Why Did Humans Start Eating Meat?

Humans have been hunter-gatherers for most of our existence as a species and hunting has long been seen as a key human adaptation, thought to have influenced our anatomy, physiology, and behavior, indeed, a force in our evolution as a species. CARTA brings experts from across the globe to explore evidence pertaining to understanding the origins of hominin hunting and where this understanding can lead future research.

Sally Ride Forever!

When the United States Postal Service chose UC San Diego as the site to unveil its new Sally Ride Forever postage stamp, the UCSD community could not have been more thrilled. Ride, the first American woman in space, taught physics at UCSD after finishing her stellar run at NASA and then, through Sally Ride Science, inspired a new generation to embrace STEM. As seen in the Stamp Dedication Ceremony [uctv.tv/shows/33665] and the Women in Leadership [uctv.tv/shows/33160] discussion that followed, Dr. Ride’s fellow trailblazers Billie Jean King, Ellen Ochoa, Lynn Sherr and Condoleezza Rice, proudly honored the memory of their late friend.

Music Is Powerful

“I say I survived for a reason: to tell my story. I believe that…Music is powerful. It is the only thing that can speak into your mind, your heart and your soul without your permission.”
– Emmanuel Jal

The Second Sudanese Civil War from 1983 to 2005 was one of the longest and bloodiest civil wars on record, yet it barely registered in Western media. The war resulted in the deaths of roughly two million people and the repeated displacement of over four million others in southern Sudan alone, constituting one of history’s largest refugee crises. Among the atrocities committed during the war were slavery, rapes, mutilations, mass killings, and the forced enlistment of children as soldiers by all sides.

Emmanuel Jal was one such child soldier. Born in what is now South Sudan, Jal was a young child when the civil war broke out. After his father joined the rebel army (SPLA) and his mother was killed by loyalist soldiers, Jal joined the thousands of Sudanese children travelling to Ethiopia, hoping to escape the conflict and find education and opportunity. Along the way, however, many of the children, Jal included, were forcibly recruited by the SPLA and taken to military training camps where they were taught to kill, in Jal’s words, “mercilessly and efficiently.”

For the next several years Jal and his comrades fought with the SPLA, first in Ethiopia and then back in Sudan, until the fighting and deprivations became unbearable. Jal and some of his friends ran away, and for three months they were constantly on the move, stealing food and dodging roving patrols. Eventually Jal met a British aid worker who adopted him and smuggled him to Kenya, where he attended school. It was in the slums of Nairobi that Jal became a community activist. He also discovered hip-hop and the power of the spoken word; singing and rapping became a form of therapy to ease the pain of his experiences, and his life’s course was set. Over time Jal developed a unique form of hip-hop, seemingly conventional in form but layered with African beats and sung/chanted over African-inspired choruses.

Unlike many of his American counterparts, Jal sees hip-hop as a powerful vehicle to lobby for social justice and political change in a positive manner, rather than as a method of pursuing street credibility. His raps and spoken word pieces emphasize unity and common humanity as motivators for young people and weapons in the fight against the scourges of ethnic and religious divisions, such as those that plague his homeland. This hopeful outlook, combined with his many humanitarian activities, dovetails neatly with the goals of UC San Diego’s Eleanor Roosevelt College, and marks Jal as a suitably inspirational figure to help celebrate the College’s 30th Anniversary.

His dynamic performance is by turns thought-provoking and uplifting, at times almost somber, but also leavened with humor and, yes, with fun. As Jal himself puts it, “Life without fun is no life at all,” a remarkable perspective from one who has suffered much but has refused to give in to bitterness or cynicism.

Bring Back Mammoths

Remember Dolly the sheep? How in 1996 she made international news as the first cloned mammal? Now, imagine using those techniques to bring back extinct animals, such as the mammoth or the passenger pigeon. While the concept may no longer be science fiction, the costs and consequences of this research are still unknown. MacArthur Award recipient and evolutionary biologist Beth Shapiro of UC Santa Cruz discusses the scientific and ethical questions raised by what’s known as Ancient DNA research in this fascinating talk presented by the new Institute for Practical Ethics at UC San Diego.

Losing the Nobel Prize

When Alfred Nobel stipulated the creation of the Nobel Prize in 1895, the inventor of dynamite could hardly have guessed that the award – considered by many to be the world’s most prestigious honor – would often come at the expense of the very careers and the disciplines Nobel sought to promote. Per Nobel’s will the Prize is ostensibly awarded to those who “have conferred the greatest benefit on mankind,” but it has arguably fallen short of that commendable goal on several occasions.

In Losing the Nobel Prize, his provocative and incisive critique of the award, physicist and cosmologist Brian Keating addresses what he calls the Nobel’s “systematic biases,” noting that by its nature the Prize discourages communal efforts among scientists, and during its history has lauded such questionable pursuits as lobotomy and eugenics. Recipients have included Nazis and war criminals, but surprisingly few women. Upon reflection, perhaps not so surprising; Nobel’s will states that:

It is my express wish that in awarding the prizes no consideration whatever shall be given to the nationality of the candidates, so that the most worthy shall receive the prize, whether he be a Scandinavian or not. [Emphasis added]

Since its inception, only two women have been awarded the physics prize, and none in over fifty years.

Keating is uniquely equipped to offer a perspective on the Nobel Prize. He is the inventor of BICEP (Background Imaging of Cosmic Extragalactic Polarization), the most powerful cosmological telescope ever made, and co-leader of the team that conducted the BICEP2 experiments that lead to discovery of “the spark that ignited the Big Bang.” After much drama and debate that discovery was subsequently proven to be a cosmic mirage, but in the interim Keating found himself drawn into the headlong pursuit of the Nobel medal, encountering competitiveness, intrigue, and naked ambition along the way. The lessons Keating learned in losing the Nobel Prize serve as a cautionary tale about abandoning the collaborative spirit in pursuit of a near-unobtainable prize, but also as a prescription for radical, much-needed reform of the world’s most coveted award.

Following his talk Keating chats with David Brin, noted science fiction author and futurist, in a lively conversation about the nature of scientific enquiry, the merit of awarding scientific prizes, the importance of collaboration, the need for transparency, and the urgent need to improve communication between scientists, policy makers, and the general public. Above all, both men stress that those lessons learned by Keating and outlined in his book may ultimately prove to be more valuable than the prize itself.
