The October issue of GIE: Gastrointestinal Endoscopy features several new studies evaluating various treatments for Barrett's esophagus (BE).

Astronomers use IAC instrument to probe the origins of cosmic rays
In November 1572 a supernova explosion was observed in the direction of the constellation of Cassiopeia, and its most famous observer was Tycho Brahe, one of the founders of modern observational astronomy.

Sensitivity to time improves performance at remotely controlling devices
A new study finds that people who are more sensitive to the passage of time are better at accounting for the latency -- or time lag -- inherent in remotely controlling robots or other tools.

Cannabis consumption increases violent behaviour in young people in psychiatric care
A new study on cannabis use that involved 1,136 patients (from 18 to 40 years of age) with mental illnesses who had been seen five times during the year after discharge from a psychiatric hospital demonstrates that sustained used of cannabis is associated with an increase in violent behaviour in young people.

The World-record 53.3 Tb/s optical switching capacity for data-center networks
NICT has successfully demonstrated a world-record for switching capacity of 53.3 Tb/s for short-reach data-center networks.

Energy against the current on a quantum scale, without contradicting the laws of physics
In a classical thermodynamic system, the heat current flows from the hotter body to the colder one, or electricity from the higher voltage to the lower one.

'Lost chapel' of Westminster Palace revealed in new 3-D model
The first dedicated House of Commons chamber, destroyed in the 1834 Palace of Westminster fire, has been reconstructed with the help of 3-D visualization technology.

Researchers help develop new antifungal drug
University researchers, working with F2G Limited (Eccles, Manchester), have developed a new antifungal drug to help in the treatment of life threatening invasive fungal infections such as invasive aspergillosis.

NASA analyzes Tropical Storm Nate
NASA's Aqua satellite and NOAA's GOES East satellite provided imagery of Tropical Storm Nate affecting Nicaragua and extending into the Caribbean Sea.

Antibiotics for dental procedures linked to superbug infection, study shows
Dental procedures are an overlooked source of antibiotic prescribing, which is a concern as these medications increase the risk of developing C. difficile, according to an IDWeek study.

New telescope attachment allows ground-based observations of new worlds
A new, low-cost attachment to telescopes allows previously unachievable precision in ground-based observations of planets beyond our solar system.

What can be discovered at the junction of physics and chemistry?
TSU scientist Rashid Valiev and colleagues from the universities of Helsinki and Oslo have discovered a new type of rare molecules whose properties can be controlled by changing the induction of an external magnetic field.

DNA damage caused by cancer treatment reversed by ZATT protein
An international team led by scientists at the National Institutes of Health is the first to discover a new way that cells fix an important and dangerous type of DNA damage known as a DNA-protein cross-link (DPC).

New York City PrEP prescriptions increase nearly 1,000 percent, but disparities remain
New York City saw a 976 percent increase in PrEP prescriptions in two years, but disparities remain, according to an IDWeek study.

Tests with topical treatment strategy for fighting skin cancer yield positive results
The methodology developed in Brazil combines low-intensity electric current with a formulation containing nanoencapsulated chemotherapy.

Breakthrough in direct activation of CO2 and CH4 into liquid fuels and chemicals
Researchers from the University of Liverpool have made a significant breakthrough in the direct conversion of carbon dioxide (CO2) and methane (CH4) into liquid fuels and chemicals which could help industry to reduce greenhouse gas emissions whilst producing valuable chemical feedstocks.

Plant cells survive but stop dividing upon DNA damage
The cell cycle is how a cell passes its DNA but ceases if the DNA is damaged, as otherwise it risks passing this damage to daughter cells.

Lifestyle changes can close regional obesity gap, study finds
Lifestyle differences are to blame for regional variation in obesity rates in Scotland, research from the University of Edinburgh has found.

New study analyzes volcanic fatalities in more detail than ever before
Building on existing information and databases relating to volcanic fatalities, scientists from the University of Bristol have, for the first time, been able to classify victims by activity or occupation and look at the distance of their death from the volcano.

Research may lead to improvements in water use for crop irrigation
Two papers published in Irrigation and Drainage may help improve estimates of water requirements for crops, which will save water and minimize losses, allowing more land to be irrigated and subsequently more food to be produced.

Predicting insect feeding preferences after deforestation
Understanding how parasitoids and hosts interact, and how their interactions change with human influence, is critically important to understanding ecosystems.

Cleveland Clinic researchers find link between bacterial imbalances and breast cancer
In a newly published study, Cleveland Clinic researchers have uncovered differences in the bacterial composition of breast tissue of healthy women vs. women with breast cancer.
