![]() | Possible discovery of a new super-Earth orbiting Proxima CentauriAstronomers have discovered another candidate exoplanet orbiting our neighbor Proxima Centauri. A paper announcing these results was just published in the journal Science Advances. If confirmed, it will be the second exoplanet discovered to be orbiting the star. |
![]() | How we spotted a potential new planet around the sun's neighboring starMost exoplanets—bodies orbiting stars other than the sun—are too far away for us to be able to send probes to. So it's no wonder that the discovery of a possible habitable planet around the sun's nearest neighbor star, Proxima Centauri, a few years ago generated a lot of excitement. Now we have spotted what we think is a second planet around this star. |
![]() | Behind howls of solar wind, quiet chirps reveal its originsThere's a wind that emanates from the sun, and it blows not like a soft whistle but like a hurricane's scream. |
![]() | Nearly barren Icelandic landscapes guide search for extraterrestrial lifeNew research on microbial lifeforms living in nearly barren volcanic landscapes in Iceland may help scientists understand how best to search for life on other planets. |
![]() | ExoMars Rover completes environmental testsThe Rosalind Franklin rover of the joint ESA-Roscosmos ExoMars mission completed a series of environmental tests at the end of 2019 at Airbus, Toulouse, France. This included final thermal and vacuum tests where the Rover is heated and cooled to simulate the temperatures of its journey through space and on the surface of Mars. For example, Rosalind Franklin can expect temperatures dropping to –120°C outside, and –50 °C inside the rover once on Mars. It must also be able to operate in less than one hundredth of Earth's atmospheric pressure—and in a carbon dioxide-rich atmosphere. |
Technology news

Medicine & Health news
![]() | Molecular understanding of drug interactions suggests pathway to better malaria treatmentsThe process of crystallization is central to drug development, petrochemical processing and other industrial actions, but scientists say they still are learning about the complex interactions involved in the building and dissolution of crystals. |
![]() | With these neurons, extinguishing fear is its own rewardWhen you expect a really bad experience to happen and then it doesn't, it's a distinctly positive feeling. A new study of fear extinction training in mice may suggest why: The findings not only identify the exact population of brain cells that are key for learning not to feel afraid anymore, but also show these neurons are the same ones that help encode feelings of reward. |
![]() | How decisions unfold in a zebrafish brainSome things we do appear almost automatic, like opening the fridge when feeling hungry or flipping on the air conditioning when the temperature rises. Although such decisions don't seem to take much thought, they are in fact generated by millions of neurons and numerous interactions among several brain regions—a dynamic system so complex that scientists aren't able to observe it fully and in real time, even in simple organisms. |
![]() | Zika virus' key into brain cells ID'd, leveraged to block infection and kill cancer cellsZika virus infection can stunt neonatal brain development, a condition known as microcephaly, in which babies are born with abnormally small heads. To determine how best to prevent and treat the viral infection, scientists first need to understand how the pathogen gets inside brain cells. |
![]() | Stage is set to develop clinically relevant, senescence-based biomarkers of agingSenescent cells, which stop dividing under stress, are long- recognized drivers of multiple diseases of aging. Mouse studies have shown that targeted removal of these cells and the inflammatory factors they secrete, known as the senescence-associated secretory phenotype (SASP), has beneficial results on multiple organ systems and functions. Success in the laboratory has given rise to companies and research projects aimed at developing either senolytics, drugs that clear senescent cells, or senomorphics, drugs that suppress the SASP. But drug development and clinical utilization require simple, reliable biomarkers to assess the abundance of senescent cells in human tissues. Publishing in PLOS Biology, researchers at the Buck Institute have extensively profiled the SASP of human cells and have generated a curated database available for use in the field. |
![]() | Mosquitoes engineered to repel dengue virusAn international team of scientists has synthetically engineered mosquitoes that halt the transmission of the dengue virus. |
![]() | No clear evidence of increase in adolescent suicide after '13 Reasons Why'Contrary to the findings of a 2019 study that associated the release of the Netflix series "13 Reasons Why" with an increase in monthly suicide rates among adolescent boys, a reanalysis of the data by the Annenberg Public Policy Center finds no evidence of contagion. The reanalysis, published today in PLOS ONE, found that after controlling for the dramatic increase in adolescent suicide in recent years, the show's release had no clear effect. |
![]() | Controlling molecular glue protects connections between brain cellsA way in which some connections between brain cells can resist degeneration—a hallmark of traumatic brain injuries and neurodegenerative diseases—has been discovered by researchers at The University of Queensland. |
![]() | Whooping cough evolving into a superbugWhooping cough bacteria are becoming smarter at colonizing and feeding off unwitting hosts, strengthening calls for a new vaccine, according to UNSW researchers. |
![]() | Researchers demonstrate how the brain assesses and predicts physiological states of the bodyInteroception is the self-awareness of physiological states; it's how animals and humans know they're hungry or thirsty, and how they know when they've had enough to eat or drink. But precisely how the brain estimates the state of the body and reacts to it remains unclear. In a paper published in the journal Neuron, neuroscientists at Beth Israel Deaconess Medical Center (BIDMC) shed new light on the process, demonstrating that a region of the brain called the insular cortex orchestrates how signals from the body are interpreted and acted upon. The work represents the first steps toward understanding the neural basis of interoception, which could in turn allow researchers to address key questions in eating disorders, obesity, drug addiction, and a host of other diseases. |
New point-of-care diagnostic test may revolutionize early diagnosis of Mediterranean rickettsiosis spotted feverRickettsiae are bacteria that cause severe, potentially lethal human infections, including Mediterranean spotted fever (MSF) and Rocky Mountain spotted fever. Delays in diagnosing and treating MSF can cause significant morbidity and mortality, due in part to the lack of a test for early detection. A new study in the American Journal of Pathology reports the discovery of a sensitive and specific marker that may enable early diagnosis, treatment, and accurate public health notification of spotted fever rickettsial infections including MSF. | |
Obesity crisis blamed for a rise in fatty liver disease amongst young adultsOne in five young people have fatty liver disease (steatosis), with one in 40 having already developed liver scarring (fibrosis), research published today [15 January] has found.

![]() | Hookah smoke may be associated with increased risk of blood clotsFor the first time, in a study conducted in mice, researchers found that tobacco smoke from a hookah caused blood to function abnormally and be more likely to clot and quickly form blood clots, which can increase the risk of heart attack or stroke, according to new research published today in the American Heart Association's journal Arteriosclerosis, Thrombosis and Vascular Biology (ATVB). |
![]() | Study contests use of smoked cannabis in treatment of cocaine addictionA Brazilian study published in the journal Drug and Alcohol Dependence shows that cannabis smoked recreationally does not work as a harm reduction strategy for crack and cocaine addicts undergoing rehabilitation. Instead of reducing their craving for cocaine, whether nasally insufflated in powder form or smoked in the form of crack crystals, cannabis use made the patients' clinical condition worse. |
![]() | Von Willebrand factor antigen for assessing the urgency of a liver transplantLike most other countries, Austria—as part of the Eurotransplant organization—allocates organs to patients on the liver transplant waiting list on the basis of medical urgency. Currently, patients are listed according to urgency using a score made up of three laboratory parameters—the Model for End Stage Liver Disease (MELD) score. However, the MELD score has obvious limitations and the rate of mortality of patients on the waiting list continues to be approximately 20 percent. |
![]() | Keeping your immune system healthy is a way to keep the flu bug awayGetting a good night's sleep and maintaining a healthy lifestyle are two ways to battle the flu bug, as its presence increases across the nation. |
![]() | Partnership with China prompts change in care for high-risk type of leukemiaResearchers from St. Jude Children's Research Hospital and the Chinese Children's Cancer Group led the first randomized, Phase III clinical trial comparing targeted therapies for acute lymphoblastic leukemia (ALL) driven by the Philadelphia chromosome. Results showed that the drug dasatinib provides more benefit than the standard of care, which led to changes in the way this leukemia is treated. The findings were reported today in JAMA Oncology. |
![]() | Comparing cancer costs is challenging, despite new price transparency rulesComparison shopping for airfare, a TV or a car can be straightforward online. The same cannot be said for checking what hospitals charge for a standard radiation treatment for prostate cancer, according to a report published in JAMA Oncology. |
![]() | Study gauges efficacy of drugs against pork tapewormTaenia solium—also called pork tapeworm—is a parasite which causes disease around the world, particularly in very poor communities with deficient santiation and where pigs roam free. Researchers have now analyzed the efficacy and adverse effects of three chemotherapeutics against T. solium and report their results in a review published in PLOS Neglected Tropical Diseases. |
![]() | Do studies underestimate the prevalence of typhoid?Blood culture surveillance programs are critical for estimating the prevalence of typhoid and paratyphoid fevers, but cases can be missed when patients don't seek medical care, or seek medical care and don't have a blood culture test. Researchers writing in PLOS Neglected Tropical Diseases have now calculated inflation factors that can be used to adjust these incidence rates to account for under-detection. |

![]() | Healthy commercial ads don't change teens' desire to eat junk foodHow teens' brains respond to TV commercials for fast food can predict what they are going to eat for dinner, according to new University of Michigan research. |
![]() | Estrogen may facilitate the growth of liver metastases in non-sex-specific cancersIt is known that the tumor microenvironment plays an important role in the progression of cancer. But could estrogen present in this microenvironment facilitate the growth of liver metastases in women affected by colon, pancreatic and lung cancers? This is what a team of researchers from the Research Institute of the McGill University Health Centre (RI-MUHC) suggests, in a study that shows for the first time that the liver immune microenvironment reacts to metastatic cells differently in male and in female mice and that, indeed, the main female hormone estrogen can indirectly contribute to the growth of metastases. Their findings, recently published in Nature Communications, provide a rationale for further exploration of the role of sex hormones in female cancer patients and the potential benefits of anti-estrogen drugs such as tamoxifen in the treatment of hormone-independent cancers that metastasize to the liver. |

![]() | Lifetime suicide risk factors identifiedA review of studies into suicide risk factors at different stages of peoples' lives, as well as of the effectiveness of assessment and treatment approaches, has found that while some factors such as genetics and family history play a part in suicide risk throughout life, other factors including clinical depression, substance misuse, lack of social support and economic factors become stronger after adolescence. |
![]() | Why you need more vitamin D in the winterWinter is upon us and so is the risk of vitamin D deficiency and infections. Vitamin D, which is made in our skin following sunlight exposure and also found in oily fish (mackerel, tuna and sardines), mushrooms and fortified dairy and nondairy substitutes, is essential for good health. Humans need vitamin D to keep healthy and to fight infections. The irony is that in winter, when people need vitamin D the most, most of us are not getting enough. So how much should we take? Should we take supplements? How do we get more? And, who needs it most? |
![]() | Walnuts may be good for the gut and help promote heart healthWalnuts may not just be a tasty snack, they may also promote good-for-your-gut bacteria. New research suggests that these "good" bacteria could be contributing to the heart-health benefits of walnuts. |

![]() | Study unravels new insights into a Parkinson's disease proteinResearch by University at Buffalo biologists is providing new insights into alpha-synuclein, a small acidic protein associated with Parkinson's disease. |
![]() | Cancer study may accidentally help researchers create usable blood stem cellsA massive research effort over more than a quarter century has tried to make personalized blood stem cells for use in treating leukemias, among many other uses. One way researchers have gone about this is to sample a patient's adult cells and then "deprogram" them to create induced pluripotent stem cells (iPSCs), which are capable of forming any of the body's cell types, including blood cells. Unfortunately, these iPSCs also have the potential to become cancer. So researchers have largely refocused their efforts on making hematopoietic stem cells (HSCs), which can't make any cell type, but can produce many types of blood cells. The good news is that HSCs don't seem to cause cancer like iPCs. The bad news is that researchers have been unable to create HSCs that can take hold and grow in the body. |
![]() | Are bigger brains better?When it comes to certain parts of the brain, bigger doesn't necessarily equate to better memory. According to a new study led by Michigan State University, a larger hippocampus, a curved, seahorse-shaped structure embedded deep in the brain, does not always reliably predict learning and memory abilities in older adults. |
![]() | Sepsis associated with one in five deaths globally, double previous estimateTwice as many people as previously believed are dying of sepsis worldwide, according to an analysis published today in The Lancet and announced at the Critical Care Reviews annual meeting in Belfast. Among them are a disproportionately high number of children in poor areas. |
![]() | Belgian brain doctor awarded for easing coma survivors' returnNot all patients who fall into a coma return, and when they do it can mark a moment of joy for their loved ones—but their troubles are rarely over. |
![]() | Survivors of firearm violence worse long-term outcomes than motor vehicle crash survivorsIn 2017, for every victim who died of a firearm injury in the U.S, three individuals survived. But the burden of firearm injuries is not limited to death. A new study led by investigators from Brigham and Women's Hospital finds that 6-to-12 months after traumatic injury, rates of chronic pain, post-traumatic stress disorder (PTSD) and other poor physical and mental health outcomes were alarmingly high among survivors of firearm violence—even higher than among survivors who had sustained similar injuries in motor vehicle crashes. The study, which highlights the need for following survivors after discharge and providing continued care, is published in Annals of Surgery. |
![]() | Low doses of radiation used in medical imaging lead to mutations in cell culturesCommon medical imaging procedures use low doses of radiation that are believed to be safe. A new study, however, finds that in human cell cultures, these doses create breaks that allow extra bits of DNA to integrate into the chromosome. Roland Kanaar and Alex Zelensky of Erasmus University Medical Center and Oncode Institute and colleagues report these new findings in a study published 16th January in PLOS Genetics. |
![]() | Brain imaging may improve diagnosis and treatment of mental health disordersBrain imaging may one day be used to help diagnose mental health disorders—including depression and anxiety—with greater accuracy, according to a new study conducted in a large sample of youth at the University of Pennsylvania and led by Antonia Kaczkurkin, Ph.D. and Theodore Satterthwaite, MD. |
![]() | New study identifies potential path forward for brachial plexus injury recoveryOn average, an estimated three out of every 1,000 newborns will suffer a brachial plexus injury during birth, damaging the bundle of nerves that connect the brain and spinal cord to the shoulders, arms and hands. In the most traumatic cases, even with surgery and physical therapy as an infant, there is no treatment that can guarantee a full recovery. |
Texas abortion patients' more likely to attempt to end their pregnancy on their ownA new study by the Texas Policy Evaluation Project (TxPEP) finds that approximately seven percent of patients seeking abortion at Texas clinics had tried to end their current pregnancy on their own before coming to the clinic. This is higher than the national rate of 2.2 percent. The article was recently published in BMC Women's Health. | |
![]() | German parliament votes against new system for organ donorsGerman lawmakers on Thursday rejected a proposal that would have made most people potential organ donors unless they objected, instead backing a less radical plan to tackle a shortage of donor organs. |
![]() | Pakistan says Facebook to help in fight against polioPakistan says Facebook will help the country in its fight against polio after authorities blamed anti-vaccine content posted last year on the social network site for a leap in the number of cases. |
![]() | Vaping emergencies may initially go unrecognizedDiagnosing EVALI—the e-cigarette, or vaping, product use associated lung injury illness that's recently garnered national attention—can be challenging. Initial symptoms may resemble pneumonia or go unrecognized, according to case analysis in the Journal of the American College of Emergency Physicians (JACEP) Open, a new open access journal. |
![]() | Pulling the plug on calcium pumps—potential new treatment strategy for pancreatic cancerUK scientists have identified a new way to kill pancreatic cancer cells by 'pulling the plug' on the energy generator that fuels calcium pumps on their cell surface. The study, published in the British Journal of Cancer, reports how switching off the cancer's energy supply causes the pancreatic cancer cells to become 'poisoned' by an irreversible build-up of calcium. |
![]() | Larotrectinib in tumours with NTRK gene fusion: Data are not yet sufficientIn the summer of 2019, larotrectinib was approved as the first drug in Europe to be used in numerous different solid tumours if the tumour tissue displays a so-called NTRK gene fusion. Since such a fusion of a neurotrophic tyrosine receptor kinase gene with another gene leads to increased proliferation of the tumour cells, the aim is to selectively block the corresponding signal pathway. The new inhibitor was approved for cases in which the disease is locally advanced or metastatic and there are no other satisfactory treatment options. |
![]() | Virtual physical therapy after knee replacement brings similar outcomes, lower costsA virtual system for in-home physical therapy (PT) provides good outcomes for patients undergoing rehabilitation following total knee arthroplasty (TKA)—with lower costs than traditional in-person PT, reports a study in the January 15, 2020 issue of The Journal of Bone & Joint Surgery. |
![]() | Mayo Clinic Minute: Boost optimismAn increasing body of research suggests that optimistic people are healthier and happier than those who are pessimistic. But even if you are a negative thinker, you can teach yourself to make happiness a habit. Dr. Richa Sood, a Mayo Clinic general internist, has tips on how you can become more optimistic. |

![]() | Male songbirds can't survive on good looks alone, says a new studyBrightly coloured male songbirds not only have to attract the female's eye, but also make sure their sperm can last the distance, according to new research. |
![]() | The mysterious, legendary giant squid's genome is revealedHow did the monstrous giant squid—reaching school-bus size, with eyes as big as dinner plates and tentacles that can snatch prey 10 yards away—get so scarily big? |
![]() | Discovery reveals how remora fishes know when to hitch a ride aboard their hostsRemoras are among the most successful marine hitchhikers, thanks to powerful suction discs that allow them to stay tightly fastened to the bodies of sharks, whales and other hosts despite incredible drag forces while traveling through the ocean. But how do these suckerfish sense the exact moment when they must "stick their landing" and board their speedy hosts in the first place? |
![]() | Jumping genes threaten egg cell qualityA woman's supply of eggs is finite, so it is crucial that the quality of their genetic material is ensured. New work from Carnegie's Marla Tharp, Safia Malki, and Alex Bortvin elucidates a mechanism by which, even before birth, the body tries to eliminate egg cells of the poorest quality. Their findings describing this mechanism are published by Nature Communications. |
![]() | Scientists uncover how an explosion of new genes explain the origin of land plantsThe new study, led by scientists from the universities of Bristol and Essex and published today in Current Biology, challenge the established view of the origin of plants on land, and reveal that compared to the origin of animals, plants are better at inventing new genes during periods of evolution. |
![]() | Glimpse into ancient hunting strategies of dragonflies and damselfliesDragonflies and damselflies are animals that may appear gentle but are, in fact, ancient hunters. The closely related insects shared an ancestor over 250 million years ago—long before dinosaurs—and provide a glimpse into how an ancient neural system controlled precise and swift aerial assaults. |
![]() | How cells assemble their microtubule skeletonMicrotubules, filamentous structures within the cell, are required for many important processes, including cell division and intracellular transport. A research team led by scientists from Heidelberg University recently discovered how the spiral-shaped, modular microtubules are formed and how their formation is controlled. These processes were visualized using state-of-the-art cryo-electron microscopy (cryo-EM). |
![]() | Researchers decode the circuitry of neuromuscular organoidsThe Gouti lab from the Max Delbrück Center for Molecular Medicine in the Helmholtz Association (MDC) has developed functional neuromuscular organoids (NMOs) that self-organize into spinal cord neurons and muscle tissue. Together, the two cell types form a complex neuronal network that directs muscle tissue to contract. The neuromuscular organoids, described in the journal Cell Stem Cell, represent a breakthrough for the study of human neuromuscular system development and disease. |
![]() | Scientists unexpectedly witness wolf puppies play fetchWhen it comes to playing a game of fetch, many dogs are naturals. But now, researchers report that the remarkable ability to interpret human social communicative cues that enables a dog to go for a ball and then bring it back also exists in wolves. The study appears January 16 in the journal iScience. |
![]() | Mobile protected areas needed to protect biodiversity in the high seasWorld leaders are currently updating the laws for international waters that apply to most of the world's ocean environment. This provides a unique opportunity, marine scientists argue this week, to introduce new techniques that allow protected zones to shift as species move under climate change. |
![]() | New mechanisms describe how the genome regulates itselfAn organism's genome contains all of the information necessary for each of its cells and tissues to develop and function properly. Written in DNA, each individual gene encodes for something, whether it is a structural protein that helps define a tissue's shape, an enzyme that catalyzes the chemical reactions of life, or a signaling protein that cells use to communicate. |
![]() | Scientists create decoy molecule that neutralizes arenavirusesA host of disease-causing viruses called arenaviruses lurk in animal populations in various parts of the world, sometimes crossing over into humans. When they do cross over, they can be lethal, and only very few treatments exist. Researchers led by scientists at the Weizmann Institute of Science have now devised a clever decoy for these viruses that may keep them from spreading in the body. |
![]() | Blue-green algae found to produce greenhouse gas methaneAn international team of researchers has found that cyanobacteria (blue-green algae) produce the greenhouse gas methane. In their paper published in the journal Science Advances, the group describes tests they carried out with blue-green algae in their lab and what they found. |
![]() | Incubated Prometheoarchaeum syntrophicum samples may provide clues about origin of eukaryotic cellsA team of researchers affiliated with a large number of institutions in Japan has found a possible link between primitive archaea and the development of eukaryotes. In their paper published in the journal Nature, the group describes culturing Prometheoarchaeum syntrophicum samples and what they learned by studying them. |
![]() | Physicists design 'super-human' red blood cells to deliver drugs to specific targets within the bodyA team of physicists from McMaster University has developed a process to modify red blood cells so they can be used to distribute drugs throughout the body, which could specifically target infections or treat catastrophic diseases such as cancer or Alzheimer's. |
![]() | 'Living fossil' may upend basic tenet of evolutionary theoryThe field of evolutionary biology has seen its share of spirited debates. But if there's one principle that virtually every expert in the field agrees on, it's that natural selection occurs at the level of the genome. |
Terrain may help identify habitats that are resilient to the effects of climate changeA new paper in The Condor: Ornithological Applications, published by Oxford University Press, finds that models which use terrain features offer both practical and theoretical advantages in identifying climate resilient habitats for migratory birds whose populations are impacted by climate change. | |
![]() | Experts say Med Sea altered by Suez Canal's invasive speciesAs Egypt marks the 150th anniversary of the opening of the Suez Canal, marine biologists are bemoaning one of the famed waterway's lesser known legacies—the invasion of hundreds of non-native species, including toxic jellyfish and aggressive lionfish. |
![]() | New software to better understand conversations between cellsOne of the most fascinating and important properties of living cells is their capacity for self-organization. By talking to each other, cells can, among other things, determine where they are in relation to each other and whether they need to turn certain genes on or off. Thus, large groups of cells are able to work together and organize into all kinds of tissues. Researchers at Delft University of Technology have now developed software that can predict and visualize conversations between cells on the basis of the molecules involved. |
![]() | Trees struggle when forests become too smallAs forest areas shrink and become fragmented, many tree species face problems. They often rely on animals that can no longer disperse their seeds effectively. |
![]() | New model shows how crop rotation helps combat plant pestsA new computational model shows how different patterns of crop rotation—planting different crops at different times in the same field—can impact long-term yield when the crops are threatened by plant pathogens. Maria Bargués-Ribera and Chaitanya Gokhale of the Max Planck Institute for Evolutionary Biology in Germany present the model in PLOS Computational Biology. |
![]() | Potential to adapt is revealed by evolutionary genomicsGlobal climate change is going to drastically alter the environmental conditions for humans and nature. Animals and plants unable to cope with the new conditions are thus forced to shift their range to different areas or to adapt genetically. Otherwise they are in danger of extinction. Mobile species such as birds can change their migration routes and colonize new, more suitable habitats. Earth worms, on the other hand, are much more stationary and therefore heavily rely on adaptation. However, in most cases the actual reaction of a given species has not been clarified to date. |
![]() | Worst marine heatwave on record killed one million seabirds in North Pacific OceanThe common guillemot (known as the common murre in North America) breeds in both the Pacific and the Atlantic and is among the most abundant seabirds in the northern hemisphere. But like many other seabirds, its numbers have declined over the last few decades. Part of that decline is due to the marine environment—a seabird's home and hunting ground—becoming increasingly unpredictable and difficult to survive in. |
![]() | What should we do with the millions of animals killed by bushfires?Bushfires this season have left an estimated 1 billion dead animals in their wake, their carcasses dotting the blackened landscape. |
![]() | Bird species are facing extinction hundreds of times faster than previously thoughtExtinction, or the disappearance of an entire species, is commonplace. Species have been forming, persisting and then shuffling off their mortal coil since life began on Earth. However, evidence suggests the number of species going extinct, and the rate at which they disappear, is increasing dramatically. |
![]() | Cells protect themselves against stress by keeping togetherCell-to-cell contacts are necessary for the survival of human cells under protein-damaging conditions and stress. This was one of the conclusions made by a research team working under the leadership of Lea Sistonen, Professor in Cell and Molecular Biology at Åbo Akademi University. The results of their research were recently published in the Cell Reports journal. |
![]() | Bartonella bacteria found in hemangiosarcoma tumors from dogsResearchers from North Carolina State University have found a very high prevalence of Bartonella bacteria in tumors and tissues—but not blood samples—taken from dogs with hemangiosarcoma, a cancer of the blood vessels. The work further supports the connection between persistent infection and some types of cancer and adds to the evidence that Bartonella can remain and thrive, undetected, within tissue. |
