A new study, which combines satellite thermal and in situ warming experiment data from across the world’s tropical forests, looks at the variation of leaf temperatures within forest canopies. The data collected revealed that a small percentage of tropical leaves are already reaching, and occasionally exceeding, the temperatures at which they can no longer function—suggesting that as climate change continues, entire canopies could die, eliminating a key regulator of Earth’s climate and putting the world’s biodiversity at risk.

A new study highlights the potential of artificial DNA structures that, when fitted with antibodies, instruct the immune system to specifically target cancerous cells.
Researchers from the National University of Singapore took a leaf out of nature’s book to develop ‘eAir’ — a novel pressure sensing technology that promises to transform minimally-invasive surgeries and implantable sensors. This novel invention mirrors the lotus leaf’s natural sensitivity to the extremely light touch of a water droplet, to achieve high accuracy and reliability in pressure detection.
Imagine a few roughly cut slices of bread on a plate. With just those slices, could you picture, in fine detail, the loaf they came from?
When choosing their behaviour in socially difficult situations, anxious people use a less suitable section of the forebrain than people who are not anxious.
Researchers from Washington University in St. Louis have used ultrasound to nudge rodents into an energy-conserving state that mirrors a natural, hibernation-like survival mechanism known as torpor. The technique could help buy precious time for patients in critical care.
St. Jude Children’s Research Hospital scientists found that immune cells present in individuals long before influenza infection predict whether the illness is symptomatic.
A research team co-led by UCLA investigators has shown that an immunotherapy drug combination can be an effective second-line therapy for patients with an aggressive and deadly type of melanoma that is resistant to the widely used immunotherapy drugs known as PD-1 inhibitors.
Researchers at Albert Einstein College of Medicine have found that the virus responsible for chikungunya fever can spread directly from cell to cell—perhaps solving the longstanding mystery of how the virus, now emerging as a major health threat, can manage to escape antibodies circulating in the bloodstream.
Addressing climate change isn't just a technical issue; it's a societal one. A recent article in Nature Energy highlights the increasing urgency for engineers and social scientists to combine their expertise.
The qubits that make up quantum computers have a lesser-known cousin called qudits. Qudits can carry more information and are more resistant to the noise that can cause qubits to lose information. However, qudits have historically been difficult for scientists to measure and modify.
Researchers used diamond mirrors to guide X-ray laser pulses around a rectangular racetrack inside a vacuum chamber. It’s an important step toward developing cavity-based X-ray free-electron lasers, or CBXFELs, to make X-ray laser pulses brighter and cleaner – more like regular lasers are today.

Researchers at Oak Ridge National Laboratory used neutrons and x-rays to draw a roadmap of every atom, chemical bond and electrical charge inside a key metabolic pathway in the body that cancer cells hijack and dramatically overuse to reproduce.

The drugs would be designed to target highly aggressive tumor-forming cancers that too often become terminal such as lung, colon, breast, pancreatic and prostate cancers.
