Curly—or Karelian—birch is a mysterious tree with a patterned wood texture and a bizarre trunk shape. Unlike the elegant white-stemmed traditional birch, the Karelian one may seem unsightly at first glance: It is a low-growing, sinuous tree with bumps and

Researchers at the University of Toronto and Sinai Health have created a new platform to identify proteins that can be co-opted to control the stability of other proteins—a new but largely unrealized approach to the treatment of disease.

Researchers at McMaster University and Stanford University have invented a new generative artificial intelligence model that can design billions of new antibiotic molecules that are inexpensive and easy to build in the laboratory.

Scaling down single-cell reactions to the nanoliter level is critical to minimize the risk of contamination, increase reaction efficiency, and reduce costs. Researchers from the Single-cell Center of the Qingdao Institute of Bioenergy and Bioprocess Techn

Why is the heart slightly on the left side of the body for most people? Why is DNA almost always a right-handed helix? Same with alpha helices, the building blocks of proteins. Chirality, or handedness, is everywhere in biology, but the reasons can be a m

A new analysis of zooplankton in western Lake Erie shows that their biomass and seasonal behavioral patterns have been drastically altered by human-driven changes in water temperature and food webs.

Arachnophobia can make humans flee at the sight of a brown recluse, black widow or even a daddy long legs, but animal predators of spiders know no such fear.

It's no surprise that your dog can learn to sit when you say "sit" and come when called. But a study appearing March 22 in the journal Current Biology has made the unexpected discovery that dogs generally also know that certain words "stan

The demand for renewable energy sources is constantly growing fueling the development of catalytic-based technologies. By separating and forming chemical bonds, these technologies can be used to produce environmentally friendly energy.

Finding the best method to deliver chemotherapeutic drugs to tumor cells can be tricky. Ideally, the treatments target tumor cells while leaving healthy cells alone.

A newly developed "GPS nanoparticle" injected intravenously can home in on cancer cells to deliver a genetic punch to the protein implicated in tumor growth and spread, according to researchers from Penn State. They tested their approach in huma

Sometimes, seeing clearly requires complete black. For astronomy and precision optics, coating devices in black paint can cut down on stray light, enhancing images and boosting performance. For the most advanced telescopes and optical systems, every littl
