Early trauma cuts life short for squirrels, and climate change could make matters worse

2:54
Life can be tough for young red squirrels living in the Canada's Yukon territory, where frigid winters, food scarcity and predators threaten their long-term survival. Scientists want to know what factors might protect young squirrels, especially as their environment becomes more impacted by climate change.

Voluntary corporate emissions targets not enough to create real climate action

2:54
Companies' emissions reduction targets should not be the sole measure of corporate climate ambition, according to a new perspective paper.

Advanced cell atlas opens new doors in biomedical research

2:54
Researchers have developed a web-based platform that offers an unprecedented view of the human body at the cellular level. The aim is to create an invaluable resource for researchers worldwide to increase knowledge about human health and disease.

Food in sight? The liver is ready!

1:49
What happens in the body when we are hungry and see and smell food? A team of researchers has now been able to show in mice that adaptations in the liver mitochondria take place after only a few minutes. Stimulated by the activation of a group of nerve cells in the brain, the mitochondria of the liver cells change and prepare the liver for the adaptation of the sugar metabolism. The findings could open up new avenues for the treatment of type 2 diabetes.

Curiosity promotes biodiversity

1:49
Cichlid fishes exhibit differing degrees of curiosity. The cause for this lies in their genes, as reported by researchers. This trait influences the cichlids' ability to adapt to new habitats.

National trial safely scaled back prescribing of a powerful antipsychotic for the elderly

1:17
Warning letters can safely cut prescribing of a powerful but risky antipsychotic, according to a new study. Researchers used Medicare data to study the effects of the letters on hundreds of thousands of older adults with dementia. They found a significant and lasting reduction in prescribing but no signs of adverse effects on patient health.

Use of acid reflux drugs linked to higher risk of migraine

1:17
People who take acid-reducing drugs may have a higher risk of migraine and other severe headache than people who do not take these medications, according to a new study. The acid-reducing drugs include proton pump inhibitors such as omeprazole and esomeprazole, histamine H2-receptor antagonists, or H2 blockers, such as cimetidine and famotidine, and antacid supplements.

A closed-loop drug-delivery system could improve chemotherapy

1:17
To improve chemotherapy dosing, engineers designed CLAUDIA, a way to continuously measure how much drug is in a patient's system during hours-long infusion.

Scientists tune the entanglement structure in an array of qubits

1:17
A new technique can generate batches of certain entangled states in a quantum processor. This advance could help scientists study the fundamental quantum property of entanglement and enable them to build larger and more complex quantum processors.

After spinal cord injury, neurons wreak havoc on metabolism

1:17
Conditions such as diabetes, heart attack and vascular diseases commonly diagnosed in people with spinal cord injuries can be traced to abnormal post-injury neuronal activity that causes abdominal fat tissue compounds to leak and pool in the liver and other organs, a new animal study has found.

Network model unifies recency and central tendency biases

0:46
Neuroscientists have revealed that recency bias in working memory naturally leads to central tendency bias, the phenomenon where people's (and animals') judgements are biased towards the average of previous observations. Their findings may hint at why the phenomenon is so ubiquitous.

Scientists identify and show how to target a key tumor defense against immune attack

0:46
A new study has discovered how a lipid molecule found at high levels within tumors undermines the anti-cancer immune response and compromises a recently approved immunotherapy known as adoptive cell therapy (ACT) using tumor infiltrating lymphocytes, or TIL-ACT.

Can climate change accelerate transmission of malaria? Pioneering research sheds light on impacts of temperature

0:46
A groundbreaking study combined novel experimental data within an innovative modeling framework to examine how temperature might affect transmission risk of malaria in different environments in Africa.

Cells may possess hidden communication system

0:46
Cells constantly navigate a dynamic environment, facing ever-changing conditions and challenges. But how do cells swiftly adapt to these environmental fluctuations? A new study is answering that question by challenging our understanding of how cells function. A team of researchers suggests that cells possess a previously unknown information processing system that allows them to make rapid decisions independent of their genes.
