How Craig Venter Is Fighting Ageing with Genome Sequencing

Bioethics News - Thu, 05/05/2016 - 14:27

(Wired UK) – Eight years ago, Venter’s genome couldn’t even be used to tell you his eye colour. Yet modelling appearance is merely a visual demonstration, not the end goal, of HLi’s big-data genomics. The aim is to predict your future. To explain why some people’s cholesterol accumulates in their arteries to ultimately fatal levels, and others’ does not. To identify which women are likely to develop breast or ovarian cancer in later life. And to understand why some people develop Alzheimer’s and some continue to live a cognitively rich life at 90.

Unmanned Robot Surgery Works in Pig Trial

Bioethics News - Wed, 05/04/2016 - 14:51

(BBC) – An unmanned robot has been used to stitch together a pig’s bowel, moving science a step closer to automated surgery, say experts. Unlike existing machines, the Star robot is self-controlled – it doesn’t need to be guided by a surgeon’s hands. In tests on pigs, it at least matched trained doctors at mending cut bowel, Science Translational Medicine reports. But it is very early days and it remains to be seen if people would trust such a “hands-off” approach.

Funding: Donor Drugs

Bioethics News - Wed, 05/04/2016 - 14:41

(Nature) – In the past decade venture philanthropy has experienced a resurgence, with many foundations focused on new therapies. But the attributes that make this type of funding so effective can also stir up controversy or raise ethical questions. Philanthropic foundations are not accountable to the public, and some critics question whether wealthy benefactors have too much sway in medicine.

In Gaza, Hand Surgery Gets Remote Assistance from Beirut

Bioethics News - Wed, 05/04/2016 - 14:38

(Reuters) – At a hospital in northern Gaza, a young patient is being prepared for hand surgery as one of the doctors leading the operation watches on — from nearly 200 miles away in Beirut. In the Lebanese capital Doctor Ghassan Abu Sitta is guiding colleagues at Gaza’s Al-Awda hospital via an online interactive platform known as Proximie, which allows the medical teams to communicate and work together via tablet computers.

Human Embryos Grown in Lab for Longer than Ever Before

Bioethics News - Wed, 05/04/2016 - 14:33

(Nature) – Developmental biologists have grown human embryos in the lab for up to 13 days after fertilization, shattering the previous record of 9 days. The achievement has already enabled scientists to discover new aspects of early human development, including features never before seen in a human embryo. And the technique could help to determine why some pregnancies fail. The work, reported this week in Nature and Nature Cell Biology, also raises the possibility that scientists could soon culture embryos to an even more advanced stage. Doing so would raise ethical, as well as technical, challenges. Many countries and scientific societies ban research on human embryos that are more than 14 days old; in light of this, the authors of the studies ended their experiments before this point.

Researchers Find Bioreactor Support Whole Lung Regeneration

Bioethics News - Wed, 05/04/2016 - 14:30

(UPI) – It may be possible to grow new lungs for patients in need of a transplant using their own cells as a starter kit, according to researchers at Yale University. The researchers devised a mechanical system that mimics the body to allow whole lungs to grow at scale, described in a proof-of-concept study published in the journal BioResearch Open Access.

Why Women’s Eggs Run Out and What Can Be Done About It

Bioethics News - Wed, 05/04/2016 - 14:23

(The Conversation) – A recent report shows new healthy eggs can be made from stem cells. Stem cells are present in human embryos, as embryonic stem cells, and in most organs including the ovary. Alternatively, an induced form of stem cells can be obtained by treating mature cells with a cocktail of reagents in the laboratory. The procedures required to create new eggs out of stem cells are very complex and still experimental. There are ethical issues, such as the need to destroy a human embryo to obtain embryonic stem cells, and further experiments will be necessary to show there are no genetic or fertility problems with subsequent generations.

The Gene Editor CRISPR Won’t Fully Fix Sick People Anytime Soon. Here’s Why

Bioethics News - Wed, 05/04/2016 - 14:16

(Science) – This week, scientists will gather in Washington, D.C., for an annual meeting devoted to gene therapy—a long-struggling field that has clawed its way back to respectability with a string of promising results in small clinical trials. Now, many believe the powerful new gene-editing technology known as CRISPR will add to gene therapy’s newfound momentum. But is CRISPR really ready for prime time? Science explores the promise—and peril—of the new technology.

Nepal Bans Surrogacy, Leaving Couples with Few Low-Cost Options

Bioethics News - Wed, 05/04/2016 - 14:10

(New York Times) – The embryos belonged somewhere, but probably not in this empty fertility clinic in the capital of Nepal. For months, they had sat suspended in a tank of liquid nitrogen at the fertility center at the Grande City Clinic and Hospital, which until recently operated a robust surrogacy business that attracted would-be parents from around the world. But the embryos are now stuck in limbo after Nepal abruptly banned surrogacy in September.

MSF President to UN Security Council: “Stop These Attacks”

Bioethics News - Wed, 05/04/2016 - 14:01

(Medicins Sans Frontiers) – Excellencies, ladies and gentlemen, Last Wednesday, airstrikes obliterated Al Quds Hospital in Aleppo. They blew apart at least 50 men, women and children. It killed one of the last remaining paediatricians in the city. A murderous airstrike. There were almost 300 airstrikes in Aleppo over the last 10 days. Civilians, often in crowds, were repeatedly struck. What are individuals in wars today? Expendable commodities, dead or alive.
