US moves to tackle scourge of 'robocalls'
"Hello? Who's calling?" For many Americans these days, the call is coming from a "bot" or automated program that seeks to trick them into giving up money or important personal data.

Model explores how statins alter multiple sclerosis outcomes
(HealthDay)—Simvastatin's beneficial effects on clinical outcomes and brain atrophy in patients with multiple sclerosis (MS) are largely independent of cholesterol levels, according to a post hoc study published in the May 28 issue of the Proceedings of the National Academy of Sciences.

Dashing the dream of ideal 'invisibility' cloaks for stress waves
Whether Harry Potter's invisibility cloak, which perfectly steers light waves around objects to make them invisible, will ever become reality remains to be seen, but perfecting a more crucial cloak is impossible, a new study says. It would have perfectly steered stress waves in the ground, like those emanating from a blast, around objects like buildings to make them "untouchable."

New computer attack mimics user's keystroke characteristics and evades detection
Ben-Gurion University of the Negev (BGU) cyber security researchers have developed a new attack called Malboard. Malboard evades several detection products that are intended to continuously verify the user's identity based on personalized keystroke characteristics.

How brassinosteroid signaling makes roots grow longer under nitrogen deficiency
As sessile organisms, plants rely on their ability to adapt the development and growth of their roots in response to changing nutrient conditions. One such response, known to be displayed by plants grown in low nitrogen conditions, is the elongation of primary and lateral roots to explore the surrounding soil. This adaption to the lack of the essential element nitrogen is of particular interest, as it reflects a "foraging strategy," by which the root system can exploit nutrients from a larger soil volume. Until recently, this was the least understood nitrogen-dependent root response. Scientists from the IPK in Gatersleben have now identified the hormone pathway regulating root foraging under low nitrogen conditions and a signalling component that modulates the intensity of this response. These findings open up the possibility of breeding crops with root systems enabling more efficient nitrogen uptake.

Somebody's watching you: The surveillance of self-driving cars
Picture the future, where driving is a thing of the past. You can hop in your car or one from a ride-share, buckle up and tell the car where you want to go. During your ride, you can check your email and look up a few things online through your dashboard. Meanwhile, your whereabouts and other details are being tracked remotely by companies. As self-driving cars develop further, autonomous vehicles will play a much larger role in the digital economy as car companies and others harness personalized customer information through geospatial and navigation technologies, combining it with existing financial consumer profiles, according to a study in Surveillance and Society.

Probing semiconductor crystals with a sphere of light
Tohoku University researchers have developed a technique using a hollow sphere to measure the electronic and optical properties of large semiconducting crystals. The approach, published in the journal Applied Physics Express, improves on current photoluminescence spectroscopy techniques and could lead to energy savings for mass producers, and thus consumers, of power devices.

Scientists remind immune cells whose side they should be on
International group of scientists in the joint study of the laboratory of the Wistar Institute, University of Pittsburgh, and I.M. Sechenov First Moscow State Medical University discovered the change in activity of one of the immune cells types called neutrophils during cancer development: they begin to prevent other immune cells from fighting tumors, and thus decelerate treatment. The scientists found protein causing such changes and demonstrated that suppressing its activity in the cells delays cancer development. The research details are published in Nature.
