2023-03-15
Embargoed: Not for release until 2 p.m. U.S. Eastern time Wednesday, March 15, 2023
Venus appears to have volcanic activity, according to a new research paper that offers strong evidence to answer the lingering question about whether Earth’s sister planet currently has eruptions and lava flows.
Venus, although similar to Earth in size and mass, differs markedly in that it does not have plate tectonics. The boundaries of Earth’s moving surface plates are the primary locations of volcanic activity.
New research by University of Alaska Fairbanks Geophysical Institute research professor Robert Herrick revealed ...
A nonnative tree species reclaims its prominence after extreme weather
2023-03-15
The long-term effects on forests of more extreme climate events, plus other drivers of forest change, are highly uncertain. A new study of the tropical forests across Puerto Rico and the U.S. Virgin Islands (USVI), spanning 19 years, found that after Hurricane Maria in 2017, the total biomass of a fast-growing nonnative species, the African tulip Tree (Spathodea campanulata), may again be overtaking that of the most common group of native tree species, even though, at least for young and small trees, nonnatives ...

For the first time, controlling the degree of twist in nanostructured particles
2023-03-15
Images
Micron-sized "bow ties," self-assembled from nanoparticles, form a variety of different curling shapes that can be precisely controlled, a research team led by the University of Michigan has shown.
The development opens the way for easily producing materials that interact with twisted light, providing new tools for machine vision and producing medicines.
While biology is full of twisted structures like DNA, known as chiral structures, the degree of twist is locked in—trying to change it breaks the structure. Now, researchers can engineer the degree of twist.
Such materials ...
Study unravels a cause of resistance to novel drug in patients with acute leukemia
2023-03-15
BOSTON – A new targeted drug has not only sparked remissions in patients with a common form of leukemia but also induced the cancer cells to reveal one of their schemes for resisting the drug, investigators at Dana-Farber Cancer Institute and other research centers report in a new pair of studies in the journal Nature.
One of the papers presents results of a clinical trial in which approximately 40% of patients with acute leukemia subtypes had a complete response – a disappearance of all signs of cancer – to treatment with the drug revumenib. The other paper uncovers a molecular countermove by which leukemia cells come to sidestep the drug and reassert their growth.
The ...
Making sense of scents: Deciphering our sense of smell
2023-03-15
Breaking a longstanding impasse in our understanding of olfaction, scientists at UC San Francisco (UCSF) have created the first molecular-level, 3D picture of how an odor molecule activates a human odorant receptor, a crucial step in deciphering the sense of smell.
The findings, appearing online March 15, 2023, in Nature, are poised to reignite interest in the science of smell with implications for fragrances, food science, and beyond. Odorant receptors - proteins that bind odor molecules on the surface of olfactory cells - make up half of the largest, most diverse family of receptors in our bodies; A deeper understanding of them paves the way for ...

The work promises to reduce the threats of viral contamination when harnessing bacteria to produce medicines such as insulin as well as other useful substances, such as biofuels. Currently, viruses that infect vats of bacteria can halt production, compromise ...
New laser technology developed by EPFL and IBM
2023-03-15
Scientists at EPFL and IBM have developed a new type of laser that could have a significant impact on optical ranging technology. The laser is based on a material called lithium niobate, often used in the field of optical modulators, which controls the frequency or intensity of light that is transmitted through a device.
Lithium niobate is particularly useful because it can handle a lot of optical power and has a high “Pockels coefficient”, which means that it can change its optical properties when an electric field is applied to it.
The researchers achieved their breakthrough by combining ...
How genome doubling helps cancer develop
2023-03-15
A single cell contains 2-3 meters of DNA, meaning that the only way to store it is to package it into tight coils. The solution is chromatin: a complex of DNA wrapped around proteins called histones. In the 3D space, this complex is progressively folded into a multi-layered organization composed of loops, domains, and compartments, which makes up what we know as chromosomes. The organization of chromatin is closely linked to gene expression and the cell’s proper function, so any problems in chromatin structure can have detrimental effects, including the development of cancer.
A common event in around 30% of all human cancers is “whole genome doubling” ...
Magnificent wiring
2023-03-15
NEW YORK – For a functioning brain to develop from its embryonic beginnings, so much has to happen and go exactly right with exquisite precision, according to a just-so sequence in space and time. It’s like starting with a brick that somehow replicates and differentiates into a hundred types of building materials that also replicate, while simultaneously self-assembling into a handsome skyscraper replete with functioning thermal, plumbing, security and electrical systems.

Minimizing electric vehicles’ impact on the grid
2023-03-15
National and global plans to combat climate change include increasing the electrification of vehicles and the percentage of electricity generated from renewable sources. But some projections show that these trends might require costly new power plants to meet peak loads in the evening when cars are plugged in after the workday. What’s more, overproduction of power from solar farms during the daytime can waste valuable electricity-generation capacity.
In a new study, MIT researchers have found that it’s possible to mitigate or eliminate both these problems without the need for ...
