Shedding light on dark matter

A team of researchers, led by Hagit Shatkay, is developing computational methods to accelerate discovery in astroparticle physics, a crucial step towards understanding dark matter. By analyzing noisy sensor data from an underground experiment, the team aims to detect and identify dark-matter particles.

New hunt for dark matter

Researchers propose using gravitational-wave observatories to detect axions, which could be a type of dark matter. Axions are predicted to modulate light polarization and can be detected with existing laser-based experiments, offering a cost-effective solution to the hunt for dark matter.

Tracking down dark matter

Researchers at Mainz University have developed a new method to detect axions, a type of dark matter, using the Cosmic Axion Spin Precession Experiment (CASPEr) program. By exploiting nuclear magnetic resonance and sophisticated shielding, the team aims to identify spin changes caused by dark matter, which can be distinguished from thos...

The smell of dark chocolate, demystified

Researchers identified volatile compounds contributing to dark chocolate's distinctive aroma, including β-ionone and other essential components. By quantifying these substances using stable isotope dilution analysis, the team successfully reconstructed the scents of two dark chocolates with remarkable accuracy.

Researchers observe slowest atom decay ever measured

Researchers at the University of Zurich's XENON1T detector have observed the slowest atom decay ever measured, with a half-life time over a trillion times longer than the age of the universe. This rare process, called double electron capture, was detected for the first time and has implications for understanding dark matter.

Weapons trade reveals a darker side to dark web

Research published in Deviant Behavior found that the dark web is a hub for anonymous handgun sales, with 64% of products advertised being handguns. The study sheds light on a niche market where buyers can circumvent stricter gun laws, highlighting the need for further investigations and potential regulation.

Physicists constrain dark matter

Researchers have constrained a theoretical model of dark matter particles using data from Earth-based radio telescopes. The study found that ultralight particles interact weakly with photons, making them hard to study, but also revealed a constraint on the available models describing dark matter composition.

Hubble captures birth of giant storm on Neptune

A team of planetary scientists used Hubble images to track the growth of a new Great Dark Spot on Neptune, finding that dark spots originate deeper in the planet's atmosphere than previously thought. The study also revealed that these storms occur with a frequency of every four to six years and last up to six years.

Dark matter on the move

Scientists have discovered that dark matter can be heated up and pushed outwards due to star formation in galaxies. This phenomenon, known as 'dark matter heating', has been observed in 16 dwarf galaxies with varying star formation histories.

Faint starlight in Hubble images reveals distribution of dark matter

Astronomers have developed a revolutionary method to detect dark matter using faint starlight in Hubble images. The technique accurately studies the distribution of dark matter and has been confirmed in galaxy clusters. Future studies will survey more clusters and analyze additional data with the James Webb Space Telescope.

Rice U. lab finds evidence of matter-matter coupling

Researchers at Rice University have discovered the first example of Dicke cooperativity in a matter-matter system, which could lead to faster information processing and lower power consumption. The discovery uses a magnetic field to prompt cooperativity among spins within a crystalline compound made primarily of iron and erbium.

No sign of symmetrons

Researchers at TU Wien use the PF2 ultra-cold neutron source to test the existence of symmetrons, a theory that could explain dark matter. The experiment excludes a broad range of parameter values, but the team is cautious and seeks further measurements or discoveries.
