Smaller city effort to aid chronically homeless can be successful
Creating a municipally funded team to provide intensive services to chronically homeless people who use a large amount of public services can help the individuals get off the streets, while also reducing spending on services such as police services and emergency medical care, according to a new RAND Corporation study.

Q&A: Tanning beds raise risk for skin cancer
Dear Mayo Clinic: My daughter and her friends are all talking about going to a tanning bed. I suggested to my daughter that she get a spray tan instead, but I don't think I've convinced her since she's under the impression that tanning beds are somewhat safe. Is there any kind of tanning bed that is safe and that won't damage the skin?

Ancient DNA sheds light on Arctic hunter-gatherer migration to North America 5,000 years ago
The first humans in North America arrived from Asia some time before 14,500 years ago. The next major stream of gene flow came about 5000 years ago, and is known to archaeologists as Paleo-Eskimos. About 800 years ago, the ancestors of the present-day Inuit and Yup'ik people replaced this population across the Arctic. By about 700 years ago, the archaeological evidence for the Paleo-Eskimo culture disappeared. Their genetic legacy in living populations has been contentious, with several genetic studies arguing that they made little contribution to later North Americans.

To fight tuberculosis infection, early protection is crucial
In the first days after the tuberculosis (TB) bacteria infect the body, a flurry of immune cells are activated to fight the infection. Now, researchers have identified a master cell that coordinates the body's immune defenses in those crucial early days, according to a new study from Washington University School of Medicine in St. Louis and Africa Health Research Institute in KwaZulu-Natal, South Africa.

Autonomous boats can target and latch onto each other
The city of Amsterdam envisions a future where fleets of autonomous boats cruise its many canals to transport goods and people, collect trash, or self-assemble into floating stages and bridges. To further that vision, MIT researchers have given new capabilities to their fleet of robotic boats—which are being developed as part of an ongoing project—that lets them target and clasp onto each other, and keep trying if they fail.

Investigating cardiovascular health among Asian Americans
Physician-scientists from the University of Alabama at Birmingham and the University of Minnesota have recently collaborated to assess the prevalence of cardiovascular risk factors and key cardiovascular diseases among Asian Americans. Among their landmark findings, recently published in the journal American Journal of Cardiology, is that American-born Asian Americans had higher odds of poor diet and elevated blood pressure than foreign-born Asian Americans—including among the most educated and affluent.

Maestro: a new attack that orchestrates malicious flows with BGP
Researchers at the University of Tennessee have recently identified the Maestro attack, a new link flooding attack (LFA) that leverages plane traffic control engineering techniques to concentrate botnet-sourced distributed denial of service (DDos) flows on transit links. In their paper, recently published on arXiv, the researchers outlined this type attack, tried to understand its scope and presented effective mitigations for network operators who wish to insulate themselves from it.

Deep learning techniques teach neural model to 'play' retrosynthesis
Researchers, from biochemists to material scientists, have long relied on the rich variety of organic molecules to solve pressing challenges. Some molecules may be useful in treating diseases, others for lighting our digital displays, still others for pigments, paints, and plastics. The unique properties of each molecule are determined by its structure—that is, by the connectivity of its constituent atoms. Once a promising structure is identified, there remains the difficult task of making the targeted molecule through a sequence of chemical reactions. But which ones?

Bats have an ambulance in their ears
Anybody who has been passed by an ambulance at high speed has experienced a physical effect called the Doppler shift: As the ambulance moves toward the listener, its motion compresses the siren's sound waves and raises the sound pitch. As the ambulance moves away from the listener, the sound waves get dilated and the pitch is lowered. A listener wearing a blindfold could use this Doppler shift pattern to track the motion of the ambulance.
