A genetic circuit guides microorganisms to stop fighting and work together in a cell factory

Bacteria, fungi, and microalgae—living things too small to be seen with the naked eye—are microorganisms that are commonly used for chemical production via their fermentation. The development of Mycoplasma mycoides in 2010, an artificial microorganism, has highlighted the technology that is utilized to develop industrial microorganisms such as Escherichia coli and yeast as "cell factories" for...

Two new young open clusters discovered

By analyzing the data from ESA's Gaia satellite, astronomers have detected two new young open clusters. The newfound clusters, designated Casado 82 and Casado-Hendy 1, are located in a nearby primordial group of open clusters. The finding is reported in a paper published November 23 on arXiv.org.

Gorgeous rainbow-colored, stretchy film for distinguishing sugars

Rainbows and sugar may conjure up images of a certain leprechaun-branded breakfast cereal. But now, researchers in ACS Nano report a kaleidoscope-like film for telling different sweeteners apart that displayed multiple colors when stretched by hand. When evenly stretched with a simple apparatus, the material enhanced the unique shifts in fluorescence intensity of 14 sugars tagged with a dye,...

Designing better water filters with AI

Even the best water filters let some things through, but designing improved materials and then testing them is time consuming and difficult. Now, researchers in ACS Central Science report that artificial intelligence (AI) could speed up the development of promising materials. In a proof-of-concept study, they simulated different patterns of water-attracting and water-repelling groups lining a...

How chemists are tackling the plastics problem

We tend to lump all plastics into one category, but water bottles, milk jugs, egg cartons, and credit cards are actually made from different materials, as you’ve probably noticed while trying to figure out what can go in your recycling bin. Once they’ve reached a recycling facility, the plastic must be separated, a process that can be slow and costly, and ultimately limits which materials,...

It’s just a first step, but this new Alzheimer’s drug could be a huge breakthrough | Jonathan Schott

Recent lecanemab trials are reason for hope. But the NHS and other health services may struggle to deliver these new treatmentsIt is 20 years since the last drug for Alzheimer’s was licensed in the UK. Since then, huge advances have been made in our understanding of the disease’s causes. Better diagnostic tests are available, and we may now be on the cusp of new treatments that could have an...

Elon Musk has created a toxic mess for the LGBTQ+ community. I would know.

A mere day after Elon Musk reactivated Rep. Marjorie Taylor Greene’s Twitter account, she tweeted that I’m a “communist groomer,” presumably because I’m a gay Jewish Democratic elected official from San Francisco.  Greene’s tweet also promoted her proposed federal law to ban gender-affirming care for transgender youth and to make it effectively impossible for adult transgender...

Panama confronts illegal trafficking of animals

In a tropical forest beside the Panama Canal, two black-handed spider monkeys swing about their wire enclosure, balanced by their long tails. They arrived at this government rehabilitation center after environmental authorities seized them from people who had been keeping them as pets.

Hawaii volcano eruption has some on alert, draws onlookers

The first eruption in 38 years of the world's largest active volcano is attracting onlookers to a national park for "spectacular" views of the event, and it's also dredging up bad memories among some Hawaii residents who have been through harrowing volcanic experiences in the past.

New study examines success of Monterey Bay Aquarium sea otter rehabilitation program

A new study, authored by experts at Monterey Bay Aquarium and their partners, examines the development of its landmark sea otter rehabilitation program and how it can support sea otter recovery and reintroduction. Published in the Journal of Zoological and Biological Gardens, the research recounts its successes and challenges, showing how the program benefits both species recovery and ecosystem...

New quantum computing feat is a modern twist on a 150-year-old thought experiment

A team of quantum engineers at UNSW Sydney has developed a method to reset a quantum computer—that is, to prepare a quantum bit in the '0' state—with very high confidence, as needed for reliable quantum computations. The method is surprisingly simple: it is related to the old concept of 'Maxwell's demon', an omniscient being that can separate a gas into hot and cold by watching the speed of...

Either in lockdown or preparing for lockdown: life amid zero-Covid in Beijing

Living under China’s policy to suppress Covid cases means days are filled with health codes, the constant threat of shutdowns and moments of hopeLife in Beijing these days is spent either in lockdown or preparing for lockdown. Stockpiling food at home, just in case, has become the new norm. Meeting friends is hard because every few weeks one of us is sealed inside their home for days. Carrying...

This glittering group of stars, shining through the darkness like sparks left behind by a firework, is NGC 2660 in the constellation Vela, best viewed in the southern sky. NGC 2660 is an open cluster, a type of star cluster that can contain anywhere from tens to a few hundreds of stars loosely bound together by gravity.

NASA scientists create black hole jets with supercomputer

Leveraging the NASA Center for Climate Simulation (NCCS), NASA Goddard Space Flight Center scientists ran 100 simulations exploring jets—narrow beams of energetic particles—that emerge at nearly light speed from supermassive black holes. These behemoths sit at the centers of active, star-forming galaxies like our own Milky Way galaxy, and can weigh millions to billions of times the mass of the...

Researchers investigate neuron differentiation in fruit fly brains

The brains of all higher-order animals are filled with a diverse array of neuron types, with specific shapes and functions. Yet, when these brains form during embryonic development, there is initially only a small pool of cell types to work with. So how do neurons diversify over the embryo's development? Researchers know that neural stem cells called neuroblasts divide multiple times to...

Developing the low-energy ion spectrometer for the Chinese BeiDou-3 satellite

In our daily lives, we rely on weather forecasts to know whether it will rain tomorrow. The monitoring and prediction of space weather such as geomagnetic storms and substorms are also vital for the operation safety of satellites outside the atmosphere and the living conditions of astronauts in space. However, space weather is far more unpredictable than the weather on Earth, which depends on...

Most Asian countries are far behind biodiversity targets for protected areas, finds study of 40 countries

Protected areas are one of the most effective tools for safeguarding biodiversity, but new research published today has found that most Asian countries failed to achieve a global minimum target of protecting at least 17% of land by 2020. Under current trends, the outlook for achieving the Global Biodiversity Framework's 2030 target to protect at least 30% of land is bleak, with Asia set to miss...

Climate change will cause Pacific's low-oxygen zone to expand even more by 2100, study finds

For thousands of kilometers along the western coasts of the Americas, low-oxygen waters known as oxygen minimum zones stretch out into the Pacific Ocean. In part due to climate change, this oxygen-starved region is likely to get wider and deeper, expanding by millions of cubic kilometers by the end of the century, models in a new study predict. Larger oxygen minimum zones threaten marine...
