The arithmetic of gun control and gun violence
The most comprehensive statistical study of gun violence in the United States – examining data going back to the First World War – finds that, in more common domestic and one-on-one crimes, reduced legal gun availability, if properly enforced, is likelier to lower deaths. In rare mass shootings, armed citizens might save lives if sufficiently trained to avoid accidentally shooting fleeing bystanders. The authors note, though, that key parts of their equations should be studied more closely: the fraction of offenders who illegally possess a gun, the statistical degree of protection provided by legal gun ownership, and the number of people who are legally carrying a gun when attacked. Comprehensive data in those areas, they say, could further aid the development and implementation of effective policies.

Research priorities for understanding public health aspects of gun-related violence
A new report from the Institute of Medicine (IOM) and National Research Council (NRC) proposes priorities for a research agenda to improve understanding of the public health aspects of gun-related violence. The committee which wrote the report said significant progress can be achieved in three to five years through a research program that addresses five high-priority areas: the characteristics of gun violence, risk and protective factors, prevention and other interventions, gun safety technology, and the influence of video games and other media.

Using invasive trees to develop jet fuel for U.S. Navy fighter jets
In western U.S. rangelands, native juniper and pinyon pine trees are spreading beyond their historical ecological niches and disrupting the environmental balance of their expanded range. Preliminary estimates suggest harvesting some of these hardy invaders every year could supply enough biomass to produce millions of gallons of renewable jet fuel for the U.S. Navy fighter jets.

Hollow-core optical fiber to enable high-power military sensors
The intensity of light that propagates through glass optical fiber is fundamentally limited by the glass itself. A novel fiber design using a hollow, air-filled core removes this limitation and significantly improves performance by forcing light to travel through channels of air, instead of the glass around it. DARPA’s spider-web-like, hollow-core fiber design is the first to demonstrate single-spatial-mode, low-loss and polarization control — key properties needed for advanced military applications such as high-precision fiber optic gyroscopes for inertial navigation.

Angry lawmakers warn NSA to curb surveillance operations
John Inglis, the deputy director of the National Security Agency (NSA), told angry lawmakers yesterday that his agency’s ability to analyze phone records and online behavior is greater than what the agency had previously revealed. Inglis told members of the House Judiciary Committee that NSA analysts can perform “a second or third hop query” through its collections of telephone data and Internet records in order to find connections to terrorist organizations. Representative James Sensenbrenner (R-Wisconsin), the author of the 2001 Patriot Act, warned the intelligence officials testifying before the committee that unless they rein in the scope of their surveillance on Americans’ phone records, “There are not the votes in the House of Representatives” to renew the provision after its 2015 expiration. “You’re going to lose it entirely,” he said.

Automatic license plate readers used to collect, store data on millions of Americans
Automatic license plate readers are the most widespread location tracking technology available to law enforcement. Mounted on patrol cars or stationary objects like bridges, they snap photos of every passing car, recording their plate numbers, times, and locations. At first the captured plate data was used just to check against lists of cars law enforcement hoped to locate for various reasons (to act on arrest warrants, find stolen cars, etc.). Increasingly, however, all of this data is being fed into massive databases that contain the location information of many millions of innocent Americans stretching back for months or even years.

How Quickly Could Iran Make Nuclear Weapons Today?
For Iran, two of the three poles in the tent of building nuclear weapons – fissile material and delivery vehicles — are essentially complete. It will take them one week to enrich enough uranium to 90 percent for one bomb (and one month to enrich enough uranium for six bombs). Iran also has a variety of delivery systems, including nuclear-capable missiles: the delivery pole is ready. Weaponization is the pole that needs more work. The accelerated weaponization program can be accomplished in a matter of six months.
Fifty-Five Hours of Risk: The Dangerous Implications of Slow Attack Attribution
Assuming that its foreign adversaries’ recent violent threats are to be taken seriously, and that the likelihood of a direct attack against the United States is, if not on the rise, at least significant enough to warrant serious attention, the United States has an urgent mandate to prepare effective cognitive defenses. Foremost among these is the ability to quickly and accurately attribute attacks to their originators, and to deliver that information to the public through a trustworthy vehicle.
What Can We Learn from the Nation’s Historic Decline in Murders?
The U.S. endured a spike in gun violence during the pandemic, but it’s subsiding in many places. A researcher puts the latest homicide statistics into context — and warns lawmakers not to become complacent.
Is Left-Wing Terrorism Making a Comeback in Germany? Analyzing the “Engel – Guntermann Network”
For Germany, the reemergence of more violence orientated left-wing extremist actors has diversified the threat posed by non-state actors even further. Violent left-wing extremism is also of growing concern across Europe. While left-wing violent extremism does not currently represent as acute a threat as currently manifested by jihadist and right-wing terrorist attacks, the recent concerning trend among German left-wing extremists is toward greater violence and transnationalism.
