Discovery of kidney structure challenges current understanding of renal physiology
Discovery of kidney structure challenges current understanding of renal physiology
New research by the University of Bristol has found that the microscopic structure of human kidney is different to what was previously known. The kidney is a key organ balancing blood and body chemistry through filtration and reabsorption. The control of blood flow and pressure through the kidney is crucial for maintaining this process.

Tracking cancer-cell development with "drinkable" electronic sensors
Thanks to an unorthodox approach being proposed by EPFL researchers, patients may soon be able to track their illness simply by drinking a solution containing millions of tiny electronic sensors disguised as bacteria. Imagine being able to track the development of diseased cells in real time, simply by having patients drink a glass of water containing millions of tiny electronic biosensors.

New insights into DNA ’melting’ reveal chink in bacteria’s armour
Scientists have shed light on DNA 'melting' - a crucial process fundamental to all life. The researchers, from Imperial College London , who used bacteria in their experiments, say these findings may provide new insights into eradicating harmful bugs. How DNA melts is a fundamental part to all life - bacterial and human Professor Xiaodong Zhang Study author DNA encodes information When a cell wants to make proteins, the strands need to be pulled apart or 'melted' first, before a fundamental cellular process called transcription takes place.

Dynamic modeling helps predict the behaviors of gut microbes
The human gut is teeming with microbes, each interacting with one another in a mind-boggling network of positive and negative exchanges. Some produce substances that serve as food for other microbes, while others produce toxins - antibiotics - that kill their neighbors. Scientists have been challenged trying to understand how this collection of gut microbes known as the microbiome is formed, how it changes over time and how it is affected by disturbances like antibiotics used to treat illnesses.

Carnegie Mellon Neuroscientists Map Brain’s Response to Cold Touch
Carnegie Mellon University neuroscientists have mapped the feeling of cool touch to the brain's insula in a mouse model. The findings, published in the June 15 issue of Journal of Comparative Neurology , provide an experimental model that will advance research into conditions like pain and hypersensitivity to cold and help researchers to continue to unravel the multifaceted ways touch is represented in the brain.

New gibbon genus discovered in ancient Chinese tomb
New gibbon genus discovered in ancient Chinese tomb
Bones of an entirely new but already extinct genus of gibbons have been discovered in China, revealing the magnitude of human-caused extinction of primates, according to a study by UCL and ZSL (Zoological Society of London). The discovery was made by scientists while studying the contents of a burial chamber in Shaanxi Province, central China and The ancient tomb dates from around 2,300 years ago and possibly belonged to Lady Xia - grandmother to China's first emperor, Qin Shihuang, the leader who ordered the building of the Great Wall of China and the Terracotta Warriors.

Fat cells control fat cell growth
Fat cells control fat cell growth
Researchers from ETH Zurich and EPFL have discovered a new type of fat cell that suppresses the growth of new fat cells. This opens up new avenues for preventing obesity-related diseases. Obesity is the plague of our times. Some 80 percent of obese people will develop Type 2 diabetes at some point in their lives, and being overweight is also a significant risk factor for cancer and heart attacks.

The cells that control the formation of fat
The cells that control the formation of fat
A study led by researchers in Switzerland has revealed a new cell type that resides in the body's fat depots where it can actively suppress fat cell formation. This discovery was made using single-cell transcriptomics and opens entirely new avenues to combat obesity and related diseases such as diabetes.

Producing sensors with an inkjet printer
Producing sensors with an inkjet printer
Research news Microelectrodes can be used for direct measurement of electrical signals in the brain or heart. These applications require soft materials, however. With existing methods, attaching electrodes to such materials poses significant challenges. A team at the Technical University of Munich (TUM) has now succeeded in printing electrodes directly onto several soft substrates.

Pancreatic tumors lead to weight loss
Pancreatic tumors lead to weight loss
Patients with pancreatic cancer usually experience significant weight loss, which can begin very early in the disease. A new study from MIT and Dana-Farber Cancer Institute offers insight into how this happens, and suggests that the weight loss may not necessarily affect patients' survival. In a study of mice, the researchers found that weight loss occurs due to a reduction in key pancreatic enzymes that normally help digest food.

Climate change to overtake land use as major threat to global biodiversity
Climate change to overtake land use as major threat to global biodiversity
Climate change will have a rapidly increasing effect on the structure of global ecological communities over the next few decades, with amphibians and reptiles being significantly more affected than birds and mammals, a new report by UCL finds. The pace of change is set to outstrip loss to vertebrate communities caused by land use for agriculture and settlements, which is estimated to have already caused losses of over ten per cent.

Artificial intelligence reveals authors of anonymous 19th-century texts on evolution
Introduction: With the help of modern AI software, Koen Tanghe (UGent) and Mike Kestemont (UAntwerpen) have revealed the authors of two early papers on evolution. Some anonymously published papers on evolution far predate the publication of Charles Darwin's Origin of Species (1859). With the help of modern AI software, Koen Tanghe (UGent) and Mike Kestemont (UAntwerpen) have revealed the authors of two of these papers.

A dual-therapy approach to boost motor recovery after a stroke
A dual-therapy approach to boost motor recovery after a stroke
EPFL scientists have shown that combining a brain-computer interface (BCI) with functional electrical stimulation (FES) can help stroke victims recover greater use of their paralyzed arm - even years after the stroke. Paralysis of an arm and/or leg is one of the most common effects of a stroke.

Computational Method Puts Finer Point on Multispecies Genomic Comparisons
Probabilistic model could provide insights into what makes a human a human A new computational tool will potentially help geneticists to better understand what makes a human a human, or how to differentiate species in general, by providing more detailed comparative information about genome function.

Study confirms beetles exploit warm winters to expand range
Study confirms beetles exploit warm winters to expand range
The study, published in Global Change Biology, is the first of its scope, encompassing a nine-year dataset sampling 10,000 trees across 22 million acres. Both competition and winter cold are known to be important causes of mortality, but no previous studies addressed how these mortality factors interact.

ESA Space in Images Have you ever considered yourself capable of manipulating gravity? When you grip an object, you are doing just that. Gravity is constantly exerting its force on objects, most notably by keeping everything weighed down. But when you lift a cup to your mouth, you are playing against gravity.

Palm oil: the carbon cost of deforestation
Palm oil: the carbon cost of deforestation
Palm oil has become part of our daily lives, but a recent study by EPFL and the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) serves as a reminder that intensive farming of this crop has a major impact on the environment. Both shortand long-term solutions exist, however. Indonesia and Malaysia together account for nearly 85% of global palm oil production.

Is the sky the limit?
Is the sky the limit?
What stops a species adapting to an ever-wider range of conditions, continuously expanding its geographic range? The biomathematician Jitka PolechovŠ, an Elise Richter Fellow at the University of Vienna, has published a paper in PLoS Biology which explains the formation of species' range margins. The theory shows that just two compound parameters, important for both ecology and evolution of species, are fundamental to the stability of their range: the environmental heterogeneity and the size of the local population.
