Observed cosmic rays may have come from two-million-year-old supernova

(Phys.org)—High-energy protons, nuclei, and other particles are constantly showering down on Earth's atmosphere from space, but the origins of these cosmic rays is unknown. One possibility is that the cosmic rays come from supernovae, although the evidence for this claim is limited. Now by analyzing the cosmic ray energy spectrum, scientists have been able to deduce that some high-energy cosmic rays may have originated from a two-million-year-old supernova located roughly 100 trillion miles away.

Looking for deliberate radio signals from KIC 8462852

Could there be intelligent life in the star system KIC 8462852? A recent analysis of data collected by the Kepler space telescope has shown that this star, informally known as Tabby's Star, evidences aperiodic dimming of 20 percent and more. While several natural explanations for this strong change in luminosity have been proposed, one possibility is that a technologically adept civilization has built megastructures in orbit around star, causing the dimming.

New Horizons completes record-setting Kuiper Belt targeting maneuvers

NASA's New Horizons spacecraft has successfully performed the last in a series of four targeting maneuvers that set it on course for a January 2019 encounter with 2014 MU69.

Researchers at Karolinska Institutet, SciLifeLab and Centre for Clinical Research, Västerås have been able to explain why a combination of castration therapy and radiation therapy increases survival rates for patients with prostate cancer, compared to if they only receive radiation therapy. The findings, which are presented in the journal Science Translational Medicine, show that castration therapy impairs the DNA-repair machinery of the cancer cells, making them more sensitive to radiation.

People attribute moral obligation and blame, regardless of ability

New research from the University of Waterloo debunks the age-old moral philosophy that if you are unable to do something, then you are not morally obligated to do it.

Protein movement of hair bundles in the inner ear may preserve hearing for life

Hearing is made possible when hair bundles protruding from the tops of hair cells capture the energy of sound waves, converting them into electrical signals that stimulate the auditory nerve to the brain. These hair bundles are made up of individual hair-like projections, or stereocilia, which sway in unison with other stereocilia, and remain permanently with us throughout our lives. Extremely loud noise can force whipsaw motion of the stereocilia, causing them to be damaged and the resulting hearing loss to be permanent. The prevailing theory had been that these hair bundles were made up of cellular scaffolding proteins that do not change or circulate.

New study projects considerable public health impact for RTS,S malaria vaccine

The researchers found that over a 15 year time horizon, an average of 116,500 cases of clinical malaria disease and 484 deaths would be averted for every 100,000 children vaccinated under a four-dose schedule of immunizations at 6, 7.5, 9 and 27 months of age. This translates to approximately 1.2 cases averted per vaccinated child and one malaria death averted for every 200 children vaccinated. These data apply to children living in regions of Africa that experience moderate to high malaria transmission—countries where prevalence rates for the most deadly malaria parasite, Plasmodium falciparum, range from 10 to 65 percent—and assumes a vaccine coverage rate at fourth dose of approximately 70%.

Their results are reported in the American Journal of Pathology.

Better options for people with treatment-resistant schizophrenia

In real-world settings, patients with schizophrenia whose symptoms do not respond to standard antipsychotic medications have better outcomes if they are switched to clozapine instead of another standard antipsychotic. They have fewer hospitalizations, stay on the new medication longer, and are less likely to need to use additional antipsychotics. These findings were published today in the American Journal of Psychiatry.

Neurodermatitis genes influence other allergies

There's a typical "career" for some allergic people, and it starts very early on the skin: babies develop atopic dermatitis, food allergies may follow, then comes asthma and later on hay fever. A group of scientists led by Ingo Marenholz and Young-Ae Lee at the Max Delbrück Center for Molecular Medicine in the Helmholtz Association (MDC), working with colleagues from several institutions, has now identified seven genetic risk loci for this course of disease. Two of these loci were previously unknown and mainly influence the connection between atopic dermatitis and asthma. According to the study, the regions that determine the risk for atopic dermatitis are mainly those that also determine the risk for the further development of the typical allergic career. This course of disease is also called the "atopic march."

Cancer treatment in a painless patch

Chemotherapy is a life-saving medical intervention for millions of cancer patients, but the treatment is often not a pleasant experience. To kill off cancer cells, chemotherapy drugs must directly enter the patient's bloodstream and so they are administered intravenously. But are large, often painful needles the only reliable way to deliver the drugs?

Mucus—the first line of defence

By licking a wound it heals faster – this is not simply popular belief, but scientifically proven. Our saliva consists of water and mucus, among other things, and the mucus plays an important role. It stimulates white blood cells to build a good defence against invaders, according to a group of researchers at Lund University in Sweden together with colleagues from Copenhagen and Odense in Denmark.

Young child just as reliable a witness as an adult

The eyewitness account of a young child is no less reliable than that of an adult. Depending on the material 'to be recalled', older children and adults produce more false memories than young children do. Forensic psychologist Henry Otgaar discovered this during his research project 'Shifting Memories: Reversing Developmental Trends in Memory Illusions in (non)Maltreated Populations', which he is carrying out at Maastricht University with financial support from a Veni grant of the Talent Scheme. The article will be published shortly in Journal of Experimental Psychology: General.

Targeted treatment produces rapid shrinkage of recurrent, BRAF-mutant brain tumor

A team led by Massachusetts General Hospital (MGH) investigators has reported the first successful use of a targeted therapy drug to treat a patient with a debilitating, recurrent brain tumor. In a paper published online in the Journal of the National Cancer Institute, the researchers report that treatment with the BRAF inhibitor dabrafinib led to shrinkage of a BRAF-mutant craniopharyngioma that had recurred even after four surgical procedures. More than a year after dabrafinib treatment, which was followed by surgery and radiation therapy, the patient's tumor has not recurred.

The Ebola mobile suitcase laboratory successfully tested in Guinea

An international team of researchers, including Ahmed Abd El Wahed, scientist at the University of Göttingen and the German Primate Center, has tested a new method for rapid diagnosis of Ebola in a field trial in Guinea. The test procedure was carried out using a portable suitcase laboratory. The mobile suitcase lab is operated with solar power and enables simple on-site diagnostics in remote areas without the need of an equipped laboratory. The new detection method, a recombinase polymerase amplification technique, shortly RPA, is based on the rapid identification of viral RNA in oral swabs of infected persons at 42 degrees. The comparison with two other currently available diagnostic methods revealed that the RPA is a very sensitive and rapid technique. An Ebola infection case was detected after 30 minutes. The results of the field study have been published in the current issue of the journal Eurosurveillance.
