950 Pro review: Samsung’s first PCIe M.2 NVMe SSD is an absolute monster

(credit: Orestis Bastounis) The 950 Pro isn’t Samsung’s first consumer M.2 SSD, or even the company’s first PCIe M.2 drive. It is, however, Samsung’s first consumer M.2 and NVMe drive that uses the full performance of four PCIe 3.0 lanes. It is also an upgrade from its predecessor the SM951, in that it uses 3D V-NAND rather than planar NAND. Somewhat disappointingly, the 950 Pro comes in only two capacities for now: 256GB or 512GB, with a 1TB model promised for next year. Samsung is resolute in only producing single-sided M.2 devices to keep the drive’s thickness to a minimum, so the 1TB drive will have to wait until 48-layer 3rd-generation V-NAND is available. Thankfully, no 128GB model will be sold, indicating that 128GB SSDs may be on their way out. UK pricing is pegged at £150 for the 256GB model and £270 for 512GB; in the US, it’s $200 and $350, respectively. As always, expect some variation between retailers with these prices, and in these early days, prices may be slightly higher than what Samsung is quoting. We’re told that the 950 Pro will hit retailers today; we’ll update this story with some links when they first appear. Read 44 remaining paragraphs | Comments

3D-Printed Teeth Can Kill 99% of Dental Bacteria

An anonymous reader writes: A research group in the Netherlands has developed a new plastic resin that can destroy most dental bacteria when used for the creation of dental appliances via 3D-printing. The process involves embedding antimicrobial quaternary ammonium salts inside extant dental resin polymers. Since the salts are positively charged, these disrupt negatively-charged bacterial membranes. The process is also being mooted for use in the creation of knee arthroplasties, and in the manufacture of children’s toys and food packaging. Read more of this story at Slashdot.

How We Figure Out the Composition of a Substance by Hurling Neutrons at It

Archaeologists can figure out how old a substance is by radiocarbon dating, but to do that they need to know what the substance is—and that’s not always clear. Radioactive material comes to the rescue again! Read more…

How Neurosurgeons Can Now Look at Your Brain Through Your Eyes

For many years scientists have been trying to find a way to measure the pressure in a patient’s brain without having to drill a hole in the person’s skull. Although this remains the most reliable way to measure pressure in the brain it is invasive, expensive and comes with the risk of infection and bleeding. Read more…

In Nigeria, Solar-Powered Fridges at Outdoor Markets Save Food From Spoiling

In developing countries, an unbelievable 45% of food goes bad because of a lack of cold storage. It’s an especially big problem during transportation from farms to outdoor markets, where food sits in the scorching sun for hours on end. But one startup has a solution: solar-powered refrigeration stations that could save the livelihoods of half a billion farmers worldwide. Read more…

Drought Brings a 16th-Century Mexican Temple to the Surface Again

The ruins of the Temple of Santiago are not an easy destination to visit, or even have a look at. The walls of the once sacred building are usually hiding under water, but now drought lowered the river the temple has been hiding in, revealing a rather awesome sight. Read more…

How to Protect Yourself from the NSA If You Use 1024-bit DH Encryption

In a post on Wednesday, researchers Alex Halderman and Nadia Heninger presented compelling research suggesting that the NSA has developed the capability to decrypt a large number of HTTPS, SSH, and VPN connections using an attack on common implementations of the Diffie-Hellman key exchange algorithm with 1024-bit primes. Earlier in the year, they were part of a research group that published a study of the Logjam attack, which leveraged overlooked and outdated code to enforce “export-grade” (downgraded, 512-bit) parameters for Diffie-Hellman. By performing a cost analysis of the algorithm with stronger 1024-bit parameters and comparing that with what we know of the NSA “ black budget ” (and reading between the lines of several leaked documents about NSA interception capabilities) they concluded that it’s likely NSA has been breaking 1024-bit Diffie-Hellman for some time now.
