Genetically speaking, mammals are more like their fathers

You might resemble or act more like your mother, but a novel research study reveals that mammals are genetically more like their dads. Specifically, the research shows that although we inherit equal amounts of genetic mutations from our parents — the mutations that make us who we are and not some other person — we actually ‘use’ more of the DNA that we inherit from our dads. —> Read More Here

91-Year-Old Is Living Her Dream As A Tech Designer At Silicon Valley Firm

A nonagenarian has started a new career as a valuable part of Silicon Valley’s tech world, bringing her years of wisdom to the industry.

When Barbara Beskind was a child, she wanted to become an inventor. At 91 years old, she’s living that dream as a tech designer for IDEO, a firm in Palo Alto, California, according to Beskind became an employee last year and has since been working primarily on projects that relate to aging.

She says that her age has been beneficial to her.

Age is not a barrier to performance. Live life as an adventure, and expect change and endorse it, embrace it,” Beskind told “I think the beauty of being 91 is that you can look back and see how the little pieces fit into the big pieces of life, and life is a complete puzzle.”

Beskind had wanted to pursue a career as an inventor after high school but the job required an engineering degree, NPR reported. Her guidance counselor told her that women weren’t accepted by engineering schools, so Beskind joined the army and became an occupational therapist instead.

Two years ago, she saw an interview in —> Read More Here

These Ultra-Small Bacteria May Be The Tiniest Life Forms On Earth

size limit life

So, this is about as small as life can get.

Scientists from Lawrence Berkeley National Laboratory and the University of California, Berkeley have captured the first detailed microscopic images of so-called “ultra-small bacteria” that are believed to represent the lowest size limit possible for life on Earth. Scientists have debated the existence of these tiny bacteria for decades since there was never such a detailed observation of the weird microbes–but the debate now seems to be over.

(Story continues below image.)

This image reveals the internal structure of an ultra-small bacterium. The cell has a dense interior compartment and a complex cell wall. The scale bar is 100 nanometers.

“These newly described ultra-small bacteria are an example of a subset of the microbial life on Earth that we know almost nothing about,” Dr. Jill Banfield, a senior scientist in Berkeley Lab’s Earth Sciences Division, who helped research the bacteria, said in a written statement. “They’re enigmatic. These bacteria are detected in many environments and they probably play important roles in microbial communities and ecosystems. But we don’t yet fully understand what these ultra-small bacteria do.”

For their research, the scientists filtered groundwater collected in Rifle, Colo., down to 0.2 —> Read More Here

Pens filled with high-tech inks for do-it-yourself sensors

A new simple tool developed by nanoengineers at the University of California, San Diego, is opening the door to an era when anyone will be able to build sensors, anywhere, including physicians in the clinic, patients in their home and soldiers in the field. The team from the University of California, San Diego, developed high-tech inks that react with several chemicals, including glucose. They tested the sensors to measure glucose and pollution. —> Read More Here

Fighting a worm with its own genome

Tiny parasitic hookworms infect nearly half a billion people worldwide — almost exclusively in developing countries — causing health problems ranging from gastrointestinal issues to cognitive impairment and stunted growth in children. By sequencing and analyzing the genome of one particular hookworm species, Caltech researchers have uncovered new information that could aid the fight against these parasites. The results of their work were published online in the March 2 issue of the journal Nature Genetics. —> Read More Here
