Astronomy & Space news
![]() | A stellar system with three super-EarthsOver 3500 extra-solar planets have been confirmed to date. Most of them were discovered using the transit method, and astronomers can combine the transit light curves with velocity wobble observations to determine the planet's mass and radius, and thereby constrain its interior structure. The atmosphere can also be studied in a transit by using the fact that the chemical composition of the atmosphere means its opacity varies with wavelength. By measuring the depth of the transit at different wavelengths, it is possible to infer the composition and temperature of the planet's atmosphere. |
![]() | Unprecedentedly wide and sharp dark matter mapA research team of multiple institutes, including the National Astronomical Observatory of Japan and University of Tokyo, released an unprecedentedly wide and sharp dark matter map based on the newly obtained imaging data by Hyper Suprime-Cam on the Subaru Telescope. The dark matter distribution is estimated by the weak gravitational lensing technique (Figure 1, Movie). The team located the positions and lensing signals of the dark matter halos and found indications that the number of halos could be inconsistent with what the simplest cosmological model suggests. This could be a new clue to understanding why the expansion of the Universe is accelerating. |
![]() | How we discovered the strange physics of jets from supermassive black holesSupermassive black holes, which lurk at the heart of most galaxies, are often described as "beasts" or "monsters". But despite this, they are pretty much invisible. To show that they are there at all, astronomers typically have to measure the speed of the clouds of gas orbiting those regions. |
![]() | Desert-dwelling bacteria offer clues to habitability on marsThe survival tricks adopted by microbes known as hypolithic cyanobacteria, which are found underneath quartz rocks in Earth's deserts, could point to how microbial life on Mars may live, say researchers. |

![]() | Twitter CEO asks for help on 'civility'; YouTube stumblesTwitter CEO Jack Dorsey is asking for help improving the openness and civility of conversation on Twitter, saying the company failed to prevent misinformation, echo chambers and abuse of its global messaging service. |
Crowdlending: Anatomy of a successful strategyCrowdlending is participation in peer-to-peer financing that allows individuals to directly finance projects or companies by means of interest-bearing loans. Crowdfunding appeared at the start of the 2010s, and developed quickly via internet platforms. In 2017, it represented more than 190 million Euros of loans to companies in France. However, developing a crowdlending platform has not always been easy; this is why researchers have asked which strategies an entrepreneur could implement to develop an innovative business model for the existing parties, banks, and for their future competitors: other platforms in the sector. | |
![]() | When the Internet goes down"A third of the Internet is under attack. Millions of network addresses were subjected to distributed denial-of-service (DDoS) attacks over two-year period," reports Warren Froelich on the UC San Diego News Center website.

Medicine & Health news
![]() | A neuron can cause a domino effectLoss of the sense of smell can indicate a neural disease like Alzheimer's or Parkinson's disease. However, contrary to previous belief, degenerations in the nervous system do not play a leading role in the loss of the sense of smell with increasing age. Rather, individual nerve cells or classes of nerves are responsible. |
![]() | Blocking a protein could improve the effectiveness of intravascular cellular 'policing'Researchers at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC), led by Dr. Alicia G. Arroyo, have identified a function of a protease that could be targeted for the treatment of some infections and even tumor metastasis. The study, published today in Nature Communications shows that blockade of the protease MT4-MMP increases the surveillance activity of a type of white blood cell in the circulation, the blood-patrolling monocytes. These cells act like 'police patrols' to detect foreign or undesired material in the blood. The findings, according to Dr. Alicia G Arroyo, "have possible clinical implications and could contribute to strategies to eliminate foreign or undesired materials from the blood, such as infectious agents or tumor cells." The study thus suggests new strategies to combat infection or prevent metastasis, which are currently being evaluated for patent protection. |
![]() | Nervous system puts the brakes on inflammationCells in the nervous system can "put the brakes" on the immune response to infections in the gut and lungs to prevent excessive inflammation, according to research by Weill Cornell Medicine scientists. This insight may one day lead to new ways to treat diseases caused by unchecked inflammation, such as asthma and inflammatory bowel disease. |
![]() | New method identifies splicing biomarkers for liver cancerBecause liver cancer is particularly diverse, genetically, and prone to relapse, identifying biomarkers that can predict disease progression is a critical goal in the fight against it. |

![]() | Researchers develop model to determine quantity of bisphenol A that reaches the fetus through the motherVarious studies have shown that when pregnant women come into contact with bisphenol, it can go pass through the placenta and reach the fetus. Exposure to bisphenol can have negative effects on fertility, the development of the brain, and behavioural changes in adulthood. So far, however, no method has been available for quantifying the amount of the compound that can reach the fetus through the mother. Now, researchers from the Centre for Environmental, Food and Toxicological Technology (Tecnatox) have created a mathematical model that can calculate the amount of bisphenol and tested it with a sample of 100 pregnant women to determine the consequences it can have on the future health of their children. |
![]() | Researchers study a nanoscaffold for heart cellsBiophysicists from MIPT have studied the structure of a nanofibrous scaffold, as well as its interaction with rat cardiac cells. The study, which is part of the research into heart tissue regeneration, revealed that cardiomyocytes, the heart muscle cells, envelop nanofibers as they grow, while fibroblasts, which are connective tissue cells, tend to spread out on fibers forming several focal adhesion sites. |
![]() | Nerve damage in type 2 diabetes can be detected in the eyeBy examining the cornea for nerve damage with a special microscope, it may be possible to diagnose type 2 diabetes. This according to a study among diabetics in Skelleftea, north Sweden. |
How reliable is diagnostic testing for Zika?Globally, Brazil has been the hardest hit by the current Zika outbreak, and the country reports almost all cases of Zika-associated malformations in newborns. DZIF scientists from the Charité - Universitätsmedizin Berlin have shown that molecular diagnostic tests for the Zika virus in Brazil are not always reliable. Almost two-thirds of all laboratories showed false-positive or false-negative results. | |
Yellow fever virus is detected in urine and semen almost a month after infectionThe presence of yellow fever virus in urine and semen samples from an infected patient who survived was detected almost a month after infection, according to a study conducted by researchers at the University of São Paulo's Biomedical Science Institute (ICB-USP) in Brazil in collaboration with colleagues at Butantan Institute, Emílio Ribas Infectology Institute, and Pontifical Catholic University of São Paulo (PUC-SP). The discovery is described in an article published in Emerging Infectious Diseases. | |

![]() | Idle, uncleaned milk trucks don't compromise the quality of raw milk, study showsRaw milk quality isn't compromised when tanker trucks sit empty and uncleaned for hours between loads, according to new research at Oregon State University. |
![]() | Yes the 'cheerleader effect' is real – and you can make it work in your favourWhen it comes to presenting yourself online – such as your profile pic for Facebook or even Tinder – which type of photo do you chose? The selfie you've taken after careful consideration of lighting, hair and maybe makeup? (No doubt, you look great!) Or the group photo with friends, possibly less styled, but that captures a moment among peers? |
Tapeworms could prevent, treat inflammatory bowel disease in childrenNew research suggests that parasitic worms could someday help prevent or treat pediatric inflammatory bowel disease (IBD). The study, published ahead of print in the American Journal of Physiology—Gastrointestinal and Liver Physiology, was chosen as an APS select article for March. | |
![]() | Human ancestors had the same dental problems as us – even without fizzy drinks and sweetsDental erosion is one of the most common tooth problems in the world today. Fizzy drinks, fruit juice, wine, and other acidic food and drink are usually to blame, although perhaps surprisingly the way we clean our teeth also plays a role. This all makes it sound like a rather modern issue. But research suggests actually humans have been suffering dental erosion for millions of years. |
![]() | Four ways alcohol is bad for your healthIn Australia, almost 6,000 deaths a year can be attributed to alcohol, as well as around 400 hospitalisations a day. While drinking has declined in some segments of the population, with related stabilising of rates of death and illness, these numbers are far too high. Similar reports are emerging in other countries. |
![]() | Earlier palliative care at home linked to fewer hospital admissionsOffering palliative care earlier to dying patients at home is linked to fewer hospital admissions at the end of their lives, raising questions about the time restrictions placed on accessing community-based palliative care in some parts of the world, new research led by Curtin University has found. |
![]() | Survival protein clue to immune cell recovery following chemotherapyOne well-known side effect of conventional cancer treatments, such as chemotherapy, is the severe damage that it causes to the immune system. |

![]() | New procedure brings chemo to melanomaThe choice between saving one's limb or one's life may seem obvious. However, surgical oncologist Cristina O'Donoghue, MD, MPH, knows the decision is emotionally wrenching for patients with advanced melanoma or sarcoma in a limb that likely would be fatal if allowed to metastasize. |
Silence around stillbirth a major issue for bereaved parentsWhat's the biggest obstacle facing bereaved parents after losing a child at birth? Society's unwillingness to discuss it openly, says UniSA Ph.D. candidate Danielle Pollock, whose first child, Sofia, was stillborn four years ago. Danielle is calling on health providers to take the lead and provide more information about stillbirth during antenatal classes. | |
![]() | School peer-to-peer awareness program for adolescent depression effective, study showsA high school peer-to-peer program to develop depression awareness campaigns can lead to improved knowledge and attitudes toward depression, greater likelihood to seek help if needed and reduced stigma, according to a new study published online today in Psychiatric Services in Advance. |

Quinn on Nutrition: Sodium: How low can we go?As with much of this science of nutrition, experts don't always agree on what's best for us. Not that they don't have good information. Sometimes we have lots of valid data. But Mr. Jones' response to a dietary change may be entirely different from Mrs. Smith's. Case in point, several respected organizations have come up with different recommendations on how low we should go with our intake of sodium. Depending on which experts you listen to, we should be consuming somewhere between 1500 to 2300 milligrams of sodium a day, according to an article on this topic by registered dietitian Karen Collins. That's quite a bit less than the estimated 3500 milligrams we Americans currently consume. | |
Researchers find transferable antibiotic resistance gene in pathogen of developing nationsA team of investigators has found that the mcr-1 drug resistance gene, which encodes resistance to a drug that is used as a last resort, has been found for the first time in Shigella flexneri.

Biology news
![]() | CRISPR-Cas9 can cut RNA, tooThe ability to edit genes at will, whether to reverse genetic diseases or improve food and energy crops, is undergoing a revolution. It is being driven by CRISPR-Cas9, a technology modeled on a cellular mechanism found in bacteria. CRISPR-Cas9 recognizes and cuts foreign genomic material from invading viruses and thus protects the bacteria from being infected. |

![]() | Two species of ravens nevermore? New research finds evidence of 'speciation reversal'For over a century, speciation—where one species splits into two—has been a central focus of evolutionary research. But a new study almost 20 years in the making suggests "speciation reversal"—where two distinct lineages hybridize and eventually merge into one—can also be extremely important. The paper, appearing March 2 in Nature Communications, provides some of the strongest evidence yet of the phenomenon, in two lineages of Common Ravens. |
![]() | Evolving a more versatile CRISPR-Cas9For all of Cas9's potential in research and therapeutics, it—as well as other enzymes in the CRISPR-associated family—has limitations. In order to recognize and bind to a DNA sequence, Cas9 needs a particular stretch of base letters to accompany the target. This requirement makes much of the genome inaccessible to the enzyme, significantly reducing its range of applications. |
![]() | Bovine embryos as a model for early human developmentThe mechanisms that underlie early embryonic development in humans and cattle are very similar. Therefore, LMU researchers argue that bovine embryos might well be a better model for early human development than the mouse system. |
![]() | Capturing the balance of natureIn a study spanning 12 years, researchers from Kyoto University and Ryukoku University have developed a method to calculate the fluctuating stability of a natural ecological community in Maizuru Bay.Their findings, published in Nature, provide insight into and new methodologies for ecological and population research. |
Samoa creates huge shark sanctuaryThe island nation of Samoa has declared its waters a shark sanctuary, joining a string of other Pacific countries in protecting the marine predators. | |
Plants fix DNA differently from animalsIn mammalian cells, the transcription factor p53 most responsible for healthy growth of the organism. The equivalent in plants is Suppressor Of Gamma Response 1 (SOG1), a factor that does not share a common evolutionary ancestor with p53. While p53 has been exhaustively studied, much less is known about SOG1. A new study led by researchers at the Nara Institute of Science and Technology (NAIST) reports in The Plant Journal concerning the target genes of SOG1 and the key DNA sequence responsible for its binding to promoters. In addition, it shows SOG1 has an immune function, unlike p53. | |
![]() | 3000 years of evolution with dingoes matters to bilbiesWild bilbies are more reluctant to leave their burrows when dog faeces has been placed nearby than when they are presented with the faeces of feral cats, which are major introduced predators of these small native Australian marsupials. |
![]() | Researchers find the ancestral function of the retinoic acid, an essential molecule in the evolution of vertebratesIn molecular biology, retinoic acid plays a key role in signalling pathways in the embryonic development of vertebrates. However, not much is known about its origins in the metazoan evolution. An international team has described for the first time the ancestral function of retinoic acid in the lineage of animals with bilateral symmetry, according to an article published in the journal Science Advances. |

![]() | Previously unknown 'supercolony' of Adélie penguins discovered in AntarcticaFor the past 40 years, the total number of Adélie Penguins, one of the most common on the Antarctic Peninsula, has been steadily declining—or so biologists have thought. A new study led by researchers from the Woods Hole Oceanographic Institution (WHOI), however, is providing new insights on of this species of penguin. In a paper released on March 2nd in the journal Scientific Reports, the scientists announced the discovery of a previously unknown "supercolony" of more than 1,500,000 Adélie Penguins in the Danger Islands, a chain of remote, rocky islands off of the Antarctic Peninsula's northern tip. |
![]() | Here's how viruses inactivate the immune system, causing cancerIt's no new news that viruses cause cancer. For example, human papillomavirus (HPV) causes almost all of the more than 500,000 annual worldwide cases of cervical cancer. This makes sense: By driving the proliferation of infected cells, viruses speed manufacture of more viruses, but excessive cellular proliferation is also a hallmark of cancer. Now a University of Colorado Cancer Center review published in the journal Viruses explores another strategy that viruses use to ensure their own survival, also with the unfortunate byproduct of promoting cancer, namely the viral ability to manipulate the human immune system. This new understanding may help to increase the effectiveness of immune-based therapies against cancer. |
