Scientists find fossil of shark-like ancient sea creature

Scientists find fossil of shark-like ancient sea creature

A team of scientists claimed to have found fossilized remains of a new fish species that they believe looked and ate like a shark.

An analysis of the fossil revealed that it belonged to a previously unknown bony, sharp-toothed species that would have been nearly six-feet or 1.83 meters in length with long jaws and multiple layers of sharp teeth.

The long jaw and layers of teeth on the ancient fish called Birgeria Americana suggest that members of this species would have chomped down on its prey prior to swallowing it whole, like sharks.

FDA approves new drug to treat all forms of hepatitis C

FDA approves new drug to treat all forms of hepatitis C

The U.S. Food & Drug Administration (FDA) has finally approved the first drug to treat all forms of hepatitis C for patients who weren’t cured by prior treatment.

The just approved pill combination known as Mavyret (glecaprevir and pibrentasvir) is from AbbVie Inc. Mavyret joins a couple of other AbbVie hepatitis C drugs that are already of the market.

The approval of the new drug is for all sorts of hepatitis C. Its approval will provide doctors and patients with more options. Insurers will get more leverage to mangle discounts out of firms to cover the pricey drugs.

Astronomers detect stratosphere on a distant exoplanet

Astronomers detect stratosphere on a distant exoplanet

A team of American astronomers have discovered evidence for existence of a stratosphere on an exoplanet, a planet outside our solar system.

It may be noted here that a stratosphere is a layer of atmosphere on a planet in which temperature rises with increase in altitude.

The scientists detected the stratosphere on WASP-121b, a planet outside our solar system dubbed a “hot Jupiter,” which is 900 light-years away from Earth.

Researchers detect never-before-seen neutrino interactions

Researchers detect never-before-seen neutrino interactions

Using the world’s smallest neutrino detector, a team of scientists at the Department of Energy’s Oak Ridge National Laboratory (ORNL) has detected never-before-seen neutrino interactions.

The detection of the elusive, electrically neutral particles interacting only weakly with matter provided compelling evidence for a process predicted by theorists more than four decades ago.

The breakthrough was made as part of the COHERENT experiment, a collaboration of eighty researchers from nineteen institutions and four nations.

Study reveals link between variations in immune-system proteins and CFS

Study reveals link between variations in immune-system proteins and CFS

A team of researchers has spotted a strong link between variations in seventeen immune-system signaling proteins and chronic fatigue syndrome (CFS), which is also known as myalgic encephomyelitis (ME).

The researchers also found evidence that inflammation is a key driver of ME/CFS, which has eluded researchers for decades.

Senior author Mark Davis, a professor of immunology & microbiology, said that their study showed that it an inflammatory disease.

Schumer urges FDA to probe fast-food packaging health effects

Schumer urges FDA to probe fast-food packaging health effects

Senate minority leader Chuck Schumer on Sunday urged the U.S. Food & Drug Administration (FDA) to launch a probe into the consequences of using phthalates in fast-food packaging.

Phthalates can be described as a chemical that has been banned in other household products. But its ongoing use in fast-food wrappers, cups and cartons has raised concerns among health experts and many politicians.

In a letter to the federal agency, Schumer underlined that six forms of the controversial chemical have already been banned from being used in toys and child care products.

FDA preparing to cut nicotine levels in cigarettes

In yet another effort to fight back addition to smoking, the U.S. Food & Drug Administration (FDA) is aiming to lower nicotine levels in cigarettes.

On Friday, FDA Chief Scott Gottlieb directed staff to develop new regulations on levels of nicotine in smoking products. The federal government has proposed cutting levels of nicotine in cigarettes so that these products become less addictive.

Addressing agency staff, Gottlieb said, “A renewed focus on nicotine can help us to achieve a world where cigarettes no longer addict future generations of our kids.”

E-cigarette use helps some people quit smoking: Study

E-cigarette use helps some people quit smoking: Study

Linking e-cigarette to an impressive rise in the numbers of people quitting smoking, a new study found that smokers who use e-cigarettes are more likely to kick the habit than others. Most of the campaigns against smoking have not been as successful as local governments and health authorities have planned.

Engine for NASA’s SLS Megarocket successfully tested

Engine for NASA’s SLS Megarocket successfully tested

NASA has successfully test-fired the RS-25 rocket engine for its future megarocket, the Space Launch System (SLS), for nearly 8.5 minutes.

Agency officials announced that the test, which was the third in a row, was conducted on the A-1 Test Stand at NASA’s Stennis Space Center close to Bay St. Louis in Mississippi.

The highly-powerful RS-25 engine will be used to power the upcoming SLS, which is being built for conducting deep space missions.
