Shigella bacteria can infect humans but not mice. A team can now explain why. Their findings may explain the multifariousness of a key weapon of our immune system.
Researchers are learning more about ancient graffiti -- and their intriguing comparisons to modern graffiti -- as they produce a state-of-the-art 3D recording of the Temple of Isis in Philae, Egypt.
A new study finds that overprescribing and inappropriate prescribing of antibiotics is not only leading to antibiotic resistance, but also causing significant patient harm. It's one of the most comprehensive studies to document the impact of antibiotic overuse in clinical practice.
Researchers report that the flow of cerebrospinal fluid in the brain is linked to waking brain activity. The study demonstrates that manipulating blood flow in the brain with visual stimulation induces complementary fluid flow. The findings could impact treatment for conditions like Alzheimer's disease, which have been associated with declines in cerebrospinal fluid flow.
Researchers have developed fiber-like pumps that allow high-pressure fluidic circuits to be woven into textiles without an external pump. Soft supportive exoskeletons, thermoregulatory clothing, and immersive haptics can therefore be powered from pumps sewn into the fabric of the devices themselves.
Indigenous peoples as far north as Wyoming and Idaho may have begun to care for horses by the first half of the 17th Century, according to a new study by researchers from 15 countries and multiple Native American groups.
The simple amino acid glycine looks to be a previously unknown contributor to depression.
A new artificial intelligence tool can predict the functions of enzymes based on their amino acid sequences, even when the enzymes are unstudied or poorly understood. Researchers said the AI tool, dubbed CLEAN, outperforms the leading state-of-the-art tools in accuracy, reliability and sensitivity. Better understanding of enzymes and their functions would be a boon for research in genomics,...
A new study suggests that predatory dinosaurs, such as Tyrannosaurus rex, did not have permanently exposed teeth as depicted in films such as Jurassic Park, but instead had scaly, lizard-like lips covering and sealing their mouths.
Aging cells express a protein that is produced by human cytomegalovirus and is targeted by certain immune cells in the body. Harnessing the immune response to this protein could have multiple health benefits during aging.
Researchers at the University of Washington have developed GlucoScreen, a system that could enable people to self-screen for prediabetes.
As tick season kicks in across the country, scientists have completed research that offers a promising lead in the fight against Lyme disease.
Research led by a University of Cincinnati doctoral student shows that immigrants and refugees who participated in a civic leadership program felt more empowered after learning about their rights, civic entitlements and the social, cultural, and political context of Cincinnati.
More than 1.3 million Thais have fallen ill this year from a spike in extreme air pollution.
White blood cells called neutrophils have an unappreciated role in eradicating solid tumors, according to a surprise discovery from a team led by Weill Cornell Medicine scientists.
As questions abound about the Earth's closest star, scientists are seeking answers critical to forecasting solar flares that threaten satellites and other electronics.
The winter killing season for manatees along Central Florida's Atlantic coast is winding down with an astounding turn of events—a tiny fraction of the animals died compared to during the last two years.
Cryptomarkets—marketplaces on the dark web that can facilitate the sale of illicit goods between vendors and buyers—are proving to be attractive alternatives to traditional in-person drug dealing, according to Simon Fraser university researchers, who say machine learning and tracking markets through web crawlers may help curb the growing trend.
Children are spending more time in digital environments than ever, yet laws and policies haven't kept pace in protecting them there, writes a team of researchers in a new perspective in the journal Science.

In a study, published in the journal Science China Chemistry and led by Prof. Pingping Fang (School of Chemistry, Zhejiang University) and Prof. Jianfeng Li (College of Chemistry and Chemical Engineering, Xiamen University), experiments were performed by using an Xplora Raman spectrometer with a 50x microscope objective and an excitation wavelength of 638 nm from a He–Ne laser.
As tick season kicks in across the country, the executive director of the University of Massachusetts Amherst-based New England Center of Excellence in Vector-Borne Diseases (NEWVEC) and his team have completed research that offers a promising lead in the fight against Lyme disease.
A review published in the journal Forestry Research focuses on understory vegetation biodiversity, regeneration, biomass, nutrient content and storage, carbon and nitrogen relationships, functional traits, litter decomposition, and interactions with overstory trees. It also covers the ecological effects of understory vegetation on soil chemistry, soil microbial communities, and soil and water...
Gamma-ray bursts are the most energetic and luminous events known to occur in the Universe. Short-lived flashes of gamma rays that typically last from a a tenth of a second to less than an hour, gamma-ray bursts may for a brief period of time outshine entire galaxies. The explosions are believed to be caused by the collapse of massive stars, the collision of neutron stars, or the merging of a...
In a study recently published in the journal Horticulture Research, researchers performed a genome-wide association study (GWAS) for SSC of the red-ripe fruits in a population consisting of 481 tomato accessions with large natural variations and found a new quantitative trait locus, STP1, encoding a Sugar Transporter Protein.
