Human bipedalism — walking upright on two legs — may have evolved in trees, and not on the ground as previously thought, according to a new study.

People with cluster headaches may be more than three times more likely to have other medical conditions such as heart disease, mental disorders and other neurologic diseases, according to a new study.

Two randomized, placebo-controlled trials evaluating three Ebola vaccine administration strategies in adults and children found that all the regimens were safe in both age groups, according to new results. Antibodies were produced in response to the va…

A new study reports the identification of a previously unknown genetic cause of a late-onset cerebellar ataxia, a discovery that will improve diagnosis and open new treatment avenues for this progressive condition.

Researchers have found a method using molecular profiling and machine learning to develop blood-based dietary signatures that more accurately assess diet and predict the risk of cardiovascular disease and type 2 diabetes. They say the metabolic snapsho…

Sediment cores obtained from Eifel maar sites provide insight into the presence of large Ice Age mammals in Central Europe over the past 60,000 years: Overkill hypothesis not confirmed. Herds of megafauna, such as mammoth and bison, have roamed the pre…

Two seemingly different areas of physics are related in subtle ways: Quantum theory and thermodynamics. How can the laws of thermodynamics arise from the laws of quantum physics? This question has now been pursued with computer simulations, which showe…

Researchers have developed a strategy for assessing the toxicity of chemicals using machine learning. The models developed in this study can lead to substantial improvements when compared to conventional ‘in silico’ assessments based on Quantitative St…

Viruses can inflame and disrupt connections between the olfactory system, which governs the sense of smell, and the part of the brain associated with memory and learning, possibly accelerating the onset of Alzheimer’s disease, according to a new study.

Researchers found that treating patients who have resectable malignant pleural mesothelioma, meaning that their tumor can be removed with surgery, with immunotherapy ahead of surgery resulted in favorable clinical outcomes.

Scientists have developed a machine learning model that uses the assortment of microbes found in wastewater to tease out how many individual people they represent.

Patients with treatment resistant depression have a 23 per cent higher risk of death than other depressed patients. They also have twice as much outpatient care and spend three times the number of days in inpatient care.

Some species of gut-dwelling bacteria activate nerves in the gut to promote the desire to exercise, according to a study in mice. The study reveals the gut-to-brain pathway that explains why some bacteria boost exercise performance.

Using cryogenic electron microscopy, a research team has revealed, for the first time, the structures and binding environments of pigments bound to a protein called a photosynthetic antenna of the marine green macroalga Codium fragile. The team’s resul…

Three approaches with a reputation for slowing aging processes have proven largely ineffective. For their study, researchers developed a new method to measure aging, which accounts for the complexity of aging in organisms.

Alzheimer’s disease (AD) is the fifth leading cause of death in adults over 65 years old. While many potential treatments for the neurodegenerative disease focus on developing drugs to target key culprits, a relatively new approach aims to more directl…

After an intermittent fasting diet intervention, patients achieved complete diabetes remission, defined as an HbA1c (average blood sugar) level of less than 6.5% at least one year after stopping diabetes medication, according to a new study.

Humans are living further and further away from nature, leading to a decline in the number of our interactions with nature. The researchers highlight that human experience of nature is crucial for developing pro-environmental behavior and thus facing t…

A single bout of exercise has been shown to elevate anti-cancer proteins called myokines in people with advanced prostate cancer, to levels which can significantly suppress tumour growth.

Inadequate pollination has led to a 3-5% loss of fruit, vegetable, and nut production and an estimated 427,000 excess deaths annually from lost healthy food consumption and associated diseases, including heart disease, stroke, diabetes, and certain can…
