We show that at the energies and luminosities soon to be attained with antiproton—proton colliding beams, the cross section for antiquark—quark annihilation, leading to production of a gluon jet in association with a Z 0 at large angles, is measurable and has a magnitude, energy dependence,...
“If we figure out how to harness this effectively and efficiently, this is it. This is the end. This is the solution,” an expert tells us.
In the early days of X-ray science, a lot of doctors would expose patients and themselves to the beams for long periods of time. Eventually, doctors and patients started developing radiation sickness, and the medical community knew something was wrong. The problem is that X-rays are a form...

2) IMRT: Intensity-modulated radiotherapy helps to specifically apply radiation beams to tumor cells by manipulating photon and proton beams to the shape of the tumor. 3) Brachytherapy: It is a type of internal therapy that inserts a radioactive implant that releases a high dose of radiation ...
While cinderblock walls are great for stopping x-rays from escaping your lab, they are also great for reflecting them back at you! It’s better to have them escape rather than to have them bounce around. When possible, be sure to either point your x-ray beams down to the earth or up...
The COVID-19 pandemic and subsequent lockdowns have led to a record crash in emissions. But it will be emission levels during the recovery—in the months and years after the pandemic recedes—that matter most for how global warming plays out, according t
Atom smashers or particle accelerators are machines that utilize electro-magnetic fields to speed up the movement of atomic particles after two energy beams collide with each other.Answer and Explanation: There are several types of particle accelerators. For example, two energy particle beams come ...
Cells are the building blocks of life. To gain more insight into the different cell types and theirmolecular processes, scientists use a technology called single-cell RNA sequencing (scRNA-seq). This involves measuring the number of mRNA molecules generated by activegenesin the individual cells. ...
In the guard cells of flowering plants, the products of certain key signalling genes haveunique propertiesor are found in much higher concentrations than in the surrounding leaf cells. The specificity of these genes is likely important for controlling the hydraulic pressure in the guard cells. ...
