From Big Think: Is it true, what goes up must come down? Don Lincoln explores the ALPHA collaboration’s use of CERN’s Antimatter Factory to test if antimatter might experience gravity in a manner opposite of ordinary matter. The conclusion: antimatter does not fall upward.

Results from the ALPHA experiment confirm that matter and antimatter react to gravity in a similar way.

From Popular Science: A new observatory under construction in China—the Jiangmen Underground Neutrino Observatory, or JUNO—plans to hunt the elusive neutrino with better sensitivity than ever before. Expected to be operational in 2024, this detector will not only be bigger, but also more sensitive to slight variations in neutrinos’ energies than any of its predecessors.

LuSEE-Night will demonstrate whether an experiment to search for ancient radio signals can survive the moon’s unforgiving environment.

In a race against the clock, CERN engineers and technicians pulled together to find and fix a leak inside the Large Hadron Collider.

From Big Think: A recent series of precise measurements of the Moon confirms that there are two types of mass which are the same. In Einstein’s most advanced theory, there are three “kinds” of mass that are thought to be one and the same but there is no fundamental reason why. Don Lincolns explains why.

Indirectly testing this theory, motivated by the mysterious mass of the Higgs boson, could be within reach for experiments at the Large Hadron Collider.

From Unicamp (upon opening the link, right click to translate to English): Last week, directors and scientists from Unicamp (the University of Campinas) and other research institutions visited Fermilab as part of the critical assessment by DOE on the progress of the international collaboration in building the large underground neutrino detector at LBNF. The University is responsible for the development and subsequent production of two sets of central equipment that will make up the laboratory to be installed in South Dakota 1,500 meters underground. One of the sets will be used to detect photons and the other to purify liquid argon.

From U Chicago News: On Sept. 30, the University of Chicago will be hosting its second annual South Side Science Festival inviting visitors to explore ways science impacts our daily lives. This year’s festival includes an up-close look at live butterflies, quantum science games, CPR practice, live demonstrations, local food vendors, music and a Science Slam. The South Side Science Festival will be held from 11 a.m. to 6 p.m. on Sept. 30 on the University of Chicago campus at 929 E 57th St.

To understand why scientists are excited about detecting a new background, just look to the history of studies of the CMB.
