The National Institute of Standards and Technology (NIST) has released its final report on its study of the June 18, 2007, fire at the Sofa Super Store in Charleston, S.C., that trapped and killed nine firefighters, the highest number of firefighter deaths in a single event since 9/11. The final report is strengthened by clarifications and supplemental text based on comments provided by organizations and individuals in response to the draft report of the study, released for public comment on Oct. 28, 2010.

It's increasingly difficult to keep up with all the vulnerabilities present in today's highly complex operating systems and applications. Attackers constantly search for and exploit these vulnerabilities to commit identity fraud, intellectual property theft and other attacks. The National Institute of Standards and Technology (NIST) has released two updated publications that help organizations to find and manage vulnerabilities more effectively, by standardizing the way vulnerabilities are identified, prioritized and reported.
Few specimens inspire greater thrills among fossil collectors than a complete trilobite. These ancient arthropods – relatives of lobsters, spiders and insects – went extinct more than 250 million years ago, but are sometimes found in beautifully preserved condition. In rare instances, an entire population of trilobites is found fossilized together. Carlton E. Brett finds evidence for ancient environment and behavior in these mass graves.
A promising new approach for checking the accuracy of measurements of hazardous indoor air pollutants may soon be ready for prime time, report researchers from the National Institute of Standards and Technology (NIST) and Virginia Tech.* The measurement tool, a reference sample for volatile organic compounds (VOCs), would be a boon to testers of indoor air quality and to manufacturers of paints, rugs, cleaners and other building products.
A recent study from North Carolina State University shows that while the number of visits to state parks across the country has grown, fund support for park operations has been significantly reduced. The reduction in funding during a time of park growth endangers the more than $20 billion in economic impact that state parks have on the nation's economy.
Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley have learned to control the quantum pathways determining how light scatters in graphene. Controlled scattering provides a new tool for the study of this unique material – graphene is a single sheet of carbon just one atom thick – and may point to practical applications for controlling light and electronic states in graphene nanodevices.
Clinical depression can exacerbate the symptoms of knee arthritis beyond what is evident on X-rays, according to a new study from the Journal of Bone and Joint Surgery (JBJS). Patients with mild to moderate knee arthritis are especially affected by depression, the study notes.
There are considerable differences in the sickness absence between women and men. In the first half of 2008, 14.5 million days of sickness absence were paid out to women and 9.2 million to men. This is not a specific Swedish phenomenon but characterizes countries with a large share of women on the labour market. While men and women have about the same level of sickness absence before the birth of the first child, the sickness absence of women is twice as high after the birth of the first child and up until 15 years after that.
The Australian Stem Cell Centre (ASCC) has submitted its recommendations to the independent committee reviewing the Australian legislation governing the use of human embryos in research. The ASCC's submission makes a series of recommendations in support of the current regulatory framework and the ongoing requirement for Australian scientists to be able to apply for a licence to derive new human embryonic stem cells for use in research.
In summary the ASCC recommends that:
- Researchers believe that an early age at first drink (AFD) may lead to greater stress-induced drinking.
- A new study examines interactions between AFD and stressful life events on drinking during young adulthood.
- Findings indicate a strong link between an early AFD and later heavy drinking when confronted by a high load of stressful life events.
Minneapolis, MN —March 15, 2011—A new study from the Journal of Marriage and Family shows that contrary to popular anxieties about slacker young adults who refuse to grow up, or indulgent parents who stifle their adult children's development by continuing to support them, there is evidence that parental assistance in early adulthood promotes progress toward autonomy and self-reliance.
BEER-SHEVA, ISRAEL, March 15, 2011– Ben-Gurion University of the Negev (BGU) researchers have shown that a significant number of patients with benign prostate enlargement (BPE) may have Obstructive Sleep Apnea (OSA), which may be the reason for their night awakenings and urination.
This study compared men between the ages of 55 and 75 who were randomly sampled from primary care clinics, diagnosed with BPE and reported nocturia at least once nightly. The comparison control group had no BPE and one or no nocturia episodes per night.
University Park, Pa. -- Children of immigrants are more likely to live in households headed by two married parents than children of natives in their respective ethnic groups, according to Penn State sociologists.
This intact family structure may offer immigrant children economic and social advantages that help them adapt to their new country, according to Nancy Landale, professor, sociology and demography.
WASHINGTON — Good travel data are essential to measure and monitor the performance of the U.S. transportation system and to help guide policy choices and investments in transportation infrastructure, says a new report from the National Research Council that calls for the creation of a national travel data program. Current data are inadequate to support decision making in the transportation sector.

The massive marketing campaigns launched by publishing houses at the start of the academic year can cause people bound to suffer obsessive-compulsive disorder to develop this pathology before. The fact is that collecting articles without control is a symptom of this serious psychological disorder –one of which most known variants is Diogenes syndrom– and of shopping addiction. These are two mental disorders affecting approximately 12% of the population.
