A new study suggests eastern wild turkeys in five southern U.S. states are unlikely to make meaningful changes in the timing of when they begin nesting, even under significant future climate change. The findings suggest eastern wild turkeys (Meleagris gallopavo silvestris) could be vulnerable to shifts in climate, which could threaten the availability of their food sources, the amount of vegetation cover available to protect them from predators, and other factors. “There are implications here for turkey populations ...

Although wheat was among the first domesticated food crops, it remains a global dietary staple several millennia later. Grown on every continent except Antarctica, wheat is the second highest produced grain worldwide, with nearly 800,000 metric tons grown each year (Food and Agriculture Organization). However, a fungal pathogen named Fusarium graminearum causes the devastating disease Fusarium head blight (FHB) on wheat and contaminates grains with harmful toxins called trichothecenes. One such trichothecene, called deoxynivalenol (DON), is produced by most F. graminearum strains in the United States, and it is an essential virulence factor that increases the pathogen’s spread ...

Currently, there is no cure for amyloidosis, a life-threatening disease that can be present throughout the body, including the heart, kidneys, liver and brain. The most common localized form of amyloidosis, which is seen significantly more often, is in the brain. Cerebral amyloidosis, when symptomatic, usually manifests in one of two ways: in Alzheimer’s disease and related dementias and in brain bleeds, which have consequences such as a stroke. Because amyloidosis does not affect a specific organ, unraveling the underlying cause of amyloid fibril creation – a hallmark ...

A University of Minnesota Twin Cities team has, for the first time, synthesized a thin film of a unique topological semimetal material that has the potential to generate more computing power and memory storage while using significantly less energy. The researchers were also able to closely study the material, leading to some important findings about the physics behind its unique properties. The study is published in Nature Communications, a peer-reviewed scientific journal that covers the natural sciences and engineering. As evidenced by the United States’ recent CHIPS and Science Act, there is a growing need to increase semiconductor manufacturing ...

Researchers at University of Michigan developed a method to produce artificially grown miniature brains — called human brain organoids — free of animal cells that could greatly improve the way neurodegenerative conditions are studied and, eventually, treated. Over the last decade of researching neurologic diseases, scientists have explored the use of human brain organoids as an alternative to mouse models. These self-assembled, 3D tissues derived from embryonic or pluripotent stem cells ...

Averting our eyes from things that scare us may be due to a specific cluster of neurons in a visual region of the brain, according to new research at the University of Tokyo. Researchers found that in fruit fly brains, these neurons release a chemical called tachykinin which appears to control the fly’s movement to avoid facing a potential threat. Fruit fly brains can offer a useful analogy for larger mammals, so this research may help us better understand our own human reactions to scary situations and phobias. Next, the team want to find out how these ...

(Santa Barbara, Calif.) – ​​Rising ocean temperatures are sweeping the seas, breaking records and creating problematic conditions for marine life. Unlike heatwaves on land, periods of abrupt ocean warming can surge for months or years. Around the world these ‘marine heatwaves’ have led to mass species mortality and displacement events, economic declines and habitat loss. New research reveals that even areas of the ocean protected from fishing are still vulnerable to these extreme events fueled by climate change. A study published today in Global Change Biology, led by researchers at UC Santa ...

A collaboration of scientists from The University of Manchester and the University of Hong Kong have found a source for the mysterious alignment of stars near the Galactic Centre. The alignment of planetary nebulae was discovered ten years ago by a Manchester PhD student, Bryan Rees, but has remained unexplained. New data obtained with the European Southern Observatory Very Large Telescope in Chile and the Hubble Space Telescope, published in Astrophysical Journal Letters, has confirmed the alignment but also found a particular ...

Defying conventional wisdom, researchers have uncovered a novel coupling mechanism involving leaky mode, previously has been considered unsuitable for high-density integration in photonic circuits. This unexpected finding opens new possibilities for dense photonic integration, revolutionizing the scalability and application of photonic chips in optical computing, quantum communication, light detection and ranging (LiDAR), optical metrology, and biochemical sensing.   In a recent Light Science & Application publication, Sangsik Kim, associate professor of electrical engineering ...

A study examining unemployment and underemployment figures and suicide rates in Australia has found both were significant drivers of suicide mortality between 2004-2016. The researchers say the findings indicate that economic policies such as a Job Guarantee, which prioritise full employment, should be a core part of any comprehensive national suicide prevention strategy. Predictive modelling also revealed an estimated 9.5 percent of suicides reported during that time resulted directly from unemployment ...

Mycelium, an incredible network of fungal strands that can thrive on organic waste and in darkness, could be a basis for sustainable fireproofing. RMIT researchers are chemically manipulating its composition to harness its fire-retardant properties. Associate Professor Tien Huynh, an expert in biotechnology and mycology, said they’ve shown that mycelium can be grown from renewable organic waste. “Fungi are usually found in a composite form mixed with residual feed material, but we found a way to grow pure mycelium sheets that can be layered and engineered into different uses – from flat panels for the building industry to a leather-like material for ...

The structure of a molecular junction with noncovalent interaction plays a key role in electron transport, reveals a recent study conducted by researchers at Tokyo Tech. Through simultaneous surface-enhanced Raman scattering and current–voltage measurements, they found that a single dimer junction of naphthalenethiol molecule shows three different bondings, namely π–π intermolecular and through-π and through-space molecule–electrode interactions. The π–π interaction is a type of noncovalent interaction that occurs when the electron clouds in the π orbitals ...

New research suggests that targeting autoimmune inflammation associated with amyotrophic lateral sclerosis (ALS) using two drugs, one of them already approved for multiple sclerosis, could be a promising approach for treatment. ALS, also known as Lou Gehrig's disease, is a progressive neurodegenerative disease that affects the nerve cells in the brain and spinal cord. It leads to the gradual loss of muscle control, eventually resulting in paralysis and difficulty with speech, swallowing, and breathing. The exact cause of ALS is not fully understood, and currently, there is no cure ...

Taylor & Francis has taken a significant step in reducing unnecessary plastic use with the introduction of paperwrap for journal print copies mailed in the UK. Paperwrap, a relatively new packaging technology, has become more common in recent years, but is typically most suited to publications with very high print runs. Taylor & Francis’ Global Supplier Team spent several months investigating how it might be applied to journal print runs, which included rolling out live trial mailings to colleagues around the world to test how the journals could be packaged, and whether there was any impact on the speed ...

A new talking therapy for depression has shown encouraging early signs of being more effective and cheaper to deliver than the current best practice of Cognitive Behavioural Therapy (CBT).  A pilot trial from the University of Exeter, funded by the National Institute of Health and Care Research (NIHR) and published in Lancet EClinical Medicine, has found Augmented Depression Therapy (ADepT) could be a significant advance in depression care.   A core feature of depression is anhedonia (reduced ...

A team of scientists led by CABI have conducted a new study which shows that three ways to fight the invasive Prosopis juliflora tree in Ethiopia, Kenya and Tanzania all proved very effective in almost all cases. The three-year research, published in the journal CABI Agriculture and Bioscience, revealed that cut stump and basal bark herbicide application and manual uprooting were highly effective, killing the trees in between 85-100% of cases. In addition, three incremental restoration interventions were tested ...

Laptops and schoolwork on kitchen tables, a deserted playground, face masks on a washing line, an empty church, a walk in the woods. As the UK Covid inquiry continues for a fifth week, researchers at the University of East Anglia have created a unique snapshot of lockdown life. When the pandemic first hit, the team embarked on a project to track the physical and mental health of the nation. More than a thousand participants signed up and up and they were followed every day for three months in the first study of its kind. As well as keeping daily lifestyle diaries about their physical activity, diet and mood, ...

Heliconius butterflies’ brains grew as they adopted a novel foraging behaviour, scientists at the University of Bristol have found. A region of their brain, known as the mushroom body due to its shape, are two to four times larger than those of their close relatives. The findings, published today in Nature Communications, suggest that the structure and function of the nervous system are closely linked to an organism's ecological niche and behaviour. Dr Stephen Montgomery of Bristol’s School of Biological Sciences explained: “Heliconius are the only butterflies known to collect and digest pollen, which gives them an adult source ...

New Haven, Conn. — While pembrolizumab is an approved treatment for patients with stage III non-small cell lung cancer (NSCLC), only some patients respond to this therapy. Treatment failure, researchers say, is often caused by differences in the tumor microenvironment. An ongoing phase II study (KEYNOTE-495/KeyImPaCT) led by a researcher at Yale Cancer Center reveals that combining pembrolizumab with other treatments reduced the size of target tumors, resulting in a higher response rate for patients with advanced NSCLC. The new research was published July 10 in Nature Medicine. “We are excited to share these new ...
