CBS News Hurricane Harvey left hundreds of communities in southeast Texas without safe drinking water. At least 45 water systems are shut down, and 171 areas have issued boil water notices. But Houston is not on that list, despite significant flooding at one of its water plants. “The filters are the life blood of the plant. If you lose filtration, there’s nothing you can do,” said … Continue reading Harvey floods left Houston water plant hours away from failure

The increasingly menacing storm would continue churning west in the Atlantic Ocean on Tuesday, and meteorologists say Puerto Rico and other Caribbean islands could begin to see its wrath by the … Continue reading Hurricane Irma strengthens into category 5 storm
The FDA has just granted approval to Second Sight Medical Products to embark on a human clinical study of its newest visual prosthesis system. Known as Orion, the device is a newer iteration of the Sylmar, California-based company’s successful Argus II retinal implant product.
The Argus II gained approval in 2013, and it restores certain visual capabilities to people who have blindness that is caused by the inherited retinal degenerative illness Retinitis Pigmentosa (RP). The Orion expands on this ability, boasting the potential to help treat nearly every form of profound blindness.
The FDA’s conditional approval will allow two American sites to test the device on a handful of patients, but additional device testing will be required to gain full approval. The company also has to address some outstanding questions that the FDA has about the product. The clinical trial sites have been identified as The University of California at Los Angeles and Baylor College of Medicine in Houston.

Gold nanoparticles brighten the fluorescent dyes researchers use to highlight and study proteins, bacteria and other cells, but the nanoparticles also introduce an artifact that makes the dye appear removed from the target it’s illuminating.
When researchers want to understand how proteins interact with each other, how bacteria function or how cells grow and divide, they often use fluorescent dyes. This microscopy approach can be further enhanced with nanoparticles. But an artifact introduced by the nanoparticles makes the dye appear in the microscope as far as 100 nanometers removed from the protein or bacteria to which it is directly bound.
This “scooching effect” presents a problem: 100 nanometers may seem like an infinitesimal measurement, but if a protein is itself only a nanometer in length, a researcher might not be able to tell whether a protein is interacting with another protein or just gazing at it from the equivalent of the opposite end of a football field.

Pete Farley Medical Express UC San Francisco scientists have developed an imaging tool that could soon allow doctors to locate and visualize bacterial infections in the body and to rule out other common causes of inflammation, such as autoimmune reactions. On August 11, 2017 in Scientific Reports, the UCSF research team reported that scans made with the imaging technique known as PET (positron emission tomography) effectively … Continue reading New tool may allow doctors to ‘see’ bacterial infection in the body
AP via ABC News The U.S. Defense Department is making another multimillion-dollar investment in high-energy lasers that have the potential to destroy enemy drones and mortars, disrupt communication systems and provide military forces with other portable, less costly options on the battlefield. U.S. Sen. Martin Heinrich, a member of the Senate Armed Services Committee and longtime supporter of directed energy research, announced the $17 million investment … Continue reading ‘Sci-fi to real life’: US invests $17 million in laser tech
Apple is one of the largest tech companies in the United States that have been involved in user spying scandals, with many accusing the firm of working with the government on snooping on customers and providing law enforcement with access to their data.
Cupertino, on the other hand, has actually claimed to be doing otherwise, fighting against the government on several occasions, including in early 2016 when it refused to hack a locked iPhone that was allegedly used by one of the San Bernardino terrorists.
