WhatsApp announced that it is introducing new filters and backgrounds to improve user experience during video calls. With this update, WhatsApp aims to make conversations more interesting and fun by allowing users to personalize their video call settings.

With filters aimed at adding a personal touch to virtual interactions, users can choose from a variety of options such as adding color, increasing brightness or applying creative effects to their videos. Backgrounds provide a simple and stylish virtual environment image, such as a friendly coffee shop or a cozy living room, while preserving privacy.

WhatsAppoffers 10 filters and 10 backgrounds for users to choose from. These filters include options such as Warm, Cold, Black & White, Light leak, Dreamer, Refracted Light, Fisheye, Vintage TV, Frosted glass and Dual tone. Background options include Blur, Living room, Office, Cafe, Pebbles, Gourmet, Brush Strokes, Beach, Sunset, Celebration, and Forest.

Additionally, WhatsApp offers Retouch and Low Light options that enhance the user’s appearance and environment during calls by naturally improving brightness and clarity.

These features, which will be available worldwide in the coming weeks, can be accessed by selecting the effect icons in the upper right corner of the screen during both one-on-one and group video calls.

According to the research, it turns out that men may actually not like the smell of fertile women. Here are all the details.

Scientists have debunked the popular myth that men are more attracted to the scent of women at their fertile peak, according to a new study. Previous research, including one published as recently as 2018, has suggested that heterosexual men’s interest in women’s body odor may likely vary with the ovulatory cycle, peaking around the fertile window. Unlike other female primates, women do not physically announce their fertile periods, but it remains unclear whether and how chemical information about female fertility might be revealed in body odor.

Contrary to popular myth, the new study, published in the journal Proceedings of the Royal Society B, showed that the menstrual cycle does not have a significant impact on men’s scent-based attraction to women. Findings reveal men’s ability to detect menstrual cycle-related changes in women’s body odor questioning. In the study, 91 heterosexual men aged 19 to 40 rated the scents of 29 stranger women at different stages of their menstrual cycle in terms of attractiveness, pleasantness and intensity, simulating a first encounter. The researchers made sure that no man in the study smelled the same woman’s scent twice. Each woman’s fertility status was confirmed by urine tests as well as saliva levels of the hormones estradiol and progesterone. However, there was no improvement in attractiveness for men. This brought into question what was known so far.

Scientists have identified a unique brain signal that plays a key role in shaping the impact of rewards on human behavior; This is an advance that could lead to new treatments for depression. Here are all the details.

Researchers from Texas Children’s Hospital say the findings could help develop therapies specifically to treat anhedonia, or the attention-seeking symptom associated with depression. People enjoy a variety of mental and physical activities, sensory experiences, and social interactions that affect the way the brain is wired. Rewards in the form of food treats, gifts, or words of appreciation play an important role in shaping the brain and behavior in both humans and animals by serving as positive reinforcement. But scientists say the exact brain processes behind this phenomenon and how it affects future behavior are largely unknown.

In the new study, published in the journal Nature Communications, researchers identified unique patterns of activity in the frontal lobe of the brain that may be a signature in the underlying processes associated with reward recognition. This suggests that brain activity may play a role in how people determine subsequent choices after a reward and shape future behavior. Specific brain activity is also altered in patients with depression found.

“Our study addressed a long-standing fundamental question in neuroscience – what specific brain region and signal regulates the classical reward bias response?” Thanks to this study, there may be hope for depression patients.
