Researchers analyzed data from more than 1,000 breast cancer patients and found that breast cancer behaves differently than other cancers that are currently treated with immunotherapy. They identified seven clusters of breast cancer patients based on the immune evasion mechanisms that breast cancer uses to avoid detection.
Researchers from FSU’s Department of Earth, Ocean and Atmospheric Science suggest that projected increases in air temperatures, rainfall inundation and blistering solar radiation could significantly reduce hawksbill hatching success at a selection of major nesting beaches.
When infants are playing with objects, their early attempts to pay attention to things are accompanied by bursts of high-frequency activity in their brain. But what happens when parents play together with them? New research, publishing December 13 in the open-access journal PLOS Biology, by Dr Sam Wass of the University of East London in collaboration with Dr Victoria Leong (Cambridge University and Nanyang Technological University, Singapore) and colleagues, shows for the first time that when adults are engaged in joint play together with their infant, their own brains show similar bursts of high-frequency activity. Intriguingly, these bursts of activity are linked to their baby’s attention patterns and not their own.
Researchers have developed genetically modified pigs that are protected from classical swine fever virus (CSFV), according to a study published December 13 in the open-access journal PLOS Pathogens by Hongsheng Ouyang of Jilin University, and colleagues. As noted by the authors, these pigs offer potential benefits over commercial vaccination and could reduce economic losses related to classical swine fever.
Of the 34 million people worldwide with HIV, and the 200 million with schistosomiasis, the majority live in Africa— where millions of people are simultaneously infected with both diseases. Now, researchers reporting in PLOS Neglected Tropical Diseases have shown that schistosomiasis infections are associated with increased HIV onward transmission, HIV acquisition in HIV negative women with urogenital schistosomiasis, and progression to death in HIV positive women.
Thyalacoleo carnifex, the “marsupial lion” of Pleistocene Australia, was an adept hunter that got around with the help of a strong tail, according to a study released December 12, 2018 in the open-access journal PLOS ONE by Roderick T. Wells of Flinders University and Aaron B. Camens of the South Australia Museum, Adelaide. These insights come after newly-discovered remains, including one nearly complete fossil specimen, allowed these researchers to reconstruct this animal’s entire skeleton for the first time.
In a UK-wide survey published in the journal PLOS ONE, researchers at Beth Israel Deaconess Medical Center (BIDMC), and colleagues investigated primary care physicians’ views on AI’s looming impact on health professions.
Inhabiting a vast network of estuaries along the Atlantic coast, blue crabs are ecologically important and represent one of the valuable and prized fisheries in the United States. Blue crabs spawn in estuaries at a time of year when water-quality issues such as low dissolved oxygen (hypoxia) and low pH (acidification) can be the most persistent and severe. A group from the lab of Christopher Gobler, a professor in the School of Marine Science (SoMAS) at Stony Brook University, investigated the effects of these individual and combined stressors on early life stages of the blue crab. Their study, recently published in PLoS One, provides evidence that larval blue crabs experience increased mortality when exposed to low oxygen and/or low pH conditions at levels routinely found in degraded estuaries.
Current treatment options for the parasitic disease leishmaniasis are largely ineffective, expensive, and tend to be plagued by resistant parasites and side effects. Now, researchers reporting in PLOS Neglected Tropical Diseases have showed that a natural flavonoid is effective at treating Leishmania amazonensis infections.
Bacterial spores may be able to halt degradation by outcompeting other microbes
Are you among the 400 million people around the world who have relegated an old mobile phone to the top drawer in the past year? Do you realise your reluctance to recycle that discarded phone could be linked to the dramatic decline of gorilla populations in the Democratic Republic of the Congo?
Researchers have found that genetic mutations affecting the capsid, the structure surrounding the HIV genome, make it possible for a protein called TRIM5α to trigger the immune system of elite controllers.
Algunos virus son capaces de apoderarse de una enzima que supuestamente previene enfermedades autoinmunitarias con el fin de evitar ser detectados. Este descubrimiento de los investigadores de Mayo Clinic y de sus colaboradores se publica en PLOS Biology.
ROCHESTER, Minn. — An enzyme intended to prevent autoimmune disease can be hijacked and used by some viruses to avoid immune detection. That discovery from Mayo Clinic researchers and collaborators appears in PLOS Biology. There's also good news. The same team also defined how much viral genetic material is needed to reverse the process and instead activate the immune system against the virus.
Researchers have generated six Zika virus antibodies that could be used to test for and possibly treat a mosquito-borne disease that has infected more than 1.5 million people worldwide, according to a study published in PLOS ONE.

PROVIDENCE, R.I., BOSTON, MASS. and STANFORD, CALIF. -- Tablets and other mobile computing devices are part of everyday life, but using them can be difficult for people with paralysis. New research from the BrainGate* consortium shows that a brain-computer interface (BCI) can enable people with paralysis to directly operate an off-the-shelf tablet device just by thinking about making cursor movements and clicks.
Months of old-fashioned fieldwork helped define the range and characteristics of the recently discovered Atlantic Coast leopard frog. A study published in the journal PLOS ONE was led by a zoologist with the New York Natural Heritage Program based at the SUNY College of Environmental Science and Forestry.
Three clinical trial participants with paralysis chatted with family and friends, shopped online and used other tablet computer applications, all by just thinking about pointing and clicking a mouse.
A new study examining differences in the language used in nearly 40-million tweets suggests national stereotypes—Canadians tend to be polite and nice while Americans are negative and assertive—are reflected on Twitter, even if those stereotypes aren’t necessarily accurate.
Male birds-of-paradise are justly world famous for their wildly extravagant feather ornaments, complex calls, and shape-shifting dance moves—all evolved to attract a mate. New research published in the open-access journal PLOS Biology suggests for the first time that female preferences drive the evolution of physical and behavioral trait combinations that may also be tied to where the male does his courting: on the ground or up in the trees.
Researchers have developed a model that predicts which of the viruses that can jump from animals to people can also be transmitted from person to person—and are therefore possible sources of human diseases.
If lactating dairy cattle get too hot, they don’t produce as much milk, and that can add up to economic losses of more than $1 billion a year in the U.S. alone, University of Florida researchers say. This loss can easily double if dry cows -- those in late pregnancy that are not lactating -- suffer from heat stress.
Augmented reality technology can accelerate testing of connected and automated vehicles by 1,000 to 100,000 times, and reduce additional testing costs — beyond the price of physical vehicles—to almost zero, according to a new white paper published by Mcity.
A new national study shows that people whose mothers had more partners – married or cohabiting – often follow the same path.Results suggest that mothers may pass on personality traits and relationship skills that make their children more or less likely to form stable relationships.
Tiny microscopic worms, invisible to the naked eye, are helping scientists to better understand an extraordinarily complex biological pathway that connects fat to overall health and aging in humans.

A new Florida State University College of Medicine study in mice produced results that suggest nicotine exposure in men could lead to cognitive deficits in their children and grandchildren. Further studies will be required to know if the same outcomes seen in mice would apply to humans.
Scientists are using computational models of the brain to simulate how the structure of the brain may impact brain activity and, ultimately, human behavior. The research focuses on interconnectivity, looking at how different regions are linked to and interact with one another.
One question that scientists and fitness experts alike would love to answer is whether exercise or nutrition has a bigger positive impact on bone strength.
Scientists at Lawrence Livermore National Laboratory have shown that the structure of microscopic pores in high explosive materials can significantly impact performance and safety. These findings open the door to the possibility of tuning high explosives by engineering their microstructure.
In studies of mouse cells, Johns Hopkins researchers have found that low levels of cellular copper appear to make fat cells fatter by altering how cells process their main metabolic fuels, such as fat and sugar.
A groundbreaking study reveals how dolphins, whales and other cetaceans compete for survival in an evolutionary “arms race” with changing pathogenic threats like mercury and brevotoxin (e.g. Red Tide). Researchers show that cetaceans use several strategies for success in this race. They have developed tools to help wildlife managers and health professionals assess disease risk from the perspective of how individual animals are engineered to recognize the molecules of microorganisms in the environment and launch an immune response.
