Menstrual ‘footprints’ may act as broad personal health markers

Fri, 22 May 2026 09:00:00 -0400

WAVES, an algorithm designed to extract menstrual-cycle metrics from physiological signals such as basal body temperature, which oscillates with sex hormones, shows how different parameters change with age and helps determine whether each person maintains a stable individual pattern or personal footprint. A study based on data from 5,674 cycles from 753 women demonstrates through this tool that age is associated with higher temperatures, shorter cycles, and greater irregularity. In addition, several metrics show within-person stability, suggesting they could serve as personalized health markers.

Unmasking the X: EPAC2 shifts the fragile X landscape

Thu, 21 May 2026 09:00:00 -0400

Researchers at UCLA have shown that divergent neuronal signaling in fragile X mice converges on EPAC2, a druggable target whose inhibition restores circuit activity and alleviates core behavioral impairments.

‘Detargeted’ targeted gene therapy improves activity in Pompe

Wed, 20 May 2026 09:00:00 -0400

A new strategy aims to improve gene therapy for Pompe disease by optimizing both the genetic component that restores the function of a deficient lysosomal enzyme and the vector that delivers it to the target tissue while avoiding the liver. The findings suggest that combining an optimized transgene with a targeted capsid could significantly enhance the effectiveness of gene therapy for Pompe disease.

There are real world demonstrations of how autonomous artificial intelligence agents are poised to disrupt biomedical research, according to two papers published May 19 in Nature. Each describes an AI system that assists across the piece, from generating hypotheses to designing experiments, analyzing the data and refining hypotheses in the light of new data.

Bundibugyo is harsh reminder of need for broad vaccine strategies

Mon, 18 May 2026 12:00:00 -0400

On Sunday, May 17th, 2026, the World Health Organization classified the ongoing Bundibugyo ebolavirus outbreak in the Democratic Republic of Congo (DRC) as a public health emergency of international concern (PHEIC). The rapid escalation to PHEIC is due to several factors. Given the high number of cases, the outbreak has likely been going undetected for some time, and may be a “much larger outbreak than what is currently being detected and reported, with significant local and regional risk of spread,” according to the WHO statement. The outbreak appears to already have crossed the border from the DRC into Uganda at least twice. And all this is happening with a virus for which there are no approved treatments or vaccines.

ASGCT 2026: Directed evolution in gene therapy

Fri, 15 May 2026 09:00:00 -0400

Directed evolution has become a central pillar in gene therapy. This engineering strategy enables the generation of more efficient variants of genetic editors and delivery vectors. Molecular diversification methods are increasingly sophisticated and are now accelerated by machine learning and AI tools, as showcased at the 29th Annual Meeting of the American Society of Gene and Cell Therapy (ASGCT) held in Boston this week.

ASGCT 2026: Uncovering the mechanisms of AAV toxicity

Thu, 14 May 2026 09:00:00 -0400

Gene therapies rely on vectors to reach the target tissue where they act, such as adeno-associated viruses (AAVs) or lipid nanoparticles (LNPs), among other delivery strategies. Each combination is optimized for a specific cell type and indication, aiming to overcome challenges such as efficacy, specificity and toxicity. On May 13, 2026, two sessions included in the scientific symposia of the 29th Annual Meeting of the American Society of Gene and Cell Therapy (ASGCT), being held in Boston this week, addressed AAV-related toxicities, which have led to fatal cases in clinical trials and remain an area for improvement in approved therapies.

ASGCT 2026: Circular RNA, the new beast in gene and cell therapy

Wed, 13 May 2026 09:00:00 -0400

Circular RNA (circRNA) is not a new concept, but it is a novel strategy in the field of gene and cell therapy. While mRNA vaccines have revolutionized medicine, this RNA fragment without free ends surpasses their performance in both efficacy and durability, bringing it to the attention of several pioneering companies. The latest advances in circRNA presented at the 29th Annual Meeting of the American Society of Gene and Cell Therapy (ASGCT) clearly surpass the performance achieved with linear mRNA.

Two-step HIV vaccine induces broadly neutralizing antibodies

Tue, 12 May 2026 09:00:00 -0400

A designed chimeric virus induced broadly neutralizing antibodies against the macaque equivalent of HIV. The strategy works in two steps: first it uses an envelope protein with a mutation that reduces the glycan shield that makes it invisible to the immune system, and then it exposes the part of the protein most likely to generate these antibodies capable of blocking many variants of the virus. The macaques developed potent and diverse antibodies with this approach, which pave the way for the development of an HIV-1 vaccine.

First cruise ship hantavirus genome points to zoonotic spillover

Tue, 12 May 2026 09:00:00 -0400

The initial appraisal of the first complete genome sequence of a hantavirus isolated from a patient in Switzerland who was a passenger on the cruise ship MV Hondius is consistent with a spillover from its natural reservoir, rather than the emergence of a markedly altered virus.

In vivo mRNA gene therapy platform reprograms cytotoxic T cells

Mon, 11 May 2026 09:00:00 -0400

A new mRNA and lipid nanoparticle (mRNA-LNP) platform could selectively reprogram in vivo cytotoxic effector T cells (Teff), the cells responsible for eliminating infected or tumor cells. To achieve this, scientists at the University of Pennsylvania conjugated LNPs with fractalkine, a molecule that binds to the CX3CR1 receptor, which is a marker of Teff cells. Using this strategy, the researchers delivered an mRNA encoding new proteins such as IL‑2 or human CD62 L‑selectin, opening the door to temporarily reprogramming these cells within the body, both in the blood and in lymphoid tissue, where they reside and become activated.

Alzheimer’s, beyond the brain

Mon, 11 May 2026 09:00:00 -0400

Researchers at Daping Hospital in China have reported that liver-targeted delivery of the APOE3-Christchurch (APOE3Ch) variant, a rare protective form of apolipoprotein E, can indirectly reduce brain pathology, highlighting the therapeutic potential of peripheral approaches to Alzheimer’s disease.

Hantavirus is ‘sentinel’ more than acute pandemic threat

Fri, 08 May 2026 09:00:00 -0400

News of eight infections and three deaths so far due to an emerging zoonotic virus has brought back unhappy memories of the early days of SARS-CoV-2. At a press conference on Thursday, officials from the WHO did their best to calm the public’s fears that the MV Hondius, the ship currently heading to the Canary Islands with its remaining passengers plus assorted medical, WHO and European Center for Disease Prevention and Control staff, is the 2026 version of the Diamond Princess.

First measles treatment advances as vaccination rates drop

Thu, 07 May 2026 11:00:00 -0400

Scientists at the La Jolla Institute for Immunology have identified and characterized human antibodies that neutralize the measles virus by blocking its entry into the cell. This is the first time that antibodies have been shown to bind effectively to two essential viral proteins, creating a dual blockade that prevents infection. Unlike the current vaccine, which is based on an attenuated virus and is not recommended for immunocompromised individuals, these monoclonal antibodies could be used both as a new vaccine approach and as a treatment for the entire population.

Eyes are first prize for newco Link Biologics

Wed, 06 May 2026 09:00:00 -0400

The classic origin story for a biotech startup is that of a scientist who nurtures his work out of a university and to commercial success. For Link Biologics Ltd. and its TSG6-based pipeline, the story is the other way around; it began with now-CEO Reuben Dawkins meeting University of Manchester scientists Tony Day and Caroline Milner while he was on the lookout for “great science that needs help to make it to patients.” The three are now co-founders of Link, which spun out of the University of Manchester in 2021 and has four programs in three indications, all based on TSG-6 biology.

Cytospire raises £61M series A to target EGFR in solid tumors

Tue, 05 May 2026 09:00:00 -0400

Next-generation T-cell engager (TCE) specialist Cytospire Therapeutics Ltd. has raised £61 million (US$82.7 million) in a series A round, equipping it to advance the lead program CYT-X300 to the clinic in the treatment of EGFR-positive solid tumors. The company’s pan gamma delta (γδ) TCEs are designed to overcome problems with cytokine release syndrome, on-target effects on healthy cells, and the excessive activation of CD3 that have occurred with earlier bispecific antibodies that bind to the CD3 receptor on T cells.

Liposomes displaying Env trimers drive HIV apex-focused responses

Mon, 04 May 2026 09:00:00 -0400

A new vaccination strategy designed to induce antibodies that recognize the apex of the HIV Env protein uses Env trimers displayed on liposomes to increase their density and orient them correctly. This presentation enhanced apex-focused antibody responses in macaques, and the monoclonal antibodies isolated after immunization showed binding modes and structural features resembling human broadly neutralizing antibodies (bNAbs), indicating that the vaccine can steer the antibody response toward this vulnerable site.

Quintuple GLP-1-GIP-PPAR agonist for obesity and diabetes control

Thu, 30 Apr 2026 09:00:00 -0400

A new molecule combines the action of two incretins, GLP-1 and GIP, hormones that regulate glucose and appetite, with lanifibranor, a triple agonist of peroxisome proliferator activated receptors (PPAR α/γ/δ). GLP-1-GIP-Lani enables targeted delivery of the PPAR agonist to cells that express incretin receptors, enhancing weight loss, improving glucose control and reducing inflammation in obese mice. In these models, it surpassed the effects of GLP-1 receptor agonists such as semaglutide and GLP-1-GIP co-agonists such as tirzepatide in reducing body weight, improving glycemic control and enhancing metabolic outcomes during active treatment.

Innervation can slow, as well as speed, tumor growth, study finds

Wed, 29 Apr 2026 10:00:00 -0400

Innervation by the sympathetic nervous system is typically a boon to tumors. But researchers from Weill Cornell Medicine and colleagues have shown that in some cases, the relationship between tumors and the nervous system is more complex. Depending on context, innervation can either assist or obstruct tumor growth. “The nervous system typically has been considered as a driver of cancer growth, but here we’ve found that it can be a brake on cancer growth in some contexts,” said David Simon, an assistant professor of biochemistry and biophysics at Weill Cornell Medicine.

Criminal charges filed against top Fauci aide

Tue, 28 Apr 2026 12:00:00 -0400

An alleged coverup of NIH-funded gain-of-function research at China’s Wuhan Institute of Virology has led to criminal charges against a former career scientist and top aide to Tony Fauci, the head of the National Institute of Allergy and Infectious Diseases in the time of the COVID-19 pandemic.

Plasticity, properly parsed, provides psychiatric platform

Mon, 27 Apr 2026 09:00:00 -0400

If Benjamin Braddock, of The Graduate fame, were a young neuroscientist in the 21st century instead of a liberal arts graduate in 1967, the advice he received from his parents’ neighbor might not have been “One word: plastics!” but “One word: plasticity!” Plasticity is a hot concept in neuropsychiatric disorders. New and old treatment modalities, these days, are said to work as psychoplastogens or neuroplastogens.

Pharma industry faces long haul to get return on investment from AI

Fri, 24 Apr 2026 09:00:00 -0400

Artificial intelligence tools are springing up at multiple points along drug discovery and development, but despite the hype, as yet there is minimal return on investment (ROI). “I would say a lot of companies sort of get this big excitement about AI, but then when you look at how much ROI they get, it’s actually very little. And that’s because the workflow and the process, end-to-end, isn’t mapped to really understand where AI can truly make an impact,” said Laura Matz, chief science and technology officer at Merck KGaA.

AI opens the way to systematic risk assessment of zoonotic potential of viruses

Wed, 22 Apr 2026 11:00:00 -0400

Researchers in the U.K. have developed an AI-driven method of identifying viruses in wild animals with the potential to spillover into humans. The technique makes it possible to use the genome sequences of the spike proteins by which viruses enter host cells to assess the potential to infect humans without having to isolate an individual virus and tests its infectivity in the lab.

Kaleidoscope-like ‘engineered disorder’ expands imaging potential

Tue, 21 Apr 2026 09:00:00 -0400

A new metasurface design strategy that replaces rigid order with “engineered disorder” could significantly increase how many optical functions can be integrated into a single ultra-thin device without increasing size or complexity, according to a study published in Nature Communications. The study challenges a longstanding assumption in optical engineering that highly ordered, periodic structures are required to precisely control light.

At AACR: Epigenetic fingerprints in metastases track tumor origin

Tue, 21 Apr 2026 09:00:00 -0400

When a tumor migrates and colonizes another tissue or organ, it can be identified as a metastasis, but its origin is not always clear. Now, a study based on machine learning has identified DNA-methylation patterns that reveal the type of tissue a cancer comes from when the primary tumor cannot be found. This technique could help guide more specific treatments for patients with cancers of unknown primary, who today often receive broad, nontargeted chemotherapy.

Whole genome sequencing unveils blood cancer trajectory

Mon, 20 Apr 2026 12:00:00 -0400

A new study tracking the genomic evolution of chronic myeloproliferative neoplasms has shown that progression to myelofibrosis or acute myeloid leukemia is encoded in mutations that occur years before the transformation is clinically evident.
