NASA telescope finds its first Earth-sized habitable world
TOI 700 d is the first Earth-size habitable-zone world discovered by TESS. Astronomers have discovered an Earth-sized planet living in its star’s “habitable zone” — a range of distances where conditions allow…
Ultrasound therapy improves the memory of Alzheimer’s patients
In a small group of patients, language and memory showed improvement for up to 3 months after ultrasound brain stimulation therapy. Brain stimulation therapies have emerged as viable tools to treat a…
Pioneers in Science: Sir Frederick Banting
A doctor and researcher, Banting pioneered the development of insulin for the treatment of diabetes. Illustration: Kieran O’Brien Sir Frederick Banting was a Canadian physician and scientist who gained global acclaim and…
The first CRISPR gene therapy to cure sickle-cell disease
In 2019, CRISPR gene-editing therapy was used for the first time to treat sickle cell disease. Sickle cell disease is a complex disease that affects the structure and function of hemoglobin, the…
A Switchable Catalyst Based on a Molecular Motor
The first switchable catalyst for asymmetric catalysis based on a molecular motor. In chemistry, chirality refers to a molecule that exists in two forms that are mirror images to one another—much like…
Astronomers Cast Doubt on the Cosmological Principle
Recent studies incorporating gamma-ray bursts have yielded interesting new results that cast doubt on the validity of the cosmological principle. The big bang theory is based on two assumptions: the first is…
Automating the Production of Advanced Materials
Engineers create a robotic platform to automate the production of new, functional polymers for advanced materials. The robotic revolution is accelerating as the capabilities of robots expand, leading us toward a more…
Philae Marks the First Ever Soft Landing on a Comet
In 2014, scientists achieved the first ever soft landing on a comet, forever pushing the boundaries of space exploration. On November 14, 2014, the Philae lander accomplished the first ever soft landing…
Study Reveals Hepatitis A Originated in Insects
Unraveling the mystery of viral evolution, scientists discover a similarity between hepatitis A and the Triatoma virus that infects blood-sucking kissing bugs. Hepatitis viruses are major threats to human health, resulting in…
