Omicron Brings COVID-19 Vaccine Inequity 'Home to Roost'

The emergence of the new omicron variant and the world's desperate and likely futile attempts to keep it at bay are reminders of what scientists have warned for months: The coronavirus will thrive as long as vast parts of the world lack vaccines.

The hoarding of limited COVID-19 shots by rich countries — creating virtual vaccine deserts in many poorer ones — doesn't just mean risk for the parts of the world seeing shortages; it threatens the entire globe.

New Research Offers Glimpse into Early Human Development

Scientists have been able to get a rare glimpse into a crucial, early stage of human development by analyzing an embryo in its third week after fertilization — a moment in time that has been difficult to study because of both practical and ethical considerations.

European researchers looked at a single embryo that was 16 to 19 days old, donated by a woman who ended her pregnancy. Until now, experts said, researchers have lacked a full understanding of this stage of development because human embryos at this stage are difficult to obtain. Most women don't yet know they're pregnant by this point and decades-old global guidelines have until recently prohibited growing human embryos in a lab beyond 14 days.

Why No Tusks? Poaching Tips Scales of Elephant Evolution

A hefty set of tusks is usually an advantage for elephants, allowing them to dig for water, strip bark for food and joust with other elephants. But during episodes of intense ivory poaching, those big incisors become a liability.

Now researchers have pinpointed how years of civil war and poaching in Mozambique have led to a greater proportion of elephants that will never develop tusks.
