Duplicate DNA a hallmark of tick genome

Researchers have sequenced the Ixodes scapularis tick genome, which supports redundancy and has implications for disrupting disease transmission. The large genome includes duplicative elements and hormones regulating development, suggesting potential for developing a 'birth-control pill' to eradicate ticks.

It doesn't 'get better' for some bullied LGBT youths

A new Northwestern University study found that about a third of adolescents experience severe and ongoing bullying, which can lead to major depression and post-traumatic stress disorder (PTSD). The study also highlighted the importance of addressing these patterns in schools through policies and programs.

Common colds at school a primary driver of asthma hospitalizations for children

A new study confirms that school reopenings are a primary driver of asthma exacerbations in children, with cold viruses being largely to blame. The research found a significant correlation between the timing of school starts and hospitalizations, highlighting the importance of preventive measures during peak viral transmission periods.

Circadian misalignment helps explain higher risk for cardiovascular disease

A new study from Brigham and Women's Hospital found that circadian misalignment increases blood pressure and inflammatory markers in healthy adults. Researchers measured these factors in 14 participants during two eight-day stays in the sleep laboratory, one with circadian alignment and the other with misalignment.

Nature's mirror -- the code for chirality

Researchers discovered that biological molecules can change the shape of minerals by controlling how they link together, a process that could lead to the development of new drugs and synthetic materials. The study's findings shed light on the importance of chirality in drug development, as seen in the devastating Thalidomide tragedy.

ACP publishes depression recommendations; news from Annals of Internal Medicine

The American College of Physicians recommends using either cognitive behavioral therapy or second-generation antidepressants to treat adults with major depressive disorder. Both treatments are found to be similarly effective for treating depression, and physicians should consider a discussion with the patient about treatment effects, a...

Stanford study finds possible new jet-lag treatment

Researchers at Stanford University School of Medicine developed a possible new method for preventing jet lag by exposing people to short flashes of light while they sleep. The study found that this method can speed up the brain's adjustment to time changes, reducing the delay in onset of sleepiness.

AAAS Scientific Freedom and Responsibility Award goes to psychologist Jean Maria Arrigo

Jean Maria Arrigo received the AAAS Scientific Freedom and Responsibility Award for her tireless efforts to expose the American Psychological Association's (APA) complicity in torture and abuse. She stood against the APA's Task Force on Psychological Ethics and National Security, which justified coercive interrogations, and instead adv...

Newer pain management strategies can lead to quicker, shorter recovery after TKRs

A new literature review suggests that a team-based care approach, combining newer pain management strategies, is key to maximizing patient outcomes after total knee replacement (TKR) procedures. Multimodal protocols, including regional anesthesia and intra-operative pain injections, have been shown to lower patient pain severity rating...

Terrestrial laser scanning in California

Researchers evaluated the performance of Riegl Z620i and LPM-800HA terrestrial laser scanners on characterizing natural surfaces. They established a procedure to test componential uncertainty budgets and demonstrated the relationship between reference network uncertainty and imaged surface repeatability.
