Scientists define new type of memory loss in older adults
Researchers have established new criteria for a memory-loss syndrome in older adults that specifically impacts the brain’s limbic system. It can often be mistaken for Alzheimer’s disease.

Cuttlefish can form false memories, too
During an event, details like what you saw, smelled, and felt aren’t stored as a single memory. Rather, they are encoded and stored in your brain separately. To retrieve that memory, those pieces must get put back together. When that…
Physicists develop new theory describing the energy landscape formed when quantum particles gather together
An international team of physicists has proven new theorems in quantum mechanics that describe the ‘energy landscapes’ of collections of quantum particles. Their work addresses decades-old questions, opening up new routes to make computer simulation of materials much more accurate.…
New technique pinpoints nanoscale ‘hot spots’ in electronics to improve their longevity
Researchers engineered a new technique to identify at the nanoscale level what components are overheating in electronics and causing their performance to fail.
Aussie innovation spearheads cheaper seafloor test for offshore wind farms
Australian engineers have unveiled a clever new device — based on a modified speargun — as a cheap and efficient way to test seabed soil when designing offshore wind farms.
A hydrogel implant to treat endometriosis
Researchers have developed a hydrogel implant that can help prevent endometriosis, a condition that affects a great many women. This innovation also acts as a contraceptive.
Powerful new particle accelerator a step closer with muon-marshalling technology
New experimental results show particles called muons can be corralled into beams suitable for high-energy collisions, paving the way for new physics.
Designing safer opioids
Opioid medications offer people relief from debilitating pain, but these drugs come with dangers: the risk for addiction, miserable withdrawal symptoms and the potential for fatal overdose. Researchers have now identified a strategy to design safer opioids. They showed that…
Although tiny, peatland microorganisms have a big impact on climate
Polyphenols are generally toxic to microorganisms. In peatlands, scientists thought microorganisms avoided this toxicity by degrading polyphenols using an oxygen-dependent enzyme, and thus that low-oxygen conditions inhibit microbes’ carbon cycling. However, a new study found that Arctic peatland microorganisms used…
Sea ice’s cooling power is waning faster than its area of extent
As sea ice disappears and grows less reflective, the Arctic has lost around a quarter of its cooling power since 1980, and the world has lost up to 15%, according to new research.
Ancient viruses fuel modern-day cancers
The human genome is filled with flecks of DNA left behind by viruses that infected primate ancestors tens of millions of years ago. Scientists used to think they were harmless, but new research shows that, when reawakened, they help cancer…
The most endangered fish are the least studied
The most threatened reef fishes are also the most overlooked by scientists and the general public. Scientists measured the level of human interest in 2,408 species of marine reef fish and found that the attention of the scientific community is…
Reef pest feasts on ‘sea sawdust’
Researchers have uncovered an under the sea phenomenon where coral-destroying crown-of-thorns starfish larvae have been feasting on blue-green algae bacteria known as ‘sea sawdust’.
Diatom surprise could rewrite the global carbon cycle
When it comes to diatoms that live in the ocean, new research suggests that photosynthesis is not the only strategy for accumulating carbon. Instead, these single-celled plankton are also building biomass by feeding directly on organic carbon in wide swaths…
Discovery of a hybrid lineage offers clues to how trees adapt to climate change
The discovery of a hybrid population of poplar trees in western Wyoming has provided insight into how natural hybridization informs the evolution of many plant species, according to researchers. They also said their discovery suggests that genetic exchange between species…
New study reveals a surprising fact about aging and touch sensitivity
Our sense of touch is generally thought to decline with age, just like the other senses. However, a study has now shown for the first time that age-related decline in sensitivity only happens in hairless skin like the tip of…
Mediterranean diet linked to reduced risk of cognitive decline in elderly women
A recent study published in Nutritional Neuroscience has found that greater adherence to the Mediterranean diet is linked to a reduced risk of cognitive decline among elderly individuals. Conducted over a three-year period, the research highlights that this association is…
Scientists observe lasting cognitive deficits in long COVID patients
A recent study by neurology researchers at the Hospital ClÃnic de Barcelona has shed light on the cognitive impairments experienced by individuals suffering from post-acute COVID-19 syndrome. Their findings reveal significant cognitive deficits, particularly in attention, executive function, and verbal…
People who believe conspiracy theories tend to report greater childhood adversity
Conspiracy theories are often seen as the domain of the paranoid and mistrustful, but new research suggests a deeper, more evolutionary reason for why some people are more inclined to believe in them. A recent study published in the journal…
Nature exposure might help restore cognitive capacities of children and adolescents
A meta-analytic study examining the associations between nature exposure and the cognitive performance of children and adolescents found no significant link between the two. However, a meta-analysis of 34 nature exposure experiments found that, overall, they did produce small improvements…
