Using CRISPR to create different sets of mutations in a gene promoter called SICLV3 (and in several other promoters) enabled researchers to vary the number of floral organs and locules (gelatinous seed compartments) in tomato, over a wide range. The effect is analogous to turning a dimmer switch to vary light levels over a continuous

During cell division, parent cell chromosomes and their duplicates sort themselves out by condensing, becoming thousands of

This figure shows the risk that freshwater fish (top) and marine fish (bottom) could exceed their thermal limits by the year 2070. Blue indicates a low risk and red shows a high risk.

This infographic represents the roadmaps developed by Jacobson et al for 139 countries to use 100 percent wind-water-solar in all energy sectors by 2050. Credit: The Solutions Project The latest roadmap to a 100% renewable energy future from Stanford’s Mark Z. Jacobson and 26 colleagues is the most specific global vision yet, outlining infrastructure changes

This is methane gas leakage near a well. Credit: ROV KIEL6000, GEOMAR The pictures went around the world. In April 2010, huge amounts of methane gas escaped from a well below the Deepwater Horizon platform in the Gulf of Mexico. This “blow-out” caused an explosion, in which eleven people died. For several weeks, oil spilled

An artist’s depiction of the promise of carbon nanotube porins for desalination. The image depicts a stylized carbon nanotube pipe that delivers clean desalinated water from the ocean to a kitchen tap.

The black hole named Cygnus X-1 formed when a large star caved in. This black hole pulls matter from the blue star beside it.

Fish are expected to shrink dramatically in warmer waters. Credit: Lindsay Lafreniere Fish are expected to shrink in size by 20 to 30 per cent if ocean temperatures continue to climb due to climate change. A new study by researchers at the University of British Columbia provides a deeper explanation of why fish are expected

This is a driver inside the car. The inset shows his eye movement. Credit: Otto Lappi All drivers know from personal experience that they must keep their eyes on the road when driving through curves. But how exactly does looking at the road guide the car through the curve? Cognitive scientist Otto Lappi’s dissertation at
