• Psychopathic brains’ wiring leads to dangerous and violent actions

    Researchers have found that psychopaths’ brains are wired in a way that leads them to over-value immediate rewards and neglect the future consequences of potentially dangerous or immoral actions. Psychopaths “are not aliens, they’re people who make bad decisions,” one researchers said. “The same kind of short-sighted, impulsive decision-making that we see in psychopathic individuals has also been noted in compulsive over-eaters and substance abusers.” Psychopaths are “exactly what you would expect from humans who have this particular kind of brain wiring dysfunction.”

  • Quantum technology holds promise of a future without fakes

    Counterfeit products are a huge problem - from medicines to car parts, fake technology costs lives. Every year, imports of counterfeited and pirated goods around the world cost nearly $0.5 trillion in lost revenue. Counterfeit medicines alone cost the industry over $200 billion every year. They are also dangerous to our health – around a third contain no active ingredients, resulting in a million deaths a year. Researchers exhibiting at the Royal Society Summer Science Exhibition believe we are on the verge of a future without fakes thanks to new quantum technology.

  • Hybrid structures combining concrete and wood increasingly popular

    Houses can be made of wood, as they were in the past – or of concrete, as they are today. To build for tomorrow, the two building methods are being combined: these hybrid structures, which contain both wood and concrete elements, are becoming increasingly popular in contemporary architecture. The building material offers the construction industry new possibilities and is based in large part on renewable resources.

  • Resolving conflict in estimates of climate change

    Researchers have resolved a conflict in estimates of how much the Earth will warm in response to a doubling of carbon dioxide in the atmosphere. That conflict — between temperature ranges based on global climate models and paleoclimate records and ranges generated from historical observations — prevented the United Nations’ Intergovernmental Panel on Climate Change (IPCC) from providing a best estimate in its most recent report for how much doubled CO2 emissions will warm the Earth.

  • Smart quadcopters find their way on their own -- without human help or GPS

    Phase 1 of DARPA’s Fast Lightweight Autonomy (FLA) program concluded recently following a series of obstacle-course flight tests in central Florida. Over four days, three teams of DARPA-supported researchers huddled under shade tents in the sweltering Florida sun, fine-tuning their sensor-laden quadcopter unmanned aerial vehicles (UAVs) during the intervals between increasingly difficult runs. The quadcopters slalomed through woodlands, swerved around obstacles in a hangar, and reported back to their starting point all by themselves.

  • New bracing for durable structures in earthquake-prone regions

    Across the world, severe earthquakes regularly shake entire regions. More than two billion people live in danger zones – many of them in structures not built to withstand an earthquake. Together with partners from industry, researchers are developing building materials designed to prevent buildings from collapsing in a natural disaster.

     

  • Addressing the threat of vehicle-borne IEDs

    In July of 2016, a refrigerator truck packed with explosives detonated next to a crowded apartment block in Baghdad’s Karrada neighborhood. The blast killed 323 people and was one of the worst Vehicle–Borne Improvised Explosive Device (VBIED also known as car bombs) attacks ever recorded. On 30 May 2017, a VBIED in a tanker truck ripped through the embassy quarter of Kabul, killing more than 150 people. DHS S&T has taken measures to address this threat directly.

  • Global warming damages U.S. economy, increases inequality

    Unmitigated climate change will make the United States poorer and more unequal, according to a new study. The pioneering study is the first of its kind to price warming using data and evidence accumulated by the research community over decades. From this data, the researchers estimate that for each 1 degree Fahrenheit (0.55 degrees Celsius) increase in global temperatures, the U.S. economy loses about 0.7 percent of Gross Domestic Product, with each degree of warming costing more than the last.

  • Drones that drive

    Being able to both walk and take flight is typical in nature — many birds, insects, and other animals can do both. If we could program robots with similar versatility, it would open up many possibilities: Imagine machines that could fly into construction areas or disaster zones that aren’t near roads and then squeeze through tight spaces on the ground to transport objects or rescue people. Researchers from MIT are aiming to develop robots that can both maneuver around on land and take to the skies.

  • As melting of Greenland ice sheet intensifies, sea level rise accelerates

    A new study says that the pace of sea level rise has increased significantly over the past quarter-century, with the thawing of Greenland’s ice sheet playing a major role in the steady rise of the oceans. The study said that Greenland’s ice sheet accounted for more than 25 percent of sea level rise in 2014, compared to just 5 percent in 1993.

  • Rising seas could create 2 billion refugees by 2100

    In the year 2100, 2 billion people – about one-fifth of the world’s population – could become climate change refugees due to rising ocean levels. Those who once lived on coastlines will face displacement and resettlement bottlenecks as they seek habitable places inland, according to new research. Feeding that population will require more arable land even as swelling oceans consume fertile coastal zones and river deltas, driving people to seek new places to dwell.

  • Studying public reaction before and after a terror attack

    It is a rare opportunity when public policy professionals have information at their fingertips for comparing public views around a traumatic event before implementing new policies. A new study examine how those exposed to local terrorist acts through media sources perceive the risk of terrorism before and immediately after an event—and discuss how that difference in perception may shape measures that are proposed in response.

  • Fact Check: is the type of cladding used on Grenfell Tower actually banned in Britain?

    Cladding was added on tower blocks built in the 1960s and 1970s such as Grenfell Tower to improve the thermal performance of the flats and in some cases prevent material deteriorating and falling from the existing facades. These flats are often homes to some of the poorest in society and improving the facades may cut their energy bills to less than a half. This also means that they can adequately heat their homes to avoid condensation and mold growth inside. After the devastating fire at Grenfell Tower, the Metropolitan Police is considering whether to bring manslaughter (or other) charges relating to the tower block’s insulation, which it says failed safety tests.

  • New subsidence map highlights sinking Louisiana coast

    Researchers at Tulane University have developed a subsidence map of coastal Louisiana, putting the rate at which this region is sinking at just over one third of an inch per year. The map, published in GSA Today, has long been considered the “holy grail” by researchers and policy makers as they look for solutions to the coastal wetland loss crisis, the researchers said.

  • Climate can rapidly change at tipping points

    A new study shows that gradual changes in the atmospheric CO2 concentration can induce abrupt climate changes. During the last glacial period, within only a few decades, the influence of atmospheric CO2 on the North Atlantic circulation resulted in temperature increases of up to 10 degrees Celsius in Greenland – as indicated by new climate calculations from researchers.
