Hair can be dyed at home or at a salon. Is one safer than the other?

(DOE/Thomas Jefferson National Accelerator Facility) The Electron-Ion Collider Center at the Department of Energy's Thomas Jefferson National Accelerator Facility (EIC Center at Jefferson Lab) has announced the winners o...

Targeted deep brain stimulation may help treat obsessive-compulsive disorder.

Dopamine neurons in the brain regulate internal processes of economic decision making, evaluating available options, and identifying the most preferable outcome.

What makes ships mysteriously slow down or even stop as they travel, even though their engines are working properly? This was first observed in 1893 and was described experimentally in 1904 without all the secrets of thi...

An international team led by physicists from the Ludwig-Maximilians Universitaet (LMU) in Munich realized a novel genuine time-dependent topological system with ultracold atoms in periodically-driven optical honeycomb la...

(Forschungsverbund Berlin) Optical amplifiers based on chirped pulse amplification (CPA) are used to generate high intensity pulses. In the CPA scheme, a weak temporally stretched seed pulse is amplified to high energy i...

Scientists have urged people to eat less meat and dairy after finding livestock farming singlehandedly exceeds "planetary boundaries" for nitrogen pollution

Researchers directly measured oxygen levels in an intact brain and correlated it with neural activity. During normal activity, only 50% of oxygen is used for neural activity, the remaining 50% is required for glial cells...

Owners who are encouraging increased their dog's showing effort for finding a toy, but decreased their showing accuracy.

Dropping the level of the IL-33 immune molecule increased the number of synapses in the brain. In older mice, ramping up IL-33 helped push the number of new synapses toward a more youthful state.

It images single atoms. It maps atomic-scale hills and valleys on metal and insulating surfaces. And it records the flow of current across atom-thin materials subject to giant magnetic fields. Scientists at the National ...

Researchers from the Facility for Rare Isotope Beams (FRIB) Laboratory at Michigan State University (MSU) have taken a major step toward a theoretical first-principles description of neutrinoless double-beta decay. Obser...

Whether it's on top of a self-driving car or embedded inside the latest gadget, Light Detection and Ranging (lidar) systems will likely play an important role in our technological future, enabling vehicles to 'see' in re...

Micro-saccades, or tiny eye movements, can be used as an index of our ability to anticipate relevant information in the environment, independent of the information's sensory modality.

The treatment contains two antibodies shown to help neutralize the virus.

By tuning the direction of the external magnetic field with respect to the crystallographic axis of the silicon wafer, an improvement of spin lifetime (relaxation time) by over two orders of magnitude was reported in sil...

The infralimbic system priorities caring for offspring and promotes maternal behavior in rats.

The ‘quasiparticles’ defy the categories of ordinary particles and herald a potential way to build quantum computers --

As many diseases, including neurodegenerative diseases such as Alzheimer's, have been linked to the defective functioning of motor proteins in cell transport systems, understanding the intricacies of how motor proteins w...

Power-scalable ultrafast laser sources in the midwave-infrared (MWIR) are a key element for basic research and applications in material processing and medicine. Optical amplifiers based on chirped pulse amplification (CP...

The chances of having asthma are three times higher in teenagers who go to bed late at night compared to those who sleep earlier. The risk of allergic rhinitis is two times higher for late sleepers. Researchers say they ...
