Rainforest's next generation of trees threatened 30 years after logging
2024-03-12
Rainforest seedlings are more likely to survive in natural forests than in places where logging has happened – even if tree restoration projects have taken place, new research shows.
Scientists monitored over 5,000 seedlings for a year and a half in North Borneo.
They studied a landscape containing both natural forest and areas logged 30 years ago – some of which were recovering naturally, while some had been restored by methods including tree planting.

Expertly engineered saccharomyces cerevisiae yeast strain in the optimized production of carotenoids
2024-03-12
More than 90% of the commercially available carotenoids are synthetically produced using chemicals. To meet the increasing demand for cost-effective natural compounds in carotenoid synthesis, researchers at Xiamen University, China, have developed an engineered S. cerevisiae yeast strain capable of selectively overproducing carotenoids. They redesigned the genomic sequence and critical pathways to optimize carotenoid production. This novel and successful research approach can be extended to other model ...
Beer byproduct behind Marmite could help us recycle metal waste
2024-03-12
When we recycle electronic devices we can no longer use, we expect to make the most out of the precious natural resources that went into building them. But electronic waste is notoriously difficult to recycle, because it’s hard to separate the different metals in the waste from each other. Scientists have now found a way of selectively capturing metals from a waste stream using spent brewer’s yeast, the same beer byproduct that goes into Marmite. Not only that: the yeast can be reused, making the process even more eco-friendly.
“Electronic waste is difficult to recycle because it is very heterogeneous,” said Dr Klemens Kremser ...
Guessing game: Response may bias understanding of future scenarios
2024-03-12
Does previous experience bias a person in future estimations? Yes, Osaka Metropolitan University researchers in Japan report, but only if the person engages higher processing powers by responding, as opposed to simply observing.
They made their findings through experiments involving participants estimating the number of dots flashed on a screen. Participants either had to input their estimate before making another estimate on a new set of dots or were not prompted to do anything but observe. The researchers found ...

New method for triggering and imaging seizures can help guide epilepsy surgery
2024-03-11
Researchers have developed a new method for triggering and imaging seizures in epilepsy patients, offering physicians the ability to collect real-time data to tailor epilepsy surgery. In contrast to previous practice, where physicians from neurology and nuclear medicine had to wait for hours to days in hopes of capturing the onset of a seizure, the new method is convenient, spares resources, and is clinically feasible. This research was published in the March issue of The Journal of Nuclear Medicine.
People with epilepsy and seizures who do not respond to medication are often helped by brain surgery. The goal ...
Giving particle detectors a boost
2024-03-11
Device could help facilitate the operation of new particle colliders, such as the Electron-Ion Collider.
In particle colliders that reveal the hidden secrets of the tiniest constituents of our universe, minute particles leave behind extremely faint electrical traces when they are generated in enormous collisions. Some detectors in these facilities use superconductivity — a phenomenon in which electricity is carried with zero resistance at low temperatures — to function.
For scientists to more accurately observe the behavior of these particles, these weak electrical signals, or currents, need ...

This protein pic could help develop new cancer treatments
2024-03-11
Some cancerous tumors hijack proteins that act as “brakes” on our immune system and use them to form a sort of shield against immune recognition. Immunotherapy treatments have been created that turn off these “brakes” and allow our body to attack foreign-looking cancer cells. To further advance such treatments, researchers at Stanford University and New York University have published a new structure of one of these brake proteins, LAG-3. Their work contains key details of the molecule’s structure, as well as information about how the LAG-3 protein functions.
Although over a dozen immunotherapies targeting LAG-3 are in development, and one is already FDA approved, ...
