Killer parasites' genes decoded

July 31st, 2009 No comments

BBC NEWS | Health | Killer parasites’ genes decoded.

Scientists have decoded the genetic blueprint of two parasitic flatworms responsible for thousands of deaths worldwide every year.

Researchers working on the genetic blueprint of S. masoni, the most widespread of the schistosomiasis parasites, found that it was made up of 11,809 genes – about 10 times the size of the malaria parasite genome.

In particular, they identified a large number of genes which produce enzymes that break down proteins, giving the parasite its ability bore through tissue.

Subsequent analysis revealed 120 enzymes that could potentially be targeted with drugs to disrupt the worm’s metabolism.

The researchers also identified 66 drugs already on the market which might also be effective against schistosomiasis.

Exposed: the PC repair shops that rifle through your photos and passwords

PC Pro: News: Exposed: the PC repair shops that rifle through your photos and passwords.

The exercise was simple. Create a simple fault on a laptop, load it with spy software, take it into several repair shops, then sit back and see what happened. Would they arrive at the same diagnosis and charge us a fair price to fix it?

First, Sky News engineers installed professional spy software on a new laptop. Spector Pro was programmed to load on start-up and silently record every ‘event’ that took place. If the mouse was moved, a folder opened or a file looked at, we would know about it. Every event would also trigger a screen snapshot to be taken.

We also installed Digiwatcher. This devious little tool auto-runs on start-up and quietly tells any connected webcam to secretly film whoever is at the machine. The process is invisible and the video file is hidden on the hard drive and password protected.

To create the fault, we simply loosened one of the memory chips so Windows wouldn’t load. To get things working again, one needs only push the chip back into the slot and reboot the machine. Any half-way competent engineers should fix it in minutes.

Laptop Revival in Hammersmith initially offered us a free diagnosis when we dropped our laptop off. Yet the spy software later revealed something extraordinary. The webcam shows that almost immediately the technician discovers our loose memory chip and clicks it back into position [based on recorded boot and shut down times]. The machine is rebooted and the problem solved.

Yet he then begins browsing through our hard drive. A folder marked ‘Private’ is opened and he flicks through our researcher’s holiday photographs, including intimate snaps of her wearing a bikini. He stares at picture after picture, stopping only to show them to colleagues.

He then picks up the phone and calls our researcher. He tells her our motherboard is faulty and will need to be replaced. Usually it costs £130 but he’ll do it for £100. We tell him we’ll think about it and call him tomorrow.

After more snooping, he logs off. But a few hours later, another technician boots our machine. He also begins searching our hard drive until he finds log-in details for our Facebook and Hotmail accounts. With a cackle he removes a memory stick from around his neck, plugs it in and then copies them across.

He also discovers our holiday photos and copies those of our researcher in her bikini.

Most worryingly, when he discovers log-in details for our online bank account, he logs onto the bank’s website and attempts to break into the account. He only fails because the details we created were false.

There were also difficulties with PC World in Brentford. The technician triumphantly diagnosed a faulty motherboard and insisted we needed a new one. We were told unless we paid £230 in advance, we couldn’t have it repaired. We agreed. But when we collected the laptop and got it home, we discovered only a memory chip had been replaced and not the motherboard.

at Evnova Computers in Barbican the loose memory chip was also spotted and fixed. But the company also told us we needed a new motherboard. We declined the offer and collected our laptop. When we examined it, we discovered technicians had soldered the memory bus pins together to recreate the original fault.

Students Embed Stem Cells Into Sutures for Tendon Repair

July 31st, 2009 No comments

DailyTech – Students Embed Stem Cells Into Sutures for Tendon Repair.

Biomedical engineering students from Johns Hopkins have demonstrated a way to use stem cells from a patient to help repair serious orthopedic injuries such as ruptured tendons. The students demonstrated a method of embedding the patient’s own stem cells into a surgical thread that the surgeon uses to repair torn tendons.

The new process doesn’t change or impact the way that surgeons repair the injury. Currently the new process is undergoing animal trials and will hopefully make it to human trials in about five years. The new process has great promise for speeding healing from serious injuries.

Matt Rubashkin, the student team leader said, “Using sutures that carry stems cells to the injury site would not change the way surgeons repair the injury. But we believe the stem cells will significantly speed up and improve the healing process. And because the stem cells will come from the patient, there should be no rejection problems.”

DailyTech – ESA’s Venus Express Beams Back Evidence of a Wet Past.

Venus may have looked like Earth, just not for very long.

After a November 2005 launch, the European Space Agency’s scientific satellite, Venus Express, reached the planet in April of the following year and settled into its working orbit shortly after in May. Since then, the orbiter has been beaming back many kinds of data about the cloud-covered planet, enabling researchers to better understand its lifecycle and past.

Venus Express left Earth with seven instruments bent on unmasking Venus and revealing to us her secrets. All seven instruments were derived from the previous projects Mars Express and Rosette. ASPERA-4 analyses neutral and ionized plasma; MAG takes magnetic field measurements; PFS uses infrared Fourier spectroscopy to take vertical pictures of the atmosphere; SPICAV also uses spectroscopy to measure atmospheric content by using sun or starlight occultation; VeRa uses radio sounding to measure atmosphere; VIRTIS maps the atmosphere and surface of the planet via spectography; and VMC images in ultraviolet and visible light ranges.

Wireless power system shown off

July 31st, 2009 No comments

BBC NEWS | Technology | Wireless power system shown off.

A system that can deliver power to devices without the need for wires has been shown off at a hi-tech conference.

The technique exploits simple physics and can be used to charge a range of electronic devices over many metres.

Eric Giler, chief executive of US firm Witricity, showed mobile phones and televisions charging wirelessly at the TED Global conference in Oxford.

He said the system could replace the miles of expensive power cables and billions of disposable batteries.

“There is something like 40 billion disposable batteries built every year for power that, generally speaking, is used within a few inches or feet of where there is very inexpensive power,” he said.

Hubble pictures Jupiter's 'scar'

July 31st, 2009 No comments

BBC NEWS | Science & Environment | Hubble pictures Jupiter’s ‘scar’.

Hubble has trained its new camera on the atmospheric disturbance on Jupiter believed to have been caused by a comet or asteroid impact.

The telescope used the Wide Field Camera 3 fitted on the recent shuttle servicing mission to capture ultra-sharp visible-light images of the scar.

The dark spot near the gas giant’s southern pole was noticed first by an amateur Australian astronomer.

Google’s done it again

July 19th, 2009 No comments

So much for google’s “do no evil” motto.. (I guess supporting the censorship of human rights and civilian massacres seems alright to them), they’ve done it again, screwing up its customers. I loaded my Picasa site today, it was empty. No notice, no instructions, no warnings, no nothing.

If you have a paying Picasa account and have a single picture you think might be against what they deem innapropiate in line with their terms of service, you might as well take it down and think it twice before renewal. They removed my entire 35k pictures gallery, which included only art (screenshots) and personal photo albums. It’s all gone.

- You’ll get no warning
- They’ll delete everything, even personal pictures
- You can’t contact them, at all. I mean it, try a search “how to contact google”
- If you paid for storage you are not getting your money back, even if you were on their $500 plan
- You won’t be able to upload to your account again, even if your paid storage plan is still active.

So yeah, they won’t be seeing my few $ upon the next renewal.

Study Shows Drug Rapamycin Extends Lifespan of Mammals

July 15th, 2009 No comments

DailyTech – Study Shows Drug Rapamycin Extends Lifespan of Mammals.

Researchers have discovered the first drug that has been proven to extend the lifespan of mammals when taken late in life. The drug is called rapamycin and is derived from bacteria that lives in the soil on the remote and legendary Easter Island most well-known for its gigantic moai statues.

Rapamycin is already used to treat disease in humans and is an antifungal compound that is approved by the FDA as an immunosuppressive therapy to prevent rejection in organ transplant patients. The drug is also undergoing clinical trials at this time as an anti-cancer drug. Previous studies had proven that the drug was capable of extending the lifespan of invertebrates.

The new study gave the drug to mice starting at 20 months of age, the equivalent of 60 human years. During the study, the researchers found that the drug was able to extend the life of male mice by 9% and by 13% in female mice.

Lawyers plan class-action to reclaim $100M+ RIAA stole

July 14th, 2009 No comments

Lawyers plan class-action to reclaim “$100M+” RIAA “stole” – Ars Technica.

The recording industry has spent (and continues to spend) millions of dollars on its litigation campaign against accused file-swappers, but if two lawyers have their way, the RIAA will have to pay all the money back. Not content simply to defend Jammie Thomas-Rasset in her high-profile retrial next week in Minnesota, lawyer Kiwi Camara is joining forces with Harvard Law professor Charles Nesson to file a class-action lawsuit against the recording industry later this summer.

The goal is nothing less than to force the industry to pay back the alleged “$100+ million” it has collected over the last few years. Perhaps the RIAA had good reason not to send those settlement letters to Harvard for so long.

Scientists Use Sudoku to Speed Genome Sequencing

July 7th, 2009 No comments

DailyTech – Scientists Use Sudoku to Speed Genome Sequencing.

Scientists thing the new method can save millions in sequencing costs

Scientists at the Cold Spring Harbor Laboratory (CSHL) have discovered a new method of pooling a multitude of DNA samples for sequencing. The new method is being called DNA Sudoku because it uses a method similar to the math game to greatly increase the speed at which DNA can be sequenced.

The researchers report that DNA Sudoku method allows for tens of thousands of DNA samples, short combinations of polynucleotides with A, T, G, and C bases, to be combined and sequenced.  The simultaneous sequencing is done by looking at the letter order and comparing it to the correct order of the known human genome using an algorithm that resembles those used to solve Soduku puzzles.

The ability to do all the sequencing at once is a massive improvement over past methods that allowed only a single DNA sample to be sequenced at a time. It is also an improvement on current techniques that can ideally only combine hundreds of samples.
