How does a single cell build a brain with billions of precisely organized neurons。 Researchers suggest that brain cells use their lineage—their cellular family tree—as a kind of positional map。 Cells that come from the same ancestor stay near one another, helping the brain organize itself without relying solely on chemical signals
The race to build data centers in space is gaining momentum as AI drives unprecedented demand for computing power。 Orbital facilities could tap into abundant solar energy and avoid many of the environmental challenges faced on Earth。 Yet space remains a harsh and expensive place to operate, with major hurdles including cooling, maintenance, radiati
Factors like the short interval between the two powerful quakes and different types of soil led to some structures collapsing while others stayed standing
As newborn neurons make their way through the developing brain, they must squeeze through incredibly tight spaces to reach their final destinations。 Researchers discovered that this physical journey routinely causes some of the most severe forms of DNA damage—double-strand breaks—yet the young brain has evolved an impressive ability to repair the d
Director Travis Knight is also the creative mind behind 2016's Oscar-nominated Kubo and the Two Strings
The Chinese supercomputer LineShine was ranked as the fastest in the world, despite not using any GPUs

Scientists have discovered a “ballista spider” that builds a spring-powered silk trap designed specifically to catch aggressive green tree ants。 The ant unknowingly triggers the mechanism itself, launching into the spider’s web in one of nature’s most extraordinary hunting strategies
Humans evolved to pay close attention to danger, but today that instinct is being overwhelmed by an endless supply of bad news from around the world。 Researchers say the answer isn’t to stop following current events—it’s to build healthier habits around how, when, and where we get our news
A newly identified molecule called OLE helped restore the brain’s immune cells to a more protective state in Alzheimer’s models。 The treatment reduced toxic plaque buildup and improved memory, raising hopes for a new therapeutic approach
Creatine is best known as a muscle-building supplement, but scientists are now investigating whether it could also help treat depression by boosting the brain's energy supply。 A new review examined five randomized clinical trials involving 238 participants and found mixed results。 Two studies, both involving women with major depressive disorder, re
Scientists have found that staple-shaped particles can tangle together to create a material that is both strong and flexible。 Unlike conventional materials, these particles can be locked into a sturdy structure or rapidly unraveled using vibrations。 The unusual behavior could open the door to recyclable buildings, reconfigurable structures, and eve
Zuckerberg’s plans for Arena, a prediction markets app that Meta is building, also include appealing to 18- to 34-year-old users
(财联社) 韩国启动史上最大规模产业投资计划 6月29日,韩国政府宣布迄今规模最大的半导体与人工智能产业投资计划,总投资规模超过5760亿美元,将半导体、物理AI与AI数据中心定位为韩国产业升级的“三角支柱”
Astronomers studying the rare supernova SN 2021yfj discovered material from one of the deepest layers of a dying star, providing a rare look at its hidden interior。 The finding confirms key theories about how massive stars forge the elements that help build planets, worlds, and life
Scientists at UCLA have linked long-term exposure to the pesticide chlorpyrifos with a sharply increased risk of Parkinson’s disease。 People exposed to the chemical near their homes were more than twice as likely to develop the condition。 Laboratory studies showed that chlorpyrifos damages dopamine neurons and interferes with the brain’s ability to
