Pollution : New ammonia emission sources detected from space
Pollution : New ammonia emission sources detected from space
Paris, December 5, 2018 Researchers from the CNRS 1 and the Université Libre de Bruxelles (ULB) have prepared the first global map of the distribution of atmospheric ammonia (NH3) by analyzing measurements taken by satellites between 2008 and 2016. The IASI interferometer developed by the CNES allowed them to catalog more than 200 ammonia sources, two-thirds of which had never been identified before.

Whole-brain imaging of mice during behavior
In a study published in Neuron, researchers have demonstrated how functional ultrasound imaging can yield high-resolution, unbiased, brain-wide activity maps of behaving mice. These can lead to a brain-wide understanding of how brain activity relates to specific behavior - in healthy mice and in mouse models of neurologic or psychiatric diseases.

Study solves mystery of how geckos walk on water
It's official, the humble gecko is the Maserati of reptiles. Despite being just a few centimetres long, the gecko is known for its superior acrobatic skills and ability to power through the most challenging terrain, such as, climbing the tallest trees and running across cold, slippery ice. Scientists have now cracked perhaps its most head-scratching talent of all: how it walks on water.

UC San Diego Researchers Develop Sensors to Detect and Measure Cancer’s Ability to Spread
The spread of invasive cancer cells from a tumor's original site to distant parts of the body is known as metastasis. It is the leading cause of death in people with cancer. In a paper published online in iScience , University of California San Diego School of Medicine researchers reported engineering sensors that can detect and measure the metastatic potential of single cancer cells.

A microbe’s membrane helps it survive extreme environments
Scientists discovered a protein that modifies a microbe's membrane and helps it survive in hot, acidic environments, proving a long-standing hypothesis that these structures have a protective effect. Facebook Twitter Email The microorganism Sulfolobus acidocaldarius lives in extreme environments, such as Emerald Hot Spring in Yellowstone National Park.

Chopping unlocks new function in protein linked to dementia
Scientists have uncovered an unexpected new role for a protein that may underlie rare diseases. A protein, called p62, is chopped by molecular scissors to help cells realise that they are 'hungry', encouraging them to break down and consume old material in the cell. This helps them to stay healthy and fight off infection.

Marmoset study gives insights into loss of pleasure in depression
Marmoset study gives insights into loss of pleasure in depression
'Anhedonia' (the loss of pleasure) is one of the key symptoms of depression. An important component of this symptom is an inability to feel excitement in anticipation of events; however the brain mechanisms underlying this phenomenon are poorly understood.

Study counts the high cost of infidelity for swift parrots
Study counts the high cost of infidelity for swift parrots
Scientists at ANU have found a chronic shortage of females in a critically endangered parrot species has led to love triangles, sneaky sex on the side, increased fighting between males and fewer babies. The ratio of males to females among swift parrots was once roughly equal but it has increased over time to almost three to one, since the introduction of a tiny predator to Tasmania in the 1800s - the sugar glider.

Learning from Mistakes
Everyone makes little everyday mistakes out of habit-a waiter says, "Enjoy your meal," and you respond with, "You, too!" before realizing that the person is not, in fact, going to be enjoying your meal. Luckily, there are parts of our brains that monitor our behavior, catching errors and correcting them quickly.

Stentrode developed for brain treatments without major surgery
Stentrode developed for brain treatments without major surgery
Australian researchers have developed a tiny device that electrically stimulates the brain and could one day be used to treat conditions such as epilepsy and Parkinson's disease without invasive surgery. They have shown for the first time that electrical stimulation can be delivered into the brain from a 4 mm diameter Stentrode permanently implanted inside a blood vessel.

Clue to ecosystem recovery after pollution
Scientists have discovered a fish species which significantly evolved and expanded its ecological toolset, after an effort was made to reduce pollution in its ecosystem. The study, led by the University of Glasgow and the University of Konstanz and published in Nature Ecology and Evolution , found that the gangfisch - a European whitefish subspecies - expanded its genetic diversity after habitat loss and hybridization with other whitefish subspecies during eutrophication.

Are scientists studying the wrong kind of mice?
Mice represent well over half of the non-human subjects of biomedical research, and the vast majority of those mice are inbred. Formed by generation after generation of mating between brothers and sisters, inbred mice are genetically identical to each other, like twins or clones. Inbreeding is well known to reduce health and vigor across species; this biological fact is the reason that incest is a universal taboo.

No-Deal Brexit will severely impact NHS delivery across devolved jurisdictions -report reveals
Computer simulations of microscopic, protein-coated beads that block bacteria from binding to host cells suggest that the microbeads could help reduce or eliminate bacterial infections in burn wounds. Dr Paul Roberts from the University of Birmingham's School of Mathematics , UK., and colleagues present these new findings, funded by the BBSRC, in the journal PLOS Computational Biology.

Nature's 'laboratory' offers clues on how plants thrive through genetic diversity
PA 253/18 Scientists have turned to nature's own 'laboratory' for clues about how plants adapt in the environment to ensure their own survival. A study led by researchers at The University of Nottingham has suggested that while plants evolve to adapt to their conditions, they also maintain a small degree of diversity to stay one step ahead of changing conditions.

Nanoscale tweezers can perform single-molecule ’biopsies’ on individual cells
Using electrical impulses, the 'tweezers' can extract single DNA, proteins and organelles from living cells without destroying them. We are continuously expanding our knowledge on how cells function, but many unanswered questions remain. This is especially true for individual cells that are of the same type, such as brain, muscle or fat cells, but have very different compositions at the single-molecule level.

Simple yet powerful model predicts DNA organization
Stanford researchers built a computer model to simulate how DNA is packaged in the nucleus, allowing them to do computational experiments that would be impractical at the lab bench.

Genes tied to dementia in key early step toward new therapies
Genes tied to dementia in key early step toward new therapies
A UCLA-led research team has identified genetic processes involved in the neurodegeneration that occurs in dementia — an important step on the path toward developing therapies that could slow or halt the course of the disease. The findings appear today Medicine. The researchers discovered two major groups of genes involved in mutations that result in an overproduction of a protein called tau, a hallmark of the progressive loss of neurons seen in major forms of dementia.

New drug combination could be more effective against melanoma
New drug combination could be more effective against melanoma
Chemists discover an unexpected synergy between two types of cancer drugs. A class of cancer drugs called protein kinase inhibitors is one of the most effective treatments for melanoma. However, in many cases, tumors eventually become resistant to the drugs and cause a relapse in the patient. A new study from MIT suggests that combining kinase inhibitors with experimental drugs known as ribonucleases could lead to better results.
