Ancient hobbit-like humans may have survived on meat left behind by Komodo dragons
Ancient hobbit-like humans may have survived on meat left behind by Komodo dragons
Arguably one of the most curious ancient human relatives is Homo floresiensis, a 3-foot-tall species that lived on the Indonesian island of Flores and has been nicknamed "hobbit" for its diminutive stature. Even though they had small brains, scientists had thought they were surpr
Scientists observe water's behavior in a single molecular layer
Scientists observe water's behavior in a single molecular layer
New research has revealed that water behaves differently when confined to spaces just one molecule thick. For the first time, scientists have directly measured the vibrational signatures of truly two-dimensional water. In a study published in Nature Communications, researchers us
Atomic-level engineering of Cu nanoclusters improves conversion of CO₂ to fuel
Atomic-level engineering of Cu nanoclusters improves conversion of CO₂ to fuel
Researchers at Tohoku University have discovered a promising strategy that converts harmful carbon dioxide into valuable fuels and chemicals by precisely altering nanoclusters made of copper.

Larger brain, smaller face: Human evolution took a different course than previously though
A new study, published July 6, 2026, in the journal Nature Communications, suggests that two of the best-known trends in human evolution—brain growth and the reduction in the size of the face and jaw—may be far less attributable to directed natural selection than scientists have

Discrepancies in AI lunar crater catalogs discovered
A new Southwest Research Institute-led study compared eight AI-generated lunar crater catalogs, discovering that many of their published performance metrics drop sharply when the databases are evaluated using the same scientific standards humans are held to. Crater catalogs provi
Childhood trauma may erode adult relationships through daily communication struggles
Traumatic events from your childhood could have a lingering impact on your adult relationships, according to new research from the University of Georgia.

Four new groups of indigenous cacao varieties discovered in Peru
A new genetic analysis of hundreds of cacao trees representing traditional Amazonian varieties grown on farms across Peru has revealed four previously unidentified, genetically distinct groups. Lambert Motilal, with colleagues from the Cocoa Research Center, The University of the
Unexpected discovery yields new graphene oxide production method
Researchers in the Texas A&M University J. Mike Walker '66 Department of Mechanical Engineering have developed a new method for producing graphene oxide, a high-value carbon nanomaterial used in batteries, electronics and advanced manufacturing.
Survival comes at a price: Frog study links salt adaptation to increased risk of disease
Survival comes at a price: Frog study links salt adaptation to increased risk of disease
Over generations, a small North American frog has learned how to survive in a world that's getting increasingly saltier. But new research from the University of Missouri suggests that adaptation comes with an unexpected trade-off.

Engineers discover 'unexpected motion' in drug-delivery robots
One day, tiny swimming robots may travel through the human body to deliver drugs. The medication would target only areas of need—chemotherapy drugs for a tumor, for example—avoiding healthy tissue and minimizing side effects. A research team led by Ebru Demir, an assistant profes
