New model explains what we see when a massive black hole devours a star

A star that wanders too close to the supermassive black hole in the center of its galaxy will be torn apart by the black hole's gravity in a violent cataclysm called a tidal disruption event (TDE), producing a bright flare of radiation. A new study led by theoretical astrophysicists at the University of Copenhagen's Niels Bohr Institute and UC Santa Cruz provides a unified model that explains recent observations of these extreme events.

The case of the relativistic particles solved with NASA missions

Encircling Earth are two enormous rings—called the Van Allen radiation belts—of highly energized ions and electrons. Various processes can accelerate these particles to relativistic speeds, which endanger spacecraft unlucky enough to enter these giant bands of damaging radiation. Scientists had previously identified certain factors that might cause particles in the belts to become highly energized, but they had not known which cause dominates.

New federal policy would hike student spacecraft costs, threatening technology education

There are only a handful of astronauts, but every year thousands of high school and college students get to visit space vicariously, by launching their own satellites. Students design, build and test each one, and then work with space industry professionals to get them loaded on rockets and launched into orbit. But this opportunity – available to students and educators for more than 30 years – may not continue much longer, as the Federal Communications Commission considers hiking communications licensing fees beyond the reach of most students and schools.

Two teams independently come up with a way to avert CRS in CAR T-cell therapies

Two teams of researchers, one working in the U.S., the other in Italy, have come up with new ways to avert cytokine release syndrome (CRS) in leukemia patients who undergo CAR T-cell therapies. In the first, the researchers working at the Sloan Kettering Cancer Center in New York developed a mouse model to replicate the conditions under which CRS develops. They were able to isolate a key molecule involved in the syndrome and then found a drug that blocks it. The second team developed a different mouse model and found the same molecule involved. But instead of blocking it, they genetically modified the T-cells to prevent CRS from arising in the first place. Both have published their results in the journal Nature Medicine. Cliona Rooney and Tim Sauer with Baylor College offer a News & Views piece on the work done by the two teams in the same journal issue.

A key switch in biological clocks

Just as we abide by an external time schedule to eat, sleep, and go to work, our body is similarly dictated by internal clocks. Known as circadian rhythms, these daily cycles keep us on a regular 24-hour day and are involved in numerous aspects of our well-being. When these biological clocks fail to work as they should, our bodies are out of phase with the outside world and this leads to many problems, not only sleep disorders but obesity, cancer and mental health issues as well.

We could reverse aging by removing wrinkles inside our cells, study suggests

Single injection alleviates chemotherapy pain for months in mice

Researchers at University of California San Diego School of Medicine have found a new way to block a root cause of pain. The key is a naturally occurring protein called apolipoprotein A-I binding protein (AIBP). AIBP binds to toll-like receptor 4 (TLR4), a protein that sits on the surface of cells like an antenna, searching for signs of infection or tissue damage. The researchers found that treating mice with a single spinal injection of AIBP—and thus switching TLR4 "off"—prevented and reversed inflammation and cellular events associated with pain processing.

Brain scientists identify 'cross talk' between neurons that control touch in mice

Scientists report they have uncovered a previously overlooked connection between neurons in two distinct areas of the mammalian brain. The neurons, they say, control the sense of touch, and their experiments in mice offer insights into mapping brain circuitry that is responsible for normal and abnormal perception and movements linked to touch.

Impaired energy production may explain why brain is susceptible to age-related diseases

Defective energy production in old neurons might explain why our brains are so prone to age-related diseases. Salk researchers used a new method to discover that cells from older individuals had impaired mitochondria—the power stations of cells—and reduced energy production. A better understanding of the effects of aging on mitochondria could reveal more about the link between mitochondrial dysfunction and age-related brain diseases, such as Alzheimer's and Parkinson's. The work appeared in Cell Reports on May 29, 2018.

Study demonstrates link between social stress and shortened lifespan in mice

A new study from University of Minnesota Medical School researchers has demonstrated that psychosocial stress can shorten the lifespan in mice.

Scientists show how brain circuit generates anxiety

Neuroscientists at Cold Spring Harbor Laboratory (CSHL) have identified a neural circuit in the amygdala, the brain's seat of emotion processing, that gives rise to anxiety. Their insight has revealed the critical role of a molecule called dynorphin, which could serve as a target for treatment of anxiety-related disorders including post-traumatic stress disorder (PTSD).

Early-life seizures prematurely wake up brain networks tied to autism

Early-life seizures prematurely switch on key synapses in the brain that may contribute to further neurodevelopmental delay in children with autism and other intellectual disabilities, suggests a new study from researchers at Penn Medicine published online in Cell Reports. Importantly, the study shows that an existing targeted therapy may keep those synapses "silent" after seizures to allow the brain to develop normally during a critical time in a person's life. "Silent" synapses become active with experience, and removal of the reservoir of these synapses due to seizures results in a decreased capacity to engage these synapses in later learning.

Researchers magnify the brain in motion with every heartbeat

Olfactory receptor as therapeutic target in bladder cancer

Researchers from Bochum have detected an olfactory receptor in the human bladder that might prove useful for bladder cancer therapy and diagnosis. Using cell culture studies, the team headed by Prof Dr Dr Dr habil Hanns Hatt and Dr Lea Weber demonstrated that the receptor occurs more frequently in bladder cancer tissue than in healthy bladder tissue. Accordingly, significant higher amounts of the receptor could be found in the urine samples of patients. The team from the Department for Cellphysiology at Ruhr-Universität Bochum, together with colleagues from the Augusta Hospital in Bochum and the University Hospital in Düsseldorf, describes the results in the journal Frontiers in Physiology (May 16, 2018). The researchers, moreover, explain why the olfactory receptor might be a suitable therapeutic target in cancerous and other diseases of the urinary bladder.

Trial shows AZEDRA can be effective, safe for treatment of rare neuroendocrine tumors

A radiotherapy drug that treats the rare neuroendocrine cancers pheochromocytoma and paraganglioma can be both effective and safe for patients, according to the findings of a multi-center trial led by researchers in the Abramson Cancer Center of the University of Pennsylvania. The study showed AZEDRA (ultratrace iobenguane I131) led to a significant reduction in the cardiovascular side effects that are associated with these cancers while also stopping tumor growth. The drug is designed to treat malignant, recurrent, or unresectable forms of the cancers—cases for which there are currently no approved non-surgical treatments. Progenics Pharmaceuticals, which manufactures AZEDRA, recently submitted the findings of this trial as part of an application for approval to the U.S. Food and Drug Administration. The study's principal investigator Daniel A. Pryma, MD, an associate professor of Radiology and Radiation Oncology, and Chief of Nuclear Medicine and Clinical Molecular Imaging at Penn's Perelman School of Medicine, will present the results at the American Society of Clinical Oncology 2018 Annual Meeting in Chicago as an oral abstract (Abstract #4005).

A photosynthetic engine for artificial cells

In the quest to build an artificial cell, there are two approaches: The first, reengineers the genomic software of a living cell. The second, focuses on cellular hardware, building simple, cell-like structures from the ground up that mimic the function of living cells. One of the biggest challenges in this second approach is mimicking the intricate chemical and biological reactions required for cells to perform complex behaviors.

Wars and clan structure may explain a strange biological event 7,000 years ago

Starting about 7,000 years ago, something weird seems to have happened to men: Over the next two millennia, recent studies suggest, their genetic diversity —specifically, the diversity of their Y chromosomes—collapsed. So extreme was that collapse that it was as if there was only one man left to mate for every 17 women.

Could we work together with our bacteria to stop infection?

The benefits of antibiotics to both human and animal health are undisputed. However, as microbes have become increasingly resistant to antimicrobials and other drugs, scientists have become interested in new solutions to the growing superbug crisis, including the use of defensive microbes and faecal transplants. In new research, Oxford University scientists have developed a lab-based approach, creating positive co-dependent relationships between hosts and bacteria, termed 'mutualisms', quickly. These lab-developed bacterial relationships demonstrate how microbes can work with their hosts to prevent infection.

Climate change forced zombie ant fungi to adapt

Zombie ants clamp on to aerial vegetation and hang for months spewing the spores of their parasitic fungi, but researchers noticed that they do not always clamp on to the same part of the plant. Now the researchers know that the choice of leaves or twigs is related to climate and that climate change forced the fungi to adapt to local conditions.

Troika of proteins controls leaf old age onset

Researchers at the Center for Plant Aging Research, within the Institute for Basic Science (IBS), have discovered that a three protein hub – dubbed NAC troika—controls the onset of leaf old age. Their systematic study, published on Proceedings of the National Academy of Sciences of the United States of America (PNAS), describes protein networks that change during the plant lifespan and play a role in aging.

New tool for female reproductive genetics

The fruit fly Drosophila melanogaster is a powerful model organism for studying animal and human development and disease. It is low cost, generates rapidly, and there are many tools to genetically modify its cells. One tool is called the Gal4/UAS two-component activation system. It is a biochemical method used to study the process of turning a gene on (gene expression) and gene function. Although it has been a mainstay of Drosophila genetics for twenty-five years, it only functions effectively in non-reproductive cells, not in egg-producing cells. It has not been known why. Now, Carnegie's Steven DeLuca and Allan Spradling have discovered why and the have developed a new tool that can work in both cell types. The research is published in the June 2018 Genetics.

It takes a village—How researchers built their own microscope to decipher 'superbugs'

A hand-made super-microscope—capable of seeing the actual building blocks of a bacterial cell wall—has helped Monash researchers decipher how bacteria are able to literally build a wall against the immune system, leading to often deadly disease.

Researchers identify how eye loss occurs in blind cavefish

Loss of eye tissue in blind cavefish (Astyanax mexicanus), which occurs within a few days of their development, happens through epigenetic silencing of eye-related genes, according to a study led by the National Institutes of Health. Epigenetic regulation is a process where genes are turned off or on, typically in a reversible or temporary manner. This mechanism differs from genetic mutations, which are permanent changes in the DNA code. The study appears in Nature Ecology & Evolution.

Folkloric and a national symbol: saving the Balkan Lynx

In Albania, legend has it that staring into the almond-shaped eyes of the Balkan Lynx renders you blind.

Scientists develop improved model for study of Zika virus

An international research team has developed a new animal model used to study the pathogenesis of the Zika virus. Scientists were able to induce the disease in mice in a way that is similar to human pathology. The new model reflects the most dangerous manifestation of the Zika virus: infection of the fetus from a pregnant woman, which leads to developmental problems. This was achieved due to a new, more pathogenic virus strain, as well as a specially bred group of mice with a human-like immune response. The new model paves the way for more detailed study of the Zika virus, which should result in a more effective fight against it. The research is published in Cell Host & Microbe.

Hold your horses – feral horse fertility control isn't that easy

A proposed Kosciuszko Wild Horse Heritage Bill that rules out shooting horses is based on a flawed understanding of fertility control. Unfortunately, by ignoring scientific evidence and expert advice horses will be condemned to slow starvation.

The shape of the DNA helix proves to be as important as its sequence

The mechanism of DNA binding of the well-studied protein Polycomb, which is vital for cell division and embryogenesis, has finally been deciphered. A remarkable discovery, as it proves that the shape of DNA is at least as important for where the protein binds in the DNA as the DNA sequence. The role of the shape of DNA had not been demonstrated so clearly. Researchers at Radboud University will publish their findings on May 28th in the scientific journal Nature Genetics.

Viruses can cause global pandemics, but where did the first virus come from?

Viruses such as Ebola, influenza and Zika make headlines. They grab our attention with their potential to cause widespread disease and death.

Why do trees sleep badly?

You may think that trees and other plants are stationary and passive organisms that just stand around all day. So long as they get sufficient sun and water, everything is fine.

Can this bird adapt to a warmer climate? Read the genes to find out

Many animals have adaptations that help them cope with specific environments or lifestyles. Antarctic fish produce antifreeze proteins that prevent their blood from freezing in subzero temperatures. Some desert rodents survive without ever drinking a single drop of water. Humans living at high altitudes have special adaptations to cope with the low oxygen concentrations.

France vows to outlaw glyphosate weedkillers within 3 years

The French government reiterated Tuesday a campaign pledge by President Emmanuel Macron to ban glyphosate-based herbicides by 2021, after senators refused to enshrine the pledge into law.

Group making digital tool for documenting life on Earth adopts new organizational model

For more than 20 years, scientists managing biological research collections around the world have used open-source Specify software for data entry, managing museum curation, linking images and documents to specimens, and for sharing species information for education and research. Recently, the project has added options for mobile and cloud-computing technology.

Conservation groups' pact will help save Atlantic salmon

Two conservation groups said Tuesday a deal has been struck with commercial fishermen in Greenland and the Faroe Islands that will help thousands of vulnerable Atlantic salmon return to rivers in the United States, Canada and Europe.

Postbiotics and smart toilets—new era of harnessing our microbial chemicals to keep us slim and healthy

Ever since Alexander Fleming discovered penicillin growing naturally on a petri dish, we have been aware of the power of chemicals produced by microbes. But we have only recently realised their vast potential.

The last laugh – How long before the helmeted hornbill falls silent?

I'll never forget the first time I heard the maniacal cackle of a helmeted hornbill. I was standing beneath a massive fruiting fig tree in the middle of the Brunei rainforest – not exactly the heart of Borneo, but it was certainly wild enough for me – and craning my neck to catch a glimpse of the gibbons in the canopy. The ripening fruit was a magnet for all manner of other wildlife too, from wild pigs, diminutive mouse deer and tufted jungle king butterflies on the forest floor to pig-tailed macaques, barbets and, yes, hornbills in the treetops.

We are still evolving

From the colour of our eyes to the size of our brain, humans have been adapting to their environment, acquiring new abilities and losing others. We take a look at how evolution is still shaping us.
