The hunger games
The hunger games
Why do primates have big brains? In the Panamanian rainforest, scientists pitted large-brained primates against smaller-brained mammals to find out who was the smartest forager Primates, including humans, have larger brains than most other mammals, but why? Scientists searching for the answer have long followed a trail pointing to diet-specifically fruit-as the reason for why primates evolved larger brains.

A key protein preserves motor ability during aging
A new study by scientists shows that age-related decline in motor ability can be countered in fruit flies by enhancing the expression of the protein Trio, suggesting potential treatments for age-related movement decline. As we age, we suffer a noticeable decline in motor ability, which affects our quality of life and independence.

New research from the RVC unlocks the key to hummingbird flight
New research from the Royal Veterinary College (RVC), UCLA and the University of British Columbia has found that hummingbirds create a 3D map of their body, which may enable them to hover and make nuanced adjustments to their flight dynamics based on the smallest of touches and airflow in their environment.

Scientists identify mechanism behind drug resistance in malaria parasite
SMART researchers find a cellular process called transfer ribonucleic acid (tRNA) modification influences the malaria parasite's ability to develop resistance. Researchers from the Singapore-MIT Alliance for Research and Technology (SMART), in collaboration with MIT, Columbia University Irving Medical Center, and Nanyang Technological University in Singapore (NTU Singapore), have discovered a new link between malaria parasites' ability to develop resistance to the antimalarial artemisinin (ART) through a cellular process called transfer ribonucleic acid (tRNA) modification.

Cancer Research: DNA Repair Mechanism Further Elucidated
Cancer Research: DNA Repair Mechanism Further Elucidated
Researchers at the University of Würzburg, led by Caroline Kisker in cooperation with Claudia Höbartner, discovered how the protein XPD detects a severe DNA damage and controls its repair. The XPD protein is a central component of our body's own 'DNA repair team', known as nucleotide excision repair (NER).

Sanfilippo syndrome: Major advancement towards developing a treatment
For the first time, a team co-led by Alexey Pshezhetsky resolved the structure of the enzyme deficient in Sanfilippo disease, a rare pediatric neurodegenerative disorder. For the first time, a team co-led by CHU Sainte-Justine researcher and professor in the Faculty of Medicine at Université de Montréal, Alexey Pshezhetsky has succeeded in resolving the unique structure of the HGSNAT enzyme, a deficiency of which causes Sanfilippo syndrome, a rare pediatric disease affecting the central nervous system.

Cultural Networks of Central African Hunter-Gatherers Have Ancient Origin
Cultural Networks of Central African Hunter-Gatherers Have Ancient Origin
Extensive social networks between different hunter-gatherer groups in the Congo Basin existed long before agriculture arrived in the region. This continent-wide exchange preserved a cultural diversity that evolved thousands of years ago, as researchers from the University of Zurich show based on musical instruments, specialized vocabulary and genetic information.

Alzheimer’s disease risk: hyperactivation of memory circuits
By exploring the effects of sport on memory, scientists from the University of Geneva have discovered compensatory mechanisms in the brains of young individuals at genetic risk of developing Alzheimer's disease. The benefits of physical activity on health are widely accepted, and those on cognitive capacity are increasingly well known.

How and why different cell division strategies evolve
How and why different cell division strategies evolve
Scientists, in collaboration with researchers at EMBL Heidelberg, have discovered that a group of marine protists (eukaryotic organisms) closely related to animals use open or closed mitosis based on their life cycle stages, suggesting that the way animal cells perform cell division evolved long before animals themselves.

Imperceptible sensors made from 'electronic spider silk' can be printed directly on human skin
Imperceptible sensors made from ’electronic spider silk’ can be printed directly on human skin
Researchers have developed a method to make adaptive and eco-friendly sensors that can be directly and imperceptibly printed onto a wide range of biological surfaces, whether that's a finger or a flower petal. The method, developed by researchers from the University of Cambridge, takes its inspiration from spider silk, which can conform and stick to a range of surfaces.

Physical frailty may put people at greater risk of depression
The findings of a new Yale study suggest physical frailty may be a risk factor for depression - and a target for intervention. Individuals who meet at least one of the criteria for physical frailty are at higher risk of also developing depression, a new Yale study finds. The findings - which also include insights into the specific inflammatory molecules and changes in brain structure that could underlie this association between frailty and depression - point to a need for routine assessment of physical frailty in clinical practice, researchers said.

Sequencing of the developing human brain uncovers hundreds of thousands of new gene transcripts
New study could improve the ability to make genetic diagnoses and treat neurodevelopmental disorders Health + Behavior New study could improve the ability to make genetic diagnoses and treat neurodevelopmental disorders Key takeaways Regulation of isoforms - varied versions of RNA and proteins that can be produced from a single gene - is a critical tool in understanding brain development and genetic risk for neuropsychiatric disorders.

New Insights Into the Evolution of the Prion Protein
New Insights Into the Evolution of the Prion Protein
A study from Bochum describes a mammal-specific domain of the prion protein and offers new approaches for research into neurodegenerative diseases. At first, they cause memory deficits and difficulties in walking, finally they inhibit elementary motor skills and destroy basic brain functions: Prion diseases are progressive and invariably fatal neurodegenerative diseases.

Genetic risk scores for Parkinson’s for precision medicine approach
An interdisciplinary team from the Luxembourg Centre for Systems Biomedicine (LCSB) at the University of Luxembourg, together with international collaborators, established that a combination of small variations in genes regulating mitochondria, an important component of human cells, is associated with a higher risk for Parkinson's disease.

Mechanobiology exerts creative pressure
Mechanobiology exerts creative pressure
Numerous cellular phenomena are guided by mechanical forces, such as embryonic development or the spread of metastases. These phenomena are the subject of intense research aimed at understanding how they are translated into biological processes. Particular emphasis is being placed on new opportunities to treat diseases as resistant as cancer or fibrosis.

Excavation reveals ’major’ ancient migration to Timor Island
The discovery of thousands of stone artefacts and animal bones in a deep cave on Timor Island has led archaeologists to reassess the route that early humans took to reach Australia. Researchers from The Australian National University (ANU), Flinders University, University College London (UCL) and the ARC Centre of Excellence for Australian Biodiversity and Heritage dated and analysed the artefacts and sediment at the Laili rock shelter in central-north Timor-Leste, north of Australia, to pinpoint the arrival of the colonists.

Study explains why the brain can robustly recognize images, even without color
Study explains why the brain can robustly recognize images, even without color
The findings also reveal why identifying objects in black-and-white images is more difficult for individuals who were born blind and had their sight restored. Even though the human visual system has sophisticated machinery for processing color, the brain has no problem recognizing objects in black-and-white images.

Understanding why autism symptoms sometimes improve amid fever
With support from The Marcus Foundation, an MIT neuroscientist and a Harvard Medical School immunologist will study the "fever effect" in an effort to devise therapies that mimic its beneficial effects. Scientists are catching up to what parents and other caregivers have been reporting for many years: When some people with autism spectrum disorders experience an infection that sparks a fever, their autism-related symptoms seem to improve.
