(Princeton University, Engineering School) A team of researchers has developed a new way to control and measure atoms that are so close together no optical lens can distinguish them.
Popular Princeton online classes run the gamut from public health and architectural design to psychology and philosophy courses.
(University of Texas at Arlington) University of Texas at Arlington doctoral students Daniel Palmquist and Vijay Gopal, along with Davide Vigano, a postdoctoral researcher, will study, collaborate and conduct experiments with the Princeton University Plasma Physics Laboratory group, thanks to a Department of Energy grant.
(Purdue University) Researchers are developing ways to protect the software of autonomous systems on the battlefield by making their machine learning algorithms more secure.
(Princeton University) The "mismatch hypothesis" argues that our bodies evolved to digest the foods that our ancestors ate, and that human bodies will struggle and largely fail to metabolize a radically new set of foods. This intuitive idea is hard to test directly, but the Turkana, a pastoralist population in remote Kenya, present a natural experiment: genetically homogenous populations whose diets stretch across a lifestyle gradient from relatively "matched" to extremely "mismatched" with their recent evolutionary history.
(Princeton University) Two Princeton professors, architect Stefana Parascho and engineer Sigrid Adriaenssens, used industrial robots to create a striking and unique LightVault. Critically, the LightVault reduced resource use in two ways: eliminating the need for forms or scaffolding during construction, and improving the vault's structural efficiency by making it doubly curved, which reduced the amount of material required. These were only possible because of the robots' strength and precision.
(Princeton University) Changes to regional climates brought on by global warming could make it so that areas such as the American Southwest that are currently considered ideal for solar power would be less viable in the future, a Princeton-based study suggests. Higher surface temperatures will lead to more moisture, aerosols and particulates in the atmosphere, which may result in less solar radiation and more cloudy days. The study is the first to assess the day-to-day reliability of solar energy under climate change.
(Princeton University, Engineering School) Researchers at Princeton University have developed a tool that flags potential biases in sets of images used to train artificial intelligence (AI) systems. The work is part of a larger effort to remedy and prevent the biases that have crept into AI systems that influence everything from credit services to courtroom sentencing programs.
(Princeton University, Engineering School) With implications for the transmission of diseases like COVID-19, researchers have found that ordinary conversation creates a conical 'jet-like' airflow that quickly carries a spray of tiny droplets from a speaker's mouth across meters of an interior space.
(Princeton University) Princeton researchers will help lead a $1 million federally funded project that will use artificial intelligence to simulate the nation's natural groundwater system in an effort to improve groundwater management, as well as flood and drought preparedness. The project was one of 29 nationwide selected for the first phase of the National Science Foundation's new Convergence Accelerator program.
Amy McGrath's challenge against Mitch McConnell is raking in tons of money, but Democrats with actual chances of winning need that money.
(Princeton University, Engineering School) Limitations in DNA sequencing technology make it difficult to detect some major mutations often linked to cancer, such as the loss or duplication of parts of chromosomes. Now, methods developed by Princeton computer scientists will allow researchers to more accurately identify these mutations in cancerous tissue, yielding a clearer picture of the evolution and spread of tumors than was previously possible.
(Princeton University, Engineering School) Researchers at Princeton University have created a new and improved way to more precisely control genetically engineered bacteria: by simply switching the lights on and off. Working in E. coli, the workhorse organism for scientists to engineer metabolism, researchers developed a system for controlling one of the key genetic circuits needed to turn bacteria into chemical factories that produce valuable compounds such as the biofuel isobutanol.
(DOE/Princeton Plasma Physics Laboratory) New funding will upgrade diagnostics on the National Spherical Tokamak Experiment-Upgrade, the flagship facility at PPPL.
(Princeton University, Engineering School) In one of the first comprehensive assessments of the fuel economy standards in the US, researchers found that, over their 40-year history, the standards helped reduce reliance on foreign oil producers, saved $5 trillion in fuel costs and prevented 14 billion metric tons of carbon from being released into the atmosphere. The standards (known as CAFE standards), first enacted to reduce foreign oil dependence, were cost-effective, fair, durable and adaptive, the researchers found.
US law enforcement and other authorities used force while intervening in nearly 400 Black Lives Matter protests since police killed George Floyd in May, according to new data that paints the clearest portrait yet of the historic unrest that’s swept across the country this summer.Figures from the US Crisis Monitor offer a bleak forecast of escalating political violence heading into a contentious election. While most of the protests have been non-violent, police or other authorities intervened in about 725 Black Lives Matter protests in the US between May 24 and August 22, sometimes using force – including tear gas, rubber bullets, or beating demonstrators with batons, data shows. There were also over 100 instances of government violence directed against the media during this period. We’re seeing increased proliferation of groups like militias that are taking up arms, some of whom are becoming violent.Dr. Roudabeh KishiOn top of that, the Crisis Monitor – a joint effort of the Armed Conflict Location & Event Data Project (ACLED), a nongovernmental organisation, and the Bridging Divides Initiative at Princeton University – identified over 100 instances of non-state actors, including at least 20 distinct far-right militia groups, intervening in Black Lives Matter demonstrations, sometimes violently, since May 24.There were also dozens of cases of individual perpetrators, some linked to white supremacist groups like the KKK, driving vehicles into Black Lives Matter demonstrators.And things could get worse.“I think we have all of the pieces at hand to make a perfect storm, so to speak, as we march closer and closer to the election,” said Dr. Roudabeh Kishi, the director of research and innovation for ACLED’s US Crisis Monitor.There were nearly 11,000 demonstrations in the US between May 24 and August 22 – accompanied by terrifying instances of state repression, including the violent removal of protesters outside the White House to make room for a presidential photo-op, and the abduction of protesters by federal agents into unmarked vans driving around Portland, Oregon. There have also been increasing instances of far-right vigilantes confronting left-wing protesters.In the past week, three people have been shot and killed at demonstrations. Last Tuesday in Kenosha, Wisconsin, a 17-year-old, marching with a local group of armed vigilantes, allegedly shot and killed two anti-racist protesters and severely injured another. On Saturday, a member of the far-right group Patriot Prayer, which is known for violently attacking leftists in the northwestern US, was shot and killed during a pro-Trump demonstration in Portland.“We’re seeing increased violence, like in the streets, within demonstrations. We’re seeing increased heavy-handedness by the state,” Kishi told HuffPost. “We’re seeing increased proliferation of groups like militias that are taking up arms, some of whom are becoming violent, like we just saw in Kenosha.”There’s been a sharp increase in the state cracking down on protests when compared to last year, Kishi said.In July 2019, when the US was experiencing a wave of unrest over the horrific abuses of immigrants at government detention camps, police or government forces only intervened in about 2% of demonstrations, Kishi said. This July, those forces clamped down on 9% of protests. Kishi said these trends, combined with hostile rhetoric from the White House and the way social media platforms allow extremists to mobilise, make her very worried about the coming months. Right-wing groups have organised about 360 demonstrations in opposition to Black Lives Matter, often under the banner of “Blue Lives Matter.” Some demonstrations were also organised in support of Trump or Confederate statues.  All told, according to ACLED’s data, over 40 of those right-wing demonstrations have resulted in violence since May. This adds to recent findings from the Centre for Analysis of the Radical Right, which identified nearly 500 incidents of vigilantes or far-right activists confronting Black Lives Matter demonstrators since May. Those incidents include 64 cases of simple assault, 38 cases of vigilantes driving cars into demonstrators, and nine times that shots were fired at protesters.At least six left-wing protesters have been shot during the demonstrations, three of whom died.The president, meanwhile, has attempted to make “law and order” a central pillar of his re-election campaign, in part by signalling his opposition to the nationwide protests.On Sunday, Trump lashed out against “antifa” and Portland Mayor Ted Wheeler.“The people of Portland won’t put up with no safety any longer,” Trump tweeted. “The Mayor is a FOOL. Bring in the National Guard!”On Monday, White House press secretary Kayleigh McEnany refused to say whether the president would condemn the killing of two protesters in Kenosha. It’s this type of messaging from the White House, in support of state repression of protests and tacit tolerance of far-right vigilantes, that has Kishi and the team at ACLED so worried.“I think as you’re closer to November, this hyperpolarisation is kind of coming to a front,” Kishi said.The weeks immediately before and after the election could be particularly fraught, Kishi warned, pointing to the possibility of widespread voter suppression and growing uncertainty about whether Americans will accept the election’s results.The US Crisis Monitor hopes to be around to track the political unrest come November. Funding for the project is set to dry up in a matter of weeks, but Kishi and her team are pursuing more funding to continue their work.
(Princeton University) Princeton University will have a major leadership role in one of the five new multi-institution centers for the advancement of quantum science research announced by the U.S. Department of Energy. Princeton Professor Andrew Houck will be deputy director of the new Co-Design Center for Quantum Advantage (C2QA) headquartered at Brookhaven National Laboratory.
(University of British Columbia) The "Cold Tube" can offer relief from the summer heat without relying on air conditioning. It uses half the energy of conventional air conditioners and can be used outdoors or indoors.
(Princeton University, Engineering School) New research has found radiant cooling could keep people cool without conditioning or dehumidifying the air and use much less energy than comparable AC. In this Q&A, the researchers comment on why this research is so relevant not just in a warming world, but also in a contagious one where equipping indoor spaces with outdoor levels of air flow is part of the strategy to contain the spread of the COVID-19 virus.
(Princeton University, Engineering School) What do we mean by the word beautiful? It depends not only on whom you ask, but in what language you ask them. According to a machine learning analysis of dozens of languages conducted at Princeton University, the meaning of words does not necessarily refer to an intrinsic, essential constant. Instead, it is significantly shaped by culture, history and geography.
