Phys.org / Gravitational wave detectors can now 'autotune' signals to harmonize the heavens

Gravitational wave researchers working on the world's most sensitive scientific instruments have found a way to tune their detectors using a process akin to the pitch-correction used in music production.

Phys.org / Gravitational waves from colliding black holes may allow detection of dark matter

Dark matter is thought to make up most of the matter in the universe, but the only way it interacts with its surroundings is through gravity. If two colliding black holes spiral through a dense region of dark matter and merge, ...

Phys.org / Largest-ever survey of physicists puts Standard Model of cosmology under scrutiny

The largest-ever survey of physicists from around the world—released today—shows a distinct lack of consensus across many of physics's most important questions, from the nature of black holes and dark matter, to the still-incomplete ...

Phys.org / 80 years after the Trinity nuclear test, scientists identify new molecule-trapping crystal formed in the blast

Matter behaves strangely under extreme conditions, and often, remnants of these behaviors are left behind even when conditions return to normal. The Trinity nuclear test in 1945 left behind such remnants, and now, 80 years ...

Phys.org / Old newspapers track porpoise populations across the Baltic Sea

Harbor porpoises were once found across a much wider area of the Baltic Sea than they are today, including regions where they are now rare or absent. This is shown in a new study that uses centuries-old Swedish newspapers ...

Phys.org / Swapping molecular building blocks one by one reveals how receptors tell adrenaline from dopamine

Different receptors respond to different neurotransmitters or hormones, such as adrenaline involved in the fight-or-flight response, or dopamine linked to reward and motivation. Both the receptors themselves and the substances ...

Phys.org / Engineered exosomes reverse sleep deprivation brain damage in mice

Sleep is a vital physiological process that allows humans and other animals to restore both the mind and body, while also consolidating memories, clearing out toxins and regulating their metabolism. Several past studies showed ...

Phys.org / TIME instrument unlocks faint signals from early galaxies across vast stretches of sky

Cornell astronomers are deploying a new instrument that grants them, for the first time, a better view of the universe's earliest galaxies, which can't be observed individually with traditional ground- or space-based telescopes.
