How bees stay cool on hot summer days

To determine how bees organize to cool their nests, researchers measured temperature, air flow into and out of the nest, and the position and density of bees fanning at the nest entrance.

Tracking pollen with quantum dots

This bee was caught after it visited a flower of which the pollen grains were labelled with quantum dots. Under the microscope one can see where the pollen was placed, and actually determine which insects carry the most pollen from which flower.

Engineered miniature kidneys come of age

Culturing kidney organoids under fluid flow causes endogenous endothelial progenitors to create more mature vascular networks which pervade the whole organoid and interact with epithelial compartments.

Researchers found male squirrels store more food than females, and…

When is a bobcat not a bobcat?

Two UBC Okanagan biologists, who have publicly solicited images of wild cats for their research, have answered that question. Their recently published study explains how...

Using a specially designed camera, researchers at Lund University in Sweden have succeeded for the first time in recreating how birds see colours in...

Scientists find genes with large effects on head and brain size

Children's heads expand steadily to accommodate their growing brains and doctors routinely measure head circumference during the first years of life to assess healthy...

Engineered T cells promote long-term organ transplant acceptance

Organ transplant rejection is a major problem in transplantation medicine. Suppressing the immune system to prevent organ rejection, however, opens the door to life-threatening...

HKUST scientists develop novel method to monitor molecular aggregation

Chiral molecules are defined as molecules that are non-superimposable on their mirror image, much like that of left and right human hand bone structure....

The algae’s third eye

Just like land plants, algae use sunlight as an energy source. Many green algae actively move in the water; they can approach the light...

Chirality in ‘real-time’

In nature, certain molecules with the same chemical composition, can exist in two different shapes that are mirrors images of each other, much like...

Watching Whales from Space

Scientists have used detailed high-resolution satellite images provided by Maxar Technologies' DigitalGlobe, to detect, count and describe four different species of whales. Reported this...

New Advances in the Fight Against Cancer

Research into cancer can provide new insight into how this disease works and how it can be stopped. The Experimental Biology 2018 meeting (EB...

Improved Healing of Wounds for Diabetics

One of the most frustrating and debilitating complications of diabetes is the development of wounds on the foot or lower leg. Once they form,...
