New clues about how ancient galaxies lit up the universe

NASA's Spitzer Space Telescope has revealed that some of the universe's earliest galaxies were brighter than expected. The excess light is a byproduct of the galaxies releasing incredibly high amounts of ionizing radiation. The finding offers clues to the cause of the Epoch of Reionization, a major cosmic event that transformed the universe from being mostly opaque to the brilliant starscape seen today.

Evolution of magnetic field in the star-forming complex G9.62+0.19 revealed by ALMA

Using the Atacama Large Millimeter Array (ALMA), European astronomers have investigated the magnetic field of the high-mass star-forming region known as G9.62+0.19. Results of these observations, presented in a paper published May 1 on arXiv.org, provide insights into the evolution of this magnetic field, which could help astronomers better understand the role of magnetic fields in the formation of massive stars.

Gravitational waves leave a detectable mark, physicists say

Gravitational waves, first detected in 2016, offer a new window on the universe, with the potential to tell us about everything from the time following the Big Bang to more recent events in galaxy centers.

Star formation burst in the Milky Way 2–3 billion years ago (Update)

A team led by researchers of the Institute of Cosmos Sciences of the University of Barcelona (ICCUB, UB-IEEC) and the Besançon Astronomical Observatory have analyzed data from the Gaia satellite and found that a heavy star formation burst occurred in the Milky Way about 3,000 million years ago. During this process, more than 50 percent of the stars that created the galactic disc may have been born. These results are derived from the combination of the distances, colors and magnitude of the stars that were measured by Gaia with models that predict their distribution in our galaxy. The study has been published in the journal Astronomy & Astrophysics.

Researchers suggest collapsar accretion disks might be source of heaviest elements

A trio of researchers at Columbia University is suggesting that collapsar accretion disks might be the major source of the heaviest elements.

Neurodevelopmental disorders may be rooted in genetics and mitochondrial deficits

Under-connectivity, or too few connections in the brain, is the underlying cause of brain disorders like autism and schizophrenia, according to a recent study from investigators at the George Washington University (GW) Institute for Neuroscience. The study, published in Neuron, provides the first evidence showing that individual nerve cells fail to make the right number of connections. The reason for this deficit is limited growth of key nerve cells in the cerebral cortex during early development, due to both genetics and mitochondrial dysfunction.

The findings suggest exciting new targets for developing precision medicine strategies in the future.

'Number sense' arises from the recognition of visible objects

Humans and animals have a "number sense," an inborn ability to register the number of objects in a scene. The neural basis of this ability is believed to be what are called the number neurons, which respond to certain numbers and have been found in both human and animal brains. Researchers have long wondered whether these number neurons are formed in the brain merely by the ability to see—and if so, how. Now, a team of researchers headed by Professor Andreas Nieder at the University of Tübingen's Institute of Neurobiology has investigated the origins of number sense using an artificial neural network. The results indicate that it is created spontaneously by the visual system, without any experience in counting. The study has just been published in the latest edition of Science Advances.

A link between mitochondrial damage and osteoporosis

Some risk factors for osteoporosis such as being older and female or having a family history of the condition cannot be avoided. But others can, like smoking cigarettes, consuming alcohol, taking certain medications, or being exposed to environmental pollutants. But until now researchers haven't gained a firm picture of how these exposures link up with bone loss.

Biomarker may help identify men with prostate cancer at greater risk of tumor metastasis

For about 90 percent of men with prostate cancer, the cancer remains localized to the primary site, resulting in a five-year survival rate of almost 100 percent. Unfortunately, the remaining 10 percent of patients develop locally invasive and metastatic disease, which increases the severity of the disease and likelihood of death and limits treatment options. A report in The American Journal of Pathology indicates that a significantly lower presence of syntaphilin (SNPH)—a mitochondrial protein—within the tumor's central core versus at the tumor's invasive outer edge, may identify patients at increased risk of metastasis. These patients may require more rigorous testing, surveillance, and treatment.

Women perceive the potential benefits of mammograms to be more important than the potential harms

In 2009, disagreement in the health community arose following a recommendation from the United States Preventive Services Task Force (USPSTF) against routine mammogram screening for women ages 40-49 who are at average risk for breast cancer. Then, in 2015, the American Cancer Society (ACS) updated its 2003 breast cancer screening guidelines, changing the recommended starting age of routine screening from 40 to 45. These new recommendations all emphasized the importance of younger women weighing the potential benefits of mammograms against the possible harms to make an informed decision about when to begin routine screenings.

Specific identification of chronic lung disease in premature babies

Infants born prematurely frequently develop a form of chronic lung disease known as Bronchopulmonary Dysplasia. Previously, this disease could only be diagnosed clinically and with a low degree of differentiation. Researchers at the Helmholtz Zentrum München and the University Hospital of the Ludwig-Maximilians University – partner in the German Center for Lung Research (DZL) – have now successfully developed a new protocol for identifying neonatal patients with the disease by the use of magnetic resonance imaging (MRI). Their findings have now been published in Thorax.

Gold makes invisible surfaces visible in CT

Today, the three-dimensional visualization and analysis of biological samples using computer tomography (CT) is a routine procedure. However, in the past, it was very difficult to visualize the fine surface details of many organisms. Scientists at the Universities of Cologne and Bonn and the Zoological Research Museum Alexander Koenig—Leibniz Institute for Animal Biodiversity in Bonn have now developed a new method to digitally capture and display even the finest surface structures. To achieve this, they coated the samples with a thin layer of gold, a technique that has previously only been used in scanning electron microscopy. Besides the implementation in biological sciences, the new method also holds promise for more practical areas of application such as material sciences or quality control in manufacturing companies. The research results have now been published in the Journal of Anatomy.

Why suburban parks offer an antidote to helicopter parenting

Patient registries could help control spread of antibiotic bacteria

A new study led by researchers at the Johns Hopkins Bloomberg School of Public Health finds that the spread of carbapenem-resistant Enterobacteriaceae (CRE)—bacteria that have high levels of resistance to most antibiotics—could be reduced if only 25 percent of the largest health care facilities in a region used a patient registry, a database that can track which patients are carrying CRE.

Anger more harmful to health of older adults than sadness

Anger may be more harmful to an older person's physical health than sadness, potentially increasing inflammation, which is associated with such chronic illnesses as heart disease, arthritis and cancer, according to new research published by the American Psychological Association.

How humans interact with the changing environment is affecting the spread of infectious disease

Some of the world's most notorious infections – including Lyme disease, rabies, and Ebola come from zoonotic diseases. These illnesses are caused by pathogens (bacteria, viruses, or other parasitic organisms) which can be passed from animals to humans. But, even though they can lead to serious health problems, there is a gap in our knowledge when it comes to these diseases. We don't yet fully understand how pathogens "shift" between different host species and cause epidemics – and research is starting to show that the changing environment could be a factor.

Numbing a body part can boost sensory powers elsewhere—here's what that tells us about the brain

When you wake up in the middle of the night in total darkness, it can feel as if you have auditory superpowers. Suddenly, you can hear floorboards creak storeys below and the softest rustle of foxes destroying the bins outside, once again. Indeed, it is common wisdom that when you lose one sense, the remaining senses heighten.

What do parents of children with cancer search for online?

When a child has cancer, what kind of information do parents seek out? Analyzing their online searches to obtain health-related information offers one window into their concerns, and provides insight into how healthcare providers may offer family education and support. Oncology researchers who investigated parents' online Google searches found that, among other things, parents frequently focus on ways to best support their child and on logistical issues, such as directions to medical centers and appropriate pharmacies.

Fooling nerve cells into acting normal

Nerve cells, or neurons—specifically the "workhorse cells" involved in walking, breathing and chewing—can adjust to changes in the body, but they never stop working unless there is an fatal injury. What exactly signals neurons to keep acting and operating normally has not been known until now. In a new study, scientists at the University of Missouri have discovered that a neuron's own electrical signal, or voltage, can indicate whether the neuron is functioning normally. If that voltage is absent, scientists say everything is "out of whack."

The little pygmy hog turns out to be a big piece in resolving the complex evolutionary puzzle of wild boar speciation. Researchers from Wageningen University & Research found the common wild boar interbred with other wild boar subspecies during their expansion from South East Asia to the Indonesian isles, Europe and North Africa, just like human ancestors 'interbred' with Neanderthals. Their findings are reported in Nature Communications.

Water flea can smell fish and dive into the dark for protection

Water fleas, or Daphnia, ensure their survival by reacting to a signal substance of their predators (fish) with flight. The zoologist Meike Anika Hahn from Professor Dr. Eric von Elert's research group at the University of Cologne's Institute of Zoology has identified this chemical messenger substance, which the fish releases into the water of lakes. When the water flea detects the substance 5α-cyprinol sulfate—a bile salt from the fish—it leaves the upper water layers and descends vertically into darker regions. The fish are unable to visually detect their prey there during daytime. This connection between the signal of the predator and the behaviour of its prey has now been published in the scientific journal eLife under the title '5α-cyprinol sulfate, a bile salt from fish, induces diel vertical migration in Daphnia."

Location is everything for plant cell differentiation

While the fate of most human cells is determined by their lineage—for example, renal stem cells go on to form the kidney while cardiac progenitor cells form the heart—plant cells are a little more flexible. Research shows that although they undergo orderly division during growth, the fate of plant cells is often determined by their location in the growing plant rather than how they started out. Intriguingly, this suggests that plant cells recognize where they are and can alter gene activity in response to their location.

Dexterous herring gulls learn new tricks to adapt their feeding habits

Observations of Herring Gulls by scientists from the University of Southampton have shown how the coastal birds have developed complicated behaviour to 'skin' sea creatures to make them safe to eat.
