Not much time for original writing today, but here are excerpts from a few recent ScienceDaily reports I have found interesting:
How Chimps Deal With Death: Studies Offer Rare Glimpses
ScienceDaily (Apr. 27, 2010) — Two studies in the April 27th issue of Current Biology, a Cell Press publication, offer rare glimpses into the ways that chimpanzees deal with the deaths of those closest to them. In one case, researchers describe the final hours and moment of death of an older female chimp living in a small group at a UK safari park as captured on video...
In the days leading up to the chimp's death, the group was very quiet and paid close attention to her, the researchers report. Immediately before she died, she received much grooming and caressing from the others, who appeared to test her for signs of life as she died. They left her soon after, but her adult daughter returned and remained by her mother all night. When keepers removed the mother's body the next day, the chimpanzees remained calm and subdued. For several days they avoided sleeping on the platform where the female had died, even though it was normally a favored sleeping spot, and remained subdued for some time after the death.
Novel Nanoparticles Prevent Radiation Damage
ScienceDaily (Apr. 27, 2010) — Tiny, melanin-covered nanoparticles may protect bone marrow from the harmful effects of radiation therapy, according to scientists at Albert Einstein College of Medicine of Yeshiva University who successfully tested the strategy in mouse models. Infusing these particles into human patients may hold promise in the future.
Teaching a Foreign Language? Best Teach in the Accent of the Listener
ScienceDaily (Feb. 17, 2010) — Perception of second language speech is easier when it is spoken in the accent of the listener and not in the 'original' accent of that language, shows a new study from the University of Haifa. The study was published in the Journal of Psycholinguistic Research.
Many adult schools teaching second languages insist on exposing their students to the languages in their 'original' accents. However, this new study, carried out by Dr. Raphiq Ibrahim and Dr. Mark Leikin of the University of Haifa's Edmond J. Safra Brain Research Center for the Study of Learning Disabilities, Prof. Zohar Eviatar of the Department of Psychology and Prof. Shimon Sapir of the Department of Learning Disabilities, found that this system is not necessarily the best and certainly not the most expeditious.
