Mosquitoes’ feeding tubes make ultrafine 3D-printing nozzles

admin — Mon, 22 Dec 2025 17:39:14 +0000

Researchers in ɬ�﷬’s Department of Mechanical Engineering and at Drexel University have developed an innovative manufacturing technique that makes female mosquito proboscides, or feeding tubes, into high-resolution 3D-printing nozzles. With its unique geometry, structure and mechanics, the proboscis enables printed line widths as fine as 20 microns, or a little smaller than a white blood cell. This is roughly twice as fine as what commercially available print

New therapeutic strategies show promise against a hard-to-treat prostate cancer

admin — Thu, 20 Nov 2025 14:05:40 +0000

A new study has uncovered promising therapeutic strategies against one of the deadliest forms of prostate cancer.

ɬ�﷬ researchers at the Rosalind and Morris Goodman Cancer Institute (GCI) identified a mechanism driving neuroendocrine prostate cancer, a rare and highly aggressive subtype for which there currently are no effective treatment options.

Microencapsulated B-vitamins help dairy cows produce more milk with fewer emissions

admin — Thu, 11 Dec 2025 16:38:40 +0000

A new international study led by ɬ�﷬ in collaboration with Jefo Nutrition shows that supplementing dairy cow diets with microencapsulated B-vitamins can significantly reduce greenhouse gas emissions while increasing milk yield and quality. The use of the feed additive cut global warming potential, an internationally standardized measure of climate impact, by up to 18 per cent across seven countries.

Exoplanet is observed shedding its atmosphere in real time

Using the James Webb Space Telescope (JWST), a team led by ɬ�﷬ researcher Vigneshwaran Krishnamurthy has observed a giant cloud of helium gas evaporating from a distant giant exoplanet called WASP-107b.

Do supervised consumption sites bring increased crime? Study suggests that’s a myth

admin — Tue, 06 Jan 2026 16:59:41 +0000

Overdose prevention sites and supervised consumption sites in Toronto are not associated with long-term increases in local crime, ɬ�﷬ researchers have found.

Over 10 years, crime reports remained stable or declined in neighbourhoods where sites opened, the researchers said. Their findings land amid debates across Canada about how harm reduction services intersect with public health and safety.

Fine particles in pollution are associated with early signs of autoimmune disease

admin — Mon, 15 Dec 2025 14:58:39 +0000

A new study has linked air pollution exposure and immune-system changes that often precede the onset of autoimmune diseases.

ɬ�﷬ researchers analyzing Ontario data found that fine particles in air pollution are associated with higher levels of a biomarker linked with autoimmune diseases, such as systemic lupus.

Kering Foundation, SVRI and ɬ�﷬ launch research program on the intersection of violence against women and children

admin — Mon, 08 Dec 2025 16:17:30 +0000

The Kering Foundation, in partnership with ɬ�﷬ and the Sexual Violence Research Initiative (SVRI), is launching an innovative research program to tackle the often-overlooked links between violence against women and violence against children – a critical global issue with deep social impact.

This multi-year initiative will strengthen evidence-based, locally led research to understand how violence against women and children intersects and to identify effective solutions through programs, services, and interventions.

Navigating the dating world? It’s important to know what you want, researchers say

admin — Tue, 02 Dec 2025 14:38:47 +0000

Single people who date without a clear understanding of what they are looking for in a relationship experience more loneliness and decreased life satisfaction, ɬ�﷬ researchers have found.

New light-triggered microneedle patch could make IVF hormone delivery painless and automated

admin — Wed, 07 Jan 2026 14:54:08 +0000

A ɬ�﷬ research team has developed a painless, automated way to deliver in vitro fertilization (IVF) hormones using a light-activated microneedle patch, an innovation that could ease one of the most stressful parts of fertility treatment and open new possibilities for other diseases that require frequent, time-sensitive injections.

IVF patients must inject themselves with hormones daily at specific times in the weeks leading up to egg retrieval, a process that can be physically and emotionally taxing.

Bringing environmental policymakers together to focus on the future sparks empathy for nature and later generations, ɬ�﷬ study finds

admin — Fri, 21 Nov 2025 15:19:04 +0000

When environmental policymakers are invited to imagine the future together, they don’t just think differently, they feel differently, too.

ɬ�﷬ researchers develop a cheaper, safer material for use in solar panels, sensors and optical devices

admin — Mon, 08 Dec 2025 16:38:33 +0000

Using proteins from a common tobacco plant virus, ɬ�﷬ chemistry researchers have developed a simple, eco-friendly way to arrange gold nanoparticles into ultrathin sheets, strengthening the particles’ optical properties. The result: cheaper, safer materials for solar panels, sensors and advanced optical devices.

ɬ�﷬ researcher unveils new model that more accurately measures greenhouse gas emissions from natural gas

admin — Fri, 09 Jan 2026 14:07:07 +0000

ɬ�﷬ engineering researchers have introduced an open-source model that makes it easier for experts and non-experts alike to evaluate greenhouse gas emissions from U.S. natural gas supply chains and yields more accurate results.

ɬ�﷬ researchers develop stretchable, biodegradable battery using eco-friendly acids

admin — Tue, 25 Nov 2025 15:55:08 +0000

Researchers with ɬ�﷬’s Trottier Institute for Sustainability in Engineering and Design have developed a stretchable, eco-friendly battery suitable for use in wearable and implantable devices. The battery, which uses citric or lactic acid and gelatin to achieve flexibility and performance without relying on toxic materials, stands to reduce electronic waste.

New evidence challenges understanding of Parkinson’s disease

admin — Wed, 17 Dec 2025 14:17:23 +0000

A ɬ�﷬-led study is challenging a popular theory about how dopamine drives movement, a discovery that could shift how scientists think about Parkinson’s disease treatments.

Published in Nature Neuroscience, the research found dopamine does not set the speed or force of each movement, as had been thought. Instead, it appears to act as the underlying support system that makes movement possible.

Brain discovery opens door to earlier detection of metabolic syndrome in women

admin — Tue, 09 Dec 2025 14:07:07 +0000

ɬ�﷬ researchers have identified a brain function that helps explain why childhood stress raises metabolic health risks for some women later in life.

A new study found that variations in the brain’s insulin receptor network affect how women respond to early-life adversity. This effect has a lesser impact in men, suggesting there is a sex-specific process at play.
