When huge scientific discoveries are made, you may hear that they are "statistically significant" or pass a threshold called "5 sigma" - but those calculations can be manipulated to make claims seem grander than they are...

New research shows that HIV drugs called NRTIs may significantly reduce the risk of developing Alzheimer's disease. Analyzing two large health databases, scientists found that patients on NRTIs had a 6% to 13% annual dec...

New research reveals that mammals with larger brains and more robust immune systems tend to live longer lives. By studying 46 species, scientists found a clear link between maximum lifespan and the expansion of immune-re...

The brain's meningeal lymphatic system plays a key role in clearing waste and transporting immune cells, but until now, how it develops was unclear. Using zebrafish and advanced imaging, researchers revealed that neural ...

In collisions of argon and scandium atomic nuclei, scientists from the international NA61/SHINE experiment have observed a clear anomaly indicative of a violation of one of the most important symmetries of the quark worl...

A newly identified mutation helps super-sleepers get by on just four to six hours of shut-eye per night, while the rest of us need around eight hours. Researchers described the SIK3-N783Y mutation in a new study after te...

A report into April's deadly flooding has found that climate change made the central Mississippi River valley's extreme weather event more likely and more intense.

A coin stash worth more than $340,000 could have been hidden in the hills of the Czech Republic during one of the 20th century's greatest upheavals. Historians are attempting to unravel the mystery.

In a paper published in Physical Review C, the ALICE collaboration reports measurements that quantify the transmutation of lead into gold in CERN's Large Hadron Collider (LHC).

Researchers think the vehicle was used as a staff car by naval officers during World War II.

A new report reveals that parents' genes influence their children's educational and mental health outcomes, even when not directly inherited. This phenomenon, called "genetic nurture," shows that parents' genetic tendenc...

The Weed Care study in Switzerland is investigating how legal access to cannabis affects users' consumption and mental health. In the first randomized trial of its kind, participants buying cannabis legally showed a slig...

Very little is known about Powelliphanta augusta, an elusive snail species threatened with extinction. The new footage is the first time their bizarre egg laying behavior has been captured on camera.

Molding the flow of light--whether confined to localized regions or propagating in free space--remains crucial for modern integrated photonics. The advancement of the multi-channel, programmable optical waveguide and cou...

Eggs are less likely to crack when dropped on their side than when dropped vertically, finds research published in Communications Physics. Controlled trials simulating the "egg drop challenge," a common classroom science...

New research suggests that while general curiosity tends to decline with age, specific curiosity, or "state curiosity", actually increases later in life, potentially protecting against cognitive decline. Older adults sho...

Asian needle ants found in the southeastern states of the U.S. have been spreading north and west for years, but experts now consider them to be a medically important pest and urge caution.

A revolutionary microscopy method called LICONN enables scientists to reconstruct brain tissue and map synaptic connections using standard light microscopes. By embedding brain tissue in hydrogel, expanding it, and imagi...

Simulations suggest that an extraordinary jump in temperatures seen in 2023 and 2024 could simply be natural variability, rather than a new phase of climate change as some researchers have suggested

Healthy hearts show complex, adaptive rhythms that reflect resilience to internal and external changes. Researchers applied a novel method to analyze heart rate complexity using wearable pulse oximeters and found that gr...

People are more likely to choose to empathize with groups rather than individuals, even though they find empathizing equally difficult in both scenarios. Using a card-based empathy selection task, participants opted to e...

The rules about magnetic order may need to be rewritten. Researchers have discovered that chromium selenide (Cr2Se3)--traditionally non-magnetic in bulk form--transforms into a magnetic material when reduced to atomicall...
