upstart writes:Planting Undetectable Backdoors in Machine Learning Models:These days the computational resources to train machine learning models can be quite large and more places are outsourcing model training and development to machine-learning-as-a-service (MLaaS) platforms such as Amazon Sagemaker and Microsoft Azure. With shades of a Ken Thompson speech from almost 40 years ago, you can test whether your new model works as you expect by throwing test data at it, but how do you know you can trust it, that it won't act in a malicious manner using some built-in backdoor? Researchers demonstrate that it is possible to plant undetectable backdoors into machine learning models. From the paper abstract:

Plattsburgh, in upstate New York, had some of the cheapest electricity rates in the country and crypto miners beat a path to their town to set up shop. In 2018 the town was receiving a major crypto mining application every week.

Taking a page from Elon Musk's SpaceX construction project in Boca Chica (Texas), the state of Maine's largest city (Portland) will be using SPMTs (Self-Propelled Mobile Transports) this coming weekend.It all starts at 7 PM (EDT) on Friday April 22 and continuing through 11 AM on Monday April 25, 2022. "It" is the replacement of a bridge on one of the busiest roads in the state: I-295. The whole highway will be closed, the existing overpass will be demolished, the rubble will be removed, and the previously-constructed replacement overpass will take a ride on the SPMTs to its new home... and you can watch it all happen on-line!The $20.8 million project has a web site: https://verandaplan.org/Linking to active content on their site is non-trivial, but try: https://verandaplan.org/livestream.

upstart writes:mRNA quality control identified as novel drug target for Alzheimer's and related dementias:Alzheimer's disease and similar disorders are often marked by the presence of pathological forms of proteins that cause neurons to die. Besides the amyloid beta proteins, which have received a lot of attention, there are also the tau proteins. Researchers from The University of Texas Health Science Center at San Antonio discovered a new mechanism whereby pathological forms of tau proteins cause cell death, which they believe can be treated with drugs.These proteins are created from messenger RNA (mRNA) that carry nonsense mutations. Clearing out these aberrant mRNAs occurs through a process called nonsense-mediated mRNA decay (NMD). The researchers noticed that pathological tau protein buildup was associated with disruptions in the NMD process. Instead of trying to figure out how to clear out the proteins, they think they can attack the cause of the NMD disruptions.

upstart writes:Rotating blue laser light reveals unimagined dynamics in living cells:University of Freiburg scientists have employed a microscopy technique known as rotating coherent scattering (ROCS) to resolve cellular-level detail without the need to rely on fluorescence imaging. This means they can make "movies" to study the dynamics of cells because they take images at 100 frames per second. It uses a rapidly rotating blue laser beam, causing lightwaves to scatter at the structures of cells to generate images. They use blue laser light because objects as small as cells and viruses scatter much more light in the blue than in the red, allowing them to get "brighter" pictures. The laser is also directed in at an oblique angle to increase the contrast of the image, much as how you'd look for smudges on surfaces by looking at light reflected at low angles.

hubie writes:The most complicated and expensive part of the supply chain is the last-mile delivery, where the costs can account for up to 28% of the total transportation cost and is projected to increase. The two main issues driving these costs will be the continual rise of e-commerce as well as rapid global urbanization, so there is a need for ways to optimize the delivery process to reduce costs. Urbanization leads to continued growth of traffic, which leads to transportation delays, higher fuel costs, and larger environmental impacts. These factors have led companies to consider deliveries by drone, but drones have limited battery capacities. Instead of looking at company delivery trucks as mobile charging stations from which to launch drones, a group of researchers considered utilizing public transportation vehicles to serve that purpose.The idea of letting drones recharge or hitch rides on buses and trams to conserve energy was first introduced by Stanford researchers. The researchers in this work extended that idea to using multiple drones and multiple warehouses operating around the actual transportation nodes of a city (Bremen, Germany) and found that this is an attractive and viable approach that can be implemented in the real world.Journal Reference:

hubie writes:The Central Valley of California makes up only 1% of U.S. farmland, but produces 40% of the nation's produce despite only receiving 5 to 10 inches (12 to 25 centimeters) of rainfall a year. That kind of productivity is due to massive pumping of groundwater for irrigation. After decades of pumping, parts of California are literally sinking and water is getting harder to get at (wells in the Tulare Basin have to be drilled a kilometer deep).Groundwater in this region comes from two sources that are separated by a dense layer of clay. The water on top of the clay resides in loose soil and this water gets replenished with rainfall and snowmelt runoff. The water below the clay is the aquifer and this is not replenished. A major problem is that nobody knows where the pumped water is being pulled from, nor how much of it remains.A research team from NASA's Jet Propulsion Laboratory and the U.S. Department of Energy's Lawrence Berkeley Laboratory came up with a new method to monitor changes between the two water sources.
