Say hello to Scotty, the oldest and biggest T. rex ever found Scotty’s unearthed fossils reveals a fairly complete set of bones including a hips, limbs, and a complete skull, allowing scientists to get better measurements than ever before.

The one of the largest land predators to have ever lived, the mighty Tyrannosaurus rex, just crowned a new king. On March 21st, a team of University of Alberta scientists described the oldest and largest T. rex ever found. Scotty’s unearthed fossils reveals a fairly complete set of bones including a hips, limbs, and a complete skull, but for a complete, set paleontologists still had to use what they knew about T. rex anatomy to fill in the blanks.

New Sex Chromosomes Created After Decades Long Experiment Hybrid swordtail fish may reveal secrets about how new chromosomes and species form

Sexually reproducing animals have their sex determined through many mechanisms. Sex in reptiles such as alligators is determined by egg temperature during incubation. Some species, like the clownfish, can be hermaphroditic, shifting from one gender to another depending on the environmental READ MORE

We must go deeper: Submerging net cages for healthier fish Submerging fish farms may be better for fish, but how can it be done for fish that also need air?

Most fish farming in the ocean uses net cages that float because it is easier to feed and remove fish at the surface and because some fish species require access to air. However, the surface of the ocean experiences a READ MORE

When it comes to buying seafood, there are five kinds of people. Which one are you? Consumers are becoming more conscious than ever about their food, and companies are following their lead by finding out what matters to them.

What makes a person choose a certain kind of fish when shopping at the grocery store? A group of German researchers surveyed shoppers to better understand their buying decisions. This makes it easier for aquaculture farmers to be profitable and consumers to be satisfied.

Bulking Up: Increasing Muscle Mass in Fish with Gene Editing Researchers increase the amount of edible flesh in red sea bream by editing the gene for a hormone that restricts muscle growth

There may be concerns with genetically modified organisms (GMO), but the effectiveness of gene editing in developing more productive plants and animals for the agriculture industry can not be argued. With the rise of cheap and simple gene editing technologies, READ MORE

Cave Bears Probably Did Eat Their Vegetables Isotope analysis indicates that the prehistoric cave bear diet was much more reliant on plants than previously thought

Modern bears, while typically thought of as carnivores, actually have a wide variety of dietary preferences. Some eat only meat while others are omnivores, meaning that they eat both meat and vegetation. Cave bears (Ursus spelaeus), an extinct bear species READ MORE

Food or Foul? Aquaculture Pests May Actually be a Valuable Resource. Small invertebrates that grow around fish farms may provide a sustainable and nutritious food source

Many marine organisms have a planktonic form. This means that they drift in the ocean for part of their life until they can find something suitable to attach to and grow. A common example of an animal like this would READ MORE

Why Could Tyrannosaurus rex Bite So Hard? Modeling the bite force of T. rex helps to explain important dietary clues about the animal.

Be grateful you didn’t live at the same time as a T-rex, because it’s superior biting strength could really mess you up. Scientists at Oklahoma State and Florida State collaborate to understand why that is.
