Canada's Conservative government said it is suspending visa applications for residents and nationals of countries with "widespread and persistent-intense transmission" of the Ebola virus.

With Friday's decision, Canada joined Australia in suspending entry visas for people from Ebola-stricken countries in West Africa in an attempt to keep the deadly disease away.

She is 44 and single, but journalist Sarah still dreams of having a child, while TV producer Susanah, 38, is waiting for her younger boyfriend to be ready.

To keep their hopes alive, these New York women have spent tens of thousands of dollars on freezing their eggs in a practice that has become increasingly popular.

A $500 million lawsuit against Kimberly-Clark Corp. alleges the company falsely claimed its surgical gowns protected against Ebola and other infectious diseases.

The suit, filed Wednesday in federal court, alleges that the multinational company knew for at least a year that its Microcool Breathable High Performance Surgical Gown had failed industry tests of impermeability to blood and microbes, but it continued to claim the product provided the highest level of protection against diseases including Ebola.

The Ebola virus is often deadly, but not always, and a study on mice Thursday suggested that genetics may play a role in the severity of the illness.

At a high-security, state-of-the-art biocontainment laboratory in Hamilton, Montana, scientists infected mice with a mouse form of the same species of the Ebola virus that is sweeping West Africa.

Marijuana shops have sprouted across Denver ever since Colorado legalized the drug for adults in January, but the popularity of pot-infused edibles has surprised authorities, and parents are seeking a ban ahead of Halloween.

Many here are content taking the traditional approach -- lighting up a joint -- to embrace the Rocky Mountain state's marijuana legalization.

After weeks of Ebola panic, false alarms and quibbles over quarantine in the United States, health authorities are bracing for a new battle: flu season.

The end of October marks the start of influenza season, bringing with it the predictable sniffles, sneezes, fever and aches that can extend well into the spring months.

A Google project to develop nanoparticles that can detect cancer cells inside the body is a useful contribution but faces important hurdles, experts said on Wednesday.

The technology could yield "another tool in our arsenal (but) in my opinion, it won't be a game-changer in terms of diagnostics," said Agnes Buzyn, president of France's National Cancer Institute (InCA).

One of the widest investigations into autism has implicated several dozen genes, boosting the search for a diagnostic tool and new treatments, scientists said on Wednesday.

Mutations in these genes emerged in two studies which compared thousands of people with autism spectrum disorder against family members with or without ASD.

Scientists using stem cells said on Wednesday they had built the world's first "mini-stomachs" -- tiny clusters of human gastric tissue that could spur research into cancer, ulcers and diabetes.

Called gastric organoids, the lab-dish tissue comprises buds of cells that are "a miniature version of the stomach", the researchers said.

The rate of new Ebola infections appears to be slowing in hard-hit Liberia, but the crisis is far from over, according to the World Health Organization.

"It appears that the trend is real in Liberia and there may indeed be a slowing of the epidemic there," WHO assistant director-general Bruce Aylward told reporters in Geneva.
