Tweezers untangle chemotherapeutic’s impact on DNA

Newswise — ITHACA, NY — New Cornell research is providing a fresh view into the ways a common chemotherapy agent, etoposide, stalls and poisons the essential enzymes that allow cancer cells to flourish. The findings, from the lab of Michelle Wang, the James Gilbert White Distinguished Professor of the Physical Sciences and Howard Hughes Medical … Read more

COVID calculations lead to an unexpected solution to a long-standing problem in theoretical computer science

Newswise — At the beginning of the COVID-19 pandemic, Joachim Kock, mathematician at the Universitat Autònoma de Barcelona (UAB), began to experiment with epidemiological models. He did not improve upon the predictions, but unexpectedly he made a mathematical discovery that led to the solution of an old problem in theoretical computer science, open since the … Read more

Corona vaccine based on new technology tested in clinical study

Newswise — A new COVID-19 vaccine based on a different platform than current vaccines on the market has been tested in humans for the first time by researchers at Radboud University Medical Center. Administration of this vaccine in healthy study participants was well tolerated and led to a good immune response. The effectiveness of the … Read more

The Mechanism Of Cosmic Magnetic Fields Explored in the Laboratory

The Science Plasma is matter that is so hot that the electrons are separated from atoms. The electrons float freely and the atoms become ions. This creates an ionized gas—plasma—that makes up almost all of the visible universe. Recent research shows that magnetic fields can spontaneously emerge in a plasma. This can happen if the … Read more

Using fungi, researchers convert ocean plastic into ingredients for the drug industry

Newswise — LAWRENCE — Research on fungi underway at the University of Kansas has helped transform tough-to-recycle plastic waste from the Pacific Ocean into key components for making pharmaceuticals. The chemical–biological approach for converting polyethylene uses an everyday soil fungus called Aspergillus nidulans that has been genetically altered. The results were reported recently in the … Read more

New research identifies a potential treatment target for hepatoblastoma, the most common liver cancer in children

Newswise — Philadelphia, January 16, 2023 – Although rare compared to adult liver cancers, hepatoblastoma is the most common pediatric liver malignancy, and its incidence is increasing. In this novel study appearing in The American Journal of Pathologypublished by Elsevier, investigators studying a mouse model of hepatoblastoma report that the protein heat shock transcription factor … Read more

Hubble Finds Hungry Black Hole Twisting Captured Star Into Donut Shape

FOR RELEASE: 5:15 pm (EST) January 12, 2023 RELEASE: STScI-PR2023-001 Newswise — Black holes are gatherers, not hunters. They lie in wait until a hapless star wanders by. When the star gets close enough, the black hole’s gravitational grasp violently rips it apart and sloppily devours its gases while belching out intense radiation. Astronomers using … Read more

New Generator Rolls into Ocean Energy

Newswise — Tsunamis, hurricanes, and maritime weather are monitored using sensors and other devices on platforms in the ocean to help keep coastal communities safe—until the batteries on these platforms run out of juice. Without power, ocean sensors can’t collect critical wave and weather data, which results in safety concerns for coastal communities that rely … Read more

Eavesdropping on the Earth itself

Newswise — The more-than 1.2 million km of fiber-optic cables that criss-cross the planet carry the world’s phone calls, internet signals and data. But this summer, researchers published the eerie sounds of blue and fin whales detected by a fiber-optic cable on the west coast of Svalbard — a first. Now the researchers want to … Read more

LJI scientists solve the mystery of why OGT enzyme is critical for cell survival

Newswise — LA JOLLA, CA — Researchers at the La Jolla Institute for Immunology (LJI) have finally uncovered how an enzyme called O-GlcNAc transferase (OGT) keeps cells healthy. Their findings, published in the Proceedings of the National Academies of Sciencesreveals a key aspect of cellular biology and may lead to important medical advances. “Many diseases … Read more
