Laser helps special forces kill terrorists in a heartbeat | The Times

Special forces could use a laser beam to positively identify terrorists from their heartbeats before they are targeted by drone strikes, snipers or arrest squads. The Pentagon has developed the device for the US military to identify suspects through cardiac signatures — which are unique to a person. Prototypes work at up to 200 metres (650ft) but the system’s creators ... Read More »

The Pentagon Can ID Your Heartbeat Using Laser Beams | Popular Mechanics

The Pentagon has developed a new means of identifying people in conflict zones: laser beams. The Jetson prototype, developed for U.S. special forces, bounces a laser beam off a person to read their unique heartbeat signature, IDing them in seconds. The system is 95 percent accurate and can be used at distances of at least 200 meters, making them useful ... Read More »

Consuming more than five drinks a week could shorten your life | Science Daily

The authors say their findings challenge the widely held belief that moderate drinking is beneficial to cardiovascular health, and support the UK’s recently lowered guidelines. The study compared the health and drinking habits of over 600,000 people in 19 countries worldwide and controlled for age, smoking, history of diabetes, level of education and occupation. The upper safe limit of drinking ... Read More »

Men willing to punish more than women to get ahead | Science Daily

Chapman University has published research measuring gender differences in cooperation and punishment behavior. Results showed that men punish more than women, men obtain higher rank, and punishment by males decreases payoffs for both sexes.

Our emotional state in a given moment may influence what we see, according to findings published in Psychological Science, a journal of the Association for Psychological Science. In two experiments, researchers found that participants saw a neutral face as smiling more when it was paired with an unseen positive image. The research shows that humans are active perceivers, say psychological scientist ... Read More »

‘Everything-repellent’ coating could kidproof phones, homes | Science Daily

Called “omniphobic” in materials science parlance, the new coating repels just about every known liquid. It’s the latest in a series of breakthrough coatings from the lab of Anish Tuteja, U-M associate professor of materials science and engineering. The team’s earlier efforts produced durable coatings that repelled ice and water, and a more fragile omniphobic coating. The new omniphobic coating ... Read More »
