Experiment confirms fundamental symmetry in nature

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

Scientists working with ALICE, a heavy-ion detector on the Large Hadron Collider ring, have made precise measurements of particle mass and electric charge that confirm the existence of a fundamental symmetry in nature. The findings, reported in a paper published online in Nature Physics on Aug. 17, led the researchers to confirm a fundamental symmetry between the nuclei of the particles and their antiparticles in terms of charge, parity and time.

Closer to a treatment for the 'asthma of the esophagus'

D'Or Institute for Research and Education
Peer-Reviewed Publication

Scientists from Brazilian institutions and the Yale University School of Medicine have elucidated the chemical process behind a mysterious gastrointestinal disease that is becoming more frequent every day: the eosinophilic esophagitis (EoE), also known as the 'asthma of the esophagus'. The researchers identified a molecule which plays a key role in this condition and that can be a target in a new therapeutic strategy.

Sequestered prion protein takes the good mood away, suggests new hypothesis on depression

Publicase International
Peer-Reviewed Publication

The discovery of antidepressant drugs led to the first biochemical hypothesis of depression, known as the monoamine hypothesis. However, this hypothesis does not seem to fully explain the complexity of human depression. Now a new study offers one more important key that may increase our understanding of the pathogenesis behind clinical depression and neurodegenerative disorders.

When fat is the solution: Using adipose cells to attenuate chagasic cardiomyopathy

Publicase International
Peer-Reviewed Publication

It could be a plot for a vampire story: In the middle of the night, blood-sucking creatures feed on peoples' faces and spread a deadly disease to the hearts of millions, who are then fated to endure a painful death.

Brazilian company doubles shelf life of pasteurized fresh milk

Fundação de Amparo à Pesquisa do Estado de São Paulo
Business Announcement

A Brazilian company has increased the shelf life of grade A pasteurized fresh whole milk from seven to 15 days. This feat was achieved by incorporating silver-based microparticles with bactericidal, antimicrobial and self-sterilizing properties into the rigid plastic bottles used as packaging for the milk. The microparticles are included as a powder in the polyethylene preform that is used to make plastic bottles by blow or injection molding.

Parasitic flatworms flout global biodiversity patterns

Smithsonian Tropical Research Institute
Peer-Reviewed Publication

The odds of being attacked and castrated by a variety of parasitic flatworms increases for marine horn snails the farther they are found from the tropics. A Smithsonian-led research team discovered this exception to an otherwise globally observed pattern -- usually biodiversity is greatest in the tropics and decreases toward the poles.

More endangered pygmy sloths in Panama than previously estimated

Smithsonian Tropical Research Institute
Peer-Reviewed Publication

Pygmy sloths wander inland in addition to inhabiting the mangrove fringes of their island refuge. A Smithsonian visiting scientist realized that the population size of the pygmy sloth was underestimated; a new, higher estimate for the number of sloths on Panama's Escudo de Veraguas Island points to how little is known about the species, and it underscores the need to conserve the sloths' isolated home.

Nanometric sensor designed to detect herbicides can help diagnose multiple sclerosis

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

A nanobiosensor for the early diagnosis of certain types of cancer, as well as nervous system diseases such as multiple sclerosis and neuromyelitis optica, was developed by researches in São Paulo State, Brazil. The nanometric sensor is capable of identifying biomarkers of these pathological conditions. An article about the nanobiosensor has just been published as a cover feature by IEEE Sensors Journal.
