One of the strongest indicators that a planet could harbor life is if a planet’s … Continue reading TRAPPIST-1 and Earth’s distant cousins

Spectrum

These colorful fractions were obtained upon purifying a synthetic small-molecule through flash column chromatography. Though most of these were impurities (bright colors in organic chemistry is usually not a great sign), it served as a reminder to appreciate the beauty in the mundane and seemingly unimportant. Contributed by Carmen Sivakumaren, a graduate student in the Biological and Biomedical Sciences Program at Harvard Medical School.   Continue reading Spectrum

The wait is sometimes years long, despite many of the candidates being in critical condition. But what if the need for transplant waiting lists could be eliminated? Recent advances in a decades-old technology known as chimerism give reason to believe that this … Continue reading The End of the Waitlist: How chimeras could solve the organ transplant problem

One Neuron to Rule Them All?

  The brain is arguably the most complex organ in the human body and understanding its structure could help explain a fundamental mystery of human existence: consciousness. The brain is composed of billions of specialized cells called neurons, which communicate with each other via electrical and chemical signals. Neurons are responsible for processes ranging from vital life functions to the ability to walk, talk remember, … Continue reading One Neuron to Rule Them All?
