Artificial eye that can see in the dark created by UW-Madison researchers

UW–Madison engineers have created an artificial eye that can see in the dark and be used for search-and-rescue robots, surgical scopes, telescopes and recreational purposes, including night photography. Hongru Jiang, a UW-Madison professor of computer and biomedical engineering and the study’s author, said he gained inspiration for the artificial eye from unique cells that make up the retina of elephant nose fish, according to a university release.

Female fruit flies adapt to male phallus

The fruit fly, as intolerable as they can seem, is integral to studying and understanding genetics. John Pool, a UW-Madison assistant professor in genetics, studies population genetics primarily by using fruit flies.

UW-Madison professor explores how Americans react to science

Members of the UW-Madison community met Tuesday night at the Wisconsin Institutes for Discovery to hear a lecture given by UW-Madison professor of life science and communication Dietram A.

UW-Madison professor Dave Pagliarini wins award for mitochondrial research

President Barack Obama announced earlier in February that the Director of Metabolism at the Morgridge Institute for Research Dave Pagliarini is one of the 105 recipients of the Presidential Early Career Award for Scientists and Engineers. The award, which was created in 1996, is given to scientists who show great potential in the early portion of their careers.

Fast Radio Bursts observed

The universe is a vast and mysterious space, filled with distant and puzzling objects, but UW-Madison physics professor Peter Timbie has played a huge role in helping to demystify it by giving us a deeper understanding of the incredibly rare cosmological phenomenon called Fast Radio Burst: a singular pulse of radio signal. Timbie and his lab work with understanding the early universe, using large radio telescopes to detect the signals emitted by distant pulsars, which are neutron stars that emit regular and repeated radio wave signals across the universe.  During a radio survey using the Green Bank Radio Telescope in Green Bank, Va., they heard that a research group in Australia had detected over ten Fast Radio Bursts, or FRBs.

Ask Ms. Scientist: sports fanatics and caffeine

Is there any science as to why some people get so emotionally involved while watching a sports game? What are the dangers of drinking too much coffee?

Ask Ms. Scientist: road salt and naps

What are the effects of road salt on the environment? How long is the perfect nap?

UW-Madison evolutionary biologist awarded Lewis Thomas Prize

Rockefeller University announced Thursday that Sean B. Carroll, UW-Madison evolutionary biologist and author, won the Lewis Thomas Prize for Writing about Science. The award was established in 1993 to honor individuals writing about science “whose voice and vision can tell us about science’s aesthetic and philosophical dimensions, providing not merely new information but cause for reflection, even revelation,” according to a university release.

Land arrangement alters water quality

The Yahara Watershed reaches around the city of Madison and its defining lakes. It’s a large stretch of land, spanning farms and forests and dotted by the occasional construction site that slowly reshapes and urbanizes its traditional farms and prairies.  In the center are five lakes, each one fed by the rain that flows down the periphery of the watershed and into the Yahara River, ultimately leading through the rivers and streams that join the Mississippi and drain into the Gulf of Mexico almost a thousand miles away.  In a Birge Hall lab seemingly isolated from that network of water that flows around it, Jiangxiao Qiu studied models of the region, observing data sets created from Department of Natural Resources mapping, UW-Madison’s Center for Limnology and other organizations.

Ask Ms. Scientist: windchill and chopping onions

How is the windchill index calculated? Why does chopping onions make me cry?

PTSD predator stress model reveals overactive neurotransmitter response

Post-traumatic stress disorder (PTSD) is a severe anxiety disorder that affects more and more people every day. Resulting from experiences of traumatic events, PTSD is characterized by intense recurring flashbacks and high emotions of fear when the patient is overly triggered by a normally mild stimulus.

Nelson Institute for Environmental Studies increases breadth in student education

With a variety of courses and flexible curriculum, the Nelson Institute for Environmental Studies offers students the broad education they need to collectively solve environmental problems.

Ask Ms. Scientist: chronic stress and staying warm

Dear Ms. Scientist,

Bill Gates excitedly awaits death, biopics

After seeing the most recent film about the life and career of Steve Jobs, Bill Gates, software pioneer and co-founder of Microsoft, is absolutely ecstatic about the biographical films he expects to come out about him after he dies. “It’s just so exciting to think about all the great movies they might make about me,” said Gates while energetically bouncing around in his seat.

Ask Ms. Scientist: Thanksgiving and study jams

Dear Ms. Scientist,

Rocks reveal an oxygenated ocean earlier than assumed

The oceans of the Archean were nothing like today’s vast blue pools. In fact, these oceans lacked free oxygen. Until recently, it was thought the oceans’ water columns were uniformly anoxic until the Great Oxidation Event, which occurred 2.4-2.2 billion years ago. However, researchers at UW-Madison have discovered evidence of free oxygen in Earth’s shallow oceans much earlier.
