• ForensicsNew technique can tell whether a fingerprint belongs to a male or female

    Culprits beware: researchers are taking crime scene fingerprint identification to a new level. They have discovered a straightforward concept for identifying whether a culprit is male or female. It is based on the content in fingerprints — specifically amino acids. Amino acid levels in the sweat of females are about twice as high as in males. There is also a slightly different distribution, due mostly to hormonal differences. The same is true for amino acids left behind in fingerprints.

  • FirefightingNew sensors detect cable fire before it starts burning

    Fires are frequently caused by smoldering cables. New sensors now help detect such smoldering fires at an early stage by analyzing the plastic vapors released by overheated insulating cables. Scientists have developed these hybrid sensors that combine measurement processes with data evaluation. These detect the gases released from the plastic coating due to heating and reliably identify and analyze the gas mixture and its concentration.

  • Guns & terrorismNYPD commissioner to Congress: Do not allow people on terror watch list to buy guns

    NYPD Commissioner Bill Bratton the other day called on Congress today to “start getting serious” about fixing the loophole which allows individuals on the U.S. terror watch list legally to purchase firearms in the United States. Bratton said: “If Congress really wants to do something instead of just talking about something, help us out with that terrorist watch list, those thousands of people that can purchase firearms in this country. I’m more worried about them than I am about Syrian refugees.”

  • Terrorism appN.Y. State Police app helps citizens report suspicious activity

    The New York State Police is urging citizens to download a new digital app which allows citizens to capture and report suspicious activity with their smart phones. The app is part of the “See Something, Send Something” campaign which aims to turn willing citizens into the eyes and ears of law enforcement. For example, if a citizen notices an unattended package at a train station of an airport, they could use the app to alert law enforcement.

  • EncryptionTech companies: weakening encryption would only help the bad guys

    Leading technology companies — Apple, Microsoft, Google, Samsung, Twitter, Facebook, and fifty-six other technology companies — have joined forces to campaign against weakening end-to-end encryption, insisting that any weakening of encryption would be “exploited by the bad guys.” Apple’s chief executive Tim Cook recently asserted that “any backdoor is a backdoor for everyone.”

  • SurveillanceAfter Paris, it’s traditional detective work that will keep us safe, not mass surveillance

    By Pete Fussey

    Before the dust has even settled from the attacks on Paris, familiar calls for greater surveillance powers are surfacing. The desire for greater security is understandable, but that doesn’t mean we should suspend our judgement on the measures proposed to bring it about. It’s widely accepted that intelligence work is the most effective form of counter-terrorism, and that the best intelligence comes from community engagement, not coercion. So we must be wary of the evangelism of those pushing technological solutions to security problems, and the political clamor for mass surveillance.

  • ISISISIS “trying to obtain chemical, nuclear weapons”: U.K. government

    British prime minister David Cameron said yesterday that the government security review has warned that ISIS and al-Qaeda are trying to get their hands on chemical and nuclear weapons. Cameroon referred to the security review in a speech in which he called on Members of Parliament to approve U.K. air strikes in Syria within a week. The British government pledged allocation additional resources for new equipment and the creation of within the Army of two new rapid response “strike brigades” of 5,000 soldiers each. The number of civilian jobs in the Ministry of defense, though, will be heavily reduced.

  • DetectionSmart sensor detects single molecule in chemical compounds

    Researchers have developed a smart sensor that can detect single molecules in chemical and biological compounds — a highly valued function in medicine, security, and defense. The researcher used a chemical and biochemical sensing technique called surface-enhanced Raman spectroscopy (SERS), which is used to understand more about the make-up of materials.

  • Encryption & terroristsTelegram IM app recalibrates policies after Paris attacks

    Pavel Durov, the creator of the popular instant messaging app Telegram, has said that following the Paris terrorist attacks, his company has blocked dozens of accounts associated with the jihadist Islamic State group. As is the case with other technology companies, Telegram is trying to negotiate the balance between privacy and security: the same privacy-enhancing technology which keeps customers’ communication private, also helps terrorists communicate with each other and plot attacks safe from monitoring and surveillance by intelligence agencies and law enforcement.

  • First responseDemonstrating technologies for disaster response

    Radiological incidents such as Chernobyl and Fukushima illustrate the need for effective coordination of federal, state, and local agencies in response efforts. Earlier this year, the Department of Homeland Security (DHS) Science and Technology Directorate’s (S&T) National Urban Security Technology Laboratory (NUSTL) and the Environmental Protection Agency (EPA) demonstrated new technology developments at the Columbus, Ohio, Battelle Memorial Institute facility that will enable more effective radiological decontamination.

  • Terror in Paris2 dead, 7 arrested in French police raid on apartment building in search of attacks’ mastermind

    About 200 members of the special units of the French police early Wednesday morning (Paris time) swooped on the Parisian banlieue, or suburb, of Saint-Denis – where the Stade de France, one of the sites of Friday’s terrorist attacks, is located – and arrested seven people. Two people were killed. One of the dead was a young woman who blew herself up with a suicide vest. French Prosecutor Francois Molins told reporters that the operation was a result of a credible tip — in all likelihood, a police informer who resides in the neighborhood — suggesting Abdelhamid Abbaaoud, a 27-year-old Belgian of Moroccan origin, was holed up in an apartment in a residential building.

  • EncryptionParis terrorist attacks reignite debate over end-to-end encryption, back doors

    The exact way the terrorists who attacked France last Friday communicated with each other, and their handlers, in the run-up to the attack is not yet clear, but the attack has prompted law enforcement and intelligence agencies in Europe and the United States to renew their call to regulate the use of new encryption technologies which allow users to “go dark” and make it difficult, if not altogether impossible, to retrieve the contents of communication.

  • EarthquakesDiscovery of “hidden earthquake” challenges tsunami early-warning systems

    Seismologists studying the 2011 Chile earthquake have discovered a previously undetected earthquake which took place seconds after the initial rupture. This newly discovered phenomena which they have called a “closely spaced doublet” presents a challenge to earthquake and tsunami early warning systems as it increases the risk of larger-than-expected tsunamis in the aftermath of a typical subduction earthquake.

  • Terror in ParisU.K. put special British police unit on standby in the wake of Paris attacks

    In the early hours of Saturday, following the previous evening’s terrorist attacks in Paris, the British government put a special British police unit on standby for an emergency national mobilization of officers. The move was a precautionary measure taken as the government weighed placing the United Kingdom on its highest state of terrorist alert. There are forty-three local police forces in England and Wales, and raising the terrorist threat level to critical — the highest would have triggered the dispatching of officers from some of these local forces patrol sites and neighborhood in the country’s big cities.

  • In the trenchesMost people object to fully autonomous weapons: Survey

    Public opinion is against the use of autonomous weapons capable of identifying and destroying targets without human input, according to a new survey. “It has been said that future wars will be fought with completely automated systems,” said one of the researchers behind the survey. “The survey results clearly show that more public discussion is necessary so that we can make intelligent decisions about robotic weapon technologies.”
