Engineers have devised an elegantly simple new system to pull greenhouse gas from seawater. No membranes. No chemicals. And a lot less energy required.
In their experiments, 80% of broccoli, lettuce and pak choi seedlings survived on seawater and sunshine—with little human involvement.
By combining key traits of two bacterial species, the team created a novel bug that can break down plastics in salty conditions—at room temperature.
Researchers calculate that protecting just 5% more of the ocean could boost fisheries by as much as 20%.
A cancer-detecting device can be used to identify fish species in just 15 seconds
If coastal cities planted clam beds along the urban edge, they could save millions in nitrogen clean-up costs
Until now, there have been no thorough estimates of the value of kelp forests. When researchers recently tallied it up, the figured they came up with was $500 billion a year.
Now that whaling has been outlawed for decades, populations are beginning to heal—but they face new threats.
