Berkeley Lab Confirms Thirdhand Smoke Causes DNA Damage

A study led by researchers from Lawrence Berkeley National Laboratory has found for the first time that thirdhand smoke—the noxious residue that clings to virtually all surfaces long after the secondhand smoke from a cigarette has cleared out—causes significant genetic damage in human cells.

Solar tsunami used to measure Sun’s magnetic field

A solar tsunami observed by NASA’s Solar Dynamics Observatory (SDO) and the Japanese Hinode spacecraft has been used to provide the first accurate estimates of the Sun’s magnetic field.

Solar tsunamis are produced by enormous explosions in the Sun’s atmosphere called coronal mass ejections (CMEs). As the CME travels out into space, the tsunami travels across the Sun at speeds of up to 1000 kilometres per second.

Similar to tsunamis on Earth, the shape of solar tsunamis is changed by the environment through which they move. Just as sound travels faster in water than in air, solar tsunamis have a higher speed in regions of stronger magnetic field. This unique feature allowed the team, led by researchers from UCL’s Mullard Space Science Laboratory, to measure the Sun’s magnetic field. The results are outlined in a paper soon to be published in the journal Solar Physics. (more…)

Saving Lives Worldwide by Training International Volcano Scientists

VANCOUVER, Wash. – Scientists and technicians who work at volcano observatories in nine countries are visiting Mount St. Helens and the U.S. Geological Survey Volcano Science Center’s Cascades Volcano Observatory this week to learn techniques for monitoring active volcanoes. Organized by the Center for the Study of Active Volcanoes at the University of Hawaiʻi, Hilo, with support from the VSC-managed joint USGS-USAID Volcano Disaster Assistance Program, the annual program has been training foreign scientists for 22 years. This year’s class includes volcano scientists from Ecuador, Colombia, Peru, Costa Rica, El Salvador, Canada, Indonesia, Italy, and Papua New Guinea.

The International Training Program in Volcano Hazards Monitoring is designed to assist other nations in attaining self-sufficiency in monitoring volcanoes and reducing the risks from eruptions. Through in-class instruction at two USGS volcano observatories, and field exercises in Hawaiʻi and at Mount St. Helens, U.S. scientists are providing training on monitoring methods, data analysis and interpretation, and volcanic hazard assessment, and participants are taught about the use and maintenance of volcano monitoring instruments. Additionally, participants learn about focusing on forecasting and rapid response during volcanic crises, and how to work with governing officials and the news media to save lives and property.

Companies Look at Wrong Things When Using Facebook to Screen Job Applicants

Employers are increasingly using Facebook to screen job applicants and weed out candidates they think have undesirable traits. But a new study from North Carolina State University shows that those companies may have a fundamental misunderstanding of online behavior and, as a result, may be eliminating desirable job candidates.

Researchers tested 175 study participants to measure the personality traits that companies look for in job candidates, including conscientiousness, agreeableness and extraversion. The participants were then surveyed on their Facebook behavior, allowing researchers to see which Facebook behaviors were linked to specific personality traits. (more…)

Good Vibrations: Mediating Mood Through Brain Ultrasound

Ultrasound vibrations applied to the brain may affect mood, UA researchers have discovered. The finding potentially could lead to new treatments for psychological and psychiatric disorders.

University of Arizona researchers have found in a recent study that ultrasound waves applied to specific areas of the brain appear able to alter patients’ moods. The discovery has led the scientists to conduct further investigations with the hope that this technique could one day be used to treat conditions such as depression and anxiety.

Dr. Stuart Hameroff, professor emeritus of the UA’s departments of anesthesiology and psychology and director of the UA’s Center for Consciousness Studies, is lead author on the first clinical study of brain ultrasound, which was published in the journal Brain Stimulation. (more…)

Outsmarting hackers

US Cyber Challenge puts UD student on fast track to outwitting hackers

“Cryptography enables you to send secret code and hide information within a network to keep it secure,” Billy Bednar, a University of Delaware senior, told U.S. Sen. Tom Carper during a conference call Wednesday, July 18. 

Carper, who is chairman of the Senate Homeland Security and Governmental Affairs Committee, is working to help safeguard the nation’s cyber space. To accomplish this he will need to rely on today’s leading experts, but also ensure that future cyber sleuths currently in the pipeline have the proper training to meet emerging cyber challenges.

Microsoft and LEGO Education demonstrate development possibilities on Windows 8.1 with SentryBot

Through a shared commitment to STEM education, Microsoft and LEGO Education team up to create hands-on opportunities for the next generation to be inspired by and engage with technology in new ways.

SAN FRANCISCO — Ever wonder what it takes to inspire and prepare the next generation to fill the pipeline of science, technology, engineering and mathematics (STEM) jobs of the future? For Microsoft and LEGO, the answer is simple: Make STEM fun, accessible and engaging. At Microsoft’s recent developer conference, BUILD, Microsoft revealed the SentryBot — a small, yet powerful, robot featuring unique interactive scenarios only possible on the Windows platform. SentryBot demonstrates just how fun STEM can be regardless of your technical background. (more…)
