When the US Department of Justice approved Paramount Skydance's proposed acquisition of Warner Bros. Discovery on Friday, a DOJ press release said "a rigorous eight-month investigation led by the [Antitrust] Division’s career staff" showed that the $111 billion deal would not harm competition or American consumers.
But according to The Wall Street Journal, the DOJ career lawyers who led that investigation "were leaning toward recommending a lawsuit challenging it on the grounds that the combination of the two movie studios would be anticompetitive and violate antitrust law." DOJ senior leaders closed the investigation "before career staffers who were concerned about the acquisition had an opportunity to object, according to people familiar with the matter," the WSJ reported.
Commenting on the report that the decision to allow the deal surprised staff investigators, Sen. Elizabeth Warren (D-Mass.) wrote that "the American people need to know if this merger was approved as a political favor. This reeks of corruption."

This piece summarises published research on ageing and emotional well-being. We are not psychologists or clinicians, and nothing here is psychological advice. If you’re struggling with mood, isolation, or a life-stage transition of the kind discussed, a licensed psychologist or your GP is the right place to start.
“When we recognize that we don’t have all the time in the world, we see our priorities most clearly. We take less notice of trivial matters.” That is Laura Carstensen, a Stanford psychologist, describing the shift her research traces in how people spend their attention as they age.
And it is probably not the story most of us expect ageing to tell.
The familiar picture of growing older is one of contraction. The social circle thins. Ambition cools. The appetite for new people, new places and new experiences fades, and what remains looks like a managed decline.
Read that way, an older person with fewer friends and narrower routines is a person who has lost something and is making do with the remainder.
That reading treats the narrowing almost as damage. Carstensen’s work, developed through her socioemotional selectivity theory, points somewhere stranger. The narrowing is real, but it is largely chosen rather than imposed.
The shift she documents is selective rather than passive. Older adults do not simply lose contacts; they prune the peripheral ones and hold onto the people who matter most. They put less effort into meeting new people and more into the relationships they already have. When time feels limited, the theory holds, people are motivated to pursue emotional satisfaction over information.
That motivation shows up as a particular set of preferences. Carstensen describes older adults as “more likely to invest in sure things, deepen existing relationships, and savor life.” The hedge in her own phrasing matters. This is a tendency the research finds, not a rule every person follows.
One detail makes the pattern hard to dismiss as mere mellowing. In a memory study, Carstensen found that older adults remembered nearly twice as many positive images as negative or neutral ones — a skew toward the good that younger adults did not show. Attention itself appears to reorganise around what feels emotionally worth keeping.
The central claim is that age is not really the cause. One key tenet of the theory, in Carstensen’s words, is that “perceived time horizons, not chronological age, account for age differences in goals and preferences.” What changes behaviour is the sense of how much time remains, and that sense usually shortens with age, though not always for the same reasons.
The contrast with youth is the cleanest test. When time horizons are long, Carstensen says, “people are constantly preparing, trying to soak up all the information they can.” This makes sense when you are building toward an open future, and tends to lose its appeal once the future feels finite.
Carstensen and colleagues found that shortening or expanding a person’s sense of remaining time changed their goal preferences regardless of how old they were. A similar effect surfaced again under unusual conditions: an analysis published in Psychological Science found that the age advantage in emotional well-being held up during the early COVID-19 pandemic, with older adults reporting better emotional experience than younger ones even under a shared acute threat.
If ageing were simply loss, emotional life should worsen with it. Instead, research suggests the opposite.
Her explanation for the paradox is plain. She describes the sequence this way: “we invest in more emotionally important parts of life and life gets better.” It tends to get better, in her reading, because the investment has shifted to the things that reliably pay off in contentment.
Seen through Carstensen’s lens, the older person with a smaller circle and quieter ambitions is not a diminished version of their younger self. They are perhaps simply someone acting on a clearer sense of what their time is for. The same behaviour that looks like withdrawal from the outside can be, from the inside, a deliberate reallocation toward what already matters.
The practical reach of the idea extends well beyond ageing. Because perceived time, not the calendar, sets the priorities, anyone whose horizon suddenly shortens — through illness, upheaval, or simply paying attention to the clock — can find the same reordering arriving early. Later life is simply where it shows up most reliably.

US scientists have shed light on the physics behind diamond’s superconductivity, which could help engineers develop more powerful quantum devices, including multifunction quantum chips.
The joint research team consisted of experts from the US Department of Energy’s (DOE) Argonne National Laboratory (ANL), Pennsylvania State University, and the University of Chicago Pritzker School of Molecular Engineering. It discovered new insights into how electricity can flow through a diamond without resistance under the right conditions.
The findings could lead to multifunctional quantum chips capable of combining several quantum technologies within a single material. “This offers a new way of thinking by integrating superconducting and semiconductor behavior to create opportunities for multifunction quantum devices,” David Awschalom, PhD, from UChicago PME, said.
According to Awschalom, who is the Liew Family Professor of Quantum Science and Engineering and Physics at UChicago PME and the director of the Chicago Quantum Exchange, the breakthrough could make quantum technologies more efficient and better integrated with classical technologies.
Diamond is valued in advanced technology because of its exceptional hardness, optical properties, and thermal conductivity (Tc). It features the highest thermal conductivity and mineral hardness of any material known. It can also become superconducting when doped with boron, an element that alters its electrical conductivity.
More than two decades ago, scientists discovered that diamond can also become superconducting when doped with atoms of boron, an element that can alter its electrical behavior. Until now, however, the mechanisms behind the phenomenon remained largely unclear.
To analyze the phenomenon, the researchers synthesized high-quality diamond thin films, which contained carefully distributed boron atoms. They were stunned to find that despite appearing structurally uniform, the films had a hidden mosaic of microscopic superconducting regions.
The research team called these regions “puddles.” It was further discovered that they eventually connect with one another, therefore allowing electrical current to travel through the material without resistance.
“This serendipitous discovery caught us totally by surprise because these are structurally homogeneous, crystalline films,” Nitin Samarth, PhD, the Verne M. Willaman Professor of Physics and Materials Science and Engineering at Penn State, and co-corresponding author of the paper, said. “So, the question was: Where is this granularity coming from?”
According to the researchers, these superconducting regions are not fixed. Their shape and behavior can be modified by changing magnetic fields, temperature, and electrical currents. The researchers believe they can learn to connect them more efficiently by identifying how electrons move between them.
This could boost the performance of future quantum devices and allow them to operate at higher temperatures. Meanwhile, several parameters can be adjusted independently to tailor the material’s properties, including boron concentration, crystal orientation, mechanical strain, and dimensionality.
“We now have a reliable roadmap for engineering diamond superconductors by independently adjusting the material’s core properties,” Samarth said in a press statement. “There are a lot of exciting possibilities here, for both quantum and classical technology.”
Awschalom noted that the discovery could lead to the creation of multifunctional quantum-on-chip devices. “Imagine a future technology that combines light, spin, superconductivity, and magnetism, all in a single material that one could also integrate with today’s microelectronics,” he concluded.
The study has been published in the journal Proceedings of the National Academy of Sciences (PNAS).
