As of October 2024, 3,000 patients had used Piction’s clinic. So far, it is available in Connecticut, Florida, Massachusetts, New Hampshire and Washington. The service is covered by several major insurance companies, or patients can pay $119 out-of-pocket for each consultation.

Eleni Linos, a professor of dermatology and epidemiology who directs the Stanford Center for Digital Health, and who has no connection with Piction, says: “I’m really optimistic about how this technology can help patients get the best care they can get, while at the same time helping doctors.” — Esther Landhuis.

A groundbreaking discovery has rocked the field of neutrino astronomy—scientists have detected an ultra-high-energy neutrino using the KM3NeT telescope, with an energy level 16,000 times greater than the most powerful collisions at the Large Hadron Collider. These elusive “ghost particles” provid

NASA’s Lucy mission is about to fly past asteroid Donaldjohanson, a strange, elongated rock in the main belt. While this three-mile-wide object isn’t one of Lucy’s primary targets, the April 20 flyby serves as a full dress rehearsal before the spacecraft heads toward the Trojan asteroids near Jup

The human brain can learn to filter out distracting or disruptive stimuli, such as a bright roadside billboard or a flashing online banner, through repeated exposure. Researchers from Leipzig University and Vrije Universiteit Amsterdam have demonstrated this effect using electroencephalography (EEG), showing that early visual processing in the brain changes with experience. Their findings were recently published in The Journal of Neuroscience.

Distractions tend to become easier to ignore after repeated encounters. This process, known as learned suppression, plays a key role in the visual system and complements our ability to consciously direct attention. In a series of EEG experiments with 24 participants of all genders, the researchers examined how learning affects attention to highly noticeable distractions, particularly when such distractions consistently appear in the same location.

A new study from Weill Cornell Medicine provides insights into how cells maintain the tiny end caps of chromosomes as they divide, a key process in keeping cells healthy. Using yeast, the researchers reveal protein interactions that could explain how the enzyme telomerase is tightly regulated to prevent cells from dividing uncontrollably or aging prematurely.

The preclinical study, published April 17 in Nucleic Acids Research, brings us closer to understanding the mechanisms behind aging and cancer.

Before cells divide, they replicate the double-stranded DNA of each chromosome. The does a good job of copying the nucleotide sequences until it gets to the telomeres, the end caps of chromosomes that safeguard the genetic material from damage and normally shorten with aging. That’s when telomerase steps in and produces an overhang in which one DNA strand is a little longer than the other.
