![]() | Earth as hybrid planet: New classification places Anthropocene era in astrobiological contextFor decades, as astronomers have imagined advanced extraterrestrial civilizations, they categorized such worlds by the amount of energy their inhabitants might conceivably be able to harness and use. They sorted the hypothetical worlds into three types according to a scheme named in 1964 for Soviet astronomer Nikolai Kardashev. |
![]() | Jupiter's aurora presents a powerful mysteryScientists on NASA's Juno mission have observed massive amounts of energy swirling over Jupiter's polar regions that contribute to the giant planet's powerful aurora - only not in ways the researchers expected. |
![]() | Accretion-powered pulsar reveals unique timing glitchThe discovery of the largest timing irregularity yet observed in a pulsar is the first confirmation that pulsars in binary systems exhibit the strange phenomenon known as a 'glitch'. The study is published in the journal Monthly Notices of the Royal Astronomical Society. |
![]() | Asteroid Florence has two moonsFlorence, an asteroid that came within 4.4 million miles (7.0 million kilometers) of Earth last week, has two small moons, according to radar images obtained by NASA. |
![]() | X-rays reveal temperament of possible planet-hosting starsA new study using data from NASA's Chandra X-ray Observatory and ESA's XMM-Newton suggests X-rays emitted by a planet's host star may provide critical clues to just how hospitable a star system could be. A team of researchers looked at 24 stars similar to the Sun, each at least one billion years old, and how their X-ray brightness changed over time. |
![]() | Does the organic material of comets predate our solar system?The Rosetta space probe discovered a large amount of organic material in the nucleus of comet 'Chury.' In an article published by MNRAS on Aug. 31, 2017, two French researchers advance the theory that this matter has its origin in interstellar space and predates the birth of the solar system. |
![]() | Two significant solar flares imaged by NASA's SDOThe sun emitted two significant solar flares on the morning of Sept. 6, 2017. The first peaked at 5:10 a.m. EDT and the second, larger flare, peaked at 8:02 a.m. EDT. NASA's Solar Dynamics Observatory, which watches the sun constantly, captured images of both events. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however—when intense enough—they can disturb the atmosphere in the layer where GPS and communications signals travel. |

![]() | Russia-linked Facebook accounts stoked US divisionsFacebook said Wednesday an internal review showed that hundreds of Russia-linked fake accounts were used to buy ads aimed at inflaming political tensions ahead of and following the 2016 US presidential election. |
![]() | Supercharging silicon batteriesAs the world shifts towards renewable energy, moving on from fossil fuels, but at the same time relying on ever more energy-gobbling devices, there is a fast-growing need for larger high-performance batteries. Lithium-ion batteries (LIBs) power most of our portable electronics, but they are flammable and can even explode, as it happened to a recent model of smartphone. To prevent such accidents, the current solution is to encapsulate the anode – which is the negative (-) electrode of the battery, opposite to the cathode (+) - into a graphite frame, thus insulating the lithium ions. However, such casing is limited to a small scale to avoid physical collapse, therefore restraining the capacity - the amount of energy you can store - of the battery. |
![]() | Beware the cult of 'tech fixing' – it's why America is eyeing the nuclear buttonWith even Vladimir Putin now warning of global catastrophe from the recent tensions in Korea, we are in arguably the worst period of nuclear brinkmanship since the end of the Cold War. It is partly thanks to a strand of thinking among the American right that a nuclear attack on Pyongyang would succeed where decades of diplomacy has failed. |

![]() | The problem with sex shops 'for women'The launch of a sex toy collection to tie-in with the Comedy Central series Broad City calls to mind another connection between sex toys and women on television. In a 1998 episode of Sex and the City, Carrie Bradshaw and her friends visited a sex shop to buy "Rabbit" vibrators. Several of the women that I interviewed for my research on women and sex shopping mentioned that episode as a watershed moment in the normalisation of sex shopping for women. |
![]() | Three reasons employers need to recognise menopause at workMenopause, when periods stop for good, is a normal stage in every woman's reproductive life. The symptoms usually begin in a woman's forties, with the average age of menopause itself being 51. Experiences differ from woman to woman. Some report sailing through transition, others are pleased to no longer menstruate or be able to fall pregnant, or just embrace getting older. |
![]() | Female doctors show more empathy than male doctorsOur latest research found that female doctors are better at empathy than male doctors, and this probably makes them better doctors. |
Genetic effects are influenced by lifestyleThe risk for developing obesity is influenced by our lifestyle as well as our genes.

![]() | Art courses could help medical students become better clinical observersObservation skills are an essential component of any medical education, aiding doctors during patient exams and in making medical diagnoses, yet several studies have indicated inadequacies in this area among medical trainees and practicing physicians. In an effort to explore ways to improve these skills among medical students, researchers from Perelman School of Medicine at the University of Pennsylvania and Children's Hospital of Philadelphia (CHOP), in collaboration with educators at the Philadelphia Museum of Art, turned to the field of visual arts to examine if training in art observation, description, and interpretation could be applied to medical training. |
![]() | Substance in coffee delays onset of diabetes in laboratory miceIn recent years, researchers have identified substances in coffee that could help quash the risk of developing Type 2 diabetes. But few of these have been tested in animals. Now in study appearing in ACS' Journal of Natural Products, scientists report that one of these previously untested compounds appears to improve cell function and insulin sensitivity in laboratory mice. The finding could spur the development of new drugs to treat or even prevent the disease. |
Older adults who are frail more likely to have negative outcomes after traumaFrailty is associated with negative outcomes among older patients who suffered trauma, a new study has found. | |
Liver cancer patients can start with lower dose of chemotherapy and live just as longPatients with the most common type of liver cancer who are taking the chemotherapy drug sorafenib can begin their treatment with a lower dose than is currently considered standard, and it will not affect how long they live when compared to patients who start on the full dose. That finding comes from a new study from the Abramson Cancer Center of the University of Pennsylvania, published this week in the Journal of Clinical Oncology, and it opens the door for patients with hepatocellular carcinoma to begin with a reduced dose of sorafenib, which helps to minimize the drug's side effects while also saving money for patients, providers, and insurers. | |
Researchers find campus sexual violence significantly affects academicsSexual assault on a college campus can cause a considerable number of physical and emotional issues for the victim. While much needed programs, and past studies, have predominately focused on the mental health effects of such violent acts on students, new research by the University of New Hampshire shows that aggressive sexual acts can also adversely impact school work and overall college experience. | |
![]() | Researchers measure the basis of color visionDr. Wolf M. Harmening from University Eye Hospital Bonn, together with American colleagues, studied color vision by probing individual sensory cells - photoreceptors - in the human eye. The results confirm that the photoreceptor cells of the retina are especially sensitive to colors corresponding to their visual pigments, even when stimulated in isolation. A new observation is that proximity effects play a key role: sensitivity of tested photoreceptors varied depending on which cell classes were located in their immediate neighborhood. The results have now been published in advance online and will soon be published in the Journal of Neuroscience. |
![]() | Study points to path for better diagnosis of eating disorders, the deadliest of mental illnessesA paper appearing recently in the peer-reviewed journal Comprehensive Psychiatry details a "radical" new method for diagnosing eating disorders that predicts 68 percent of people's problems in psychological and social functioning due to eating-disorder features. |
Common cerebral white matter abnormalities found in children with autistic traitsStructural abnormalities in the brain's white matter match up consistently with the severity of autistic symptoms not only in children with autism spectrum disorder (ASD), but also, to some degree, in those with attention-deficit/hyperactivity disorder (ADHD) who also have autistic traits. | |

![]() | Three-quarters of Americans see head injuries in football as major problemThree-quarters of fans say head injuries in football are a major problem and another six in 10 are worried about off-field violence involving players. Despite that, football remains America's favorite professional sport, according to results of a UMass Lowell-Washington Post poll released today. |
![]() | CBD may protect against psychiatric risk from high-THC cannabis strainsA study reported Sept. 5 by neuroscientists at Indiana University finds that a non-psychoactive compound in cannabis called cannabidiol, or CBD, appears to protect against the long-term negative psychiatric effects of THC, the primary psychoactive ingredient in cannabis. |
Blood tumor markers may warn when lung cancer patients are progressingFor many years, oncologists have known that cancers can secrete complex molecules into the blood and that levels of these molecules can be easily measured. These so-called 'tumor markers' are traditionally associated with a single dominant cancer type, for example Prostate Specific Antigen (PSA) linked to prostate cancer, Carcinoembryonic antigen (CEA) to colorectal cancer, CA125 to ovarian cancer, CA19.9 to pancreatic cancer and CA27.29 to breast cancer. However, the real challenge has been to determine a practical use for these markers. They don't appear to be useful as a means of screening otherwise healthy people for evidence of underlying cancers. | |
![]() | Health of more than half of US adults affected by obesityConsidering weight across the life course, the prevalence of obesity among adults in the US rises considerably, suggesting that the effects on population health may be even more pervasive than previously understood, according to a new study led by a Boston university School of Public Health (BUSPH) researcher. |
Comparing cancer drug effectiveness from cells to mice to manScience is very good at determining how drugs work in experimental models. New research out of Dartmouth's Norris Cotton Cancer Center led by Alan Eastman, PhD, helps to bridge the gap when it comes to ensuring that drugs work by the same mechanism in human patients. | |
![]() | Put flu shot on the back-to-school checklist(HealthDay)—Annual flu vaccines are appropriate for everyone aged 6 months or older, the American Academy of Pediatrics reminds parents. |
![]() | New study finds improved vaccine that protects against nine types of HPV is highly effectiveCervical cancer is the second most common cause of cancer-related death worldwide, with almost 300,000 deaths occurring each year. More than 80 percent of these deaths occur in developing nations. The advent of human papillomavirus (HPV) vaccines has significantly reduced the number of those who develop and die from cervical cancer. And thanks to an international effort to improve the vaccine, the medical community is one step closer to preventing more HPV-associated diseases. The researchers, including those from Moffitt Cancer Center, published the final results of a study showing the newest vaccine is highly effective at preventing HPV infection and disease. The study was published this week in The Lancet. |
![]() | A bioactive molecule may protect against congestive heart failure after heart attacksHeart attacks provoke an acute immune response. Leukocytes rush to the heart muscle to remove dead cells and begin building scar tissue. This is followed by a second immune response, the resolving phase that allows healing. |
![]() | Chronic bronchitis new insights could lead to first diagnostic test and better treatmentsWhen a patient arrives at a doctor's office with a persistent cough and the sensation of gunk building up in the lungs, the doctor's thought process is essentially the same as it would have been decades ago. There has been no understanding of the affected biological pathways causing the gunk buildup in the lung, nor has there been a diagnostic test for chronic bronchitis. UNC School of Medicine researchers are trying to change that. |
Patient satisfaction with pain management linked to nurse staffingHospital patients' satisfaction with pain management is linked to nurse staffing, according to an article authored by nurse researchers from the Connell School of Nursing at Boston College and published in the journal Pain Management Nursing. | |
A decade later, older Americans are still going hungryHunger does not respect age. A recent report comparing data from 2007 to 2015 finds 5.4 million people age 60 or older in the U.S., or 8.1 percent, are food insecure. Although this percentage went down from 2014 to 2015, it's still unacceptable, according to a University of Illinois economist. | |
Alectinib: ALEX and ALUR trials show CNS benefit in NSCLCData from two separate phase 3 studies to be presented at the ESMO 2017 Congress in Madrid, show alectinib's particular central nervous system (CNS) activity in patients with advanced non-small cell lung cancer involving a mutation of the anaplastic lymphoma kinase gene (ALK-positive NSCLC). | |

Patient's immune status associated with outcome following third-generation CAR T-cell therapyTreatment with third-generation CAR T–cell therapy led to a complete response in six of 15 patients with a CD19-positive B-cell malignancy and overall survival was associated with the patient's immune status, according to data from a phase I/IIa clinical trial presented at the Third CRI-CIMT-EATI-AACR International Cancer Immunotherapy Conference: Translating Science into Survival, held Sept. 6–9. | |
Inactivated vaccinia virus effective against advanced cancers alone or combined with immune checkpoint inhibitorsModified vaccinia virus Ankara (MVA), a poxvirus, was found to be safe when administered in an inactivated form in mice, and delivering it into the tumor in addition to systemic delivery of an immune checkpoint inhibitor yielded synergistic antitumor effects in mice with large tumors and those with multiple tumors, according to data presented at the Third CRI-CIMT-EATI-AACR International Cancer Immunotherapy Conference: Translating Science into Survival, held Sept. 6-9. | |
Gut microbes may promote immune responses against colorectal cancerBacteria in the gut could stimulate tumor cells to produce factors that regulate cell mobility called chemokines that recruit T cells to the tumor, which is linked to improved outcomes, according to data presented at the Third CRI-CIMT-EATI-AACR International Cancer Immunotherapy Conference: Translating Science into Survival, held Sept. 6-9. | |
Study finds less extensive damage in young female mice from chemotherapy-induced kidney injuryYoung females may have the greatest level of protection against acute kidney injury (AKI) caused by the chemotherapy drug Cisplatin, commonly used to treat lung, ovarian, bladder and stomach cancer. Nearly a third of all people who are treated with Cisplatin develop AKI. The study—the first to investigate combined sex and age differences in the response to kidney injury—is published ahead of print in the American Journal of Physiology—Renal Physiology and was chosen as an APSselect article for September. | |

![]() | Clever cockatoos bend hooks into straight wire to fish for foodIn the early 2000s the New Caledonian crow Betty in Oxford shocked the world when she spontaneously bent a hook into a straight piece of wire while trying to retrieve a small out-off-reach basket with a handle from a vertical tube. Interestingly, when human children were tested on a similar task setup they showed great difficulties with coming up with a suitable solution until the age of nearly eight years. New Caledonian crows are specialized tools users in the wild and their ability to handle tools is innate. Nevertheless, in this case Betty seemed to innovatively produce a novel behavioural sequence on an unknown material. |
![]() | Something to sneeze about: Democratic voting in African wild dog packsScientists studying African wild dogs in Botswana have found members of this endangered species use sneezes to vote on when the pack will move off and start hunting. |
![]() | Identification of individuals by trait prediction using whole-genome sequencing dataResearchers from Human Longevity, Inc. (HLI) have published a study in which individual faces and other physical traits were predicted using whole genome sequencing data and machine learning. This work, from lead author Christoph Lippert, Ph.D. and senior author J. Craig Venter, Ph.D., was published in the journal Proceedings of the National Academy of Sciences (PNAS). |
![]() | Could solar storms that cause the northern lights cause whale strandings?A series of sperm whale strandings saw 29 of the animals beached across the North Sea in early 2016. As these whales are not normally found in the North Sea, the strandings were a bit of a mystery. But a study is now proposing that the solar storms that cause the northern and southern lights (aurora) could be to blame for the ill-fated whales ending up on the beaches. |
![]() | Sugar molecule helps stomach cells to differentiate between good and bad bugsHalf of all people are chronically infected with Helicobacter pylori, a Gram negative bacterium that plays a causative role in the development of gastric cancer. It comes in two types, one that is relatively harmless and another that increases the risk of cancer six-fold. The dangerous strain causes a particularly strong inflammation in the stomach mucosa by activating nuclear factor kappa B (NF-κB), the "master switch" of the tissue-based innate immune response, which rapidly triggers transcription of genes that initiate local inflammation. How exactly H. pylori triggers NF-κB has long been a mystery, however. |
![]() | The shark network—exposing the social lives of sharksResearchers have shown for the first time that sharks show very strong preferences for particular individuals in their social networks over years and prefer to hang out with other individuals of the same sex and size, in a new study released today. |
![]() | Molecular map shows how to disable dangerous bioweaponDuring World War II, the Soviet Red Army was forced to move their biological warfare operations out of the path of advancing Nazi troops. Among the dangerous cargo were vials of Francisella tularensis, the organism that causes tularemia and one of the world's most infectious pathogens. |
![]() | Malaria: Drug candidate may reduce spread of the parasiteSignificant headway has been made in controlling malaria. However, two vexing problems remain: currently available treatments are unable to block transmission of the parasite that causes the disease, and the parasite often becomes resistant to drugs. According to a new study led by researchers at Columbia University Medical Center (CUMC), there is a class of compounds that could address both of these problems. |
![]() | Due to climate change, one-third of animal parasites may be extinct by 2070The Earth's changing climate could cause the extinction of up to a third of its parasite species by 2070, according to a global analysis reported Sept. 6 in the journal Science Advances. Parasite loss could dramatically disrupt ecosystems, and the new study suggests that they are one of the most threatened groups of life on Earth. |
![]() | Pollen stays on bee bodies right where flowers need it for pollinationAfter grooming, bees still have pollen on body parts that match the position of flower pollen-sacs and stigmas, according to a study published September 6, 2017 in the open-access journal PLOS ONE by Petra Wester from Heinrich-Heine-University, Germany, and colleagues. |
![]() | Monkey sees ... monkey knows? A metacognitive illusion in monkeysSocrates is often quoted as having said, "I know that I know nothing." This ability to know what you know or don't know—and how confident you are in what you think you know—is called metacognition. |
![]() | Will mallards hybridize their cousins out of existence?Mallards—the familiar green-headed ducks of city parks—are one of a group of closely related waterfowl species, many of which are far less common. Interbreeding with Mallards can threaten the genetic distinctiveness of those other species and cause concern for their conservation. A new study from The Condor: Ornithological Applications investigates hybridization between Mallards and Mottled Ducks, a species specially adapted for life in Gulf Coast marshes, and finds that while hybridization rates are currently low, human activity could cause them to rise in the future. |

![]() | How a tiny portion of the world's oceans could meet global seafood demandSeafood is an essential staple in the diets of people around the world. Global consumption of fish and shellfish has more than doubled over the last 50 years, and is expected to keep rising with global population growth. Many people assume that most seafood is something that we catch in the wild with lines, trawls and traps. In fact, aquaculture (aquatic farming) accounts for just over half of all the seafood consumed worldwide. |
![]() | Newly described 'parasol' sponges are graceful but deadly (to small crustaceans)When most people think of sponges, they think of squishy, soap-filled kitchen sponges, or perhaps the graceful barrel sponges that grow around coral reefs. But in the dark depths of the ocean, some sponges have evolved into deadly predators, which trap and digest small, helpless prey. In a new paper in the journal Zootaxa, marine biologists describe three new species of predatory sponges that live in deep water off the coast of California and in the Gulf of California. |

![]() | A protein that extends life of yeast cellsTo understand and control aging is the aspiration of many scientists. Researchers at the Biozentrum of the University of Basel have now discovered that the protein Gcn4 decreases protein synthesis and extends the life of yeast cells. Understanding how individual genes affect lifespan opens new ways to control the aging process and the occurrence of aging-related diseases. The results of this study have recently been published in Nature Communications. |
![]() | Team finds way to measure key cell regulator's activityUT Health San Antonio researchers and co-authors in New York state on Monday (Sept. 4) reported an innovative approach that will enable scientists to study the most common regulator of our bodies' cells, a molecule called guanosine-5'-triphosphate (GTP). |
![]() | The protein TAZ sends 'mixed signals' to stem cellsJust as beauty exists in the eye of the beholder, a signal depends upon the interpretation of the receiver. According to new USC research published in Stem Cell Reports, a protein called TAZ can convey very different signals—depending upon not only which variety of stem cell, but also which part of the stem cell receives it. |

![]() | Curved substrates restrict spreading and induce differentiation of stem cellsAn invention by Florida Institute of Technology's Shengyuan Yang was found to naturally narrow the spreading of stem cells and has the potential to induce and regulate their differentiation. |
![]() | Herbicide rotation ineffective against resistance in waterhempFarmers have been battling herbicide-resistant weeds for generations. A common practice for most of that time has been to rotate between different herbicides every season. But despite farmers' best efforts, herbicide resistance has grown through the years, with some weed populations showing resistance to not one but four or five different herbicides. A new study from the University of Illinois explains why herbicide rotation doesn't work. |
![]() | Building a morphogen gradient by simple diffusion in a growing plant leafIn an article published on September 5 in Biophysical Journal, Associate Professor Kensuke Kawade at the Okazaki Institute for Integrative Bioscience and National Institute for Basic Biology in Japan showed that a transcriptional co-activator ANGUSTIFOLIA3 (AN3) forms a signaling gradient along the leaf proximal-to-distal axis to determine the cell-proliferation domain. In particular, by experimental and theoretical approaches, they demonstrated that pure diffusion in a growing tissue is sufficient to explain the AN3 gradient formation. This work provides evidence that the diffusion-based model of morphogen is viable in developmental patterning of multicellular organisms. |
![]() | Collaring the mice that carry Lyme disease-causing ticksWhite-footed mice in Howard County, Maryland are being collared as part of a study to improve control of the ticks that spread Lyme disease. The mouse collaring research, never before done in Maryland, is a partnership of the Agricultural Research Service (ARS), Howard County Department of Recreation & Parks (HCRP), and University of Maryland (UMD). |
