Medical Xpress / Early deafness may reshape the brain to devote more resources to peripheral vision
People with intact hearing can use sound as an alert system for events outside their direct line of sight. This seemingly puts those who have lost their hearing at a disadvantage. However, according to a new study published ...
Phys.org / Southern Ocean may flip from carbon sink to carbon source under mitigation scenarios
Plans to limit the global temperature rise to 1.5°C above preindustrial levels depend on reaching net-zero emissions and, in many cases, actively removing carbon dioxide (CO2) from the air. While this helps limit extreme ...
Phys.org / Continuous video of black hole radio observations challenges shock wave theory
For years, scientists have relied primarily on radio imaging from techniques like very long baseline interferometry (VLBI) to study jets from the active galactic nuclei of supermassive black holes. This allows for the detection ...
Phys.org / The 'costly son' hypothesis: Why bigger sons may make births riskier across species
A new comparative review, published in The Anatomical Record, examines factors that may lead to birth complications among humans and other mammals. The study suggests that fetal sex may play an important role in risky births ...
Phys.org / Plants' response to rising CO₂ could put the brakes on dryland expansion
Drylands are defined as regions where rainfall is low relative to the atmosphere's ability to draw water from soil and plants. Expanding boundaries of these regions are frequent concerns in climate change considerations. ...
Medical Xpress / Understudied gut fungus may help repair radiation-damaged DNA and limit intestinal injury
The gut microbiome has been a popular topic for a while now, but the focus is usually on good bacteria. A new study, published in the journal Proceedings of the National Academy of Sciences, suggests that we may want to pay ...
Phys.org / Six unusual structures identified at Earth's core-mantle boundary with the help of deep learning
Since scientists can't drill 2,900 km (1,800 miles) to the boundary between Earth's core and deep mantle, they must use information relayed by seismic waves recorded during earthquakes to study this region. In a new study ...
Phys.org / AI helps reveal the immersive sensory experiences of ancient Etruscan tombs
The Etruscan painted tombs in Tarquinia, Italy, date to the first millennium BCE and are known for their vivid scenes of music, feasting, processions and the afterlife. While these tombs have been extensively studied, archaeologists ...
Phys.org / Weak sea-surface temperature gradients may fuel stronger tropical cyclones
The fact that the ocean gets colder as you go deeper is fairly intuitive, but a similar gradient exists along the surface of the ocean, even at scales of 1 kilometer to tens of kilometers. A new study, published in the Proceedings ...
Phys.org / Geomagnetic superstorm shook GPS accuracy across the US—its timing may have averted agricultural losses
On Nov. 11, 2025, Earth experienced a severe geomagnetic storm triggered by solar flares and coronal mass ejections from an active sunspot region. While this kind of storm brings beautiful auroras admired in many areas around ...
Phys.org / An anomalous return of the Odden ice tongue suggests unusual Arctic conditions
Data from many sources, including NASA, have shown a significant decrease in Arctic sea ice since 1979. However, the processes driving the melting and freezing of sea ice are complex, and fluctuations occur throughout the ...
Phys.org / Egypt's deserts were once home to a diverse shark community
During the Late Cretaceous period, parts of Egypt were covered in water. A new study, published in the journal Cretaceous Research, describes new evidence that this tropical sea was home to a diverse community of sharks. ...
Phys.org / Cowpea plants create underground defense system for the next generation after insect attacks
Plants might seem helpless when it comes to insect attacks, but they are known to employ various techniques to deter pests. One of these techniques involves sending out signals to recruit parasitoid wasps, and a new study, ...
Phys.org / LHC collisions reveal oxygen and neon's shifting nuclear geometry
Many people are aware that the Large Hadron Collider (LHC) at CERN smashes tiny subatomic particles together at nearly the speed of light to test foundational laws of physics and discover new fundamental particles, but some ...
Phys.org / Stone tools suggest Neanderthals once inhabited Arabian deserts
Neanderthals are largely associated with colder climates across Eurasia. But researchers know that both Homo sapiens and Neanderthals moved through nearby Southwest Asia between about 100,000 and 50,000 years ago, and Arabia ...
