  • Want to avoid climate-related disasters? Try moving

    For decades, the response to flooding and hurricanes was a vow to rebuild. A.R. Siders believes the time has come to consider managed retreat, or the practice of moving communities away from disaster-prone areas to safer lands.

  • Clever crows

    A new paper, co-authored by Dakota McCoy, a graduate student working in the lab of George Putnam Professor of Biology David Haig, suggests that, after using tools, crows were more optimistic.

  • Prospects clouded for finding life on the largest class of planets

    Led by Laura Kreidberg, a Clay Fellow at the Harvard-Smithsonian Center for Astrophysics, a new study shows that LHS 3844b, a terrestrial exoplanet orbiting a small sun 48.6 light-years away, has no detectable atmosphere

  • How the moon came to be

    A fourth-year graduate student in the lab of Professor of Geochemistry Stein Jacobsen, Yaray Ku is working on a project aimed at understanding how the moon formed, and to do it, she’s working with actual lunar samples.

  • Mercury levels in fish are on the rise

    A new study concludes that while the regulation of mercury emissions have successfully reduced methylmercury levels in fish, spiking temperatures are driving those levels back up and will play a major role in the methylmercury levels of marine life in the future.

  • Giving teachers a DNA refresher

    Mansi Srivastava’s lab worked with middle school teachers in an education workshop on DNA and evolution.

  • The Mesoamerican attraction to magnetism

    Led by Assistant Professor of Earth and Planetary Sciences Roger Fu, a team of researchers has shown that the makers of ancient Mesoamerican statues found in Guatemala intentionally carved the figures to place the magnetic areas over the navel or right temple — suggesting not only that they were familiar with the concept of magnetism, but had some way of detecting the magnetic anomalies.

  • Electrifying insights into how bodies form

    A researcher is reviving the study of bioelectricity to learn how cells communicate with each other to form tissues and organs, and how harnessing those signals could one day lead to truly regenerative medicine, in which amputees could simply regrow limbs.

  • Visual forensics that can detect fake text

    Researchers at the SEAS and IBM Research developed a better way to help people detect AI-generated text.

  • Using body heat to speed healing

    To speeding up wound healing, researchers have developed active adhesive dressings based on heat-responsive hydrogels that are mechanically active, stretchy, tough, highly adhesive, and antimicrobial.

  • A new spin on an old question

    Understanding how DNA and proteins interact — or fail to — could help answer fundamental biological questions about human health and disease.

  • A way to make Mars habitable

    Researchers from Harvard University, NASA’s Jet Propulsion Lab, and the University of Edinburgh suggest that regions of the Martian surface could be made habitable with a material — silica aerogel — that would mimic Earth’s atmospheric greenhouse effect.

  • Solving a statistical nightmare

    Researchers have discovered why the North Atlantic and Northeast Pacific appeared to warm twice as much as the global average, while the Northwest Pacific cooled over several decades.

  • A product idea with legs

    Dakota McCoy, in collaboration with David Haig, led a group of researchers at Harvard studying the black spider and its ultrablack coat with microlenses that could lead to innovations in solar panels and sunglasses glare.

  • Spreading seeds of life

    Scientists at the Institute for Theory and Computation have made a comprehensive calculation suggesting that panspermia could happen, and have found that as many as 10 trillion asteroid-sized objects might exist that carry life.

  • So you think he can dance?

    Snowball the dancing cockatoo is the subject of a study by Radcliffe fellow and Tufts neuroscientist Ani Patel, who suggests the bird’s ability to move in time to music is connected to the way humans groove to a beat.

  • Single letter speaks volumes

    Scientists have used an optimized version of the CRISPR-Cas9 gene-editing system to prevent hearing loss in so-called Beethoven mice, which carry a genetic mutation that causes profound hearing loss in humans and mice alike.

  • Combing out a tangled problem

    A new technique speeds creation of nanowire devices, boosting research into what’s happening inside cells.
