Mice’s learning skills help researchers pinpointing brain areas where acquired knowledge is stored
Is it a Rembrandt or a Vermeer? For lay people, it is often challenging to distinguish paintings by these two old masters. For the trained eye of an expert, on the other hand, it is not difficult at all. Scientists have now demonstrated that mice can also become experts in sorting images into categories. The study shows that part of the category knowledge is already present in early visual areas, highlighting how widespread such semantic memories are stored throughout the brain. mehr ...

Pioneering EEG test could dramatically increase early diagnosis of Alzheimer’s
Researchers have developed a two-minute passive-test, 'Fastball EEG', that measures people's brain waves in response to a series of images and could help expand early dementia diagnosis. mehr ...

Modern activities follow the contours of ancient Teotihuacan
A lidar mapping study shows ancient residents of Teotihuacan moved astonishing quantities of soil and bedrock for construction and reshaped the landscape in a way that continues to influence the contours of modern activities in this part of Mexico. The paper also shows how Teotihuacan's engineers re-routed two rivers to align with points of astronomical significance, identified hundreds of previously unknown architectural features, and documented over 200 archaeological features that have been destroyed by mining and urbanization since the 1960s. mehr ...

Using internet in retirement boosts cognitive function
Scientists have studied the effect of internet usage on cognitive function. Examining more than 2000 retirees from 10 European countries, researchers found that, on average, retirees who used the internet were able to recall 1.22 extra words in a recall test compared to non-internet users (which equates to performing around 8 per cent better in the tests). The effects were more significant in women, with female retirees who used the internet able to recall an additional 2.37 words, than peers who did not go online. Results also showed that retirees who used the internet were more likely to be male, were younger and better educated, and had been retired for less time. They were also found to be in better health - despite drinking and smoking more. mehr ...

Brain microstructural damage related to cognitive dysfunction and steroid medication in lupus patients
Researchers attempted to unravel such mechanisms by adopting non-invasive diffusion magnetic resonance imaging (MRI) to study the brains of SLE patients, particularly the white matter, coupled with computerized neuropsychological assessment. White matter lies beneath the grey matter cortex in the human brain and comprises millions of bundles of nerve fibers that transmit signals to different brain regions. mehr ...

Ancient DNA rewrites early Japanese history -- modern day populations have tripartite genetic origin
Researchers have extracted Ancient DNA from human bones to re-write early Japanese history by underlining that modern day populations in Japan have a tripartite genetic origin -- a finding that refines previously accepted views of a dual genomic ancestry. mehr ...

Time until dementia symptoms appear can be estimated via brain scan
Researchers have developed an approach to estimating when a person who is at high risk of Alzheimer's dementia but has no cognitive symptoms will start showing signs of cognitive decline. The approach is based on data from a single brain scan, combined with the person's age. mehr ...

Climatically driven landscape evolution during warm periods
Scientists have researched the stability and development of landscapes in the Wendland region of Hanover during the past Eemian Interglacial (warm period) around 120,000 years ago. The Eemian is climatically comparable to predictions for the later 21st century. The basic research therefore serves to understand how landscapes respond to climate changes under natural conditions -- without additional human influence. As part of their investigations, the researchers also found evidence of the northernmost Neanderthal occupation of the last warm period to date. mehr ...

How scents take on meaning
Once a scent is detected, different areas of the brain are activated. A team has recently discovered that structures of the olfactory sense work closely together with the brain's reward and aversion systems. This means that scents are processed not only by the olfactory center but also by regions responsible for emotions and valence determination. mehr ...

Ancient bone tools found in Moroccan cave were used to work leather, fur
When researchers first started to look at animal bones from Contrebandiers Cave, Morocco, they wanted to learn about the diet and environment of early human ancestors who lived there between 120,000 and 90,000 years ago. But they soon realized that the bones they had found weren't just meal scraps. They'd been shaped into tools, apparently for use in working leather and fur. mehr ...

Milk enabled massive steppe migration
The long-distance migrations of early Bronze Age pastoralists in the Eurasian steppe have captured widespread interest. But the factors behind their remarkable spread have been heavily debated by archaeologists. Now a new study provides clues regarding a critical component of the herders' lifestyle that was likely instrumental to their success: dairying. mehr ...

Protein from the liver may cause Alzheimer's disease in the brain, study finds
Amyloid protein made in the liver can cause neurodegeneration in the brain, according to a new study. Since the protein is thought to be a key contributor to development of Alzheimer's disease (AD), the results suggest that the liver may play an important role in the onset or progression of the disease. mehr ...

People synchronize heart rates while listening attentively to stories
People often unconsciously synchronize bodily functions like heartbeat and breathing when they share an experience, such as a live performance or have a personal conversation. According to a new study, subjects' heart rates synchronize even if they are just listening to a story by themselves, and this synchronization only occurs when the subjects are paying attention to the story. mehr ...
