Researchers found modest, yet reliable long-term links between early childhood household smoke exposure and self-reported antisocial behavior in early adolescence.
A new article looks at the potential benefits of a Billion Ton Bioeconomy, a vision to enable a sustainable market for producing and converting a billion tons of US biomass to bio-based energy, fuels, and products by 2030.
A new article summarizes the findings of 16 studies that illustrate how natural regeneration of forests, a low-cost alternative to tree planting, can contribute significantly to forest landscape restoration in tropical regions.
Very little is known about what happens to oil in the ocean after an oil spill and what happens to it once a chemical dispersant has been applied. New research summarizes what is known and what important knowledge gaps remain.
New research found a high prevalence of military sexual trauma (MST) among transgender veterans and an association between the experience of MST and certain mental health conditions.
Contaminants called polycyclic aromatic hydrocarbons from oil spills can be toxic to wildlife, especially when in combination with ultraviolet radiation from the sun. New research on species native to the Gulf of Mexico indicates that, compared with oil exposure alone, co-exposure to oil and natural sunlight reduces survival rates of fish that spend time close to the surface in their larval stage.
Vitamin D supplementation improved symptoms of autism in a recent trial.
Scientists have recently discovered a new bohaiornithid bird specimen from the Early Cretaceous Period of China with remarkably preserved feathers. Bohaiornithid birds belonged to enantiornithes, a group of avian dinosaurs that lived millions of years ago.
Within the criminal justice community, an approach to community supervision known as Honest Opportunity Probation with Enforcement (HOPE) has generated widespread enthusiasm and praise as a way to reduce substance use, violations, new arrests, and revocations to prison, while also leading to significant cost savings for local justice systems. A new study casts doubts on the benefits of HOPE over probation as usual (PAU), however.
Sex-Related Differences in the Brain May Affect Pathways to Substance Abuse in Adolescents with Bipolar Disorder
A new study has found that adolescents suffering from bipolar disorder are more likely to develop substance use disorders if they have lower gray matter volume in the brain, a clue that can help in the design of better methods for early detection and more targeted prevention and treatment.
In a study of 736 asthma patients in Singapore, good asthma control resulted in a saving of S$65 (US$48) per physician visit. Compared with an average cost of S$214 (US$158) per visit, this reduction represents a cost saving of 30% versus suboptimally controlled asthma.
Following decades of clinical research largely excluding females, scientists are finding that there are large differences in men and women that go well beyond their reproductive systems. Now, the Journal of Neuroscience Research is dedicating an issue entirely to sex differences at all levels of the brain, from the genetic and epigenetic level, to the synaptic, cellular, and systems levels.
New research suggests that physical fitness, body mass index (BMI), IQ, and stress resilience in young adulthood may have effects on the risk of developing amyotrophic lateral sclerosis (ALS), or Lou Gehrig’s disease.
In a population-based Canadian study of children with epilepsy, each of whom had access to universal health care, those from poor families had the same medical course and remission rate as their wealthier counterparts, but they had a less favorable social outcome as adults.
In a study of healthy postmenopausal women, reproductive life events related to sex hormones, including earlier age at menarche, later age at last pregnancy, length of reproductive period, and use of oral contraceptives were positively related to aspects of cognition in later life.
Some animals, such as the axolotl salamander, have the ability to generate large numbers of eggs—or oocytes—throughout life. Investigators who recently conducted detailed analyses of the axolotl provide insights on the mechanisms of ovarian regeneration that could assist regenerative medicine in treating pre-mature ovarian failure and reduced fertility in humans.
A new study found that speech difficulties are linked with difficulties in learning to read when children first start school, but these effects are no longer apparent at 8 years of age.
Recently, in the UK, the National Institute for Health and Care Excellence (NICE) outlined criteria that should trigger primary care clinicians to refer patients with suspected colorectal cancer to see an oncologist. A new analysis of 1981 patients with lower gastrointestinal symptoms indicates that using these criteria, physicians would miss nearly 20% of colorectal cancers.
An increase in muscle size with exercise may not be directly related to an increase in muscle strength, according to a recent analysis of the literature.
Researchers are exploring ways to help clinicians and investigators use and share routinely collected medical data (such as information in electronic health records) to improve care and advance clinical research.
