Prolonged exposure to air pollution can be linked to an increased risk of stroke and coronary heart disease, even when levels are below the limits specified by the EU and WHO, according to a large European study. «Our results indicate that the current air quality guidelines do not provide sufficient protection,» says Petter Ljungman, associate…

POSTECH professor Junsuk Rho’s research team demonstrates artificial control of elastic waves and underwater sounds applicable as stealth technology. Professor Junsuk Rho of POSTECH’s departments of mechanical engineering and chemical engineering and Ph.D. candidate Dongwoo Lee of the Department of Mechanical Engineering in collaboration with Professor Jensen Li of HKUST have designed an artificial structure…

The English Channel prevents many rockpool species ‘making the jump’ from Europe to the UK, new research shows. With sea temperatures expected to rise due to climate change, many rockpool species in south-west England are threatened. Creatures from warmer waters to the south could replace them — but the study, by the University of Exeter,…

Kochia is a highly invasive weed that is common in the Great Plains, where it has developed resistance to multiple herbicides. Now new dicamba-resistant strains are adding to grower worries. In a study featured in the latest edition of the journal Weed Technology, researchers explored two recently discovered dicamba-resistant kochia populations found in fallow fields…

As coral reefs face increasing threats around the world, a team of researchers has developed a genetic analysis tool that can determine many different types of coral on a reef with just a sample of seawater. «Coral reefs are very important,» explained Dr. Koki Nishitsuji, staff scientist in the Marine Genomics Unit at OIST. «Not…

A new study suggests that persistent exposure to air pollutants in residential communities can impact health outcomes for COVID-19 patients. The finding adds to our understanding about environmental factors that increase the risks of COVID-19. The researchers noted that chronic air pollution exposure can alter the pulmonary immune system, may increase systemic inflammation, and can…

Hydrocarbons, which are an essential component of crude oil and natural gas, form under pressure and high temperatures in the deep ocean floor. In the Guaymas Basin in the Gulf of California, researchers have detected hydrocarbon gas patterns that could not have been generated by known formation pathways. In their study they describe a new…

A study has found an association between air pollution and higher levels of deposition of beta-amyloid protein in the brain and of neurofilament light (NfL) in cerebrospinal fluid. «In line with those of other recent studies, our findings indicate that the tiny suspended particles and gases in air pollution, produced primarily by road traffic, may…

Scientists provide an insightful review of how US dairy industry breeding selection objectives are established, as well as detail opportunities and obstacles related to new technologies for documenting animal performance. Genetic selection has been an extremely efficacious tool for the long-term enhancement of livestock populations, and the implementation of genomic selection has doubled the rate…

While the onion, garlic, scallion, shallot and chives have been on our plates for centuries, becoming staple foods around the world, their group, the genus Allium, seems to be a long way from running out of surprises. Recently, a group of researchers from India described a new onion species from the western Himalaya region, long…
