Cooked ham with a 39 day shelf life

A team of scientists has found a reliable and cost-effective method to extend the shelf life of cooked ham to 39 days by using a protective culture of Lactobacillus sakei. The treatment resulted in a more acceptably taste, texture, and overall quality compared to conventionally preserved ham.

Study documents rapid increase in youth bipolar disorder diagnoses

A study published in Archives of General Psychiatry found a substantial increase in office-based visit diagnoses for bipolar disorder among youth from 1994 to 2003. This growth was accompanied by rising prescription rates for mood stabilizers, antipsychotics, and antidepressants.

Depression in women with migraine linked to childhood abuse

Women with migraine who suffered childhood abuse were more likely to experience depression than those without abuse. The study found a significant association between childhood abuse and depression in women with migraine, suggesting that neurobiological systems may be altered by adverse experiences.

Smokers are more likely to develop dementia

A recent study published in Neurology found that smokers are 50% more likely to develop dementia than nonsmokers or past smokers. The study suggests that smoking increases the risk of dementia through mechanisms such as oxidative stress, which can damage cells in blood vessels and lead to hardening of the arteries.

Mice stressed in simulated weightlessness show organ atrophy

Rutgers researchers found that osteopontin-dependent changes in thymus and spleen lead to organ atrophy in mice stressed under simulated weightlessness. This study demonstrates the critical role of OPN in human diseases such as cancer, multiple sclerosis, and autoimmune responses.

Pop stars more than twice as likely to die an early death

A study of over 1050 North American and European musicians found that they are more than twice as likely to die an early death compared to the general population. Long-term drug or alcohol problems accounted for nearly one in four deaths, with some stars continuing to experience higher death rates even 25 years after achieving fame.

Genome study shines light on genetic link to height

A genome-wide association study has identified a genetic variant associated with human height, revealing the first consistent link between genes and height. The HMGA2 gene variation adds about half centimeter in height for one copy and almost full centimeter for two copies.

Princeton engineers develop low-cost recipe for patterning microchips

Researchers at Princeton University have invented a new process called fracture-induced structuring that enables the self-formation of periodic lines, or gratings, separated by as few as 60 nanometers. This technique uses a thin polymer film and is simpler and faster than traditional methods, making it economically feasible for large-s...

Lettuce, leafy greens and E. coli

Year-round consumption of fresh leafy greens like lettuce poses challenges due to increased risk of E. coli contamination from field sources. New methods, including harvesting mowers and triple washing, are being used to address this issue.

Passive smoking increases sleep disturbance among pregnant women

Pregnant women exposed to passive smoking experience sleep disturbances, including subjective insufficient sleep, difficulty initiating sleep, short sleep duration, and snoring. The study also found that pregnant women who smoke experienced similar sleep issues, as well as excessive daytime sleepiness and early morning awakening.

Work time is the largest influence to the duration of a person's sleep

A study published in the SLEEP journal found that work time has the largest reciprocal relationship to sleep time, with respondents working longer hours sleeping less. The study analyzed data from over 47,000 participants and found that travel time was also an unexpected factor affecting sleep.

Adolescents' use of cell phones after bedtime contributes to poor sleep

A study published in SLEEP found that adolescents who used their cell phones after bedtime were more likely to experience tiredness the next day. The researchers, led by Jan Van den Bulck, discovered that frequent phone use increased the risk of tiredness, with those using their phones daily being up to 5 times more likely to feel tired.

Study identifies warning signs of pregnancy danger

A study by Temple University researcher Kathleen Black identifies warning signs of pregnancy-induced hypertension, including increased stress levels, which can indicate worsening conditions. Women experiencing headaches, dizziness, frequent vomiting and malaise should call their physician immediately.

Radiation and drug combo helps boost efficacy of lung cancer treatment

Researchers at UT Southwestern Medical Center have found that combining radiation therapy with the drug bavituximab significantly improves the effectiveness of lung cancer treatment. The drug targets tumor blood vessels by selectively binding to exposed phospholipids, signaling white blood cells to attack and destroy them.

Anker Laptop Power Bank 25,000mAh (Triple 100W USB-C) keeps Macs, tablets, and meters powered during extended observing runs and remote surveys.

Two studies published in the Lancet

COPD is a leading cause of morbidity and mortality globally, with smoking being a primary risk factor. The International Burden of Lung Disease (BOLD) Study found that eastern Kentucky had one of the highest rates of COPD in the world.

Lack of sleep among new school-goers leads to behavioral, cognitive problems

A study published by the American Academy of Sleep Medicine found that children who get little sleep are more likely to have behavioral and cognitive problems in the classroom. The research identified four developmental sleep duration patterns, with short persistent sleepers showing significant impairments in cognitive performance.

Melanoma drug revs immune cells but cancer cells ignore it

Researchers found that an important melanoma treatment has little effect on cancer cells themselves, but instead boosts immune system cells. The study highlights the need to develop ways to make melanoma cells more vulnerable to the drug or overcome the block within cells that prevents them from responding.
