An averted glance gives a glimpse of the mind behind the eyes

Shakespeare once wrote that the 'eyes are the window to your soul.' But scientists have found it challenging to peer into the brain to see how it derives meaning from a look into another's eyes. Psychologists have now found a new way to study this mystery by examining the universal and embarrassing tendency to avert one's gaze when caught looking at someone else.

Monkeying around: Study finds older primates father far fewer babies

Older male rhesus monkeys sire fewer offspring, even though they appear to be mating as much as younger monkeys with similarly high social status. Sperm quality or quantity, or the survival of infants, may decline with the age of the would-be father, the new study suggests. A new study has implications for understanding some age-related aspects of male reproductive health in primates, including...

Analyzing pros and cons of two composite manufacturing methods

Airplane wings and wind turbine blades are typically created using bulk polymerization in composite manufacturing facilities. They are heated and cured in enormous autoclaves and heated molds as big as the finished part. Frontal polymerization is a new out-of-autoclave method that doesn't require a large facility investment. Researchers have conducted a study pitting one process against the other...

ALMA captures stirred-up planet factory

Planet-forming environments can be much more complex and chaotic than previously expected. This is evidenced by a new image of the star RU Lup, made with the Atacama Large Millimeter/submillimeter Array (ALMA).

AI and single-cell genomics

The study of cellular dynamics is crucial to understand how cells develop and how diseases progress. Scientist have now created 'scVelo' - a machine learning method and open source software to estimate the dynamics of gene activity in single cells. This allows biologists to robustly predict the future state of individual cells.

Chlamydia: Greedy for glutamine

If chlamydiae want to multiply in a human cell, the first thing they need is a lot of glutamine. Researchers have clarified how the pathogenic bacteria obtain this substance.

For solar boom, scrap silicon for this promising mineral

Engineers have found that photovoltaic wafers in solar panels with all-perovskite structures outperform photovoltaic cells made from state-of-the-art crystalline silicon, as well as perovskite-silicon tandem cells, which are stacked pancake-style cells that absorb light better.

Oriole bird hybridization is a dead end

A half-century of controversy over two popular bird species may have finally come to an end. In one corner: the Bullock's Oriole, found in the western half of North America. In the other corner: the Baltimore Oriole, breeding in the eastern half. Where their ranges meet in the Great Plains, the two mix freely and produce apparently healthy hybrid offspring. But according to scientists,...

New genetic cause of a form of inherited neuropathy

Inherited mutations in a gene that keeps nerve cells intact was shown, for the first time, to be a driver of a neuropathy known as Charcot-Marie-Tooth disease. This finding presents a clearer picture of the disease's genetic underpinnings that could inform the development of gene therapies to correct it.

Early Mars was covered in ice sheets, not flowing rivers, researchers say

A large number of the valley networks scarring Mars's surface were carved by water melting beneath glacial ice, not by free-flowing rivers as previously thought, according to new research. The findings effectively throw cold water on the dominant 'warm and wet ancient Mars' hypothesis, which postulates that rivers, rainfall and oceans once existed on the red planet.

Iron-rich meteorites show record of core crystallization in system's oldest planetesimals

New work uncovers new details about our Solar System's oldest planetary objects, which broke apart in long-ago collisions to form iron-rich meteorites. Their findings reveal that the distinct chemical signatures of these meteorites can be explained by the process of core crystallization in their parent bodies, deepening our understanding of the geochemistry occurring in the Solar System's youth.

Germany-wide rainfall measurements by utilizing the mobile network

Whether in flood early-warning systems or in agriculture - rainfall measurements are of great importance. However, there is a lack of accurate data for many regions in the world due to the fact that comprehensive measurements have so far been too expensive. Researchers have now succeeded in utilizing the commercial microwave link network operated by mobile network providers for Germany-wide...

Drug discovery: First rational strategy to find molecular glue degraders

Targeted protein degradation (TPD) represents a novel paradigm in drug discovery that could lead to more efficient medicines to treat diseases such as cancer. 'Molecular glue degrader'are an emerging but understudied class of small molecules that have been shown to induce degradation of proteins commonly considered 'undruggable'. Researchers have described a strategy that, for the first time,...

Novel magnetic stirrer speaks to lab equipment

A small device, called 'Smart Stirrer', performed a function of a conventional laboratory stir bar, has an integrated microprocessor and various sensors capable of wireless and autonomous report the conversion of properties of a solution. Results are sent to a computer over Bluetooth, and any changes notify the user wirelessly.
