Exposure to tobacco before birth significantly increased risk of Type 2 diabetes in adults
2024-03-20
Research Highlights:
Exposure to tobacco before birth and beginning smoking during childhood or adolescence were significantly associated with the development of Type 2 diabetes in adulthood, according to a study of nearly half a million adults in the UK Biobank.
Among those exposed to tobacco before birth or who began smoking during childhood or adolescence, participants who had a genetic predisposition to develop Type 2 diabetes and started smoking in childhood or adolescence had the highest risk of developing Type 2 diabetes.

In flies, a single brain cell can drive multiple movements of the body
2024-03-20
NEW YORK, NY — Motor neurons are the cells the brain uses to command muscles to act. Scientists typically thought of them as simple connections, much like the cables that link computers with their accessories. Now, in fly studies, researchers at Columbia's Zuckerman Institute have discovered that single motor neurons can each direct an insect’s body to move in far more complex ways than previously thought.
The findings were published in Nature on March 20.
"This is one of the first times scientists have analyzed in 3D what single motor neurons do ...
Toba supereruption unveils new insights into early human migration
2024-03-20
Modern humans dispersed from Africa multiple times, but the event that led to global expansion occurred less than 100,000 years ago. Some researchers hypothesize that dispersals were restricted to “green corridors” formed during humid intervals when food was abundant and human populations expanded in lockstep with their environments. But a new study in Nature, including ASU researchers Curtis Marean, Christopher Campisano, and Jayde Hirniak, suggests that humans also may have dispersed during arid intervals along “blue highways” created by seasonal rivers. Researchers also found evidence of cooking and stone tools that represent the oldest evidence of archery.

Bacteria subtype linked to growth in up to 50% of human colorectal cancers, Fred Hutch researchers report
2024-03-20
Researchers at Fred Hutchinson Cancer Center have found that a specific subtype of a microbe commonly found in the mouth is able to travel to the gut and grow within colorectal cancer tumors. This microbe is also a culprit for driving cancer progression and leads to poorer patient outcomes after cancer treatment.
The findings, published March 20 in the journal Nature, could help improve therapeutic approaches and early screening methods for colorectal cancer, which is the second most common cause of cancer deaths in adults in the U.S. according to the American Cancer Society.
Examining colorectal cancer tumors removed from ...
Reducing the side effects of breast and ovarian cancer treatment
2024-03-20
Some anti-cancer treatments not only target tumour cells but also healthy cells. If their effects on the latter are too strong, their use can become limiting. A team from the University of Geneva (UNIGE), in collaboration with Basel-based FoRx Therapeutics, has identified the mechanism of action of PARP inhibitors, used in particular for breast and ovarian cancer in patients carrying the BRCA gene mutation. These inhibitors block two specific activities of the PARP proteins. By blocking one of them, the toxic effect on cancer cells is maintained, while healthy cells are preserved. This work, published in the journal Nature, will help improve the efficacy of these treatments.

Skeleton-wide study of blood cell formation yields surprising findings
2024-03-20
Imagine being able to count the different types of blood cells being formed inside the tiny bones of a mouse and pinpointing the strings and clusters of cells within the bone marrow that are responsible for producing specific types of blood cells.
That’s exactly what a team of scientists led by experts at Cincinnati Children’s achieved in a far-reaching study published March 20, 2024, in the prestigious journal Nature. Their work adds unprecedented new understanding of the “elegant” and “resilient” anatomy of bone marrow while also generating evidence of unexpected variations in how the skeleton ...

An endless domino effect
2024-03-20
If it walks like a particle, and talks like a particle… it may still not be a particle. A topological soliton is a special type of wave or dislocation which behaves like a particle: it can move around but cannot spread out and disappear like you would expect from, say, a ripple on the surface of a pond. In a new study published in Nature, researchers from the University of Amsterdam demonstrate the atypical behaviour of topological solitons in a robotic metamaterial, something which in the future may be used to control how robots move, sense their surroundings and communicate.
Topological solitons can be found in many ...

Quantum tornado provides gateway to understanding black holes
2024-03-20
Scientists have for the first time created a giant quantum vortex to mimic a black hole in superfluid helium that has allowed them to see in greater detail how analogue black holes behave and interact with their surroundings.
Research led by the University of Nottingham, in collaboration with King’s College London and Newcastle University, have created a novel experimental platform: a quantum tornado. They have created a giant swirling vortex within superfluid helium that is chilled to the lowest possible temperatures. Through the observation of minute wave dynamics on the superfluid’s surface, the research team has shown that these quantum ...

Cellular architecture of lesions in MS now mapped out
2024-03-20
Using advanced methodology, scientists in Sweden were able to reveal at the cellular level how lesions in multiple sclerosis develop. The new results are presented in the journal Cell by researchers from Karolinska Institutet and Stockholm University.
Over 1,8 million people worldwide are diagnosed with multiple sclerosis, MS. In this disease, the body's immune cells attack the cells that form myelin, the so-called oligodendrocytes, which belong to the group of glial cells. Without myelin, signals between nerve cells cannot travel as fast as ...

Electronic waste rising five times faster than documented e-waste recycling: UN
2024-03-20
Geneva / Bonn - The world's generation of electronic waste is rising five times faster than documented e-waste recycling, the UN's fourth Global E-waste Monitor (GEM) reveals today.
The 62 million tonnes of e-waste generated in 2022 would fill 1.55 million 40-tonne trucks, roughly enough trucks to form a bumper-to-bumper line encircling the equator, according to the report from ITU and UNITAR.
Meanwhile, less than one quarter (22.3%) of the year's e-waste mass was documented as having been ...

Scientists uncover a causal relationship between remote extreme heat and the Canadian wildfires in 2023
2024-03-20
Wildfires are events that can have significant impacts on ecosystems and human society. In the context of global warming, there has been a notable surge in the frequency and ferocity of wildfires in the Northern Hemisphere over recent years. In 2023, Canada experienced an unprecedented wildfire event, with CO2 emissions increasing by 527.1% over the average of 2001–2022 during the months of May–August. The burned area was more than 6–7 times larger than in a normal year. Notably, both Canada and more than 15 states in the northeastern ...
Crawfish could transfer ionic lithium from their environment into food chain
2024-03-20
NEW ORLEANS, March 20, 2024 — From cell phones to watches to electric cars, lithium-ion rechargeable batteries power a plethora of devices. The increased use of this technology means more lithium could find its way into the environment as consumers discard electronic products. Now, researchers describe how lithium can accumulate in a common Southern crustacean: the crawfish. As the season for catching and eating mudbugs comes into full swing, the researchers’ findings highlight the potential implications for public health and the environment.
The researchers will present ...
Teaching teenagers to understand their feelings is key to life-long resilience, psychologist says
2024-03-20
Helping teenagers to understand what is going on inside their own brains is the key to helping them mature into resilient and independent adults, research suggests.
Sheila Redfern, a consultant clinical child and adolescent psychologist, proposes that rather than focusing on stamping out difficult behaviours, parents should teach teenagers to manage their feelings and relationships in safe ways.
Dr. Redfern says that although parenting teenagers is uniquely challenging, with concerns about social media use, self-harm, ...
