Rare glimpse of a black hole's magnetic field could help us to understand how it feeds

Encountering a black hole would be a frightening prospect for our planet. We know that these cosmic monsters ferociously devour any object that strays too close to their "event horizon" – the last chance of escape. But even though black holes drive some of the most energetic phenomena in the universe, the physics of their behaviour, including how they feed, remains hotly debated.

Mars atmosphere well protected from the solar wind

Despite the absence of a global Earth-like magnetic dipole, the Martian atmosphere is well protected from the effects of the solar wind on ion escape from the planet. New research shows this using measurements from the Swedish particle instrument ASPERA-3 on the Mars Express spacecraft. The results have recently been presented in a doctoral thesis by Robin Ramstad, Swedish Institute of Space Physics and UmeƄ University, Sweden.

Dusty protoplanetary disks

Planetary systems form out of disks of gas and dust around young stars. How the formation proceeds, however, is complex and poorly understood. Many physical processes are involved including accretion onto the star, photoevaporation of material of the disk, interactions of the disk with planetary embryos, growth of the dust grains, settling of the dust to the midplane of the disk, and more. To unravel these various factors, observations of protoplanetary disks at multiple wavelengths are used; the submillimeter wavelength range in particular offers a way to peer through most of the disk to estimate dust masses directly.

Insights on fast cockroaches can help teach robots to walk

Using the example of cockroaches, the Cologne-based zoologist Dr Tom Weihmann and his team were able to show that quickly running insects change their gait at mid-speed. This behaviour has previously only been observed in fast mammals. This change in gait is similar to the way horses change from trop to gallop. The results of the study have now been published in the journal Frontiers in Zoology.

Will artificial intelligence become conscious?

Forget about today's modest incremental advances in artificial intelligence, such as the increasing abilities of cars to drive themselves. Waiting in the wings might be a groundbreaking development: a machine that is aware of itself and its surroundings, and that could take in and process massive amounts of data in real time. It could be sent on dangerous missions, into space or combat. In addition to driving people around, it might be able to cook, clean, do laundry – and even keep humans company when other people aren't nearby.

Unique pattern of brain inflammation may explain neurocognitive impairment in HIV patients on antiretroviral drugs

Although combination antiretroviral therapy (cART) has improved survival of patients infected with HIV and has reduced the incidence of severe neurologic complications, almost half of cART-treated HIV patients experience some degree of neurocognitive impairment (neuroHIV). To search for underlying pathology, scientists analyzed the brains of monkeys infected with simian immunodeficiency virus (SIV) then treated with cART. As reported in a new study in The American Journal of Pathology, the majority of the SIV-infected macaque brains showed signs of unusual lymphocyte-dominant inflammation, suggesting that persistent neuroinflammation may underlie cognitive problems in cART-treated HIV patients.

Protamine neutralizes CSPG-mediated inhibition of oligodendrocyte differentiation

Remyelination is a critical repair process in demyelinating diseases such as multiple sclerosis (MS). Chondroitin sulfate proteoglycans (CSPGs), a family of large molecules consisting of a core protein and glycosaminoglycans comsposed of chains of alternating sugars, are enriched in glial scars. In MS lesions, CSPGs accumulate as constituents of demyelinating plaques, which inhibit the migration and differentiation of oligodendrocyte precursor cells and remyelination.

Long-term prevention of organ rejection

The Konstanz immunologist Professor Marcus Groettrup and his team have developed a procedure for preventing organ rejection in rats after renal transplantation, and for suppressing the creation of antibodies in the recipients' immune systems. Immunoproteasome inhibition, which suppresses the production of antibodies, is crucial to this process. The research results were published in Kidney International. The title of the original publication is "Immunoproteasome inhibition prevents chronic antibody-mediated allograft rejection in renal transplantation."

How developing visual system axons stay in the correct layer

Scientists at Tokyo Tech have made an important discovery concerning the development of layer-specific axonal connections in the developing visual system of Drosophila flies. This discovery provides valuable insights into how neurons in the developing brain are wired. The molecular mechanisms we found can serve as a universal principle for wiring axons also in higher animals. We assume our findings help stabilize the regenerating axons to the desired depth in the brain layers, in the case such as neuronal transplantation after injury.

Deep insight into the heart

By no means are only elderly people at risk from heart diseases. Physically active individuals can also be affected, for example if a seemingly harmless flu bug spreads to the heart muscle. Should this remain undetected and if, for example, a builder continues with his strenuous job or an athlete carries on training, this can lead to chronic inflammation and in the worst case even to sudden death. The latest issue of the "Forschung Frankfurt" journal describes how modern non-invasive examinations using state-of-the-art imaging technology can reduce such risks.

Including diagnosis related costs, 3-D mammography costs less than digital mammography

Although digital breast tomosynthesis (DBT), or 3-D mammography, costs more than a digital mammography (DM) screening, it actually may help rein in cancer screening costs, according to preliminary findings (PD7-05) presented by researchers from the Perelman School of Medicine at the University of Pennsylvania during the 2017 San Antonio Breast Cancer Symposium. The group analyzed 46,483 screening episodes - a single screening mammogram and all subsequent breast diagnosis related costs for the following year - in two hospitals within the University of Pennsylvania Health System in 2012 and 2013.

Large proportion of patients experiencing acute exacerbations of COPD are skipping out on pulmonary rehabilitation

Acute exacerbations of COPD (AECOPD) can negatively impact a patient's health-related quality of life, lead to a decline in pulmonary function, and can also cause an increased use of health care resources. On average, patients with COPD have one to three treated exacerbations per year, and up to 25 percent of patients with COPD who are hospitalized for an exacerbation die within a year. In the past, systematic reviews have shown that pulmonary rehabilitation (PR) can reduce hospital admissions, but referral rates lacked consistency. Researchers from Imperial College London set out to determine the effect of PR on COPD exacerbation rates.

New strategy could enable existing drugs to kill bacteria that cause chronic infections

MIT researchers have discovered a way to make bacteria more vulnerable to a class of antibiotics known as quinolones, which include ciprofloxacin and are often used to treat infections such as Escherichia coli and Staphylococcus aureus.

The future of crop engineering 

Photosynthesis is the process underlying all plant growth. Scientists aim to boost photosynthesis to meet the increasing global demand for food by engineering its key enzyme Rubisco. Now, researchers at the Max Planck Institute of Biochemistry have succeeded in producing functional plant Rubisco in a bacterium. This allows genetic engineering of the enzyme. The study could one day lead to better crop yields and plant varieties with increased water-use efficiencies or enhanced temperature resistance. The results were published in Science.

Rethinking transcription factors and gene expression

Transcription—the reading of a segment of DNA into an RNA template for protein synthesis—is fundamental for nearly all cellular processes, including growth, responding to stimuli, and reproduction. Now, Whitehead Institute researchers have upended our understanding of how transcription is controlled and the role of transcription factors in the process.

Can data save dolphins? How scientists are using NASA data to study link between solar storms and animal beachings

The age-old mystery of why otherwise healthy dolphins, whales and porpoises get stranded along coasts worldwide deepens: After a collaboration between NASA scientists and marine biologists, new research suggests space weather is not the primary cause of animal beachings—but the research continues. The collaboration is now seeking others to join their search for the factors that send ocean mammals off course, in the hopes of perhaps one day predicting strandings before they happen.

Many more bacteria have electrically conducting filaments

Microbiologists led by Derek Lovley at the University of Massachusetts Amherst, who is internationally known for having discovered electrically conducting microfilaments or "nanowires" in the bacterium Geobacter, announce in a new paper this month that they have discovered the unexpected structures in many other species, greatly broadening the research field on electrically conducting filaments. Details appear online in the International Society of Microbial Ecology Journal.

Like seasoned holiday enthusiasts, majoid crabs decorate their shells

'Tis the holiday season and it seems homes are festively trimmed at every turn. Ornaments of all shapes and sizes embellish everything from trees to windows and yards.

The unique pentraxin-carbonic anhydrase protein regulates the ability of fish to swim

A study carried out at the University of Tampere has shown that carbonic anhydrase VI (CA VI) is present in some species as a combination of two proteins. According to current data, this "fusion protein," called pentraxin-carbonic anhydrase, has disappeared from the genome of almost all mammals through evolution.

How toxoplasmosis exploits immune cells to reach the brain

The infection toxoplasmosis is caused by the parasite Toxoplasma gondii and is widespread. It's estimated that 30 to 50 percent of the global human population are carriers. Cats are the parasites' main host, but the infection is also spread among other animals, including humans. A series of studies has previously shown that the parasite affects the brains of infected rats so that they lose fear of cats and even become attracted to cats' scent, making them an easy prey. The parasite spreads by ensuring that the rat is eaten by a cat. Toxoplasmosis is life-threatening to people with impaired immune systems and to unborn foetuses, but causes only mild symptoms in healthy individuals. However, there are studies showing that mental illnesses such as schizophrenia, depression and anxiety disorder are more common in people who are carriers of Toxoplasma gondii. There are also studies indicating that the parasite may affect aggressive or risky behaviour.

DNA has gone digital – what could possibly go wrong?

Biology is becoming increasingly digitized. Researchers like us use computers to analyze DNA, operate lab equipment and store genetic information. But new capabilities also mean new risks – and biologists remain largely unaware of the potential vulnerabilities that come with digitizing biotechnology.

Designer yeast consumes plant matter and spits out fatty alcohols for detergents and biofuels

Used in laundry detergents, medicines, and biofuels, certain alcohols known as long-chain fatty alcohols, with 12 to 18 carbon atoms in the backbone, are desirable products. These compounds can be made by a yeast called Saccharomyces cerevisiae. However, yields have remained low, slowing the adoption of microbes as producers of fatty alcohols. Through genetic engineering of S. cerevisiae, scientists improved the concentration and yield of fatty alcohol products from 2 percent to up to 20 percent of the maximum theoretical yield.

Underappreciated microbes now get credit for holding down two jobs in soil

In soil, bacteria and other microbes are well known for their ability to decompose organic materials, releasing carbon to the atmosphere. Less understood is how microbes add persistent carbon compounds to the soil. Scientists reviewed both roles via the concept of a "microbial carbon pump." The pump is proposed as a mechanism for integrating how the contrasting breakdown and synthesis activities of microbes—coupled with the "entombment" of microbial residues—influence carbon levels in the soil.

Jellyfish have superpowers – and other reasons they don't deserve their bad reputation

People rarely enjoy meeting a jellyfish. On the beach they appear limp, amorphous, and blistered in the sun. In the water it's often a brush of a tentacle on exposed skin followed by a sting. They hardly evoke the serene elegance of a turtle or the majesty of a breaching humpback whale. But despite making a poor first impression, jellyfish are among the most unusual animals on Earth and deserve a second chance to introduce themselves.

New tool could help maintain quality during cheese production

Dutch type cheeses, notably edam and gouda, are made using complex starter cultures, that have been employed for centuries. Due to changes in strain composition within a culture, the quality frequently fluctuates. A team of Norwegian investigators has developed a tool that could be used to monitor the strains within a culture with high resolution, in order to maintain cheese quality. The research is published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.

Algae and krill may be a tough sell for European consumers

People will need to be persuaded to eat new types of seafood if we are to extract more food from the oceans and feed growing human populations, according to fishing industry experts.

Study shows differences in energy digestibility between sows and gilts

Gestating sows digest energy in diets more efficiently than growing gilts. A recent study from the University of Illinois is shedding light on some of the reasons why.

Militias, poachers wreak havoc on central Africa's wildlife: monitor

Sudan's Janjaweed, Uganda's Lord's Resistance Army and other notorious militias are wreaking havoc on wildlife in central Africa, poaching and trafficking elephants, hippopotamuses, buffaloes and other animals, a monitor said Friday.

Bird flu: Dutch farmers ordered to keep poultry indoors

The Dutch government has ordered the country's farmers to keep all poultry indoors after bird flu was discovered at a duck farm.

25 species revealed for 25 Genomes Project

To commemorate the Wellcome Trust Sanger Institute turning 25 in 2018, the Institute and its collaborators are sequencing 25 new genomes of species in the UK. The final five species have now been chosen by thousands of school children and members of the public around the globe, who participated in the 25 Genomes Project online vote.
