New molecule reverses Alzheimer's-like memory decline
- ScienceDaily
- 20/8/4 22:51
A drug candidate previously shown to slow aging in brain cells, successfully reversed memory loss in a mouse model of inherited Alzheimer's disease. The new research also revealed that the drug, CMS121, works by changing how brain cells metabolize fatty molecules known as lipids.

Increased global mortality linked to arsenic exposure in rice-based diets
- ScienceDaily
- 20/8/4 19:47
Rice is the most widely consumed staple food source for a large part of the world's population. It has now been confirmed that rice can contribute to prolonged low-level arsenic exposure leading to thousands of avoidable premature deaths per year.
Key brain region was 'recycled' as humans developed the ability to read
- ScienceDaily
- 20/8/4 19:47
A new study offers evidence that the brain's inferotemporal cortex, which is specialized to perform object recognition, has been repurposed for a key component of reading called orthographic processing -- the ability to recognize written letters and words.
Can sleep protect us from forgetting old memories?
- ScienceDaily
- 20/8/4 18:22
Researchers report that sleep may help people to learn continuously through their lifetime by encoding new memories and protecting old ones.
Surprisingly dense exoplanet challenges planet formation theories
- ScienceDaily
- 20/8/4 18:22
New detailed observations reveal a young exoplanet, orbiting a young star in the Hyades cluster, that is unusually dense for its size and age. Weighing in at 25 Earth-masses, and slightly smaller than Neptune, this exoplanet's existence is at odds with the predictions of leading planet formation theories.
Studies shed new light on how biodiversity influences plant decay
- ScienceDaily
- 20/8/4 18:22
Scientists have provided new insights on the relationship between plant diversity in forests and the diversity of organisms involved in their decay, such as bacteria and fungi.
Recovering data: Neural network model finds small objects in dense images
- ScienceDaily
- 20/8/4 18:22
In efforts to automatically capture important data from scientific papers, computer scientists have developed a method that can accurately detect small, geometric objects such as triangles within dense, low-quality plots contained in image data. Employing a neural network approach designed to detect patterns, the model has many possible applications in modern life.
Planet found orbiting small, cool star
- ScienceDaily
- 20/8/4 18:22
Precision measurements made with the VLBA have revealed that a small, cool star 35 light-years from Earth is orbited by a Saturn-sized planet once every 221 days.
Artificial organelles created to control cellular behavior
- ScienceDaily
- 20/8/4 18:22
Biomedical engineers have demonstrated a method for controlling the phase separation of an emerging class of proteins to create artificial membrane-less organelles within human cells. The advance, similar to controlling how vinegar forms droplets within oil, creates opportunities for engineering synthetic structures to modulate existing cell functions or create entirely new behaviors within cells....
AI may offer a better way to ID drug-resistant superbugs
- ScienceDaily
- 20/8/4 18:22
Biomedical engineers have shown that different strains of the same bacterial pathogen can be distinguished by a machine learning analysis of their growth dynamics alone, which can then also accurately predict other traits such as resistance to antibiotics. The demonstration could point to methods for identifying diseases and predicting their behaviors that are faster, simpler, less expensive and...

Epigenetic factors control the development of an organism.
Between shark and ray: The evolutionary advantage of the sea angels
- ScienceDaily
- 20/8/4 17:15
Angel sharks are sharks, but with their peculiarly flat body they rather resemble rays. An international research team has now investigated the origin of this body shape. The results illustrate how these sharks evolved into highly specialized, exclusively bottom-dwelling ambush predators and thus also contribute to a better understanding of their threat from environmental changes.
The wrong track: How papillomaviruses trick the immune system
- ScienceDaily
- 20/8/4 17:15
Specific antibodies protect us against viral infections - or do they not? Researchers studied the immune response to papillomaviruses in mice and discovered a hitherto unknown mechanism by which the pathogens outwit the immune system: At the beginning of the infection cycle, they produce a longer version of a protein that surrounds the viral genome. The body produces antibodies against this...
Nanostructures modeled on moth eyes effective for anti-icing
- ScienceDaily
- 20/8/4 17:15
Researchers have been working for decades on improving the anti-icing performance of functional surfaces and new work investigates a unique nanostructure, modeled on moth eyes, that has anti-icing properties. Moth eyes are of interest because they have a distinct ice-phobic and transparent surface. The researchers fabricated the moth eye nanostructure on a quartz substrate that was covered with a...
The problem with microwaving tea
- ScienceDaily
- 20/8/4 17:15
Through convection, as the liquid toward the bottom of a container warms up, it becomes less dense and moves to the top, allowing a cooler section of the liquid to contact the heating source. This ultimately results in a uniform temperature. Inside a microwave, however, the electric field acting as the heating source exists everywhere and the convection process does not occur.
An easier way to go veggie: Vitamin B12 can be produced during dough fermentation
- ScienceDaily
- 20/8/4 17:15
Grain-based materials fermented with Propionibacterium freudenreichii have enough vitamin B12 to be nutritionally significant. With the help of Lactobacillus brevis in the fermentation process, vegans can also be guaranteed a sufficient and safe B12 intake directly from grain-based food, without pills.
A normal DNA repair process can become a major source of mutations in cancer
- ScienceDaily
- 20/8/4 17:15
The mechanism unveiled triggers a mutation fog, causing hundreds of mutations in each tumor, which spread through the genome of lung, head-and-neck and breast cancers. Researchers have identified the antiviral APOBEC3A enzyme as the major cause of this new type of hypermutation. Published in Nature Genetics, the study shows how the mutation fog process generates many oncogenic ''cancer driver''...

New study shows how infrared lasers destroy harmful protein aggregates in Alzheimer's
- ScienceDaily
- 20/8/4 17:15
The agglomeration of proteins into structures called amyloid plaques is a common feature of many neurodegenerative diseases, including Alzheimer's. Now, scientists reveal, through experiments and simulations, how resonance with an infrared laser, when it is tuned to a specific frequency, causes amyloid fibrils to disintegrate from the inside out. Their findings open doors to novel therapeutic...
The quiet Sun is much more active than we thought
- ScienceDaily
- 20/8/4 17:14
For a long time, researchers have believed that there is not much of interest going on in the Sun during the passive period, therefore not worth studying. Now this assumption is showed to be false. This is the first time that astronomers are systematically studying the phenomena of the solar minimum.
