
0 Comments
ScienceDaily (Sep. 24, 2011) — Johns Hopkins researchers have devised a protein "switch" that instructs cancer cells to produce their own anti-cancer medication. In lab tests, the researchers showed that these switches, working from inside the cells, can activate a powerful cell-killing drug when the device detects a marker linked to cancer. The goal, the scientists said, is to deploy a new type of weapon that causes cancer cells to self-destruct while sparing healthy tissue. This new cancer-fighting strategy and promising early lab test results were reported this week in the online early edition of Proceedings of the National Academy of Sciences. Although the switches have ...

The world’s first 'printed' car has finally rolled off the printing press. The 'Urbee' was made using a special printer which built up layer upon layer of bodywork - almost as if the car was 'painted' into existence, except using layers of ultra-thin composite that are slowly 'fused' into a solid. But unlike most 'innovations' in cars, this one won't break down after 5 years - Urbee is built to last 30. Project leader Jim Kor, told MailOnline today: 'For us, this unveiling was quite a milestone.

-PASADENA, Calif. (AP) — Elizabeth Cochran was sitting in her office when her computer suddenly sounded an alarm. Beep. Beep. Beep. A map of California on her screen lit up with a red dot, signaling an earthquake had struck. A clock next to the map counted down the seconds until shock waves fanning out from the epicenter north of Los Angeles reached her location in Pasadena: 5-4-3-2-1. Right on cue, Cochran felt her chair quiver ever so slightly from a magnitude-4.2 that rumbled through Southern California on Sept. 1. "If I hadn't known it was an earthquake, I would have thought it was a truck going by," she said. After years of lagging behind Japan, Mexico and other ...

Particle physicists detect neutrinos travelling faster than light, a feat forbidden by Einstein's theory of special relativity Subatomic Neutrino Tracks Neutrinos, like the ones above, have been detected travelling faster than light, say particle physicists. It is a concept that forms a cornerstone of our understanding of the universe and the concept of time – nothing can travel faster than the speed of light. But now it seems that researchers working in one of the world's largest physics laboratories, under a mountain in central Italy, have recorded particles travelling at a speed that is supposedly forbidden by Einstein's theory of special relativity. Scientists at ...

CERN scientists 'break the speed of light' Scientists said on Thursday they recorded particles travelling faster than light - a finding that could overturn one of Einstein's fundamental laws of the universe. Antonio Ereditato, spokesman for the international group of researchers, said that measurements taken over three years showed neutrinos pumped from CERN near Geneva to Gran Sasso in Italy had arrived 60 nanoseconds quicker than light would have done. "We have high confidence in our results. We have checked and rechecked for anything that could have distorted our measurements but we found nothing," he said. "We now want colleagues to check them ...
