Madden combed through this sparse record, confirming the oldest-known dice and establishing an unbroken, previously hidden lineage of chance-based games dating back at least 12,000 years, 6,000 before any counterpart in the Old World.

To characterize CREs and TFs for neocortical ExNs, we used Arpp21-Gfp or Fezf2-Gfp transgenic mice and enriched GFP-expressing neocortical upper layer (L2-4) intratelencephalic (IT) neurons or deep layer (L5-6) predominantly extratelencephalic (ET) neurons, respectively, from neonatal mice (postnatal day (PD) 0), an age at which neocortical ExN identity and connectivity are established.

Social foraging strategies illustrate the balance between competition and cooperation, where individuals either produce resources or exploit the efforts of others, navigating ecological and social constraints.

Attention is the brain's filtering mechanism; what passes through that filter is what gets encoded. What gets encoded becomes memory. And memory is the raw material of identity. So in the architecture of your identity, attention is the doorway.

I'm always looking for books that challenge the status quo, and when I learned about Roland Ennos' new book The Powerful Primate: How Controlling Energy Enabled Us to Build Civilization, I couldn't wait to get my eyes on it, and I'm thrilled I did. In this landmark book, Ennos offers "a compelling argument that flips the traditional view of humanity on its head."

The movie opens with a brief prologue. A family is driving at night. They hit something on the road, which turns out to be a dog, and the dog dies. The daughter in the back seat is visibly upset. The mother consoles her by saying, "It was just an accident-Dad didn't do it on purpose." Then the title appears, and the main story begins.

The fighting hypothesis proposes that there is a so-called frequency-dependent maintenance of left-handedness. The main idea is that over the tens of thousands of years of human evolution, left-handers did have an advantage in fights due to a surprise effect. This gives them an evolutionary survival benefit since they win more fights.

Researchers studying brain-imaging data from people aged between 8 and 100 found that sex differences in the brain's connections are minimal in early life, but then increase drastically at puberty; some of these differences continue to grow throughout adult life. The study was published as a preprint on bioRxiv, and has not yet been peer reviewed. The work could help us to understand why men and women have different likelihoods of developing some mental-health disorders - and perhaps give insight into treating them, say the researchers.

Some of the most meaningful forms of growth an individual can experience happen beneath their conscious awareness. Typically, it registers first as discomfort, ambiguity, or even a sense of regression. When growth is happening at a person's core level, they're likely to underestimate it or misinterpret it entirely. As a psychologist, I often see individuals who assume they're "stuck" precisely when some of the most important internal shifts are underway. This is because the mind rarely announces these changes with clarity.

Somewhere between six and seven million years ago, our ancestors began walking upright, and the advantages were considerable: Freed from locomotion, upper limbs could grasp, manipulate, eventually craft, and the opposable thumb became the hinge on which human civilization would turn. We are, above all else, tool users-fire, the wheel, writing, the printing press, the transistor-each tool reshaping not only what we could do but who we became.

For Plato, psyche meant something like what we'd now call mind -understood as a complex system requiring governance. The psyche had distinct parts: a reasoning part that deliberates, a spirited part that feels emotion and courage, and an appetitive part that desires. Each part has its own function and its own form of excellence. And crucially, these parts need to be governed-integrated under what Plato called constitutional self-rule.

Recently, two unexpected examples by a wild wolf and a domesticated cow named Veronika attracted global attention and once again opened the door for experts and others to weigh in on the question, "Are these really examples of tooling?" Many people are eager to know more about the nitty-gritty details of tooling, so I am thrilled that Dr. Benjamin Beck, an expert in this area, could answer a few questions about this fascinating behavior.

Studies show that people with high fluid intelligence can process multiple "what if" scenarios concurrently, helping them see ahead, identify concealed dangers, and plan their actions. This mode of thinking requires a lot of working memory because the brain isn't looping idly; it's stress-testing every single possibility that comes to mind. This might be why these people seem to be frequently lost in their thoughts, even when they're alone.

The study's authors researched 96 peer-reviewed studies documenting SSB to compile one of the most comprehensive datasets for primates to date. The study found that SSB are a "persistent and integral component of primate social [practices]." In fact, the prevalence of SSB across a variety of closely related primate species - and over several lines of descendants - "indicates a deep evolutionary root or multiple independent evolutionary origins," the study's authors wrote.

The mirror spider can rapidly shift a patchwork of minuscule reflective plates underneath its abdomen's outer surface, altering the pattern of mirrorlike flashes. This uncommon display comes from common building blocks: Similar tilelike arrangements of plates and soft joints appear throughout the tree of life, from turtle shells to tropical fruit peels. Researchers have now compiled 100 examples of this pattern across animals, plants, microbes and viruses, which they describe in PNAS Nexus.

I am a worrier, and have been for most of my life. At some point, someone dear and smart teased me that I worry about the wrong things. The things that hit me, she noted, were never the things I worried about. For a while that left me feeling like an incompetent worrier-until my research caught up. I realized that the things I worry about often don't end up hurting me precisely because worrying helps me diffuse them ahead of time.

They're displaying a fascinating set of personality traits that go much deeper than having their finances sorted. 1) They have exceptional impulse control Think about what it takes to always have exact change ready. You need to resist the urge to spend those coins on vending machines or leave them as tips. You have to plan ahead, knowing what you'll buy and preparing accordingly.
