The LHC just ruled out another hiding place for quantum black holes
Physicists searching through Large Hadron Collider data found no evidence that the machine has been producing microscopic quantum black holes, but the result sharply narrows where such exotic physics could still be hiding. These hypothetical black holes could
One of America’s largest reservoirs just hit a record low
Lake Powell has fallen to its lowest level on record after an exceptionally dry and warm winter left the Colorado River Basin with little mountain snow to melt. Lake Mead also reached record lows, raising concerns for a river system that supplies water and pow
This new drug could break cancer’s resistance to treatment
A new experimental drug called CS18 may help break through cancer drug resistance by disabling several of the defenses tumors use to survive treatment. It strengthened existing therapies, restored drug sensitivity in resistant lung cancer cells, and slowed tum
