BUFFALO, N.Y. -- When a disaster's physical evidence is gone -- debris removed, shooter arrested, ashes cold -- the psychological effects of the disaster on emergency responders and civilians involved still may burn.
Emergency mental health, a field often overlooked in the chaos, is a vital component of any disaster response, but may not be well represented in emergency preparedness planning.
Guojun Liu has discovered a way to use nanotechnology to reduce friction in automobile engines and machines.
"The technology should be useful in a wide range of machineries other than automobile engines," says Dr. Liu, a professor in the Department of Chemistry and an expert in polymer synthesis. "If implemented industrially, this nanotechnology should help prolong machine life and improve energy efficiency."
Tropical Cyclone Atu had a brief but memorable life last week, and NASA's Atmospheric Infrared Sounder (AIRS) instrument that flies aboard NASA's Aqua satellite captured a day-by-day look at its growth and death.
WASHINGTON, March 1—The world's largest international conference onoptical communications will take place March 6-10 at the Los Angeles Convention Center. The Optical Fiber Communication Conference and Exposition/National Fiber Optic Engineers Conference (OFC/NFOEC) is the premier telecom meeting where experts from industry and academia share their results, experiences, and insights on the future of electronic and wireless communication and optical technologies. More than 10,000 attendees and an exhibit with 500 companies are expected.
CONFERENCE HIGHLIGHTS
A team of scientists led by John Badding, a professor of chemistry at Penn State University, has developed the very first optical fiber made with a core of zinc selenide -- a light-yellow compound that can be used as a semiconductor. The new class of optical fiber, which allows for a more effective and liberal manipulation of light, promises to open the door to more versatile laser-radar technology.
Scientists now have a better understanding of why spider silk fibers are so incredibly strong. Recent research, published by Cell Press on February 15th in Biophysical Journal, describes the architecture of silk fibers from the atomic level up and reveals new information about the molecular structure that underlies the amazing mechanical characteristics of this fascinating natural material.

A research group led by scientists from the University of Bristol has demonstrated the quantum operation of new components that will enable compact circuits for future photonic quantum computers.
Quantum computers, holding the great promise of tremendous computational power for particular tasks, have been the goal of worldwide efforts by scientists for several years. Tremendous advances have been made but there is still a long way to go.
A pioneering program by one of the world's largest cities to switch its vehicle fleet to clean fuel has not significantly improved harmful vehicle emissions in more than 5,000 vehicles – and worsened some vehicles' climate impacts – a new University of British Columbia study finds.
The study – which explores the impacts of New Delhi, India's 2003 conversion of 90,000 buses, taxis and auto-rickshaws to compressed natural gas (CNG), a well-known "clean" fuel – provides crucial information for other cities considering similar projects.
A spongy substance that could be mistaken for packing material has the nanotechnology world buzzing.
University of Central Florida Associate Professor Lei Zhai and postdoctoral associate Jianhua Zou have engineered the world's lightest carbon material in such a way that it could be used to detect pollutants and toxic substances, improve robotic surgery techniques and store energy more efficiently.
The new material belongs to the family of the lightest solid, also known by its technical name of aerogel or its common nickname of "frozen smoke."
New Haven, Conn.—Imagine a material that's stronger than steel, but just as versatile as plastic, able to take on a seemingly endless variety of forms. For decades, materials scientists have been trying to come up with just such an ideal substance, one that could be molded into complex shapes with the same ease and low expense as plastic but without sacrificing the strength and durability of metal.
Only in very few life phases do individuals face as many life transitions in such a short time as young adults at the age of 19-30. The transition from adolescence to adulthood is characterised by frequent changes in status or social roles, such as leaving the parental home, starting a career, entering into working life, forming a partnership and becoming a parent. Assuming civic and social responsibility is also an integral part of the lives of young adults at this particular life phase.
Researchers at the Georgia Tech Research Institute (GTRI) are developing a solid composite material to help cool small, powerful microelectronics used in defense systems. The material, composed of silver and diamond, promises an exceptional degree of thermal conductivity compared to materials currently used for this application.
LA JOLLA, Calif., March 1, 2011 – When patients receive a bone marrow transplant, they are getting a new population of hematopoietic stem cells. Fresh stem cells are needed when a patient is low on red blood cells, as in anemia, or white blood cells, which can be caused by cancer or even cancer treatments such as irradiation or chemotherapy. The problem is that a bone marrow transplant might not succeed because the transplanted stem cells don't live long enough or because they proliferate too well, leading to leukemia.
Computational scientists have a new weapon at their disposal.
On February 1, the Electronic Simulation Monitoring (eSiMon) Dashboard version 1.0 was released to the public, allowing scientists to monitor and analyze their simulations in real-time.
