Białowieża Forest in Eastern Poland is one of the last remaining primeval forests in Europe. For the time being. In 2017, the Polish government had 100,000 more trees logged than previously, despite the fact that large areas of the Natural World Heritage site are under strict protection. They did this under the pretense of preventing the bark beetle from spreading further. The motor saws are quiet now after protests from environmental activists, Europe-wide criticism in the media and concerns by the European Commission. The case has been handed to the European Court and the minister of the environment was sacked.

New research suggests that up to 38% of all annual childhood asthma cases in Bradford may be caused by air pollution.

The U.S. should take bold steps to improve measurement, monitoring, and inventories of methane emissions caused by human activities, says a new report from the National Academies of Sciences, Engineering, and Medicine.  Better data on methane—a greenhouse gas that contributes to air pollution and threatens public and worker safety—would help inform decisions related to climate, economics, and human health.

Researchers from the University of Sheffield have discovered that looking at honeybees in a colony in the same way as neurons in a brain could help us better understand the basic mechanisms of human behaviour.

Police detectives analyze isotopes in human hair to find out where a murder victim was born and grew up. Researchers from the Smithsonian Tropical Research Institute in Panama, the University of Florida and the University of Arizona combined clues from carbon, nitrogen, oxygen and strontium isotope analysis discovering the earliest evidence that the Maya raised and traded dogs and other animals, probably for ceremonial use.

Scientists have developed a new technique to examine the effects of chemicals on digestive systems of fish and support research into gut related conditions. It also has potential to reduce the number of animal experiments, in line with the principles of the 3Rs (Reduce, Refine and Replace).

Catalytic converters for cleaning exhaust emissions are more efficient when they use nanoparticles with many edges. This is one of the findings of a study carried out at DESY’s X-ray source PETRA III. A team of scientists from the DESY NanoLab watched live as noxious carbon monoxide (CO) was converted into common carbon dioxide (CO2) on the surface of noble metal nanoparticles like those used in catalytic converters of cars. The scientists are presenting their findings in the journal Physical Review Letters. Their results suggest that having a large number of edges increases the efficiency of catalytic reactions, as the different facets of the nanoparticles are often covered by growing islands of a nano oxide, finally rendering these facets inactive. At the edges, the oxide islands cannot connect, leaving active sites for the catalytic reaction and an efficient oxygen supply.

A new approach to analyzing and designing new ion conductors — a key component of rechargeable batteries — could accelerate the development of high-energy lithium batteries, and possibly other energy storage and delivery devices such as fuel cells, researchers say.

Obesity is a big problem, and UNLV biologist Allen Gibbs has enlisted millions of six-legged volunteers to help him figure out the genetic basis of a plight that affects an increasing number of Americans.

Optical Mammography, or OM, which uses harmless red or infrared light, has been developed for use in conjunction with X-rays for diagnosis or monitoring in cases demanding repeated imaging where high amounts of ionizing radiation should be avoided. At the OSA Biophotonics Congress: Biomedical Optics meeting, held 3-6 April in Hollywood, Florida, USA, researchers from Milan, Italy, will report an advance in instrument development that increases the sensitivity of OM by as much as 1000-fold.
