Chestnut Hill, MA (5/3/2021) -- The billion-year-old fossil of an organism, exquisitely preserved in the Scottish Highlands, reveals features of multicellularity nearly 400 million years before the biological trait emerged in the first animals, according to a new report in the journal Current Biology by an international team of researchers, including Boston College paleobotanist Paul K. Strother.
People have become accustomed to having their temperature checked during the pandemic because fever is a key indicator of COVID-19.
A new commentary by Washington State University College of Nursing Associate Professor Catherine Van Son and Clinical Assistant Professor Deborah Eti proposes that taking a temperature is a less useful indicator of infection in older adults and that a pulse oximeter be used instead.
Palo Alto, CA--New work from a Stanford University-led team of researchers including Carnegie's Arthur Grossman and Tingting Xiang unravels a longstanding mystery about the relationship between form and function in the genetic material of a diverse group of algae called dinoflagellates.
Their findings, published in Nature Genetics, have implications for understanding genomic organizational principles of all organisms.
CHAMPAIGN, Ill. --A new study found overlooked tsunami hazards related to undersea, near-shore strike-slip faults, especially for coastal cities adjacent to faults that traverse inland bays. Several areas around the world may fall into this category, including the San Francisco Bay area, Izmit Bay in Turkey and the Gulf of Al-Aqaba in Egypt.
ALBUQUERQUE, N.M. -- Sometime between 50,000 and 70,000 years ago, prehistoric humans took their first steps into Sahul, an ancient landmass made up of modern Australia, New Guinea and Tasmania. But nobody knows which way they went after that.
"One of the really big unanswered questions of prehistory is how Australia was populated in the distant past. Scholars have debated it for at least 150 years," said Sandia National Laboratories archaeologist and remote sensing scientist Devin White.
A year into the COVID-19 pandemic, mass vaccinations have begun to raise the tantalizing prospect of herd immunity that eventually curtails or halts the spread of SARS-CoV-2. But what if herd immunity is never fully achieved - or if the mutating virus gives rise to hyper-virulent variants that diminish the benefits of vaccination?
Those questions underscore the need for effective treatments for people who continue to fall ill with the coronavirus. While a few existing drugs show some benefit, there's a pressing need to find new therapeutics.
An abnormal build up of carbohydrates -- sugars and starches -- in the kernels and leaves of a mutant line of corn can be traced to one misregulated gene, and that discovery offers clues about how the plant deals with stress.

Using social values for profit cheapens them, a new study cautions.
Toronto - Businesses sometimes align themselves with important values such as a clean environment, feminism, or racial justice, thinking it's a win-win: the value gets boosted along with the company's bottom line.
But be careful, warns new research from the University of Toronto's Rotman School of Management.
Using these values primarily for self-interested purposes such as profit or reputation can ultimately undermine their special status and erode people's commitment to them.
TORONTO - Scientists at the Krembil Brain Institute, part of University Health Network (UHN), in collaboration with colleagues at the Centre for Addiction and Mental Health (CAMH), have used precious and rare access to live human cortical tissue to identify functionally important features that make human neurons unique.
This experimental work is among the first of its kind on live human neurons and one of the largest studies of the diversity of human cortical pyramidal cells to date.
LUGANO, Switzerland, 3 May 2021 - As breast cancer becomes a largely curable disease, with more than 70% of women surviving at least 10 years after diagnosis across most of Europe thanks to early detection and treatment, (1) the quality of life after cancer has become an important aspect of the patient journey - one that may be inadequately addressed with current standards of follow-up.
A research team from the Institut de Neurociències at the Universitat Autònoma de Barcelona (INc-UAB) has showed that inhibition through a drug of the Tac2 neuronal circuit, involved in the formation of the memory of fear, has opposite effects on the ability to remember aversive events in mice according to sex: it is reduced in male mice and increased in female mice.
Boston, MA (May 2, 2021) - A new study, presented today at the AATS 101st Annual Meeting, finds that AATS Foundation fellowships support success in academic surgery career tracks. The AATS Foundation has two primary grant funding mechanisms: the AATS Foundation Scholarship and the Surgical Investigator Award. The study looked at publications, citations, NIH funding, and leadership position of awardees, among other factors.
Boston, MA (May 2, 2021) - A new study, presented today at the AATS 101st Annual Meeting, found that heart transplantation using donation after cardiac death (DCD) with normothermic regional perfusion (NRP) is feasible in the United States. Broader application of DCD heart transplantation has the potential to increase cardiac allograft availability by 20-30 percent.
Diatoms are tiny unicellular plants -- no bigger than half a millimeter -- which inhabit the surface water of the world's oceans where sunlight penetration is plenty. Despite their modest size, they are one of the world's most powerful resources for removing carbon dioxide (CO2) from the atmosphere. They currently remove, or "fix," 10-20 billion metric tons of CO2 every year by the process of photosynthesis.
The legacy of systemic racism in the U.S impacts psychosis risk at the individual and neighborhood level, according to a definitive review published online today. Researchers examined U.S. based evidence connecting social and environmental factors with outcomes relating to psychotic experiences, including schizophrenia.
