Tiny Robotic Hand Has Strong Grip

Robotic Hand

Scientists have developed a pair of robotic hands that are both strong and sensitive

The tweezers can guide themselves to pick up and move individual cells without damaging them, and have a grip that can be as slight as 20 nanoNewtons of force. In fact, so advanced are the little grippers, that they can be hitched up to a microscope and, with the right software, function without human control. More below.

Study: Trans-Fats Linked to Breast Cancer

Trans-fats, which are being phased out of food because they clog arteries, may raise the risk of getting breast cancer, European researchers reported on Friday.

They found that women with the highest blood levels of trans-fats had about twice the risk of breast cancer compared to women with the lowest levels.

Your Aging Rate is Written in Your Bones

 Your Aging Rate is Written in Your Bones
Perhaps the aging process can’t be stopped. But it can be predicted – thanks to a new study,
which indicates that people may live longer and lead healthier lives as a result.

Researchers at Tel Aviv University have carried out the study and found that how fast one will age is written in one’s bones because the speed of physical aging is strongly influenced by genetics. They have also developed a biological marker that represents the age of a body’s bones.

Targeting Delivery for Nanoparticles

 Targeting Delivery for Nanoparticles

Conventional chemotherapy can wreak havoc on healthy tissue, causing painful side effects, and it’s not always effective. Nanotechnology-based methods to deliver these drugs only to cancerous cells have shown promise, but they don’t work for all cancers. Now a handful of research groups are developing more-complex approaches that use microscopic carriers to deliver a variety of particles–including drugs, molecular tags that target tumors, and imaging agents to monitor and destroy cancer cells. In theory, these microscopic delivery vehicles would evade the body’s defenses and target blood vessels near a tumor, then release their payload.

Super Antibiotics Could Come From Alligator Blood

Antibiotics are a seriously important part of modern medicine, but due to certain infections becoming antibiotic-resistant, they can’t be doled out as plentifully as some would like. That might change in the near future, however, due to a new advancement from an unlikely source: the blood of alligators.
