A new study has found that a faster metabolism is the main reason that humans were able to evolve bigger brains than other closely related apes. Humans burned 635 more calories per day than gorillas, and a whopping 820 more calories per day than the orangutans in the study.

Although the study findings seem promising, more research on the issue is required since the research was performed only on adults.

New cure for SMA?!


Spinal muscular atrophy (SMA) is a disease that causes progressive degeneration in the nerve cells that control muscles, thereby causing muscle weakness and eventually death. SMA affects approximately 200,000 people in the U.S., often children. Now, researchers at the University of Missouri are studying a subtype of SMA, spinal muscular atrophy with respiratory distress type 1 (SMARD1), and have developed a gene replacement therapy that can be used to treat and control the disease in the future.

SMARD1 is a rare genetic condition with high mortality rate that develops primarily between the ages of six weeks and six months. The condition targets the spinal cord and leads to atrophy of body muscles and paralysis of the diaphragm, which is responsible for breathing. As the disease progresses, children with a SMARD1 diagnosis become paralyzed and require continuous artificial ventilation. The average life expectancy of a child diagnosed with SMARD1 is 13 months. Currently, there is no cure or effective treatment for this disease.

“Monogenic diseases like SMARD1, a disease that is caused by one gene, are ideal for gene therapy since the goal of the therapy is to replace the missing or defective gene,” said Chris Lorson, an investigator in the Bond Life Sciences Center and a professor of veterinary pathobiology. “Our goals for this study were to develop a vector that would improve the outcomes of the disease and for the vector to be effective in a single dose.”

New tech from Carnegie Mellon makes it much easier to play ‘Angry Birds’ on your wrist.

Smartwatches walk a fine line between functionality and fashion, but new SkinTrack technology from Carnegie Mellon University’s Future Interfaces Group makes the size of the screen a moot point. The SkinTrack system consists of a ring that emits a continuous high-frequency AC signal and a sensing wristband that goes under the watch. The wristband tracks the finger wearing the ring and senses whether the digit is hovering or actually making contact with your arm or hand, turning your skin into an extension of the touchscreen.

If aliens sent you an encrypted binary message, could you answer? René Heller, an astrophysicist at the Max Planck Institute for Solar System Research, wants to hear from you.

Last month, Heller posed a hypothetical question as part of the #SETIDecryptChallenge: “Suppose a telescope on Earth receives a series of pulses from a fixed, unresolved source beyond the solar system,” he wrote. “It turns out the pulses carry a message.”

The encrypted message is a vast sea of 0’s and 1’s. You can see it here, but here’s a GIF for your convenience.

The debate over which bathroom transgender people can use has been taking over the Internet and our social conversations for weeks now, and it’s getting a bit ridiculous. Transgender people have always used the bathroom that they feel comfortable with, whether it’s the bathroom that belongs to the sex they were born with or not, and there have been no problems.

In the heat of this debate, Americans are not only divided on the issue but collectively distracted from bigger, more important issues, such as the fact that there are three nuclear disasters occurring throughout the nation that have been getting no media attention.

One major disaster that will soon come to head all started with a fire at the Bridgeton Landfill in Missouri that has been burning for five years. Despite this extremely long length of time, authorities say that this fire is nowhere close to being contained. What’s more is that St. Louis County officials have reported that they have an emergency plan in place because the fire is closing in on nuclear waste dump.

Autonomous robot surgeon prototype stitches pigs’ colons better than human and human-assisted robot surgeons:

In his proof-of-concept study, the STAR system stitched together two parts of a pig’s colon. The researchers likened this task to reconnecting a cut garden hose—and just like the hose, if the stitching is done imperfectly, the colon can be prone to leaks that can be life-threatening. Using the vision system and a pressure sensor at the end of the robotic arm, the STAR tool automatically placed sutures in the tissue to reconnect it, both in tissue in the lab and inside living pigs. The researchers then compared the STAR’s performance to that of a surgeon performing the same task with a laparoscopic tool as well as a robot-assisted surgery in which the surgeon controls the robot.

Comparing the uniformity of the sutures, number of mistakes and the highest pressure that the tissue could withstand without leaking, the STAR system performed better than the human and the human-directed robot. None of the living pigs had any complications from the operations.
