Authors in biomedical journals frequently describe cited evidence as “recent,” yet the actual age of the references behind these phrases has rarely been measured.  To measure how recent the "recent" studies really are, researchers based in Spain analysed 1000 biomedical articles containing 20 predefined “recent” expressions directly linked to a citation.  Their findings in the Christmas issue of The BMJ show that the citation lag ranged from 0 to 37 years, with a median of 4 years and a mean of 5.5 years.   The most frequent ...

A single-dose oral medication called zoliflodacin shows promise as a new treatment for antibiotic-resistant gonorrhoea, according to a phase 3 clinical trial published in The Lancet. The study found that one dose of zoliflodacin was as effective as the current standard treatment, which combines two antibiotics: an injection of ceftriaxone followed by an oral dose of azithromycin. Gonorrhoea is one of the most common sexually transmitted infections, affecting over 82 million people globally each year. However, it is increasingly difficult to treat as the bacteria that cause ...

A blood biomarker yet to be used in cardiac arrest care can give a clearer picture of the extent of brain damage after a cardiac arrest. This has been shown in a large international multicentre study led by researchers at Lund University that has been published in The Lancet Respiratory Medicine. Worldwide, around four million people each year suffer a sudden cardiac arrest “This will transform care for these patients,” says researcher Marion Moseby Knappe. Key facts about the study: clinical prospective multicentre study // 819 patients // out-of- hospital cardiac arrest // A simple blood test that can very accurately predict the chance of survival with good recovery ...

A new UBC Okanagan study found that people who microdose psychedelics feel better on the days they take them—but those boosts don’t seem to last. This suggests, says Dr. Michelle St. Pierre, that perceived benefits may be acute rather than long lasting. Dr. St. Pierre is a post-doctoral psychology researcher with UBCO’s Irving K. Barber Faculty of Arts and Sciences. She recently published a study in Psychopharmacology that tracks the daily experiences of people who microdose with psychedelics. Microdosing involves ingesting small amounts of a psychedelic substance, commonly psilocybin mushrooms or lysergic acid diethylamide (LSD). “Most ...

A prospective, multicenter cancer clinical trial by the ECOG-ACRIN Cancer Research Group (ECOG-ACRIN) has validated an improved method for predicting treatment benefits in patients with hormone receptor-positive (HR+) metastatic breast cancer that has spread primarily or exclusively to the bones. These patients make up a large portion of individuals who are living with advanced breast cancer—yet are routinely excluded from clinical trials that rely on standard imaging-based assessments (i.e., RECIST 1.1). The study demonstrated that metabolic change assessed by FDG-PET/CT accurately predicted progression-free ...

December 11, 2025, CLEVELAND: Cleveland Clinic researchers are presenting final Phase 1 data from their novel study of a vaccine aimed at preventing triple-negative breast cancer, the most aggressive and lethal form of the disease.   The study team found that the investigational vaccine produced an immune response in the majority (74%) of all participants and was safe and well tolerated.

Published in the journal Nature Communications, the breakthrough optical phase modulators could help unlock much larger quantum computers by enabling efficient control of lasers required to operate thousands or even millions of qubits—the basic units of quantum information. Critically, the team of scientists have developed these devices using scalable manufacturing, avoiding complex, custom builds in favor of those used to make the same technology behind ...

The energy that plants capture from sunlight through photosynthesis provides the source of nearly all of humanity’s food. Yet the process of photosynthesis has inefficiencies that limit crop productivity, especially in a rapidly changing world. A new review by University of Illinois scientists and collaborators reflects on how improving photosynthesis can bring us closer to food security. The review, which was published in Cell, was coauthored by plant biology professors Stephen Long, Amy Marshall-Colon, and Lisa Ainsworth. ...

SCOTTSDALE, Ariz. — Dec. 11, 2025 — A patient with synovial sarcoma, a soft-tissue cancer that usually occurs in the large joints of the arms and legs, is the first in Arizona treated with a new immune-cell-therapy known as TECELRA at the HonorHealth Research Institute. This new cell therapy targets a protein associated with the MAGEA4 gene, which is commonly expressed in synovial sarcoma and often occurs in the extremities, such as in the knees, though it can occur almost anywhere in the body. “The patient tolerated the cell infusion well, with early signs of tumor shrinkage,” said Justin Moser, M.D., an associate clinical ...

Hoboken, NJ., December 11, 2025 — In recent years AI has emerged as a powerful tool for analyzing medical images.

The study, led by University of Colorado Boulder and Mass General Brigham researchers, could inform efforts to improve the way psychological disorders are diagnosed and provide insight for developing novel treatments that address multiple disorders at once. The findings were published Dec. 10 in the journal Nature. “Right ...

URBANA, Ill. –  The U.S. is largely self-sufficient in agricultural food production, supported by a well-developed storage and interstate trade system. However, extreme weather events put increasing pressure on agriculture, potentially impacting the country’s ability to provide food for its growing population and underscoring the importance of maintaining a resilient food supply chain.  A new study from the University of Illinois Urbana-Champaign, published in the Proceedings of the National Academy of Sciences, looks at U.S. interstate trade for agricultural products, analyzing how weather ...

Industrial farming landscapes often have shortages of pollinators, which can cause production limitations for produce that needs them – and often lead to dire predictions (or at least online images of) supermarket produce sections empty of pollinator-dependent food. This is largely due to unsustainable practices such as heavy pesticide use, the dependence on a handful of pollinator species, and long distances from natural areas where pollinators can live. The story, however, on the globe’s ...

UNIVERSITY PARK, Pa. — Wood warblers, also called New World warblers, are some of the most colorful birds in North America, with more than a hundred species in the family ranging in color from yellow, orange and red to blue, green and pink. A new study led by researchers at Penn State has uncovered several instances of the birds passing color-related genes to other species of wood warblers, including those that are not closely related. This glimpse into the hidden evolutionary dynamics of these songbirds may help explain why some species display certain colors as well ...

Long before flowers dazzled pollinators with brilliant colors and sweet scents, ancient plants used another feature to signal insects: heat. The findings, based on an analysis of the biology and relationship between modern cycad plants and the rare beetle species that pollinate them, offer new insights into what shaped the earliest eras of plant-animal co-evolution. Plants have evolved a remarkable array of strategies to attract pollinators, including not only color and scent, but also the production of heat. Thermogenic plants generate heat through intense cellular respiration. It’s thought that in some cases, this heat, via infrared radiation, may serve as ...

Online today, the creation of fake accounts in various forms is supported by an underground market that sells text message-based verifications for these accounts. Now, researchers have developed a global index that tracks the price of these fake-account text verifications, revealing price spikes around elections and market trends that reflect national telecom costs. The findings offer policymakers a new window into how online manipulation operations take shape in real time. The internet is saturated with inauthentic activity, ranging from benign automation to networks of fake accounts promoting scams. Most platforms attempt to curb mass fake account creation through SMS-based identity verifications. ...

High-resolution data from the GHGSat satellite constellation reveal facility-level methane emissions at thousands of individual sites worldwide, according to a new study. The findings provide a far more detailed picture of methane emissions from the energy sector, offering new insights for global inventories and mitigation strategies. Methane is among the most powerful drivers of atmospheric warming a after carbon dioxide, and much of it comes from human activities – often from concentrated “point sources” such as individual oil, gas, and coal facilities. Methane emissions from these industries are generally estimated in two ways: bottom-up ...

(Boston)—Ebola (EBOV) and Marburg virus (MARV) are highly lethal viruses that cause severe disease in infected patients by extensively damaging the body. This includes the gastrointestinal tract. Severe diarrhea followed by dehydration is a major causes of death in EBOV and MARV disease patients, yet the role of the intestinal lining (epithelium) in these outcomes remain poorly understood.   A new study first-authored by Elizabeth Yvonne Flores, PhD, a recent graduate from Boston University Chobanian & Avedisian School of Medicine, BU’s National Emerging Infectious Diseases Laboratories (NEIDL) and the Center for ...
