AMD just reported its Q2 2025 earnings, and it’s attributing a new quarterly revenue record of $7.7 billion to one particular thing: “record server and PC processor sales.” And while AMD doesn’t mention its flagging competitor Intel, it seems many are turning to Team Red: AMD just crossed 40 percent market share for the first time on the Steam Hardware Survey of PC gamers, and it may have 40 percent server market share soon too.
The periodic table is one of the triumphs of science. Even before certain elements had been discovered, this chart could successfully predict their masses, densities, how they would link up with other elements, and a host of other properties.
But at the bottom of the periodic table, where massive atoms are practically bursting at the seams with protons, its predictive power might start to break down. Experiments to study the chemistry of the heaviest elements — especially the superheavy elements, which have more than 103 protons — have long been a challenge. Despite using specialized facilities, researchers have been unable to definitively identify the molecular species they produce in experiments. This uncertainty has hindered progress in the field, since scientists have had to rely on educated guesses rather than precise knowledge of the chemistry being observed.
Now, researchers have used the 88-Inch Cyclotron at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) to develop a new technique to make and directly detect molecules containing heavy and superheavy elements. In a study published today in the journal Nature, a team of researchers from Berkeley Lab, UC Berkeley, and The University of Alabama used the method to create molecules containing nobelium, element 102. It is the first time scientists have directly measured a molecule containing an element greater than 99.
A group of Chinese scientists has created powerful new tools that allow them to edit large chunks of DNA with incredible accuracy—and without leaving any trace. Using a mix of advanced protein design, AI, and clever genetic tweaks, they’ve overcome major limitations in older gene editing methods. These tools can flip, remove, or insert massive pieces of genetic code in both plants and animals. To prove it works, they engineered rice that’s resistant to herbicides by flipping a huge section of its DNA—something that was nearly impossible before.
The development of wearable electronics and the current era of big data requires the sustainable power supply of numerous distributed sensors. In this paper, we designed and experimentally studied an energy harvester based on ferrofluid sloshing. The harvester contains a horizontally positioned cylindrical vial, half-filled with a ferrofluid exposed to a magnetic field. The vial is excited by a laboratory shaker and the induced voltage in a nearby coil is measured under increasing and decreasing shaking rates. Five ferrofluid samples are involved in the study, yielding the dependence of the electromotive force on the ferrofluid magnetization of saturation. The energy harvesting by ferrofluid sloshing is investigated in various magnetic field configurations. It is found that the most effective magnetic field configuration for the energy harvesting is characterized by the field intensity perpendicular to the axis of the vial motion and gravity. The harvested electric power linearly increases with the ferrofluid magnetization of saturation. The electromotive force generated by each ferrofluid is found identical for measurements in acceleration and deceleration mode. A significant reduction in the induced voltage is observed in a stronger magnetic field. The magneto-viscous effect and partial immobilization of the ferrofluid in the stronger magnetic field is considered. The magneto-viscous effect is documented by a supplementing experiment. The results extend knowledge on energy harvesting by ferrofluid sloshing and may pave the way to applications of ferrofluid energy harvesters for mechanical excitations with changing directions in regard to the magnetic field induction.
