Catnip is for pleasure and purpose, according to a new study

The main bioactive compound in catnip seems to protect cats from mosquitoes. It might protect humans, too.

  • For centuries, humans have observed that cats exhibit strange behaviors when exposed to catnip and silver vine.
  • A new study examined how the main bioactive compound in these plants affects cats' opioid systems and protects them against mosquito bites.
  • The findings suggest that the compound nepetalactol could be used to develop new mosquito repellents for humans.

Ginger may guard against the progression of some autoimmune diseases

A new study on mice showed that ginger may counter certain autoimmune disorders such as lupus and antiphospholipid syndrome.

  • A new Michigan Medicine study on mice suggests that the primary bioactive compound of ginger root, 6-gingerol, could help counter the autoimmune disorders lupus and antiphospholipid syndrome.
  • The researchers found that the mice had lower levels of NETs (which play a role in the pathogenesis of lupus and antiphospholipid syndrome by stimulating autoantibody formation) after being giving 6-gingerol.
  • 6-gingerol won't be able to be the primary therapy for individuals with lupus or active antiphospholipid syndrome, but the research team is eager to see if the natural supplement offers help to those at high risk for developing the diseases.

  • Antibiotic resistance is a big problem, but not many new drugs are currently under development.
  • A recent discovery may give us a new antibiotic that is effective against a wide range of germs, including those resistant to other drugs.
  • The new drug's mechanism also appears to signal the immune system, helping to amplify its response.
