Plants are extremely sensitive to lengths of nights and days and use the information to keep track of seasons, information crucial to their life cycles. Yale researchers shed new light on how plants use their photoreceptors as biochemical light switches...
As cells age, they accumulate signs of DNA damage. Breaks in both strands of the DNA molecule are especially toxic and have been linked to increased genomic instability and cancer risk with age. A new Yale study of yeast quantifies how the age of a cell...
Even in patients who receive long-term anti-retroviral treatment, cells containing HIV remain in the cerebrospinal fluid of half of those treated for the disease, and those individuals are more likely to experience cognitive deficits than those without...
Why does coffee smell like coffee, whether on a San Diego beach or in the middle of Manhattan? Olfactory systems can distinguish incoming odors from backgrounds, even though different odors activate many of the same olfactory receptors.
A new theoretical...
A prevailing theory in neuroscience holds that people make decisions based on integrated global calculations that occur within the frontal cortex of the brain.
However, Yale researchers have found that three distinct circuits connecting to different...
Of all forms of memory, episodic memory is the most intimate. We recall the sequences of events that happen to us — a marriage, a visit to a foreign country, a personal achievement — in great autobiographical detail. But scientists have disagreed about...
Even after antibiotic treatment, some Lyme disease patients continue to suffer from debilitating arthritis. A new Yale study may explain why.
The tick-borne bacterium Borrelia burgdorferi leaves behind parts of its cell wall in patients’ joints, which...
Within hours after fertilization, a unique genome forms from chromosomes contributed by the egg and sperm. However, this new genome is initially inactive and must be “awakened” to begin the transcription of its DNA and start embryonic development. How...
