Nearly 43,000 pounds of ground beef recalled due to E. coli
A New Jersey company recalled nearly 43,000 pounds of ground beef that may be contaminated with a strain of E. coli.
How blooms of northern anchovies are helping bring more sea life back to Burrard Inlet
The sight of anchovy scales catching the glint of the sun is becoming more common in B.C. waters, marine biologists say, and that could be drawing other, bigger species back to busy waterways...
A novel mechanism that triggers a cellular immune response
Viruses and other disease-causing microbes influence the type of immune response their hosts will develop against them. In some cases, the predominant response involves antibodies, proteins made by the immune...
Putting ‘Super’ in Natural Killer Cells
Using induced pluripotent stem cells (iPSCs) and deleting a key gene, researchers at University of California San Diego School of Medicine have created natural killer cells — a type of...
Canadian scientist sent deadly viruses to Wuhan lab months before RCMP asked to investigate
One of the scientists escorted from the National Microbiology Lab last year amid an RCMP investigation was responsible for a shipment of Ebola and Henipah viruses to the Wuhan National...
Sugar coating locks and loads coronavirus for infection
They say you can't judge a book by its cover. But the human immune system does just that when it comes to finding and attacking harmful microbes such as the...
Impacts of climate change on migrating mule deer
The benefits of migration are likely to decrease for mule deer and other migratory herbivores as drought becomes more common due to ongoing climate change.
Unlocking PNA's superpowers for self-assembling nanostructures
Researchers have developed a method for self-assembling nanostructures with gamma-modified peptide nucleic acid, a synthetic mimic of DNA. The process has the potential to impact nanomanufacturing and future biomedical technologies...
Water bacteria have a green thumb
A research team has discover new natural products that bacteria in water use to regulate the growth of competing organisms.
Versatile symbionts: Reed beetles benefit from bacterial helpers through all life stages
Researchers have investigated the contributions that symbiotic bacteria make to the unusual life cycle and diet of reed beetles.
Statistical analyses of plant metabolites allow solid testing of plant defense theories
Do plants attacked by herbivores produce substances that are most effective against attackers in a targeted manner, or are herbivore-induced changes in a plant metabolism random, which could thwart the...
An ion channel senses cell swelling and helps cells to choose a response
Researchers provide new insights into how plants sense and respond to mechanical signals, such as cell swelling, rather than chemicals signals, such as nutrients or growth factors.
Some social distancing with your chardonnay? Wineries are reopening across California
Sonoma County wineries are reopening to an altered landscape
TiO₂ nanocrystals exhibit unusual slow-motion blinking
Made via template-based synthesis, the defective crystals actively mediate photocatalysis
Researchers restore neural connections in zebra fish
Harvard University researchers have developed an engineering technique to precisely control the direction that neurons grow their axons, cable-like structures that allow nerve cells to connect with each other. In a zebrafish model,...
Neurons that control hibernation-like behavior are discovered
The dream of suspended animation has long captivated the human imagination, reflected in countless works of mythology and fiction, from King Arthur and Sleeping Beauty to Captain America and Han Solo. By effectively...
Tens of thousands sign petition to keep Disneyland closed until coronavirus outbreak is under control
The online petition urges Disney executives to keep the Disneyland Resort closed until the COVID-19 pandemic abates.
Function of genetic pathway for reproductive fitness in flowering plants
A research collaboration has demonstrated the function of a genetic pathway for anther development, with this pathway proven in 2019 work to be present widely in the flowering plants that...
Adult stem cell study shows fish oil may help with depression
A new study shows that patient-derived adult stem cells can be used to model major depressive disorder and test how a patient may respond to medication and that fish oil,...
Tiger Woods to skip next week's RBC Heritage at Hilton Head
Tiger Woods will not participate in next week's RBC Heritage at Harbour Town Golf Links in Hilton Head, S.C.
Surface disturbance can limit mule deer migration
Researchers used 145 migrations from 56 individual deer to examine disturbance effects at various scales. Results consistently showed that mule deer use of migration corridors steeply declined when surface disturbance...
Protecting eels protects freshwater biodiversity
An international research team has conducted a field survey on two species of eel native to Japan and other organisms that share the same habitat, revealing for the first time...
From bacteria to you: The biological reactions that sustain our rhythms
Methylation and the circadian clock are both conserved mechanisms found in all organisms. Researchers found that inhibiting methylation with a specific compound disrupts the circadian clock in most organisms except...
Dopamine signaling allows neural circuits to generate coordinated behaviors
For a nematode worm, a big lawn of the bacteria that it eats is a great place for it to disperse its eggs so that each hatchling can emerge into...
Plant cell gatekeepers' diversity could be key to better crops
Scientists have shed new light on how the network of gatekeepers that controls the traffic in and out of plant cells works, which they think is key to develop food...
New approach to turning on the heat in energy-burning fat cells
Researchers have discovered a new set of signals that cells send and receive to prompt one type of fat cell to convert fat into heat. The signaling pathway, discovered in...
Parasites and the microbiome
In a study of ethnically diverse people from Cameroon, the presence of a parasite infection was closely linked to the make-up of the gastrointestinal microbiome, according to a research team.
Red pandas tracked by satellite in conservation 'milestone'
Red pandas in Nepal are being monitored in their last stronghold in the mountainous forests of Nepal.
