New Haven, Conn. - Assistant Professor Mark Pagani in the Department of Geology and Geophysics at Yale and his colleagues mapped the first detailed history of atmospheric carbon dioxide between 45 - 25 million years ago based on stable isotopes of carbon in a National Science Foundation study reported in Science Express. "Through the energy we consume, each of us makes a contribution to increasing greenhouse gasses, such as carbon dioxide and methane, in the Earth's atmosphere," said Pagani....

New Haven, Conn.--Confirming findings in a previous study, Yale researchers observed an altered availability of the dopamine transporter in healthy persons with a genetic variation linked to substance abuse and attention deficit hyperactivity disorder (ADHD). "Healthy people who carry a particular variant of the dopamine transporter gene, the nine repeat allele, have significantly higher levels of dopamine transporter in the brain," said the lead author, Christopher van Dyck, M.D., associate...

New Haven, Conn. - A report by Yale scientists in the journal Cell sheds new light on how the protein Ro, a major autoantigen in patients with autoimmune disease, recognizes misfolded RNAs, creating a RNA quality control system for cells. The quality control process in the cell has been well-studied for the DNA and messenger RNA (mRNA) components for making proteins. However, little was known about what cells do with abnormal or misfolded RNAs that are not translated into protein -- such as...

One of the key motivations for revisiting the probability of life elsewhere in the universe is the surprising proclivity of life in hostile places on Earth. New findings suggest that modern organisms may have useless DNA fragments today that once saved their ancestors lives in extreme environments. Astrobiology Magazine -- Yale scientists report in the journal Nature that the "missing" genes for tRNA in an ancient parasite are made up by splicing together sequences in distant parts of the DNA...

NEW HAVEN, Conn. (AP) -- A toxic chemical used to prevent barnacles from clinging to ship hulls may cause deafness in marine mammals and could lead whales to beach themselves, Yale researchers say. The hearing loss would be the latest environmental hazard linked to TBT, a chemical already known to be harmful to some aquatic life. TBT is banned in many countries but is still widely used. Yale researchers based their theory on a study of guinea pigs, because mammals have similar ear...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
