A recent study found that doctors rarely counsel smokers on quitting and advise only 23% of binge drinkers about their alcohol use. This can result in millions of smokers and binge drinkers not receiving health interventions.
A team of researchers found that young people use texting to widen their social networks and cope with demands from friends and parents. The report also highlights the 'gift-giving' properties of text messaging and its impact on industry plans for future mobile features.
Researchers from Cardiff University are conducting a £70,000 study to understand the advice needs of lone parents, who often struggle with income, housing, and childcare support. The study aims to identify barriers to access and advice for these families, shedding light on crucial issues that require attention.
Researchers have made significant progress on a new approach to batteries inspired by nanotechnology, which could power miniature devices and enhance portable electronics. The nano-battery approach seeks to replace traditional batteries with particles measured in billionths of a meter, potentially enhancing power storage and production.
A Toronto-based researcher has developed a system that uses acoustic signals to locate and orient devices, mimicking the navigation abilities of blind people. The technology could lead to improved communication devices such as cell phones or hand-held computers within five to ten years.
A study found that tailored telephone and mail reminders increased mammography screenings in women over 51. The combination of both methods led to more than twice as many follow-up screenings compared to usual care.
A new program, social problem-solving telephone partnerships (SPTP), uses phone calls to help family caregivers resolve challenges of caring for stroke survivors. The study found that caregivers who received SPTP improved significantly in their depression, emotional well-being, and mental health over four weeks.
This month's TLN discusses the role of genetic risk factors in sleep disorders, including narcolepsy and obstructive sleep apnoea syndrome. The study highlights the importance of investigating the effects of mobile phone use on human populations to better understand the complex mechanisms regulating sleep.
A study found that participants receiving automated, computer-based telephone intervention increased their level of physical activity after three months. However, the effectiveness dropped off by six months. The researchers suggest continued refinement of automated telephone interventions.
A long-term industry-funded rat study has found no statistically significant increases in any tumor type, including brain cancer, after exposure to radio frequency radiation at common cell phone signals. The study builds on earlier research and suggests the greatest hazard with cell-phones is driving a car while talking.
Researchers conducted a case-control study of 90 acoustic neuroma patients, but found no association with cellular telephone use. A slightly elevated risk was observed for infrequent users with 3+ years of cell phone use.
Researchers analyzed NOAA data on solar radio bursts to determine their impact on cellular communications. They found that bursts of 1,000 SFU occur on 10-20 days per year, causing disruptions every 40-80 days or several times a year.
A new study by the University of North Carolina at Chapel Hill found that only 3.1 percent of North Carolinians are talking on cell phones while driving at any given time. The prevalence rate varied by region, with higher rates in the Piedmont and lower rates in the mountains and coastal plain.
Researchers at Virginia Tech have developed a wireless broadband communications network for rapid deployment in disaster response and recovery efforts. The system uses the 28 GHz band to connect remote stations and provide GIS access, audio/video conferencing, and collaborative decision-making tools.
The NRL's Humvee-based communications system can provide two-way satellite commercial links and a private cellular telephone network. It can also handle streaming video, making it an essential tool for emergency response teams.
Michael H. Dickinson, a UC Berkeley professor, has been awarded the prestigious MacArthur Fellowship for his groundbreaking research on insect flight. His work has led to breakthroughs in understanding how insects fly and maneuver, with potential applications in search and rescue, environmental monitoring, and remote sensing.
A recent study by Carnegie Mellon University found that attending to a conversation significantly distracts the brain from processing complex visual information. Brain activity decreased by 29% when participants were simultaneously listening to a sentence and doing a complex visual task.
Two UK studies reveal that NHS Direct led to a significant decrease in Accident and Emergency department visits, with a substantial reduction in staff time needed. However, the rise in hospital switchboard calls indicates that more people need medical advice, highlighting the need for increased NHS Direct usage.
A study by Mayo Clinic researchers found that cellular telephones can interfere with the operation of external devices monitoring the heart and lungs. Interference occurred in 41% of devices, but was deemed clinically important only in 7.4%. Researchers recommend further testing to inform hospital policies.
A large case-control study found no association between cell phone usage and the development of primary brain cancer in a cohort of 891 participants. The study, published in JAMA, analyzed data from patients with primary brain cancer and controls without cancer, finding no correlation between cell phone use and brain cancer risk.
A recent study published in The Journal of the American Medical Association has found that handheld cellular telephone use is not associated with an increased risk of brain cancer. Researchers conducted a case-control study from 1994 to 1998 and analyzed data on 469 participants with primary brain cancer and 422 matched controls.
A study found that nearly half of e-mail users make fewer long-distance calls due to the convenience of online communication. E-mail excels in scheduling conflicts, while telephone is preferred for emotional expression and companionship.
The National Toxicology Program (NTP) will review testing recommendations for future studies on DNA-based therapies, dietary supplements, and occupational chemicals. The agenda includes discussion of DNA-derived vaccines, gene therapies, and radio frequency radiation emissions from cellular phones.
A new method devised by Purdue engineers can prevent disconnections for roaming cell phone users by allowing two adjacent cells to share channels, ensuring a continuity of service as a caller travels from one cell to the next. This technique could increase network efficiency by up to 60% and reduce disconnections by up to 100 times.
A nurse telephone consultation service can handle as many nighttime primary care calls as evening or weekend services, report researchers. The study found that handling calls alone did not increase patients attending daytime surgeries in the following days.
Researchers at Cornell University are working on bridging the gap between human dimensions and ultrasmall microchips. They aim to develop a dense array of connections to allow information exchange between large and small components.
Dennis L. Goeckel, an assistant professor of electrical engineering at the University of Massachusetts, has received a $200,000 grant from the National Science Foundation to continue his research on high-speed wireless communication. He uses mathematical models to optimize signals and improve reception quality.
The University of Kentucky Markey Cancer Center will operate the Mid-South Cancer Information Service, providing up-to-date scientific information on cancer prevention and services. The five-year contract is worth $7.15 million.
New gallium nitride transistors operate at microwave frequencies, delivering up to 100 times more power than current semiconductors. These devices will enable hundreds of low-orbit satellites serving cellular telephone users worldwide.
A University of North Carolina at Chapel Hill study suggests that nearly 30% of the US population attend church weekly, contradicting previous head counts. The research found that telephone polls like Gallup overestimate church attendance due to biased respondent demographics.
Researchers at Virginia Tech have developed a safer wireless antenna design called Safetenna. Safetenna eliminates transmission in the direction where the signal would be blocked by the user's head, reducing harmful absorption of power by the body. The new technology demonstrates improved performance with no trade-off on safety.
