Researchers identify why cancer immunotherapy can cause colitis

Researchers identify why cancer immunotherapy can cause colitis
2024-01-05
Researchers at the University of Michigan Health Rogel Cancer Center have identified a mechanism that causes severe gastrointestinal problems with immune-based cancer treatment. They also found a way to deliver immunotherapy’s cancer-killing impact without the unwelcome side effect. The findings are published in Science. “This is a good example of how understanding a mechanism helps you to develop an alternative therapy that’s more beneficial. Once we identified the mechanism causing the colitis, we could then develop ways to overcome this problem and prevent colitis while preserving the anti-tumor effect,” said senior ...

Can we fight back against Parkinson’s disease? These research volunteers hope so

2024-01-05
About three years before he retired, David Campbell noticed something weird happening as he typed. Whenever he tried to hit a letter, say “a,” he’d get “aaa,” like the keyboard was jamming or his finger was triple-tapping the key. That wasn’t the only thing that seemed off—his sense of smell was faltering. “Little things,” he says, “that I didn’t think of as being a big deal.” A couple of weeks after he retired in fall 2020, Campbell learned the little things weren’t ...

After COP28 “insider” climate activists will become increasingly important, study suggests.

2024-01-05
Climate campaigners will increasingly adopt “insider activist” roles, working to change or challenge their organisations from the inside rather than the outside, a new study says. Research led by the University of Exeter identifies different types of climate activists. As well as “insiders”, there are others who seek to undermine, or even damage, climate-recalcitrant organisations they are members of in the hope of change. The study says the growing climate backlash against traditional outside climate activism and rise of corporate “greenwashing” means collaborating or ...

Protected areas for elephants work best if they are connected

Protected areas for elephants work best if they are connected
2024-01-05
PRETORIA, SOUTH AFRICA – Conservation measures have successfully stopped declines in the African savanna elephant population across southern Africa, but the pattern varies locally, according to a new study. The evidence suggests that the long-term solution to elephant survival requires not only that areas are protected but that they are also connected to allow populations to stabilize naturally, an international research team says. Their study, published on January 5th in the peer-reviewed journal Science Advances, collected survey estimates and calculated growth rates for ...

Inhalable sensors could enable early lung cancer detection

Inhalable sensors could enable early lung cancer detection
2024-01-05
CAMBRIDGE, MA -- Using a new technology developed at MIT, diagnosing lung cancer could become as easy as inhaling nanoparticle sensors and then taking a urine test that reveals whether a tumor is present. The new diagnostic is based on nanosensors that can be delivered by an inhaler or a nebulizer. If the sensors encounter cancer-linked proteins in the lungs, they produce a signal that accumulates in the urine, where it can be detected with a simple paper test strip. This approach could potentially replace or supplement the current gold standard for diagnosing lung cancer, low-dose computed tomography (CT). It ...

New study reveals crucial 'housekeeping' genetic elements and their potent role to fight cancer

New study reveals crucial housekeeping genetic elements and their potent role to fight cancer
2024-01-05
Technological advancements have enabled scientists to comprehensively explore genetic control elements, unraveling the complexities of gene activation mechanisms in our genetic code. New evidence challenges the simplistic view that cis-regulatory elements (CREs) are mere on/off switches for genes, emphasizing their ability to exhibit complex behaviors, such as the simultaneous enhancement of gene activity and initiation of gene transcription, e.g., simultaneous enhancer and promoter activities. These switches aren't only important for the enhancement ...

Mixed forests protect coastal areas from tsunami impacts better than monoculture forests

Mixed forests protect coastal areas from tsunami impacts better than monoculture forests
2024-01-05
Coastal forests in Japan had predominantly been afforested with black pine (Pinus thunbergii), a shade-tolerant tree species that can withstand dry land ecosystems and harsh coastal environments. This afforestation initiative, dating back to the Edo period (1603~1867), aimed to mitigate the deleterious effects of robust winds and sand blowing. Subsequent to the Great East Japan Earthquake in 2011, interest shifted to the potential protective effects of coastal forests in reducing the destructive power of tsunamis. The Great East Japan Earthquake tsunami damaged a total of 2,800 hectares (ha; 10,000 square meters) of ...

UofL study shows nicotine in e-cigarettes may not be harmless, as some claim

2024-01-05
With the start of a new year, smokers and vapers may have resolved to quit or cut back on the habit to improve their health. They may want to use caution, however, if their strategy involves switching from cigarettes to e-cigarettes, considered by some to be a less harmful alternative. A new study from the University of Louisville shows the nicotine in certain types of e-cigarettes may be more harmful than others, increasing risk for irregular heartbeat, or heart arrhythmias. A popular claim is that nicotine in ...

Ancestors of primates lived in pairs

2024-01-05
A study carried out by CNRS1 scientists working with an international team has revealed that around 70 million years ago, when dinosaurs existed, the ancestors of primates most commonly lived in pairs. Only 15% of them opted for a solitary lifestyle. This discovery — that our ancestors adopted variable forms of social organization — challenges the hitherto commonly accepted hypothesis that at the time of dinosaurs, the ancestors of primates lived alone, and that pair living evolved much later. Most likely, pair living offered significant benefits, such as easier reproduction and reduced costs of thermoregulation by huddling in pairs. While several studies have already been conducted ...

Mysterious missing component in the clouds of Venus revealed

Mysterious missing component in the clouds of Venus revealed
2024-01-05
What are the clouds of Venus made of? Scientists know it’s mainly made of sulfuric acid droplets, with some water, chlorine, and iron. Their concentrations vary with height in the thick and hostile Venusian atmosphere. But until now they have been unable to identify the missing component that would explain the clouds’ patches and streaks, only visible in the UV range. In a new study published in Science Advances, researchers from the University of Cambridge synthesised iron-bearing sulfate minerals that are stable under the harsh chemical conditions in the Venusian clouds. Spectroscopic analysis revealed that a combination of two minerals, rhomboclase and acid ferric ...
