Simple tool tells whether websites suffered a data breach
Computer scientists have built and successfully tested a tool designed to detect when websites are hacked by monitoring the activity of email accounts associated with them. The researchers were surprised to find that almost 1 percent of the websites they tested had suffered a data breach during their 18-month study period, regardless of how big the companies’ reach and audience are. “No one is above this—companies or nation states— it’s going to happen; it’s just a question of when,” said the senior researcher.

Bioelectronic “nose” detects food spoilage by sensing the smell of death
Strong odors are an indicator that food has gone bad, but there could soon be a new way to sniff foul smells earlier on. Researchers have developed a bioelectronic “nose” that can specifically detect a key decay compound at low levels, enabling people to potentially take action before the stink spreads. It can detect rotting food, as well as be used to help find victims of natural disasters or crimes.

Presenting facts as “consensus” bridges political divide over climate change
New evidence shows that “social fact” highlighting expert consensus shifts perceptions across the U.S. political spectrum – particularly among highly educated conservatives. Facts that encourage agreement are a promising way of cutting through today’s “post-truth” bluster, say psychologists. The researchers found that by presenting a fact in the form of a consensus — “97 percent of climate scientists have concluded that human-caused global warming is happening” – climate change skeptics shift their perceptions significantly towards the scientific “norm.”

Better gas mask filters
In research that could lead to better gas mask filters, scientists have been putting the X-ray spotlight on composite materials in respirators used by the military, police, and first responders, and the results have been encouraging. What they are learning not only provides reassuring news about the effectiveness of current filters in protecting people from lethal compounds such as VX and sarin, but they also provide fundamental information that could lead to more advanced gas masks as well as protective gear for civilian applications.

Explaining differences in climate change views among college graduates
The average American college student has just a 17 percent chance of learning about climate change before graduation through required core courses. The finding may help explain why having a bachelor’s degree doesn’t always lead to increased acceptance of human-caused global warming, according to new research.

Israeli walk-and-fly Rooster robot aids disaster relief
RoboTiCan’s Rooster robot can help reach injured victims of natural disasters where it is not safe to send a human rescue worker. Rooster got its name from the fowl’s preference for walking but being able to fly when necessary, Ofir Bustan, RoboTiCan’s COO, said. “Most of the time it walks, but when it runs into an obstacle, it can hover and fly.” That makes Rooster different from most other search-and-rescue robots, which can either walk or fly but not both – meaning they can get stuck or are too high above the ground to search effectively for survivors.

More-severe climate model predictions likely the most accurate
The climate models that project greater amounts of warming this century are the ones that best align with observations of the current climate, according to a new paper. The findings suggest that the models used by the Intergovernmental Panel on Climate Change, on average, may be underestimating future warming.

Software verifies someone’s identity by their DNA in minutes
In the science-fiction movie “Gattaca,” visitors only clear security if a blood test and readout of their genetic profile matches the sample on file. Now, cheap DNA sequencers and custom software could make real-time DNA-authentication a reality. Researchers have developed a method to quickly and accurately identify people and cell lines from their DNA. The technology could have multiple applications, from identifying victims in a mass disaster to analyzing crime scenes.

Mimicking peregrine falcon attack strategies could help down rogue drones
Researchers have discovered that peregrine falcons steer their attacks using the same control strategies as guided missiles. The findings, which overturn previous assumptions that peregrines’ aerial hunting follows simple geometric rules, could be applied to the design of small, visually guided drones that can take down other ‘rogue’ drones in settings such as airports or prisons.

The Gene Drive Files: Who is in charge of bioengineering research?
Synthetic biology, also called “gene drives” or “bioengineering” – a field that uses technologies to modify or create organisms or biological components – can be used to benefit mankind, but may also be used by terrorists and nation-states to develop design pathogens which could be unleased to kill tens of millions of people. Critics of gene drives are alarmed by the fact that the U.S. military has been the main funder of synthetic biology research in the United States. Given the possible security vulnerabilities related to gene drives developments, a new report by the National Academies of Sciences proposes a framework to identify and prioritize potential areas of concern associated with the field. “While biotechnology is being pursued primarily for beneficial and legitimate purposes, there are potential uses that are detrimental to humans, other species, and ecosystems,” says one of the report’s authors. A nonprofit monitoring synthetic biology research releases new documents ahead of a key UN scientific conference on bioengineering.

Smart alarm system detects attempted break-ins
There is a large selection of glass break detectors on the market. Although these detectors reliably trigger an alarm when window panes break, they do not register all other ways in which burglars can interfere with a pane. To counter this, Fraunhofer researchers have created a new type of alarm system that recognizes any attempt to manipulate the window. It registers temperature changes in real time as well as vibrations caused by external interference with the glass, leaving burglars with no chance.

A turn to the worst in climate change debate
In July, New York magazine published its most-read article ever, surpassing a photo spread of Lindsay Lohan. The topic? Doom. While defying the belief among author David Wallace-Wells’s editors that climate change would be “traffic kryptonite,” the story, titled “The Uninhabitable Earth,” presented an apocalyptic vision in which rising seas flood Miami and Bangladesh, heat and drought cut grain yields in half, diseases spread, and wars rage. Unfortunately, that vision isn’t fiction, but rather Wallace-Wells’s summation of climate change’s little-discussed worst-case scenario for the year 2100.

Nanomaterials’ cryptographic potential may be ultimate defense against hackers
The next generation of electronic hardware security may be at hand as researchers introduce a new class of unclonable cybersecurity security primitives made of a low-cost nanomaterial with the highest possible level of structural randomness. Randomness is highly desirable for constructing the security primitives that encrypt and thereby secure computer hardware and data physically, rather than by programming.

Disaster zones could soon be salvaged by teams of smart devices – here’s how
We will remember 2017 as an appalling year for natural disasters. It comes months after the UN’s head of disaster planning warned that the world is not adequately preparing for disasters. This, he said, risks “inconceivably bad” consequences as climate change makes disasters more frequent and severe. In such circumstances, modern technologies like smartphones, sensors and drones could help enormously, particularly if we can get them to act like an intelligent network. We recently outlined how these three strands from political theory, social science, and biology could be brought together to develop a new paradigm for complex device networks. We see encouraging signs that such thinking is starting to catch on among researchers. These ideas should enable us to develop new approaches that will underpin and enhance a wide variety of human activities – not least when the next disaster strikes. It might even mitigate the effects of climate change, making us better at foreseeing catastrophes and taking steps to avert them.

Economic damage of carbon emissions costlier than earlier thought
The data used to calculate the damage that an additional ton of carbon dioxide has on the global economy has long relied on outdated science. Recent updates modeled raise the calculations of those costs significantly and change the outlook on climate change from a positive for agriculture to a negative. When the most recent science is brought to bear, one of the major models used to calculate the social cost of carbon (SCC) moves the figure to $19.70, an increase of 129 percent.
