These techniques fell into four main domains: pain reduction, intimacy and relationship enhancement, desire and arousal enhancement, and emotional coping.

Clearing mangroves makes ‘muddification’ worse

A new study found that removing mangroves in New Zealand's estuaries actually increases mud build-up, as these coastal trees and shrubs trap sediment efficiently. This highlights the need for sustainable land use upstream to address the root cause of the issue, rather than focusing solely on mangrove removal.

The system, which includes parachutes and SD cards, proved essential to the mission's success and has been tested for use in future science missions.

Texas A&M professor published in leading history journal

Dr. Sonia Hernández's recent publication in the Journal of American History explores the complex histories of violence, gender, and power dynamics along the US-Mexican border region from 1900-1913. Her research centers on the testimonies of Mexican-origin women, shedding light on complicated gendered negotiations with state agents.

Study uncovers mediators of persistent HIV viremia

Researchers found large reservoirs of proviruses with mutations that help them evade detection, leading to low levels of residual viremia in individuals with HIV. Altered gene expression patterns also contributed to dampened immune responses and increased survival of infected cells.

Study sheds light on how Earth cycles fossil carbon

Researchers use rhenium as a proxy for carbon to quantify the rate of fossil carbon dioxide release into the atmosphere. The study found that high rates of carbon breakdown persist from mountaintop to floodplain, offering valuable insights into the planet's history and response to climate challenges.

When languages collide, which survives?

Researchers found that language coexistence is influenced by interaction between communities with opposing language preferences. Individual preferences play a pivotal role in language dynamics, sometimes overcoming social prestige.
