Astronomers catch wind rushing out of galaxy

Exploring the influence of galactic winds from a distant galaxy called Makani, UC San Diego's Alison Coil, Rhodes College's David Rupke and a group of collaborators from around the world made a novel discovery. Published in Nature, their study's findings provide direct evidence for the first time of the role of galactic winds—ejections of gas from galaxies—in creating the circumgalactic medium (CGM). It exists in the regions around galaxies, and it plays an active role in their cosmic evolution. The unique composition of Makani—meaning wind in Hawaiian—uniquely lent itself to the breakthrough findings.

Technology news

Modeling and simulating complex dynamic musculoskeletal architectures

Life scientists and bioengineers study natural systems and organisms to understand their biophysical mechanisms, in order to drive biomimetic engineering applications in the lab. In a recent report on Nature Communications, Xiaotian Zhang and colleagues in the Departments of Mechanical Engineering and Supercomputing Applications in the U.S. presented a numerical approach to simulate musculoskeletal architectures. The method relied on the assembly of heterogenous active and passive Cosserat rods (a deformable-directed rod based curve) into dynamic structures to model bones, tendons, ligaments, fibers and muscle connectivity. They demonstrated applications of the technique by solving a range of problems in biological and soft robotic scenarios across many environments and scales. The team engineered bio-hybrid robots at the millimeter-scale and reconstructed complex musculoskeletal systems. The method is versatile and offers a framework to assist forward and reverse bioengineering designs for fundamental discoveries on the functions of living organisms.

Project will explore game play's potential to reduce mental distress

Shedding new light on the charging of lithium-ion batteries

Researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory have reported a new mechanism to speed up the charging of lithium-ion batteries for electric vehicles. Simply exposing the cathode to a beam of concentrated light—for example, the white light from a xenon lamp—lowers the battery charging time by a remarkable factor of two or more. If commercialized, such technology could be a game changer for electric vehicles.

New technique lets researchers map strain in next-gen solar cells

People can be good at hiding strain, and we're not alone. Solar cells have the same talent. For a solar cell, physical strain within its microscopic crystalline structure can interrupt its core function—converting sunlight into electricity—by essentially "losing" energy as heat. For an emerging type of solar cell, known as lead halide perovskites, reducing and taming this loss is key to improving efficiency and putting the perovskites on par with today's silicon solar cells.

Movement and flow: Simulating complexity of fluids and strands in the virtual world

Simulating the physics behind the movement of liquids and how fluids—thick or thin—interact with other objects is a key problem in visual effects. Bringing to life such scenarios as a brush stirring and spreading oil paint onto a canvas or spaghetti tossed in pasta sauce involves sophisticated computational modeling. These types of scenarios, in particular, are difficult to simulate due to the complex rheology of liquid—how its shape changes and transforms with movement—and the intricate interactions between the liquid and the strands.

Research reveals how malaria parasite plans ahead, preparing blueprint to strike in humans

Within seconds after an infected mosquito bites, the malaria parasite navigates the host skin and blood vessels to invade the liver, where it will stay embedded until thousands of infected cells burst into the bloodstream, launching malaria's deadly blood-stage infection.

Blood test can predict prognosis in deadly brain cancer

A blood test that measures the amount of cell-free DNA (cfDNA) in the bloodstream—called a liquid biopsy—correlates with how patients will progress after they are diagnosed with glioblastoma (GBM), the deadliest and most common primary brain tumor in adults. In a new study, researchers from the Abramson Cancer Center of the University of Pennsylvania are the first to show that patients with a higher concentration of cfDNA—circulating DNA that cancer and other cells shed into the blood—have a shorter progression-free survival than patients with less cfDNA, and that cfDNA spikes in patients either at the time of or just before their disease progresses. The team also compared genetic sequencing of solid tissue biopsies in GBM side-by-side with the liquid biopsies and found that while both biopsies detected genetic mutations in more than half of patients, none of those mutations overlapped, meaning liquid biopsy may provide complementary information about the molecular or genetic makeup of each tumor. Clinical Cancer Research, a journal of the American Association for Cancer Research, published the findings today.

Managers who have received training in mental health issues, and whose workplaces run general information campaigns on mental health, are significantly more likely to work preventively in this area vis-à-vis their subordinates, a study shows. This applies irrespective of organization size and managers' own experiences of mental ill-health.

Survey suggests mentorship in medical school is vital to future of hematology

A survey of U.S. hematology-oncology fellows suggests medical school plays an important role in shaping their interest in pursuing careers in hematology, particularly when students are exposed to hematology and oncology as part of core clerkships in internal medicine and pediatrics. The study, funded by the American Society of Hematology (ASH) and published today in Blood Advances, also indicates that having a hematologist as a mentor during medical education and training is associated with an increased likelihood of fellows specializing in hematology when they complete their hematology-oncology fellowship.

Heavy smoking causes faces to look older

"Smoker's Face," a condition where smokers look older than they are, is just one of many negative effects caused by heavy tobacco usage. Louise Millard of the University of Bristol and colleagues report these findings in a new study published 31st October in PLOS Genetics.

The study, which was conducted by investigators at Massachusetts General Hospital (MGH) in collaboration with scientists from Changchun Institute of Applied Chemistry of Chinese Academy of Sciences and Leibniz Institute for Interactive Materials in China and Germany, is published as a very important paper (VIP) in Angewandte Chemie International Edition.

Five-year breast cancer survival rates at a safety net hospital rival national averages

Patients treated for breast cancer at a Miami safety net hospital achieved similar five-year survival outcomes to national averages, despite having a patient population that was largely poor, uninsured, and diagnosed with more advanced disease, according to findings from a pair of studies presented at the American College of Surgeons Clinical Congress 2019.

Gallbladder removal linked to better outcomes when performed soon after hospital admission

Delaying a needed gallbladder removal operation (known as a cholecystectomy) for an inflamed gallbladder (called acute cholecystitis) for more than 72 hours after hospital admission may not be the safest approach for patients. Surgeons report a 72-hour delay increases the odds of complications and 30-day readmissions, lengthens hospital stays, and may make patients likelier to need open operations, compared with patients who have the operation performed within 24 hours of admission, according to research findings presented at the American College of Surgeons Clinical Congress 2019.

Surgeons report that 12-hour shifts improve patient outcomes, lower costs

For covering emergency and urgent operations, hospitals have traditionally assigned general surgeons to 24-hour on-call schedules, which often puts them in a situation where they need to operate and make complex medical decisions after being on duty for 18 or 20 hours or more. However, Texas Tech University Health Sciences Center, Lubbock, Tex., has used a model to cap surgeon shifts at 12 hours for covering surgical emergencies, and a study has shown that it led to shorter hospital stays and lower overall costs for patients with acute appendicitis, according to findings presented at the American College of Surgeons Clinical Congress 2019.

Study reveals surprising amount of gene flow among butterfly species

An international team of researchers analyzed the genomes of 20 butterfly species and discovered a surprisingly high amount of gene flow among them - even between species that are distantly related. The findings, published in the journal Science, challenge conventional views about species and point to hybridization as a key process in the emergence of biological diversity.

Unlocking the black box of embryonic development

Little is known about the molecular and cellular events that occur during early embryonic development in primate species. Now, an internationally renowned team of scientists in China and the United States has created a method to allow primate embryos to grow in the laboratory longer than ever before, enabling the researchers to obtain molecular details of key developmental processes for the first time. This research, while done in nonhuman primate cells, can have direct implications for early human development.

Insect decline more extensive than suspected

Compared to a decade ago, today the number of insect species in many areas has decreased by about one-third. This is the result of a survey of an international research team led by scientists from the Technical University of Munich (TUM). The loss of species mainly affects grasslands in the vicinity of intensively farmed land—but also applies to forests and protected areas.

First South American insect that emits blue light is discovered

Brazilian researchers have discovered a new species of fungus gnat (Keroplatidae) whose larvae emit blue light. The small fly inhabits an Atlantic Rainforest reserve in São Paulo State. This is the first record of a blue bioluminescent species in the Neotropics. Many bioluminescent insects and fungi have been studied in the region, but all emit green, yellow or red light. The new species has been named Neoceroplatus betaryiensis and is described in an article in Scientific Reports.

Vampire bats give a little help to their 'friends'

Vampire bats could be said to be sort of like people—not because of their blood-sucking ways, but because they help their neighbors in need even if it's of no obvious benefit to them.

Disease-causing protein in cystic fibrosis has ancient roots in sea lamprey

The oldest known ortholog of the ion channel that is defective in patients with cystic fibrosis arose approximately 450 million years ago in the sea lamprey, researchers report October 31st in the journal Developmental Cell. Many differences between lamprey and jawed vertebrate orthologs of this protein, called the cystic fibrosis transmembrane conductance regulator (CFTR), are vestiges of the evolutionary transition from a transporter to a specialized chloride and bicarbonate channel. Other differences likely reflect later adaptation of the sea lamprey to its specific environment.

Fish simulations provide new insights into energy costs of swimming

A new computational analysis suggests that maximizing swimming speeds while minimizing energy costs depends on an optimal balance between a fish's muscle dynamics and the way its size, shape, and swimming motion affect its movement through water. Grgur Tokic and Dick Yue of the Massachusetts Institute of Technology present these findings in PLOS Computational Biology.

A protein that pulls the brake on nerve growth

During embryonic development, nerve cells form long, thin extensions that wire up the complex network of the brain. Scientists from the German Center for Neurodegenerative Diseases (DZNE) in Bonn have now identified a protein that regulates the growth of these extensions by pulling a brake. In the long run, their findings could help to develop new approaches for the treatment of spinal cord injuries. The study is published in the journal Current Biology.

Dental stem cells can generate milk-producing cells

Stem cells of the teeth can contribute to the regeneration of non-dental organs, namely mammary glands.

Researchers describe how Vitamin E works in plants under extreme conditions

Vitamin E is a strong antioxidant that could act as a sentinel in plants, sending molecular signs from chloroplast, a cell organelle, to the nucleus under extreme environmental conditions. This is among the conclusions of an article published in Trends in Plant Science by Sergi Munné-Bosch and Paula Muñoz from the Faculty of Biology of the University of Barcelona (UB).

Calculating 'run and tumble' behavior of bacteria in groundwater

Bacteria in groundwater move in surprising ways. They can passively ride flowing groundwater, or they can actively move on their own in what scientists call "run and tumble" behavior. However, most numerical models of bacterial transport in groundwater stumble when it comes to calculating how bacteria move. As a first step in improving these models, scientists studied the movements of two kinds of microorganisms. They then factored those characteristics into a simple micro-scale transport model that more accurately predicted changes underground.

'Fungal feature tracker' could accelerate mycology research
