To work safely, self-driving cars must avoid obstacles -- including those just out of sight. And for this to happen, we need technology that sees better than humans can, says electrical engineer David Lindell. Buckle up for a quick, groundbreaking tech demo as Lindell explains the significant and versatile potential of a high-speed camera that can detect objects hidden around corners.

Recounting her story of finding opportunity and stability in the US, Elizabeth Camarillo Gutierrez examines the flaws in narratives that simplify and idealize the immigrant experience -- and shares hard-earned wisdom on the best way to help those around us. "Our world is one that flourishes when different voices come together," she says.

To combat COVID-19, countries have enforced city-wide shutdowns, stay-at-home orders and mask mandates -- but the reaction (and adherence) to these rules has differed markedly in the East and West. In conversation with TED's head of curation Helen Walters, writer and publisher Huang Hung sheds light on how Chinese and American cultural values shaped their responses to the outbreak -- and provides perspective on why everyone needs to come together to end the pandemic.

A measure now before Virginia's governor would let teachers bargain with local boards over wages and working conditions if a local board authorizes it.

It took a lot to drive Oklahoma teacher John Waldron from the classroom to the statehouse. And he's still angry.

The new curriculum would teach all students about tribes and Indian culture in North Dakota.

North Dakota lawmakers fended off an effort to ensure that the state's new standards, and any tests that might be used with them, won't mirror the common core.

North Dakota is the latest state to make a push for integrating Native American or other ethnic studies into school curricula.

Commissioner Wayne Lewis requested a list of the teachers who had taken sick days in the 10 districts where teacher absences caused work stoppages.

Here's a clue: the governor has said the teachers' unions need to be punched in the face.

Mary Jackson's story is among those depicted in the book "Hidden Figures," which focused on the lives of black women who worked as mathematicians and engineers for NASA during the Space Race. Before landing there, Jackson worked as a math teacher in Maryland.

Matthew Utterback, the superintendent of the North Clackamas district in Oregon, was named last week as the 2017 National Superintendent of the Year.

Kansas and Missouri are resuming their bitter Border War in football after the former Big 12 rivals agreed to a four-game series in which each school will play two home games beginning in September 2025. The fourth-longest rivalry in college football dates to 1891, but it has been on hiatus since Missouri departed for the Southeastern Conference. The schools recently announced a six-game series in men's basketball beginning with the upcoming season that includes two games on each campus and two in Kansas City, Missouri.

The NFL is indeed discussing the possibility of playing games on Saturdays in the event that college football doesn't proceed with a season from September through December. As one source with direct knowledge of the discussions tells PFT, however, the league's strong preference is for college football to happen, as scheduled. No college football season [more]

Hubbard was the AP Big 12 Offensive Player of the Year and finished eighth in the Heisman Trophy voting, the third-best finish for a Canadian player. It was the second-best single-season total in school history, trailing only Barry Sanders' 1988 Heisman season. Hubbard was the runner-up for the Cornish Trophy in 2019 after his redshirt freshman season.

NCAA President Mark Emmert says the coronavirus is making it unlikely all schools will be ready to begin competing in college sports at the same time. Emmert appeared with Dr. Brian Hainline, the NCAA's chief medical officer, in an interview shown on the NCAA's official Twitter account Friday night. Major football conference commissioners have stated their goal is for all 130 teams in 10 conferences across 41 states to begin the season at the same time.

"The HIV resilience framework will be of relevance to a wide range of people involved at all levels of the HIV response. We hope it provides encouragement for government decision makers and policy developers to pursue consistent and enabling policy and legislative environments and work cooperatively between jurisdictions and across departments to achieve best practice. Our consultation suggests that consistent legislation with the goal of supporting strong health outcomes, making disclosure safe, and eliminating stigmatising laws is crucial to creating environments in which people with HIV feel safe to access testing, treatment, and care. The HIV resilience framework also contains valuable insights for those who have responsibility for HIV health program management and service delivery, providing guidance to help ensure that programs, services, interventions or strategies supporting people living with HIV are developed and delivered in a way that is mindful of the interlinked twin goals of building personal resilience and eliminating stigma and discrimination." --President's message (page 6).

"A special challenge of hard rock exploration is to identify targets of interest within complex geological settings. Interpretation of the geology can be made from direct geological observations and knowledge of the area, and from 2D or 3D seismic surveys. These interpretations can be developed into 3D geological models that provide the basis for predictions as to likely targets for drilling and/or mining. To verify these predictions we need to simulate 3D seismic wave propagation in the proposed geological models and compare the simulation results to seismic survey data. To achieve this we convert geological surfaces created in an interpretation software package into discretised block models representing the different lithostratigraphic units, and segment these into discrete volumes to which appropriate density and seismic velocity values are assigned. This approach allows us to scale models appropriately for desired wave propagation parameters and to go from local to global geological models and vice versa. Then we use these digital models with forward modelling codes to undertake numerous 3D acoustic wave simulations. Simulations are performed with single shot and with exploding reflector (located on extracted geological surface) configurations" -- Summary.

"Fixed safety cameras that detect red light running and speeding vehicles are known to be an effective method of controlling driver behaviour and producing road safety benefits. While no definitive best practice for choosing safety camera locations was found in the literature, there are a number of criteria that are frequently used and that make sense: locations with a high number of crashes (particularly injury crashes); locations with a high proportion of speeding vehicles; locations with high traffic volumes; locations with large numbers of unprotected road users (pedestrians and bicyclists); different camera types covering different areas of the road network; and deploying cameras widely throughout the road network. Evaluation of the effects of safety cameras on particular sites and as a whole can be attempted using a number of methodologies: changes in crash numbers before and after installation; changes in vehicle speeds before and after installation; and changes in offence detections from the time of installation onwards. There are limitations with each of these methodologies such that evaluating the effectiveness of an individual safety camera is often not possible. By tracking many safety camera sites for a long period of time, the effect of the safety cameras can be examined but there will always be other factors that may explain any observed changes. A true experiment could be conducted to determine safety camera effects but it would involve deliberate non-treatment of good candidate sites for many years. This study gives a reasonable set of principles for selecting safety camera sites and evaluating their effectiveness. However, the detailed processes for South Australia will depend on what data is available, the resources and funding that can be applied, and political and other considerations." -- page 3.

"Fixed safety cameras that detect speeding (and in some cases red light running) are known to be a generally effective method of controlling driver behaviour and producing road safety benefits. They were first introduced in South Australia in 1988 and are now in operation at more than 150 locations around the State. Data on the speeding and red light running offences recorded at each of the sites are now publicly available. If the number of offences declines over time, this is an indication that the safety cameras are becoming increasingly effective in preventing speeding or red light running behaviour. The offence rates of the five types of safety cameras in use in South Australia were examined on a site by site basis. Safety cameras located in South Australian 50-90 km/h speed limit zones in built-up areas showed a similar overall trend in offence rates: speeding offence rates decreased rapidly during the first two to three years of operation; continued declines in speeding offence rates occurred for many years after that; and red light running offences showed general declines over time but not as consistently or to the same extent as speeding offences. Making the cameras more conspicuous from the time of installation may accelerate their positive effects. Safety cameras may also prevent vehicle speeding on high speed rural roads upon installation (this could not be measured here) but there appears to be little change in offence rates after this time. This is possibly due to the more conspicuous nature of these cameras. The tolerances applied to point to point average speed measurements appear to be the same as applied to spot speed measurements and could reasonably be reduced." -- Summary.
