Optogenetics makes sterile mice fertile again

Scientists from the Center of Advanced European Studies and Research (caesar) in Bonn, an Institute of the Max Planck Society, have succeeded for the first time in controlling the function of sperm by optogenetics. They inserted a light-activated enzyme for cAMP synthesis into mouse sperm that lacked the endogenous enzyme. Sperm of these mice are usually non-motile, and the mice consequently infertile. After stimulation of these sperm with blue light, they produce cAMP, start to swim again, and are even able to fertilise eggs. Using optogenetics, the scientists are now able to control not only the influx of ions into nerve cells, and thus their activity, but also signalling pathways in other cell types.

The intervention is performed at CHU Sainte-Justine by orthopedic surgeon Dr. Stefan Parent, who also carries research with the aim of identifying those children at-risk of major curvature progression who are likely to benefit from the new surgical technique. Straightening the spine by leveraging the child's growth

Men who live alone run a greater risk of dying prematurely after stroke

Men who live alone have a considerably greater long-term risk of dying prematurely than other patients. This is shown in a doctoral thesis that followed 1,090 stroke cases in western Sweden.

Tracking the flu with data

The Centers for Disease Control and Prevention recently declared a flu epidemic in the U.S., with the virus appearing in 46 states so far. Many people have stayed home sick, while officials have announced that this year's vaccine is not as effective as in years past. Alessandro Vespignani—a world-renowned statistical physicist and the Sternberg Distinguished Professor of Physics who holds joint appointments in the College of Science, the College of Computer and Information Science, and the Bouvé College of Health Sciences at Northeastern—and his team in the university's Laboratory for the Modeling of Biological and Socio-Technical Systems are utilizing large amounts of data to model the spread of the virus and predict when the outbreak will begin to taper off.

The results are published online January 19, 2015 in Nature Neuroscience.

Does gestational diabetes affect the therapeutic potential of umbilical cord-derived stem cells?

Multipotent cells isolated from the human umbilical cord, called mesenchymal stromal cells (hUC-MSCs) have shown promise for use in cell therapy to treat a variety of human diseases. However, intriguing new evidence shows that hUC-MSCs isolated from women with gestational diabetes demonstrate premature aging, poorer cell growth, and altered metabolic function, as reported in an article in Stem Cells and Development.

Patients actively warmed during surgery still experience hypothermia, study finds

Body temperature decreases during the first hour of surgery, even when patients are actively warmed with forced air, reports a new study published in the February issue of Anesthesiology, the official medical journal of the American Society of Anesthesiologists (ASA). Furthermore, patients who experience the most hypothermia are more likely to require blood transfusions.

ASCO names Cancer Advance of the Year

The American Society of Clinical Oncology (ASCO) for the first time announced its cancer Advance of the Year: the transformation of treatment for the most common form of adult leukemia. Until now, many patients with chronic lymphocytic leukemia (CLL) have had few effective treatment options. Four newly approved therapies, however, are poised to dramatically improve the outlook for patients with the disease.

High-dose statin may protect heart surgery patients' kidney health

Acute kidney injury often arises after major surgery because the kidneys can be deprived of normal blood flow during the procedure. The use of contrast media, or dyes, can contribute to this problem.

Staff at psychiatric hospitals often face threats of physical violence

In a survey of 348 workers at a large psychiatric hospital, 99% of the staff reported verbal conflict with patients, and 70% reported being assaulted during the previous 12 months. Verbal conflict with other staff was also high, at 92%.

Equation helps identify global disparities in cancer screening and treatment

Disparities in cancer screening, incidence, treatment, and survival are worsening globally. In a new study on colorectal cancer, researchers found that the mortality-to-incidence ratio (MIR) can help identify whether a country has a higher mortality than might be expected based on cancer incidence.

Hearing-aid intervention helps individuals gradually adjust to devices

When individuals wear their hearing aids for the first time, they are flooded with sounds they have not heard in months or years; yet, previous research has shown that not all new sounds are welcomed. Ambient noises such as air conditioners, wind and background conversations can be painful, irritating and difficult to ignore, causing some individuals to stop using their hearing aids right away. Now, a University of Missouri researcher has developed an intervention that helps older adults gradually increase their hearing-aid use and satisfaction with the devices.

VA settles more retaliation complaints by whistleblowers

The Veterans Affairs Department said Tuesday it is offering relief to more than two dozen employees who faced retaliation after filing whistleblower complaints about wrongdoing at VA hospitals and clinics nationwide.

Education aids understanding, reduces stigma of facial paralysis, study shows

A little bit of sensitivity training can help people form better first impressions of those with facial paralysis, reducing prejudices against people with a visible but often unrecognizable disability, new research from Oregon State University indicates.

Metabolic enzyme is upregulated in patients with non-small cell lung cancer

The majority of lung cancers are classified as non-small cell lung cancer (NSCLC). Even with early detection, the 5-year survival rate for patients with NSCLC is less that 50%. Compared to the surrounding tissue, cancer cells have increased energy demands to maintain rapid proliferation. Cancer cells have been shown to alter their metabolic profile to meet the increased demand in energy.

Use of sedation protocol does not reduce time on ventilator for children

Among children undergoing mechanical ventilation for acute respiratory failure, the use of a nurse-implemented, goal­directed sedation protocol compared with usual care did not reduce the duration of mechanical ventilation, according to a study appearing in JAMA.

Harnessing data from Nature's great evolutionary experiment

There are 3 billion letters in the human genome, and scientists have endlessly debated how many of them serve a functional purpose. There are those letters that encode genes, our hereditary information, and those that provide instructions about how cells can use the genes. But those sequences are written with a comparative few of the vast number of DNA letters. Scientists have long debated how much of, or even if, the rest of our genome does anything, some going so far as to designate the part not devoted to encoding proteins as "junk DNA."

Predators, parasites, pests and the paradox of biological control

When a bird swoops down and grabs a caterpillar devouring your backyard garden, you might view it as a clear victory for natural pest control.

Study shows lions got distemper from dogs originally but now there are other carriers

(Phys.org)—A study conducted by an international team of researchers has led to evidence that suggests lions in Africa originally got distemper from domesticated dogs, but now it appears there are other unknown carriers. In their paper published in Proceedings of the National Academy of Sciences the team explains the data analysis they undertook covering distemper infections in a park in Tanzania, and how their findings help better understand how infectious diseases jump between species.

Caring and sharing is monkey business

Chimpanzees, much like children, can learn to be kind by observing and experiencing the kindness of others, according to new research by the University of St Andrews.

Implanting complex multimodal fibers into the spinal column

The human brain's complexity makes it extremely challenging to study—not only because of its sheer size, but also because of the variety of signaling methods it uses simultaneously. Conventional neural probes are designed to record a single type of signaling, limiting the information that can be derived from the brain at any point in time. Now researchers at MIT may have found a way to change that.

The importance of the position of cell nuclei for a correctly formed retina

We perceive our environment mostly with our eyes: the visual system delivers about 80 percent of the information processed in the brain. The retina contains all the neurons responsible for transmitting visual information to the brain. At the Max Planck Institut of Molecular Cell Biology and Genetics, scientists discover the importance of the position of cell nuclei for a correct formed retina.

New method for analysing RNA sequence data identifies new subtypes of cells

A new method for analysing RNA sequence data allows researchers to identify new subtypes of cells, creating order out of seeming chaos. Published in Nature Biotechnology, the novel technique developed by scientists at The European Molecular Biology Laboratory's European Bioinformatics Institute (EMBL-EBI) represents a major step forward for single-cell genomics.

Burying beetles hatch survival plan to source food, study shows

Young beetles pick up sensory signals from adult insects to increase their chances of being fed - and shorten the odds of being killed instead.

Living longer, not healthier

A study of long-lived mutant C. elegans by scientists at the University of Massachusetts Medical School shows that the genetically altered worms spend a greater portion of their life in a frail state and exhibit less activity as they age then typical nematodes. These findings, published in the Proceedings of the National Academy of Sciences, suggest that genes that increase longevity may not significantly increase healthy lifespan and point to the need to measure health as part of aging studies going forward.

Scientists identify important mechanism involved in production of mosquito eggs

Diseases transmitted by mosquitoes have contributed to the death and suffering of millions throughout human history, earning the mosquito the title as the world's most dangerous animal. Even today, several devastating mosquito-borne diseases (such as malaria, dengue fever and West Nile virus) continue to rage.

India's tiger population jumps

India, home to most of the world's wild tigers, on Tuesday reported a 30 percent jump in numbers over four years in a rare piece of good news for conservationists.

Are Asian citrus psyllids afraid of heights? New study may provide clues for stopping them

The Asian citrus psyllid, Diaphorina citri, was first discovered in Florida in 2005 and in Puerto Rico in 2007. Since then it has caused billions of dollars' worth of damage by spreading a bacterium which is responsible for citrus greening disease (Huanglongbing), the most serious disease of citrus in the world. However, scientists from Puerto Rico and Florida have discovered that the ACP doesn't do well at high elevations for reasons that are not yet known. Their research, which may one day lead to clues about the insect's vulnerabilities, is published in the Journal of Economic Entomology.

Lab develops protein-based vaccine for insect-borne virus

Vaccines developed using proteins rather than live viruses can help protect animals and subsequently humans from insect-borne viruses, according to Alan Young, chief scientific officer for Medgene Labs, an animal health company that develops therapeutics and diagnostics, including vaccines.

New research finds Takahe have African cousins

New research from Massey University suggests that our Takahē have African cousins and that our Pūkeko are getting friendly with their Australian counterparts.

Twist1: Complex regulator of cell shape and function

Transcription factor Twist1 is involved in many processes where cells change shape or function. Thereby, Twist1 is crucial for embryonic development, but has also been implicated in cancer progression. However, the precise contribution of Twist1 to these processes is under much debate. Scientists from the Helmholtz Zentrum München describe a new mode of action: a short-term, transient activation of Twist1 primes cells for stem cell-like properties. By contrast, prolonged, chronic Twist1 activity suppresses stem cell-like traits. These results, published in the journal Cell Reports, help to unravel seemingly contradictory observations and illuminate the complexities of transcription factor action in regeneration and tumor progression.

Silk-weaving ant study sees new behavior

A James Cook University Professor's study of silk-weaving ants is promising to change our understanding of how all creatures work together.

Saving the little Aussie battler

Drugs from dirt: Scientists develop first global roadmap for drug discovery

Rockefeller University scientists have analysed soils from beaches, forests, and deserts on five continents and discovered the best places in the world to mine untapped antibiotic and anticancer drugs. The findings, published in the open-access journal eLife, provide new insights into the natural world as well as a road map for future drug discovery. The scientists now want to collect more samples from unique environments such as caves, hot springs, islands and city parks. They will continue with their citizen science effort, Drugs from Dirt, inviting the public to submit samples.

Climate change does not bode well for picky eaters

In a part of the world that is experiencing the most dramatic increase in temperature and climate change, two very similar species of animals are responding very differently. New research published today suggests that how these species have adapted to co-exist with one another might be to blame.

Mapping the maize genome

Positional cloning is a genetic mapping technique used to pinpoint the location of specific traits of interest, such as disease-causing genes or mutations, within the genome. Very simply, this map-based technique involves crossing mutant individuals with wild-type individuals and examining the offspring in order to localize a candidate region in the genome for the mutation. By identifying genetic markers that are linked to the trait, progressively more precise areas on a chromosome are defined until the gene is identified.

Mysterious goo blamed in San Francisco Bay Area bird deaths

The death of 100 birds in the San Francisco Bay Area has baffled wildlife officials who say the creatures' feathers were coated with a mysterious substance that looks and feels like rubber cement.

A chemical modified version of the second messenger cAMP

Second messengers are small molecules that transmit signals in the cell. A single second messenger typically interacts with several signalling proteins. "Even though this may give the impression of promiscuity, the interactions are in fact highly specific" Assistant Professor Rehmann from the University Medical Center Utrecht explains. "It is just that one second messenger functions in multiple signalling pathways. This is not a problem, as its concentration is tightly controlled. But it probably turns into a problem if we would flood the body with a drug just mimicking this second messenger. What we need is a drug influencing only one process."

'Citizen science' reveals positive news for Puget Sound seabirds

A new analysis of seven years of bird sightings by volunteer birdwatchers from the Seattle Audubon Society has found positive trends in several Puget Sound seabird species that had been in historic decline.

Biggest fish in the ocean receives international protection

Whale sharks are among the largest living fish in the world - weighing up to 40,000 pounds and 40 feet in length. They are also so docile that humans often swim with them without concern, snapping photographs of their incredible size.

Organic and conventional milk—comparing apples to apples?

Consumers perceive that organic cow milk differs from conventionally produced milk and that these differences justify the premium price for organic milk. In a review published in the Journal of Dairy Science, researchers in New Zealand found that the differences between organic and conventional milk are not so straightforward.

In the face of imminent arrival of avocado plague, scientist undertake preventive measures

From Asia, the red ambrosia beetle (Xyleborus glabratus) has proved its damaging potential in Florida, where it attacked different varieties of trees of the laurel family, including avocado, resulting in death.
