Phys.org / A child's environment may shape how their brain solves problems
For decades, researchers have documented an achievement gap between children from higher- and lower-income families. On average, children with more resources perform better in school and on cognitive tests.
Phys.org / Cut marks on 1.6 million-year-old bones reveal early humans moved prized meat
There is an old adage that goes, "you are what you eat," meaning that the food you consume helps build your body and fuel your mind. The same is true now as it ever was. When it comes to early humans, studying what they ate ...
Phys.org / NASA's Psyche spacecraft buzzing Mars on its way to a rare metal asteroid
A NASA spacecraft chasing a rare metal asteroid swings past Mars this week for a gravity boost, snapping thousands of pictures as practice for the main encounter in 2029.
Phys.org / Bright blazar reveals 433-day optical quasi-periodic oscillation across nine years
By analyzing the data from the Whole Earth Blazar Telescope (WEBT), an international team of astronomers has discovered optical quasi-periodic oscillation (QPO) in a bright quasar known as 3C 454.3. It is so far one of the ...
Phys.org / More Star Wars-like worlds emerge as 27 planet candidates with two suns discovered
There's so little we know about circumbinary planets—planets that orbit two stars instead of one—that they can feel like the stuff of fantasy. And for good reason: to date, we've only confirmed the existence of 18 circumbinary ...
Phys.org / Meet the whistling mice that use inflatable air sacs to sing
Mice do more than just squeak when they want to make a noise. They can also sing. And the way they do it is different from most mammals that produce sounds by vibrating their vocal cords. When Alston's singing mouse (Scotinomys ...
Medical Xpress / New study challenges the idea that testosterone drives risk-taking behavior
Men are more likely to take risks in tricky situations than women, but whether there is an inherent biological reason behind it is a question researchers have been asking for quite some time. A popular theory suggests that ...
Phys.org / Buried in dark waters, viruses reshape one of Earth's largest carbon systems
Viruses play a far more active role in Earth's carbon cycle than previously understood, according to new research that reveals how they infect and control microbes responsible for carbon production in some of the planet's ...
Phys.org / Scurvy's skeletal fingerprint found in California's Late Holocene archaeological sites
A recent study published in the International Journal of Osteoarchaeology documented skeletal changes linked to scurvy in Late Holocene archaeological sites in California (500 BCE–1834 CE). The change observed shows the cascading ...
Phys.org / Satellite launch pollution is rapidly accumulating in the upper atmosphere
The potent pollution from so-called megaconstellation satellite systems launched en masse into space since 2019 will account for nearly half (42%) of the total climate impact of space sector pollution by the end of the decade, ...
Medical Xpress / Cancer risk awareness and concrete plans boosted gastric screening during COVID-19
A study conducted by researchers at University of Tsukuba revealed that individuals with higher cancer-related health literacy, perceived susceptibility to gastric cancer, and encouragement from family members or health care ...
Medical Xpress / Genes give neurons a 'GPS' to form the brain's neural circuits, scientists show
How complex neural circuits are genetically designed and wired is a fundamental question in neuroscience. Scientists have shown for the first time that genes encode a "wiring map" that guides neurons to connect with the correct ...
