Women's menstrual cycles temporarily synchronize with Moon cycles
An analysis of long-term menstrual cycle records kept by 22 women for up to 32 years shows that women with cycles lasting longer than 27 days intermittently synchronized with cycles that affect the intensity of moonlight and the moon's gravitational pull. This synchrony was lost as women aged and when they were exposed to artificial light at night. The (2021-01-27)

Extreme black holes have hair that can be combed
Black holes depend on only three parameters (mass, angular momentum, and charge), a uniqueness property known as the ''no-hair'' theorem. In a Letter published in the Physical Review D, researchers announce finding an exception: a class of black holes, known as extreme black holes, that has classical hair in the vaccuum Einstein theory. The newly discovered hair depends on how the black hole formed, thus violating the uniqueness, or ''no hair'' theorem. (2021-01-26)

Optimal information about the invisible
Laser beams can be used to precisely measure an object's position or velocity. Normally, a clear, unobstructed view of this object is required. Irregular environments scatter the light beam - but as it turns out, precisely this effect can be used to obtain optimum information in difficult situations. (2021-01-25)

Getting romantic at home wearing an EEG cap
Research into the neuronal basis of emotion processing has so far mostly taken place in the laboratory, i.e. in unrealistic conditions. Bochum-based biopsychologists have now studied couples in more natural conditions. Using electroencephalography (EEG), they recorded the brain activity of romantic couples at home while they cuddled, kissed or talked about happy memories together. The results confirmed the theory that positive emotions are mainly processed in the left half of the brain. (2021-01-13)

Rare star's giant gamma-ray burst GRB 204015A captured close to our home galaxy
Earth gets blasted by mild gamma ray bursts most days. But sometimes a giant flare like GRB 200415A arrives at our galaxy, sweeping along energy that dwarfs our sun. It erupted from a rare, powerful neutron star called a magnetar - giving new clues to GRB origins - and from relatively nearby. The extreme explosions from these bursts can disrupt mobile phone reception, and can also be messengers from the very early history of the universe. (2021-01-13)

Singing a tumor test song
Singing may be the next-generation, noninvasive approach to determining the health of a patient's thyroid. When a person sings, the vibrations create waves in the tissue near the vocal tract called shear waves. If a tumor is present in the thyroid, the elasticity of its surrounding tissue increases, stiffening, and causing the shear waves to accelerate. Using ultrasound imaging to measure these waves, researchers can determine the elasticity of the thyroid tissue. (2021-01-12)

This method might in future make it possible to track experimentally the formation and decay of quantum Efimov systems. (2020-12-23)

Controlling cardiac waves with light to better understand abnormally rapid heart rhythms
Over 300,000 people die each year in the US due to sudden cardiac death. In many cases, sudden cardiac death is caused by abnormally rapid heart rhythms called tachycardias, which means the heart cannot pump adequate blood to the body. In Chaos, researchers use mice to study tachycardias and find there are intrinsic mechanisms that exist in heart tissue that they hypothesize lead to the self-termination of rapid cardiac rhythm.
