(Press-News.org) WASHINGTON, May 27, 2014 — We all know bacon is delicious, but what is it about cooking bacon that makes it smell so tantalizing? In the American Chemical Society's (ACS') latest Reactions video, the team puts its nose into everyone's favorite breakfast food. We collaborated with the Compound Interest blog to break down the science of that sweet smell. The video is available at http://youtu.be/2P_0HGRWgXw

Scientists map the worst times of day for people allergic to grass pollen
Atishoo! Help, there are flowering grasses around, please stay indoors – while your friends enjoy the nice summer weather! Traditionally, people allergic to grass pollen are advised to be aware of high pollen concentrations during the day, and to reduce their outdoor activities during this period. A new study led by researchers from Aarhus University shows that it is considerably more complicated to avoid grass pollen. Based on a three-year study with intensive measurements at three different locations in Aarhus, they divide the grass pollen season into three periods, ...
Sperm cells are extremely efficient at swimming against a current
Like salmon traveling upstream to spawn, sperm cells are extremely efficient at swimming against the current, according to research to be published this week. The discovery, to be published in the journal eLife by researchers at MIT and Cambridge University, may help us to understand how some sperm travel such long distances, through difficult terrain, to reach and fertilize an egg. Of the hundreds of millions of sperm cells that begin the journey up the oviducts, only a few hardy travelers will ever reach their destination. Not only do the cells have to swim in the ...
Attack is not always the best defense
Jena (Germany) It is something like the police force of our body: the immune system. It disables intruding pathogens, it dismantles injured tissue and boosts wound healing. In this form of 'self-defense' inflammatory reactions play a decisive role. But sometimes the body's defense mechanism gets out of control and cells or tissues are affected: "Then excessive reactions can occur and illnesses along with them," Prof. Dr. Oliver Werz of the Friedrich Schiller University Jena says. He gives asthma, rheumatism, arteriosclerosis and cancer as examples: "For many of these diseases ...
The secret cargo of mosquitoes
The parasite Dirofilaria repens is a roundworm that primarily attacks the subcutaneous tissue of dogs and causes lumps in the skin, swelling, and itching. Dogs, cats, foxes, wolves and martens can be infected in addition to dogs. "In humans, 16 cases of human dirofilariosis have been recorded since the year 2000, but the dark figure is definitely higher", says the lead author Katja Silbermayr. Humans, however, are so-called dead end hosts; the parasite does not reproduce in humans and therefore poses no major risk. Silbermayr is a veterinarian and performs research on ...
Seeing e-cigarette use encourages young adult tobacco users to light up
VIDEO: "Whether participants were exposed to someone smoking a combustible or an e-cigarette, the urge to smoke a combustible cigarette was just as high in either condition, " King said. "If the... Click here for more information. Seeing people use electronic cigarettes (e-cigarettes) increases the urge to smoke among regular combustible cigarettes users, according to a new study of young adult smokers. This elevated desire is as strong as when observing someone ...
Stanford researchers discover immune system's rules of engagement
A study led by researchers at Stanford's School of Medicine reveals how T cells, the immune system's foot soldiers, respond to an enormous number of potential health threats. X-ray studies at the Department of Energy's SLAC National Accelerator Laboratory, combined with Stanford biological studies and computational analysis, revealed remarkable similarities in the structure of binding sites, which allow a given T cell to recognize many different invaders that provoke an immune response. The research demonstrates a faster, more reliable way to identify large numbers ...
Climate change accelerates hybridization between native and invasive species of trout
BOZEMAN, Mont. – Scientists have discovered that the rapid spread of hybridization between a native species and an invasive species of trout in the wild is strongly linked to changes in climate. In the study, stream temperature warming over the past several decades and decreases in spring flow over the same time period contributed to the spread of hybridization between native westslope cutthroat trout and introduced rainbow trout – the world's most widely introduced invasive fish species –across the Flathead River system in Montana and British Columbia, Canada. Experts ...
New perspectives to the design of molecular cages
Researchers from the University of Jyväskylä report a new method of building molecular cages. The method involves the exploitation of intermolecular steric effects to control the outcome of a self-assembly reaction. Molecular cages are composed of organic molecules (ligands) which are bound to metal ions during a self-assembly process. Depending on the prevailing conditions, self-assembly processes urge to maximize the symmetry of the system and thus occupy every required metal binding site. The research group led by docent Manu Lahtinen (University of Jyväskylä, Department ...
Molecules do the triple twist
An international research team led by Academy Professor Kari Rissanen of the University of Jyväskylä (Finland) and Professor Rainer Herges of the University of Kiel (Germany) has managed to make a triple-Möbius annulene, the most twisted fully conjugated molecule to date, as reported in Nature Chemistry (DOI:10.1038/nchem.1955, published online 25 May 2014). An everyday analogue of a single twisted Möbius molecule is a Möbius strip. It can be made easily by twisting one end of a paper strip by 180 degrees and then joining the two ends. A triple twisted Möbius molecule ...
Insights into genetics of cleft lip
Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, have identified how a specific stretch of DNA controls far-off genes to influence the formation of the face. The study, published today in Nature Genetics, helps understand the genetic causes of cleft lip and cleft palate, which are among the most common congenital malformations in humans. "This genomic region ultimately controls genes which determine how to build a face and genes which produce the basic materials needed to execute this plan", says François Spitz from EMBL, who led the work. ...
