7:30 PM | Ask a Geek: How Can I Permanently Delete My Computer Files?

Wiped Clean Thilo RothackerMake sure nobody will ever see your classified documents. Before you sell, donate, or recycle your old computer, beware: You may be handing personal information to strangers. Simply restoring the operating system to factory settings does not delete all data and neither does formatting the hard drive before reinstalling the OS. To really wipe a drive clean, users will need to run secure-erase software. For Windows, the best bet is the command-line utility SDelete […]

Supreme Court rules natural genes not patentable

The Supreme Court ruled unanimously on Thursday, June 13th, that Myriad Genomics Inc. may not retain exclusive rights to the use of DNA sequence information for breast cancer associated genes BRCA1 and BRCA2, stating that Myriad had not created anything new in identifying the genes.

Hey boy, you really activate my ventral midbrain.

By Brooke Napier Scientists at CalTech simultaneously found a way to stimulate your midbrain without invasive methods (ie: opening up your skull) and make you find them attractive. Chib, et al. reported in Translational Psychiatry that by using their newly designed noninvasive method called transcranial direct current stimulation (tDCS) on the prefrontal cortex they were able to activate the interconnected midbrain. Why would you want to activate the midbrain? The ventral midbrain (also known […]

Autoimmune disease as a risk factor for mood disorder?

Autoimmunity, the process by which the immune system fails to recognise self as self and subsequently targets those self tissues and cells, is something talked about quite a lot on this blog with autism specifically in mind. Part of the very wide and diverse immune-related features which have been discussed with at least some of the autisms in mind, it's not yet altogether clear exactly how and why autoimmunity is linked to behaviour but the association is an interesting one.Sally? @ […]

New Silicon Wafer Production Method to Make Solar Cells Cheaper

A team of researchers from the Nanoengineering Research Centre (CRNE) and the Department of Electronic Engineering at the Universitat Politècnica de Catalunya—BarcelonaTech (UPC) has found a way to manufacture crystalline silicon materials cheaper and faster. The results of their research have recently been published online in Applied Physics Letters. This thin crystalline silicon wafer production method can be used to fabricate the latest generation of solar cells. Read more »

After the Devastation: Is There Hope For Large Wildlife Conservation Following Mountaintop Removal?

By David Jachowski Photo by biotour13 via Flicker and a Creative Commons License  What if the future of biodiversity conservation isn't in National Parks and protected areas, but in abandoned places? The played-out farm fields or remains after mountaintop removal for a seam of coal. Those overused and now typically overlooked parcels of land that saw a brief boom in
