Why the discovery of a bevy of quasars will boost efforts to understand galaxies' origins

Late last year, an international team including researchers from the Kavli Institute for Astronomy and Astrophysics (KIAA) at Peking University announced the discovery of more than 60 extremely distant quasars, nearly doubling the number known to science - and thus providing dozens of new opportunities to look deep into our universe's history.

NASA Mars orbiter tracks back-to-back regional storms

A regional dust storm currently swelling on Mars follows unusually closely on one that blossomed less than two weeks earlier and is now dissipating, as seen in daily global weather monitoring by NASA's Mars Reconnaissance Orbiter.

High performance of single stage sounding hybrid rockets using design informatics

Single-stage sounding rockets are used to transport scientific equipment into, or just beyond, Earth's atmosphere to measure phenomena such as aurora. Recently, scientists have begun designing rockets with hybrid engines, which work by alternating between different phases of solid fuel and liquid or gas oxidizers. Hybrid rockets are cheaper, safer and cleaner than those with conventional solid fuel engines.

Life on Earth is used to gravity – so what happens to our cells and tissues in space?

There's one force whose effects are so deeply entrenched in our everyday lives that we probably don't think much about it at all: gravity. Gravity is the force that causes attraction between masses. It's why when you drop a pen, it falls to the ground. But because gravitational force is proportional to the mass of the object, only large objects like planets create tangible attractions. This is why the study of gravity traditionally focused on massive objects like planets.

Image: Cassini reveals strange shape of Saturn's moon Pan

These raw, unprocessed images of Saturn's tiny moon, Pan, were taken on March 7, 2017, by NASA's Cassini spacecraft. The flyby had a close-approach distance of 24,572 kilometers (15,268 miles).

The future of space colonization – terraforming or space habitats?

The idea of terraforming Mars – aka "Earth's Twin" – is a fascinating idea. Between melting the polar ice caps, slowly creating an atmosphere, and then engineering the environment to have foliage, rivers, and standing bodies of water, there's enough there to inspire just about anyone! But just how long would such an endeavor take, what would it cost us, and is it really an effective use of our time and energy?

Superluminous supernovae

Supernovae, the explosive deaths of massive stars, are among the most momentous events in the cosmos because they disburse into space all of the chemical elements that were produced inside their progenitor stars, including the elements essential for making planets and life. Their bright emission also enables them to be used as probes of the very distant universe. Not least, supernovae are astrophysical laboratories for the study of very energetic phenomena. One class of supernovae consists of single stars whose mass is at least eight solar masses as they finish their lives.

NASA mission named 'Europa Clipper'

NASA's upcoming mission to investigate the habitability of Jupiter's icy moon Europa now has a formal name: Europa Clipper.

Technology news

Drone approach to survive collision: Be flexible, be rigid, be insect

Taking on a bioinspired strategy in the field of robotics is nothing new. Especially in the case of insects, researchers far and wide look to them for inspiration. Tracey Lien in Los Angeles Times said many robots have been built just to better understand insects themselves.

The prototype of a chemical computer detects a sphere

Researchers in Warsaw have developed a system that uses chemistry to make computations. After an appropriate teaching procedure, even a relatively simple chemical system can perform non-trivial operations. In their most recent computer simulations, the researchers have shown that correctly programmed chemical matrices of oscillating droplets can recognize the shape of a sphere with great accuracy.

System provides readers with detailed summaries of online discussions

From Reddit to Quora, discussion forums can be equal parts informative and daunting. We've all fallen down rabbit holes of lengthy threads that are impossible to sift through. Comments can be redundant, off-topic or even inaccurate, but all that content is ultimately still there for us to try and untangle.

Your brain is unique – here's how it could be used as the ultimate security password

Biometrics – technology that can recognise individuals based on physical and behavioural traits such as their faces, voices or fingerprints – are becoming increasingly important to combat financial fraud and security threats. This is because traditional approaches, such as those based on PIN numbers or passwords, are proving too easily compromised. For example, Barclays has introduced TouchID, whereby customers can log onto internet banking using fingerprint scanners on mobile phones.

California to give the green light to truly driverless cars

Cars with no steering wheel, no pedals and nobody at all inside could be driving themselves on California roads by the end of the year, under proposed new state rules that would give a powerful boost to the fast-developing technology.

New law will force some (but not all) organisations to reveal data breaches

We live in an era of big data stored digitally, and some of that data is about you. For example, the government keeps your social security and tax data, banks keep your financial data and your phone provider stores your metadata.

Why we should not know our own passwords

Since 2009, U.S. Customs and Border Protection agents have been allowed to search electronic devices carried by citizens or noncitizens as they cross the border into the United States from other countries. More recently, Homeland Security Secretary John Kelly suggested this digital vetting should also include harvesting social media passwords. Kelly's proposal prompted legal and technology experts to respond with an open letter expressing deep concern about any policy that demands that individuals violate the "first rule of online security": Do not share your passwords.

How can we share solutions to complex systems problems across domains and application areas?

What do power networks, transportation hubs, weather patterns, commercial organisations and swarming robots have in common?

World's first test site for autonomous vehicles opens

Norway's Trondheim Fjord will be the world's first technological playground for pilotless vehicles that move below, on and above the water's surface.

Could Bill Gates' plan to tax robots really lead to a brighter future for all?

Bill Gates has stated in an interview that robots who take human jobs should pay taxes. This has some obvious attractions. Not only, as Gates says, will we be able to spend the money to finance jobs for which humans are particularly suited, such as caring for children or the elderly, but robots are also unlikely to complain about tax levels, they don't use services financed by tax revenue such as education or the health services and they are most unlikely to salt away income and assets in a tax haven. What's not to like?

.africa joins the internet

In the beginning was .com, followed by a host of other .somethings, but on Friday, 32 years after the world's first domain name was registered, the African Union has launched .africa for the continent.

An international research collaborative has identified potential alcoholism mechanisms associated with altered dopaminergic neuron response to complex dynamics of prefrontal cortex neurones affecting dopamine release.

A sweet vaccine against pneumonia

It may not take much to vaccinate against a particularly dangerous pathogen that causes pneumonia. A molecule consisting of three adjoined sugars is sufficient to protect against infections with highly virulent and antibiotic-resistant streptococci. The trimer stimulates the immune system to form antibodies against the bacterium Streptococcus pneumoniae of serotype 8, short ST8, as researchers of the Max Planck Institute for Colloids and Interfaces in Potsdam demonstrated by in vivo tests. They illustrate how a new generation of tailor-made vaccines of can be developed.

Study suggests risky aspects of teen brains can be tamed by circumstances

An international team of researchers has found that despite having brains that make them more risk-prone, recklessness by teens is not an inevitable part of adolescence. In their paper published in the journal Developmental Science, the group describes how they surveyed teenagers from around the world to learn more about adolescent behavior and their results compared with recent findings regarding the teenage brain.

Doctors find patient brain activity continued for 10 minutes after death

A team of doctors affiliated with the University of Western Ontario in Canada has documented a case in which a terminal patient removed from life support continued to experience brain wave activity for approximately 10 minutes after they had been pronounced clinically dead.

A breath of fresh air for severe asthma research

Ten to 15 percent of people with asthma have severe asthma, a form of the disease that is not controlled by current medications. Many of these patients are prescribed increased dosages of corticosteroids, but continue to experience daily symptoms and recurrent infections, showing little improvement. The cause of severe asthma and why corticosteroids are ineffective for patients with severe asthma has been a mystery, until now. New research led by a team of investigators at Brigham and Women's Hospital points to immunological differences in responses to steroids in patients with severe asthma, suggesting why corticosteroids may paradoxically perpetuate inflammation in severe asthma. Their findings appear online this week in Science Immunology.

Why do we develop high blood pressure?

Abnormally high blood pressure, or hypertension, may be related to changes in brain activity and blood flow early in life. That's according to a study conducted on a rat model of high blood pressure, published in Experimental Physiology.

Children's daily life highly regulated, according to study

Children in Sweden and the US experience their daily life as highly structured and regulated. But while US children state that homework and long schooldays are what makes everyday life difficult, Swedish children point to the continuous nagging and stress that occur in relation to daily routines. These are some key findings of a new study from the University of Gothenburg.

How a child made scientists think of cytokines as knobs instead of switches

An unusual case of a rare anemia is opening scientists up to a new way of thinking about how to adapt and employ cytokines, messenger molecules of the blood and immune system, as tools for treatment—tools that are more analog than digital—and to illustrate the promise of precision medicine.

My doctor says there's a guideline for my treatment – but is it right for me?

Health care guidelines are produced in ever-increasing numbers. The National Guideline Clearinghouse, a U.S.-based public website compiling summaries of "clinical practice" (health care) guidelines, has over 1,000 entries and is updated weekly. The National Institute for Health and Care Excellence in the U.K. has over 180 clinical guidelines.

Kind words can prime the body's response to pain, professor says

Unless he's the doctor, there isn't much a man can do in a birthing room. He can fetch ice chips or prop pillows behind the mother's back. He can suggest some Lamaze breathing—"Hee hee hooooo"—when the contractions intensify. He can stop when she's had enough of that.

The new finding by an international collaboration of scientists adds to list of newly identified diseases called ribosomopathies.

It's not what sport kids play but how they play it that matters

Sport is massive and it's everywhere: on TV, in videogames, and on the streets. As a consequence, myths about the inherent greatness of sport have grown. One such myth is the belief that sport itself is ideally suited to help disadvantaged young people develop "socially" and "psychologically". And that sport is capable of teaching "teamwork" or "leadership".

Impotence medicine associated with reduced long-term risk of death after heart attack

Common impotence drugs such as Viagra may have a life-prolonging effect on patients who have suffered a myocardial infarction, a paper published by researchers at Karolinska Institutet suggests. The finding, which is published in the scientific journal Heart, calls for the need of prospective studies of impotence drugs in heart attack patients others than only those who suffer from impotence – including women.

Discovery of a new metabolic pathway of a known lipid has implications in cancer, obesity

A collaborative Stony Brook University research team has discovered a novel metabolic pathway of the lipid ceramide, which is involved in cell death. The finding illustrates that ceramide is stored in lipid droplets, a step that may help to uncover processes necessary for cell death and lipid metabolism, and therefore has implications in the development of cancer or obesity. The paper is published in Cell Metabolism.

How immune surveillance cells are educated to tolerate foreign bacteria

The fundamental task of the immune system is discrimination—discrimination between the tissues of its host ('self') and invasive pathogens ('non-self'). In order to turn its destructive powers on the proper targets, it must be capable of distinguishing friend from foe. This poses a particular challenge for the immune cells that are associated with the epithelial lining of the gut. They are exposed to the natural microbiota of the gut, which themselves play an important physiological role. Hence the immune system must in some way be actively prevented from attacking these bacteria although they do not fall into the 'self' category. A German-Italian research collaboration has now uncovered one mechanism that helps to maintain this equilibrium in the gut. The project was led by Professor Thomas Brocker, Director of the Institute for Immunology at LMU, and the researchers report their findings in Nature Communications, an open-access member of the Nature family of science journals.

Boosting a baby's health during the 'golden window'

Malaria treatment soon to be simpler, more flexible, and more efficient?

Malaria infections may soon be treated much more efficiently than they are at present. Researchers at the Universities of Bayreuth and Jerusalem have developed a novel drug release procedure for this purpose. The procedure enables the active ingredient Artemisone to be administered reliably at quantities and time intervals that are tailored exactly to the patients' individual needs. The scientists have published their findings in the journal Global Challenges. This research was part of a project which received a total of around 1.5 million euros in funding from the German Research Foundation (DFG) over a period of five years.

Researchers find a gene that causes Opitz C syndrome

Opitz C syndrome is a genetic disease that causes severe disabilities in patients and has been diagnosed in three people in the Iberian Peninsula, and 60 people in the world. A team led by the professors Daniel Grinberg and Susana Balcells, from the University of Barcelona and the Biomedical Research Networking Center of Rare Diseases (CIBERER) has now identified a gene that causes Opitz C syndrome in the only patient in Catalonia diagnosed with this severe congenital disease. This new scientific advance is a first step to discovering the genetic bases of this syndrome which, so far, has no treatment, prenatal diagnosis or genetic counseling.

Computational biologists predict antibiotic resistances using biotech

Just a few days ago, the World Health Organization (WHO) published a list of twelve antibiotic-resistant bacterial strains, which are considered to be the "greatest threats to human health". Andreas Keller, professor for Clinical Bioinformatics at Saarland University, is also studying these bacterial resistances. "If a patient receives faster access to the treatment best suited to fight the disease in question, it is not only to the benefit of the patient. It also helps dispensing currently available antibiotics in a more targeted manner, so that the development of resistances can be slowed down," Keller explains.

A closer look at brain organoid development

How close to reality are brain organoids, and which molecular mechanisms underlie the remarkable self-organizing capacities of tissues? Researchers already have succeeded in growing so-called "cerebral organoids" in a dish - clusters of cells that self-organize into small brain-like structures. Juergen Knoblich and colleagues have now further characterized these organoids and publish their results today in The EMBO Journal. They demonstrate that, like in the human brain, so-called forebrain organizing centers orchestrate developmental processes in the organoid, and that organoids recapitulate the timing of neuronal differentiation events found in human brains.

Childhood bullying may lead to increased chronic disease risk in adulthood

Being bullied during childhood might have lifelong health effects related to chronic stress exposure—including an increased risk for heart disease and diabetes in adulthood, according to a research review in the March/April issue of the Harvard Review of Psychiatry.

Investigational vaccine protects cattle from respiratory syncytial virus

A novel vaccine developed by scientists at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, protected cattle from respiratory syncytial virus (RSV) infection, according to research published online in npj Vaccines on March 8. The research was conducted by a team of experts at NIAID, the Pirbright Institute based in the United Kingdom, and the Institute for Research in Biomedicine in Switzerland. The version of RSV that naturally infects cattle is closely related to human RSV, so the results suggest that a similar human RSV vaccine construct may provide protection in humans, according to the study authors.

Funders need to take more responsibility for the efficiency of the research they fund

It has been estimated that up to 85% of medical research is wasted because it asks the wrong question, is badly designed, not published or poorly reported. Health research around the world depends heavily on funding from agencies which distribute public funds. But a new study has found that these agencies are not as open as they could be about what they are doing to prevent this waste and that governments responsible for the public money they distribute are not holding them to account.

Maths—why many great discoveries would be impossible without it

Despite the fact that mathematics is often described as the underpinning science, it is often not given enough credit when scientific discoveries are presented. But the contribution of mathematics and statistics is essential and has transformed entire areas of research – many discoveries would not have been possible without it. In fact, as a mathematician, I have contributed to scientific discoveries and provided solutions to problems that biology was yet to solve.

Stressed seabird parents think only of themselves

Stress is a factor not only in the best human families; it also appears among animals. To see how bird family members interact with each other in stressful situations, researchers from Vetmeduni Vienna and the University of Gdansk, Poland, studied parent-offspring interactions in a long-lived seabird, the little auk (Alle alle). The scientists gave parent and offspring birds a hormone pellet to increase their "stress levels", with the result that stressed offspring not only intensified their begging but also received more food than "relaxed" chicks. Nevertheless, increased begging was not the determining factor of the parent-offspring interaction. When parent birds were stressed, they automatically reduced offspring feeding and spent more time searching for food for themselves. The parent-offspring interaction among little auks therefore clearly depended on the state of the adult bird, even though little auks usually raise only a single chick.
