Cronobacter sakazakii is a harmful germ that can be found in powdered baby formula. It can cause very serious health problems in infants, such as meningitis and septicemia. Right now, it takes a long time and is complicated to check if the germ is in the formula. However, a new study has created a special test that uses a computer program to find the germ in the formula. This new method makes it easier and faster to find the germ, which is known for causing serious illness in babies. It helps make sure that baby formula is safe to use.

Scientists are using the imperfections in magnetic fields that confine a fusion reaction to improve and enhance the plasma in an approach outlined in a new paper in the journal Nature Communications. PPPL Physicist Seong-Moo Yang led the research team, which spans various institutions in the U.S. and South Korea. Yang says this is the first time any research team has validated a systematic approach to tailoring magnetic field imperfections to make the plasma suitable for use as a power source. These magnetic field imperfections are known as error fields.

Experimentalists and theorists have provided strong evidence for the creation of an exotic isotope, nitrogen-9, which has two neutrons and seven protons. This unbalanced ratio of protons to neutrons produces a nucleus that only survives for less than one-billionth of a nanosecond. The work also provides information on nitrogen-9’s mirror nucleus, helium-9, which has two protons to its seven neutrons.

Researchers have developed a new generation of high-performance DNA aptamers and highly accurate drug sensors for cocaine and other opioids. The sensors are drug specific and can detect trace amounts of fentanyl, heroin, and cocaine – even when these drugs are mixed with other drugs or with cutting agents and adulterants such as caffeine, sugar, or procaine.
