Here are the best laser and inkjet printers for small businesses, a selection of fast, reliable multifunction printers durable enough for busy office......»»
Apple strong passwords aren’t entirely random, but are cleverly designed
Whenever an Apple device generates a strong password for you, the structure of those secure passwords isn’t entirely random. Instead, Apple created rules specifically designed to make them easier to type if you ever have to do that manually, and.....»»
First results from the Axion Dark-Matter Birefringent Cavity experiment establish a new technique for axion search
Researchers at MIT recently published the first results of an experiment aimed at searching for axion dark matter by probing the axion-induced birefringence of electromagnetic waves. While these findings, published in Physical Review Letters, did not.....»»

New findings using data from NASA's IXPE (Imaging X-ray Polarimetry Explorer) mission offer unprecedented insight into the shape and nature of a structure important to black holes called a corona. The findings are published in The Astrophysical Journ.....»»
Cryo-electron microscopy sheds light on endothelin signaling mechanisms
Endothelin is a peptide hormone known for its vasoconstrictive effects. Researchers at University of Tsukuba used cryo-electron microscopy to examine the complex structure of the endothelin receptor and G protein, which are crucial for signal transdu.....»»
New technique enhances precision in measuring short-lived atomic nuclei
Researchers at the Heavy Ion Research Facility in Lanzhou (HIRFL-CSR) have introduced a technique, Tune-IMS, designed to improve the precision of isochronous mass spectrometry (IMS) in measuring short-lived atomic nuclei. The development offers refin.....»»
Leap Seconds May Be Abandoned by the World’s Timekeepers
We have been adding “leap seconds” to time kept by our atomic clocks, but soon we may have to subtract one. Are the tiny adjustments worth the bother?.....»»
Genome sequencing could unlock answers to yellow jacket behavior
The most recognizable yellow jacket at Georgia Tech is made of fabric and foam, but Professor Mike Goodisman and a team of researchers revealed a far more complex cellular structure by successfully sequencing the genome of two local species of yellow.....»»
The neutron lifetime problem—and its possible solution
Neutrons are among the basic building blocks of matter. As long as they are part of a stable atomic nucleus, they can stay there for arbitrary periods of time. However, the situation is different for free neutrons: They decay—after about 15 minutes.....»»
First coherent picture of an atomic nucleus made of quarks and gluons
The atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to reproduce all the properties of atomic nuclei hitherto observ.....»»
