The SLAC team included several Berkeley Lab researchers. The discovery sparked the “November Revolution” – a period in the high-energy physics community marked by a series of rapid changes in the field.

Ensured Arsenic-Free Drinking Water
Tens of millions of people worldwide must obtain drinking water from sources with high arsenic levels, which are associated with increased cancer and other health risks. In the late 2000s, scientists invented ECAR, an inexpensive, effective electrochemical arsenic removal system that accelerates the rate of rust production and effectively removes arsenic below the regulatory standard of 10 parts per billion.

Caught Climate Change in the Act
For the first time, our scientists observed an increase in carbon dioxide’s greenhouse effect at the Earth’s surface. They attributed this upward trend to rising CO2 levels from fossil fuel emissions. The influence of atmospheric CO2 on the planet’s energy balance is well established, but this effect had not been experimentally confirmed outside the laboratory until now.

Pioneered the Use of Beam Therapies
Considered the birthplace of nuclear medicine, Berkeley Lab was a pioneer in using radioactive isotopes for medical treatments and imaging, and later for using the same powerful accelerators used in high-energy physics experiments to produce beams for medical treatment. Beams at the 184-Inch synchrocyclotron, now home to the Advanced Light Source, and later the Bevalac were used for medical treatments, and about 1,400 cancer patients were treated with beams at the Bevalac from the 1970s to the early 1990s.

Invented the Time Projection Chamber
The 1974 invention of a new type of particle detector, called a time projection chamber, or TPC, would provide a far more complete picture of particle collisions and interactions. The TPC design allowed the reconstruction of tens of thousands of subatomic particles from a single collision event, in 3-D and with greater accuracy than before. TPCs have found uses in a broad range of experiments – from reconstructing particle collisions to the hunt for dark matter particles.

Created a Global Database to Study the Carbon Cycle
Around the world, micrometeorological towers monitor carbon, water, and energy fluxes, which are measurements of how carbon dioxide, water vapor, and energy (heat) circulate between the soil, plants and atmosphere. And, Berkeley Lab computer scientists helped build the FLUXNET database to make this raw data publicly available for research.

Developed Mathematical Methods to Study Proteins 
To visualize the structure of proteins in their native environment, scientists can blast powerful X-ray beams at tiny volumes of proteins in solution. The resulting ‘diffraction patterns’ can then be interpreted to determine, or reconstruct, information about the protein’s molecular structure. This process is called fluctuation X-ray scattering, and Berkeley Lab researchers in 2015 developed a tool called “M-TIP” that can quickly determine the general structure of a sample in only a few minutes on a desktop computer.
