"The Higgs Boson" - An Interview with Heather Gray, PhD of UC Berkeley and Lawrence Berkeley Labs

By Shoshana Harlem (MSS intern, Terra Linda High School)

Heather Gray is an Assistant Professor at UC Berkeley/Lawrence Berkeley Lab. Her main area of study is the Higgs Boson, but she also focuses on studying silicon pixel detectors and algorithms.

1. What made you want to study the Higgs Boson? 

I came to study physics somewhat by chance, but as soon as I heard about particle physics, it was immediately obvious to me that this is something that I find extremely interesting and wanted to study. When I finished my PhD, we were collecting lots of data and I wanted to look for the Higgs boson because it's an important particle and was the only particle missing from the Standard Model.

2. What are the best parts of your job?

 There are many great parts about my job. The privilege of being able to understand deep questions about how the universe works is probably the best. I also get to work with smart people from all over the world and to travel to interesting places.

3. What are the worst parts of your job?

Not much, but if you push me, I guess I'd have to say too many meetings.

4. What is the Higgs Boson?

Higgs Boson particle
The Higgs boson is a particle that is thought to be responsible for particle masses. It was first predicted back in the 1960s and discovered by my experiment (ATLAS) and another one (CMS) only in 2012. We collide protons traveling at close to the speed of light and destroy them to use that energy to produce Higgs bosons. The Higgs boson is very unstable and decays almost immediately to other particles in the Standard Model.

5. What current research are you working on?

Right now I'm working to study how the Higgs interacts with quarks. In the Standard Model, the Higgs is predicted to interact with all particles that have mass and for the strength of the interaction to be proportional to the particle mass. The quarks have a wide range of masses so this makes them particularly interesting to study to try to understand if this particle that we've discovered is the Higgs boson as predicted by the Standard Model.

All About Lysosomes

by Angel Zhou, Branson School

Lysosomes, discovered and named by Belgian biologist Christian de Duve, who eventually received the Nobel Prize in Medicine in 1974, are membrane-enclosed organelles that function as the digestive system of the cell, both degrading material taken up from outside the cell and digesting obsolete components of the cell itself. The membrane around a lysosome allows the digestive enzymes to work at the pH they require. In their simplest form, lysosomes are visualized as dense spherical vacuoles, but they can display considerable variation in size and shape as a result of differences in the materials that have been taken up for digestion. Lysosomes contain an array of enzymes capable of breaking down biological polymers, including proteins, nucleic acids, carbohydrates, and lipids.

The lysosome’s enzymes are synthesized in the rough endoplasmic reticulum. The enzymes are released from Golgi apparatus in small vesicles which ultimately fuse with acidic vesicles ca…

The Birth of the Universe, through Today's Telescopes

     A story is typically told from the beginning, but oftentimes the universe is an exception. As a society, time is measured in days and nights, hours, minutes, and seconds. But even more so, time is apparent to us through the peachy sunrise of dawn, the angry grumbles of an empty stomach at noon, and the fatigue that settles with the darkness of night. It's hard to imagine any of these things in relation to the universe, with its sleepless planets and nomadic asteroids, all swallowed up in an unimaginably large blanket of space. If the universe is a story, and all the galaxies, comets, and stars its characters, where does it all begin? 
     Luckily, scientists have already delved into the origins of the universe, and have resurfaced with new and exciting insights regarding these qu…

Green Homes and the Greenhouse Effect

   Climate change has integrated itself into our daily actions. It’s in the green recycle bins, marked with the immediately recognizable triangular arrow symbol, the paper versus plastic, the electric cars humming down the road and the grass-fed cows. Becoming environmentally-conscious has affected many communities, some more than others.      It’s still not enough. Ice caps are still making the news as they melt into the ocean, and this summer’s record-breaking temperatures have cast an ominous shadow onto the future. People are largely aware of this, but oftentimes brush the frantic cries of environmental scientists off. To many, global warming has faded into the background, a part of the ever-changing scenery and a doom so large and so distant there’s no point in actively searching for ways to slow it. ‘Going green’ is too unwieldy, too time-consuming, too costly or too much effort.
    However, global warming cannot be dismissed so easily. Ice caps…
