DECam confirms that early-universe quasar neighborhoods are indeed cluttered

A new study using the Dark Energy Camera has found that early-universe quasars have surrounding companion galaxies within a distance of 15 million light-years, which is consistent with expectations. However, the team also discovered that there are no companion galaxies within 60 million light-years of the quasar.

New study raises questions about validity of standard model of solar flares

A recent study tested the standard model of solar flares by comparing computer simulations with observational data from the McMath-Pierce telescope. The researchers found a significant delay in the paired chromospheric sources, which challenges the current energy transport mechanism by electron beam. This delay suggests that other fact...

Dream discovery: Melatonin's key role in REM sleep revealed

Researchers have identified the melatonin MT1 receptor as a crucial regulator of REM sleep, which is essential for dreaming, memory consolidation, and emotional regulation. The discovery holds significant clinical potential for developing targeted treatments to improve the quality of life for patients affected by debilitating diseases.

European capacity for antibiotic R&D requires long-term funding

The European capacity for antibiotic research and development requires sustained investment to combat growing resistance. Collaboration and risk-sharing can help keep companies in anti-infective drug development, as a temporary funding strategy may lead to lost efforts.

How a believer becomes a skeptic

A study of mostly climate science believers found that even the strongest believers felt skeptical claims were more true when encountered a second time. This effect, known as 'truthiness,' can lead people to perceive false claims as valid if repeated enough times.

Study of former NFL players finds 1 in 3 believe they have CTE

A new study of nearly 2,000 former NFL players shows that about one-third believe they have chronic traumatic encephalopathy (CTE), a condition linked to repeated head trauma. Players who believed they had CTE reported more cognitive problems and higher rates of treatable conditions such as depression and low testosterone.
